Evaporation is the physical process of converting a liquid to a gaseous state. Generally speaking, an aluminum air conditioner evaporator is an object that converts a liquid substance into a gaseous state. There are a large number of evaporators in the industry, and the evaporator used in the refrigeration system is one of them. The evaporator is a very important part of the four major components of refrigeration. The low-temperature condensed liquid passes through the evaporator, exchanges heat with the outside air, vaporizes and absorbs heat, and achieves the effect of refrigeration. The evaporator is mainly composed of two parts: a heating chamber and an evaporation chamber. The heating chamber provides the heat needed for evaporation to the liquid, which promotes the boiling and vaporization of the liquid; the evaporation chamber completely separates the gas-liquid two phases.
