specific Embodiment approach

[0031] Such as Figure 1 to Figure 4 The automobile air-conditioning system shown includes an evaporator 1 and an electronic expansion valve 2 connected through pipelines. The electronic expansion valve 2 includes a coil 200 and a valve body 201. The coil 200 is fixedly installed on the valve body 201, and the electronic expansion valve 2 is fixedly installed on the On the evaporator 1 , the first port of the electronic expansion valve 2 is fixedly installed outside the evaporator 1 through the first pipe 400 made of rigid material, and the first port of the electronic expansion valve 2 communicates with the third pipe 100 of the evaporator 1 .

[0032] The automobile air-conditioning system of the present invention fixes the electronic expansion valve next to the evaporator by using the base, so that the electronic expansion valve is in a lower temperature working environment, and the structure of the automobile air-conditioning system is greatly reduced and becomes compact ,...

Abstract

The invention relates to an automobile air-conditioning system. The automobile air-conditioning system includes an evaporator (1) and an electronic expansion valve (2) communicated through pipelines. The electronic expansion valve (2) includes a coil (200) and a valve body (201 ), the coil (200) is fixedly installed on the valve body (201), the electronic expansion valve (2) is fixedly installed on the evaporator (1), and the first interface of the electronic expansion valve (2) The first pipe (400) made of rigid material is fixedly installed on the outside of the evaporator (1), and the first port of the electronic expansion valve (2) communicates with the third pipe (100) of the evaporator (1) . The automobile air-conditioning system of the invention has compact structure design, can effectively cool the electronic expansion valve, has high system strength, stable refrigerant transmission and high safety.

Description

technical field [0001] The invention relates to the field of air conditioning, and more specifically relates to an automobile air conditioning system. Background technique [0002] With the higher and higher requirements of automobile energy saving, the energy saving of automobile air conditioning system is also particularly important. In automobile air-conditioning systems, most of the existing throttling mechanisms are thermal expansion valves and short throttle tubes. The traditional throttling mechanism is not ideal in terms of superheat control and overall system energy saving, while the electronic expansion valve has strong advantages in superheat control and energy saving due to its accurate control. [0003] However, there are many problems in the application of electronic expansion valves in automotive air conditioners. The main point is that because electronic expansion valves are electrical components, it is difficult to meet the temperature resistance requiremen...
