[0055] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0056] The electric control module assembly 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0057] Reference Figure 1-Figure 11 According to the first embodiment of the present invention, the electric control module assembly 100 includes an electric control module 10 and a heat dissipation component 20. The electric control module 10 includes an electric control assembly 11. The electric control assembly 11 includes an electric control board 12 and a plurality of components 13 disposed on the electric control board 12. The heat dissipation component 20 is used to dissipate heat from the electric control module 10 and includes at least one heat dissipation element 21. The heat dissipation element 21 includes a heat dissipation body 23. The heat dissipation body 23 of at least one heat dissipation element 21 is located on the outer peripheral side of the components 13. By providing the heat dissipation component 20, the heat generated by the electric control module 10 during the working process can be dissipated through the heat dissipation component 20, so that the temperature of the electric control assembly 11 is controlled within the normal operating temperature to ensure the stability of the operation of the electric control module 10.

[0058] The heat dissipation component 20 includes at least one heat dissipation element 21. The heat dissipation body 23 of at least one heat dissipation element 21 is arranged on the outer peripheral side of the component 13. The component 13 exchanges heat with the heat dissipation body 23 arranged on the outer peripheral side to realize the heat dissipation function of the heat dissipation component 20 on the component 13. Since the peripheral side area of ​​the component 13 is relatively large, the area of ​​heat transfer between the component 13 and the heat dissipation component 20 can be increased, thereby improving the heat dissipation effect of multiple components 13 in the electric control component 11 and improving the heat dissipation effect of the entire electric control module 10. In addition, the heat dissipation body 23 of at least one heat dissipation element 21 is arranged on the outer peripheral side of the component 13, which can make full use of the space on the outer peripheral side of the component 13, so that the arrangement of the heat dissipation component 20 and the component 13 is more compact, thereby making the structure of the electric control module assembly 100 more compact, which is conducive to reducing the volume of the electric control module assembly 100.

[0059] The heat dissipation component 20 is used to dissipate heat for the electric control module 10 and includes at least one heat dissipation element 21 , that is, the heat dissipation component 20 may include one heat dissipation element 21 or multiple heat dissipation elements 21 to ensure the heat dissipation effect of the heat dissipation component 20 on the electric control module 10 .

[0060] The heat dissipation body 23 of at least one heat sink 21 is located on the peripheral side of the component 13, that is, the heat dissipation body 23 of one heat sink 21 can be located on the peripheral side of the component 13, or the heat dissipation bodies 23 of multiple heat sinks 21 can be located on the peripheral side of the component 13, so as to ensure the heat dissipation effect of the heat dissipation component 20 on the electronic control module 10.

[0061] Optionally, the heat sink 21 located on the peripheral side of the component 13 can have a certain gap between it and the component 13 to maintain a safe distance. The component 13 can exchange heat with the heat dissipation body 23 of the heat sink 21 arranged on the peripheral side through thermal radiation, thereby controlling the temperature of the component 13 within the normal operating temperature.

[0062] Optionally, the heat sink 21 located on the peripheral side of the component 13 can be in direct contact with the component 13, and the component 13 is directly thermally connected to the heat dissipation body 23 of the heat sink 21 arranged on the peripheral side and heat is exchanged, thereby controlling the temperature of the component 13 within the normal operating temperature.

[0063] Optionally, a heat conducting layer may be provided between the heat sink 21 located on the outer peripheral side of the component 13 and the component 13, and a heat conducting connection is performed through the heat conducting layer. When the component 13 is not insulated and sealed, the heat conducting layer may also play a role of insulation protection. For example, the heat conducting layer may be made of thermally conductive glue, thermally conductive silicone grease, or thermally conductive pads, which can ensure the heat transfer effect between the component 13 and the heat sink 21 and also play a role of insulation protection.

[0064] According to the electric control module assembly 100 of the embodiment of the present invention, a heat dissipation component 20 including at least one heat dissipation member 21 is provided, so that the heat dissipation body 23 of at least one heat dissipation member 21 is located on the peripheral side of the component 13. Since the peripheral side area of ​​the component 13 is relatively large, the heat transfer area between the component 13 and the heat dissipation component 20 can be increased, thereby improving the heat dissipation effect of the component 13, thereby improving the heat dissipation effect of the entire electric control module 10.

[0065] It should be noted that the term “plurality” in the present invention refers to two or more.

[0066] Reference Figure 3-Figure 5 and Figure 9-11 According to some embodiments of the present invention, the heat sink 21 whose heat dissipation body 23 is located on the outer peripheral side of the component 13 is the first heat sink 22, and the heat dissipation body 23 of at least part of the first heat sink 22 extends in a non-linear manner, for example, the heat dissipation body 23 of part of the first heat sink 22 may extend in a non-linear manner, or the heat dissipation body 23 of each first heat sink 22 may extend in a non-linear manner. By making the heat dissipation body 23 of at least part of the first heat sink 22 extend in a non-linear manner, the heat dissipation body 23 of the non-linearly extending first heat sink 22 can increase the area of ​​heat transfer with the component 13, thereby improving the heat dissipation effect. In addition, when the number of components 13 in the electric control module 10 is large, the heat sink 21 extending in a non-linear manner can better match the arrangement of the components 13 in the electric control module 10, thereby making full use of the internal space of the electric control module assembly 100, so that the arrangement of the heat dissipation component 20 and the components 13 is more compact.

[0067] Reference Figure 3-Figure 5 and Figure 9-11 According to some embodiments of the present invention, at least part of the heat dissipation body 23 of the first heat dissipation member 22 extends circumferentially along the component 13. At least part of the heat dissipation body 23 of the first heat dissipation member 22 extends circumferentially along the component 13, that is, part of the heat dissipation body 23 of the first heat dissipation member 22 extends circumferentially along the component 13, or the heat dissipation body 23 of the first heat dissipation member 22 extends circumferentially along the component 13.

[0068] Through this arrangement, the first heat sink 22 extending circumferentially along the component 13 can increase the heat transfer area between the heat dissipation body 23 of the first heat sink 22 and the component 13, thereby improving the heat dissipation efficiency of the first heat sink 22 to a certain extent, thereby ensuring the heat dissipation effect of the first heat sink 22 on the component 13.

[0069] It should be explained that the height of the component 13 refers to the protruding height dimension of the component 13 relative to the electric control board 12 , and the circumferential direction of the component 13 refers to the direction perpendicular to the height direction of the component 13 .

[0070] Reference Figure 3 , Figure 5 , Fig. 9 as well as Fig.11 According to some embodiments of the present invention, the heat dissipation body 23 of the first heat dissipation member 22 includes a bending portion 24 or a plurality of bending portions 24 arranged at intervals along the extension direction of the first heat dissipation member 22, and the bending portion 24 includes a plurality of bending segments 25 connected in sequence along the extension direction of the first heat dissipation member 22, and an angle is formed between two adjacent bending segments 25. By providing the bending portion 24, the heat transfer area between the heat dissipation body 23 and the component 13 can be increased, thereby ensuring the heat dissipation effect of the heat dissipation body 23 on the component 13. The bending segments 25 are connected along the extension direction of the first heat dissipation member 22 to form the bending portion 24, and the structure is relatively simple, which can facilitate the processing and manufacturing of the bending portion 24 to a certain extent.

[0071] It should be explained that, if two adjacent bending segments 25 are both straight structures, the angle between the two adjacent bending segments 25 refers to the angle between the straight lines where the two straight structures are located; if at least part of the two bending segments 25 include arc structures, the angle between the two adjacent bending segments refers to the angle between the tangent of any point at the arc structure of one of the bending segments 25 and the tangent of any point at the arc structure of the other bending segment 25; if one of the two bending segments 25 is a straight structure and at least part of the other bending segment 25 includes an arc structure, the angle between the two adjacent bending segments 25 refers to the angle between the straight line where the straight structure is located and the tangent of any point at the arc structure of the other bending segment 25.

[0072] For example, refer to Figure 3 and Figure 5 The first heat sink 22 includes three bending portions 24 arranged at intervals along the extension direction of the first heat sink 22 . Through this arrangement, the heat dissipation effect of the heat dissipation body 23 on the component 13 can be improved.

[0073] For example, refer to Figure 3 and Figure 5 The bending portion 24 includes three bending sections 25 connected in sequence along the extension direction of the first heat sink 22, and an angle is formed between two adjacent bending sections 25. Through this arrangement, the structure of the bending portion 24 can be made simpler and convenient for production and processing.

[0074] Reference Figure 3 , Figure 5 , Fig. 9 as well as Fig.11According to some embodiments of the present invention, the angle between two adjacent bending segments 25 ranges from 90 to 170°. For example, the angle between two adjacent bending segments 25 can be 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, etc. By setting the angle between two adjacent bending sections 25 to 90° to 170°, a larger angle can be formed between the two bending sections 25, so that the bending degree of the bending portion 24 is smaller, which is convenient for processing and manufacturing; in addition, when a heat dissipation channel 27 for the flow of heat dissipation medium is formed in the heat sink 21, when the heat dissipation medium flows through the part between the two bending sections 25, if the angle between the two bending sections 25 is too small, it will cause greater resistance to the flow of the heat dissipation medium. By setting the angle between the two bending sections 25 to 90° to 170°, the resistance of the heat dissipation medium when flowing through the part between the two bending sections 25 can be reduced, and the guiding effect of the bending section 25 can be ensured, thereby ensuring that the heat dissipation medium in the heat sink 21 can flow smoothly, ensuring the heat dissipation effect of the heat sink 21 on the components 13, and avoiding the occurrence of poor flow of the heat dissipation medium.

[0075] Reference Figure 3 , Figure 5 , Fig. 9 as well as Fig.11 According to some embodiments of the present invention, the first heat sink 22 further includes a non-bending portion 26 extending in a straight line, the bending section 25 of the bending section 24 connected to the non-bending portion 26 is a first bending section 25a, and the angle between the non-bending portion 26 and the first bending section 25a is in the range of 90 to 170°. By providing the non-bending portion 26, the processing difficulty and production cost of the first heat sink 22 can be reduced to a certain extent. In addition, when a heat dissipation channel 27 for the heat dissipation medium to flow is formed in the heat dissipation element 21, when the heat dissipation medium flows through the portion between the non-bending portion 26 and the first bending section 25a, if the angle between the non-bending portion 26 and the first bending section 25a is too small, it will cause greater resistance to the flow of the heat dissipation medium. By setting the angle between the non-bending portion 26 and the first bending section 25a to 90° to 170°, the resistance of the heat dissipation medium flowing through the portion between the non-bending portion 26 and the first bending section 25a can be reduced, and the guiding effect of the first heat dissipation element 22 can be ensured, thereby ensuring that the heat dissipation medium in the heat dissipation element 21 can flow smoothly, ensuring the heat dissipation effect of the heat dissipation element 21 on the components 13, and avoiding the occurrence of poor flow of the heat dissipation medium. At the same time, by setting the non-bending portion 26, it can further facilitate the flow of the heat dissipation medium in the heat dissipation channel 27. In addition, the non-bending portion 26 can also be used to dissipate heat for components with lower heat generation, or to dissipate heat for densely arranged component areas.

[0076] It should be explained that, if the first bending section 25a is a straight structure, the angle between the non-bending portion 26 and the first bending section 25a refers to the angle between the non-bending portion 26 and the straight line where the first bending section 25a is located; if at least part of the first bending section 25a includes an arc structure, the angle between the non-bending portion 26 and the first bending section 25a refers to the angle between the straight line where the non-bending section 25 is located and the tangent of any point of the arc structure of the first bending section 25a.

[0077] Reference Figure 3 , Figure 5 , Fig. 9 as well as Fig.11 According to some embodiments of the present invention, the heat sink 21 whose heat dissipation body 23 is located on the outer periphery of the component 13 is the first heat sink 22, and the heat dissipation body 23 of the first heat sink 22 is located on the outer periphery of multiple components 13. Through this arrangement, the same first heat sink 22 can improve the heat dissipation effect of multiple components 13, thereby reducing the number of first heat sinks 22, reducing production costs to a certain extent, and at the same time, reducing the space occupancy rate of the heat dissipation component 20 in the electric control module assembly 100, thereby improving the space utilization rate of the electric control module assembly 100.

[0078] Reference Figure 3 , Figure 5 , Fig. 9 as well as Fig.11 According to some embodiments of the present invention, the heat sink 21 whose heat dissipation body 23 is located on the outer peripheral side of the component 13 is the first heat sink 22, at least part of the multiple components 13 are arranged along the length direction of the electric control board 12 and constitute the component group 11, and the heat dissipation body 23 of the first heat sink 22 extends along the circumference of the components 13 of the component group 11. By setting the component group 11, the spatial layout inside the electric control module assembly 100 can be regionalized and rationalized, and at the same time, it can facilitate the arrangement of the first heat sink 22 and make full use of the internal space of the electric control module assembly 100. The heat dissipation body 23 of the first heat sink 22 extends along the circumference of the components 13 of the component group 11, which can ensure the heat dissipation effect of the multiple components 13 in the component group 11, thereby improving the heat dissipation effect of the entire electric control module 10.

[0079] At least part of the multiple components 13 are arranged along the length direction of the electric control board 12 to form the component group 11, that is, some of the multiple components 13 can be arranged along the length direction of the electric control board 12 to form the component group 11, or all of the multiple components 13 can be arranged along the length direction of the electric control board 12 to form the component group 11.

[0080] For example, refer to Figure 3The seven components 13 are arranged along the length direction of the electric control board 12 and constitute a component group 11. The heat dissipation body 23 of the first heat sink 22 extends along the circumference of the seven components 13 in the component group 11 to ensure the heat dissipation effect of each component 13 in the component group 11.

[0081] Reference Fig. 9 and Fig.11 According to some embodiments of the present invention, the heat sink 21 of the heat dissipation body 23 located on the outer peripheral side of the component 13 is the first heat sink 22, at least part of the multiple components 13 are arranged along the length direction of the electric control board 12 and constitute the component group 11, and the first heat sink 22 is provided on both sides of the component group 11 along the width direction of the electric control board 12. By providing the component group 11, the spatial layout inside the electric control module assembly 100 can be regionalized and rationalized, and the arrangement of the first heat sink 22 can be facilitated, and the internal space of the electric control module assembly 100 can be fully utilized. By providing the first heat sink 22 on both sides of the component group 11 along the width direction of the electric control board 12, the area of ​​heat transfer between the heat dissipation body 23 and the outer peripheral side of the component 13 can be increased, thereby improving the heat dissipation effect of the component 13, thereby improving the heat dissipation effect of the entire electric control module 10.

[0083] For example, refer to Figure 8 Seven components 13 are arranged along the length direction of the electronic control board 12 to form a component group 11. A first heat sink 22 is provided on both sides of the component group 11 along the width direction of the electronic control board 12. The two first heat sinks 22 can ensure the heat dissipation effect of each component 13 in the component group 11.

[0084] Reference Figure 3-Figure 5 and Figure 9-11According to some embodiments of the present invention, the heat sink 21 whose heat dissipation body 23 is located on the outer peripheral side of the component 13 is the first heat sink 22, the peripheral side surface of the component 13 is the device side 131, and the heat dissipation body 23 of the first heat sink 22 is thermally connected to the device side 131. Through this arrangement, the heat generated by the component 13 thermally connected to the heat dissipation body 23 of the first heat sink 22 during operation can be heat exchanged with the heat dissipation body 23 of the first heat sink 22 at the device side 131, thereby controlling the temperature of the component 13 within the normal operating temperature to ensure the stability of the operation of the component 13. The device side 131 of the component 13 has a relatively large area, so the heat conduction area between the heat dissipation body 23 and the component 13 can be increased, thereby improving the heat dissipation effect of the first heat sink 22 on the component 13.

[0085] Optionally, the heat dissipation body 23 of the first heat dissipation element 22 is thermally connected to the device side 131, and the heat dissipation body 23 of the first heat dissipation element 22 can be thermally connected to the device side 131 directly, or the heat dissipation body 23 of the first heat dissipation element 22 can be thermally connected to the device side 131 through a thermal conductive layer.

The end surface of the component 13 in the height direction is the device end surface 132, and the heat dissipation body 23 of the second heat sink 30 is thermally connected to the device end surface 132.

[0089] Optionally, the second heat sink 30 can be a bent setting. For example, when the second heat sink 30 is thermally connected or thermally contacted with multiple components 23, the second heat sink 30 can be bent in the height direction of the components 23, so that the second heat sink 30 can be directly or indirectly thermally connected to the device end faces 132 of multiple components with different heights.

The number of components 13 thermally connected to the heat element 30 is one, the device end face 132 of this component 13 is a straight structure and the area of ​​the device end face 132 is larger than the area of ​​the peripheral side. By providing a second heat sink 30 thermally connected to the device end face 132, the thermal conduction area between the component 13 and the heat dissipation component 20 can be increased, thereby improving the heat dissipation effect of this component 13. In addition, the second heat sink 30 thermally connected to the device end face 132 has a relatively simple structure, which can facilitate the processing and production of the second heat sink 30.

In addition, the plurality of heat sinks 21 arranged in parallel can dissipate heat more evenly for the components 13, thereby further improving the heat dissipation effect.

[0103] For example, refer to Figure 3 and Figure 5The heat dissipation component 20 includes two heat dissipation elements 21, which are arranged in parallel to improve the heat dissipation effect of the components 13. At the same time, the structure is simple and the space utilization rate can be improved. The heat dissipation medium enters the heat dissipation channels 27 of the two heat dissipation elements 21 from the medium inlet pipe 28, absorbs the heat of the components 13 that are respectively heat-transferred with the heat dissipation bodies 23 of the two heat dissipation elements 21 during the flow process, and then flows out from the medium outlet pipe 29 after being collected at the medium outlet pipe 29, so that the heat dissipation of the components 13 is more uniform, which can further improve the heat dissipation effect of the heat dissipation component 20.

[0104] For example, refer to Fig. 9 and Fig.11 The heat dissipation component 20 includes three heat dissipation elements 21, which are arranged in parallel to improve the heat dissipation effect of the components 13.

[0105] Reference Figure 3-Figure 5 and Figure 9-11 According to some embodiments of the present invention, the medium inlet pipe 28 and the medium outlet pipe 29 are located in the length direction of the electric control board 12 (refer to Figure 3 and Figure 8 The heat sink 21 extends along the length direction of the electric control board 12, and the heat sink 21 extends along the width direction of the electric control board 12 (refer to Figure 3 and Figure 8 e2 direction). Through this arrangement, the structure of the medium inlet pipe 28, the medium outlet pipe 29 and the heat dissipation channel 27 is simple, and the internal space of the battery module assembly can be fully utilized, and the layout is more reasonable. In addition, the heat dissipation element 21 extends along the length direction of the electric control board 12, and can contact more components 13 on the electric control board 12, thereby improving the heat dissipation effect of the heat dissipation component 20; and the number of heat dissipation elements 21 can be reduced, and the length of the medium inlet pipe 28 and the medium outlet pipe 29 can be shortened.

[0109] Reference Figure 1-Figure 12 According to some embodiments of the present invention, the heat sink 21 is a phase-change heat sink and includes a heat absorbing section and a heat dissipating section. The heat dissipating medium in the heat sink 21 is suitable for circulating between the heat absorbing section and the heat dissipating section. The heat absorbing section includes the heat dissipating body 23. The heat absorbing section of the heat sink 21 is used to absorb the heat generated by the component 13 during operation to achieve the heat dissipation function of the component 13. The heat dissipating section of the heat sink 21 is used for heat dissipation of the heat dissipating medium, so that the heat dissipating medium can flow to the heat dissipating section again to absorb heat after the heat dissipation is completed, thereby achieving the circulation of the heat dissipating medium between the heat absorbing section and the heat dissipating section.

[0110] During the operation of the heat sink 21, the heat dissipation medium in the heat absorption section is in a liquid state. After the liquid heat dissipation medium absorbs the heat generated during the operation of the component 13, it will be converted from liquid to gas and flow to the heat dissipation section through the heat dissipation channel 27. The gaseous heat dissipation medium condenses in the heat dissipation section and is converted from high-temperature gas to low-temperature liquid again. Finally, it flows to the heat absorption section through the heat dissipation channel 27 to absorb the heat generated during the operation of the component 13 again and perform the next heat dissipation cycle. The heat dissipation medium circulates between the heat absorption section and the heat dissipation section, and completes the functions of heat absorption and heat dissipation through the phase change of the heat dissipation medium in the heat dissipation channel 27, thereby realizing the function of the heat sink 21 to circulate and dissipate heat for the component 13.

[0111] Reference Figure 1-Figure 12The outdoor unit 101 according to the second embodiment of the present invention comprises an outdoor housing 40, an outdoor heat exchanger, an outdoor fan 41, a compressor assembly 42 and an electric control module assembly 100. The outdoor heat exchanger, the outdoor fan 41, the compressor assembly 42 and the electric control module assembly 100 are all arranged in the outdoor housing 40, and the electric control module assembly 100 is the electric control module assembly 100 according to the first embodiment of the present invention. During the operation of the outdoor unit 101, the temperature of the electric control module 10 rises. By providing a heat dissipation component 20 in the electric control module assembly 100, the heat generated by the electric control module 10 during the operation process can be dissipated through the heat dissipation component 20, thereby controlling the temperature of the electric control assembly 11 within the normal operating temperature to ensure the stability of the operation of the electric control module 10.

[0112] According to the outdoor unit 101 of the embodiment of the present invention, a heat dissipation component 20 including at least one heat dissipation element 21 is provided, so that the heat dissipation body 23 of at least one heat dissipation element 21 is located on the peripheral side of the component 13. Since the peripheral side area of ​​the component 13 is relatively large, the heat transfer area between the component 13 and the heat dissipation component 20 can be increased, thereby improving the heat dissipation effect of the component 13, thereby improving the heat dissipation effect of the entire electronic control module 10.

[0113] Reference Fig.12 According to some embodiments of the present invention, the refrigerant circulation system of the outdoor unit 101 includes a cooling part 47 for dissipating heat from the electric control module 10, and the cooling part 47 is thermally connected to the heat dissipation component 20 or at least a part of the cooling part 47 constitutes the heat dissipation component 20. The refrigerant circulation system of the outdoor unit 101 includes a cooling part 47 for dissipating heat from the electric control module 10. Through this configuration, the refrigerant in the refrigerant circulation system can be used to take away the heat generated by the electric control module 10.

[0114] The cooling part 47 is thermally connected to the heat dissipation component 20. The heat generated by the electronic control module 10 is transferred to the cooling part 47 through the heat dissipation component 20, and then the heat is taken away by the refrigerant flowing through the cooling part 47, thereby realizing indirect heat dissipation and cooling of the electronic control module 10 by the refrigerant.

[0115] At least part of the cooling part 47 constitutes the heat dissipation component 20, that is, part of the cooling part 47 may constitute the heat dissipation component 20, or the cooling part 47 may all belong to the heat dissipation component 20. The heat generated by the electric control module 10 may be directly transferred to the cooling part 47, and the heat may be taken away by the refrigerant flowing through the cooling part 47, so that the refrigerant may indirectly dissipate heat and cool the electric control module 10. This arrangement has a simple structure, and the heat conducting member connected between the cooling part 47 and the electric control module 10 may be omitted, and the cooling part 47 may better absorb the heat generated by the electric control module 10.

[0116] Reference Fig.12According to some embodiments of the present invention, the outdoor unit 101 further includes a water heat exchange component, the water heat exchange component includes a water heat exchanger 43, the water heat exchanger 43 has a water flow channel and a refrigerant channel for mutual heat exchange, the water heat exchanger 43 has a refrigerant inlet and a refrigerant outlet both connected to the refrigerant channel, and the cooling unit 47 is connected between the refrigerant outlet and the inlet of the outdoor heat exchanger. The water flow channel and the refrigerant channel in the water heat exchanger 43 can realize the heat exchange function of the water heat exchanger 43 by mutual heat exchange. After the refrigerant in the refrigerant circulation system enters the refrigerant channel of the water heat exchanger 43, the water in the water flow channel exchanges heat with the refrigerant in the refrigerant channel. After the water in the water flow channel flows out of the water heat exchanger 43 after heat exchange, the temperature of the water can be changed. The water adjusted to a preset temperature can be introduced into the room to exchange heat with domestic water or introduced into the indoor heat exchanger of the indoor unit to adjust the indoor air temperature.

[0117] Optionally, the water channel heat exchanger 43 may be a plate heat exchanger.

[0118] The water heat exchanger 43 has a first refrigerant inlet and outlet 431 and a second refrigerant inlet and outlet 432 both connected to the refrigerant channel, and the refrigerant flows into the refrigerant channel from one of the first refrigerant inlet and outlet 431 and flows out of the refrigerant channel from the other of the first refrigerant inlet and outlet 431 and the second refrigerant inlet and outlet 432. The outdoor heat exchanger has a first heat exchange inlet and outlet and a second heat exchange inlet and outlet, and the refrigerant flows into the outdoor heat exchanger from one of the first heat exchange inlet and outlet and flows out of the outdoor heat exchanger from the other of the first heat exchange inlet and outlet and the second heat exchange inlet and outlet. The cooling unit 47 is connected between the second refrigerant inlet and outlet 432 and the first heat exchange inlet and outlet.

[0119] For example, when the outdoor heat exchanger acts as an evaporator and the water heat exchanger 43 acts as a condenser, the refrigerant discharged from the compressor assembly 42 flows into the refrigerant channel of the water heat exchanger 43 through the first refrigerant inlet and outlet 431, and flows out from the second refrigerant inlet and outlet 432. The refrigerant flowing out of the water heat exchanger 43 can flow through the cooling unit 47 and take away the heat generated by the electronic control module 10. The refrigerant flowing out of the cooling unit 47 flows into the outdoor heat exchanger from the first heat exchange inlet and outlet, and flows out of the outdoor heat exchanger from the second heat exchange inlet and outlet, and returns to the compressor to continue the compression cycle. After the refrigerant in the refrigerant circulation system enters the refrigerant channel of the water heat exchanger 43, the water in the water flow channel exchanges heat with the refrigerant in the refrigerant channel. After the heat exchange is completed, the refrigerant flows through the cooling unit 47. At this time, the refrigerant flowing into the cooling unit 47 has a lower temperature after heat exchange in the water heat exchanger 43. The refrigerant flowing through the cooling unit 47 can achieve the heat dissipation function of the electronic control module 10. Moreover, relative to the refrigerant temperature of the return air pipe in the refrigerant circulation system, the temperature of the refrigerant after passing through the water heat exchanger 43 and before flowing into the outdoor heat exchanger is higher than the refrigerant temperature of the return air pipe while satisfying the heat dissipation of the electric control module 10, which can reduce the risk of condensation caused by the use of refrigerant to dissipate heat from the electric control module 10. In addition, by using the refrigerant after passing through the water heat exchanger 43 to dissipate heat from the electric control module 10, the heat exchange performance of the water heat exchanger 43 can be prioritized to ensure that the indoor heat exchange demand is met.

[0120] When the outdoor heat exchanger acts as a condenser and the water heat exchanger 43 acts as an evaporator, the refrigerant discharged from the compressor assembly 42 flows into the outdoor heat exchanger through the second heat exchange inlet and outlet, and flows out from the first heat exchange inlet and outlet. The refrigerant flowing out of the outdoor heat exchanger can flow through the cooling part 47 and take away the heat generated by the electronic control module 10. The refrigerant flowing out of the cooling part 47 flows into the water heat exchanger 43 from the second refrigerant inlet and outlet 432, and flows out of the water heat exchanger 43 from the first refrigerant inlet and outlet 431, and returns to the compressor to continue the compression cycle. The refrigerant in the refrigerant circulation system enters the outdoor heat exchanger for heat exchange. After the heat exchange is completed, the refrigerant flows through the cooling part 47. At this time, the temperature of the refrigerant flowing into the cooling part 47 is relatively low after heat exchange by the outdoor heat exchanger. The refrigerant flowing through the cooling part 47 can achieve the heat dissipation function of the electronic control module 10. Furthermore, relative to the refrigerant temperature of the return air pipe portion of the refrigerant circulation system, the refrigerant that flows through the outdoor heat exchanger and before flowing into the water heat exchanger 43 can achieve heat dissipation for the electronic control module 10 while having a temperature that is higher than the refrigerant temperature of the return air pipe portion, thereby reducing the risk of condensation caused by using the refrigerant to dissipate heat for the electronic control module 10.

Since the outer peripheral side area of ​​the component 13 is relatively large, the heat transfer area between the component 13 and the heat dissipation component 20 can be increased, thereby improving the heat dissipation effect of the component 13, thereby improving the heat dissipation effect of the entire electronic control module 10.

[0130] The water heat exchange component includes a water heat exchanger 43, which includes a water inlet 44 and a water outlet 45. The water heat exchanger 43 also has a water flow channel and a refrigerant channel for mutual heat exchange. After the refrigerant in the refrigerant circulation system enters the refrigerant channel of the water heat exchanger 43, the water in the water flow channel exchanges heat with the refrigerant in the refrigerant channel. The water in the water flow channel enters from the water inlet 44, flows out of the water heat exchanger 43 after heat exchange, and then flows out from the water outlet 45, which can change the temperature of the water. The water adjusted to the preset temperature can be introduced into the room to provide domestic water or introduced into the indoor heat exchanger of the indoor unit to adjust the indoor air temperature.

[0131] The water heat exchanger 43 has a first refrigerant inlet and outlet 431 and a second refrigerant inlet and outlet 432 both connected to the refrigerant channel, and the refrigerant flows into the refrigerant channel from one of the first refrigerant inlet and outlet 431 and flows out of the refrigerant channel from the other of the first refrigerant inlet and outlet 431 and the second refrigerant inlet and outlet 432.

The cooling unit 47 is connected between the second refrigerant inlet and outlet 432 and the first heat exchange inlet and outlet.

[0132] The cooling unit 47 is connected between the outdoor heat exchanger and the water heat exchanger 43. Since the refrigerant between the outdoor heat exchanger and the water heat exchanger 43 is used to dissipate the heat of the electric control module 10, the temperature of the refrigerant flowing between the water heat exchanger 43 and the outdoor heat exchanger can meet the heat dissipation and cooling effect of the electric control module 10. At the same time, since the temperature of the refrigerant in this part is higher than the temperature of the refrigerant in the return air pipe part, the condensation phenomenon caused by the use of the refrigerant to cool the electric control module 10 can be reduced or avoided, thereby improving the safety of the whole machine. Among them, a throttling component 46 is provided between the outdoor heat exchanger and the water heat exchanger 43 to adjust the flow of the refrigerant between the outdoor heat exchanger and the water heat exchanger 43.

[0133] The refrigerant circulation system includes a connecting pipe 48 and a cooling bypass 49 connected between the refrigerant channel of the water heat exchanger 43 and the heat exchanger. The cooling bypass 49 and a part of the connecting pipe 48 are connected in parallel, and a part of the cooling bypass 49 constitutes a cooling part 47. The refrigerant in the connecting pipe 48 of the refrigerant system is used to ensure the indoor heat exchange performance to achieve the temperature regulation function; the refrigerant in the cooling part 47 of the cooling bypass 49 is used to meet the cooling demand of the electric control module 10 and realize the heat dissipation function of the electric control module 10. By setting at least a part of the outlet section of the main pipe in parallel with the cooling bypass 49, the performance of the outdoor unit 101 can be guaranteed while completing the heat dissipation function of the electric control module 10.

[0134] The outdoor unit 101 is provided with a heat dissipation component 20 including two heat dissipation members 21, so that the heat dissipation body 23 of the first heat dissipation member 22 is located on the peripheral side of the component 13. Since the peripheral side area of ​​the component 13 is relatively large, the heat transfer area between the component 13 and the heat dissipation component 20 can be increased, thereby improving the heat dissipation effect of the component 13, thereby improving the heat dissipation effect of the entire electronic control module 10.

[0135] Refer to the following Figure 7-Figure 12 , describing an electric control module assembly 100 according to other embodiments of the present invention.

[0136] Reference Figure 7-Figure 12 , in this embodiment, with Figure 1-Figure 6 The difference of the electric control module assembly 100 is that the heat dissipation component 20 includes three heat dissipation elements 21, namely two first heat dissipation elements 22 and one second heat dissipation element 30, and the two first heat dissipation elements 22 are provided with a bending portion, and the bending portion includes three bending sections.

[0137] In addition, two first heat sinks 22 are arranged on both sides of the component group 11 along the width direction of the electric control board 12, and the two first heat sinks 22 and one second heat sink 30 are connected in parallel. The two first heat sinks 22 are located on the outer peripheral side of the component 13 and are arranged on both sides along the width direction of the electric control board 12, respectively, which can increase the heat transfer area between the component 13 and the heat dissipation component 20, improve the heat dissipation effect of the component 13, and thus improve the heat dissipation effect of the entire electric control module 10.
