Embodiment 1

[0026] An integrated drive controller for a vehicle air-conditioning compressor, including a control circuit, a power device 27 and a heat sink 21 of the control circuit, such as figure 1 and figure 2 As shown, the outer side of the cooling part 21 is attached to the outer side of the housing 11 in the low-pressure area of ​​the compressor 1; Device 27 dissipates heat. Since the temperature of the low-pressure intake area of ​​the compressor 1 is relatively low, it can effectively help the drive controller 2 to dissipate heat, thereby solving the heat dissipation problem of the drive controller 2 .

[0027] Wherein, the heat dissipation part 21 is a part of the casing of the drive controller 2 used to adhere to the casing of the low pressure area of ​​the compressor 1 .

[0028] Wherein, the compressor casing 11 and the drive controller heat sink 21 are fastened and connected by bolts 28, such as figure 1 As shown, the cooling part 21 of the drive controller 2 is closely a...

Embodiment 2

[0034] The present invention also provides another integrated drive controller for a vehicle air conditioner compressor, including a control circuit, a power device 27 and a heat sink 21 of the control circuit, such as image 3 and Figure 4 As shown, the outer side of the heat dissipation part 21 is attached to the outer side of the housing 11 in the low pressure area of ​​the compressor 1, and the heat dissipation part has a through hole 21a leading to the outer side of the housing in the low pressure area; the power device 27 passes through the heat dissipation part 21 The through hole 21a of the compressor 1 is attached to the outer side of the housing 11 in the low pressure area, and the low temperature in the low pressure area of ​​the compressor 1 is used to dissipate heat from the power device 27 .

[0035] Wherein, the power device 27 of the drive controller 2 is fixed on the outside of the housing 11 in the low-pressure area of ​​the compressor 1 by bolts, and the co...

Abstract

The invention discloses an integral type drive controller for a vehicle air compressor, which mainly solves the problems of difficult heat radiation, great requirement for assembly space, long harness and the like of the drive controller of the traditional air compressor. The integral type drive controller comprises a control circuit, a power device of the control circuit and a heat radiating part, wherein the outer side of the heat radiating part is attached to the outer side of a low-pressure area shell of the air compressor; the power device is attached to the inner side of the heat radiating part so that the heat radiating part radiates the heat of the power device by using low temperature of the low-pressure area of the air compressor. Alternatively, the outer side of the heat radiating part is attached to the outer side of the low-pressure area shell of the air compressor, and the heat radiating part is provided with a through hole leading to the outer side of the low-pressure area shell; and the power device penetrates through the through hole of the heat radiating part and is attached to the outer side of the low-pressure area shell, and the heat of the power device is radiated by using low temperature of the low-pressure area of the air compressor. Heat radiation of the drive controller is increased, and the assembly space is reduced.

Description

technical field [0001] The invention relates to an air-conditioning compressor, in particular to a drive controller which can use the low temperature in the low-pressure area of ​​the compressor to dissipate heat from the drive controller. Background technique [0002] There are two drive modes for vehicle air conditioner compressors. The traditional driving method is that the engine transmits power through a belt; the new driving method is driven by a vehicle-mounted DC motor. The compressor driven by the on-board DC motor has a built-in DC motor, and its work is controlled by the driver. Usually, the drive controller and the electric compressor are installed separately, which causes problems such as difficult heat dissipation of the drive controller, large assembly space requirements, and increased wiring harness, which affects the electrical performance and assembly process of the drive controller. [0003] Publication No. CN 200978794Y relates to a controller for elect...
