As shown in FIGS. 1-31, an embodiment of a first aspect of the present application provides an air-source heat pump air conditioner, which includes a housing 200, an electric control box 100, an air side heat exchange mechanism, a hydraulic mechanism, and a compressor 400. The housing 200 is internally provided with a first partition 201 and a second partition 202. The first partition 201 divides the housing 200 into an upper chamber 203 and a lower chamber, and the second partition 202 divides the lower chamber into a first chamber 204 and a second chamber 205. The electric control box 100 is arranged inside the upper chamber 203, the air side heat exchange mechanism is arranged inside the first chamber 204, and the hydraulic mechanism and the compressor are arranged inside the second chamber 205.
The housing 200 is an installation carrier for the members of the air-source heat pump air conditioner, and it can be of any shape. In this embodiment, the housing 200 has a rectangular shape, and includes a top wall, a bottom wall 206, and side walls. Upper ends of the side walls are connected to the top wall, and lower ends of the side walls are connected to the bottom wall 206. The side walls cooperate with the top wall and the bottom wall 206 to enclose a chamber for accommodating functional members. The side walls include a rear side wall, a left side wall, a front side wall, and a right side wall, which are connected end-to-end in sequence. In order to facilitate the disassembly of the members inside the housing, the side walls can usually be designed in a detachable manner.
It should be noted that the definitions involved in this embodiment, such as upper, lower, front, rear, left and right, are based on the orientation of the air-source heat pump air conditioner after it is installed in the usage environment. Specifically, the side of the air-source heat pump air conditioner that is near buildings such as a wall is the rear side, the side opposite to the rear side is the front side, the other horizontal direction perpendicular to the front-and-rear direction is the left-and-right direction, and the vertical direction is the up-and-down direction. In this embodiment, the top wall is located above the bottom wall 206, and the orientational words in the rear side wall, left side wall, front side wall and right side wall have certain orientational definitions. That is, the rear side wall is the side wall of the housing 200 that faces the rear, the left side wall is the side wall of the housing 200 that faces the left, the front side wall is the side wall of the housing 200 that faces the front, and the right side wall is the side wall of the housing 200 that faces the right.
Referring to FIGS. 1 and 2, the air side heat exchange mechanism includes an air side heat exchanger 310, which is arranged inside the first chamber 204. The hydraulic mechanism includes a water side heat exchanger 600, which is arranged inside the second chamber 205.
In order to ensure the heat exchange efficiency between the refrigerant and air in the air side heat exchanger 310, generally, the air-source heat pump air conditioner can also be provided with a fan blade assembly 300 corresponding to the air side heat exchanger 310, and the fan blade assembly 300 is arranged inside the first chamber 204. Specifically, the air side heat exchanger 310 can be arranged outside of the fan blade assembly 300, as shown in FIGS. 1 and 2. In this embodiment, the air side heat exchanger 310 is arranged in an L-shape inside the first chamber 204, and is located near the left side wall and the rear side wall that form the first chamber 204. The air side heat exchanger 310 can be a finned heat exchanger.
The fan blade assembly 300 is used to promote air flow. The fan blade assembly 300 can be an assembly such as an axial flow fan, which includes fan blades and a driving member. The driving member can be in the form of a motor in cooperation with a transmission member. The driving member is connected to the fan blades to drive them to rotate, so that air flows around the air side heat exchanger 310, allowing the air side heat exchanger to come into contact with the flowing air to improve heat exchange efficiency.
The water side heat exchanger 600 includes a refrigerant pipeline and a water flow pipeline. Typically, an expansion valve can also be arranged between the refrigerant pipeline of the water side heat exchanger 600 and the air side heat exchanger 310 to convert high-pressure gas into low-pressure gas. The air-source heat pump air conditioner can achieve both cooling and heating.
During the heating process of the air-source heat pump air conditioner, the compressor 400, the refrigerant pipeline of the water side heat exchanger 600, the expansion valve, and the air side heat exchanger 310 are sequentially connected in series through refrigerant pipes, forming a closed circuit. The working principle of heating is roughly as follows: the compressor 400 delivers high-temperature and high-pressure gaseous refrigerant to the refrigerant pipeline of the water side heat exchanger 600. The refrigerant in the refrigerant pipeline exchanges heat with the water flow in the water flow pipeline. The refrigerant pipeline outputs low-temperature and high-pressure (the low temperature is defined relative to the high temperature, and the low temperature can also be considered as conventional medium temperature) liquid refrigerant. The low-temperature and high-pressure liquid refrigerant is converted into low-pressure liquid refrigerant through the expansion valve. The liquid refrigerant vaporizes and absorbs heat in the air side heat exchanger 310 before entering the compressor 400, completing a heating and heat exchange process.
During the cooling process of the air-source heat pump air conditioner, the compressor 400, the air side heat exchanger 310, the expansion valve, and the refrigerant pipeline of the water side heat exchanger 600 are sequentially connected in series through the refrigerant pipes, forming a closed circuit. The working principle of cooling is roughly as follows: the compressor 400 delivers high-temperature and high-pressure gaseous refrigerant to the refrigerant pipeline of the air side heat exchanger 310. The refrigerant in the air side heat exchanger 310 exchanges heat with air, and then low-temperature and high-pressure liquid refrigerant is output. The low-temperature and high-pressure liquid refrigerant is converted into low-pressure liquid refrigerant through the expansion valve. The liquid refrigerant flows into the refrigerant pipeline of the water side heat exchanger 600. In the water side heat exchanger, the liquid refrigerant exchanges heat with the water flow in the water flow pipeline, vaporizes, absorbs heat, and then enters the compressor 400, completing a cooling and heat exchange process.
In the heating process, the air side heat exchanger is equivalent to an evaporator, and in the cooling process, the air side heat exchanger is equivalent to a condenser. The switching between cooling and heating processes can be achieved by connecting a four-way valve to a refrigerant outlet of the compressor.
The water flow pipeline of the water side heat exchanger 600 can also be connected with a water pump 500 and a water delivery pipeline. The water delivery pipeline is communicated with the water flow pipeline of the water side heat exchanger 600, and the water pump is arranged on the water delivery pipeline. The water pump 500 can drive water to circulate in the water flow pipeline, and can also be arranged in the second chamber 205.
In the air-source heat pump air conditioner of this embodiment, the housing 200 is divided into the upper chamber 203 and the lower chamber by the first partition 201, and the lower chamber is further divided into the first chamber 204 and the second chamber 205 by the second partition 202, so that members such as the electric control box 100, the air side heat exchange mechanism, the hydraulic mechanism, and the compressor 400 can be arranged in separate chambers, making the installation convenient and improving space utilization. By arranging the electric control box 100 in the upper chamber 203, arranging the air side heat exchange mechanism in the first chamber 204, and arranging the hydraulic mechanism and the compressor in the second chamber 205, the disassembly and maintenance of the electric control box 100 is facilitated, and the centers of gravity of the air side heat exchange mechanism, the hydraulic mechanism and the compressor 400 are made lower, with better stability. The whole machine has a compact structure and occupies less space.
The second chamber 205 and the first chamber 204 can be arranged in sequence in the vertical direction or horizontal direction. In this embodiment, in order to avoid the height of the housing 200 being too high and to make reasonable use of the lateral space, referring to FIGS. 1, 2 and 24, the second chamber 205 and the first chamber 204 are arranged side by side in the horizontal direction.
Specifically, the second chamber 205 and the first chamber 204 can be arranged in sequence in the left-and-right direction of the housing 200; the first chamber 204 can be located on the left side of the second chamber 205, and the first chamber 204 can also be located on the right side of the second chamber 205. The second chamber 205 and the first chamber 204 can also be arranged in sequence in the front-and-rear direction of the housing 200; the first chamber 204 can be located on the rear side of the second chamber 205, and the first chamber 204 can also be located on the front side of the second chamber 205.
Referring to FIGS. 1, 2, and 22, in this embodiment, the second chamber 205 is located on the right side of the first chamber 204, that is, the first chamber 204 is formed on the left side of the second partition 202, and the second chamber 205 is formed on the right side of the second partition 202.
In an implementation, the first partition 201 is fixed to inner side surfaces of the side walls, the upper chamber 203 is formed between the top wall and the first partition 201, and the lower chamber is formed between the bottom wall 206 and the first partition 201; the second partition 202 is connected between the first partition 201 and the bottom wall 206; the first chamber 204 is formed between the second partition 202 and a side wall (the left side wall and a part of the rear side wall located on the left side of the second partition 202) located on one side of the second partition 202, and the second chamber 205 is formed between the second partition 202 and a side wall (the right side wall and a part of the rear side wall located on the right side of the second partition 202) located on the other side of the second partition 202.
Optionally, the top wall, the bottom wall 206 and the first partition 201 are arranged in parallel, the side walls are arranged perpendicular to the bottom wall 206 and the top wall, and the second partition 202 is arranged perpendicular to the top wall and the bottom wall 206, thereby forming a relatively square first chamber 204 and second chamber 205, which facilitates the arrangement and installation of corresponding members.
It should be noted that according to design requirements, the bottom wall 206, the top wall and the first partition 201 may not be arranged in parallel. For example, the first partition 201 may be inclined, while the bottom wall 206 and the top wall are horizontally arranged; the side walls are also not limited to being perpendicular to both the bottom wall 206 and the top wall, for example, the side walls may be inclined; the second partition 202 may also be inclined.
When the first chamber 204 and the second chamber 205 are horizontally arranged in sequence, optionally, the water side heat exchanger 600 can be placed on the bottom wall 206 corresponding to the second chamber 205, and the compressor 400 can be placed above the water side heat exchanger 600.
Specifically, as shown in FIGS. 1, 2 and 24, a first support member 210 is also provided inside the housing 200. The first support member 210 can be in the form of a plate, a rod, or a frame structure. The second partition 202 is connected to the first support member 210, and an installation space for installing the water side heat exchanger 600 is formed between the bottom wall 206 and a lower side of the first support member 210. An upper side of the first support member 210 is provided with a first support position 2101 for installing the compressor 400.
The water side heat exchanger 600 can slide laterally along the bottom wall 206 into the installation space, and the compressor 400 can be fixed to the first support position 2101 by screws.
The second partition 202 is installed on the bottom wall 206 and located inside the housing 200, that is, the second partition 202 is located on a side surface of the bottom wall 206 that faces upward. By installing the second partition 202 on the bottom wall 206, the bottom wall 206 can provide support for the second partition 202. There are various structural forms of the second partition 202, including a rectangular plate with a rectangular cross section, a T-shaped plate with a T-shaped cross section, a U-shaped plate with a U-shaped cross section, a H-shaped plate with a H-shaped cross section, and a L-shaped plate with a L-shaped cross section, etc. The second partition 202 can be a structure that is integrally formed with the bottom wall 206, or it can be installed on the bottom wall 206 through welding, screw fixation, snap-fit, etc.
The structural form of the first support member 210 can also be configured in various ways as needed, such as a rectangular plate, an elliptical plate, an irregular plate, and so on. The second partition 202 and the first support member 210 can be fixed to each other. Specifically, the second partition 202 and the first support member 210 may be connected in a non-detachable way, which can be achieved by welding the second partition 202 and the first support member 210, or by integrally forming the second partition 202 and the first support member 210. The second partition 202 and the first support member 210 may also be connected in a detachable way, which can be achieved by screwing or snap-fitting the second partition 202 with the first support member 210, or by abutting and supporting the first support member 210 on the second partition 202, etc.
The first support member 210 can be connected to the second partition 202 in the middle of the first support member 210, and two ends of the first support member 210 are respectively positioned away from the second partition 202; at this time, the first support member 210 and the second partition 202 form a cross shaped cross arrangement. Referring to FIG. 4, the first support member 210 can be connected to the second partition 202 at one end of the first support member 210, and the other end of the first support member 210 is positioned away from the second partition 202; at this time, the first support member 210 is located on one side of the second partition 202. Arranging the first support member 210 on one side of the second partition 202 is more advantageous for the arrangement of members of the air-source heat pump air conditioner, so this embodiment is mainly explained with the first support member 210 being connected to the second partition 202 at one end of the first support member 210.
The first support member 210 is supported by the second partition 202, and under the support of the second partition 202, one end of the first support member 210 that is away from the second partition 202 can be suspended and can support the compressor 400. That is, the first support member 210 can support the compressor 400 by solely relying on the action of the second partition 202. In other words, the first support member 210 can independently support the compressor 400 under the support of the second partition 202. Therefore, the end of the first support member 210 that is away from the second partition 202 may not be provided with a corresponding support structure. Accordingly, a side of the installation space that is away from the second partition 202 will not be restricted by the support structure. The water side heat exchanger 600 can enter and exit the installation space from the side away from the second partition 202, which facilitates the disassembly and installation of the water side heat exchanger 600 in the second chamber 205, and improves the convenience and efficiency of maintenance and replacement operations of the water side heat exchanger 600 and the compressor 400.
In a specific implementation of this embodiment, the second partition 202 of this embodiment is arranged perpendicular to the bottom wall 206, and the first support member 210 is arranged in parallel to the bottom wall 206.
Referring to FIGS. 4, 5, and 7, the bottom wall 206 is arranged in the horizontal direction, and the second partition 202 extends in the vertical direction (i.e., in the up-and-down direction). One end of the second partition 202 is fixedly connected to the bottom wall 206. The first support member 210 is arranged in the horizontal direction and located above the bottom wall 206. One end of the first support member 210 is connected to the second partition 202.
It can be understood that in this embodiment, the space formed for installing the water side heat exchanger 600 is relatively square by arranging the second partition 202 vertically and arranging the first support member 210 and the bottom wall 206 in parallel, which is advantageous for the installation of the water side heat exchanger 600. In addition, the first support member 210 and the bottom wall 206 are arranged in parallel, that is, horizontally, which also facilitates the stable support of the compressor 400.
It should be noted that the arrangement of the second partition 202 and the first support member 210 in this embodiment is not limited to the way in which the second partition 202 is perpendicular to the bottom wall 206, and the first support member 210 is parallel to the bottom wall 206. According to actual spatial arrangement requirements, the second partition 202 can also be inclined on the bottom wall 206, and the first support member 210 can also be inclined.
In an installation manner of the second partition 202 and the first support member 210, multiple fixed positions are provided on the second partition 202, and the number of fixed positions is not less than three. Successive connecting lines of the multiple fixed positions are arranged in a polygonal shape, that is, at least one of the multiple fixed positions is non-collinear with the other two of the multiple fixed positions in the horizontal direction.
It can be understood that one of the fixed positions is non-collinear with the other two of the fixed positions in the horizontal direction, so that at least a triangular support can be formed, and when the first support member 210 is arranged on the second partition 202, even if the end of the first support member 210 that is away from the second partition 202 is suspended, the first support member 210 still has good support stability. Specifically, there can be three fixed positions provided on the second partition 202, which are scattered on the same horizontal plane and connected in sequence to form a triangle, i.e., the three fixed positions are not collinear. There can also be four fixed positions provided on the second partition 202; at this time, they can be scattered on the same horizontal plane and connected in sequence to form a quadrilateral or triangle.
It should be noted that more than four fixed positions can also be provided on the second partition 202, which will not be listed one by one herein. Meanwhile, the multiple fixed positions are not limited to being scattered on the same horizontal plane, and they can also have a certain height difference in the vertical direction, as long as they can stably support the first support member 210.
The fixed positions may have various structures. Specifically, the fixed positions can be protrusions protruding from the second partition 202. At this time, the first support member 210 can be supported on the protrusions, and the first support member 210 can be fixedly connected to the protrusions by screws or other means. The first support member 210 can also simply abut on the protrusions through the support of the protrusions. The fixed positions can also be grooves 213 provided on the second partition 202. At this time, the first support member 210 is provided with bulges corresponding to the grooves 213, and the first support member 210 is connected to the second partition 202 by snap-fitting the bulges in the grooves 213. The fixed positions can also be fixed holes provided on the second partition 202, and the first support member 210 is directly connected to the second partition 202 by passing screws and the like through the corresponding structures on the first support member 210 and the fixed holes.
Optionally, referring to FIGS. 4, 5, and 7, in this embodiment, the second partition 202 includes a second support surface 2022 and a first support surface 2021. The second support surface 2022 and the first support surface 2021 are connected to each other and arranged at an angle. The first support surface 2021 is provided with a first support sub part 2023, and the second support surface 2022 is provided with a second support sub part 2024. The second support sub part 2024 and the first support sub part 2023 are located in a space formed by the second support surface 2022 and the first support surface 2021, respectively. The first support sub part 2023 is connected to the first support surface 2021, and the second support sub part 2024 is connected to the second support surface 2022. The second support sub part 2024 and the first support sub part 2023 form a support part for supporting the first support member 210.
As shown in FIGS. 4, 5, and 7, the second support surface 2022 and the first support surface 2021 can both extend in the vertical direction, and one side edge of the first support surface 2021 and one side edge of the second support surface 2022 are aligned and connected. The first support surface 2021 and the second support surface 2022 are arranged perpendicular to each other. The first support sub part 2023 can be installed on the first support surface 2021 by snap-fit, welding, and screwing, etc., and the second support sub part 2024 can also be installed on the second support surface 2022 by snap-fit, welding, and screwing, etc. The first support member 210 can be installed on the first support sub part 2023 and the second support sub part 2024 by screwing, welding and snap-fit, etc.
Further, in this embodiment, a support surface is provided above the first support sub part 2023, and a support surface is also provided above the second support sub part 2024. The support surfaces extend horizontally and are in horizontal abutment with the first support member 210, which is equivalent to that the support surfaces form multiple fixed positions.
In order to improve the support stability of the first support member 210, as shown in FIG. 5, the extending length of the first support sub part 2023 in the direction perpendicular to the second support surface 2022 is relatively long, and the second support sub part 2024 is arranged at one end of the second support surface 2022 that is away from the first support surface 2021.
In this embodiment, as shown in FIG. 6, two screw holes 2025 are provided on the first support sub part 2023, and one screw hole 2025 is provided on the second support sub part 2024. The first support member 210 is fixed to the second support sub part 2024 and the first support sub part 2023 by passing screws through the three screw holes 2025.
It should be noted that the fixed positions can be set on the second support sub part 2024 and the first support sub part 2023, or the second support sub part 2024 and the first support sub part 2023 themselves form multiple fixed positions. In this embodiment, the fixed position formed on the first support sub part 2023 is a first fixed position, and the fixed position formed on the second support sub part 2024 is a second fixed position.
In an implementation, the water pump 500 is arranged above the water side heat exchanger. Specifically, the water pump 500 can be located on one side of the compressor 400 in the horizontal direction, that is, the water pump 500 and the compressor 400 are arranged in sequence in the horizontal direction.
The first support member 210 of this embodiment is also provided with a second support position 2102, which is arranged side by side with the first support position 2101 in the horizontal direction, and which is used for installing the water pump.
Referring to FIGS. 10, 12, and 13, the first support member 210 is roughly arranged in an L-shape. A wider end of the first support member 210 is the first support position 2101, and is used for installing the compressor 400; a narrower end of the first support member 210 is the second support position 2102, and is used for installing the water pump 500.
It can be understood that the first support position 2101 and the second support position 2102 are formed by the first support member 210, so that the compressor and the water pump (i.e., the water pump 500 and the compressor 400) can be installed on the first support member 210 simultaneously, which is advantageous for the compact arrangement of the members, thereby reducing the volume and occupied space of the housing 200.
Due to the relative high probability of disassembling and repairing the water pump 500, the second support position 2102 can be set on a side of the first support position 2101 that is away from the second partition 202, that is, the second support position 2102 can be set near the side wall of the housing 200, so that the water pump 500 can be disassembled and repaired after removing the side wall of the housing 200.
Optionally, in order to facilitate the installation of the water pump 500, the air-source heat pump air conditioner of this embodiment is also provided with a second support member 220 and a first fixing member 221. The first fixing member 221 is arranged on the second support member 220, that is, the water pump 500 is installed on the second support member 220. The water pump 500 can be specifically fixed to the second support member 220 by screws. The first support member 210 is provided with a second fixing member 211, and the second support member 220 can slide along a plate surface of the first support member 210 and can slide to the second support position 2102. After the second support member 220 slides to the second support position 2102, the second support member 220 is matched and fixed to the first support member 210 through the first fixing member 221 and the second fixing member 211.
It can be understood that the second support member 220 can be in the form of a plate, a rod, or a frame structure, etc. The second support member 220 can slide along the plate surface of the first support member 210 relative to the first support member 210, that is, the second support member 220 can slide horizontally and move to the second support position 2102. In this way, the installation of the water pump 500 is not affected by the compressor 400 or the upper and lower space. Other members can be arranged above or below the water pump 500, which is advantageous for the miniaturization design of the air-source heat pump air conditioner.
Specifically, when it is required to install the water pump 500, the water pump 500 is first fixed on the second support member 220, then the second support member 220 is pushed to slide along the plate surface of the first support member 210 so that the second support member 220 slides to the second support position 2102, and then the second fixing member 211 and the first fixing member 221 are matched and fixed.
In order to facilitate the maintenance or repair of the water pump 500, it is necessary for the water pump 500 to be detachable. Further, in this embodiment, the second fixing member 211 is detachably connected to the first fixing member 221. In this way, when it is necessary to disassemble the water pump 500, the first fixing member 221 and the second fixing member 211 are detached, and then the second support member 220 slides out of the second support position 2102 along the plate surface of the first support member 210 so that the water pump 500 can be removed.
The second fixing member 211 and the first fixing member 221 can be detachably connected in many ways, such as snap-fit connection, threaded connection, etc. The first fixing member 221 can be a part of the structure of the second support member 220 itself, or an additional member arranged on the second support member 220. The second fixing member 211 can also be a part of the structure of the first support member 210 itself, or an additional member arranged on the first support member 210.
Preferably, the first fixing member 221 and the second fixing member 211 can be connected to each other in the horizontal direction for easy installation from the side.
In an implementation, the air-source heat pump air conditioner further includes a first fastener for detachably connecting the first fixing member 221 with the second fixing member 211. Specifically, after the second support member 220 slides to the second support position 2102, the second fixing member 211 and the first fixing member 221 abut with each other in the horizontal direction. The first fastener is used to pass through the second fixing member 211 and the first fixing member 221 in the horizontal direction, so that the second fixing member 211 and the first fixing member 221 can be fixedly connected in a detachable manner.
In this embodiment, one end of the second support member 220 is provided with a first edgefold, which protrudes downward and forms the first fixing member 221. One end of a circumferential side wall of the first support member 210 itself forms the second fixing member 211. When the second support member 220 slides to the second support position 2102, the second fixing member 211 abuts with the first fixing member 221. Specifically, the first fastener is a screw, threaded holes 214 are correspondingly provided on the first fixing member 221 and the second fixing member 211, and the screw is inserted into the threaded holes 214.
Referring to FIG. 13, when the second support member 220 moves to the second support position 2102, the first fixing member 221 abuts with the second fixing member 211, that is, the first edgefold abuts with the circumferential side wall of the first support member 210. At this time, the second support member 220 can be fixed to the first support member 210 by passing the screw through the first edgefold and the circumferential side wall of the first support member 210 that abuts with the first edgefold.
Further, as shown in FIG. 10, in this embodiment, the first support member 210 is further provided with a first mating member 212, and the second support member 220 is provided with a second mating member 222. The second mating member 222 can cooperate with the first mating member 212 to enable the second support member 220 to slide along a certain direction (defined as a first direction) of the plate surface of the first support member 210, and to restrict the second support member 220 from moving in other directions, that is, directions perpendicular to the first direction. The other directions perpendicular to the first direction include a second direction in the horizontal direction, and the vertical direction.
When disassembling and installing the water pump 500, the second mating member 222 and the first mating member 212 can provide good guidance for the sliding of the second support member 220 on the first support member 210, allowing the second support member 220 to quickly move to the second support position 2102 in the first direction, which can not only position the installation position of the second support member 220, but also allows the threaded holes 214 on the first fixing member 221 and the second fixing member 211 to be positioned and aligned correspondingly when the second support member 220 slides to the second support position 2102, facilitating the connection of the first fixing member 221 and the second fixing member 211 using the screw.
There are various ways to fit the first mating member 212 with the second mating member 222, which can specifically be a guide rail mating with a sliding block. In this case, a guide rail can be arranged on the first support member 210, and a sliding block can be arranged on the second support member 220. The sliding block can be snap-fitted onto the guide rail and can move along the guide rail in the first direction. Specifically, in this embodiment, as shown in FIG. 10, the first mating member 212 is provided with a groove 213, and a groove opening of the groove 213 is oriented toward the second direction of the plate surface of the first support member 210, which is perpendicular to the first direction. The second mating member can be slidably inserted into the groove 213.
It can be understood that the first direction and the second direction are two directions perpendicular to each other in the horizontal plane. The groove opening of the groove 213 is arranged toward the second direction, so that upper and lower parts of the groove 213 can limit the movement of the second mating member in the up-and-down direction. At the same time, the groove 213 can also position the second mating member in the second direction, so that the second mating member can mostly slide only in the first direction.
Specifically, as shown in FIG. 11, the first mating member 212 includes a connection part 2121 and a restriction part 2122. The connection part 2121 is fixedly connected to the first support member 210, and one end of the connection part 2121 is folded upward to form a folded part 2123. The restriction part is connected to the folded part 2123, and is arranged in parallel to the connection part 2121. The folded part 2123, the restriction part 2122, and the connection part 2121 form the groove 213, and the groove opening of the groove 213 is arranged opposite to the folded part 2123. The restriction part and the connection part 2121 are not connected at the left end in the first direction, that is, the left end is a through opening. The second mating member 222 can be inserted into the groove 213 from the left end of the groove 213.
Specifically, the second mating member 222 can be a structure such as a downward transverse bending edge of the second support member 220.
In order to better position the installation of the second support member 220, as shown in FIG. 10, the number of the first mating member 212 is two, and the two first mating members 212 are spaced apart in the second direction. Two second mating members are correspondingly provided on the second support member 220. The groove openings of the two first mating members 212 can face each other. At this time, the two second mating members 222 can be arranged in the grooves 213 of the two first mating members 212 and face each other. Referring to FIG. 10, the groove openings of the two first mating members 212 can also face away from each other. At this time, the two second mating members 222 can be arranged in the grooves 213 of the two first mating members 212 and face away from each other. This embodiment will mainly be described using an example in which the groove openings of the two first mating members 212 face away from each other.
It can be understood that by providing two second mating members 222 and two first mating members 212, the two sides of the second support member 220 are restricted and guided, and the stability of the second support member 220 during sliding is higher. Especially in the solution where the groove openings of the two first mating members 212 face away from each other, the second mating member 222 can enter the first mating member 212 only from the through opening position at the left end of the groove 213 of the first mating member 212. During the sliding process of the second support member 220, under the action of the first mating members 212 and the second mating members 222 on both sides, the second support member 220 cannot move in the second direction or in the vertical direction, and can only slide in the first direction.
In the air-source heat pump air conditioner of this embodiment, a lower edge of the end of the second support member 220 that is not provided with the first fixing member 221 should be higher than a lower edge of the first fixing member 221, so that the first fixing member 221 can abut with the second fixing member 211 from the side. The specific process of installing the water pump 500 is as follows: the water pump 500 is installed on the second support member 220, with the end of the second support member 220 that is not provided with the first fixing member 221 facing forward and the end provided with the first fixing member 221 facing backward; then the second support member 220 is pushed to slide in the first direction; when the second support member 220 slides to the second support position 2102, the first fixing member 221 and the second fixing member 211 abut with each other, and then the first fixing member 221 and the second fixing member 211 are fixedly connected by passing a screw transversely into the threaded holes 214 of the first fixing member 221 and the second fixing member 211. When the second support member 220 slides to the second support position 2102, the end of the second support member 220 that is not provided with the first fixing member 221 is located on the upper side of the first support member 210.
When installing and disassembling the water pump 500, it is only required to remove the second support member 220. Due to the mating action between the first mating member 212 and the second mating member 222, only one screw is needed to fix the first fixing member 221 and the second fixing member 211 in actual operation, which can complete the fastening of the second support member 220. The operation is convenient and quick, and the screw can be assembled transversely to fasten the first fixing member 221 and the second fixing member 211. Compared with the installation method of inserting the screw from top to bottom or from bottom to top, the operation is more convenient. At the same time, the second support member 220 is installed and disassembled through transverse sliding, and the second mating member and the first mating member can be mated and pressed up and down tightly. When installing and disassembling the support member of the water pump 500, the second support member 220 only needs to slide horizontally, which improves the efficiency of disassembling and installing the water pump 500.
In this embodiment, the second chamber 205 is divided into upper and lower parts by the first support member 210. The lower part is used to arrange the water side heat exchanger 600, and the upper part is used to arrange the compressor 400 and the water pump 500, further improving the space utilization of the housing and facilitating the miniaturization design of the air-source heat pump air conditioner.
Optionally, the air-source heat pump air conditioner of this embodiment may further include a third support member 230, one end of which is connected to the bottom wall 206, and the other end of which is connected to the first support member 210. The third support member 230 can be in the form of a rod, a plate, or a frame structure.
In order to facilitate the installation and disassembly of the water side heat exchanger 600, the third support member 230 can be detachably connected to both the first support member 210 and the bottom wall 206.
Specifically, the third support member 230 can be connected to the bottom wall 206 through snap-fit or screws, and the third support member 230 can also be connected to the first support member 210 through snap-fit, screws, etc.
The third support member 230 can assist in supporting the first support member 210, so that the first support member 210 has higher support stability. Referring to FIG. 7, the third support member 230 can be separately and transversely installed and disassembled. After the third support member 230 is disassembled, the fixed position or support part on the second partition 202 can still support the first support member 210 and all the components above it. In other words, after the third support member 230 is disassembled, the first support member 210 can still stably support the compressor 400 and the water pump 500. With continued reference to FIG. 7, when it is necessary to disassemble the water side heat exchanger 600, the third support member 230 can be disassembled, and then the water side heat exchanger 600 can be disassembled separately. This operation will not affect other components, and can improve the efficiency of the installation, disassembly and maintenance of the water side heat exchanger 600.
Optionally, a gasket for supporting the water pump 500 can also be provided on the second support member 220 in this embodiment.
It should be noted that in this embodiment, there are certain gaps between the first chamber 204 and the second chamber 205. These gaps can be small gaps originally formed at the connection between the second partition 202 and the first partition 201 or the bottom wall 206, and they are not required to be made artificially. The gaps allow air to flow between the first chamber 204 and the second chamber 205. When the fan blade assembly 300 is turned on, the airflow in the second chamber 205 can flow toward the first chamber 204, which is advantageous for the heat dissipation of the compressor 400 and the water pump 500. In addition, the water pump 500 can also be provided with a cooling fan to quickly dissipate heat from the water pump 500. When the water pump 500 is provided with a cooling fan, a corresponding grille-like vent can be provided on the side wall of the housing 200 that corresponds to the second chamber 205 to facilitate air flow.
The water side heat exchanger 600 of the air-source heat pump air conditioner in this embodiment can be a double-pipe heat exchanger, which is spirally wound on the bottom wall 206 in the vertical direction, i.e., the up-and-down direction.
In some embodiments of this embodiment, as shown in FIGS. 14, 15, 16 and 17, a third fixing member 240 is provided on the bottom wall of the second chamber 205, i.e., at a position of the bottom wall 206 that corresponds to the second chamber 205, and the third fixing member 240 is used to fix the water side heat exchanger 600. Specifically, a fourth fixing member 250 is fixed on the water side heat exchanger 600, and the water side heat exchanger 600 can slide along the bottom wall 206 of the second chamber 205. After the water side heat exchanger 600 slides in place along the bottom wall 206 of the second chamber 205, the third fixing member 240 and the fourth fixing member 250 are mated and connected to fix the water side heat exchanger 600 on the bottom wall 206 of the second chamber 205.
With continued reference to FIGS. 14, 15, 16 and 17, in this embodiment, the third fixing member 240 includes a first limiting part 241 and a first installation part 242, both of which are fixed to the bottom wall 206. The first limiting part 241 is provided with a pressing groove, and a groove opening of the pressing groove is horizontally arranged. The fourth fixing member 250 includes a second limiting part 251 and a second installation part 252, both of which are fixedly connected to the water side heat exchanger 600. Under the sliding action of the water side heat exchanger 600 along the bottom wall 206 of the second chamber 205, the second limiting part 251 can be inserted into the pressing groove, and the second installation part 252 can be mated and fixedly connected to the first installation part 242.
When the second limiting part 251 is inserted into the pressing groove, the second limiting part 251 can be pressed tightly under the action of the first limiting part 241, so that the water side heat exchanger 600 cannot move vertically. The first installation part 242 and the second installation part 252 are fixedly connected, so that the water side heat exchanger 600 can be completely fixed on the bottom wall 206.
The numbers of the second limiting parts 251 and the first limiting parts 241 can each be multiple, with multiple first limiting parts 241 and multiple second limiting parts 251 being set in a one-to-one correspondence. The first installation part 242 and the second installation part 252 can be detachably connected by snap-fit, screwing and the like to facilitate the disassembly of the water side heat exchanger 600. Specifically, in this embodiment, the first installation part 242 and the second installation part 252 are fixedly connected by a second fastener, which may be a screw.
The numbers of the first installation part 242 and the second installation part 252 can each be one, or be multiple in a one-to-one correspondence. In a case where there are multiple (two or more) first limiting parts 241 mated with the second limiting parts 251 for pressing, only one first installation part 242 and one second installation part 252 may be provided, so that the water side heat exchanger 600 can be fixed by using one screw, making the operation convenient and quick.
The second limiting part 251 and the second installation part 252 of the fourth fixing member 250 can be separate structures or an integrated structure. Referring to FIG. 14, when the second limiting part 251 and the second installation part 252 of the fourth fixing member 250 are of an integrated structure, the second limiting part 251 and the second installation part 252 are configured into an L-shaped plate. The second installation part 252 is vertically arranged and fixedly connected to an inner side of the water side heat exchanger 600. The second limiting part 251 is arranged on a lower side of the second installation part 252 and is roughly horizontally arranged. The second installation part 252 can be fixedly connected to the first installation part 242 through a horizontally penetrating screw.
It should be noted that when the second limiting part 251 and the second installation part 252 of the fourth fixing member 250 are of an integrated structure, the number of the fourth fixing member 250 is multiple, and the second limiting part 251 of each fourth fixing member 250 can be mated with one first limiting part 241 for pressing and fixing. Among the multiple fourth fixing members 250, it is possible for only one second installation part 252 to be mated with the first installation part 242 and fastened through the second fastener.
Further, the first installation part 242 and the second installation part 252 can abut in the horizontal direction, so that the screw can penetrate into the first installation part 242 and the second installation part 252 in the horizontal direction, improving the convenience of assembly. When assembling or disassembling the water side heat exchanger of the air-source heat pump air conditioner in this embodiment, it is only required to disassemble the transverse screw and make the water side heat exchanger 600 slide horizontally, so that the water side heat exchanger 600 can be installed or disassembled quickly, avoiding the traditional disassembly method of inserting the screw from the top and improving work efficiency. Meanwhile, since the third support member 230 can be transversely disassembled and there is no influence on other components after disassembly, the water side heat exchanger 600 in the whole machine is easy to disassemble without affecting other components.
It should be noted that the first limiting part 241 and the first installation part 242 of the third fixing member 240 can be directly arranged on the bottom wall 206, or on a fixed plate 243, which is fixedly connected to the bottom wall 206.
The rear side wall, the left side wall, the front side wall, and the right side wall of the housing 200 in this embodiment can all be detachably arranged, so as to facilitate the disassembly of internal members adjacent to the side walls by disassembling the corresponding side walls. For example, as shown in FIGS. 1 and 2, the right side wall is detachably arranged, so that when it is necessary to disassemble the water pump 500, the compressor 400, or the water side heat exchanger 600, the right side wall can be removed from the housing 200, and then the water pump 500, the compressor 400, or the water side heat exchanger 600 can be disassembled, making the operation convenient and quick.
It should be noted that according to design requirements, it is also possible that only one, two, or three of the rear side wall, the left side wall, the front side wall, and the right side wall are detachably arranged.
In this embodiment, the water delivery pipeline connected to the water flow pipeline connected to the water side heat exchanger 600 includes a water inflow pipe 510 and a water outflow pipe 520. The water inflow pipe 510 is connected to a water inlet of the water flow pipeline, and the water outflow pipe 520 is connected to the water inlet of the water flow pipeline. The water pump 500 is arranged on the water outflow pipe 520.
In the air-source heat pump air conditioner of this embodiment, from water inflow to water outflow, the water inflow pipe 510, the water side heat exchanger 600, the water pump 500, and the water outflow pipe 520 are arranged in this order in the whole machine (the water outflow pipe 520 can be divided into a water pump water inflow pipe, a water pump water outflow pipe, and a whole machine water outflow pipe; correspondingly, from water inflow to water outflow, the water inflow pipe 510, the water side heat exchanger 600, the water pump water inflow pipe, the water pump 500, the water pump water outflow pipe, and the water outflow pipe 520 are arranged in this order in the whole machine). Water inflow and outflow connecting pipes of the water pump 500 can be soft connecting pipes for easy installation and disassembly.
Further, the right side wall or left side wall corresponding to the second chamber 205 is provided with a pipe inlet and a pipe outlet. The pipe inlet can be used to arrange the water inflow pipe 510 connected to the water side heat exchanger 600, and the pipe outlet can be used to arrange the water outflow pipe 520 connected to the water side heat exchanger 600.
Referring to FIG. 1 and FIG. 2, the second chamber 205 is formed on the right side of the housing 200. At this time, the right side wall corresponds to the second chamber 205, and the right side wall is provided with the pipe inlet and the pipe outlet. The water inflow pipe 510 is arranged in the pipe inlet, and the water outflow pipe 520 is arranged in the pipe outlet.
It can be understood that compared to the way in which the water inflow pipe 510 and the water outflow pipe 520 are arranged on the rear side of the housing 200, by arranging the water inflow pipe 510 and the water outflow pipe 520 on the left side wall or right side wall of the housing 200, the air-source heat pump air conditioner can be installed closer to the wall, and the operation space for connecting the water inflow pipe 510 and the water outflow pipe 520 to the circulating water pipe in the home is larger, making the operation more convenient.
It should be noted that as shown in FIGS. 1 and 2, the third support member 230 can be a part of the right side wall of the housing 200, which can save the consumables of the housing 200 and also facilitate the miniaturization arrangement of the housing 200. When the third support member 230 is a part of the right side wall, the pipe outlet is arranged on the third support member 230.
Further, the water inflow pipe 510 can be in clearance fit with the pipe inlet, so that the side wall where the pipe inlet is located can be separately disassembled without disassembling the water inflow pipe 510. Similarly, the water outflow pipe 520 can be in clearance fit with the pipe outlet, so that the side wall where the pipe outlet is located can be separately disassembled without disassembling the water outflow pipe 520.
Further, in the vertical direction, the position of a water inlet of the water inflow pipe 510 is higher than the highest position of the water flow pipeline of the water side heat exchanger 600 and the highest position of the water inflow pipe 510, and is located at the highest point of the water inflow pipe 510; the position of a drainage outlet of the water outflow pipe 520 is lower than the lowest position of the water flow pipeline and the lowest position of the water inflow pipe 510, and is located at the lowest point of the water outflow pipe 520. In this way, when the air-source heat pump air conditioner is not in use, all the water inside the air-source heat pump air conditioner can be discharged through the drainage outlet of the water outflow pipe 520, without water accumulation or easy air accumulation.
Further, there is no upward or downward recessed bending part on the water inflow pipe 510 and the water outflow pipe 520 of this embodiment, so as to avoid water and gas accumulation inside the water inflow pipe 510 and the water outflow pipe 520.
The electric control box 100 of this embodiment includes a box body 110 and an electric control assembly 120. The box body 110 can be a plastic box to reduce the weight of the box body. The box body 110 can have any shape, which can specifically be rectangular, cylindrical, and so on. The electric control assembly 120 is arranged inside the box body 110, including weak electricity elements for intelligent control of the air-source heat pump air conditioner and strong electricity elements for converting the strong electricity of the air-source heat pump air conditioner. In this embodiment, the electric control assembly 120 includes a filtering board 122, a main control board 123, and a module board 121. The main control board 123 is a circuit board used to control the air-source heat pump air conditioner; it is a weak electricity element and has functions such as signal acquisition, signal processing, and whole machine control, etc. The filtering board 122 can process the input and output strong electricity signals to prevent external power grid from interfering with the operation of the air-source heat pump air conditioner, and to prevent electrical signals output from the interior of the air-source heat pump air conditioner from interfering with the power grid. The module board 121 has functions of variable frequency drive control of the compressor 400 and AC/DC conversion control, etc.; it can achieve variable frequency operation of the air-source heat pump air conditioner, as well as AC/DC conversion.
The electric control assembly 120 inside the electric control box 100 generates a significant amount of heat during operation, so it is usually necessary to dissipate heat from the electric control box 100. In this embodiment, the housing 200 is provided with a whole machine air outlet, a whole machine air inlet, and a heat dissipation air inlet. The box body 110 is provided with a first air outlet 112 and a first air inlet 111. The first air outlet 112 is located near the air inflow end of the fan blade assembly 300 relative to the first air inlet 111, that is, the first air inlet 111 corresponds to the heat dissipation air inlet and is communicated with it. The first air outlet 112 faces the air inflow side of the fan blade assembly 300 and is communicated with it. The air outflow side of the fan blade assembly 300 is arranged corresponding to the whole machine air outlet and is communicated with it.
The whole machine air outlet and the whole machine air inlet are usually arranged opposite to each other. The whole machine air inlet is arranged corresponding to the air inflow end of the fan blade assembly 300, and is usually arranged on the rear side of the housing 200. The whole machine air outlet is arranged corresponding to the air outflow end of the fan blade assembly 300, and is usually arranged on the front side of the housing 200.
In the air-source heat pump air conditioner of this embodiment, when the fan blade assembly 300 is turned on, an airflow A formed by the air flows in from the heat dissipation air inlet, sequentially passes through the first air inlet 111, the box body 110, the first air outlet 112 and the fan blade assembly 300, and then flows out from the whole machine air outlet. Under the action of the fan blade assembly 300, the air can be promoted to quickly flow into the box body 110 from the first air inlet 111 and flow out from the first air outlet 112. The airflow A formed by the air quickly flows through the box body 110, so that the heat inside the box body 110 can be quickly taken away, improving the heat dissipation effect on the electric control box 100.
Further, the air-source heat pump air conditioner also includes a first water blocking assembly 260, which is arranged corresponding to the first air outlet 112 to block the water thrown out during the rotation of the fan blade assembly 300 from flowing into the first air outlet 112.
The first water blocking assembly 260 is correspondingly arranged at the first air outlet 112, and it can prevent water thrown out by the fan blade assembly 300 from entering the first air outlet 112 in rainy weather situations and the like, ensuring the waterproof performance of the electric control box 100.
In an implementation, referring to FIGS. 1, 18, 19, and 20, a through opening (defined as a first through opening 2012 for ease of description) is formed on the first partition 201. The electric control box 100 is arranged in the upper chamber 203, and the first air outlet 112 is arranged corresponding to the first through opening 2012. The first air outlet 112 is communicated with the first chamber 204 through the first through opening 2012. The fan blade assembly 300 is arranged in the first chamber 204, and the air inflow end is communicated with the first through opening 2012 and is arranged corresponding to the first through opening 2012.
The first water blocking assembly 260 in this embodiment is arranged corresponding to the first through opening 2012 or the first air outlet 112, that is, the first water blocking assembly 260 can be connected to the box body 110 of the electric control box 100 or to the first partition 201. A first water blocking plate 261 cooperates with the first through opening 2012 or the first air outlet 112 to allow the airflow A to pass through and prevent the fan blade assembly 300 from throwing rainwater into the electric control box 100.
In a specific implementation, the first water blocking assembly 260 is arranged on a bottom plate 116. Referring to FIG. 23, the first water blocking assembly 260 includes a first water blocking plate 261, which is arranged on an airflow path of the first air outlet 112 and intersects with the flow direction of the airflow flowing out through the first air outlet 112. A projection of the first air outlet 112 toward the first water blocking plate 261 falls onto an inner side of a circumferential edge of the first water blocking plate 261. The first through opening 2012 is arranged corresponding to the first air outlet 112, and the bottom plate 116 is abutted and fixed with the first partition 201. The circumferential edge of the first water blocking plate 261 includes a first edge part and a second edge part. The first water blocking plate 261 is connected to the bottom plate 116 through the first edge part, and an airflow channel is formed between the second edge part and the first partition 201. The airflow flowing out through the first air outlet 112 flows toward the fan blade assembly 300 through the airflow channel.
The first water blocking plate 261 intersects with the flow direction of the airflow flowing out through the first air outlet 112; specifically, the first water blocking plate 261 can be arranged opposite to the first air outlet 112. The projection of the first air outlet 112 toward the first water blocking plate 261 falls onto the inner side of the circumferential edge of the first water blocking plate 261, that is, the first water blocking plate 261 covers an area which the first air outlet 112 directly faces downward. Therefore, when the fan blade assembly 300 rotates, the water thrown out cannot enter the first air outlet 112.
It can be understood that the first water blocking plate 261 can be arranged above the first partition 201. At this time, the first water blocking plate 261 directly corresponds to the first air outlet 112 to form a stopper, preventing water from being thrown toward the first air inlet 111 when the fan blade assembly 300 rotates; the first water blocking plate 261 can also be arranged below the first through opening 2012, and correspondingly, the first water blocking plate 261 can achieve water blocking for the first through opening 2012 to prevent water from being thrown toward the first through opening 2012 when the fan blade assembly 300 rotates. This embodiment will mainly be described using an example in which the first water blocking plate 261 is arranged below the first partition 201.
The first edge part and the second edge part are both a part of the circumferential edge of the first water blocking plate 261, and can be continuously or interruptedly arranged. In this embodiment, as shown in FIG. 22, the first water blocking plate 261 is roughly rectangular in shape. The opposite left and right ends of the first water blocking plate 261 are the first edge parts, and the side edges extending in the left-and-right direction between the left and right ends are the second edge parts.
Further, in order to facilitate the cooperation of the first edge parts and the second edge parts with the bottom plate 116, a first flange 262 is provided on a side of the first edge part that faces the bottom plate 116, and the first flange 262 is fixedly connected to the bottom plate 116.
Optionally, specifically, the first edge part is provided with the first flange 262, while the second edge part is not provided with a flange. In this way, the first flange 262 protrudes from a plate surface of the first water blocking plate 261. By connecting the end of the first flange 262 that is away from the first water blocking plate 261 to the bottom plate 116, a gap is naturally formed between the second edge part and the first partition 201 due to the height difference since the second edge part is not provided with a flange.
Optionally, as shown in FIG. 22, specifically, it is also possible that the first edge part is provided with the first flange 262, and a side of the second edge part that faces the bottom plate 116 is provided with a second flange 263. In the direction perpendicular to the plate surface of the first water blocking plate 261, that is, in the vertical direction, the distance between the end of the first flange 262 that is away from the first water blocking plate 261 and the first water blocking plate 261 is a first distance, and the distance between the end of the second flange 263 that is away from the first water blocking plate 261 and the first water blocking plate 261 is a second distance, which is smaller than the first distance. In this way, the end of the first edge part that is away from the first water blocking plate 261 is higher, and the end of the second edge part that is away from the first water blocking plate 261 is lower. When the end of the first edge part that is away from the first water blocking plate 261 is connected to the bottom plate 116, a gap can be formed between the second edge part and the first partition 201 due to the height difference, which is also the airflow channel. In this implementation, the airflow from the first air outlet 112 flows through the first through opening 2012 toward the first water blocking plate 261, and then flows out along the gap (i.e., the airflow channel) between the second flange 263 and the first partition 201 to the air inflow side of the fan blade assembly 300.
Since the opening of the gap between the second flange 263 and the first partition 201 faces horizontally, the fan blade assembly 300 below can be prevented from throwing water into the electric control box 100 during rotation.
Further, in order to improve the waterproof performance, as shown in FIG. 7, the bottom plate 116 is provided with a first edgefold 2011 on the edge of the first through opening 2012. The first edgefold 2011 extends in the flow direction of the airflow flowing out through the first air outlet 112. The first edgefold 2011 is arranged on an inner side of the second flange 263, with a gap between the first edgefold 2011 and the first water blocking plate 261, a gap between the first edgefold 2011 and the second flange 263, and a gap between the second flange 263 and the first partition 201. The gap between the first edgefold 2011 and the first water blocking plate 261, the gap between the first edgefold 2011 and the second flange 263, and the gap between the second flange 263 and the first partition 201 form an airflow channel 2013. After passing through the first through opening 2012 from the first air outlet 112, the airflow A flows along the first edgefold 2011 toward the first water blocking plate 261, and then sequentially flows out through the gap between the first edgefold 2011 and the first water blocking plate 261, the gap between the first edgefold 2011 and the second flange 263, and the gap between the second flange 263 and the first partition 201, i.e., the airflow channel 2013. Due to the "maze" like communication sealing structure formed between the first edgefold 2011 and the second flange 263, a better water blocking effect can be achieved.
In order to facilitate the connection between the first flange 262 and the bottom plate 116, in an optional embodiment, one end of the first flange 262 that is away from the first water blocking plate 261 is provided with a connection flange 264 which protrudes outward away from the center of the first water blocking plate 261, and the connection flange 264 is fixedly connected to the bottom plate 116.
Referring to FIG. 22, the first flanges 262 on the left and right ends of the water blocking plate are respectively provided with connection flanges 264 which protrude outward and away from each other. The first flanges 262 on both ends are respectively fixedly connected to the bottom plate 116 at the corresponding ends. Specifically, the connection flanges 264 can be connected to the bottom plate 116 through screws, snap-fit, welding, and the like. As a preferred implementation, welding holes 265 can be provided for welding connection between the connection flanges 264 and the bottom plate 116, so that the connection flanges 264 are welded to the bottom plate 116 through the welding holes 265.
Referring to FIGS. 21 and 22, the first flange 262 on the left end and the first flange 262 on the right end are respectively lapped above a circumferential edge of the through opening, and the first water blocking plate 261 is arranged below the through opening. There are two welding holes 265 on the first flange 262 on the left end, and one welding hole 265 on the first flange 262 on the right end. By welding at the three welding holes 265 with solder, the first flange 262 and the second flange 263 can be fixed to the bottom plate 116 (i.e., to the first partition 201). The operation is convenient and the connection stability is high.
It should be noted that the first water blocking plate 261 in this embodiment is not limited to the above installation method, and it can also be connected to the first partition 201.
Further, in order to ensure the waterproof performance of the electric control box 100, the first air inlet 111 and/or the heat dissipation air inlet of the air-source heat pump air conditioner in this embodiment are correspondingly provided with a second water blocking assembly.
Specifically, in an implementation, the second water blocking assembly includes a second water blocking plate. The housing 200 can be provided with a second water blocking plate above the heat dissipation air inlet, and the second water blocking plate forms a shield above the heat dissipation air inlet to prevent rainwater from entering the heat dissipation air inlet, thereby protecting the electric control box 100. The box body 110 can also be provided with a second water blocking plate above the first air inlet 111, and the second water blocking plate forms a shield above the first air inlet 111 to prevent rainwater from entering the first air inlet 111, thereby protecting the electric control assembly 120 inside the electric control box 100.
Optionally, as shown in FIGS. 1 and 18, the first air inlet 111 can be arranged in a grille shape.
Optionally, the heat dissipation air inlet can also be arranged in a grille shape.
By arranging the first air inlet 111 and/or the heat dissipation air inlet in a grille shape, a certain waterproof effect can be achieved.
The electric control box 100 of this embodiment further includes a heat dissipation assembly 130, which includes an air guide cover 132 and a heat dissipation member 131. The air guide cover 132 is connected to the box body 110, and a ventilation channel is provided inside the air guide cover 132. The heat dissipation member 131 is arranged in the ventilation channel. The ventilation channel has a second air inlet 133 and a second air outlet 134. The second air outlet 134 is located near the air inflow end of the fan blade assembly 300 relative to the second air inlet 133, that is, the second air inlet 133 corresponds to the heat dissipation air inlet and is communicated with it, and the second air outlet 134 is communicated with the air inflow end of the fan blade assembly 300.
Specifically, as shown in FIGS. 20 and 21, the first partition 201 is also provided with a through opening (defined as a second through opening 2014 for ease of description) corresponding to the second air outlet 134, and the second air outlet 134 can be communicated with the first chamber 204 through the second through opening 2014.
As shown in FIG. 21, a water blocking assembly can also be arranged on the second through opening 2014. The water blocking assembly can adopt the same structure as the first water blocking assembly 260, or other structures such as a grille structure.
The heat dissipation assembly 130 is used for targeted heat dissipation of an electrical assembly. It can be placed inside the box body 110, for example, on one side of the electrical assembly, or on the outside of the box body 110 and corresponding to the electrical assembly. When the heat dissipation assembly 130 is arranged on the outside of the box body 110, the heat emitted by the electrical assembly is transferred to the box body 110, and the box body 110 further transfers the heat to the heat dissipation assembly 130. The heat dissipation assembly 130 cools down the box body 110 and ultimately achieves cooling of the electrical assembly.
After the air-source heat pump air conditioner provided in this embodiment is turned on, as shown in FIG. 2, the fan blade assembly 300 forms a negative pressure on the air inflow side, and the airflow A from the second air outlet 134 and the first air outlet 112 flows toward the through openings (including the first through opening 2012 and the second through opening 2014). Correspondingly, the first air inlet 111, the space inside the box body 110, and the first air outlet 112 form a heat dissipation path, which can quickly dissipate the heat inside the box body 110 and facilitate the heat dissipation of the electrical assembly inside the box body 110. The heat dissipation assembly 130 is arranged specifically for the electrical assembly, with the second air inlet 133, the heat dissipation channel and the second air outlet 134 forming another heat dissipation path, which can enhance the heat dissipation of the electrical assembly in a targeted manner.
The air-source heat pump air conditioner of this embodiment utilizes its own fan blade assembly 300 to generate a driving power of the airflow for dissipating heat from the electric control box 100, without the need for other driving sources. The structure is simple, and the double heat dissipation paths are used to effectively dissipate heat from the electrical assembly, improving the heat dissipation effect on the electric control box 100.
Optionally, the heat dissipation assembly 130 includes the air guide cover 132 and the heat dissipation member 131. The air guide cover 132 is correspondingly connected at the position where the electrical assembly is arranged in the box body 110, and a ventilation channel is formed inside the air guide cover 132. The heat dissipation member 131 is arranged inside the ventilation channel.
The second air inlet 133 and the second air outlet 134 of the ventilation channel of the air guide cover 132 can be arranged according to requirements. Usually, in order to ensure the heat dissipation effect of the heat dissipation member 131, the second air inlet 133 and the second air outlet 134 can be formed at two opposite ends of the air guide cover 132 respectively. That is, the second air inlet 133 and the second air outlet 134 are located at two opposite ends of the heat dissipation member 131 respectively, so that the airflow entering the second air outlet 134 from the second air inlet 133 can flow through the entire part of the heat dissipation member 131, enabling the heat dissipation member 131 to have a good heat dissipation effect.
The materials of the air guide cover 132 and the heat dissipation member 131 are thermally conductive materials, such as steel, so as to facilitate heat conduction and dissipation. The shape of the air guide cover 132 can be set as needed, and specifically can be cylindrical, rectangular, etc. The heat dissipation member 131 specifically can be a heat-conducting fin structure, a plate-shaped structure, etc. The heat dissipation member 131 can be fixed on a side of the air guide cover 132 that faces the box body 110.
According to some embodiments of the present disclosure, in an implementation, the box body 110 includes the bottom plate 116, a top plate 115, and side plates connected between the bottom plate 116 and the top plate 115. The bottom plate 116, the top plate 115, and the side plate together enclose an accommodation space, and the electrical assembly is arranged inside the accommodation space.
Referring to FIGS. 1, 18, and 19, in a specific implementation, the box body 110 is roughly rectangular in shape. The bottom plate 116 and the top plate 115 are arranged in parallel and opposite to each other, and the side plates are connected between the bottom plate 116 and the top plate 115. The bottom plate 116, the top plate 115, and the side plates together enclose a rectangular accommodation space, and the electrical assembly is arranged inside the accommodation space.
Specifically, the electrical assembly can be directly fixed on an inner side surface of the side plate, an inner side surface of the bottom plate 116, and/or an inner side surface of the top plate 115, or suspended and fixed inside the electric control box 100 through a support structure. The first air inlet 111 and the second air inlet 133 can be reasonably arranged on the bottom plate 116, the top plate 115, or the side plates according to the position of the fan blade assembly 300.
It should be noted that in order to ensure good heat dissipation effect on the electric control box 100, it is not appropriate for the first air inlet 111 and the first air outlet 112 to be arranged on plates having the same direction. In this implementation, the bottom plate 116 corresponds to the air inflow side of the fan blade assembly 300, so the first air outlet 112 is arranged on the bottom plate 116. At this time, the first air inlet 111 can be arranged on the top plate 115 or the side plate, or both the top plate 115 and the side plate are provided with the first air inlet 111.
In the electric control box 100 of this embodiment, the electrical assembly is arranged inside the accommodation space, leaving only the first air inlet 111 and the first air outlet 112 on the box body 110. The electric control box 100 has strong waterproof, dustproof, and fireproof capabilities.
According to some embodiments of the present disclosure, optionally, the electrical assembly is partially or entirely attached and fixed to the inner side surface of the box body 110, and the heat dissipation assembly 130 is arranged on the outer side surface of the box body 110 at a position corresponding to the electrical assembly.
Referring to FIG. 19, the module board 121 and the heat dissipation assembly 130 are arranged on the same plate surface of the box body 110, and are respectively located on the inner and outer sides of the plate surface.
By arranging the heat dissipation assembly 130 on the outer side surface of the box body 110 at a position corresponding to the module board 121, on one hand, heat of the electrical assembly can be well dissipated, and on the other hand, the heat dissipation assembly 130 does not occupy the internal space of the electrical assembly, which can reduce the volume of the box body 110 and facilitate the arrangement of the electrical assembly inside the box body 110.
It should be noted that the heat dissipation assembly 130 can be arranged for all the electrical assemblies, that is, the outer sides of the plate surfaces corresponding to the electrical assemblies are all covered with the heat dissipation assembly 130; or the heat dissipation assembly 130 is arranged only for some electrical assemblies. For example, the heat dissipation assembly 130 only corresponds to the arrangement positions of the filtering board 122 and the module board 121, or the heat dissipation assembly 130 only corresponds to the arrangement position of the module board 121, etc. Due to the low heat generation amount of the main control board 123 and the filtering board 122 themselves, good cooling effect can be achieved by the airflow passing through the first air inlet 111 and the first air outlet 112. However, the module board 121 has a large heat generation amount and therefore requires strong heat dissipation. Therefore, in this embodiment, the heat dissipation assembly 130 is arranged corresponding to the arrangement position of the module board 121.
Further, in a specific arrangement structure of this embodiment, the electrical assemblies and the heat dissipation assembly 130 are respectively arranged on the inner and outer side surfaces of the side plates.
The module board 121, the main control board 123, and the filtering board 122 are all arranged on the inner side surfaces of the side plates, and the heat dissipation assembly 130 can be arranged on the outer side surface of the box body 110 at a position corresponding to the module board 121.
Specifically, as shown in FIG. 18, the air guide cover 132 is attached and fixed to the position where the module board 121 is arranged on a first sub plate 1171. An upper end of the air guide cover 132 forms the second air inlet 133, and a lower end of the air guide cover 132 forms the second air outlet 134. The air guide cover 132 forms a ventilation channel that penetrates in the up-and-down direction between the second air inlet 133 and the second air outlet 134, and the heat dissipation member 131 is arranged in the ventilation channel.
The side plates include a second sub plate 1172 and a first sub plate 1171 that are sequentially arranged in a circumferential direction of the top plate 115 and connected to each other. The second sub plate 1172 and the first sub plate 1171 are arranged at a right angle. The module board 121, the main control board 123, and the filtering board 122 are all arranged on the first sub plate 1171, or two of the module board 121, the main control board 123, and the filtering board 122 are arranged on the first sub plate 1171, and the other of the three is arranged on the second sub plate 1172.
The second sub plate 1172 and the first sub plate 1171 are adjacent side plates, and are two plates arranged at a right angle, that is, the box body 110 should have two adjacent side plates arranged at a right angle. In this embodiment, the box body 110 is roughly rectangular in shape, and correspondingly, the second sub plate 1172 and the first sub plate 1171 can be any two adjacent side plates among the four.
Several specific arrangements of the module board 121, the main control board 123, and the filtering board 122 will be given below.
Referring to FIG. 19, in a first arrangement, the module board 121, the main control board 123, and the filtering board 122 are all arranged on the first sub plate 1171. The module board 121 and the filtering board 122 are sequentially arranged in a third direction of the side plate, and the main control board 123 is stacked on top of the filtering board 122. Specifically, the electric control box 100 further includes a fixed bracket 1175, which is connected to the first sub plate 1171. The main control board 123 is arranged on the fixed bracket 1175, and an installation gap is provided between the fixed bracket 1175 and the first sub plate 1171. The filtering board 122 is arranged in the installation gap and connected to the first sub plate 1171.
Further, in order to facilitate the separate disassembly and maintenance of the filtering board 122 without being affected by the main control board 123, the filtering board 122 can be designed as a pull-out structure, so that the filtering board 122 can slide relative to the first sub plate 1171 in the direction from the bottom plate 116 to the top plate 115. Specifically, two sliding grooves can be arranged in the first sub plate 1171 in the direction from the bottom plate 116 to the top plate 115, and the filtering board 122 is slidably arranged in the two sliding grooves. The sliding grooves and the filtering board 122 cooperate with each other, so that the filtering board 122 only has degree of freedom in the connection direction between the bottom plate 116 and the top plate 115.
It should be noted that when the module board 121, the main control board 123, and the filtering board 122 are all arranged on the first sub plate 1171, the length of the first sub plate 1171 is usually larger than that of the second sub plate 1172.
It can be understood that the module board 121 is independently arranged on the first sub plate 1171, which is advantageous for quickly heat dissipation of the module board 121 having a larger heat generation amount. The stacking arrangement of the main control board 123 and the filtering board 122 can reduce the volume of the box body 110, which is advantageous for the miniaturization design of the electric control box 100. Moreover, the filtering board 122, the module board 121, and the main control board 123 are all arranged on the first sub plate 1171 and can be arranged in parallel. When assembling the electric control box 100, the operator can place the box body 110 in one state to complete the assembly of the three boards without flipping the box body 110 back and forth to change its orientation. The assembly efficiency of the electric control box 100 is high and the labor intensity of manual labor is reduced.
It should be noted that the filtering board 122, the module board 121, and the main control board 123 can also be arranged together on the first sub plate 1171 in other ways. For example, the filtering board 122, the module board 121, and the main control board 123 are sequentially arranged in parallel in the length direction of the first sub plate 1171. For another example, the filtering board 122 and the module board 121 are arranged in the length direction of the first sub plate 1171, while the filtering board 122 and the main control board 123 are arranged in the width direction of the first sub plate 1171.
In the first arrangement, in order to achieve a better heat dissipation effect on the filtering board 122, the module board 121, and the main control board 123, as shown in FIGS. 18 and 19, the first air inlets 111 are arranged on the second sub plate 1172 and a third sub plate 1173 opposite to the second sub plate 1172. The first air inlet 111 on the second sub plate 1172 and the first air inlet 111 on the third sub plate 1173 are both located near the first sub plate 1171, and the first air outlet 112 is arranged near the module board 121 having a larger heat generation amount.
In actual arrangement, the first sub plate 1171 of the box body 110 can be placed on the rear side, and correspondingly, the second sub plate 1172 and the third sub plate 1173 are placed on the left and right sides. In this way, the air inlet of the housing 200 of the air-source heat pump air conditioner that corresponds to the position of the first air inlet 111 can be arranged on the rear side of the housing 200, which is more beautiful and advantageous for the arrangement of other members.
In a second arrangement, the filtering board 122 and the module board 121 can be arranged on the first sub plate 1171, and the main control board 123 can be arranged on the second sub plate 1172, with the main control board 123 in a position that does not affect the first air inlet 111. The other arrangements are the same as the first arrangement. This arrangement allows the main control board 123 to be directly connected to the second sub plate 1172 without the need for an additional fixed bracket 1175, making the structure relatively simple.
Referring to FIGS. 24, 25, and 26, in a third arrangement, the main control board 123 and the filtering board 122 are sequentially arranged on the first sub plate 1171 in the length direction of the first sub plate 1171, and the module board 121 is arranged on the second sub plate 1172. The first air inlets 111 are arranged on the first sub plate 1171 and a fourth sub plate 1174 opposite to the first sub plate 1171. The first air inlet 111 on the first sub plate 1171 is in a position that does not affect the arrangement of the main control board 123 and the filtering board 122.
Since the module board 121 is usually larger, in order not to excessively increase the volume of the box body 110, one end of the bottom plate 116 that corresponds to the module board 121, i.e., the end connected to the second sub plate 1172, is recessed toward a side that is away from the top plate 115 to form a recess part 1161, and the lower end of the module board 121 is inserted into the recess part 1161. In this way, the recess part 1161 is formed with a side surface part 1162 parallel to the side plate, and the first air outlet 112 is correspondingly provided on the side surface part 1162.
It should be noted that in other arrangements of the filtering board 122, the module board 121 and the main control board 123, the bottom plate 116 can also be formed with a recess part 1161 for a certain component to facilitate the installation of the component into the box body 110 having a smaller length.
It can be understood that arranging the first air outlet 112 on the side surface part 1162 of the recess part 1161 can prevent condensate water or rainwater on the fan blade assembly 300 from being thrown into the box body 110 through the first air outlet 112 when the fan blade assembly 300 rotates. This can provide a certain waterproof effect and avoid damage to the electrical assembly inside the box body 110.
It should be noted that the recess part 1161 of this embodiment is preferably arranged corresponding to a rear end in the rotational direction of the fan blade assembly 300. For example, as shown in FIG. 24, when the fan blade assembly 300 rotates clockwise during normal operation, the recess part 1161 is arranged on the left side in this time. In this way, if water is thrown during the rotation of the fan blade assembly 300, the water flow will flow clockwise to the right and is not easy to enter the first air inlet 111 of the recess part 1161. Of course, when the fan blade assembly 300 is not working, it may also rotate in the opposite direction due to external wind blowing. In this situation, in order to prevent water from entering the first air inlet 111, the first water blocking assembly 260 can still be arranged on the recess part 1161 corresponding to the first air inlet 111 to prevent the fan blade assembly 300 from throwing water toward the first air inlet 111 through the action of the first water blocking assembly 260.
Optionally, in order to facilitate the installation and disassembly of the module board 121, it can be designed as a pull-out installation structure. Especially for the third arrangement in which the lower end of the module board 121 is inserted into the recess part 1161, the pull-out method can improve the installation efficiency of the module board 121. Specifically, a sliding limit part is provided on the second sub plate 1172, and the module board 121 is connected to the sliding limit part. The sliding limit part restricts the module board 121 from moving in a direction perpendicular to the direction from the bottom plate 116 to the top plate 115, and enables the module board 121 to slide in the direction from the top plate 115 to the bottom plate 116.
Specifically, the sliding limit part includes two sliding grooves, each of which extends in the vertical direction. The two sides of the module board 121 are respectively snap-fitted in the two sliding grooves, and the module board 121 can slide vertically in the sliding grooves. The movements of the module board 121 in the left-and-right direction as well as in the front-and-rear direction are limited by the sliding grooves, so the module board 121 only has the degree of freedom to slide in the vertical direction. When the module board 121 is installed in place, the bottom wall of the recess part 1161 supports the module board 121 and restricts it from further moving downward, so that the module board 121 can be only pulled upward and taken out, making the operation easy.
It should be noted that as shown in FIG. 24, in a case where the box body 110 is provided with the recess part 1161, the first partition 201 is provided with an installation hole corresponding to the recess part 1161, and the recess part 1161 passes through the installation hole and is located inside the first chamber 204. Due to the correspondence between the recess part 1161 and the installation hole, when installing the box body 110 onto the first partition 201, the recess part 1161 and the installation hole can cooperate to serve as guiding and positioning members for the installation process of the electric control box 100.
Optionally, the box body 110 includes a first part 113 and a second part 114. The first part 113 and the second part 114 enclose to form the box body 110, and the first part 113 and the second part 114 are detachably connected.
Specifically, in an implementation, referring to FIGS. 18, 25, and 26, the first part 113 includes the top plate 115 and some of the side plates, while the second part 114 includes the bottom plate 116 and some of the side plates. The side plates forming the second sub plate 1172 and the first sub plate 1171 are located on the same part. In this embodiment, the second sub plate 1172 and the first sub plate 1171 are located on the second part 114, so that the operator can operate on the second part 114 to complete the installation of the filtering board 122, the module board 121, and the main control board 123.
Due to the detachable connection between the first part 113 and the second part 114, only the first part 113 or the second part 114 needs to be disassembled or installed during installation or disassembly, which improves the efficiency of disassembling and installing the electric control box 100.
The electric control box 100 of this embodiment further includes a terminal block 124, which can also be arranged on the inner side surface of the bottom wall 206. The terminal block 124 is used to connect wire harnesses connected to the filtering board 122, the main control board 123 and the module board 121, etc.
Further, as shown in FIGS. 29, 30 and 31, a heating tube 800 is arranged inside the first chamber 204. The heating tube 800 can specifically be an electric heating tube.
The drainage outlet and the electric heating tube are arranged inside the first chamber 204. The drainage outlet is arranged on the bottom wall 206 of the first chamber 204, and the electric heating tube can be arranged close to the drainage outlet. The drainage outlet is used to discharge rainwater in the first chamber 204 or condensate water dripping from the air side heat exchanger 310. When it is relatively cold in winter, the drainage outlet in the first chamber 204 is often blocked due to ice formation. The electric heating tube is arranged in the first chamber 204 to heat the first chamber 204 and melt the ice at the drainage outlet, ensuring the drainage performance of the drainage outlet in winter.
Specifically, the electric heating tube can be installed on the bottom wall 206 of the first chamber 204 or on the side wall at a position near the bottom wall 206 through a buckle 820. Two ends of the electric heating tube are wiring terminals 810, which are used to connect wires. The two ends of the heating tube 800 are tilted upward relative to the middle of the heating tube 800, that is, the wiring terminals 810 of the electric heating tube are tilted upward to prevent the wiring terminals 810 of the electric heating tube from contacting the accumulated water in the first chamber 204, thereby improving the safety performance of the electric heating tube.
Referring to FIG. 1, in the air-source heat pump air conditioner of this embodiment, when the electric control box 100 is working, the airflow A formed by air enters the upper chamber 203 through the heat dissipation air inlet arranged in the upper chamber 203, enters the electric control box 100 through the first air inlet 111 of the electric control box 100, passes through the electrical assembly to take away heat, flows into the negative-pressure first chamber 204 through the first air outlet 112 and the first through opening 2012 of the first partition 201, and finally discharges the heat; at the same time, the heat dissipation assembly 130 located at the rear of the module board 121 dissipates heat from the electric control box 100, so that the electric control box 100 can have good heat dissipation performance. Meanwhile, the waterproof, fireproof, and dustproof performances of the electric control box 100 are significantly improved.
The embodiment of a second aspect of the present application provides an air-source heat pump air conditioner, which differs from the embodiment of the first aspect of the present application only in the electric control box 100. Specifically, the heat dissipation assembly of the electric control box 100 is different from that of the embodiment of the first aspect of the present application.
Referring to FIGS. 27 and 28, the heat dissipation assembly of the electric control box 100 in this embodiment includes a refrigerant radiator and a refrigerant connecting pipe 150. The refrigerant radiator 140 is connected to the box body 110, and can exchange heat with the box body 110 and the air inside the box body 110 to lower the temperature inside the box body 110.
The refrigerant radiator 140 can create a low-temperature environment, thereby forming a temperature difference from the environment inside the box body 110. The heat inside the box body 110 can be transferred to the refrigerant radiator 140, thereby cooling the electric control assembly 120 inside the box body 110. Specifically, the refrigerant radiator 140 is usually provided with a refrigerant flow channel. A low-temperature environment of the refrigerant radiator 140 is formed by introducing flowing refrigerant into the refrigerant flow channel. At the same time, the heat inside the box body 110 is taken away by the flow of refrigerant, thereby quickly cooling the environment inside the box body 110. The refrigerant radiator 140 can utilize the refrigerant in the refrigerant circuit of the air-source heat pump air conditioner itself so that the refrigerant radiator 140 can constantly have a low-temperature environment; the refrigerant radiator 140 can also utilize an additional refrigerant cooling circuit to achieve the low-temperature environment of the refrigerant radiator 140.
Further, a flow disturbing assembly can also be arranged inside the box body 110, and the flow disturbing assembly 160 is used to disturb the air inside the box body 110 to promote the flow of air inside the box body 110.
Through the cooperation of the flow disturbing assembly 160 and the refrigerant radiator 140, heat dissipation of the electric control box 100 can be quickly carried out, so that the electric control assembly 120 can be arranged inside the relatively sealed box body 110. The box body 110 can provide protection for the electric control assembly 120, and the waterproof, dustproof, and fireproof capabilities of the electric control assembly 120 are significantly enhanced.
The box body 110 of the electric control box 100 in this embodiment may also include a first part and a second part. The first part and the second part enclose to form the box body 110, and the first part and the second part are detachably and sealedly connected.
Specifically, as shown in FIGS. 27 and 28, in an implementation, the box body 110 is roughly rectangular in shape, including a top plate 115, a bottom plate 116, and side plates 117 connected between the top plate 115 and the bottom plate 116. The bottom plate 116 and the side plates 117 can be an integrally formed non-detachable structure; correspondingly, the bottom plate 116 and the side plates 117 form the second part, and the top plate 115 forms the first part. The top plate 115 and the side plates 117 are detachably and sealedly connected.
A sealing ring (which can be a rubber sealing ring) or sponge can be specifically provided between the top plate 115 and the side plates 117 to achieve a sealed connection between the top plate 115 and the side plates 117 through the sealing ring or sponge. Specifically, the detachable connection between the top plate 115 and the side plates 117 can be bolt connection, snap-fit connection, etc.
It should be noted that the electric control assembly 120 can be installed on the first part or on the second part. In the embodiment in which the bottom plate 116 cooperates with the side plates 117 to form the second part, the electric control assembly 120 is installed on the second part. The division of the first part and the second part is not limited to the above way. For example, it is also possible that the top plate 115 and some of the side plates 117 form the first part, and the bottom plate 116 and the others of the side plates 117 form the second part.
Optionally, the refrigerant circuit of the air-source heat pump air conditioner is communicated with the refrigerant flow channel of the refrigerant radiator 140 through the refrigerant connecting pipe 150, so that the refrigerant in the refrigerant circuit can flow through the refrigerant flow channel.
Specifically, in an implementation, the refrigerant flow channel of the refrigerant radiator 140 is connected in series with the refrigerant circuit of the air-source heat pump air conditioner. The refrigerant channel is connected in series between the air side heat exchanger 310 and the water side heat exchanger 600 through the refrigerant connecting pipe 150, and the refrigerant flowing to the refrigerant radiator 140 should be low-temperature refrigerant. Taking the heating process as an example, specifically, the refrigerant channel of the refrigerant radiator 140 has an inlet and an outlet. The inlet of the refrigerant channel is communicated with an outlet of the refrigerant pipeline of the water side heat exchanger 600 through the refrigerant connecting pipe 150, and the outlet of the refrigerant channel is communicated with an inlet of the air side heat exchanger 310 through the refrigerant connecting pipe 150. After the refrigerant that has completed heat exchange with the water flow in the water flow pipeline flows out of the water side heat exchanger 600, it first flows into the refrigerant circuit of the refrigerant radiator 140, and then exchanges heat with the electric control box 100 before flowing into the air side heat exchanger 310.
It should be noted that in actual arrangement, the refrigerant flow channel of the refrigerant radiator 140 can be connected between the expansion valve and the air side heat exchanger 310, or the refrigerant flow channel of the refrigerant radiator 140 can be connected between the refrigerant pipeline of the water side heat exchanger 600 and the expansion valve. During the cooling process, the inlet and the outlet of the refrigerant radiator 140 can be interchanged so that the refrigerant flowing to the refrigerant radiator 140 is always low-temperature refrigerant.
By connecting the refrigerant flow channel in series with the refrigerant circuit of the air-source heat pump air conditioner, the characteristics of the refrigerant in the air-source heat pump air conditioner can be reasonably utilized without the need for an additional refrigerant cooling circuit. The structure is simple and the cost is not increased.
It should be emphasized that the refrigerant in the refrigerant circuit can partially pass through the refrigerant radiator 140. At this time, the refrigerant flow channel of the refrigerant radiator 140 is communicated between the air side heat exchanger 310 and the water side heat exchanger 600 through the refrigerant connecting pipe 150. At the same time, the refrigerant pipeline is still provided between the air side heat exchanger 310 and the water side heat exchanger 600. The refrigerant in the refrigerant circuit can also completely pass through the refrigerant radiator 140. At this time, the refrigerant between the air side heat exchanger 310 and the water side heat exchanger 600 is only communicated through the refrigerant flow channel of the refrigerant radiator 140.
Further, the refrigerant radiator 140 of this embodiment may also include a throttling component, which is arranged on the refrigerant connecting pipe 150; specifically, it can be arranged on the refrigerant connecting pipe 150 connected to the inlet of the refrigerant flow channel.
The refrigerant radiator 140 of the electric control box 100 in this embodiment can have various structural forms. Optionally, in an embodiment, the refrigerant radiator 140 includes a heat exchange plate with refrigerant flow channel, and the heat exchange plate is used for attaching and connecting with the box body 110. In this embodiment, the refrigerant radiator 140 includes a fin structure connected to the box body 110, and a refrigerant flow channel is provided inside the fin structure.
The refrigerant radiator 140 can be arranged inside or outside the box body 110. In this embodiment, both the refrigerant radiator 140 and the electric control assembly 120 are installed inside the box body 110. Specifically, the box body 110 is internally provided with an installation plate 118, and the electric control assembly 120 and the refrigerant radiator 140 are located on both sides of a plate surface of the installation plate 118 respectively. That is, the refrigerant radiator 140 is arranged on one side of the plate surface of the installation plate 118, and the electric control assembly 120 is arranged on the other side of the plate surface of the installation plate 118. The refrigerant radiator 140 is arranged on the outer side surface of the box body 110 and corresponds to the position where the electric control assembly 120 is located.
It can be understood that the refrigerant radiator 140 and the electric control assembly 120 are arranged on the same installation plate 118, which is advantageous for the refrigerant radiator 140 to directly dissipate heat from the electric control assembly 120. Further, the refrigerant radiator 140 can be arranged corresponding to the position of the electric control assembly 120, so that some of the heat generated by the electric control assembly 120 can be directly transferred to the refrigerant radiator 140 through the installation plate 118, thereby improving the heat dissipation effect of the refrigerant radiator 140 on the electric control assembly 120.
It should be noted that the electric control assembly 120 is not limited to being arranged on the installation plate 118. The electric control assembly 120 can also be directly arranged on other side walls of the box body 110. At the same time, the filtering board 122, the module board 121, and the main control board 123 are also not limited to being arranged on the same plate surface. The refrigerant radiator 140 can be arranged for all the electric control assemblies 120, that is, the outer sides of the plate surfaces corresponding to the electric control assemblies 120 are all covered with the refrigerant radiator 140, or the refrigerant radiator 140 can be arranged only for some electric control assemblies 120. For example, the refrigerant radiator 140 only corresponds to the arrangement positions of the filtering board 122 and the module board 121, or the refrigerant radiator 140 only corresponds to the arrangement position of the module board 121, etc. Since the heat generation amount of the main control board 123 and the filtering board 122 themselves is low, while the heat generation amount of the module board 121 is relatively large and it requires strong heat dissipation, in this embodiment, the refrigerant radiator 140 is arranged at least corresponding to the arrangement position of the module board 121.
Referring to FIGS. 27 and 28, corresponding to the form of the box body 110 including the bottom plate 116, the top plate 115 and the side plates 117, the electric control assembly 120 of this embodiment can be arranged corresponding to the bottom plate 116. In an arrangement, the installation plate 118 is arranged between the bottom plate 116 and the top plate 115, and is located close to the bottom plate 116. The surrounding edges of the installation plate 118 are fixedly connected to the inner side surfaces of the side plates 117. An accommodation space is formed between the installation plate 118 and the top plate 115, and the electric control assemblies 120 are arranged in this accommodation space and installed on a side surface of the installation plate 118 that faces the top plate 115 (i.e., the side surface facing the accommodation space). An accommodation gap is formed between the installation plate 118 and the top plate 115; the refrigerant radiator 140 is arranged in this accommodation gap, and is abutted with a side surface of the installation plate 118 that faces the bottom plate 116.
Referring to FIG. 28, in an embodiment, a flow disturbing assembly 160 is arranged on the inner side surface of the side plate 117. At this time, the flow disturbing assembly 160 should be located between the installation plate 118 and the top plate 115 to facilitate the flow disturbing assembly 160 to disturb the air in the environment where the electric control assemblies 120 are located. In another implementation, the flow disturbing assembly 160 is arranged on the inner side surface of the top plate 115.
It can be understood that arranging the flow disturbing assembly 160 on the inner side surface of the side plate 117 or on the inner side surface of the top plate 115 can avoid mutual interference between the fan and the electric control assemblies 120.
It should be noted that in a case where there is sufficient space in the box body 110, the flow disturbing assembly 160 can also be arranged on the inner side surface of the installation plate 118.
The electric control assembly 120 of this embodiment can be a fan. Referring to FIGS. 27 and 28, the fan is arranged on the inner side surface of the side plate 117 of the box body 110. One side of the fan can suck air from the box body 110, while the other side can blow air into the box body 110, thereby disturbing the air inside the box body 110.
Further, the box body 110 of the electric control box 100 in this embodiment is further provided with wiring holes, which are used for passing wire harnesses such as electric wires and signal wires connected to the electric control assembly 120. An elastic sealing member is arranged on the wiring hole, which is sealed on the wiring hole. A wire passing hole is arranged on the elastic sealing member, and the elastic sealing member can adaptively tighten the wire harness passing through the wire passing hole through its own elasticity.
Specifically, the elastic sealing member can be a rubber ring made of rubber material, which is provided with the wire passing hole. A circumferential edge of the rubber ring is provided with a fixing groove, and the fixing groove of the rubber ring is snap-fitted on a hole wall of the wire passing hole for interference fit. The wire passing hole of the rubber ring can adapt to the wire harness due to the elasticity of the rubber ring, and bind and fix the wire harness, so that the wire passing hole has a certain degree of sealing to prevent dust, water and the like from entering the box body 110, improving the waterproof and dustproof capabilities of the electric control assembly 120.
It should be noted that the box body 110 of the electric control box 100 in this embodiment can be sealed. At this time, there is no need to arrange the first air inlet 111 and the first air outlet 112 on the electric control box 100. Correspondingly, the heat dissipation air inlet can be arranged directly corresponding to the first chamber 204, without necessarily arranging it corresponding to the upper chamber 203. Of course, the box body 110 of this embodiment can also be combined with the heat dissipation method of arranging the first air inlet 111 and the first air outlet 112 on the box body 110 of the embodiment of the first aspect. The flow disturbing assembly 160 in this embodiment can also be applied to the electric control box 100 of the embodiment of the first aspect. In addition, the refrigerant radiator of this embodiment can be combined with the heat dissipation assembly of the embodiment of the first aspect to further improve the heat dissipation effect on the electric control box 100.
It should also be noted that the descriptions of the embodiment of the first aspect and the embodiment of the second aspect tend to emphasize the differences between the embodiments, and their identical or similar aspects can be referenced with each other. For the sake of simplicity, a repeated description is omitted herein. In addition, the heat dissipation assembly of the electric control box proposed in the embodiment of the first aspect and the heat dissipation assembly of the electric control box proposed in the embodiment of the second aspect can also be combined with each other. For example, in some embodiments, the electric control box can have both the heat dissipation assembly of the embodiment of the first aspect and the heat dissipation assembly of the embodiment of the second aspect.
Described above are only some specific embodiments of the present disclosure, but the scope of protection of the present disclosure is not limited to this. Any changes or replacements that can be easily conceived by those skilled in the art within the technical scope disclosed by the present disclosure should be covered within the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure should be accorded with the scope of protection of the claims.
