[0063] 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.

[0064] The electric control module assembly 10 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0065] Reference Figure 1-Figure 12 Referring to the electric control module assembly 10 according to the first embodiment of the present invention, it includes an electric control module 20 and a heat dissipation component 30. The electric control module 20 includes an electric control box body 24 and an electric control component 21 disposed in the electric control box body 24, and the electric control component 21 includes an electric control board 22 and a plurality of components 23 disposed on the electric control board 22; the heat dissipation component 30 is used to dissipate heat from the electric control module 20.

[0066] An insulating structure is provided in the electric control box body 24 , and the insulating structure covers the outer surfaces of the plurality of components 23 to isolate the components 23 from the air.

[0067] For example, refer to Figure 5 and Fig.10 The electric control module 20 includes an electric control box body 24 and an electric control component 21 arranged in the electric control box body 24. The electric control component 21 includes an electric control board 22 and a plurality of components 23 arranged in the electric control board 22. An isolation structure is provided in the electric control box body 24. The isolation structure covers the outer surfaces of the plurality of components 23 to isolate the plurality of components 23 from the air.

[0068] During the operation of the electric control module 20, the components 23 in the electric control assembly 21 will generate heat, causing the temperature of the electric control module 20 to gradually increase. By providing a heat dissipation component 30, the heat dissipation component 30 can exchange heat with the electric control module 20 to achieve a cooling effect on the electric control module 20, thereby controlling the temperature of the electric control module 20 within a normal temperature to ensure the stability of the operation of the electric control module 20.

[0069] Furthermore, by providing an isolation structure, the isolation structure covers the outer surfaces of the multiple components 23 of the electronic control assembly 21, so that the components 23 can be isolated from the air. Therefore, during the process of heat dissipation and cooling of the electronic control module 20 by the heat dissipation component 30, the components 23 will not come into contact with the outside air to cause condensation, which can avoid condensation on the components 23, and can improve the reliability, stability and safety of the electronic control module 20, thereby improving the reliability, stability and safety of the entire machine.

[0070] It should be noted that the outer surface of the component 23 includes the outer surface of the body of the component 23 and / or the outer surface of the pin. That is, the outer surface of the component 23 may include the outer surface of the body of the component 23, may include the outer surface of the pin of the component 23, or may include both the outer surface of the body of the component 23 and the outer surface of the pin of the component 23.

[0071] According to the electric control module assembly 10 of the embodiment of the present invention, by providing the heat dissipation component 30, the electric control module 20 can be cooled, and by providing the isolation structure and making the isolation structure cover the outer surface of the component 23, the component 23 can be isolated from the air, so that condensation on the component 23 of the electric control module 20 can be avoided, thereby improving the reliability, stability and safety of the electric control module 20. In addition, when there are flammable and explosive gases in the environment where the electric control module 20 is located, by providing the isolation structure and making the isolation structure cover the outer surface of the component 23, the safety hazard of ignition and explosion caused by the contact between the flammable and explosive gas and the component 23 can be eliminated, and at the same time, it can also enhance the vibration resistance of the electric control module 20, prevent the component 23 from detaching, buffer and protect the component 23, and prevent dust.

[0072] For example, in order to eliminate the safety hazard of ignition and explosion caused by contact between flammable and explosive gases and components 23 in the electronic control module 20, it is generally necessary to seal the electronic control box body 24 by setting a sealing structure or a seal to ensure the sealing of the electronic control box body 24. By setting an isolation structure in the electronic control box body 24 and the isolation structure covering the outer surface of the component 23, the safety hazard of ignition and explosion caused by contact between flammable and explosive gases and components 23 can be eliminated. At the same time, the requirements for the sealing of the electronic control box body 24 can be reduced, and the setting of parts such as seals can be reduced, thereby reducing the difficulty of production and processing to a certain extent and reducing costs.

[0073] For example, the electronic control module 20 may be the electronic control module 20 of the outdoor unit 100. If the refrigerant circulation system of the outdoor unit 100 uses a flammable refrigerant and the refrigerant circulation system leaks due to a malfunction, flammable and explosive gases will exist in the environment of the electronic control module 20. There is a safety hazard of ignition and explosion caused by contact with flammable and explosive gases in the components 23 in the electronic control module 20. By providing an isolation structure in the electronic control box body 24 and the isolation structure covering the outer surface of the component 23, the outer surface of the component 23 can be isolated from the air, thereby eliminating the safety hazard of ignition and explosion. At the same time, it can also enhance the vibration resistance of the electronic control module 20, prevent the component 23 from detaching, cushion and protect the component 23, and prevent dust.

[0074] It should be noted that the term “plurality” in the present invention refers to two or more.

[0075] Reference Figure 3-Figure 12According to some embodiments of the present invention, the isolation structure is a glue-filled structure. The potting glue used in the glue-filled structure is fluid before solidification, so it can fully contact the outer surface of the component 23, so that the isolation structure formed after the glue filling is better coated on the outside of the component 23, and can ensure the isolation effect of the component 23 from the air, so that the component 23 is better isolated from the air, and condensation is avoided due to cooling of the component 23. In addition, the glue-filled structure can improve the overall structural strength of the electric control module assembly 10, enhance the vibration resistance, and can play a role in buffering and protecting the component 23.

[0076] Reference Figure 3-Figure 12 According to some embodiments of the present invention, part of the heat dissipation component 30 is located in the electric control box body 24 and is thermally connected to the electric control component 21. The space defined by the electric control box body 24, the electric control component 21 and the heat dissipation component 30 is filled with an insulating structure to connect the electric control component 21 and the heat dissipation component 30 as a whole. In addition, an insulating structure may also be provided outside the space defined by the electric control box body 24, the electric control component 21 and the heat dissipation component 30 to ensure the covering effect of the insulating structure on the outer surface of the component 23. Part of the heat dissipation component 30 is thermally connected to the electric control component 21. The heat generated by the electric control component 21 during operation can be transferred to the heat dissipation component 30, so that the heat dissipation function of the heat dissipation component 30 on the electric control component 21 can be realized, the temperature of the electric control component 21 can be reduced, and the stability of the operation of the electric control module 20 can be ensured. The insulating structure connects the electronic control component 21 and the heat dissipation component 30 as a whole. This setting can realize the fixing effect of the insulating structure on the electronic control component 21 and the heat dissipation component 30, improve the overall structural strength of the electronic control module assembly 10, and at the same time, the heat dissipation component 30 connected as a whole with the electronic control component 21 has a better heat dissipation effect.

[0077] Reference Figure 4-Figure 6 and Figures 9 to 11 According to some embodiments of the present invention, the inner wall of the electric control box body 24 or the electric control board 22 is provided with a first limiting structure 25 for limiting the heat dissipation component 30. This arrangement can achieve the limiting effect of the electric control box body 24 on the heat dissipation component 30, ensure the stability of the position of the heat dissipation component 30, and thus ensure the heat dissipation effect of the heat dissipation component 30 on the electric control component 21.

[0078] For example, refer to Figure 6 The inner wall of the electric control box body 24 is formed with three limiting protrusions at three different positions, and the three limiting protrusions are all first limiting structures 25. The heat dissipation component 30 can be provided with limiting notches respectively matched with the three limiting protrusions of the inner wall, and the limiting protrusions of the inner wall cooperate with the limiting notches to achieve the limiting effect of the first limiting structure 25 on the heat dissipation component 30. In addition, this arrangement can facilitate the assembly of the heat dissipation component 30 and the electric control box body 24.

[0079] Reference Figure 4-Figure 7 and Figure 10-12 According to some embodiments of the present invention, the electric control board 22 has a first side 221 and a second side 222 that are arranged opposite to each other along the thickness direction of the electric control board 22, a filling space is defined between the first side 221 of the electric control board 22 and the electric control box body 24, at least some of the components 23 are arranged on the first side 221 of the electric control board 22 and are located in the filling space, and the filling space is filled with an isolation structure. At least some of the components 23 are arranged on the first side 221 of the electric control board 22 and are located in the filling space, that is, some of the components 23 may be arranged on the first side 221 of the electric control board 22 and are located in the filling space, or all of the components 23 may be arranged on the first side 221 of the electric control board 22 and are located in the filling space.

[0080] By providing an insulating structure in the filling space, the insulating effect of the insulating structure on the components 23 can be ensured, thereby preventing the components 23 from contacting the external air and generating condensation. In addition, the components 23 are all located on the first side 221 of the electronic control board 22, which can facilitate the glue filling operation of the filling space and reduce the material used in the insulating structure.

[0081] Reference Figure 3-Figure 12 According to some embodiments of the present invention, part of the heat dissipation component 30 is located in the filling space and is thermally connected to the component 23. The heat dissipation component 30 and the component 23 can be thermally connected in a variety of ways. For example, the heat dissipation component 30 located inside the filling space can be directly thermally connected to the component 23, and a thermal conductive layer can be provided between the heat dissipation component 30 and the outer surface of the component 23, and the heat dissipation component 30 and the component 23 are thermally connected through the thermal conductive layer. The heat dissipation component 30 and the component 23 are thermally connected through the thermal conductive layer, which can ensure the heat dissipation effect of the heat dissipation component 30 located in the filling space on the component 23 also located in the filling space. At the same time, the isolation structure in the filling space can isolate the heat dissipation component 30 and the component 23 located in the filling space from the external air, thereby avoiding condensation during the heat dissipation process.

[0082] Reference Figure 3-Figure 12 According to some embodiments of the present invention, an insulating structure is filled between the outer edge of the electric control board 22 and the inner wall of the electric control box body 24. By filling the insulating structure, it is possible to prevent external air from entering the electric control assembly 21 from between the outer edge of the electric control board 22 and the inner wall of the electric control box body 24, and the insulating effect of the insulating structure on the components 23 can be ensured, thereby better preventing condensation from forming on the components 23 during the heat dissipation process.

[0083] Reference Figure 3-Figure 12According to some embodiments of the present invention, the surface of the second side 222 of the electric control board 22 is the back of the board, and the insulating structure is flush with the back of the board or the insulating structure protrudes from the back of the board and covers the back of the board. The insulating structure is flush with the back of the board, which can ensure the insulating effect of the insulating structure on the components 23 arranged on the electric control board 22, thereby preventing the components 23 from contacting with the external air and generating condensation during the heat dissipation process; the insulating structure protrudes from the back of the board and covers the back of the board, and this setting can ensure the insulating effect of the insulating structure on the components 23, and at the same time, the back of the board of the electric control board 22 can be isolated from the air through the insulating structure, thereby preventing condensation from being generated on the back of the circuit board. For example, through this setting, the pins on the back of the circuit board can also be covered in the insulating structure, thereby preventing the pins from contacting with the external air and generating condensation during the heat dissipation process. At the same time, if the back panel surface is also provided with components, the insulating structure is made to protrude from the back of the board and cover the back of the board, which can ensure the insulating effect of the insulating structure on the components 23 arranged on the electric control board 22, improve the overall structural strength, and play a better buffering and protective role for the components 23.

By providing the contoured structure, the space occupancy rate of the filling space can be reduced to a large extent, and the space utilization rate inside the electric control module assembly 10 can be improved. At the same time, this setting can reduce the material used for the isolation structure, and can reduce the production cost to a certain extent.

By setting the second side 222 of the electric control board 22 as the glue-filling side, in the process of glue-filling the filling space, the direction of the electric control box body 24 is adjusted so that the second side 222 of the electric control board 22 faces upward, and the potting glue is poured from the second side 222 of the electric control board 22 to the filling space. Under the action of gravity, the potting glue flows from the second side 222 of the electric control board 22 to the lowest point of the filling space, until the entire filling space is filled, so that the outer surfaces of the multiple components 23 located inside the filling space can be covered, so that the components 23 are isolated from the air, and condensation of the components 23 due to cooling is prevented.

[0087] Reference Figure 3-Figure 12 According to some embodiments of the present invention, the electric control box body 24 includes a first box body 241 and a second box body 242 that are independently formed, the electric control component 21 is arranged in the first box body 241, and the first side 221 of the electric control board 22 faces the first box body 241 and defines a filling space between the first box body 241. Through this arrangement, after the operation of injecting glue into the filling space through the second side 222 of the electric control board 22 is completed, the electric control box body 24 is formed by connecting the second box body 242 with the first box body 241, which has a reasonable structure and is easy to operate.

[0088] In addition, after the first box body 241 and the second box body 242 are connected, the direction of the second box body 242 can be adjusted so that the second side 222 of the electric control board 22 faces upward, and glue is poured into the filling space through the second box body 242. Under the action of gravity, the potting glue flows from top to bottom from one side of the second box body 242 to the lowest point of the filling space until the entire filling space is filled. The operation is simple and the sealing effect is good. For example, a glue pouring hole connected to the filling space can be set in the second box body 242 to facilitate the glue pouring operation.

[0089] Reference Figure 6 as well as Fig.11 According to some embodiments of the present invention, a second limiting structure 26 for limiting the position of the electric control board 22 and a first fixing column 28 for fixing the electric control board 22 are formed on the inner wall of the first box body 241. During the assembly process of the electric control board 22 with the first box body 241, the second limiting structure 26 can facilitate the positioning of the electric control board 22 and the first box body 241. After the positioning is completed, the electric control board 22 and the first box body 241 can be connected and fixed by the first fixing column 28. The assembly process is simple. At the same time, the stability of the position of the electric control board 22 can be ensured, thereby facilitating the glue filling operation.

[0090] For example, refer to Figure 6 as well as Fig.11 Two limiting protrusions are formed on the inner wall edge of the first box body 241, and both limiting protrusions are second limiting structures 26.

After the electric control board 22 and the electric control box body 24 are positioned, the connection and fixation with the electric control box body 24 are completed through the five first fixing columns 28. The first fixing columns 28 can connect the electric control board 22 and the electric control box body 24 at five different positions, thereby ensuring the connection effect between the electric control board 22 and the electric control box body 24, and also making the connection process simpler. Optionally, the connection and fixation of the electric control box body 24 and the electric control board 22 can be completed by the cooperation of fasteners and the first fixing columns 28.

[0092] Reference Figure 3-Figure 12 According to some embodiments of the present invention, there is a gap between the outer edge of the electric control board 22 and the inner wall of the first box body 241, and at least part of the gap constitutes the glue filling port 44, and the glue filling port 44 is connected to the filling space. There is a gap between the outer edge of the electric control board 22 and the inner wall of the first box body 241, and at least part of the gap constitutes the glue filling port 44, that is, part of the gap may constitute the glue filling port 44, or the entire gap may constitute the glue filling port 44. By providing the glue filling port 44, the glue filling operation can be performed through the glue filling port 44 at the gap between the outer edge of the electric control board 22 and the inner wall of the first box body 241. This setting makes the structure of the glue filling port 44 simple, and the glue filling port 44 can facilitate the glue filling operation.

[0093] After the electric control board 22 and the heat dissipation component 30 are assembled, they are inverted into the first box body 241 and assembled with the first box body 241, and then the direction of the first box body 241 is adjusted so that the second side 222 of the electric control board 22 faces upward, and glue is poured into the filling space through the glue pouring port 44 on the second side 222 of the electric control board 22. Under the action of gravity, the potting glue flows from top to bottom from the second side 222 of the electric control board 22 to the lowest point of the filling space until the entire filling space is filled, so that the outer surfaces of the multiple components 23 located inside the filling space can be covered, so that the components 23 are isolated from the air. The operation of pouring glue into the filling space through the glue pouring port 44 is simple, and the glue pouring efficiency can be improved to a certain extent. In addition, the glue pouring condition can be observed through the glue pouring port 44 to avoid overflow caused by excessive potting glue.

[0094] Reference Figure 4 and Fig. 9 According to some embodiments of the present invention, a first glue injection hole 45 communicating with the filling space is formed on the electric control board 22. By providing the first glue injection hole 45, during the glue injection operation, glue can be injected into the filling space through the first glue injection hole 45 on the second side 222 of the electric control board 22, which has a simple structure and convenient operation. At the same time, the first glue injection hole 45 can also play an observation role. During the glue injection operation, the glue injection condition in the filling space can be observed through the first glue injection hole 45.

[0095] After the electric control board 22 and the heat dissipation component 30 are assembled, they are inverted into the first box body 241 and assembled with the first box body 241. The direction of the first box body 241 is adjusted so that the second side 222 of the electric control board 22 faces upward, and the filling space is filled with glue through the first glue filling hole 45 of the second side 222 of the electric control board 22. The potting glue flows from the second side 222 of the electric control board 22 to the lowest point of the filling space under the action of gravity from top to bottom until the entire filling space is filled, so that the outer surfaces of the multiple components 23 located inside the filling space can be covered, so that the components 23 are isolated from the air. The filling space is filled with glue through the first glue filling hole 45, which is simple to operate and can observe the glue filling situation through the first glue filling hole 45 to avoid overflow caused by excessive potting glue.

[0096] For example, refer to Figure 4 as well as Fig. 9 In the process of pouring glue into the filling space from the second side 222 of the electric control board 22, you can choose to pour glue into the filling space through the glue pouring port 44 formed by the gap around the inner wall of the electric control board 22 and the first box body 241; you can choose to pour glue into the filling space through the first glue pouring hole 45 on the electric control board 22; you can also choose to pour glue into the filling space through the glue pouring port 44 and the first glue pouring hole 45 at the same time.

[0097] Reference Figure 4 and Fig. 9 According to some embodiments of the present invention, the equivalent diameter of the first glue filling hole 45 is greater than 10 mm. Through this setting, it is possible to ensure that the glue filling operation is performed through the first glue filling hole 45. When the glue filling glue flows into the filling space through the first glue filling hole 45, the glue filling glue can flow smoothly, providing sufficient operating space for the glue filling operation. At the same time, the equivalent diameter of the first glue filling hole 45 is greater than 10 mm, so that the first glue filling hole 45 can play an observation role. When performing the glue filling operation, the glue filling situation in the filling space can be observed through the first glue filling hole 45. In addition, this setting can improve the glue filling efficiency to a certain extent.

[0098] Reference Figure 4 and Fig. 9 , the first glue injection hole 45 is located in the middle of the electric control board 22. With this arrangement, the potting glue can enter the filling space from the middle of the electric control board 22, which can make the flow path of the potting glue more reasonable, so that the potting glue injected into the filling space can be more evenly filled in the filling space, so that the components 23 located in the filling space are better covered by the isolation structure formed after the potting glue.

[0099] Reference Figure 4-Figure 6 and Figure 9-11According to some embodiments of the present invention, a second fixing column 29 connected to the second box body 242 is provided in the first box body 241, the surface of the second side 222 of the electric control board 22 is the back of the board, and the second fixing column 29 is located on the outer peripheral side of the electric control board 22 and protrudes from the back of the board. Through this arrangement, the first box body 241 and the second box body 242 can be connected and fixed by the second fixing column 29 to form the electric control box body 24, and the connection process is simple and the connection effect is good.

[0100] After the electric control board 22 and the heat dissipation component 30 are assembled, they are inverted into the first box body 241 and assembled with the first box body 241. Then, the direction of the first box body 241 is adjusted so that the second side 222 of the electric control board 22 faces upward, and glue is poured into the filling space through the second side 222 of the electric control board 22. By arranging the second fixing column 29 on the outer peripheral side of the electric control board 22 and protruding from the back side of the board, it is possible to avoid the situation where the sealing glue blocks the second fixing column 29 during the glue pouring process, thereby ensuring the connection effect of the second fixing column 29.

[0101] For example, refer to Figure 6 as well as Fig.11 The inner wall of the first box body 241 is provided with four second fixing columns 29 at different positions, and the four fixing columns can connect and fix the first box body 241 and the second box body 242 at four different positions, thereby ensuring the connection effect. Optionally, the connection and fixation of the first box body 241 and the second box body 242 can be completed by the cooperation of the fastener and the second fixing column 29.

[0102] Reference Figure 3 and Figure 8 According to some embodiments of the present invention, the isolation structure is a glue-filling structure, and the glue-filling side of the filling space is located at the first side 221 of the electric control board 22. The portion of the electric control box body 24 located at the first side 221 of the electric control board 22 is formed with a second glue-filling hole. When the first side 221 of the electric control board 22 faces upward, the second glue-filling hole is located at the highest position of the electric control box body 24. Through this arrangement, after the electric control board 22 and the heat dissipation component 30 are assembled, they are buckled into the first box body 241 and the assembly with the first box body 241 is completed. Then, the position of the electric control box body 24 is adjusted so that the first side 221 of the electric control board 22 faces upward, and glue is poured into the filling space through the second glue-filling hole located in the electric control box body 24. The potting glue can flow from the highest point of the electric control box body 24 to the filling space until the entire filling space is filled. When the glue is poured in this way, the first side 221 of the electric control board 22 is the glue-filling side. This arrangement can ensure that the flow path of the potting compound is relatively reasonable, and at the same time, can ensure that the potting compound can fill the entire filling space, thereby ensuring that all components 23 in the filling space are covered by the isolation structure formed after potting, thereby ensuring the isolation effect of the isolation structure.

[0103] Reference Figure 3-Figure 12According to some embodiments of the present invention, the isolation structure is a glue pouring structure, and the heat dissipation component 30 is led out from the glue pouring side of the electric control box body 24. If the heat dissipation component 30 is led out from other positions on the glue pouring side of the non-electric control box body 24, corresponding perforations need to be set at the position where the heat dissipation component 30 is led out from the box body. During the glue pouring process, the perforations may cause glue leakage. For example, if the heat dissipation component 30 is led out from the side wall of the electric control box body 24, perforations need to be set at corresponding positions on the side wall. During the glue pouring process, glue leakage may easily occur at the perforation positions. The heat dissipation component 30 is led out from the electric control box body 24, so that the lead-out part of the heat dissipation component 30 is higher than the glue pouring side of the electric control box body 24, and whether or not the perforations for leading out the heat dissipation component 30 are set, the occurrence of glue leakage during the glue pouring process can be avoided or reduced. The structure is reasonable and can facilitate the glue pouring operation on the glue pouring side.

[0104] Reference Figure 3-Figure 12 According to some embodiments of the present invention, the isolation structure is a glue pouring structure, and the wiring harness connected to the electric control component 21 is led out from the glue pouring side of the electric control box body 24. If the wiring harness is led out from other positions on the glue pouring side of the non-electric control box body 24, corresponding perforations need to be set at the position where the wiring harness is led out from the box body. During the glue pouring process, the perforations will cause glue leakage. For example, if the wiring harness is led out from the side wall of the electric control box body 24, perforations need to be set at corresponding positions on the side wall. During the glue pouring process, glue leakage is likely to occur at the perforation positions. The wiring harness is led out from the electric control box body 24, so that the lead-out part of the wiring harness can be higher than the glue pouring side of the electric control box body 24, and regardless of whether perforations for leading out the heat dissipation component 30 are set, glue leakage during the glue pouring process can be avoided or reduced. The structure is reasonable and can facilitate the glue pouring operation on the glue pouring side.

[0105] Reference Figure 3-Figure 7 The heat dissipation component 30 includes at least one heat dissipation element 31, and the heat dissipation element 31 includes a heat dissipation body 32. The heat dissipation body 32 of at least one heat dissipation element 31 is located on the outer peripheral side of the component 23. Since the outer peripheral side area of ​​the component 23 is relatively large, the heat transfer area between the component 23 and the heat dissipation component 30 can be increased, thereby improving the heat dissipation effect of the component 23, thereby improving the heat dissipation effect of the entire electronic control module 20.

[0106] Optionally, the heat sink 31 whose heat sink body 32 is located on the outer peripheral side of the component 23 is a first heat sink 31a, and the heat sink body 32 of at least part of the first heat sink 31a extends in a non-linear manner, such as the heat sink body 32 of part of the first heat sink 31a may extend in a non-linear manner, or the heat sink body 32 of each first heat sink 31a may extend in a non-linear manner. By providing the first heat sink 31a extending along the circumference of the component 23, the heat transfer area between the heat sink body 32 of the first heat sink 31a and the component 23 can be increased, and the heat dissipation efficiency of the first heat sink 31a can be improved to a certain extent, thereby ensuring the heat dissipation effect of the first heat sink 31a on the component 23.

[0107] Optionally, the heat dissipation body 32 of the first heat dissipation member 31a includes a bending portion 33 or a plurality of bending portions 33 arranged at intervals along the extension direction of the first heat dissipation member 31a, and the bending portion 33 includes a plurality of bending sections 34 connected in sequence along the extension direction of the first heat dissipation member 31a, and an angle is formed between two adjacent bending sections 34. By providing the bending section 33, the first heat dissipation member 31a can increase the heat transfer area between the heat dissipation body 32 and the component 23, thereby ensuring the heat dissipation effect of the heat dissipation body 32 on the component 23. The bending sections 34 are connected along the extension direction of the first heat dissipation member 31a to form the bending portion 33, and the structure is relatively simple, which can facilitate the processing and manufacturing of the bending portion 33 to a certain extent.

[0108] For example, the angle between two adjacent bending sections 34 ranges from 90 to 170 degrees. The angle between two adjacent bending sections 34 ranges from 90 to 170 degrees. For example, the angle between the two bending sections 34 can be 90 degrees, 100 degrees, 110 degrees, 120 degrees, 130 degrees, 140 degrees, 150 degrees, 160 degrees, 170 degrees, etc. By setting the angle between the two bending sections to 90 to 170 degrees, a larger angle can be formed between the two bending sections, so that the bending degree of the bending portion 33 is small, which is convenient for processing and manufacturing; in addition, when a heat dissipation channel 36 for the flow of heat dissipation medium is formed in the heat dissipation element 31 When the heat dissipation medium flows through the portion between the two bending sections 34, if the angle between the two bending sections 34 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 34 to 90°~170°, the resistance of the heat dissipation medium flowing through the portion between the two bending sections 34 can be reduced, and the guiding effect of the bending sections 34 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.

[0109] Optionally, the first heat sink 31a further includes a non-bending portion 35 extending in a straight line, the bending section 34 of the bending portion 33 connected to the non-bending portion 35 is a first bending section 341, and the angle between the non-bending portion 35 and the first bending section 341 is in the range of 90 to 170°, for example, the angle between the non-bending portion 35 and the first bending section 341 can be 90°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, 170°, etc. By providing the non-bending portion 35, the processing difficulty and production cost of the first heat sink 31a can be reduced to a certain extent. In addition, when a heat dissipation channel 36 for the flow of heat dissipation medium is formed in the heat sink 31, when the heat dissipation medium flows through the portion between the non-bending portion 35 and the first bending section 341, if the angle between the non-bending portion 35 and the first bending section 341 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 35 and the first bending section 341 to 90° to 170°, the resistance of the heat dissipation medium when flowing through the portion between the non-bending portion 35 and the first bending section 341 can be reduced, and the guiding effect of the first heat dissipation element 31a 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 heat dissipation medium flow. At the same time, by setting the non-bending portion 35, it can further facilitate the flow of the heat dissipation medium in the heat dissipation channel 36. In addition, the non-bending portion 35 can also be used to dissipate heat for components with lower heat generation, or to dissipate heat for densely arranged component areas.

[0110] It should be explained that, if the first bending section 341 is a straight structure, the angle between the non-bending portion 35 and the first bending section 341 refers to the angle between the non-bending portion 35 and the straight line where the first bending section 341 is located; if at least part of the first bending section 341 includes an arc structure, the angle between the non-bending portion 35 and the first bending section 341 refers to the angle between the straight line where the non-bending section 34 is located and the tangent of any point of the arc structure of the first bending section 341.

[0111] Optionally, the heat sink 31 whose heat sink body 32 is located on the outer peripheral side of the component 23 is a first heat sink 31a, and the peripheral side surface of the component 23 is a device side surface 232. The heat sink body 32 of the first heat sink 31a is thermally connected to the device side surface 232. The device side surface 232 of the device is relatively large, so the heat conduction area between the heat sink body 32 and the component 23 can be increased, thereby improving the heat dissipation effect of the first heat sink 31a on the component 23.

[0112] Optionally, the heat dissipation component 30 further includes a second heat dissipation member 31b, the end face of the component 23 in the height direction is the device end face 231, and the heat dissipation body 32 of the second heat dissipation member 31b is thermally connected to the device end face 231. The heat generated by the component 23 thermally connected to the heat dissipation body 32 of the second heat dissipation member 31b during operation can be heat-exchanged with the heat dissipation body 32 of the first heat dissipation member 31a at the device end face 231, thereby controlling the temperature of the component 23 within the normal operating temperature to ensure the stability of the operation of the component 23.

[0113] Among them, one second heat sink 31b can be thermally connected to the device end surface 231 of one or more components 23, one second heat sink 31b can dissipate heat for one component 23, and one second heat sink 31b can dissipate heat for multiple components 23.

[0114] Optionally, the second heat sink 31b can be a straight structure, so that the structure of the second heat sink 31b is simple and easy to process and shape. When the heat sink medium flows in the second heat sink 31b, it is conducive to the smooth flow of the heat sink medium and ensures the heat dissipation effect.

[0115] Optionally, the second heat sink 31b can be a bent setting. For example, when the second heat sink 31b is thermally connected or thermally contacted with multiple components 23, the second heat sink 31b can be bent in the height direction of the components 23, so that the second heat sink 31b can be directly or indirectly thermally connected to the device end surfaces 231 of multiple components with different heights. This setting can reduce the number of second heat sinks 31b and achieve a single second heat sink 31b to dissipate heat for multiple components 23 at the same time.

[0116] Reference Figure 2 as well as Figure 8-Figure 12 The heat dissipation component 30 includes at least one heat dissipation element 31, and the heat dissipation element 31 includes a heat dissipation body 32. The heat dissipation body 32 is thermally connected to the electronic control component 21. The heat dissipation body 32 of at least one heat dissipation element 31 is bent to be thermally connected to at least two components 23 of different heights. The end surface of the component 23 in the height direction is the component end surface 231, and the heat dissipation body 32 is thermally connected to the component end surface 231. The heat dissipation body 32 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.

[0117] Optionally, the heat dissipation component 30 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 at least one straight section 40 and a connecting section 41 connected between adjacent straight sections 40, the straight section 40 and the connecting section 41 have an angle, the straight section 40 is thermally connected to the device end face 231, and the heights of the components 23 corresponding to the plurality of straight sections 40 of the same heat dissipation body 32 are different. The fourth heat dissipation member 31d is a straight structure and can be thermally connected to the device end face 231. The straight section 40 of the heat dissipation body 32 is thermally connected to the device end face 231, so that the straight section 40 of the heat dissipation body 32 can be matched with the device end face 231 of the component 23, so that the straight section 40 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 large, and the heat dissipation efficiency of the component 23 can be improved.

[0118] Optionally, the connecting section 41 of the heat dissipation body 32 is used to connect two adjacent straight sections 40, and the two adjacent straight sections 40 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 40 of the same heat dissipation body 32 correspond to components 23 at different heights, so the connecting section 41 connected between two adjacent straight sections 40 has an angle with the two adjacent straight sections 40. 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.

[0119] For example, the angle between the straight section 40 and the connecting section 41 is 90° to 170°. For example, the angle between the straight section 321 and the connecting section 322 can 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 40 and the connecting section 41, 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 36 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 40 and the connecting section 41, if the angle between the straight section 40 and the connecting section 41 is too small, it will cause greater resistance to the flow of the heat dissipation medium. By setting the angle between the straight section 40 and the connecting section 41 to 90°~170°, the resistance of the heat dissipation medium when flowing through the part between the straight section 40 and the connecting section 41 can be reduced, and the guiding effect of the connecting section 41 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.

[0120] Optionally, the electric control assembly 21 includes a component group 46 corresponding to each heat sink 31, and the component group 46 includes a first component group 46a and a second component group 46b. There is a large height difference between at least some of the adjacent components 23 in the first component group 46a, and the bent third heat sink 31c is thermally connected to the first component group 46a; the components 23 in the second component group 46b are of the same height or have a small height difference, and the fourth heat sink 31d of the straight structure is thermally connected to the second component group 46b. By setting the component group 46, the spatial layout inside the electric control module assembly 10 can be regionalized and rationalized. In addition, by setting the component group 46, components 23 of different heights can be rationally classified to facilitate the arrangement of the heat sink 31.

[0121] Optionally, the heat dissipation component 30 is used to dissipate heat for the electric control module 20 and includes at least one heat dissipation element 31. The heat dissipation element 31 includes a heat dissipation body 32. The heat dissipation body 32 is thermally connected to the electric control component 21. A heat conductive layer is provided between the heat dissipation body 32 and the component 23 to ensure the connection and heat conduction effect between the heat dissipation body 32 and the component 23. The heat conductive layer can be one or more of a heat conductive adhesive, a heat conductive silicone grease, a heat conductive pad or a heat conductive metal. For example, the heat conductive layer can be a heat conductive adhesive, a heat conductive silicone grease, a heat conductive pad or a heat conductive metal; the heat conductive layer can also include at least two of the heat conductive adhesive, the heat conductive silicone grease, the heat conductive pad and the heat conductive metal. When the heat conductive layer includes at least two of the heat conductive adhesive, the heat conductive silicone grease, the heat conductive pad and the heat conductive metal, the two heat conductive structures can be stacked along the thickness direction of the heat conductive layer, and the two heat conductive structures can also be mixed with each other to form a heat conductive layer.

[0122] Reference Figure 3 According to some embodiments of the present invention, the heat dissipation component 30 includes a heat dissipation element 31, and the heat dissipation element 31 includes a heat dissipation body 32 located in the electric control box body 24, and a heat dissipation channel 36 for the heat dissipation medium to flow is formed in the heat dissipation element 31. By providing the heat dissipation element 31, a heat dissipation channel 36 is formed in the heat dissipation element 31, and the heat dissipation channel 36 has a flow-guiding effect on the heat dissipation medium located inside the heat dissipation channel 36. The heat dissipation body 32 of the heat dissipation element 31 located in the electric control box body 24 can exchange heat with the components 23 in the electric control box through the flow of the heat dissipation medium therein, thereby realizing the heat dissipation function of the heat dissipation element 30.

[0123] Reference Figure 3-Figure 12 According to some embodiments of the present invention, the heat dissipation component 30 includes a medium inlet pipe 37 and a medium outlet pipe 38, and the heat dissipation channel 36 connects the medium inlet pipe 37 and the medium outlet pipe 38. The heat dissipation medium enters the heat dissipation channel 36 from the medium inlet pipe, absorbs the heat generated by the components 23 during operation in the heat dissipation channel 36, and then flows out from the medium outlet pipe 38. Through this arrangement, the structure is simple and the heat dissipation efficiency is high.

[0124] Reference Figure 5 and Fig.10 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 37 and the same medium outlet pipe 38 by being arranged in parallel, thereby reducing the number of medium inlet pipes 37 and medium outlet pipes 38 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.

[0125] For example, refer to Figure 5 as well as Fig.10 The heat dissipation component 30 includes two heat dissipation elements 31, which are arranged in parallel and share a medium inlet pipe 37 and a medium outlet pipe 38, which can reduce the number of medium inlet pipes 37 and medium outlet pipes 38, reduce production costs, and at the same time, the structure is simple and can improve space utilization. The heat dissipation medium enters the heat dissipation channels 36 of the two heat dissipation elements 31 from the medium inlet pipe 37 respectively. During the flow process, the heat of the two heat dissipation elements 31 respectively absorbs the heat of the components 23, and then flows out from the medium outlet pipe 38 after being collected at the medium outlet pipe 38, so that the heat dissipation of the components 23 is more uniform, which can further improve the heat dissipation effect of the heat dissipation component 30.

[0126] Reference Figure 5 and Fig.10 According to some embodiments of the present invention, the medium inlet pipe 37 and the medium outlet pipe 38 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.

[0127] Through this arrangement, the structure of the medium inlet pipe 37, the medium outlet pipe 38 and the heat dissipation channel 36 is simple, and the internal space of the battery module assembly can be fully utilized, and the layout is relatively reasonable. In addition, the heat dissipation element 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 dissipation elements 31 can be reduced, and the length of the medium inlet pipe 37 and the medium outlet pipe 38 can be shortened.

[0128] For example, refer to Figure 5 as well as Fig.10 The heat sink 31 extends along the length direction of the electric control board 22 , and the two heat sinks 31 are arranged along the width direction of the electric control board 22 .

[0129] Reference Figure 4 and Fig. 9According to some embodiments of the present invention, the inner wall of the electric control box body 24 is provided with a third limiting structure 27, and the medium inlet pipe 37 and the medium outlet pipe 38 cooperate with the third limiting structure 27 to limit the medium inlet pipe 37 and the medium outlet pipe 38. The inner wall of the electric control box body 24 is provided with the third limiting structure 27, which can realize the limiting effect of the electric control box body 24 on the medium inlet pipe 37 and the medium outlet pipe 38, and can ensure the stability of the position of the medium inlet pipe 37 and the medium outlet pipe 38, thereby ensuring the stability of the heat dissipation effect of the heat sink 31 on the components 23.

[0130] For example, refer to Figure 6 Two limiting protrusions are formed on the inner wall edges of both sides in the length direction of the first box body 241, and the four limiting protrusions are all third limiting structures 27. Limiting notches matching the two limiting protrusions can be respectively set at the corresponding positions of the medium inlet pipe 37 and the medium outlet pipe 38. The third limiting structure 27 can limit the medium inlet pipe 37 and the medium outlet pipe 38 through the cooperation of the limiting protrusions and the limiting notches. In addition, through this arrangement, the assembly of the medium inlet pipe 37 and the medium outlet pipe 38 with the electric control box body 24 can be facilitated.

[0131] For example, refer to Fig.11 Two detachable clamping holes are formed on both sides of the length direction of the first box body 241, and both clamping holes are third limiting structures 27. The medium inlet pipe 37 and the medium outlet pipe 38 can be matched with the clamping holes respectively, and after the matching is completed, they are clamped at the corresponding positions of the electric control box body 24, so as to realize the limiting effect of the third limiting structure 27 on the medium outlet pipe 38 and the medium inlet pipe 37. In addition, through this setting, it is convenient to assemble the medium inlet pipe 37 and the medium outlet pipe 38 with the electric control box body 24.

[0132] Reference Figure 4 and Fig. 9 According to some embodiments of the present invention, a portion of the medium inlet pipe 37 and a portion of the medium outlet pipe 38 are located between the outer edge of the electric control board 22 and the inner wall of the electric control box body 24. Through this arrangement, the arrangement of the heat dissipation component 30 inside the electric control box body 24 can be made more reasonable, and the internal space of the electric control box body 24 can be fully utilized to improve the space utilization rate. In addition, when the isolation structure is a glue pouring structure, this arrangement can prevent the potting glue from entering the medium inlet pipe 37 and the medium outlet pipe 38 during the glue pouring operation, so that the glue pouring operation inside the electric control box body 24 can be conveniently performed, and the heat dissipation effect of the heat dissipation component 30 can be ensured at the same time.

[0133] Reference Figure 1-Figure 2According to some embodiments of the present invention, the heat sink 31 is a phase-change heat sink and includes a heat absorbing section 42 and a heat dissipating section 43. The heat dissipating medium in the heat sink 31 is suitable for circulating between the heat absorbing section 42 and the heat dissipating section 43. The heat absorbing section 42 includes a heat dissipating body 32. The heat absorbing section 42 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 43 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 43 again to absorb heat after the heat dissipation is completed, thereby achieving the circulation of the heat dissipating medium between the heat absorbing section 42 and the heat dissipating section 43.

[0134] During the operation of the heat sink 31, the heat dissipation medium located in the heat absorption section 42 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 43 through the heat dissipation channel 36. The gaseous heat dissipation medium condenses in the heat dissipation section 43, and is converted from a high-temperature gas to a low-temperature liquid again. Finally, it flows to the heat absorption section 42 through the heat dissipation channel 36, 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 42 and the heat dissipation section 43, and completes the functions of heat absorption and heat dissipation through the phase change of the heat dissipation medium in the heat dissipation channel 36, thereby realizing the function of the heat sink 31 to circulate and dissipate heat for the component 23.

[0135] Reference Figure 1-Figure 12 According to the glue pouring method of the electric control module assembly 10 of the second embodiment of the present invention, the electric control module assembly 10 is the electric control module assembly 10 of the first embodiment of the present invention, and the glue pouring method includes:

[0136] Assemble the electric control assembly 21 and the heat dissipation component 30 to the electric control box body 24 to form a pre-assembled body;

[0138] For example, when glue is poured using the glue pouring port 44 in the gap between the outer edge of the electric control board 22 and the inner wall of the first box body 241, the second side 222 of the electric control board 22 is the glue pouring side, and the pre-assembly is adjusted so that the second side 222 of the electric control board 22 faces upward; when glue is poured using the first glue pouring hole 45 on the electric control board 22, the second side 222 of the electric control board 22 is the glue pouring side, and the pre-assembly is adjusted so that the second side 222 of the electric control board 22 faces upward; when glue is poured using the second glue pouring hole located in the electric control box body 24, the first side 221 of the electric control board 22 is the glue pouring side, and the pre-assembly is adjusted so that the first side 221 of the electric control board 22 faces upward.

[0139] The insulating structure is formed by pouring glue into the electric control box body 24 from the glue pouring side of the electric control box body 24 .

[0140] According to the glue filling method of the embodiment of the present invention, an isolation structure can be formed in the electric control box body 24, so that the components 23 can be isolated from the air, thereby avoiding condensation on the components 23 of the electric control module 20, thereby improving the reliability, stability and safety of the electric control module 20; in addition, when there are flammable and explosive gases in the environment where the electric control module 20 is located, by providing an isolation structure and the isolation structure covering the outer surface of the components, the safety hazard of ignition and explosion caused by the contact between the flammable and explosive gases and the components 23 can be eliminated, and at the same time, it can also enhance the vibration resistance of the electric control module 20, prevent the components 23 from detaching, buffer and protect the components 23, and prevent dust.

[0141] Reference Figure 1-Figure 12 According to some embodiments of the present invention, the electric control assembly 21 and the heat dissipation component 30 are assembled in the electric control box body 24 to form a pre-assembled body, including: assembling part of the heat dissipation component 30 in the electric control assembly 21, assembling the electric control assembly 21 equipped with the heat dissipation component 30 in the first box body 241 of the electric control box body 24, and making the first side 221 of the electric control board 22 face the first box body 241, and the first side 221 of the electric control board 22 is provided with a component 23;

[0143] The insulating structure is formed by pouring glue into the electric control box body 24 from the glue pouring side of the electric control box body 24, including: pouring glue from the second side 222 of the electric control board 22 toward the first box body 241 to form an insulating structure, and assembling the second box body 242 of the electric control box body 24 to the first box body 241. During the pouring process, the potting glue is poured from the second side 222 of the electric control board 22 to the filling space, and the potting glue flows from the second side 222 of the electric control board 22 to the lowest point of the filling space under the action of gravity, until the entire filling space is filled, so that the outer surfaces of the multiple components 23 located inside the filling space can be covered, so that the components 23 are isolated from the air, and condensation is prevented from being generated by cooling of the components 23. After the pouring is completed, the second box body 242 of the electric control box body 24 is assembled to the first box body 241, and the operation is simple.

[0144] Reference Figure 1-Figure 12The outdoor unit 100 according to the third 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, the outdoor fan 12, the compressor assembly 13 and the electric control module assembly 10 are all arranged in the outdoor housing 11, and the electric control module assembly 10 is the electric control module assembly 10 according to the first embodiment of the present invention. During the operation of the outdoor unit 100, the temperature of the electric control module 20 rises. By providing a heat dissipation component 30 in the electric control module assembly 10, the heat generated by the electric control module 20 during the operation process can be dissipated through the heat dissipation component 30, thereby controlling the temperature of the electric control assembly 21 within the normal operating temperature to ensure the stability of the operation of the electric control module 20.

[0145] According to the outdoor unit 100 of the embodiment of the present invention, by providing the above-mentioned electric control module assembly 10, the heat dissipation effect of the electric control module 20 can be improved, and by providing an isolation structure, the components 23 can be isolated from the air, thereby avoiding condensation on the components 23 of the electric control module 20, thereby improving the reliability, stability and safety of the electric control module 20; in addition, when there are flammable and explosive gases in the environment where the electric control module 20 is located, by providing an isolation structure and the isolation structure covering the outer surface of the components 23, the safety hazard of ignition and explosion caused by the contact between the flammable and explosive gases and the components 23 can be eliminated, and at the same time, it can also enhance the vibration resistance of the electric control module 20, prevent the components 23 from detaching, buffer and protect the components 23, and prevent dust.

[0146] Reference Figure 1-Figure 2 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 electronic control module 20, and the cooling part 15 is thermally connected to the heat dissipation component 30 or at least a part of the cooling part 15 constitutes the heat dissipation component 30.

[0147] The refrigerant circulation system of the outdoor unit 100 includes a cooling unit 15 for dissipating heat from the electric control module 20 . Through this arrangement, the refrigerant in the refrigerant circulation system can be used to take away the heat generated by the electric control module 20 .

[0148] 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.

[0149] For example, refer to Figure 1-Figure 2The heat dissipation component 30 includes two heat dissipation elements 31, which are phase change heat dissipation elements and include a heat absorption section 42 and a heat dissipation section 43. The heat dissipation medium in the heat dissipation element 31 is suitable for circulating between the heat absorption section 42 and the heat dissipation section 43. The heat absorption section 42 includes a heat dissipation body 32. The heat dissipation section 43 is thermally connected to the cooling part 15 through a heat conductive substrate 53. The cooling part 15 can exchange heat with the heat dissipation medium of the heat dissipation section 43 to achieve the heat dissipation function of the heat dissipation section 43.

[0150] 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 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.

[0151] For example, refer to Figure 3 as well as Figure 8 At least part of the cooling unit 15 constitutes a heat dissipation component 30, and the heat generated by the electronic control module 20 can be directly transferred to the cooling unit 15, and the heat is taken away by the refrigerant flowing through the cooling unit 15, thereby achieving indirect heat dissipation and cooling of the electronic control module 20 by the refrigerant.

[0152] Reference Figure 1-Figure 2 According to some embodiments of the present invention, it also includes a water heat exchange component, which includes a water heat exchanger 14, and the water heat exchanger 14 has a water flow channel and a refrigerant channel for mutual heat exchange, and the water cooling part 15 is connected between the refrigerant channel and the inlet of the outdoor heat exchanger. 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 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.

[0153] Optionally, the water heat exchanger 14 may be a plate heat exchanger.

[0154] 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.

[0155] 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. 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.

[0156] 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. 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.

[0157] Optionally, the water path heat exchanger 14 also includes a water path inlet 50 and a water path outlet 51. The water entering the water flow channel through the water path inlet 50 exchanges heat with the refrigerant in the refrigerant channel. After the water in the water flow channel flows out of the water path heat exchanger 14 after heat exchange, the temperature of the water can be changed and flows out from the water path outlet 51. The water with the temperature 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.

[0158] Optionally, the refrigerant circulation system may be provided with a throttling component 52 to control parameters such as the flow rate of the refrigerant in the refrigerant circulation system.

[0168] The electric control box body 24 includes a first box body 241 and a second box body 242 which are independently formed. The electric control assembly 21 is arranged in the first box body 241. The first side 221 of the electric control board 22 faces the first box body 241 and defines a filling space between the electric control board 22 and the first box body 241. The inner wall of the first box body 241 is formed with a second limiting structure 26 for limiting the position of the electric control board 22 and a first fixing column 28 for fixing the electric control board 22.

After the positioning is completed, the electric control board 22 and the first box body 241 can be connected and fixed by the first fixing column 28.

[0169] There is a gap between the outer edge of the electric control board 22 and the inner wall of the first box body 241, and at least part of the gap can constitute a glue filling port 44, which is connected to the filling space; a first glue filling hole 45 connected to the filling space is also formed on the electric control board 22, and the equivalent diameter of the first glue filling hole 45 is greater than 10 mm and is located in the middle of the electric control board 22.

[0170] A second fixing column 29 connected to the second box body 242 is disposed in the first box body 241 . The surface of the second side 222 of the electric control board 22 is the back of the board. The second fixing column 29 is located on the outer peripheral side of the electric control board 22 and protrudes from the back of the board.

[0171] The heat dissipation component 30 is led out from the glue-filled side of the electric control box body 24, and the wiring harness connected to the electric control component 21 is led out from the glue-filled side of the electric control box body 24. The heat dissipation component 30 includes a heat dissipation element 31, and the heat dissipation element 31 includes a heat dissipation body 32 located in the electric control box body 24, and a heat dissipation channel 36 for the heat dissipation medium to flow is formed in the heat dissipation element 31.

[0172] The heat dissipation component 30 includes a medium inlet pipe 37 and a medium outlet pipe 38, and the heat dissipation channel 36 connects the medium inlet pipe 37 and the medium outlet pipe 38. Two heat dissipation members 31 are arranged in parallel, and the medium inlet pipe 37 and the medium outlet pipe 38 are located on both sides of the length direction of the electric control board 22. The heat dissipation members 31 extend along the length direction of the electric control board 22, and the two heat dissipation members 31 are arranged along the width direction of the electric control board 22.

[0173] The inner wall of the electric control box body 24 is also provided with a third limiting structure 27, and the medium inlet pipe 37 and the medium outlet pipe 38 cooperate with the third limiting structure 27 to limit the medium inlet pipe 37 and the medium outlet pipe 38.

[0174] The heat dissipation component 30 can dissipate heat for the electric control module 20, and by providing an isolation structure and making the isolation structure cover the outer surface of the component 23, the component 23 can be isolated from the air, thereby avoiding condensation on the component 23 of the electric control module 20, and improving the reliability, stability and safety of the electric control module 20.

[0175] Refer to the following Figure 3-Figure 12 , describing the glue filling method of the electric control module assembly 10 of this embodiment: comprising:

[0176] The electric control assembly 21 and the heat dissipation component 30 are assembled in the electric control box body 24 to form a pre-assembled body. In the process of forming the pre-assembled body, firstly, according to the corresponding relationship between the components 23 on the electric control board 22 and the heat dissipation component 31, the electric control board 22 and the heat dissipation component 30 are assembled, so that the heat dissipation component 30 is fixed on the electric control board 22, for example, the electric control board 22 and the heat dissipation component 30 can be positioned by bonding; after the fixing is completed, the electric control board 22 is turned upside down into the first box body 241, so that the first side 221 of the electric control board 22 faces the first box body 241, and the heat dissipation component 30, the electric control board 22 and the first box body 241 are positioned by the first limiting structure 25, the second limiting structure 26 and the third limiting structure 27; finally, the electric control board 22 and the first box body 241 are connected and fixed by the first fixing column 28 to form a pre-assembled body. For example, the connection and fixation of the electric control board 22 and the first box body 241 can be completed by the cooperation of the fastener and the first fixing column 28. At this time, a filling space is defined between the first side 221 of the electric control board 22 and the electric control box body 24 , and the components 23 and the heat dissipation component 30 are both located in the filling space.

[0177] The pre-assembled body is adjusted so that the glue injection side of the electric control box body 24 faces upward. In the process of injecting glue from the glue injection side of the electric control board 22 into the filling space, glue injection can be selected to be injected into the filling space through the glue injection port 44 formed by the gap around the electric control board 22 and the inner wall of the first box body 241; glue injection can be selected to be injected into the filling space through the first glue injection hole 45 on the electric control board 22; or glue injection can be selected to be injected into the filling space through the glue injection port 44 and the first glue injection hole 45 at the same time.

[0178] The insulating structure is formed by pouring glue into the electric control box body 24 from the pouring side of the electric control box body 24. During the pouring process, the pouring glue is poured into the filling space from the pouring side of the electric control board 22. Under the action of gravity, the pouring glue flows from the second side 222 of the electric control board 22 to the lowest point of the filling space until the entire filling space is filled, thereby covering the outer surfaces of the multiple components 23 located inside the filling space, so that the components 23 are isolated from the air.

[0179] After the potting operation is completed and the potting glue is solidified, the first box body 241 and the second box body 242 are connected by the second fixing column 29 to form a final assembly. For example, the first box body 241 and the second box body 242 can be connected and fixed by the cooperation of the fastener and the first fixing column 28.

[0180] The glue filling method of this embodiment is simple. At the same time, the glue filling structure has a good insulation effect, which can isolate the components 23 from the air, thereby avoiding condensation on the components 23 of the electronic control module 20, thereby improving the reliability, stability and safety of the electronic control module 20; in addition, when there are flammable and explosive gases in the environment where the electronic control module 20 is located, by providing an isolation structure and the isolation structure covering the outer surface of the components 23, the safety hazard of ignition and explosion caused by the contact between the flammable and explosive gases and the components 23 can be eliminated. At the same time, it can also enhance the vibration resistance of the electronic control module 20, prevent the components 23 from detaching, buffer and protect the components 23, and prevent dust.
