In the thermal management system of a car, it is roughly composed of an electronic water pump, solenoid valve, compressor, PTC heater, electronic fan, expansion kettle, evaporator, and condenser.
Electronic water pump: a mechanical device for conveying liquid or pressurizing liquid. It transfers the mechanical energy of the prime mover or other external energy to the liquid, increases the energy of the liquid, and conveys the liquid. The operating principle is to judge according to the current state of the power or other components, and control the flow rate by controlling the flow through the water pump. According to different flow rates, heat can be taken away to maintain temperature stability.
Solenoid valve: an electronically controlled valve, which has two-way and three-way valves. The refrigerant flowing out of the condenser outlet is in a high-temperature and high-pressure liquid state. In order to reduce the saturation temperature of the liquid refrigerant, its pressure needs to be reduced. At the same time, in order to keep the flow within a suitable range, before the refrigerant enters the evaporator, it needs to be throttled by controlling the valve opening.
Compressor: The low-pressure and low-temperature refrigerant gas is pushed and compressed to do work on the gaseous refrigerant, so that it can produce changes in pressure and temperature, thus becoming a high-temperature and high-pressure gaseous refrigerant.
Condenser: Cool the high-temperature refrigerant. After the refrigerant is discharged from the compressor, it is in a high-temperature and high-pressure state. At this time, it needs to be cooled down and the process of the refrigerant changing from gas to liquid is completed.
