Air Evaporators, Finned Tube Heat Exchangers, Flue Gas Heat Recovery, Long Service Life, Yichen Customized, Evaporation is a physical process of liquid transforming into gas. Generally speaking, an evaporator is an object that transforms a liquid into a gas. In industry, there are a large number of evaporators, among which evaporators applied in refrigeration systems are one type. The evaporator is an important component in the four major components of refrigeration, where low-temperature condensed liquid passes through the evaporator to exchange heat with the external air, absorbs heat during vaporization, achieving the effect of refrigeration. Evaporators mainly consist of two parts: the heating chamber and the evaporation chamber. The heating chamber provides the necessary heat for evaporation, causing the liquid to boil and vaporize; the evaporation chamber ensures complete separation of the gas and liquid phases.
