The air energy water heater mainly comprises a compressor, an evaporator, a condenser, a throttling device, an electric control device, a heat preservation water tank and other structures. The compressor, the evaporator, the condenser and the throttling device are connected through refrigerant pipes. The electric control device can control the compressor to work, and the heat released by the condenser can heat water in the heat preservation water tank. The cool air generated by the evaporator can be discharged outdoors or introduced into a kitchen to cool the kitchen.
In order to improve the heat dissipation problem of the electric control device 400, referring to fig. 1 and 2, the air energy water heater according to an embodiment of the present invention includes a machine head, wherein the machine head includes a housing 100, an evaporator 200, an air outlet device 300, the electric control device 400 and an air intake duct 500. The inside of the housing 100 is provided with an air passage in which the evaporator 200 is disposed, and divides the air passage into an air inlet chamber 113 and an air outlet chamber 114. The air outlet device 300 is located at one side of the evaporator 200, for example, the air outlet device 300 may be disposed in the air inlet cavity 113 or the air outlet cavity 114, so that air flows into the air inlet cavity 113, and cold air is formed after the air flows through the evaporator 200 and is blown out from the air outlet cavity 114. The air outlet device 300 has the function of enabling the air flow to contact with the evaporator 200 and improving the heat exchange efficiency of the evaporator 200. Since the refrigerant in the evaporator 200 can evaporate and absorb heat, the air flow can form cool air with a temperature lower than the ambient temperature after passing through the evaporator 200, and the cool air is blown out from the air outlet chamber 114. The electronic control device 400 is disposed inside the housing 100 and can be fixedly connected with the housing 100.
Referring to fig. 3, 4 and 5, the air induction duct 500 may be a hollow tubular structure, for example, the air induction duct 500 is an air duct. The air guide duct 500 may be a passage defined by various structures such as the housing 100 and a baffle. Taking the air induction channel 500 as an air pipe for example, two ends of the air pipe are respectively provided with a first air inlet 510 and a first air outlet 530, and the first air inlet 510 is communicated with the first air outlet 530. The first air inlet 510 is located in the air outlet chamber 114 and is in communication with the air outlet chamber 114, and the first air outlet 530 is disposed towards the electronic control device 400. Therefore, the cool air blown out from the air outlet cavity 114 can enter the first air inlet 510, and finally be blown out from the first air outlet 530 to the electronic control device 400.
It can be appreciated that, adopting the scheme of blowing type heat dissipation, compare in the formula of induced drafting heat dissipation, blowing type heat dissipation's air-out wind speed is bigger more concentrated, can effectively reduce the temperature of electric control device 400, improves cooling rate and radiating effect. The temperature of the cold air is lower than the temperature of the surrounding environment, and even if the temperature of the surrounding environment is high, the cold air can dissipate heat, so that the influence of the temperature of the environment is reduced when the electric control device 400 dissipates heat, and the situation that the electric control device 400 fails due to the overhigh temperature is improved.
Referring to fig. 2, in the embodiment of the present invention, the housing 100 has a cylindrical shape and is more attractive in shape. The shell 100 comprises a shell 110 and a water receiving disc 120, wherein the water receiving disc 120 is connected to the lower end of the shell 110, an air inlet cavity 113 and an air outlet cavity 114 are formed between the water receiving disc 120 and the shell 110, a second air inlet 111 and a second air outlet 112 are arranged on the shell 110 at intervals, the second air inlet 111 is communicated with the air inlet cavity 113, and the second air outlet 112 is communicated with the air outlet cavity 114. The second air inlet 111 and the second air outlet 112 may be provided with a plurality of air inlets, which can improve the air inlet efficiency and the air outlet efficiency, and simultaneously prevent larger foreign matters from entering the interior of the housing 100 through the second air inlet 111 or the second air outlet 112, so as to improve the protection performance of the housing 100. Because the condenser is easy to generate condensed water due to the reduced temperature of the condenser during operation, the water receiving tray 120 is used for receiving the condensed water, so that the condensed water is guided to a proper position for discharging after being collected. In other embodiments, the housing 100 may also have a square column shape, a sphere shape, or the like, and a suitable shape is selected according to practical situations.
Referring to fig. 2, 4 and 5, in the embodiment of the present invention, the air outlet device 300 is disposed in the air outlet cavity 114, or the air outlet device 300 is located at a side of the evaporator 200 facing away from the air inlet cavity 113. The air outlet device 300 comprises a motor 320, an axial flow wind wheel 330 and a bracket 340, wherein the bracket 340 can be fixedly connected to the water pan 120, can also be fixedly connected to the evaporator 200, and the evaporator 200 can be fixedly connected to the water pan 120. The motor 320 is mounted on the bracket 340, and the motor 320 is in driving connection with the axial flow wind wheel 330 to drive the axial flow wind wheel 330 to rotate. The air outlet device 300 is capable of making the air flow pass through the evaporator 200 by means of air suction, so as to facilitate blowing out most of the cool air from the second air outlet 112. It can be appreciated that when the air outlet device 300 is located in the air outlet cavity 114, the air outlet device 300 can be disposed at a position close to the inner wall of the housing 100, away from positions where various cables are located, so as to effectively avoid the situation that the cables enter the air outlet device 300 due to loosening, falling off and the like, and the cables are twisted off by the axial flow wind wheel 330.
It should be noted that, in another embodiment of the present invention, the air outlet device 300 may also be disposed in the air inlet cavity 113 to exchange heat by blowing air toward the evaporator 200. It can be appreciated that the air outlet device 300 is disposed in the air inlet cavity 113, and the air outlet device 300 is located approximately in the middle of the housing 100, and the space is larger, so that a larger axial flow wind wheel 330 can be used, thereby having a larger air outlet amount, and further improving the heat exchange efficiency of the evaporator 200. Of course, instead of using an axial flow wind wheel 330, a centrifugal wind wheel may be used. For example, the axial flow wind wheel 330 is used when the air outlet device 300 is arranged in the air outlet cavity 114, and the centrifugal wind wheel is used when the air outlet device 300 is arranged in the air inlet cavity 113. In particular, a suitable scheme is selected according to practical situations, and for convenience of explanation, in all the following embodiments, the air outlet device 300 is set in the air outlet cavity 114, and the air outlet device 300 includes an axial flow wind wheel 330.
Referring to fig. 4, in an embodiment of the present invention, the air outlet device 300 further includes an air guiding ring 310, where the air guiding ring 310 is located in the air outlet cavity 114. The air guide ring 310 is formed with a ventilation opening 311, and the axial flow wind wheel 330 is positioned at the ventilation opening 311. The wind-guiding ring 310 has the function of guiding the airflow direction so that most of the airflow is blown out from the second air outlet 112.
Referring to fig. 3 and 4, in the embodiment of the present invention, a groove 316 communicating with the ventilation opening 311 is formed at an end of the air guiding ring 310, for example, the groove 316 may be located at an end of the air guiding ring 310 facing away from the evaporator 200. The end of the recess 316 is formed with a bypass opening 315, the end of the recess 316 referring to the end of the recess 316 facing the vent opening. One end of the air guiding duct 500 is installed in the groove 316, and the first air inlet 510 is disposed towards the bypass opening 315. A portion of the cool air can thus enter the first air inlet 510 through the bypass opening 315 and finally be blown from the first air outlet 530 toward the electronic control unit 400. Through setting up the one end and the wind-guiding circle 310 of induced-draft duct 500 and being connected, when conveniently fixing induced-draft duct 500 position, can also make things convenient for in the air conditioning gets into induced-draft duct 500, structural design is reasonable, and the reliability is high. It should be noted that, the groove 316 may also be located at an end of the air guiding ring 310 facing the evaporator 200, where the first air inlet 510 is disposed facing the evaporator 200, so that the first air inlet can be used for air intake.
Referring to fig. 3, in the embodiment of the present invention, along the air outlet direction of the air outlet cavity 114, the inner wall of the air guiding ring 310 sequentially includes an inner edge 312, a transition section 313 and an outer edge 314. The bypass port 315 may be provided at the transition section 313 or the outer edge 314 to enable the first air intake 510 to intake air. It should be noted that, in another embodiment, the first air inlet 510 may also be located between the evaporator 200 and the axial flow wind wheel 330. In order to realize the air intake of the first air intake 510, the first air intake 510 may be disposed towards the evaporator 200, and cool air may enter the air intake duct 500 through the first air intake 510, and a proper setting position may be specifically selected according to practical situations.
To further limit the position of the air induction duct 500, referring to fig. 3, in the embodiment of the present invention, the air induction duct 500 may be fixedly connected to the bracket 340. For example, an installation part is provided on the outer wall of the induced draft duct 500, and the installation part is fixedly connected to the bracket 340 by a fastener such as a screw or a bolt. Of course, the connection can be realized by a buckle, or welding, and a proper scheme is selected according to actual conditions. Through with induced draft duct 500 and support 340 fixed connection, the assembly is simple, and can further improve induced draft duct 500 connection's stability, reduces induced draft duct 500 and becomes flexible the risk that drops.
Referring to fig. 3, in an embodiment of the present invention, the electronic control device 400 includes a heat sink 410, and the first air outlet 530 is disposed towards the heat sink 410. For example, the heat sink 410 may be made of aluminum alloy, brass or bronze, and the heat generated by the electric control device 400 is transferred to the heat sink 410, and most of the heat can be taken away after the cool air blown by the first air outlet 530 passes through the heat sink 410, so as to effectively reduce the temperature of the electric control device 400. The air outlet direction of the first air outlet 530 may be the same as the length direction of the heat sink 410, so as to increase the contact area between the cold air and the heat sink 410, and further increase the heat dissipation efficiency of the electronic control device 400.
With continued reference to fig. 3, in an embodiment of the present invention, the heat sink 410 may be provided with a plurality of heat sinks 410 spaced apart in the up-down direction. An air duct is formed between the adjacent heat sinks 410, and the air duct communicates with the first air outlet 530. Therefore, the cool air can enter the air duct when being blown out from the first air outlet 530, so as to more effectively take away the heat on the heat sink 410, and the plurality of heat sinks 410 can further improve the heat dissipation efficiency, thereby effectively improving the condition of the over-high temperature of the electric control device 400. It should be noted that, in other embodiments, the plurality of cooling fins 410 may be disposed at intervals along the vertical direction, may be disposed at intervals along the horizontal direction, or may be disposed at intervals along the oblique direction, and in particular, a suitable arrangement manner may be selected according to practical situations.
It is understood that the air energy water heater adopts the principle of a heat pump system, and the heat is released by a condenser in the heat pump system to heat water. The evaporator 200 and the air are also required to exchange heat to improve the heating efficiency of the condenser. That is, by increasing the temperature of the evaporator 200, the heat release amount of the condenser can be increased.
In order to improve the heat exchange efficiency of the evaporator 200, heat generated by the electronic control device 400 may be guided to the air intake cavity 113 to improve the temperature of the intake air. In order to achieve this, referring to fig. 2, 6 and 7, in the embodiment of the invention, the housing 100 includes a guiding portion 130, and the guiding portion 130 is located on a side of the electronic control device 400 facing away from the first air outlet 530. For example, the flow guiding portion 130 is a part of the housing 110, the housing 110 is annular, and the flow guiding portion 130 has an arc-shaped structure. After the cool air blown out from the first air outlet 530 passes through the electric control device 400, the temperature of the air will rise, so that hot air with a temperature higher than the ambient temperature can be formed, and then flows back into the air inlet cavity 113 under the guiding function of the guiding portion 130 and the negative pressure of the air inlet cavity 113. In another embodiment, the first air outlet 530 is offset from the second air inlet 111 along the projection of the air outlet direction of the housing 100, so that the hot air is beneficial to flow back into the air inlet cavity 113 under the action of the guiding portion 130. By increasing the temperature of the intake air, the heat exchange efficiency of the evaporator 200 is increased. The guide part 130 and the housing 110 may be integrally formed, so that manufacturing difficulty can be reduced, assembly efficiency can be improved, and production cost can be reduced.
It should be noted that, instead of integrally forming the flow guiding portion 130 and the housing 110, the flow guiding portion 130 may be separately designed into a flow guiding sheet or a flow guiding pipe. For example, the guide part 130 is a guide piece independent of the housing 110, and the guide piece is connected to the water receiving tray 120 or to the inner wall of the housing 110, and the connection manner may be welding, clamping, fastening, etc. The guide vane also has the function of guiding the hot air back to the air inlet cavity 113. It should be further noted that, in another embodiment, instead of guiding the hot air formed after passing through the electronic control device 400 back to the air inlet cavity 113, the hot air may be directly guided to the outside of the housing 110, for example, by a pipe, an exhaust fan, or the like, to blow the hot air out of the housing 110.
In the embodiment of the present invention, the air inlet area of the first air inlet 510 is S, which satisfies the following conditions: 300mm 2 ≤S≤1200mm 2 S may be 300mm, for example 2 、400mm 2 、600mm 2 、800mm 2 、1000mm 2 Etc. The air inlet area of the first air inlet 510 is mainly designed according to the heat productivity of the electronic control device 400, and is related to the air outlet speed, the air outlet temperature, the setting position of the first air inlet 510, the position of the first air outlet 530, the air outlet area of the first air outlet 530, the length of the heat sink 410, the contact area of the heat sink 410, and the heat conduction efficiency of the air outlet cavity 114.
In order to ensure the heat dissipation effect of the electronic control device 400, the larger the air intake area of the first air intake 510, the better. But is limited by other conditions, such as the hot air backflow in the above embodiment, the air intake of the first air inlet 510 needs to be controlled. For example, when the first air inlet area is larger than 1200mm 2 At this time, the air intake of the first air inlet 510 is too large, and when the cool air is blown out from the first air outlet 530, the temperature of the air is still lower than the temperature of the surrounding environment after passing through the electric control device 400, and the air flows back to the air intake cavity 113, which easily results in the air intake cavity 113The temperature is reduced, and thus the heat exchange efficiency of the evaporator 200 is affected, so that the air intake area of the first air intake 510 cannot be too large. When the first air inlet area is smaller than 300mm 2 At this time, the air intake of the first air inlet 510 is smaller, the heat dissipation of the electronic control device 400 is not obvious, the heat dissipation effect of the electronic control device 400 is poor, the temperature is too high, and the engine is easy to crash, so that the air intake area of the first air inlet 510 cannot be too small. The reasonable design of the air inlet area of the first air inlet 510 can ensure the heat dissipation effect of the electric control device 400 and improve the heat exchange efficiency of the evaporator 200.
Referring to fig. 7, in the embodiment of the present invention, the electronic control device 400 is located on a side of the evaporator 200 facing away from the air outlet cavity 114, or the electronic control device 400 is located on a side of the evaporator 200 facing away from the air outlet device 300. The electric control device 400 can be located at a position close to the inner wall of the casing 100 and is connected to the water pan 120 through a structure such as a mounting table, so that a space exists between the electric control device 400 and the water pan 120, condensed water is prevented from entering the electric control device 400, and the safety of the electric control device 400 is improved. The middle part of the shell 100 can be used for placing a compressor, namely the compressor can be positioned in the air inlet cavity 113, and heat generated by the compressor can also be in heat exchange with the evaporator 200, so that the heat exchange efficiency of the evaporator 200 is further improved. It can be appreciated that the electronic control device 400 is located at a side of the evaporator 200 away from the air outlet cavity 114, and when the hot air flows back to the air inlet cavity 113, the hot air flowing back path can be shortened, so as to reduce heat loss. And negative pressure is formed when the air inlet cavity 113 is used for air inlet, so that hot air is conveniently guided to flow back into the air inlet cavity 113. Therefore, the electric control device 400 has reasonable position layout, can improve the efficiency of hot gas backflow and reduce heat loss.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present invention.
