The basic requirements of the evaporator are the same as that of the condenser. Because it is placed in the car, its anti-corrosion performance is not as high as that of the condenser, but the space inside the car is limited, so the more demanding requirements are imposed on its volume.
The function of the evaporator is to evaporate the low-pressure refrigerant from the expansion valve to absorb the heat of the air inside the vehicle, thereby achieving the purpose of cooling in the vehicle. The evaporator is only required to have a tube type. Tube and cascading. At present, China's cars mainly use all-aluminum cascading and tube-and-belt evaporators. The large-sized passenger cars mainly use copper-tube aluminum-plate evaporators.
The medium-sized passenger cars are available in several forms, mainly tube-type. Air conditioners such as the Audi A6, Baolai, Honda, Buick, Sail, and Shanghai Passat all use stacked evaporators, and the air conditioners of the Santana 2000 sedan use tube-and-belt evaporators.
