The automobile evaporator unit is a component of the air-conditioning system. Its function is that the low-temperature condensed gas passes through the evaporator, exchanges heat with the outside air, liquefies and absorbs heat, and achieves the effect of cooling. The evaporator unit is generally installed on the passenger side of the instrument panel, including the evaporator housing, evaporator core, and some models also include expansion valves and damper control motors. The out case of our evaporator is brand-new ABS material, tough and not easy to break. Both the motor and the impeller have passed the balance test, which effectively reduces the noise of the product and increases the service life of the product (the service life of the motor is more than 2600 hours). The built-in evaporator core adopts a stacked structure, 32 tubes, copper tubes and aluminum fins to increase the heat transfer area on the refrigerant side and enhance the cooling and heating efficiency. All plastic parts are tested for hardness. Zero customer complaints in terms of quality. The product has the advantages of large air volume, large cooling capacity, uniform air supply, convenient adjustment, beautiful appearance, and convenient installation. Expansion valves have domestic high-quality brands and Japanese imported brands, which can be selected according to customer requirements.
