What is a car evaporator box? The evaporator is a heat exchanger.

High-pressure liquid refrigerant enters the evaporator through the expansion valve. Due to the atomization effect of the expansion valve, the liquid refrigerant turns into mist, and the mist-like refrigerant turns into gas under low pressure conditions. During the conversion process, heat will be absorbed, so the evaporator is cool at this time. After the wind passes through, it becomes cool wind, achieving the purpose of cooling.

What is the use of a car evaporation box? The car air-conditioning evaporator is placed in the car. It is a direct air-cooled structure. It uses the principle that low-temperature and low-pressure liquid refrigerant needs to absorb a large amount of heat when evaporating. The heat in the air around it is taken away, thereby achieving the purpose of cooling and sending cold air into the car to cool the car. When the low-temperature and low-pressure liquid refrigerant from the throttling device evaporates, it absorbs a large amount of heat from the surrounding air, thereby achieving the purpose of cooling the interior of the car.

To put it simply, the function of the evaporation box is that high-temperature and high-pressure liquid refrigerant enters the evaporation box through the atomization of the expansion valve. As the pressure becomes smaller, the mist-like refrigerant will vaporize and become into gaseous state. During this conversion process, heat is absorbed. Therefore, the temperature on the surface of the evaporation box will become lower at this time, and the wind passing through the surface of the evaporation box will become cool wind.
