Description

Technical Field

[0001] The utility model relates to the technical field of evaporators, in particular to an evaporator used in refrigeration equipment. Background Art

[0002] An evaporator is a device that converts liquid into gas by heating. It is generally used to convert liquid into steam to achieve energy conversion and transfer. The evaporator used in refrigeration equipment is one of them. The evaporator is a very important component among the four major refrigeration parts. The low-temperature condensed liquid passes through the evaporator to exchange heat with the outside air, vaporizes and absorbs heat to achieve a refrigeration effect.

[0003] At present, the evaporator is mainly composed of two parts: a heating chamber and an evaporation chamber. The heating chamber provides the heat required for evaporation to the liquid, causing the liquid to boil and vaporize. At the same time, the evaporation chamber completely separates the gas and liquid phases. The inventors have found that in the process of introducing the refrigerant into the evaporator of the existing evaporator used for refrigeration equipment, the sealing effect of the connection between the refrigerant introduction pipe and the external pipe is not good. Therefore, we propose an evaporator for refrigeration equipment. Utility Model Content
