Valve body integrated module and heat pump air-conditioning system

Abstract

The invention discloses a valve body integrated module and a heat pump air conditioning system, and belongs to the technical field of automobiles. The valve body integrated module comprises a first electronic expansion valve, a dehumidification valve, a filter valve, a second electronic expansion valve, a heating valve, a first one-way valve, a second one-way valve, a first switching block and a second switching block. The first electronic expansion valve and the dehumidification valve are arranged side by side in the first direction and are connected through the first switching block and theconnecting piece, the second switching block, the filter valve and the second electronic expansion valve are arranged side by side in the first direction and connected through the connecting piece, the first one-way valve, the heating valve and the second one-way valve are arranged side by side in the second direction and connected through the connecting piece, and a preset included angle is formed between the second direction and the first direction. According to the valve body integrated module, the multiple valve bodies are integrated together through the switching blocks and the connectingpieces, and through reasonable arrangement, the integration degree is improved to a great extent, the external pipeline structure is simplified, and the installation difficulty, the installation costand the wiring harness cost are reduced.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a valve body integrated module and a heat pump air-conditioning system. Background technique [0002] The heat pump air-conditioning system is an important part of the car, which can change the temperature environment in the car so that the driver and passengers can get a good driving experience. Existing heat pump air conditioning systems are equipped with various valve bodies such as electronic expansion valves, dehumidification valves, filter valves, high-pressure check valves, and low-pressure check valves according to functional requirements, and the various valve bodies are generally distributed. And independently installed in the pipeline. Such setting not only leads to complex pipeline structure in the heat pump air-conditioning system, but also makes installation more difficult, which is not conducive to the car platform design, and more pipeline design costs are hi...

AI Technical Summary

Problems solved by technology

Such setting not only leads to complex pipeline structure in the heat pump air-conditioning system, but also makes installation more difficult, which is not conducive to the platform design of automobiles, and more pipeline design costs are high, the layout is easy to be messy, and it is not easy to maintain later

In addition, since most of the existing valve bodies are electronic valves, each electronic valve needs to be connected to the electrical wiring harness of the vehicle. Since the valve bodies are scattered, the cost of the vehicle wiring harness is relatively high
