Detailed ways

The existing air conditioning system usually includes an indoor unit and an outdoor unit, and the outdoor unit is usually equipped with an electric control box inside the body. The function of the electric control box is to control the indoor unit and the outdoor unit of the air conditioning system. Generally, a circuit board assembly is installed inside the box body of the electric control box, and the circuit board assembly includes the circuit board and the electronic components provided thereon. When the air conditioning system is in working condition, the electronic components inside it will release a large amount of heat. Therefore, the electronic components in the electric control box have a high failure rate and often need to be repaired. However, the electric control box is located inside the outdoor unit, making it inconvenient to disassemble and assemble during maintenance.

In the technical solution of this application, a heat exchanger connected to the air conditioning refrigerant system through a refrigerant pipe is provided in the electric control box. The heat exchanger cools down through the phase change of the refrigerant, which can reduce the temperature of the electronic components in the electric control box and reduce the temperature of the electronic components. The failure rate of components is reduced and the reliability of electronic control is improved.

If you need to inspect the electronic components in the electric control box, you may need to dismantle the heat exchanger in the electric control box. This requires destructively cutting off the refrigerant pipe connected to the heat exchanger and recovering the refrigerant. When the electric control box is installed back to its original position, the cut refrigerant pipe needs to be re-welded. This disassembly and assembly method is still inconvenient.

In this application, the electric control box adopts a split design. The electric control box includes a box body and a connecting seat. The electronic components are arranged in the box body and the heat exchanger is arranged in the connecting seat. This allows the box body of the electric control box to be positioned relative to the connecting seat. The relative position is variable. When it is necessary to inspect the electronic components in the electric control box, it is only necessary to move the box body of the electric control box to a position convenient for inspection, without moving the connection base and the heat exchanger arranged in the connection base, that is, There is no need to cut off and re-weld the refrigerant pipe, making the maintenance process simpler and easier.

In addition, the electric control box is provided inside the casing of the outdoor unit. The casing is also equipped with other components of the air conditioning device, such as compressors, gas-liquid separators, complex refrigerant pipelines, etc. When it is necessary to inspect these components in the casing, It is also often necessary to disassemble and assemble the electronic control box to make the operating space larger. This solution in this application can easily disassemble the relatively large box body of the electric control box, making it more convenient to inspect and repair other components of the outdoor unit.

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of this application.

Referring to FIGS. 1 to 5 , the air conditioning device 200 provided by the present application includes a housing 210 and an electric control box 100 . The electric control box 100 includes a box assembly 110 , a circuit board assembly 120 and a heat exchanger assembly 130 . The box assembly 110 includes The box body 111 and the connecting seat 131, the box body 111 has a first receiving cavity 101, the circuit board assembly 120 is arranged in the first receiving cavity 101; the heat exchanger assembly 130 includes a heat exchanger 132, the box body 111 and the connecting seat 131 are separated Integral connection, and the box body 111 has a first opening 1111; the connection base 131 has a second accommodation cavity 102, and the heat exchanger 132 is disposed in the second accommodation cavity 102, that is, the heat exchanger 132 and the circuit board assembly 120 are separately located in the box body 111 and the connecting base 131 are in two different spaces, and the box body 111 is movably arranged relative to the connecting base 131, that is, the box body 111 and the connecting base 131 are independent of each other. When repairing the circuit board assembly 120, the box body 111 can be directly moved to a suitable position without disassembling both the box body 111 and the heat exchanger 132, which simplifies the technical difficulty of the repair operation. Even if the box body 111 needs to be disassembled during maintenance, the heat exchanger 132 does not need to be disassembled, which further ensures the convenience of the maintenance work and avoids the impact and damage to the connecting pipeline of the heat exchanger 132 caused by repeated disassembly. In addition, when the compressor, gas-liquid separator, complex refrigerant pipeline and other components in the casing of the air conditioning device 200 need to be inspected, the electronic control box often needs to be disassembled and assembled. The solution of the present application can easily disassemble the electric control box. The relatively larger box body 111 of 100 makes the operating space larger and makes it easier to inspect and repair other components of the outdoor unit.

Moreover, since the heat exchanger 132 and the circuit board assembly 120 are located in different spaces, the solution of the present application can also protect the circuit board assembly 120 from the condensation generated around the heat exchanger 132 as much as possible.

In the air conditioning device, the frequency of maintenance of the electronic components on the circuit board assembly 120 of the electric control box 100 is relatively high. It is often necessary to disassemble the electric control box 100 from the inside of the casing of the air conditioning device to the outside of the casing to inspect the electronic components in the electric control box 100 . However, the electronic control box 100 may be provided with components such as a refrigerant pipe or a heat exchanger 132, and these components are connected in the flow path of the refrigerant system. When the electronic components in the electric control box 100 need to be inspected, if the entire electric control box 100 is disassembled outside the casing, the refrigerant pipeline needs to be destructively cut off and the cooling medium in the refrigerant pipeline needs to be recovered; After the inspection is completed, when the electric control box 100 is installed into the casing, the cut refrigerant pipeline needs to be re-welded, and such an inspection process will be very cumbersome.

In the embodiment of the present application, the box assembly 110 in the electric control box 100 adopts a split design and is divided into different components such as the box body 111 and the connection base 131. The electronic components in the electric control box 100 are located in the box body 111, and the evaporator is installed in the box body 111. Installed on the connecting seat 131, the evaporator is connected in the flow path of the refrigerant system through the refrigerant pipeline. The box body 111 and the connecting base 131 are detachably connected. The connecting base 131 is fixedly installed in the air conditioning device, and the box body 111 is movable relative to the connecting base 131 . In this way, when the electronic components in the electric control box 100 need to be inspected and repaired, the box body 111 and the connecting base 131 can be separated, so that the electronic components provided in the box body 111 can be easily inspected or repaired. There is no need to disassemble the evaporator, which avoids the cumbersome process of cutting off and re-welding the refrigerant pipeline caused by disassembling the evaporator, making the disassembly and assembly process simpler and easier. The heat exchanger 132 cools the air through a phase change method. The principle may be that the refrigerant inside the heat exchanger 132 circulates with the inside of the air conditioning and refrigeration system, thereby absorbing heat through the phase change of the refrigerant to reduce the heat inside the electronic control box 100. The temperature of the air or air flow, thereby dissipating heat from the circuit board assembly 120 through the relatively low temperature air flow.

The electric control box 100 is provided inside the casing of the outdoor unit. Other components of the air conditioning device 200 are also provided in the casing, such as a compressor, a gas-liquid separator, and complex refrigerant pipelines. When it is necessary to inspect and repair these components in the housing, it is often necessary to disassemble and assemble the electronic control box 100 to make the operating space larger. The technical solution provided by this application can easily disassemble the relatively large box body 111 of the electronic control box 100, making it more convenient to inspect and repair other components of the outdoor unit.

Please refer to Figures 1 to 8. In some embodiments, the box 111 is detachably disposed on the connection base 131; the connection base 131 has a receiving space 1301, and the heat exchanger assembly 130 is pullable relative to the connection base 131. The heat exchanger assembly 130 is configured to dissipate heat from the circuit board assembly 120 .

That is to say, in the structure of the electric control box 100 of the present application, the circuit board assembly 120 and the heat exchanger assembly 130 are installed separately and are located in different spaces. The box body 111 can be detached from the connection base 131, and the heat exchanger The component 130 can be pulled out from the accommodation space 1301 of the connection base 131, thereby facilitating separate maintenance operations on the circuit board assembly 120 in the box 111 or the heat exchanger assembly 130 in the accommodation space 1301. Do not interfere with each other during maintenance. Moreover, since the heat exchanger assembly 130 and the circuit board assembly 120 are located in different spaces, condensation generated by the refrigerant heat dissipation device can be prevented from affecting the normal operation of the circuit board assembly 120 in the box 111 . At the same time, the heat exchanger assembly 130 can dissipate heat for the circuit board assembly 120 .

Referring to FIG. 4 , the heat exchanger assembly 130 is pullably arranged relative to the connection base 131 , and when the heat exchanger assembly 130 is in the pulled-out state, the heat exchanger 132 is located outside the accommodation space 1301 . It should be noted that the heat exchanger assembly 130 is configured to be pullable, so when maintaining the heat exchanger 132, the heat exchanger assembly 130 can be directly pulled out, which facilitates maintenance operations.

For example, the pipeline connecting the heat exchanger 132 to the air conditioning and refrigeration system can be configured as a flexible connecting pipeline with a certain extended length. When the heat exchanger assembly 130 is extracted from the accommodation space 1301, due to the connecting pipeline It has a certain length, and when the heat exchanger 132 can be extracted from the accommodation space 1301, the cooling medium in the heat exchanger 132 does not need to be discharged, and the connecting pipe does not need to be disconnected to perform maintenance operations, which is convenient and fast. The suitable length of the connecting pipe is to allow the heat exchanger assembly 130 to protrude from the accommodation space 1301 to control the space occupied by the connecting pipe.

In a possible implementation, as shown in Figures 5-6, the heat exchanger assembly 130 includes a shell 133 and a heat exchanger 132. When the heat exchanger assembly 130 is located in the accommodation space 1301, the box 111 and the shell 133 together form a receiving cavity, and the heat exchanger 132 is received in the receiving cavity and dissipates heat to the circuit board assembly 120 . The shell 133 mentioned here refers to the protective shell of the heat exchanger 132 itself. The box body 111 and the shell 133 together form a receiving cavity, which means that the internal spaces of the box body 111 and the shell 133 are connected with each other, so that the heat exchanger 132 located in the receiving space 1301 of the connecting seat 131 can be located in the box body 111 The circuit board assembly 120 dissipates heat, that is, a heat dissipation channel is formed inside the accommodation cavity.

In this embodiment, through the detachable arrangement of the box body 111 and the connecting seat 131, and the detachable arrangement of the heat exchanger assembly 130 in the accommodation space 1301 of the connecting seat 131, the circuit board assembly 120 and the heat exchanger assembly are processed. During the maintenance of 130, the two do not interfere with each other, which is convenient and fast. In addition, the inside of the box 111 and the inside of the shell 133 of the heat exchanger 132 are connected to form a heat dissipation air path, which ensures a good heat dissipation effect of the heat exchanger assembly 130 on the circuit board assembly 120. At the same time, the circuit board assembly 120 and the heat exchanger 132 are separated. In different spaces, condensation generated on the surface of the heat exchanger 132 will not affect the circuit board assembly 120, ensuring the good working condition of the electric control box 100 and extending the service life of the electric control box 100.

Continuing to refer to FIG. 7 , the above-mentioned connection base 131 includes a first support part 1303 and a second support part 1304 . The first support part 1303 and the second support part 1304 together form an accommodation space 1301 . The second support part 1304 is used for Carrying heat exchanger 132.

In an optional implementation, as shown in FIGS. 4 and 7 , the second support part 1304 is provided along the horizontal direction, and the second support part 1304 and the first support part 1303 jointly define and communicate with the accommodation space 1301 The lateral opening is configured for the heat exchanger assembly 130 to be extracted from the accommodation space 1301 . That is, the shell 133 surrounded by the second support part 1304 and the first support part 1303 is not completely closed, but has an opening on its side. This opening can essentially be regarded as an operation window to facilitate heat exchange. Take out the device 132.

Possibly, as shown in FIG. 7 , a guide surface 1324 is provided on the side of the second support part 1304 facing the lateral opening, and the guide surface 1324 gradually slopes outward from the inside of the lateral opening to the outside of the lateral opening. When the heat exchanger assembly 130 is taken out from the accommodation space 1301, the guide surface 1324 can assist the heat exchanger 132 to slide out quickly, thereby making it easier to take out the heat exchanger 132.

For example, the guide surface 1324 extends to the bottom surface of the connecting seat 131 . Understandably, the heat exchanger components When 130 slides down from the guide surface 1324, if the guide surface 1324 directly extends to the bottom, the heat exchanger assembly 130 can directly slide down to the bottom along the guide surface 1324, because there is a guide during the entire process of taking out the heat exchanger 132. The surface 1324 is used for support, so the removal process of the heat exchanger 132 is safer and more reliable, and problems such as slipping or bumping during manual removal are avoided, which greatly saves manpower.

In some embodiments, a closed air path is formed in the above-mentioned accommodation cavity, and the heat exchanger 132 cools the air through a refrigerant phase change method. The air path is configured to circulate the air cooled by the heat exchanger 132 and to The circuit board assembly 120 performs heat exchange.

Further, as shown in Figures 5 and 6, the box body 111 has a first accommodation cavity 101, the shell has a second accommodation cavity 102, the heat exchanger 132 is located in the second accommodation cavity 102, and the heat exchanger assembly 130 is located in the accommodation cavity. When inside the space 1301, the first accommodation cavity 101 and the second accommodation cavity 102 are connected with each other to jointly form an accommodation cavity, so that the gas cooled by the heat exchanger 132 can circulate in the first accommodation cavity 101 and the second accommodation cavity 102. , to achieve the effect of dissipating and cooling the circuit board assembly 120 .

As shown in Figure 6, in order to achieve communication between the first accommodation cavity and the second accommodation cavity, the bottom of the first accommodation cavity 101 has a first opening 1111; the side of the second accommodation cavity 102 facing the box is provided with a second opening 1311 , the second opening 1311 is correspondingly connected with the first opening 1111, so that the first accommodating cavity 101 and the second accommodating cavity 102 form the above-mentioned air path.

It is easy to understand that in order for the heat exchanger 132 to be located in the entire air path and to cool the circuit board assembly 120, the housing 133 must have an opening so that the first accommodation cavity 101 and the second accommodation cavity 102 can communicate to form heat dissipation. wind path.

Further, as shown in FIG. 7 , the connecting base 131 has an escape hole 1302 , the escape hole 1302 is provided between the first opening and the second opening 1311 , and the first opening, the escape hole 1302 and the second opening 1311 are connected correspondingly.

It can be understood that the heat exchanger assembly 130 is disposed in the accommodation space 1301 inside the connection base 131, and the second opening 1311 is opened on the shell 133 of the heat exchanger 132. If the second opening 1311 is connected to the box 111 If the first opening is connected, an escape hole 1302 needs to be opened on the connecting seat 131 at a position corresponding to the first opening and the second opening 1311, so that the first cavity 1011 and the second cavity 1012 are connected to form an air path.

In addition, an isolation member 140 is provided in at least one of the first accommodation cavity 101 and the second accommodation cavity 102. The isolation member 140 separates at least one of the first accommodation cavity 101 or the second accommodation cavity 102 into the aforementioned air path.

It should be noted that in order to achieve good heat dissipation effect for the circuit board assembly 120 in the box 111, the air path can be divided into two parts of space, one part of which is used to circulate the cold air cooled by the heat exchanger 132, and the other part of the space. The circuit board assembly 120 is disposed in the space, and the hot air formed after dissipating heat for the circuit board assembly 120 is circulated. The hot air and the cold air are divided into two independent paths in turn, which can avoid the cold air and hot air being cooled by the heat exchanger 132. The air is mixed, causing the temperature of the cold air to increase, reducing the heat dissipation effect on the circuit board assembly 120 .

In one embodiment, referring to FIGS. 5 and 6 , the isolation member 140 includes a first isolation member 141 disposed in the first accommodation cavity 101 , and the first isolation member 141 separates the first accommodation cavity 101 into first cavities. The body 1011 and the second cavity 1012, the first cavity 1011 and the second cavity 1012 are all connected with the first opening.

It can be understood that since the first cavity 1011 and the second cavity 1012 are to form a connected air path, the first cavity 1011 and the second cavity 1012 must be connected to the first opening. For example, the circuit board assembly 120 is disposed in the first cavity 1011, and the cold air cooled by the heat exchanger 132 is in the second cavity 1012. Then the cold air in the second cavity 1012 needs to be circulated into the first cavity. The heat dissipation of the circuit board assembly 120 can be achieved within 1011.

Based on this, the first cavity 1011 and the second cavity 1012 are connected through the first vent 1411 so that the cold air in the first cavity 1011 circulates into the second cavity 1012. The first ventilation opening 1411 is located at an end of the first isolation member 141 away from the connection base 131 , and the circuit board assembly 120 is disposed in the first cavity 1011 .

It is easy to understand that, since the heat exchanger 132 is disposed in the connecting seat 131 , the cold air in the second cavity 1012 comes from an end close to the heat exchanger 132 . If you want to form a circulating air path and allow the cold air to enter the first cavity 1011 and cool down the circuit board assembly 120, the cold air should flow from one end of the circuit board assembly 120 to the other end of the circuit board assembly 120, that is, The air flows from the end far away from the connection base 131 to the radiator 150 in the connection base 131 for cooling, thus forming a circulating air path. Therefore, only when the first vent 1411 is located at the end far away from the connection base 131 can the above-mentioned circulation path of the air path be realized.

As for the specific implementation form of the first vent 1411, for example, a through hole can be opened in the first isolator 141 as a vent, or a gap can be left between the end of the first isolator 141 away from the connection base 131 and the inner wall of the box 111. The gap serves as a ventilation opening and is not particularly limited here.

Figure 8 is a schematic structural diagram of a heat exchanger assembly of an electric control box provided by an embodiment of the present application.

Exemplarily, as shown in Figure 8, the housing 133 includes a bottom plate and a plurality of side plates connected to the circumferential outside of the bottom plate. The bottom plate and the side plates together form the second accommodation cavity 102, and the edge of the side plate away from the bottom plate forms a Second opening 1311. That is, the second opening 1311 is not provided with a cover plate, but is directly connected to the first opening. The above-mentioned bottom plate and multiple side plates can be integrally formed, or can be detachably spliced to each other to facilitate the maintenance of other components inside the housing 133 .

Among them, the shell 133 is detachably fixed on the side wall of the first support part 1303 to facilitate the removal of the heat exchanger assembly 130 from the side wall of the first support part 1303.

Optionally, continuing to refer to FIG. 8 , the edge of the side panel away from the bottom panel has a flange 134 , and the flange 134 and the first support part 1303 are arranged in close contact. It is easy to understand that the above-mentioned flange 134 is provided to facilitate the fixation of the housing 133 and also to facilitate the disassembly of the housing 133 . On the other hand, the bending part and the first support part 1303 are in contact with each other to ensure good sealing of the air path, so as to prevent the air in the air path from leaking out or the outside air from entering the air path and affecting the dispersion. Thermal effect.

In addition, as shown in FIGS. 5 and 6 , the isolation member 140 also includes a second isolation member 142 disposed in the second accommodation cavity 102 . The second isolation member 142 separates the second accommodation cavity 102 into a third cavity 1021 and a third cavity 1021 . The fourth cavity 1022, the third cavity 1021 and the fourth cavity 1022 are all connected with the second opening 1311, and the third cavity 1021 is connected with the first cavity 1011 correspondingly, and the fourth cavity 1022 is connected with the second cavity 1012 is connected correspondingly; the third cavity 1021 and the fourth cavity 1022 are connected through the second vent 1412, the heat exchanger 132 is arranged in the third cavity 1021 or the fourth cavity 1022, and the second vent 1412 is located in the exchanger. The side of the heater 132 opposite to the first opening.

It should be noted that the gas that absorbs heat and heats up after flowing through the circuit board flows back to the heat exchanger 132. The refrigerant circulates in the heat exchanger 132 and can cool the gas around it. The cooled gas flows in through the second opening 1311. The gas in the second cavity 1012 then enters the first cavity 1011 through the first vent 1411. After the gas in the first cavity 1011 flows through the circuit board assembly 120, it flows back to the heat exchanger 132 for cooling. Circulation of gas in the entire air path is achieved, thereby achieving better heat dissipation and cooling effect on the circuit board assembly 120 .

Optionally, continuing to refer to FIGS. 5 and 6 , a gap is left between the side of the second isolation member 142 close to the bottom plate and the bottom plate, and the gap serves as the second vent 1412 . Similar to the arrangement of the first vent 1411, this is only a simpler arrangement of the vents because there is no need to modify the second isolation member 142. In fact, the method of opening a vent in the second isolation member 142 can also be adopted, as long as the third cavity 1021 and the fourth cavity 1022 are connected.

In some embodiments, continuing to refer to Figures 5 and 6, the electronic control box 100 further includes a fan assembly 160. The fan assembly 160 includes at least one fan disposed in the air path, and the fan is configured to drive air to circulate along the air path, The air is cooled by the heat exchanger 132 and then flows to the circuit board assembly 120 to cool down the circuit board assembly 120 . The function of the fan is to provide power for air circulation in the air path. The number of fans can be considered according to the size of the space, the amount of heat generated by the circuit board assembly 120, and the requirements for heat dissipation speed.

It can be understood that the heat exchanger 132 may be an evaporator, and the evaporator is connected to the refrigerant flow path 300 of the air conditioning device, and is configured to perform cooling and temperature reduction through phase change of the refrigerant flowing through the evaporator. For example, the inlet of the evaporator can be connected to the low-pressure liquid refrigerant flow path in the refrigerant flow path 300 , and the outlet of the evaporator can be connected to the low-pressure gaseous refrigerant flow path in the refrigerant flow path 300 , so that the phase change from liquid to liquid can be achieved by the refrigerant. It absorbs heat into the gaseous state and reduces the temperature of the air flow in the electric control box 100 .

In the air conditioning device, the frequency of maintenance of the electronic components on the circuit board assembly 120 of the electric control box 100 is relatively high. It is often necessary to disassemble the electric control box 100 from the inside of the casing of the air conditioning device to the outside of the casing to inspect the electronic components in the electric control box 100 . In this application, the evaporator is installed in the electronic control box, and the evaporator is connected in the flow path of the refrigerant system through a refrigerant pipe.

When the electronic components in the electric control box 100 need to be inspected, if the entire electric control box 100 is disassembled outside the casing, the refrigerant pipeline connected to the evaporator needs to be destructively cut off and the refrigerant pipeline needs to be recovered. cooling medium in the cooling medium; after the maintenance is completed, when the electric control box 100 is installed into the casing, the cut refrigerant pipeline needs to be re-welded, and such a maintenance process will be very cumbersome.

In the embodiment of the present application, the box assembly 110 in the electric control box 100 adopts a split design and is divided into different components such as the box body 111 and the connection base 131. The electronic components in the electric control box 100 are arranged in the box body 111, and the evaporator is installed in the connecting seat 131. The evaporator is connected in the refrigerant system flow path through the refrigerant pipeline. The box body 111 and the connecting base 131 are detachably connected. The connecting base 131 is fixedly installed in the air conditioning device, and the box body 111 is movable relative to the connecting base 131 . In this way, when the electronic components in the electric control box 100 need to be inspected and repaired, the box body 111 and the connecting base 131 can be separated, so that the electronic components provided in the box body 111 can be easily inspected or repaired. There is no need to disassemble the evaporator, which avoids the cumbersome process of cutting off and re-welding the refrigerant pipeline caused by disassembling the evaporator, making the disassembly and assembly process simpler and easier.

In addition, the electric control box 100 is provided inside the casing of the outdoor unit. The casing is also equipped with other components of the air conditioning device, such as compressors, gas-liquid separators, complex refrigerant pipelines, etc. When it is necessary to inspect and repair these components in the housing, it is often necessary to disassemble and assemble the electronic control box 100 to make the operating space larger. This solution in the present application can easily disassemble the relatively large box body 111 of the electronic control box 100, making it more convenient to inspect and repair other components of the outdoor unit.

It should be noted that the detachable connection method between the box body 111 and the connecting seat 131 mainly refers to the variable relative position between the box body 111 and the connecting seat 131, so that the box body 111 and the connecting seat 131 are in a variable relative position. Detachable state. Among them, the detachable connection methods between the box body 111 and the connection base 131 include but are not limited to the following:

1. The box body 111 and the connecting base 131 can only change their relative positions, but they remain connected before and after disassembly. The connection between the box body 111 and the connecting base 131 can be rotatable, for example. Connected together, or a sliding connection between the two, etc.

2. The box body 111 and the connecting base 131 are completely separated when disassembled. At this time, the box body 111 and the connecting base 131 may be connected without any other structure, and the box body 111 can move freely relative to the connecting base 131 .

The refrigerant flow path 300 in the air conditioning device may be a circulation loop formed by sequentially connecting the compressor, condenser, expansion valve and evaporator in the air conditioning device. The above components are connected through pipes for the circulation of refrigerant. The air conditioning device passes through the refrigerant flow. The phase change during the circulating flow of the refrigerant in the refrigerant flow path 300 performs heat exchange to achieve the function of cooling or heating, and the heat exchanger 132 in the electric control box 100 can be connected to the main flow path of the refrigerant flow path 300, or can be connected In the branch flow path of the refrigerant flow path 300, the embodiment of the present application does not specifically limit this.

Generally, the specific structure of the circuit board assembly 120 includes a circuit board and electronic components disposed on the circuit board. The electronic components will generate a large amount of heat during operation, which will affect the normal operation of the electronic components. Therefore, the above-mentioned heat dissipation structure essentially The above is to cool down electronic components.

Continuing to refer to Figures 5 and 6, the fan is disposed in the first accommodation cavity 101. The fan includes an air inlet side 1611 and an air outlet side 1612. The air inlet side 1611 faces the first vent 1411, and the air outlet side 1612 faces the circuit board. Component 120. It can be understood that the cold air in the first cavity 1011 will enter the second cavity 1012 through the first vent 1411, and the power of the cold air flow is provided by the fan, that is, it is sucked in from the air inlet and flows out from the air outlet. And take away the heat generated by the electronic components through the circuit board assembly 120 . It should be noted that the air inlet side 1611 mentioned here faces the first vent 1411, which means that the air inlet side 1611 faces the first vent 1411, but does not necessarily face the first vent 1411, and the air outlet side 1612 does not necessarily face the circuit board assembly 120 either.

In addition, as shown in Figures 5 and 6, the electrical control box 100 also includes a heat sink 150. The heat sink 150 is disposed in the receiving cavity, and the heat sink 150 is attached and fixed to the back of the circuit board assembly 120. The heat sink 150 is configured To dissipate heat from the circuit board assembly 120 through thermal conduction.

In this embodiment, by arranging the heat sink 150 in the first accommodation cavity 101, another way of dissipating heat for the circuit board assembly 120 is added, which has dual paths of gas circulation and heat conduction cooling, making the heat dissipation effect better. Directly attaching the heat sink 150 to the back of the circuit board assembly 120 can make the heat conduction faster, thereby achieving the best heat dissipation effect. In addition, due to the circulation of air flow in the first accommodation chamber 101, condensation generated by rapid cooling due to heat conduction can be taken away.

In this embodiment, the two cooling methods complement each other to achieve a good cooling effect while avoiding the impact of condensation generated in the first accommodation cavity 101 on the circuit board.

Please refer to FIGS. 9 to 12 . In some embodiments, the box body 111 may be located above the connecting seat 131 , and a second opening 1311 is provided on the side of the second accommodation cavity 102 facing the bottom of the box body 111 ; the box body 111 is opposite When the connecting seat 131 rotates to the first position, the second opening 1311 and the first opening 1111 are provided correspondingly, so that the first accommodating cavity 101 and the second accommodating cavity 102 are connected to form a closed air path, and the air path is configured to allow the exchanger to The air cooled by the heat exchanger 132 exchanges heat with the circuit board assembly 120. That is, the heat dissipation of the circuit board assembly 120 is achieved through the gas circulation flow inside the closed air path. The hot air is cooled by the heat exchanger 132 and then flows through the circuit board assembly. 120 to achieve good heat dissipation effect.

The box body 111 and the connecting base 131 can be rotationally connected. When the box body 111 is rotated to the first position relative to the connecting base 131, the side walls of the box body 111 and the side walls of the connecting base 131 are flush with each other, so that The electrical control box 100 has a flat outer wall.

When the box body 111 rotates to the second position relative to the connecting base 131, the positions of the box body 111 and the connecting base 131 By staggering each other, some maintenance operations can be performed on the box 111 or the radiator without disassembling the heat exchanger 132 .

Possibly, the box body 111 of the electric control box 100 rotates along the vertical axis. When the box body 111 is in the first position, the box body 111 is disposed above the connecting seat 131 . This embodiment provides an exemplary relative positional relationship between the box body 111 and the connection base 131 of the electronic control box 100. When the box body 111 is in the first position (that is, the box body 111 and the connection base 131 are in a normal mating state) , the connecting seat 131 is provided on the bottom side of the box body 111 . The rotating axis of the box 111 is a vertical axis, that is, the rotating axis of the box 111 is located on one side of the box 111 and is not in the same direction as the heat exchanger 132. When the box 111 rotates relative to the connecting seat 131 , there will be no interference between the two.

In addition, as shown in FIG. 1 , the bottom wall of the box 111 and the top wall of the connecting base 131 are parallel to each other. When the box 111 is in the first position, the bottom wall of the box 111 and the top wall of the connecting base 131 are in contact with each other.

It can be understood that in order to form a closed air path, the first accommodation cavity 101 inside the box 111 and the second accommodation cavity 102 inside the connection base 131 need to be connected to each other, and the way of communication is between the first accommodation cavity 101 and Corresponding openings are provided on the wall of the second accommodation cavity 102 , that is, the first opening 1111 and the second opening 1311 are respectively provided on the bottom wall of the box body 111 and the top wall of the connecting seat 131 . In order to ensure the airtightness of the air path, the bottom wall of the box 111 and the top wall of the connecting seat 131 should be flat and close to each other, leaving no gaps as much as possible, so as to ensure that the cooling gas in the air path does not easily escape, and the hot air from the outside does not easily escape. It is not easy to enter the inside of the air duct, thereby ensuring normal internal gas circulation and achieving a good cooling effect. Therefore, the bottom wall of the box body 111 and the top wall of the connecting seat 131 are arranged parallel to each other in order to achieve good fit and avoid leaving a gap between the two, which may cause internal cold air to overflow or external hot air to enter, thereby affecting the box body. 111The heat dissipation effect of the internal electrical components.

Further, as shown in FIG. 9 , the edge shapes of the first opening 1111 and the second opening 1311 match each other. It can be understood that in order to form a closed air path, after the bottom wall of the box 111 and the top wall of the connecting seat 131 are attached to each other, the edges of the corresponding first opening 1111 and the second opening 1311 should be completely consistent, so that the Avoid gaps, which may lead to loose air duct sealing and affect the heat dissipation effect of internal electrical components.

In some embodiments, when the box body 111 is in the second position, the projection ranges of the box body 111 and the connecting base 131 in the vertical direction do not overlap with each other. The advantage of this arrangement is that when the box 111 rotates relative to the connecting base 131, for example, when the box 111 rotates to the maximum angle, the box 111 and the connecting base 131 completely belong to two different planes. When performing some maintenance operations, it will not have any impact on the connecting seat 131, nor will it be hindered by the connecting seat 131. Correspondingly, when performing maintenance operations on the heat exchanger 132 in the connecting seat 131, it will not be affected by the box. 111 obstacles. In particular, some operations need to be performed on the inside of the box 111 and the connecting base 131 through the first opening 1111 and the second opening 1311. If the first opening 1111 and the second opening 1311 are vertically connected, If the projections in the straight direction overlap to a certain extent, they may touch each other during operation, causing inconvenience in operation. If the box 111 is rotated to a certain position and can be completely offset from the connection base 131, there will be no such problem. occur.

Referring to FIGS. 9 to 12 , in some other optional embodiments, the electronic control box 100 further includes an isolation member 140 , which is disposed in at least one of the first accommodation cavity 101 and the second accommodation cavity 102 , and separate the first accommodation cavity 101 and the second accommodation cavity 102 into the aforementioned air passages.

It should be noted that, in order to achieve good heat dissipation effect for the circuit board assembly 120 in the box 111, the air path can be divided into two parts of space, one part of the space is used to circulate the cold air cooled by the heat exchanger 132, and the other part of the space is used to circulate the cold air cooled by the heat exchanger 132. A circuit board assembly 120 is provided inside. Dividing the hot air and the cold air into two independent paths in turn can prevent the mixing of the cold air and the hot air cooled by the heat exchanger 132 from being unable to maintain the temperature of the cold air, thereby reducing the heat dissipation effect on the circuit board assembly 120 .

Exemplarily, with reference to FIGS. 9 to 12 , the isolation member 140 includes a first isolation member 141 disposed in the first accommodation cavity 101 , and the first isolation member 141 separates the first accommodation cavity 101 into a first cavity 1011 and the second cavity 1012, and the first cavity 1011 and the second cavity 1012 are connected through the first vent 1411. The first cavity 1011 and the second cavity 1012 are both connected to the first opening 1111. The circuit board The component 120 is disposed in the first cavity 1011.

It can be understood that the first vent 1411 is provided to connect the first cavity 1011 and the second cavity 1012 to form an air path for gas circulation. When the circuit board assembly 120 is placed in the first cavity 1011, the cold air circulating in the second cavity 1012 can enter the first cavity 1011 through the first vent 1411, and the cold air flows through the circuit board assembly 120. The heat dissipation and cooling of the circuit board assembly 120 is achieved. That is, the circuit board assembly 120 of the present application is cooled by circulating low-temperature gas. During the circulation process of the gas, at least part of the condensation generated after cooling in the first cavity 1011 can also be taken away, so that the first cavity 1011 can be kept as dry as possible while ensuring good cooling of the circuit board assembly 120 At the same time, the risk of damage to the circuit board assembly 120 caused by condensation is reduced.

Referring to FIGS. 9 to 12 , the circuit board assembly 120 in the box 111 includes a circuit board and electronic components. The circuit board is fixed on the first isolation member 141 , and the electronic components are arranged on the side of the circuit board away from the first isolation. One side of piece 141. This embodiment exemplifies one of the ways of fixing electronic components, that is, fixing against the first isolator 141. The advantage of this way of fixing is that the side of the first isolator 141 facing away from the circuit board Other heat dissipation structures may be provided, which may also have a heat dissipation and cooling effect on the circuit board assembly 120 . If this is not considered, in fact, the circuit board may also be fixed to, for example, the inner wall of the first accommodation cavity 101 .

In addition, a temperature sensor can be provided on the circuit board assembly 120 to detect the temperature of the electronic components, thereby controlling the flow of refrigerant flowing into the heat exchanger 132 to prevent the air flow in the air path from being too low and affecting the operation of the electronic components. Influence.

Exemplarily, based on the above technical solution of fixing the circuit board assembly 120 on the first isolator 141, a heat sink 150 can also be provided in the first accommodation cavity 101. The heat sink 150 is provided corresponding to the circuit board assembly 120, and the heat sink 150 is used for Dissipate heat from electronic components through thermal conduction.

Optionally, the heat sink 150 is attached and fixed to a side of the first isolation member 141 away from the circuit board assembly 120 .

In the above embodiment, by arranging the radiator 150 in the first accommodation cavity 101, another way of dissipating heat for the circuit board assembly 120 is added, and a dual path of gas circulation and heat conduction cooling is provided, so that the heat dissipation effect is better. The heat sink 150 is provided on the side of the first isolator 141 away from the circuit board assembly 120, which can achieve better heat dissipation effect by heat conduction, and due to the circulation of air flow in the first accommodation cavity 101, the heat generated by rapid cooling due to heat conduction can be taken away. Condensation, the two cooling methods complement each other, and while achieving a good cooling effect, the impact of condensation generated in the first accommodation cavity 101 on the circuit board assembly 120 is avoided.

Referring to FIGS. 9 to 12 , the isolation member 140 further includes a second isolation member 142 disposed in the second accommodation cavity 102 . The second isolation member 142 separates the second accommodation cavity 102 into a third cavity 1021 and a fourth cavity 1021 . Cavity 1022, the third cavity 1021 is connected to the first cavity 1011, the fourth cavity 1022 is connected to the second cavity 1012, and the heat exchanger 132 is disposed in the third cavity 1021 or the fourth cavity 1022. .

There is a second vent 1412 between the third cavity 1021 and the fourth cavity 1022. The second vent 1412 is located on the side of the heat exchanger 132 opposite to the first opening 1111.

It should be noted that the airflow that absorbs heat and heats up after passing through the circuit board assembly 120 flows to the heat exchanger 132. There is refrigerant circulating in the heat exchanger 132, which can cool the airflow passing around it. The cooled airflow flows in through the second opening 1311. The second cavity 1012 then enters the first cavity 1011 through the first vent 1411 to cool down the circuit board assembly 120. At this time, the air flow absorbs heat and heats up, and flows to the heat exchanger 132 again, thereby realizing the circulation of the air flow in the entire air path. circulation to achieve better cooling effect.

The second isolation member 142 is provided in the second accommodation cavity 102 to separate the second accommodation cavity 102 into a third cavity 1021 and a fourth cavity 1022. The third cavity 1021 and the fourth cavity 1022 are also used to separate the second accommodation cavity 102 from the second accommodation cavity 102. The incoming hot air flow and the outgoing cold air flow are spatially separated to prevent the incoming hot air flow and the cooled cold air flow from mixing with each other and affecting the cooling effect.

The first cavity 1011 and the third cavity 1021 are connected correspondingly, and the second cavity 1012 and the fourth cavity 1022 are connected correspondingly, so that the air path inside the entire electronic control box 100 forms a circular circulation air path, so as to Achieve smooth circulation of hot and cold airflow in the air path to cool down the circuit board assembly 120. Dividing the internal air path into two parts makes it easier to control the flow direction of the overall air flow in the air path, and control the hot air flow and cold air flow to flow according to their prescribed paths, without causing the hot air flow and cold air flow to mix and flow, resulting in poor cooling effect.

Referring to FIG. 9 , taking the heat exchanger 132 disposed in the third cavity 1021 as an example, the flow passes through the circuit board assembly 120 The airflow becomes a cold airflow after passing through the heat exchanger 132. The cold airflow enters the fourth cavity 1022 through the second vent 1412, and then flows into the second cavity 1012 from the fourth cavity 1022. The heat exchanger 132 is arranged at the The same path is also used in the four-cavity body 1022.

It is easy to understand that the second vent 1412 is located on the side of the heat exchanger 132 opposite to the second opening 1311. This is to ensure that only the air flow cooled by the heat exchanger 132 can pass through the third cavity 1021 and the fourth cavity. The cavity 1022 enters the second cavity 1012 to ensure that the air flow entering the second cavity 1012 has the lowest temperature.

In addition, a drain port can be provided on the heat exchanger 132 so that condensation can be discharged from the drain port to keep the space dry.

In addition, the electronic control box may also include a fan assembly 160. The fan assembly 160 includes at least one fan 161 disposed in the air duct. The fan 161 is configured to drive air to circulate along the air duct so that the air is cooled by the heat exchanger 132. , flows to the circuit board assembly 120, and cools the circuit board assembly 120. The function of the fan 161 is actually to provide power for the circulation of air flow in the air path. The number of fans 161 can be considered from aspects such as space size and heat dissipation speed requirements.

In some possible implementations, both the first isolation member 141 and/or the second isolation member 142 are plate-shaped. It should be noted that the main function of the first isolator 141 and the second isolator 142 is to separate the first accommodating cavity 101 and the second accommodating cavity 102 into two cavities respectively. Therefore, any structure of the separator plate can function as long as it can It can be used for any separation function. However, considering that the circuit board assembly 120 needs to be fixed on the first isolator 141, it is more convenient to choose a relatively flat plate-shaped structure, and the plate-shaped isolator 140 also makes the air flow in the air path smoother.

It should be noted that the specific structure, functional principles, etc. of the electronic control box 100 have been described in detail above and will not be described again here. Moreover, since the air conditioning device 200 adopts all the technical solutions in the above embodiments, it has at least all the beneficial effects brought by the technical solutions in the above embodiments, which will not be described again one by one.

Referring to Figures 9 to 12, the housing 210 includes uprights 211, and the box 111 is rotatably connected to one of the uprights 211. When the box 111 is in the second position, the box 111 extends from the housing 210. That is, the box body 111 is rotatably connected to the upright column 211, so that the box body 111 can be rotatably arranged relative to the connecting base 131, making the maintenance operation of the circuit board assembly 120 in the box body 111 more convenient.

In some embodiments, the air conditioning device may further include a limiting component, which is relatively fixed to at least one of the box body and the connecting seat, and fixes the box body in the first position, wherein the limiting component includes The limiting piece is provided on the connecting seat or the connecting base, and the limiting piece blocks the rotation track of the box body to stop the box body in the first position.

By using the hinge 212 to connect the box body 111 to the column 211, the flexible rotation of the box body 111 can be facilitated. When repairing components such as the circuit board assembly 120 in the box body 111, the box body 111 may only need to be rotated to a certain angle. It can be operated without disassembling the box body 111.

In some embodiments, the air conditioning device further includes a sealing member (not shown). When the box body 111 is in the first position, the first opening 1111 and the second opening 1311 are sealed by the sealing member.

Please refer to FIGS. 13 to 17 . In some embodiments, the socket 131 and the box body 111 are connected in sequence from top to bottom, and the box body 111 is moved relative to the connection base 131 so that the box body 111 moves below the connection base 131 When the box body 111 and the connecting seat 131 together constitute the detachable electric control box 100, and when the electric control box 100 is in an undetached state, the box body 111 and the connecting seat 131 together form a receiving cavity, and the connecting seat 131 and the box The projections of the bodies 111 in the vertical direction at least partially overlap, and both the heat exchanger 132 and the circuit board assembly 120 are located in the receiving cavity.

It can be understood that the box body 111 can move relative to the connecting base 131 so that the box assembly 110 is in a split or unsplit state. When the box assembly 110 is in an unsplit state, the box body 111 can be connected to the connecting base. 131 together form an accommodation cavity. At this time, the electric control box 100 can work to control the operation of the air conditioning device. When the box assembly 110 is in a disassembled state, the space behind the box 111 can be exposed, thereby facilitating the operator's inspection. Air conditioning units are inspected and repaired.

In some embodiments, the box body 111 can be rotated relative to the connecting seat 131 so that the box body 111 rotates below the connecting seat 131 and the connecting seats 131 together form a receiving cavity, or the box body 111 and the connecting seat 131 are arranged in a horizontal direction. The positions on are staggered from each other so that the box assembly 110 is in a disassembled state.

In addition, the air conditioning device also includes a column 211, the column 211 and the outdoor unit 230 are relatively fixed, and the box body 111 is rotatably connected to the column 211.

In some embodiments, the air conditioning device may also include a fan 161 and an isolation member 140. The isolation member 140 may be disposed in the accommodation cavity and divide the accommodation cavity into circulating air channels. The circuit board assembly 120 and the heat exchanger 132 circulate along the air duct. The extension direction of the channels is arranged in sequence, the heat exchanger 132 is located on the connecting seat 131, and the heat exchanger 132 is located at the top of the accommodation cavity. The heat exchanger 132 is configured to cool the heat exchanger passing through the heat exchanger 132 through the phase change of the cooling medium. The air is cooled, and the fan 161 is configured to drive the air to flow along the circulating air duct.

It can be understood that when the fan 161 is started, a cooling airflow can be formed in the accommodation cavity. The cooling airflow flowing in the accommodation cavity can flow through the heat exchanger 132 and the circuit board assembly 120 in sequence. When the cooling airflow enters the connection seat 131, and When passing through the top of the accommodation cavity, the cooling airflow will flow through the heat exchanger 132. When the heat exchanger 132 is working, the heat exchanger 132 can cool the cooling airflow, absorb the heat of the cooling airflow passing through, and reduce the cooling rate. The temperature of the air flow, therefore, the temperature of the cooling air flow can be lower than the surface temperature of the circuit board assembly 120 when it is working, Therefore, when the cooling air flows through the circuit board assembly 120, it can exchange heat with the circuit board assembly 120, take away the heat of the circuit board assembly 120, lower the temperature of the circuit board assembly 120, and achieve a heat dissipation effect.

It should be noted that in the embodiment of the present application, the box assembly 110 of the electric control box 100 adopts a split design, so that the box body 111 of the electric control box 100 can move relative to the connection base 131, that is, when the electric control box 100 is connected to the When the control box 100 is assembled into the air-conditioning device, the connecting seat 131 can be relatively fixed, and the box body 111 can move relative to the connecting seat 131. The heat exchanger 132 passing the cooling medium is arranged on the connecting seat 131. In the air-conditioning device When maintenance is required, the box body 111 can be moved without moving the connecting seat 131, cutting off the refrigerant pipeline and recovering the cooling medium, which facilitates the disassembly of the electronic control box 100 and improves the convenience of maintenance.

Those skilled in the art can understand that when the electronic control box 100 is applied to an air conditioning device, the electronic control box 100 can be installed in the casing 210 of the air conditioning device, and a compressor, a fan, and a cooling device can also be installed in the casing 210. The medium pipeline and other components, the connecting seat 131 can be fixedly connected to the casing 210 of the air conditioning device, and the box 111 can rotate relative to the casing 210 of the air conditioning device, so that the relative movement between the box 111 and the connecting seat 131 can be realized.

In some embodiments, the heat exchanger 132 may be an evaporator. The heat exchanger 132 may be connected to the refrigerant flow path 300 of the air conditioning device and configured to perform cooling through phase change of the refrigerant. That is, the heat exchanger 132 may use outdoor The cooling medium pipeline of the machine 230 plays the role of the heat exchanger 132 in the electronic control box 100, thereby achieving the effect of heat exchange. According to the working principle of the evaporator, the phase change of the cooling medium can be used to absorb the cooling airflow in the accommodation cavity. heat to achieve a cooling effect.

For example, the inlet of the evaporator is connected to the low-pressure liquid refrigerant flow path in the refrigerant flow path 300 , and the outlet of the evaporator is connected to the low-pressure gaseous refrigerant flow path in the refrigerant flow path 300 . The low temperature of the heat exchanger 132 will only affect the air and airflow in the accommodation cavity. Using the cooled airflow to dissipate heat can prevent the circuit board assembly 120 from condensation due to overcooling, ensuring that the circuit board assembly 120 can operate well.

It can be understood that the refrigerant flow path 300 in the air conditioning device may be a circulation loop formed by sequentially connecting the compressor, condenser, expansion valve and evaporator in the air conditioning device. The above components are connected through pipes for the circulation of refrigerant. The air conditioning device performs heat exchange through the phase change during the circulating flow of the refrigerant in the refrigerant flow path 300 to achieve the cooling or heating function, and the heat exchanger 132 in the electronic control box 100 can be connected to the main flow path of the refrigerant flow path 300 , it may also be connected in the branch flow path of the refrigerant flow path 300 , which is not specifically limited in the embodiment of the present application.

When it is necessary to repair the electronic components in the electric control box 100, if the entire electric control box 100 is disassembled into Outside the casing, the refrigerant pipeline connected to the evaporator needs to be destructively cut off and the cooling medium in the refrigerant pipeline needs to be recovered; after the inspection is completed, when the electric control box 100 is installed into the casing, it needs to be re-welded and cut off. Refrigerant pipeline, such maintenance process will be very cumbersome. The casing of the outdoor unit of the air conditioner is provided with other components, such as a compressor, a gas-liquid separator, and complex refrigerant pipelines. When these components fail, the position of the electronic control box 100 often needs to be moved to increase the operating space.

In the embodiment of the present application, the box assembly 110 in the electric control box 100 adopts a split design and is divided into different components such as the box body 111 and the connection base 131. The electronic components in the electric control box 100 are arranged in the box body 111, and the evaporator is installed in the connecting seat 131. The evaporator is connected in the refrigerant system flow path through the refrigerant pipeline. The box body 111 and the connecting base 131 are detachably connected. The connecting base 131 is fixedly installed in the air conditioning device, and the box body 111 is movable relative to the connecting base. In this way, when the electronic components in the electric control box 100 need to be inspected and repaired, the box body 111 and the connecting base 131 can be separated, so that the electronic components provided in the box body 111 can be easily inspected or repaired. There is no need to disassemble the evaporator, which avoids the cumbersome process of cutting off and re-welding the refrigerant pipeline caused by disassembling the evaporator, making the disassembly and assembly process simpler and easier. At the same time, the relatively large box assembly 110 of the electronic control box 100 can be easily disassembled, making it more convenient to inspect and repair other components of the air conditioner outdoor unit.

When the cooling airflow inside the accommodating cavity flows, it will not interact with the electric control box 100. External air convection can prevent external dust or mosquitoes from entering the housing cavity. When used in outdoor environments, it can also prevent rain and corrosion. At the same time, external water vapor cannot easily enter the electronic control box. 100, the water vapor content in the receiving cavity of the electric control box 100 is limited. When the heat exchanger 132 absorbs heat and cools the cooling air flow, it also has a dehumidifying effect on the air, so condensation is not easily generated in the electric control box 100.

The cooling airflow circulates; and when the box body 111 moves relative to the connecting seat 131, the projections of the box body 111 and the connecting seat 131 in the vertical direction may not overlap each other, exposing the space below the connecting seat 131, thereby facilitating the inspection of the air conditioning device. parts for maintenance.
