Description

Technical Field

[0001] The present invention relates to the technical field of electric control heat dissipation, and in particular to an electric control module component, an outdoor unit and HVAC equipment. Background Art

[0002] In the related art, the electric control module generates a lot of heat when working. In order to ensure the stable operation of the electric control module, the electric control module is usually cooled. For example, some use a heat dissipation component to connect the components of the electric control module with heat conduction. The components transfer the generated heat to the heat dissipation component, and the heat is dissipated through the heat dissipation component, thereby achieving heat dissipation of the electric control module.

[0003] However, the heights of the multiple components arranged on the electric control board of the electric control module are different. Due to the structural limitation of the heat dissipation component in the related art, the heat dissipation component can only be thermally connected with the components at the same height, and the heat dissipation effect of the components at different heights cannot be guaranteed, thus affecting the heat dissipation effect of the entire electric control module. Therefore, there is room for improvement. Summary of the invention

DETAILED DESCRIPTION

[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 10 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0057] Reference Figure 1-Figure 9The electric control module assembly 10 according to the first embodiment of the present invention includes an electric control module 20 and a heat dissipation component 30, and the heat dissipation component 30 is used to dissipate heat from the electric control module 20. The electric control module 20 includes an electric control component 21, and the electric control component 21 includes an electric control board 22 and a plurality of components 23 arranged on the electric control board 22. The heat dissipation component 30 includes at least one heat dissipating element 31, and the heat dissipating element 31 includes a heat dissipating body 32, and the heat dissipating body 32 is thermally connected to the electric control component 21, and the part of the heat dissipating element 31 thermally connected to the electric control component 21 constitutes the heat dissipating body 32. The heat generated by the electric control component 21 is transferred to the heat dissipating body 32, and the heat dissipating body 32 dissipates the heat, so that the electric control module 20 can be cooled.

[0058] The heat dissipation component 30 includes at least one heat dissipation element 31. For example, the heat dissipation component 30 may include one heat dissipation element 31. The heat dissipation component 30 may include multiple heat dissipation elements 31. The number of heat dissipation elements 31 can be set as needed. In this way, more components 23 on the electric control board 22 can be connected to the heat dissipation element 31 through thermal conduction, so that there is a larger thermal conduction area between the heat dissipation component 30 and the electric control component 21, thereby improving the heat dissipation efficiency and heat dissipation effect of the entire electric control component 21.

[0059] The heat dissipation body 32 of at least one heat sink 31 is bent to be thermally connected to at least two components 23 of different heights. The heat dissipation body 32 of a single heat sink 31 that is bent can be thermally connected to at least two components 23 of different heights. The heat dissipation body 32 of the heat sink 31 is thermally connected to the electronic control component 21. The heat generated by the electronic control component 21 during operation can be transferred to the heat dissipation body 32 of the heat sink 31, which can reduce the temperature of the electronic control component 21 and control the temperature of the electronic control component 21 within the normal temperature, thereby realizing the heat dissipation function of the heat sink 31 to ensure the stability of the operation of the electronic control module 20.

[0060] The electric control assembly 21 includes a plurality of components 23, and the components 23 of different types and sizes have different sizes in the height direction. The heat dissipation body 32 can be thermally connected to the components 23 of different heights through a bending arrangement according to the different sizes of the components 23 in the height direction, thereby ensuring that the components 23 of different heights can be well fitted with the heat dissipation element 31, improving the heat dissipation efficiency of the components 23, while ensuring the heat dissipation effect of the components 23, thereby improving the heat dissipation effect of the entire electric control module 20. In addition, the bending arrangement can reduce the space occupied by the heat dissipation body 32, ensuring the compact structure of the entire electric control module 20.

[0061] It should be explained that the height of the component 23 refers to the protruding height of the component 23 relative to the electric control board 22 .

[0062] The heat dissipation body 32 of at least one heat dissipation element 31 is bent, that is, one of the heat dissipation elements 31 in the heat dissipation component 30 may be bent, multiple heat dissipation elements 31 may be bent, or each heat dissipation element 31 in the heat dissipation component 30 may be bent.

[0063] At least two components 23 of different heights refer to two or more components 23 of different heights. By bending at least one heat sink 31, the heat sink 31 can be thermally connected to the components 23 of different heights, thereby ensuring that the components 23 of different heights can be thermally connected to the heat sink 31, thereby improving the heat dissipation efficiency of the components 23.

[0064] Optionally, a heat dissipation channel 35 for the flow of heat dissipation medium may be formed in the heat dissipation element 31 . The heat generated by the components 23 may be taken away by the flow of the heat dissipation medium, thereby improving the heat dissipation efficiency and effect.

[0065] According to the electric control module assembly 10 of the embodiment of the present invention, the heat dissipation component 30 is set so that the heat dissipation body 32 of the heat dissipation member 31 is thermally connected to the electric control assembly 21, thereby realizing heat dissipation of the electric control module 20; and the heat dissipation body 32 is set by bending, so that the same heat dissipation body 32 can be thermally connected to components 23 of different heights. In this way, the bent heat dissipation body 32 can adapt to components 23 of different heights, so that the heat dissipation body 32 can be better fitted with components 23 of different heights, thereby improving the heat dissipation effect of components 23 of different heights, thereby improving the heat dissipation effect of the entire electric control module 20.

[0066] It should be noted that the “plurality” mentioned in the present invention refers to two or more than two.

[0067] Reference Figure 2 as well as Fig. 9According to some embodiments of the present invention, the end face of the component 23 in the height direction is the device end face 231, and the heat dissipation body 32 is thermally connected to the device end face 231. Different components 23 have different sizes in the height direction, and the height positions of the device end faces 231 of components 23 at different heights are different. The heat dissipation body 32 of the heat sink 31 is arranged by bending, so that the heat dissipation body 32 of the heat sink 31 can be thermally connected to the device end faces 231 of components 23 with different heights, so that the heat dissipation body 32 of the heat sink 31 can be well fitted with the device end faces 231 of components 23 with different heights, which can ensure the heat dissipation effect of components 23 with different heights. At the same time, through this arrangement, the arrangement of the heat sink 31 inside the electric control module assembly 10 can be facilitated, and the arrangement difficulty can be reduced. In addition, the heat sink 31 can ensure that there is a large heat conduction area between the component 23 and the heat dissipation body 32 by thermally connecting with the device end face 231, thereby ensuring the heat dissipation effect of the heat sink 31 on the component 23.

[0068] Reference Figure 2 , Figure 4 as well as Fig. 9 According to some embodiments of the present invention, the bent heat dissipation body 32 includes a plurality of straight sections 321 and a connecting section 322 connected between adjacent straight sections 321, an angle is formed between the straight section 321 and the connecting section 322, and the angle formed between the straight section 321 and the connecting section 322 is an angle greater than zero, the straight section 321 is thermally connected to the device end face 231, and the heights of the components 23 corresponding to the plurality of straight sections 321 of the same heat dissipation body 32 are different. The straight section 321 of the heat dissipation body 32 is thermally connected to the device end face 231, so that the straight section 321 of the heat dissipation body 32 and the device end face 231 of the component 23 can be matched, so that the straight section 321 of the heat dissipation body 32 and the device end face 231 of the component 23 are well fitted, so that the heat conduction area between the heat dissipation body 32 and the device end face 231 of the component 23 is larger, and the heat dissipation efficiency of the component 23 can be improved.

[0069] The connecting section 322 of the heat dissipation body 32 is used to connect two adjacent straight sections 321. The two adjacent straight sections 321 can be connected to the components 23 at different heights by thermal conduction, so that the bending structure of the heat dissipation body 32 is relatively simple and easy to process and shape. Different straight sections 321 of the same heat dissipation body 32 correspond to components 23 at different heights, so the connecting section 322 connected between two adjacent straight sections 321 has an angle with the two adjacent straight sections 321. Through this setting, the heat dissipation body 32 can be connected to the components 23 at different heights by thermal conduction, and the heat dissipation body 32 has a simple structure and is convenient for production and processing.

[0070] For example, refer to Figure 2 and Figure 4The heat dissipation component 30 includes two heat dissipation members 31, namely a first heat dissipation member 31a and a first heat dissipation member 31b. The heat dissipation body 32 of the first heat dissipation member 31a includes two straight sections 321 and a connecting section 322 connected between the two straight sections 321. The two straight sections 321 correspond to components 23 of two different heights respectively.

[0071] For example, refer to Figure 8-Figure 9 The heat dissipation component 30 includes two heat dissipation members 31, namely a third heat dissipation member 31c and a fourth heat dissipation member 31d. The heat dissipation body 32 of the third heat dissipation member 31c includes three straight sections 321 and two connecting sections 322 connected between adjacent straight sections 321. The three straight sections 321 correspond to components 23 of three different heights respectively.

[0072] Reference Figure 2 as well as Fig. 9 According to some embodiments of the present invention, the angle between the straight section 321 and the connecting section 322 is 90° to 170°. For example, the angle between the straight section 321 and the connecting section 322 may be 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, etc. By setting the angle between the straight section 321 and the connecting section 322 to 90°~170°, there is a larger angle between the straight section 321 and the connecting section 322, so that the bending degree of the heat dissipation body 32 is small, which is convenient for processing and manufacturing; in addition, when a heat dissipation channel 35 for the flow of heat dissipation medium is formed in the heat dissipation element 31, when the heat dissipation medium flows through the part between the straight section 321 and the connecting section 322, if the angle between the straight section 321 and the connecting section 322 is too small, it will cause greater resistance to the flow of the heat dissipation medium. By setting the angle between the straight section 321 and the connecting section 322 to 90°~170°, the resistance of the heat dissipation medium when flowing through the part between the straight section 321 and the connecting section 322 can be reduced, and the guiding effect of the connecting section 322 can be ensured, thereby ensuring that the heat dissipation medium in the heat dissipation element 31 can flow smoothly, ensuring the heat dissipation effect of the heat dissipation element 31 on the components 23, and avoiding the occurrence of poor flow of the heat dissipation medium due to the large bending degree of the heat dissipation body 32.

[0073] Reference Figure 2 as well as Fig. 9According to some embodiments of the present invention, the number of connecting segments 322 is 1 to 4, for example, the number of connecting segments 322 can be 1, 2, 3 or 4. The connecting segment 322 is used to connect two adjacent straight segments 321, and the two adjacent straight segments 321 can be thermally connected to components 23 of different heights, thereby reducing the number of heat sinks 31 in the heat dissipation component 30, and reducing costs to a certain extent. The number of connecting segments 322 is 1 to 4, so that the number of bending times of the heat dissipation body 32 during the processing is small, which is convenient for processing and manufacturing, and reduces the difficulty of processing and forming; and when a heat dissipation channel 35 for the flow of heat dissipation medium is formed in the heat dissipation element 31, it can ensure that the heat dissipation medium in the heat dissipation element 31 can flow smoothly, avoiding the situation where the flow path of the heat dissipation body 32 is more complicated due to too many bending times, resulting in poor flow of the heat dissipation medium, and ensuring the heat dissipation effect of the heat dissipation element 31 on the components 23.

[0074] Reference Figure 2 and Figure 4 According to some embodiments of the present invention, the height difference of the components 23 corresponding to the adjacent straight sections 321 is greater than 8mm. The heights of the multiple components 23 arranged on the electric control board 22 of the electric control module 20 are usually different. For example, the height difference of adjacent components 23 can be 1mm, 3mm, 5mm, 7mm, 9mm, 12mm, 15mm, 20mm, 30mm, etc. There are also different situations for the height difference between adjacent components 23. The height difference of some adjacent components 23 is large, and the height difference of some adjacent components 23 is small. If there is a height difference between adjacent components 23, the heat dissipation body 32 is bent to adapt to the height difference between adjacent components 23. In this way, there will be too many bending positions of the heat dissipation body 32, and the length of the connecting section 322 is too small, resulting in a large resistance to the flow of the heat dissipation medium in the heat dissipation body 32, which will significantly affect the heat dissipation effect and increase the difficulty of processing and forming the heat dissipation body 32.

[0075] Based on this, the present invention bends the heat dissipation body 32 to correspond to components 23 of different heights, while taking into account the influence of bending on the flow of the heat dissipation medium and the processing difficulty. When the height difference between adjacent components 23 is greater than 8 mm, the corresponding part of the heat dissipation body 32 is bent. This can reduce the number of bending positions of a single heat dissipation body 32, so that the length of the connecting section 322 will not be too short, which can reduce the flow resistance of the heat dissipation medium in the heat dissipation body 32, and can make the heat dissipation body 32 and the components 23 fit better. Overall, it can have a better heat dissipation effect, and the processing difficulty of the heat sink 31 is relatively low.

[0076] By making the height difference of the components 23 corresponding to adjacent straight sections 321 greater than 8 mm, the connecting section 322 between the adjacent straight sections 321 can be made to have a certain length, thereby avoiding the connection section 322 being too short, which would make the angle between the connection section 322 and the straight section 321 difficult to process, thereby reducing the difficulty of processing the heat sink 31; and when a heat dissipation channel 35 for the heat dissipation medium to flow is formed in the heat sink 31, the guiding effect of the connecting section 322 can be ensured, thereby avoiding the situation where the heat dissipation medium does not flow smoothly due to the too short connection section 322, thereby ensuring the heat dissipation effect of the heat sink 31 on the components 23.

[0077] In some embodiments of the present invention, the same straight section 321 may correspond to one component 23 , and the same straight section 321 may also correspond to at least two components 23 .

[0078] For example, refer to Figure 2 and Figure 4 In some embodiments of the present invention, the same straight section 321 corresponds to at least two components 23, and the height difference of the components 23 corresponding to the same straight section 321 is less than 5mm. The heights of the multiple components 23 arranged on the electric control board 22 of the electric control module 20 are usually different. For example, the height difference of adjacent components 23 can be 1mm, 3mm, 5mm, 7mm, 9mm, 12mm, 15mm, 20mm, 30mm, etc. There are also different situations for the height difference between adjacent components 23. The height difference of some adjacent components 23 is large, and the height difference of some adjacent components 23 is small. If there is a height difference between adjacent components 23, the heat dissipation body 32 is bent to adapt to the height difference between adjacent components 23. In this way, there will be too many bending positions of the heat dissipation body 32, and the length of the connecting section 322 is too small, resulting in a large resistance in the process of the heat dissipation medium flowing in the heat dissipation body 32, which will significantly affect the heat dissipation effect and increase the difficulty of processing and forming the heat dissipation body.

[0079] Based on this, the present invention bends the heat dissipation body 32 to correspond to components 23 of different heights, and at the same time considers the influence of bending on the flow of the heat dissipation medium and the processing difficulty. When the height difference between adjacent components 23 is less than 5 mm, the corresponding part of the heat dissipation body 32 is no longer bent, and the same straight section 321 is used to correspond to adjacent components 23 with a height difference of less than 5 mm. In this way, the number of bending positions of a single heat dissipation body 32 can be reduced, the flow resistance of the heat dissipation medium in the heat dissipation body 32 can be reduced, and the heat dissipation body 32 and the components 23 can be better fitted. Overall, it can have a better heat dissipation effect, and the processing difficulty of the heat sink 31 is relatively low.

[0080] When the height difference of different components 23 corresponding to the same heat dissipation body 32 is less than 5mm, the same straight section 321 can be connected to components 23 of different heights by heat conduction, replacing the connection method of connecting components 23 of different heights with different straight sections 321, and the structure is relatively simple; and when a heat dissipation channel 35 for the flow of heat dissipation medium is formed in the heat dissipation element 31, this arrangement can make the flow path of the heat dissipation channel 35 smoother, thereby ensuring the smoothness of the flow of the heat dissipation medium. In addition, through this arrangement, the number of bends of the heat dissipation body 32 can be reduced, the structure of the heat dissipation body 32 can be made simpler, and the production and processing difficulty of the heat dissipation element 31 can be reduced.

[0081] Among them, when the same straight section 321 corresponds to adjacent components 23 with a height difference of less than 5 mm, a thermal conductive layer can be filled between the straight section 321 and the components 23 with a lower height to compensate for the height difference, thereby achieving heat dissipation of adjacent components 23 with a height difference of less than 5 mm by the same straight section 321.

[0082] According to some embodiments of the present invention, a heat-conducting layer is provided between the straight section 321 and the device end face 231 to ensure the connection and heat-conducting effect of the heat-conducting connection between the straight section 321 and the device end face 231, further ensure that the straight section 321 and the device end face 231 are well attached, reduce the interface thermal resistance between the device end face 231 and the straight section 321, and improve the heat-conducting efficiency between the two. In addition, by providing a heat-conducting layer, when the same straight section 321 corresponds to components 23 of different heights and the height difference between the different components 23 is small, the height difference between the components 23 of different heights can be compensated by filling the heat-conducting layer, so that the same heat dissipation body 32 can use the same straight section 321 to connect components 23 of different heights, so that the structure of the heat sink 31 is simpler and convenient for production and processing.

[0083] Optionally, there may be a gap between the connecting section 322 and the component 23, and the connecting section 322 and the component 23 may also be in direct contact or thermally connected. When the connecting section 322 and the component 23 are in contact or thermally connected, the heat generated by the component 23 is also transferred to the connecting section 322 for heat dissipation. When the connecting section 322 and the component 23 are thermally connected, a thermal conductive layer may be provided between the connecting section 322 and the component 23 to achieve thermal connection between the two.

[0084] Optionally, the heat-conducting layer may include one or more of heat-conducting glue, heat-conducting silicone grease, heat-conducting pad or heat-conducting metal to ensure the heat-conducting effect of the heat-conducting layer. For example, the heat-conducting layer may be heat-conducting glue, heat-conducting silicone grease, heat-conducting pad or heat-conducting metal; the heat-conducting layer may also include at least two of heat-conducting glue, heat-conducting silicone grease, heat-conducting pad and heat-conducting metal. When the heat-conducting layer includes at least two of heat-conducting glue, heat-conducting silicone grease, heat-conducting pad and heat-conducting metal, the two heat-conducting structures may be stacked along the thickness direction of the heat-conducting layer, and the two heat-conducting structures may also be mixed with each other to form a heat-conducting layer.

[0085] In some embodiments, when the height difference between adjacent components 23 is between 5 mm and 8 mm, a single component 23 can be cooled by a single heat dissipation body 32 .

[0086] Reference Figure 2-Figure 5 as well as Fig. 9 According to some embodiments of the present invention, there are multiple heat sinks 31, and the electric control assembly 21 includes component groups 24 corresponding to each heat sink 31. The heat dissipation body 32 of each heat sink 31 is thermally connected to the components 23 in the corresponding component group 24. By setting the component group 24, the spatial layout inside the electric control module assembly 10 can be regionalized and rationalized. In addition, by setting the component group 24, the components 23 of different heights can be rationally classified to facilitate the arrangement of the heat sink 31.

[0087] The component group 24 includes a first component group 241, in which the height difference between at least some of two adjacent components 23 in the first component group 241 is greater than 8 mm, and the heat dissipation body 32 thermally connected to the first component group 241 is bent. The heat dissipation body 32 thermally connected to the first component group 241 is bent so that the heat dissipation body 32 and the device end faces 231 of the components 23 at different heights in the first component group 241 can be thermally connected, thereby ensuring the heat dissipation effect of the components 23 at different heights in the first component group 241. Through this arrangement, the connecting section 322 between adjacent straight sections 321 can have a certain length, avoiding the connection section 322 being too short, which would make the angle between the connecting section 322 and the straight section 321 difficult to process. This can reduce the difficulty of processing and forming the heat sink 31. Moreover, when a heat dissipation channel 35 for the heat dissipation medium to flow is formed in the heat sink 31, the guiding effect of the connecting section 322 can be ensured, avoiding the situation where the heat dissipation medium does not flow smoothly due to the connection section 322 being too short, thereby ensuring the heat dissipation effect of the heat sink 31 on the components 23.

[0088] The height difference between at least some adjacent two components 23 in the first component group 241 is greater than 8 mm, that is, the height difference between some adjacent two components 23 may be greater than 8 mm, or the height difference between any two adjacent components 23 in the first component group 241 may be greater than 8 mm. Through this setting, the division of the area of ​​the component group 24 can be facilitated.

[0089] For example, refer to Figure 2-Figure 5 The heat dissipation component 30 includes a first heat dissipation member 31a, the electronic control component 21 includes a first component group 241, the first component group 241 includes five components 23 of two different heights, and the heat dissipation body 32 of the first heat dissipation member 31a is bent and thermally connected to the five components 23 in the first component group 241, thereby ensuring the heat dissipation effect of the components 23 of different heights.

[0090] For example, refer to Figure 8-Figure 9 The heat dissipation component 30 includes a third heat dissipation member 31c, the electronic control assembly 21 includes a first component group 241, the first component group 241 includes six components 23 of three different heights, and the heat dissipation body 32 of the third heat dissipation member 31c is bent and thermally connected to the six components 23 in the first component group 241, thereby ensuring the heat dissipation effect of the components 23 of different heights.

[0091] Reference Figure 2 as well as Fig. 9 According to some embodiments of the present invention, the component group 24 includes a second component group 242, the height difference between each two adjacent components 23 in the second component group 242 is less than 5mm, and the heat dissipation body 32 thermally connected to the second component group 242 is a straight structure. Through this arrangement, the height difference between each two adjacent components 23 in the second component group 242 is less than 5mm, and the heat dissipation body 32 thermally connected to the second component group 242 does not need to be bent, which can make the structure of the heat dissipation body 32 simpler and reduce the production and processing difficulty of the heat dissipation element 31; and when a heat dissipation channel 35 for the heat dissipation medium to flow is formed in the heat dissipation element 31, the heat dissipation body 32 with a straight structure has a better flow guiding effect, and the heat dissipation medium in the heat dissipation element 31 can flow more smoothly.

[0092] The height difference between at least some of the two adjacent components 23 in the first component group 241 is greater than 8 mm, and the height difference between every two adjacent components 23 in the second component group 242 is less than 5 mm. Through this arrangement, the division of the area of ​​the component group 24 can be facilitated, thereby facilitating the arrangement of the heat sink 31.

[0093] For example, refer to Figure 2-Figure 5The heat dissipation component 30 includes a first heat dissipation member 31b, the electronic control component 21 includes a second component group 242, the second component group 242 includes three components 23 of the same height, the heat dissipation body 32 of the first heat dissipation member 31b is a flat structure, and is thermally connected to the three components 23 in the second component group 242, thereby ensuring the heat dissipation effect of the components 23.

[0094] For example, refer to Figure 8-Figure 9 The heat dissipation component 30 includes a fourth heat dissipation member 31d, the electronic control assembly 21 includes a second component group 242, the second component group 242 includes a component 23, and the heat dissipation body 32 of the fourth heat dissipation member 31d is a straight structure, which is thermally connected to the component 23 in the second component group 242, thereby ensuring the heat dissipation effect of this component 23.

[0095] Reference Figure 2-Figure 5 as well as Figure 8-Figure 9 According to some embodiments of the present invention, there are multiple heat sinks 31, and the electronic control assembly 21 includes component groups 24 corresponding to each heat sink 31, and at least two component groups 24 have different powers or different widths, and the widths of the heat sink bodies 32 corresponding to the component groups 24 with different powers or different widths are different. The widths of the heat sink bodies 32 corresponding to the component groups 24 with different powers or widths are different. Through this setting, it can be ensured that the components 23 with different powers or widths in the component group 24 have sufficient contact areas with the corresponding heat sink bodies 32, thereby ensuring that there is sufficient heat conduction area between different components 23 and the heat sink bodies 32, so as to improve the heat dissipation efficiency of the components 23.

[0096] Optionally, the width of the heat dissipation body 32 can be the same as the width of the corresponding component group 24, or the width of the heat dissipation body 32 can be slightly larger than the width of the corresponding component group 24, ensuring that there is sufficient heat conduction area between the component 23 and the heat dissipation body 32 while controlling the width of the heat dissipation body 32, thereby avoiding the situation where the cost of the heat sink 31 is higher due to the width of the heat dissipation body 32 being larger than the width of the component group 24.

[0097] For example, refer to Figure 2-Figure 5 as well as Figure 8-Figure 9 There are two heat sinks 31 in the heat dissipation component 30, and there are two component groups 24 in the electronic control assembly 21. The widths of the two component groups 24 are different, and the widths of the heat dissipation bodies 32 respectively thermally connected to the two component groups 24 are also different.

[0098] For example, the multiple components 23 may include capacitors, common-mode inductors, fan control components for controlling the outdoor fan 12, compressor control components for controlling the compressor assembly 13, and PFC components. Among them, the fan control components, compressor control components, and PFC components have higher power than other components 23, and the temperature rises faster during operation. The heat dissipation body 32 connected thereto can be set to a larger width to increase the heat conduction area between the heat dissipation body 32 and the components 23, and improve the heat dissipation effect of the components 23. Compared with other components 23, capacitors and common-mode inductors have lower power, and the temperature rises relatively slowly during operation. The heat dissipation body 32 connected thereto can be set to a smaller width to reduce the cost of the heat sink 31.

[0099] Reference Fig. 9 According to some embodiments of the present invention, the heat dissipation body 32 is formed in a flat shape, and at least one side of the heat dissipation body 32 in the thickness direction is thermally connected to the component 23. At least one side of the heat dissipation body 32 in the thickness direction is thermally connected to the component 23, that is, one side of the heat dissipation body 32 in the thickness direction is thermally connected to the component 23, or both sides of the heat dissipation body 32 in the thickness direction are thermally connected to the component 23. The flat heat dissipation body 32 has a larger contact surface with the component 23, so that the heat conduction area between the component 23 and the heat dissipation body 32 can be greatly increased, thereby improving the heat dissipation effect of the component 23. In addition, the flat heat dissipation body 32 can greatly reduce the space occupancy rate of the heat sink 31.

[0100] Reference Figure 2 and Figure 5 According to some embodiments of the present invention, the heat dissipation body 32 is connected to the electric control board 22 by a first fastener 26. This connection method can ensure the connection effect between the heat dissipation body 32 and the electric control board 22. At the same time, the connection process is simple, which can facilitate the assembly and disassembly of the heat dissipation body 32 and the electric control board 22. Among them, the first fastener 26 can be a threaded fastener, and the heat dissipation body 32 and the electric control board 22 are threadedly connected by the first fastener, which is reliable and convenient for assembly and disassembly.

[0101] Reference Figure 1-Figure 9 According to some embodiments of the present invention, a heat dissipation channel 35 for the flow of heat dissipation medium is formed in the heat dissipation member 31. The heat dissipation medium can absorb the heat generated by the components 23 during operation by flowing in the heat dissipation channel 35, thereby realizing the heat dissipation function of the heat dissipation member 30 and achieving a better heat dissipation effect.

[0102] Reference Figure 8-Figure 9According to some embodiments of the present invention, the heat dissipation component 30 includes a medium inlet pipe 36 and a medium outlet pipe 37, and the heat dissipation channel 35 connects the medium inlet pipe 36 and the medium outlet pipe 37. The heat dissipation medium enters the heat dissipation channel 35 from the medium inlet pipe 36, absorbs the heat generated by the components 23 during operation while flowing in the heat dissipation channel 35, and then flows out from the medium outlet pipe 37. Through this arrangement, the structure is simple and the heat dissipation efficiency is high.

[0103] Reference Figure 8-Figure 9 According to some embodiments of the present invention, a plurality of heat sinks 31 are arranged in parallel. The heat sinks 31 can share the same medium inlet pipe 36 and the same medium outlet pipe 37 by being arranged in parallel, thereby reducing the number of medium inlet pipes 36 and medium outlet pipes 37 in the electric control module assembly 10, reducing production costs, and having a simple structure, which can improve space utilization. In addition, the plurality of heat sinks 31 arranged in parallel can dissipate heat more evenly for the components 23, thereby further improving the heat dissipation effect.

[0104] For example, refer to Figure 8-Figure 9 The heat dissipation component 30 includes two heat dissipation components 31, namely the third heat dissipation component 31c and the fourth heat dissipation component 31d. The two heat dissipation components 31 are arranged in parallel and share a medium inlet pipe 36 and a medium outlet pipe 37, which can reduce the number of medium inlet pipes 36 and medium outlet pipes 37, reduce production costs, and have a simple structure, which can improve space utilization. The heat dissipation medium enters the heat dissipation channel 35 of the third heat dissipation component 31c and the fourth heat dissipation component 31d from the medium inlet pipe 36, and absorbs the heat generated by the components 23 that are respectively thermally connected to the heat dissipation bodies 32 of the third heat dissipation component 31c and the fourth heat dissipation component 31d during the working process. After being collected in the medium outlet pipe 37, it flows out from the medium outlet pipe 37, thereby making the heat dissipation of the components 23 more uniform, which can further improve the heat dissipation effect of the heat dissipation component 30.

[0105] Reference Figure 8-Figure 9 According to some embodiments of the present invention, the medium inlet pipe 36 and the medium outlet pipe 37 are located on both sides of the length direction of the electric control board 22, the heat sink 31 extends along the length direction of the electric control board 22, and multiple heat sinks 31 are arranged along the width direction of the electric control board 22. Through this arrangement, the structure of the medium inlet pipe 36, the medium outlet pipe 37 and the heat dissipation channel 35 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 sink 31 extends along the length direction of the electric control board 22, and can contact more components 23 on the electric control board 22, thereby improving the heat dissipation effect of the heat dissipation component 30; and the number of heat sinks 31 can be reduced, and the length of the medium inlet pipe 36 and the medium outlet pipe 37 can be shortened.

[0106] Reference Figure 1-Figure 7According to some embodiments of the present invention, the heat sink 31 is a phase-change heat sink and includes a heat absorbing section 33 and a heat dissipating section 34. The heat dissipating medium in the heat sink 31 is suitable for circulating between the heat absorbing section 33 and the heat dissipating section 34. The heat absorbing section 33 includes a heat dissipating body 32. The heat absorbing section 33 of the heat sink 31 is used to absorb the heat generated by the components 23 during operation to achieve the heat dissipation function of the components 23. The heat dissipating section 34 of the heat sink 31 is used to dissipate the heat of the heat dissipating medium, so that the heat dissipating medium can flow to the heat dissipating section 34 again to absorb heat after the heat dissipation is completed, thereby achieving the circulation of the heat dissipating medium between the heat absorbing section 33 and the heat dissipating section 34.

[0107] During the operation of the heat sink 31, the heat dissipation medium located in the heat absorption section 33 is in a liquid state. After the liquid heat dissipation medium absorbs the heat generated during the operation of the component 23, it will be converted from liquid to gas and flow to the heat dissipation section 34 through the heat dissipation channel 35. The gaseous heat dissipation medium condenses in the heat dissipation section 34, and is converted from a high-temperature gas to a low-temperature liquid again. Finally, it flows to the heat absorption section 33 through the heat dissipation channel 35, and absorbs the heat generated during the operation of the component 23 again, and performs the next heat dissipation cycle. The heat dissipation medium circulates between the heat absorption section 33 and the heat dissipation section 34, and completes the functions of heat absorption and heat dissipation through the phase change of the heat dissipation medium in the heat dissipation channel 35, thereby realizing the function of the heat sink 31 to circulate and dissipate heat for the component 23.

[0108] Reference Figure 1-Figure 2 According to some embodiments of the present invention, the electric control module 20 includes an electric control box body 25, the electric control component 21 is arranged in the electric control box body 25, the heat absorption section 33 is located in the electric control box body 25, and the heat dissipation section 34 is located outside the electric control box body 25. The electric control box body 25 can isolate and protect the electric control module 20 and the heat dissipation component 30 inside it, prevent dust outside the electric control box body 25 from entering the inside of the electric control box body 25, and to a certain extent, improve the service life of the internal parts of the electric control box body 25. In addition, the heat dissipation section 34 is arranged outside the electric control box body 25, so that the heat of the heat dissipation medium located in the heat dissipation section 34 can be dissipated in time, thereby ensuring the heat dissipation effect of the next heat dissipation cycle.

[0109] Reference Figure 1-Figure 9The outdoor unit 100 according to the second embodiment of the present invention comprises an outdoor housing 11, an outdoor heat exchanger, an outdoor fan 12, a compressor assembly 13 and an electric control module assembly 10. The outdoor heat exchanger and the outdoor fan 12 are arranged in the outdoor housing 11, the compressor assembly 13 is arranged in the outdoor housing 11, and the electric control module assembly 10 is arranged in the outdoor housing 11 and is the electric control module assembly 10 according to the first embodiment of the present invention. A heat dissipation component 30 is arranged inside the electric control module assembly 10, and the heat dissipation component 30 can improve the heat dissipation effect of the components 23 inside the electric control module 20, and can avoid the problem of the electric control module assembly 10 failing due to excessive temperature, thereby ensuring the stability of the operation of the outdoor unit 100.

[0110] According to the outdoor unit 100 of the embodiment of the present invention, by setting the above-mentioned electric control module assembly 10, the heat dissipation component 30 of the electric control module assembly 10 dissipates heat for the electric control module 20, and at the same time can ensure the heat dissipation effect of components 23 of different heights, thereby improving the stability of the electric control module 20, and further ensuring the reliability of the operation of the outdoor unit 100.

[0111] Reference Figure 1-Figure 7 According to some embodiments of the present invention, the refrigerant circulation system of the outdoor unit 100 includes a cooling part 15 for dissipating heat from the electric control module 20. During the flow of the refrigerant in the refrigerant circulation system, the refrigerant can flow through the cooling part 15. The cooling part 15 is thermally connected to the heat dissipation component 30 or at least part of the cooling part 15 constitutes the heat dissipation component 30. The refrigerant circulation system of the outdoor unit 100 includes a cooling part 15 for dissipating heat from the electric control module 20. Through this configuration, the refrigerant in the refrigerant circulation system can be used to take away the heat generated by the electric control module 20.

[0112] The cooling part 15 is thermally connected to the heat dissipation component 30 , and the heat generated by the electronic control module 20 is transferred to the cooling part 15 through the heat dissipation component 30 , and then the heat is taken away by the refrigerant flowing through the cooling part 15 , thereby achieving indirect heat dissipation and cooling of the electronic control module 20 by the refrigerant.

[0113] At least part of the cooling unit 15 constitutes the heat dissipation component 30, that is, part of the cooling unit 15 may constitute the heat dissipation component 30, or the cooling unit 15 may all belong to the heat dissipation component 30. The heat generated by the electric control module 20 may be directly transferred to the cooling unit 15, and the heat may be taken away by the refrigerant flowing through the cooling unit 15, so that the refrigerant may indirectly dissipate heat and cool the electric control module 20. This arrangement has a simple structure, and the heat conducting member 38 connected between the cooling unit 15 and the electric control module 20 may be omitted, and the cooling unit 15 may better absorb the heat generated by the electric control module 20.

[0114] Reference Figure 1According to some embodiments of the present invention, the outdoor unit 100 further includes a water heat exchange component, which includes a water heat exchanger 14. The water heat exchanger 14 has a water flow channel and a refrigerant channel for mutual heat exchange. The water flow channel and the refrigerant channel in the water heat exchanger 14 can realize the heat exchange function of the water heat exchanger 14 by mutual heat exchange. After the refrigerant in the refrigerant circulation system enters the refrigerant channel of the water heat exchanger 14, 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 14 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.

[0115] The water heat exchanger 14 has a first refrigerant inlet and outlet 141 and a second refrigerant inlet and outlet 142 both connected to the refrigerant channel, and the refrigerant flows into the refrigerant channel from one of the first refrigerant inlet and outlet 141 and the second refrigerant inlet and outlet 142 and flows out of the refrigerant channel from the other of the first refrigerant inlet and outlet 141 and the second refrigerant inlet and outlet 142. 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 15 is connected between the second refrigerant inlet and outlet 142 and the first heat exchange inlet and outlet.

[0116] For example, when the outdoor heat exchanger acts as an evaporator and the water heat exchanger 14 acts as a condenser, the refrigerant discharged from the compressor assembly 13 flows into the refrigerant channel of the water heat exchanger 14 through the first refrigerant inlet and outlet 141, and flows out from the second refrigerant inlet and outlet 142. Part of the refrigerant flowing out of the water heat exchanger 14 can flow through the cooling unit 15 and take away the heat generated by the electronic control module 20. The refrigerant flowing out of the cooling unit 15 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 14, 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 15. At this time, the refrigerant flowing into the cooling unit 15 has a lower temperature after heat exchange by the water heat exchanger 14. The refrigerant flowing through the cooling unit 15 can achieve the heat dissipation function of the electronic control module 20. 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 14 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 20, which can reduce the risk of condensation caused by the use of refrigerant to dissipate heat from the electric control module 20. In addition, by using the refrigerant after passing through the water heat exchanger 14 to dissipate heat from the electric control module 20, the heat exchange performance of the water heat exchanger 14 can be prioritized to ensure that the indoor heat exchange demand is met.

[0117] When the outdoor heat exchanger acts as a condenser and the water heat exchanger 14 acts as an evaporator, the refrigerant discharged from the compressor assembly 13 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. Part of the refrigerant flowing out of the outdoor heat exchanger can flow through the cooling unit 15 and take away the heat generated by the electronic control module 20. The refrigerant flowing out of the cooling unit 15 flows into the water heat exchanger 14 from the second refrigerant inlet and outlet 142, and flows out of the water heat exchanger 14 from the first refrigerant inlet and outlet 141, 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 unit 15. At this time, the temperature of the refrigerant flowing into the cooling unit 15 is relatively low after heat exchange by the outdoor heat exchanger. The refrigerant flowing through the cooling unit 15 can achieve the heat dissipation function of the electronic control module 20. 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 14 can achieve heat dissipation for the electronic control module 20 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 20.

[0118] The cooling part 15 is connected between the outdoor heat exchanger and the water heat exchanger 14. Since the refrigerant between the outdoor heat exchanger and the water heat exchanger 14 is used to dissipate the heat of the electronic control module 20, the temperature of the refrigerant flowing between the water heat exchanger 14 and the outdoor heat exchanger can meet the heat dissipation and cooling effect of the electronic control module 20. At the same time, since the refrigerant temperature of this part is higher than the temperature of the refrigerant in the return air pipe part, the condensation phenomenon caused by using the refrigerant to cool the electronic control module 20 can be reduced or avoided, thereby improving the safety of the whole machine.

[0119] Reference Figure 1-Figure 2 According to some embodiments of the present invention, the cooling part 15 is thermally connected to the heat dissipation component 30, the heat dissipation element 31 is a phase change heat dissipation element and includes a heat absorption section 33 and a heat dissipation section 34, the heat dissipation medium in the heat dissipation element 31 is suitable for circulating between the heat absorption section 33 and the heat dissipation section 34, the heat absorption section 33 includes a heat dissipation body 32, and the cooling part 15 is thermally connected to the heat dissipation section 34. The heat absorption section 33 of the heat dissipation element 31 is used to absorb the heat generated by the components 23 during operation, so as to realize the heat dissipation function of the heat dissipation element 31 to the components 23, and the heat dissipation section 34 of the heat dissipation element 31 is thermally connected to the cooling part 15 to realize the heat dissipation function of the cooling part 15 to the heat dissipation medium. The heat dissipation body 32 of the absorption section is thermally connected to the component 23 for absorbing the heat generated by the component 23. The cooling part 15 is thermally connected to the heat dissipation section 34 for absorbing the heat of the heat dissipation medium in the heat dissipation section 34. Through this arrangement, the heat dissipation medium can undergo phase change and circulate in the heat absorption section 33 and the heat dissipation section 34, thereby realizing the function of the heat sink 31 to circulate the heat of the component 23.

[0120] During the operation of the heat sink 31, the heat dissipation medium located in the heat absorption section 33 is in a liquid state. After the liquid heat dissipation medium absorbs the heat generated during the operation of the component 23, it will be converted from liquid to gas and flow to the heat dissipation section 34 through the heat dissipation channel 35. The cooling part 15 is thermally connected to the heat dissipation section 34, absorbing the heat of the heat dissipation medium located at the heat dissipation section 34, so that the gaseous heat dissipation medium condenses in the heat dissipation section 34, and is converted from a high-temperature gaseous state to a low-temperature liquid state again, and finally flows back to the heat absorption section 33 through the heat dissipation channel 35, and absorbs the heat generated during the operation of the component 23 again, and performs the next heat dissipation cycle.

The heat dissipation component 30 is used to dissipate heat from the electric control module 20 and includes two heat sinks 31, and the two heat sinks 31 are respectively a first heat sink 31a and a first heat sink 31b. The heat sink 31 includes a heat sink body 32 , which is thermally connected to the electronic control assembly 21 . The heat sink body 32 of the first heat sink 31 a is bent to be thermally connected to components 23 of two different heights.

[0133] Among them, the end face of the component 23 in the height direction is the device end face 231, the heat dissipation body 32 is thermally connected to the device end face 231, the heat dissipation body 32 of the first heat dissipation member 31a includes two straight sections 321 and a connecting section 322 connected between adjacent straight sections 321, the number of connecting sections 322 is one, and there is an angle between the straight sections 321 and the connecting sections 322, and the angle is 90° to 170°.

[0134] The electric control assembly 21 includes a component group 24 corresponding to each heat sink 31, and the heat sink body 32 of each heat sink 31 is thermally connected to the component 23 in the corresponding component group 24. The component group 24 includes a first component group 241, and the height difference between at least some of the two adjacent components 23 in the first component group 241 is greater than 8mm. The first component group 241 is thermally connected to the heat sink body 32 of the first heat sink 31a. The component group 24 also includes a second component group 242, and the height difference between each two adjacent components 23 in the second component group 242 is less than 5mm. The second component group 242 is thermally connected to the heat sink body 32 of the first heat sink 31b. The first component group 241 and the second component group 242 have different widths, and the widths of the heat sink bodies 32 corresponding to the component groups 24 with different widths are different. The heat dissipation bodies 32 of the first heat dissipation members 31 a and 31 b are formed in a flat shape. One side of the heat dissipation bodies 32 in the thickness direction is thermally connected to the components 23 . The heat dissipation bodies 32 are connected to the electric control board 22 via the first fasteners 26 .

[0135] The first heat sink 31a and the first heat sink 31b are phase change heat sink elements and include a heat absorption section 33 and a heat dissipation section 34, wherein the heat dissipation section 34 of the heat dissipation component 30 is located in the fan cavity. The heat dissipation medium in the heat sink 31 is suitable for circulating between the heat absorption section 33 and the heat dissipation section 34, and the heat absorption section 33 includes a heat dissipation body 32. The electric control component 21 is arranged in the electric control box body 25, the heat absorption section 33 is located in the electric control box body 25, and the heat dissipation section 34 is located outside the electric control box body 25. During the operation of the heat sink 31, the heat dissipation medium located in the heat absorption section 33 is in a liquid state. After the liquid heat dissipation medium absorbs the heat generated during the operation of the component 23, it will be converted from liquid to gas and flow to the heat dissipation section 34 through the heat dissipation channel 35. The cooling part 15 is thermally connected to the heat dissipation section 34, absorbing the heat of the heat dissipation medium located at the heat dissipation section 34, so that the gaseous heat dissipation medium condenses in the heat dissipation section 34, and is converted from a high-temperature gaseous state to a low-temperature liquid state again, and finally flows back to the heat absorption section 33 through the heat dissipation channel 35, and absorbs the heat generated during the operation of the component 23 again, and performs the next heat dissipation cycle.

The heat dissipation section 34 is connected to the heat-conducting member 38 by welding or by a second fastener, and the cooling part 15 is connected to the heat-conducting member 38 by welding.

[0137] The water heat exchange assembly includes a water heat exchanger 14, which has a water flow channel and a refrigerant channel for mutual heat exchange, as well as a water inlet 17 and a water outlet 18. The water flow channel and the refrigerant channel in the water heat exchanger 14 can realize the heat exchange function of the water heat exchanger 14 by mutual heat exchange. After the refrigerant in the refrigerant circulation system enters the refrigerant channel of the water heat exchanger 14, 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 17, flows out of the water heat exchanger 14 after heat exchange, and then flows out from the water outlet 18, 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.

The cooling unit 15 is connected between the second refrigerant inlet and outlet 142 and the first heat exchange inlet and outlet.

[0139] The cooling unit 15 is connected between the outdoor heat exchanger and the water heat exchanger 14. Since the refrigerant between the outdoor heat exchanger and the water heat exchanger 14 is used to dissipate the heat of the electric control module 20, the temperature of the refrigerant flowing between the water heat exchanger 14 and the outdoor heat exchanger can meet the heat dissipation and cooling effect of the electric control module 20. 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 20 can be reduced or avoided, thereby improving the safety of the whole machine. Among them, a throttling component 16 is provided between the outdoor heat exchanger and the water heat exchanger 14 to adjust the flow of the refrigerant between the outdoor heat exchanger and the water heat exchanger 14.

[0140] The heat dissipation component 30 can enable the heat dissipation body 32 of the heat dissipation element 31 to be thermally connected to the electronic control component 21, thereby achieving heat dissipation of the electronic control module 20; and, the heat dissipation body 32 of the first heat dissipation element 31a is bent so that the same heat dissipation body 32 can be thermally connected to components 23 of different heights. In this way, the bent heat dissipation body 32 can adapt to components 23 of different heights, so that the heat dissipation body 32 can be better fitted with components 23 of different heights, thereby improving the heat dissipation effect of components 23 of different heights, thereby improving the heat dissipation effect of the entire electronic control module 20.

[0141] Refer to the following Figure 8-Figure 9 , describing the outdoor unit 100 according to other embodiments of the present invention.

[0143] The heat dissipation component 30 of the electric control module assembly 10 in this embodiment includes a third heat dissipation member 31c and a fourth heat dissipation member 31d. The heat dissipation body 32 of the third heat dissipation member 31c includes three straight sections 321 and two connecting sections 322 connected between adjacent straight sections 321. The fourth heat dissipation member 31d is a straight structure. The first component group 241 is thermally connected to the heat dissipation body 32 of the third heat dissipation member 31c, and the height difference between at least some of the adjacent two components 23 in the first component group 241 is greater than 8mm; the second component group 242 is thermally connected to the fourth heat dissipation member 31d, and the height difference between each adjacent two components 23 in the second component group 242 is less than 5mm.

[0144] In addition, a heat dissipation channel 35 for the heat dissipation medium to flow is formed in the heat dissipation element 31, and at least part of the cooling portion 15 constitutes the heat dissipation component 30. The heat dissipation component 30 includes a medium inlet pipe 36 and a medium outlet pipe 37, and the heat dissipation channel 35 connects the medium inlet pipe 36 and the medium outlet pipe 37.

[0145] The heat dissipation body 32 of the third heat sink 31c is bent so that the same heat dissipation body 32 can be thermally connected to components 23 at different heights. The bent heat dissipation body 32 can adapt to components 23 at different heights, so that the heat dissipation body 32 can fit better with components 23 at different heights, thereby improving the heat dissipation effect of components 23 at different heights, thereby improving the heat dissipation effect of the entire electronic control module 20.
