[0049] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation to the present invention.

[0050] Next, refer to Figure 2 to describe an inductor assembly according to an embodiment of the present invention, which can be used in an electronic control device.

[0051] As Figure 2As shown, the inductance component according to an embodiment of the present invention includes: an inductor 122 and a heat conducting member 3 for conducting the heat of the inductor 122. The heat conducting member 3 can exchange heat with the inductor 122. Specifically, when the inductor 122 is operating, a large amount of heat is generated, which greatly increases the operating temperature of the inductor 122. An excessively high operating temperature will affect the normal operation of the inductor 122. The heat conducting member 3 can exchange heat with the inductor 122, and the heat conducting member 3 can also conduct the heat generated by the inductor 122, thereby preventing heat from accumulating in the inductor 122 and playing a role in quickly dissipating the heat of the inductor 122. Among them, the part of the heat conducting member 3 in contact with the inductor 122 can be an insulating part 31. It can be understood that the insulating part 31 has the functions of heat conduction and preventing electricity conduction, thereby ensuring the normal operation of the inductor 122.

[0052] In a specific example of the present invention, the inductance component can be used in an electric control device. A heat dissipation part is provided on the housing of the electric control device, and one end of the heat conducting member 3 is connected to the heat dissipation part. When the electric control device is operating, the heat generated by the inductor 122 can be transferred to the heat dissipation part through the heat conducting member 3, and the heat dissipation part can transfer the heat from the inductor 122 to the outside of the electric control device. Thus, it can play a role in quickly dissipating the heat of the inductor 122 and the electric control device, enabling the electric control device to operate at an appropriate working temperature, and thereby improving the operation stability of the electric control device.

[0053] According to the inductance component of the embodiment of the present invention, by providing the heat conducting member 3, the heat conducting member 3 can conduct the heat generated by the inductor 122, thereby preventing heat from accumulating in the inductor 122, playing a role in quickly dissipating the heat of the inductor 122, and further ensuring the normal operation of the inductor 122.

[0054] As Figure 2 shown, according to some embodiments of the present invention, the inductance component may further include a support base 124. The heat conducting member 3 can be placed on the support base 124, thereby facilitating the assembly of the inductor 122 and the heat conducting member 3. Optionally, the inductance component can be assembled with a PCB board. The support base 124 can be fixed to the PCB board by means of screw connection or welding. A receiving space for the heat conducting member 3 is provided on the support base 124, the heat conducting member 3 is placed in the receiving space, and the inductor 122 is placed on the heat conducting member 3.

[0055] For example, the inductor 122 can be formed in a disc shape, the receiving space can be formed as a downwardly concave assembly groove, and the heat conducting member 3 can be formed in an arc shape and closely fit with the inner peripheral wall of the assembly groove. When the inductor 122 is assembled with the support base 124, a part of the inductor 122 can be received in the assembly groove and closely fit with the upper surface of the heat conducting member 3. Thus, through the above settings, the cooperation structure of the inductor 122 with the support base 124 and the heat conducting member 3 can be made more firm, and the heat conduction efficiency of the heat conducting member 3 can also be improved.

[0056] As Figure 2 shown, according to some embodiments of the present invention, the heat conducting member 3 may include a metal part 32 provided on the insulating part 31, whereby the heat conduction efficiency of the heat conducting member 3 can be improved. It can be understood that the heat conduction efficiency of the metal material is relatively high, and the heat generated by the inductor 122 can be transferred to the metal part 32 through the insulating part 31, and the metal part 32 can quickly conduct the heat out, thereby improving the heat dissipation efficiency of the inductor assembly.

[0057] Optionally, the insulating part 31 and the metal part 32 may be separate parts, or the insulating part 31 and the metal part 32 may be integrally formed. For example, as Figure 2 shown, the heat conducting member 3 includes a separately designed insulating part 31 and a metal part 32, the metal part 32 is placed on the support seat 124, and the insulating part 31 is located between the inductor 122 and the metal part 32. Thus, through the above arrangement, the insulating part 31 can prevent the occurrence of electric leakage between the inductor 122 and the metal part 32, and the insulating part 31 can also transfer the heat generated by the inductor 122 to the metal part.

[0058] Next, reference is made to Figures 1 - 10 describe the electronic control assembly 100 according to an embodiment of the present invention, which can be used in an air conditioner. Among them, a liquid storage tank 200 may be provided in the air conditioner.

[0059] As Figures 1 - 4 、 Figure 10 shown, the electronic control assembly 100 according to an embodiment of the present invention includes: an electronic control box assembly 1, a radiator 2, and a heat conducting member 3.

[0060] As Figure 10 shown, the electronic control box assembly 1 may include a box body 11 and an electronic control device 12 provided in the box body 11. The electronic control device 12 may include a circuit board 121, an inductor 122 provided on the circuit board 121, and a control component 123 provided on the circuit board 121. The radiator 2 can be used to dissipate heat from the control component 123, and the heat conducting member 3 may have an insulating part 31 in contact with the inductor 122, and the heat conducting member 3 can be in contact with the heat dissipation part of the box body 11 and / or the radiator 2.

[0061] Specifically, the circuit board 121 can be fixed on the inner peripheral wall of the box body 11. An inductor 122 and control components 123 can be provided on the circuit board 121. When the electric control device 12 operates, both the inductor 122 and the control components 123 can generate a large amount of heat, thereby increasing the operating temperature of the electric control device 12. To ensure the normal operation of the electric control device 12, it is necessary to cool the electric control device 12. The radiator 2 can be used to dissipate heat from the control components 123, thereby reducing the operating temperature of the control components 123 and ensuring the normal operation of the control components 123.

[0062] The heat conducting member 3 can play a role in transferring heat. An insulating portion 31 can be provided on the heat conducting member 3. The insulating portion 31 has the functions of heat conduction and preventing electricity conduction, thereby ensuring the normal operation of the inductor 122. Among them, the heat conducting member 3 can be in contact with the heat dissipation portion on the box body 11, the heat conducting member 3 can also be in contact with the radiator 2, and the heat conducting member 3 can also be in contact with both the heat dissipation portion on the box body 11 and the radiator 2 at the same time. When the heat conducting member 3 is in contact with the heat dissipation portion on the box body 11, the heat conducting member 3 can transfer the heat generated by the inductor 122 to the heat dissipation portion on the box body 11, and natural convection can be used to cool the heat dissipation portion, thereby playing a role in cooling the inductor 122. When the heat conducting member 3 is in contact with the radiator 2, the heat conducting member 3 can transfer the heat generated by the inductor 122 to the radiator 2, and then the radiator 2 can be used to dissipate heat from the inductor 122.

[0063] Thus, through the above settings, the heat conducting member 3 can transfer the heat generated by the inductor 122 in the box body 11 to the heat dissipation portion on the box body 11 and / or the radiator 2, and the inductor 122 can be effectively cooled without affecting the sealing performance of the box body 11. It can not only prevent the condensed water in the air conditioner from flowing onto the electric control device 12, but also enable the inductor 122 to operate at an appropriate working temperature, improving the operation stability of the air conditioner.

[0064] Optionally, the heat dissipation portion on the box body 11 can be a part of the box body 11, or the heat dissipation portion can be a heat dissipation device. The heat dissipation portion can be provided on the outer peripheral wall of the box body 11 and can cool the heat conducting member 3, thereby reducing the temperature of the inductor 122.

[0065] Next, refer to Figure 1 and Figure 10 to describe the electric control device 12 of the present invention in detail with a specific embodiment.

[0066] The electronic control device 12 includes a circuit board 121, and the circuit board 121 is fixed on the inner peripheral wall of the box body 11. Control components 123, an inductor 122, and a capacitor 125 are provided on the circuit board 121. The control component 123 is an IPM module. One end of the IPM module is connected to the circuit board 121, and the other end of the IPM module is in contact with the radiator 2. The inductor 122 and the capacitor 125 are arranged on the same side of the IPM module (such as Figure 4 the left side shown). The inductor 122 and the capacitor 125 are spaced apart in the length direction of the circuit board 121 (such as Figure 1 and Figure 4 the front-back direction shown). The inductor 122 is formed in a disc shape. The inductor 122 is spaced apart from the IPM module. A heat conducting member 3 is provided below the inductor 122. The insulating portion 31 of the heat conducting member 3 is in contact with the inductor 122. One end of the heat conducting member 3 is connected to the heat dissipation portion on the box body 11.

[0067] When the electronic control device 12 operates, the heat generated by the IPM module can be transferred to the radiator 2, and the radiator 2 can transfer the heat from the IPM module to the outer surface of the liquid storage tank 200. The temperature of the outer surface of the liquid storage tank 200 can be used to cool the IPM module. The heat generated by the inductor 122 can be transferred to the heat dissipation portion on the box body 11 through the heat conducting member 3. When the heat propagates on the heat dissipation portion, natural convection can be used to exchange heat with the air flow, so as to achieve the purpose of cooling the inductor 122.

[0068] For the electronic control assembly 100 according to the embodiment of the present invention, by providing the heat conducting member 3, the heat conducting member 3 can transfer the heat generated by the inductor 122 to the box body 11 and / or the radiator 2. Thus, on the basis of not affecting the sealing performance of the electronic control box assembly 1, the inductor 122 can be quickly cooled, so as to ensure the normal operation of the electronic control assembly 100. The electronic control assembly 100 has good structural sealing performance and good heat dissipation effect, and has strong practical performance.

[0069] As Figure 4 shown, according to some embodiments of the present invention, at least a part of the radiator 2 can be in contact with the control component 123 to perform heat exchange with the control component 123, so as to improve the heat dissipation efficiency of the control component 123. It can be understood that at least a part of the radiator 2 can be directly in contact with the control component 123, and at least a part of the radiator 2 can also be indirectly in contact with the control component 123. For example, heat conducting silicone can be provided between the control component 123 and the radiator 2, and the heat conducting silicone can transfer the heat generated by the control component 123 to the radiator 2. For another example, the radiator 2 can be attached to the outer surface of the control component 123, and the heat generated by the control component 123 can be directly transferred to the radiator 2.

[0070] AsFigures 9 - 10 As shown, the electronic control component 100 can be arranged on the liquid storage tank 200. At least a part of the radiator 2 can extend out of the box body 11 to contact the outer peripheral wall of the liquid storage tank 200 for heat exchange, thereby improving the heat dissipation efficiency of the radiator 2. It can be understood that since the temperature on the outer peripheral wall of the liquid storage tank 200 is relatively low, the contact between the radiator 2 and the outer peripheral wall of the liquid storage tank 200 can transfer heat to the liquid storage tank 200, and the temperature of the outer surface of the liquid storage tank 200 can be used to cool the radiator 2. It should be noted that the radiator 2 can be in direct contact with the outer peripheral wall of the liquid storage tank 200, or the radiator 2 can be in indirect contact with the outer peripheral wall of the liquid storage tank 200, and it can be selected according to actual installation requirements.

[0071] Optionally, as Figure 10 shown, the radiator 2 can be attached to the outer peripheral wall of the liquid storage tank 200, thereby making the cooperation structure between the radiator 2 and the liquid storage tank 200 simpler. This can not only improve the assembly efficiency but also improve the heat dissipation efficiency of the radiator 2. Further, the radiator 2 can be fixed on the liquid storage tank 200 by welding.

[0072] In some embodiments of the present invention, the box body 11 can be a heat-conducting material part, thereby improving the heat dissipation efficiency of the heat-conducting part 3. Specifically, the heat-conducting part 3 can transfer the heat generated by the inductor to the box body 11, and while the heat propagates on the box body 11, it can exchange heat with the air flow, thereby improving the heat dissipation efficiency. Optionally, the box body 11 can be a metal material part. For example, the box body 11 can be made of iron or aluminum material.

[0073] As Figure 2 shown, according to some embodiments of the present invention, the heat-conducting part 3 can include a metal part 32 arranged on an insulating part 31. The metal part 32 can contact the box body 11 and / or the radiator 2, thereby improving the heat conduction efficiency of the heat-conducting part 3. It can be understood that the heat conduction performance of the metal material is good, and the metal part 32 can quickly transfer the heat on the insulating part 31 to the box body 11 and / or the radiator 2, thereby improving the heat dissipation efficiency of the inductor 122.

[0074] Optionally, the metal part 32 can be a copper material part or an aluminum material part. The heat conduction efficiency of copper is 397W / m.K, thereby greatly improving the heat conduction efficiency of the heat-conducting part 3. Of course, the metal part 32 can also be other metal material parts. For example, the metal part 32 can also be a cast iron material part or an aluminum material part, and it can be selected according to actual usage requirements. The present invention does not make specific limitations on this.

[0075] Optionally, the insulating part 31 and the metal part 32 can be integrally formed parts, whereby the structure of the heat conducting part 3 can be made simpler, and the assembly of the heat conducting part 3 can be facilitated. For example, the insulating part 31 and the metal part 32 can be integrally injection molded parts. The metal part 32 can be placed in a mold, and there is an injection molding area on the metal part 32. The liquid insulating material can be injected into the mold, and the liquid insulating material can fill the injection molding area. After the mold is opened, the integrally formed heat conducting part 3 can be obtained.

[0076] Of course, it can be understood that the insulating part 31 and the metal part 32 can also be separate parts. The insulating part 31 can be placed on the metal part 32, and the insulating part 31 can be in direct contact with the inductor 122, whereby the contact area between the insulating part 31 and the metal part 32 can be increased. For example, as Figure 2 、 Figures 7 - 8 shown, the heat conducting part 3 includes a separately designed metal part 32 and an insulating part 31. The insulating part 31 is placed on the metal part 32, and the inductor 122 is provided on the insulating part 31. Among them, the inductor 122 is formed in a disc shape. There is a first placement groove 321a recessed downward on the metal part 32, and a second placement groove 311 recessed downward on the insulating part 31. A part of the insulating part 31 can be arranged in the first placement groove 321a, and a part of the inductor 122 is received in the second placement groove 311. Thus, through the above settings, the cooperation structure between the inductor 122 and the heat conducting part 3 can be made more firm and compact.

[0077] As Figures 2 - 3 shown, in some embodiments of the present invention, the metal part 32 can include a support part 321 and a connection part 322. Both the insulating part 31 and the inductor 122 can be provided on the support part 321, and the connection part 322 can be in contact with the box body 11 or the radiator 2, whereby the installation and fixation of the heat conducting part 3 can be facilitated. Specifically, the support part 321 is used to support the insulating part 31 and the inductor 122, and the connection part 322 can be connected to the box body 11 to fix the heat conducting part 3.

[0078] As Figure 5As shown, in some embodiments of the present invention, the box body 11 may be provided with an inwardly (in the direction close to the electronic control device 12) recessed mounting portion 111a. The connecting member 4 may pass through the mounting portion 111a and the connecting portion 322 to fix the heat conducting member 3 on the box body 11, thereby making the fixing method of the heat conducting member 3 simpler. For example, a first mounting hole 111a1 may be provided on the mounting portion 111a, a second mounting hole 322a may be provided on the connecting portion 322, and the connecting member 4 may be a bolt. The bolt may sequentially pass through the first mounting hole 111a1 and the second mounting hole 322a and be screwed with a nut, thereby fixing the connecting portion 322 on the inner peripheral wall of the box body 11. It should be noted that the fixing method of the heat conducting member 3 is not unique. For example, the connecting portion 322 and the box body 11 may also be connected together by riveting.

[0079] As Figures 2 - 4 shown, according to some embodiments of the present invention, the electronic control assembly 100 may further include a support seat 124 for supporting the inductor 122. The support seat 124 may be provided on the circuit board 121. The heat conducting member 3 may be located between the inductor 122 and the support seat 124. The support portion 321 may be provided on the upper surface of the support seat 124, and the connecting portion 322 may be connected to the side wall of the support seat 124, thereby making the cooperation structure between the inductor 122 and the circuit board 121 more firm. Optionally, the support seat 124 may be connected to the circuit board 121 by screw connection.

[0080] Next, refer to Figures 2 - 5 A specific embodiment is used to describe in detail the cooperation structure of the inductor 122, the heat conducting member 3, and the support seat 124 of the present invention.

[0081] As Figure 2 shown, the support seat 124 is formed into a frame structure formed by a cuboid, and the support seat 124 is screwed to the circuit board 121. The support seat 124 is provided with a placement space. The side of the support seat 124 close to the box body 11 (such as Figure 2On the front side (side wall) as shown, a third mounting hole 124a is provided, and the third mounting hole 124a is a threaded hole. The heat conducting member 3 includes a metal part 32 and an insulating part 31 with a split design. The metal part 32 includes a support part 321 and a connecting part 322. The support part 321 is arranged in the placement space, the insulating part 31 is placed on the support part 321, and the inductor 122 is arranged on the insulating part 31. The connecting part 322 extends downward relative to the support part 321, and a second mounting hole 322a is provided on the connecting part 322, which is arranged opposite to the third mounting hole 124a, and the second mounting hole 322a is a through hole. The inductor 122 is formed in a disc shape. A first placement groove 321a recessed downward is provided on the support part 321, and a second placement groove 311 recessed downward is provided on the insulating part 31. The insulating part 31 is arranged in the first placement groove 321a, and a part of the inductor 122 is received in the second placement groove 311.

[0082] As Figure 5 As shown, an inwardly recessed mounting part 111a is provided on the box body 11, and a first mounting hole 111a1 is provided on the mounting part 111a, and the first mounting hole 111a1 is a through hole. In the front-rear direction, the first mounting hole 111a1 is arranged opposite to the second mounting hole 322a and the third mounting hole 124a. The connecting member 4 passes through the first mounting hole 111a1 and the second mounting hole 322a in sequence and extends into the third mounting hole 124a. The connecting member 4 is threadedly connected to the third mounting hole 124a, whereby the support seat 124, the heat conducting member 3 and the box body 11 can be connected together, and the heat conducting member 3 is in close contact with the inner peripheral wall of the box body 11. Thus, through the above arrangement, not only can the fixing structure of the heat conducting member 3 be made more firm, but also the heat conducting member 3 can be in close contact with the box body 11, and the heat conduction efficiency of the heat conducting member 3 can be improved.

[0083] According to some embodiments of the present invention, the radiator 2 can be in contact with the box body 11, whereby the heat dissipation efficiency of the electronic control assembly 100 can be improved. Specifically, the heat conducting member 3 can transfer the heat generated by the inductor 122 to the radiator 2 and / or the box body 11, and the heat generated by the control component 123 can be transferred to the radiator 2. Since the radiator 2 is in contact with the box body 11, heat can be propagated between the box body 11 and the radiator 2, whereby the heat dissipation efficiency of the electronic control assembly 100 can be increased. A part of the heat can be transferred to the liquid storage tank 200 through the radiator 2, and the liquid storage tank 200 can exchange heat with the radiator 2. When a part of the heat is propagated on the box body 11, heat exchange can be completed with the air flow. Thus, through the above arrangement, the heat dissipation efficiency of the inductor 122 and the control component 123 can be greatly improved.

[0084] As Figure 10As shown, in some embodiments of the present invention, the box body 11 may include a first housing 111 and a second housing 112. The first housing 111 may cooperate with the second housing 112 to define an installation space for the electric control device 12. An assembly hole 111b may be provided on the first housing 111. The radiator 2 may pass through the assembly hole 111b and extend into the installation space to at least contact the control component 123. Thereby, the structural design of the box body 11 can be made simpler and more convenient for the assembly of the electric control assembly 100.

[0085] Optionally, the first housing 111 and the second housing 112 may be connected together by a snap-fit method, or the first housing 111 and the second housing 112 may also be assembled together by a screw connection method.

[0086] In Figure 10 In the specific example shown, a sealing ring 113 may also be provided between the radiator 2 and the assembly hole 111b. The sealing ring 113 can seal the assembly gap between the radiator 2 and the first housing 111. Thereby, the mating structure between the radiator 2 and the box body 11 can be made more compact, preventing the condensate in the air conditioner from entering the box body 11 through the assembly gap between the radiator 2 and the first housing 111, and playing a good protective role for the electric control device 12.

[0087] The air conditioner according to an embodiment of the present invention includes the electric control assembly 100 according to the above embodiment of the present invention.

[0088] In the air conditioner according to an embodiment of the present invention, by providing the above electric control assembly 100, a heat conducting member 3 is provided in the electric control assembly 100. The heat conducting member 3 can transfer the heat generated by the inductor 122 to the box body 11 and / or the radiator 2. Thereby, on the basis of not affecting the sealing performance of the electric control box assembly 1, it can play a role in quickly dissipating the heat of the inductor 122, ensuring the normal operation of the electric control assembly 100, and further improving the running stability of the air conditioner.

[0089] In some embodiments of the present invention, the air conditioner may be an outdoor unit of the air conditioner, thereby making the operation of the outdoor unit of the air conditioner more stable. Of course, it can be understood that the air conditioner may also be a window air conditioner, a mobile air conditioner, etc.

[0090] Such as Figures 9 - 10As shown, in a specific example of the present invention, the outdoor unit of the air conditioner includes a housing (not shown in the figure), a compressor 300, a liquid storage tank 200, and an electric control device 12. The compressor 300 is connected to the liquid storage tank 200, and both the compressor 300 and the liquid storage tank 200 are arranged inside the housing. The electric control assembly 100 is arranged on the outer peripheral wall of the liquid storage tank 200, and the electric control assembly 100 can be electrically connected to the compressor 300 to control the working state of the compressor 300. Among them, the electric control assembly 100 includes an electric control box assembly 1, a radiator 2, and a heat conducting member 3. The electric control box assembly 1 includes a box body 11 and an electric control device 12 arranged inside the box body 11. The electric control device 12 includes a circuit board 121, control components 123, and an inductor 122.

One end of the heat conducting member 3 is connected to the inductor 122, and the other end of the heat conducting member 3 is connected to the box body 11.

[0091] When the outdoor unit of the air conditioner is working, the control components 123 can transfer the heat generated by them to the radiator 2. The radiator 2 can transfer the heat from the control components 123 to the outer surface of the liquid storage tank 200. The temperature of the outer surface of the liquid storage tank 200 is relatively low, and the temperature of the outer surface of the liquid storage tank 200 can be used to cool the control components 123. The heat conducting member 3 can transfer the heat generated by the inductor 122 to the box body 11, and the heat on the box body 11 can be exchanged with the air flow by natural convection, thereby playing a role in cooling the inductor 122.

[0092] The following refers to Figures 1 - 10 Describe in detail the electric control assembly 100 according to a specific embodiment of the present invention. The electric control assembly 100 can be arranged on the liquid storage tank 200 inside the outdoor unit of the air conditioner. It should be understood that the following description is only exemplary and not a specific limitation of the present invention.

[0095] The electronic control device 12 includes a circuit board 121, control components 123, an inductor 122, and a capacitor 125.

The inductor 122 and the capacitor 125 are arranged on the same side of the IPM module, and the inductor 122 and the capacitor 125 are spaced apart in the length direction of the circuit board 121 (such as Figure 1 and Figure 4 shown in the front-back direction). The inductor 122 is formed in a disc shape, the inductor 122 is spaced apart from the IPM module, and a heat conducting member 3 is provided below the inductor 122.

[0096] One end of the radiator 2 is fixed on the liquid storage tank 200 by means of welding connection, and the other end of the radiator 2 extends into the box body 11 through the assembly hole 111b and contacts the IPM module. A sealing ring 113 is provided between the radiator 2 and the assembly hole 111b, and the sealing ring 113 is used to seal the assembly gap between the radiator 2 and the first housing 111.

[0097] As Figure 3 shown, a support seat 124 is provided on the circuit board 121. The support seat 124 is formed in a rectangular frame structure. The support seat 124 is connected to the circuit board 121 by screws. A placement space is provided on the support seat 124. A third mounting hole 124a is provided on a side wall of the support seat 124 close to the box body 11, and the third mounting hole 124a is a threaded hole.

[0098] The heat conducting member 3 includes a metal part 32 and an insulating part 31 with a split design. The metal part 32 includes a support part 321 and a connecting part 322. The support part 321 is arranged in the placement space, the insulating part 31 is placed on the support part 321, and the inductor 122 is arranged on the insulating part 31. The connecting part 322 extends downward relative to the support part 321. A second mounting hole 322a is provided on the connecting part 322 and is arranged opposite to the third mounting hole 124a. The second mounting hole 322a is a through hole. Among them, a first placement groove 321a recessed downward is provided on the support part 321, a second placement groove 311 recessed downward is provided on the insulating part 31, the insulating part 31 is arranged in the first placement groove 321a, and a part of the inductor 122 is received in the second placement groove 311.

[0099] As Figure 5As shown in the figure, a recessed mounting portion 111a is provided on the box body 11. A first mounting hole 111a1 is provided on the mounting portion 111a, and the first mounting hole 111a1 is a through hole. In the front-back direction, the first mounting hole 111a1 is disposed opposite to the second mounting hole 322a and the third mounting hole 124a. A connecting member 4 is sequentially passed through the first mounting hole 111a1 and the second mounting hole 322a and extends into the third mounting hole 124a. The connecting member 4 is threadedly connected to the third mounting hole 124a. Thus, the support seat 124, the heat conducting member 3 and the box body 11 can be connected together, and the heat conducting member 3 is closely attached to the inner peripheral wall of the box body 11.

[0100] When the electric control device 12 operates, both the control component 123 and the inductor 122 can generate a large amount of heat. The control component 123 can transfer the heat to the radiator 2, and the radiator 2 can transfer the heat from the control component 123 to the outer surface of the liquid storage tank 200. The temperature of the outer surface of the liquid storage tank 200 is relatively low, and the temperature of the outer surface of the liquid storage tank 200 can be used to cool the control component 123. The heat conducting member 3 can transfer the heat generated by the inductor 122 to the box body 11. A part of the heat on the box body 11 can be exchanged with the air flow by natural convection, and another part of the heat on the box body 11 can be transferred to the radiator 2. Thus, through the above settings, the heat dissipation efficiency of the electric control device 12 can be improved without affecting the sealing effect of the electric control assembly 100. It can not only prevent the condensate water in the outdoor unit of the air conditioner from flowing onto the electric control device 12, but also enable the inductor 122 and the control component 123 to operate at a suitable working temperature, thereby improving the operation stability of the outdoor unit of the air conditioner.
