Abstract
Description
technical field
[0001] The present invention relates to an electronic expansion valve. Background technique
[0002] The traditional air conditioning system consists of four major components, namely the compressor, the evaporator, the condenser and the throttling device. According to the different needs of the air conditioning system, the throttling device can include expansion valves and capillaries. Expansion valve can be divided into thermal expansion valve and electronic expansion valve according to the driving principle. Electronic expansion valves can be divided into electromagnetic-driven electronic expansion valves and motor-driven electronic expansion valves according to different driving methods.
[0003] The automotive air-conditioning system includes the above-mentioned four major components. In terms of the throttling device, the automotive air-conditioning system usually uses an expansion valve as the throttling device. Chinese patent application CN101551174...
