[0045] Combination Figure 1 , Figure 2 and Figure 3 The air conditioner driving device of the utility model includes a circuit board 10 and a heat dissipation assembly. A first component assembly is arranged on one side of the circuit board 10, and a second component assembly is arranged on the other side of the circuit board 10. The first component assembly includes at least one insulated gate bipolar transistor and at least one diode, and the second component assembly includes at least one inductor and at least one capacitor. The power of the first component assembly is greater than the power of the second component.

[0046] Among them, the insulated gate bipolar transistor, the diode, the inductor device and the capacitor device constitute the power factor correction component.

[0047] More specifically, the first component assembly includes a first rectifier 101a, a second rectifier 101b, a first switch tube 102a, a second switch tube 102b, a third switch tube 102c, and a first diode 103a, a second diode 103b, a third diode 103c, and a first inverter 104; the second component assembly includes a first inductor 105a, a second inductor 105b, a third inductor 105c, and a first capacitor 106a, a second capacitor 106b, a third capacitor 106c, and a fourth capacitor 106d. The air-conditioning driving device of this embodiment integrates multiple switch tubes, multiple diodes, two rectifiers, an inverter, and multiple capacitors, multiple inductors, and multiple capacitors on both sides of the circuit board 10. Compared with the dispersed arrangement of multiple different components, the air-conditioning driving device of this embodiment reduces the external dimensions of the circuit board 10, can make the volume of the air-conditioning driving device smaller, and save the internal space of the air conditioner.

[0048] The air conditioning driving device of this embodiment concentrates components with relatively high power and high heat generation in a first component assembly, so that the power of the first component assembly is greater than the power of the second component assembly, which is beneficial for concentrated heat dissipation of one or more components with relatively high power.

[0049] Among them, the heat dissipation component can be arranged on one side of the first component assembly of the circuit board 10, and the first component assembly is close to the heat dissipation component to dissipate heat for the first component assembly. The heat dissipation component of the air-conditioning driving device in this embodiment can adopt liquid cooling; when the first component assembly or the second component assembly dissipates less heat during operation, air cooling or natural heat dissipation can also be adopted.

[0050] In other embodiments, the heat dissipation component may be provided on one side of the circuit board 10 located at the second component assembly, and the second component assembly may be placed against the heat dissipation component to dissipate heat for the second component assembly, thereby dissipating heat for the first component assembly and the second component assembly at the same time.

[0051] In one of the embodiments, in an air-conditioning driving device, a refrigeration assembly and a heat conductor are arranged in the heat dissipation assembly, and the heat conductor is respectively connected to the first component assembly and the refrigeration assembly. The heat generated by the operation of the first component assembly is conducted to the refrigeration assembly through the heat conductor, wherein the refrigeration assembly includes a refrigerant pipe assembly, and a refrigerant medium for conducting heat is arranged in the refrigerant pipe assembly.

[0052] The heat generated by the first component assembly is taken away by the refrigerant medium in the refrigerant pipe assembly 13 of the refrigeration assembly.

[0053] Similarly, when the above-mentioned heat dissipation assembly is arranged on one side of the circuit board 10 located at the second component assembly, and the heat conductor is respectively connected to the second component assembly and the refrigeration assembly, the heat generated by the operation of the second component assembly is conducted to the refrigeration assembly through the heat conductor, and the refrigerant medium in the refrigerant pipe assembly 13 in the refrigeration assembly takes away the heat generated by the second component assembly.

[0054] In order to facilitate heat dissipation of the first component assembly and the second component assembly, the first component assembly and the second component assembly may be placed against the heat conducting member.

[0055] In one of the embodiments, the refrigeration component includes a refrigerant pipe assembly 13. The refrigerant in the refrigerant pipe assembly 13 carries away the heat generated by the first component assembly or the second component assembly during circulation. In order to further improve the heat dissipation efficiency, the refrigerant can also form a circulating circulation loop in the refrigerant pipe assembly 13, so as to continuously dissipate heat for the first component assembly or the second component assembly.

[0056] The air-conditioning driving device in this embodiment takes away the heat generated by the first component assembly and the second component assembly by setting a refrigerant pipe assembly 13 in the heat dissipation assembly. Compared with the existing air-cooling heat dissipation method, the refrigerant pipe assembly 13 can take the heat out of the air-conditioning driving device and has the characteristic of high heat dissipation efficiency.

[0057] In one embodiment of the utility model, only the first component assembly can be placed against the heat conductive part of the heat dissipation assembly, and the heat dissipation assembly dissipates heat for the first component assembly, and the second component assembly adopts air cooling or natural heat dissipation, or a plurality of fins for heat dissipation can be arranged in the second component assembly; the second component assembly can also be placed against the heat conductive part of the heat dissipation assembly, and the heat dissipation assembly dissipates heat for the second component assembly; and a plurality of fins for heat dissipation can also be arranged in the first component assembly.

[0058] The air-conditioning driving device of the utility model divides a plurality of different components into a first component assembly and a second component assembly, which are respectively arranged on both sides of a circuit board 10. Different types of components can be arranged in zones. For example, components that generate a lot of heat during operation can be concentrated on one side of the circuit board 10, or arranged in a specific area of ​​the circuit board 10. The heat dissipation assembly can be used to dissipate heat from a plurality of components in a specific area, thereby taking away more heat in a concentrated manner, which is beneficial to improving the heat dissipation efficiency of the air-conditioning radiator.

[0059] The air-conditioning driving device of the utility model arranges the first component assembly and the second component assembly of different powers on both sides of the circuit board 10 respectively, which can effectively utilize the limited space of the circuit board 10, and is conducive to setting more components on one circuit board 10. It should be noted that the air-conditioning driving device of the utility model centrally sets a plurality of high-power components, which causes more heat to be concentrated in one area of ​​the circuit board. By adopting the refrigerant pipe assembly 13 and the heat conductor, more heat in one area of ​​the circuit board can be dissipated in time, reducing the influence of high temperature on the normal operation of the components.

[0060] When the air-conditioning driving device of the utility model is arranged in the air-conditioning driving device, the components in the air-conditioning driving device are concentratedly arranged and the overall volume is small, which saves the effective space in the air-conditioning and is conducive to the reasonable arrangement of different parts in the air-conditioning, such as increasing the effective area of ​​the heat exchanger, and reducing the volume of the air-conditioning chassis, so as to appropriately reduce the external dimensions of the air-conditioning and reduce the space occupied by the air-conditioning.

[0061] Combination Figure 1In one embodiment of the utility model, the circuit board 10 is provided with a first connection area 21, and the first component assembly is electrically connected to the circuit board 10 in the first connection area 21. The circuit board 10 is also provided with a second connection area 22, and the second component assembly is electrically connected to the circuit board 10 in the second connection area 22. The first component assembly and the second component assembly are respectively arranged in different areas, which can reduce the mutual influence between the first component assembly and the second component assembly. In the air-conditioning driving device in this embodiment, the first connection area 21 and the second connection area 22 can be arranged on the same side of the circuit board 10 and are arranged at intervals. The first connection area 21 and the second connection area 22 can also be arranged on both sides of the circuit board 10 to reduce the interference of the first component assembly on the second component assembly, or the interference of the second component assembly on the first component assembly.

[0062] In one embodiment of the present invention, the first component assembly and the second component assembly are both welded to the circuit board 10. More specifically, the first component assembly and the second component assembly are connected to the circuit board 10 by copper foil welding. The welding method is used to ensure that the first component assembly and the second component assembly have a high connection strength with the circuit board 10. Therefore, the air-conditioning driving device in this embodiment reduces the wiring harness connection between the first component assembly and the circuit board 10 and between the second component assembly and the circuit board 10, while fixing the first component assembly and the second component assembly to the circuit board 10 in a more secure manner, which is also beneficial to the modular design within the air-conditioning driving device, and is convenient for later maintenance and replacement.

[0063] In some embodiments of the utility model, the first connection area 21 and the second connection area 22 on the circuit board 10 are located on the same side of the circuit board 10. Setting the first connection area 21 and the second connection area 22 on the same side can shorten the routing distance on the circuit board 10 and prevent the weakening or distortion of the electrical control signal between the first component assembly and the second component assembly. The air-conditioning driving device in this embodiment respectively arranges the first component assembly and the second component assembly on both sides of the circuit board 10. At the same time, the first connection area and the second connection area are located on the same side of the circuit board, which can prevent the first component assembly and the second component assembly from being affected by other components or causing interference to other devices.

[0064] The first connection area and the second connection area are located on the same side of the circuit board and are close to each other, which can also reduce the attenuation of the signal during the transmission process between the first component assembly and the second component assembly.

[0065] In some embodiments of the present invention, the heat dissipation component is arranged near the middle area of ​​the circuit board 10. The heat dissipation component can support the circuit board 10 to prevent the circuit board 10 from being deformed during the installation and welding processes, because the heat dissipation component is arranged in the middle area of ​​the circuit board 10 to act as a reinforcing rib.

[0066] Specifically, combined Figure 1 , Figure 2 and Figure 3 The heat dissipation component is extended along the middle area of ​​the circuit board 10, which can reduce the warping and deformation of the circuit board 10. The extension path of the circuit board 10 can be arranged according to actual needs. For example, the heat dissipation component is extended along the diagonal direction of the circuit board 10. The heat dissipation component can also be arranged in an arc shape according to the external dimensions of the circuit board 10. The heat dissipation component can also be arranged in multiple parts, with the multiple parts being arranged at an angle, or two adjacent parts being in a broken line shape.

[0067] In some embodiments of the utility model, the heat dissipation component of the air-conditioning driving device includes a refrigerant pipe assembly 13 and a heat conductor. When the first component assembly is attached to the heat conductor, the refrigerant medium in the refrigerant pipe assembly 13 can take away the heat generated by the first component assembly, and the first component assembly can also be fixed on the heat conductor to improve the stability and connection strength of the first component assembly. More specifically, the first component assembly can be fixed on the heat conductor by a fastener 109.

[0068] Similarly, the second component assembly can be placed against the heat conductor, and the refrigerant medium in the refrigerant pipe assembly 13 can take away the heat generated by the second component assembly, thereby fixing the second component assembly on the heat conductor to improve the stability and connection strength of the second component assembly. The second component assembly and the heat conductor can be connected via fasteners 109.

[0069] Combination Figure 3 In one embodiment of the utility model, the heat conductive member further includes a first heat conductive member 12a and a second heat conductive member 12b, the refrigerant pipe assembly 13 is located between the first heat conductive member 12a and the second heat conductive member 12b, and the first heat conductive member 12a and the second heat conductive member 12b are both arranged in close contact with the refrigerant pipe assembly 13.

[0070] like Figure 3 and Figure 4 As shown, the first heat conductive member 12a and the second heat conductive member 12b together form a cavity suitable for the refrigerant pipe assembly 13 to pass through, wherein the first heat conductive member 12a and the second heat conductive member 12b at least partially surround the refrigerant pipe assembly 13.

[0071] The first component assembly may be disposed on the first heat conducting member and connected and fixed by a fastener 109 .

[0072] Thermally conductive material can also be applied between the refrigerant tube assembly 13 and the first heat conductor 12a and between the refrigerant tube assembly 13 and the second heat conductor 12b. The space between the first heat conductor 12a and the refrigerant tube assembly 13 is filled with thermally conductive material, and the space between the second heat conductor 12b and the refrigerant tube assembly 13 is filled with thermally conductive material. This improves the thermal conductivity between the first heat conductor and the refrigerant tube assembly 13 and between the second heat conductor and the refrigerant tube assembly 13, so that the heat generated by the first component assembly and the second component assembly is promptly conducted to the refrigerant tube assembly 13 and carried away by the refrigerant medium in the refrigerant tube assembly 13.

[0073] A single U-tube or a double U-tube may be provided in the refrigerant tube assembly 13 to increase the flow path of the refrigerant medium and improve the heat dissipation effect.

[0076] The housing may also be configured to be closed, and the closed housing may protect the circuit board 10 and the first component assembly and the second component assembly.

[0077] In one embodiment, the air conditioner driving device provided by the utility model can be placed vertically or horizontally, such as Figure 3 and Figure 4 As shown, the air conditioning driving device further includes a connecting member 15 , which is connected to the first heat conducting member or the second heat conducting member, and the air conditioning driving device is connected to the air conditioner via the connecting member 15 .

The air-conditioning driving device in this embodiment is suitable for components with higher power. The inductor device or the capacitor device is arranged at the edge area of ​​the circuit board 10, which is far away from other components to reduce interference with the electric control signal.

[0081] In an embodiment of the present invention, the number of insulated gate bipolar transistors is N1, the number of diodes is N2, and the number of inductor devices is N3, wherein the values ​​of N1, N2 and N3 are the same.

[0082] like Figure 1 As shown, the first component assembly includes a first rectifier device 101a, a second rectifier device 101b, a first switch tube 102a, a second switch tube 102b, a third switch tube 102c, and a first diode 103a, a second diode 103b, a third diode 103c, and a first inverter 104, which are arranged in a straight line. The number of rectifier devices in this embodiment is greater than or equal to 1, and the number of groups of switch tubes and diodes in the power factor correction device is greater than or equal to 2. In this embodiment, the number of groups of switch tubes and diodes is 3.

[0083] The second component assembly includes a first inductor 105a, a second inductor 105b, a third inductor 105c, a first capacitor 106a, a second capacitor 106b, a third capacitor 106c, a fourth capacitor 106d, and a common-mode inductor 100; the inductor and the capacitor are located on the same side of the connection position between the power device and the circuit board 10. The number of inductors in this embodiment is 3, the number of switch tubes and diode groups is consistent, and the number of capacitors is set according to actual needs.

[0085] In some embodiments of the present invention, the first component group further includes a rectifier component group and a first power component group, and the weak current components, the rectifier component and the first power component are arranged in the first connection area 21 along the extension direction of the heat dissipation component, wherein the first power component includes a first inverter 104, Figure 1The weak current components, the rectifier assembly and the first power assembly are shown to be arranged in a straight line.
