Description

Technical Field

[0001] The utility model relates to the technical field of surface coolers, in particular to a corrosion-resistant surface cooler. Background Art

[0002] The full name of surface cooler is surface cooler, which is a device used to heat or cool the air. Its working principle is to allow the heat medium, coolant or refrigerant to flow through the inner cavity of the metal pipe, and at the same time allow the air to be treated to flow through the outer wall of the metal pipe, so as to achieve the purpose of heating or cooling the air through heat exchange.

[0003] In actual production, in order to increase the service life of the surface cooler, it is usually made of corrosion-resistant materials such as stainless steel to improve the corrosion resistance and service life of the surface cooler. When using the surface cooler to cool the air, it is usually necessary to connect the refrigerant delivery pipe to the water inlet pipe and the water outlet pipe, and then inject the refrigerant liquid into the water inlet pipe through the delivery pipe, so that it flows into several metal pipe cavities inside the surface cooler body. At the same time, the air to be treated is passed through the filter on one side so that it flows through the outer wall of the metal pipe and then discharged from the filter on the other side. The purpose of cooling the air is achieved through heat exchange. The exchanged refrigerant liquid is discharged from the outlet pipe. The refrigerant liquid will generate a certain impact force when circulating. When the surface cooler body has been used for a long time, the connection between the inlet pipe and the outlet pipe and the two refrigerant delivery pipes may become loose, thereby causing the transported refrigerant liquid to overflow, affecting the use of the surface cooler and reducing the cooling effect.
