Description

Technical Field

[0001] The utility model relates to the technical field of evaporators, in particular to a gas-liquid separation type combined evaporator. Background Art

[0002] Evaporation is the physical process of converting liquid into gas. Generally speaking, an evaporator is an object that converts liquid substances into gas. There are a large number of evaporators in the industry, and the evaporator used in refrigeration systems is one of them. The evaporator is a very important component among the four major refrigeration components. The low-temperature condensed liquid passes through the evaporator to exchange heat with the outside air, vaporize and absorb heat to achieve the refrigeration effect. The evaporator is mainly composed of two parts: the heating chamber and the evaporation chamber. The heating chamber provides the liquid with the heat required for evaporation, causing the liquid to boil and vaporize; the evaporation chamber completely separates the gas and liquid phases.
