Embodiment Construction
[0043] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0044] In the refrigeration system, the electric valve is used to control the flow of refrigerant. By adjusting the flow of refrigerant, it can control the superheat of the system. The electric valve controls the flow of refrigerant based on the electric signal to control the opening. In order to improve the flow control accuracy, electric valves are gradually used as throttling components in automotive air conditioning systems, heat pump systems, and battery cooling systems.
[0045] figure 1 It is a schematic block diagram of an embodiment of a refrigeration system. In this embodiment, the refrigeration system includes an air-conditioning system and a battery cooling system. The air-conditioning system includes a compressor 100, a condenser 200, a first electric valve 1, and an evaporator 300; the air-conditioning system During operation, the refr...

The invention relates to an electric valve and a heat management assembly. The electric valve comprises a valve body, a valve element, a rotor assembly, a stator assembly and a circuit board. The electric valve is provided with a valve port, the rotor assembly can drive the valve element to move relative to the valve port, and the valve element can move relative to the valve port and adjust the opening of the valve port. The electric valve also comprises a conducting part, the conducting part and the valve body can conduct electricity, at least part of the conducting part is arranged between the circuit board and the valve body, at least part of the conducting part is electrically connected to a reference stratum of the circuit board, at least part of the conducting part is in contact withthe valve body, and electricity can be conducted between the reference stratum of the circuit and the valve body through the conducting part. Thus, influence of static electricity on the electric valve is reduced favorably, so that the electromagnetic compatibility of the electric valve is improved favorably.
