The heat conducting member 3 can exchange heat with the inductor 122, and the heat conducting member 3 can also conduct heat generated by the inductor 122, so that the heat can be prevented from being accumulated in the inductor 122, and a quick heat dissipation effect can be achieved on the inductor 122.

In a specific example of the present invention, the inductance assembly may be used in an electric control device, a heat dissipation portion is provided on a housing of the electric control device, and one end of the heat conducting member 3 is connected to the heat dissipation portion. When the electric control device operates, heat generated by the inductor 122 can be transmitted to the heat dissipation part through the heat conducting part 3, and the heat dissipation part can transmit the heat from the inductor 122 to the outside of the electric control device, so that the inductor 122 and the electric control device can be quickly cooled, the electric control device can operate at a proper working temperature, and the operation stability of the electric control device can be improved.
According to the inductor assembly provided by the embodiment of the invention, the heat conducting member 3 is arranged, and the heat conducting member 3 can conduct heat generated by the inductor 122, so that heat can be prevented from being accumulated in the inductor 122, a rapid heat dissipation effect can be achieved on the inductor 122, and the normal operation of the inductor 122 can be further ensured.
As shown in fig. 2, according to some embodiments of the present invention, the inductor assembly may further include a support base 124, and the heat-conducting member 3 may be placed on the support base 124, so that the assembly of the inductor 122 and the heat-conducting member 3 may be facilitated.

For example, the inductor 122 may be formed in a disc shape, the receiving space may be formed in a fitting groove recessed downward, and the heat conductive member 3 may be formed in a circular arc shape and closely attached to an inner circumferential wall of the fitting groove. When the inductor 122 is assembled with the supporting base 124, a portion of the inductor 122 may be received in the assembly groove and closely attached to the upper surface of the heat conducting member 3. Therefore, by the arrangement, the matching structure of the inductor 122, the supporting seat 124 and the heat conducting piece 3 is firmer, and the heat conduction efficiency of the heat conducting piece 3 can be improved.
As shown in fig. 2, according to some embodiments of the present invention, the heat-conducting member 3 may include a metal portion 32 provided on the insulating portion 31, whereby the heat-conducting efficiency of the heat-conducting member 3 may be improved. It can be understood that the metal material has high heat conduction efficiency, 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 away, so that the heat dissipation efficiency of the inductor assembly can be improved.
Alternatively, the insulating portion 31 and the metal portion 32 may be a separate member, and the insulating portion 31 and the metal portion 32 may also be an integrally formed member. For example, as shown in fig. 2, the heat conducting member 3 includes an insulating portion 31 and a metal portion 32 which are separately designed, the metal portion 32 is placed on the supporting base 124, and the insulating portion 31 is located between the inductor 122 and the metal portion 32. Thus, with the above arrangement, the insulating portion 31 can prevent the electric leakage phenomenon between the inductor 122 and the metal portion 32, and the insulating portion 31 can transfer the heat generated by the inductor 122 to the metal member.

To ensure proper operation of the electronic control device 12, the electronic control device 12 needs to be cooled. The heat sink 2 may be used to dissipate heat of the control component 123, so that the operating temperature of the control component 123 may be reduced, and normal operation of the control component 123 may be ensured.
The heat-conducting member 3 may serve to transfer heat, and the heat-conducting member 3 may be provided with an insulating portion 31, where the insulating portion 31 has functions of conducting heat and preventing electrical conduction, so that the normal operation of the inductor 122 may be ensured. The heat conducting member 3 can be in contact with the heat dissipating portion of the case 11, the heat conducting member 3 can also be in contact with the heat sink 2, and the heat conducting member 3 can also be in contact with the heat dissipating portion of the case 11 and the heat sink 2. When heat-conducting member 3 contacts with the heat dissipation portion on box body 11, heat-conducting member 3 can cool down the heat dissipation portion by adopting the natural convection mode on transferring the heat generated by inductor 122 to the heat dissipation portion on box body 11, thereby playing a role in cooling inductor 122. When the heat conducting member 3 contacts the heat sink 2, the heat conducting member 3 can transfer heat generated by the inductor 122 to the heat sink 2, so that the inductor 122 can be dissipated through the heat sink 2.
From this, through the above-mentioned setting, adopt on heat-conducting member 3 can be with the heat transfer of the inductance 122 production in the box body 11 to heat dissipation part and/or radiator 2 on the box body 11, can dispel the heat effectively to inductance 122 on the basis that does not influence the box body 11 sealing performance, not only can prevent that the comdenstion water in the air conditioner from flowing into electrically controlled device 12 on, can also make inductance 122 move under suitable operating temperature, can promote the operation stationarity of air conditioner.
Alternatively, the heat dissipation portion on the box 11 may be a part of the box 11, and the heat dissipation portion may also be a heat dissipation device, and the heat dissipation portion may be disposed on the outer peripheral wall of the box 11 and may cool the heat conducting member 3, so as to reduce the temperature of the inductor 122.
The electric control device 12 of the present invention will be described in detail in one specific embodiment with reference to fig. 1 and 10.
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. The circuit board 121 is provided with a control component 123, an inductor 122 and a capacitor 125, 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 heat sink 2. The inductor 122 and the capacitor 125 are disposed on the same side of the IPM module (the left side as viewed in fig. 4), and the inductor 122 and the capacitor 125 are disposed at intervals in the length direction of the circuit board 121 (the front-back direction as viewed in fig. 1 and 4). The inductor 122 is formed in a disc shape, the inductor 122 and the IPM module are spaced apart, the heat conducting member 3 is disposed below the inductor 122, the insulating portion 31 of the heat conducting member 3 is in contact with the inductor 122, and one end of the heat conducting member 3 is connected to the heat dissipating portion of the case 11.
When the electronic control device 12 works, heat generated by the IPM module may be transferred to the radiator 2, the radiator 2 may transfer heat from the IPM module to the outer surface of the liquid storage tank 200, and the IPM module may be cooled by using the temperature of the outer surface of the liquid storage tank 200.

It should be noted that the heat sink 2 may be in direct contact with the outer peripheral wall of the liquid storage tank 200, or the heat sink 2 may be in indirect contact with the outer peripheral wall of the liquid storage tank 200, and may be selectively arranged according to actual installation requirements.
