technical field

The utility model relates to the technical field of heat exchangers, in particular to a heat exchanger with a heat dissipation structure.

Background technique

A heat exchanger is a device that transfers part of the heat of a hot fluid to a cold fluid. In the chemical industry, heat exchangers can be used as heaters, coolers, condensers, evaporators, reboilers, etc., and are widely used, such as low temperature in power plants. The PTFE heat exchanger is a new type of equipment for waste heat recovery in power plants to reduce the exhaust gas temperature. The fluoroplastic heat exchanger is used to prevent acid corrosion and reduce the flue gas temperature to 100 degrees.

Existing heat exchangers generally use cold and hot water for heat exchange for heat exchange. When cold water is exchanged with hot water, the front end can be exchanged normally, and the cold water at the rear has absorbed heat and continues to exchange heat with cold water. The heat exchange efficiency is greatly reduced, the heat exchange effect of the heat exchanger will be greatly reduced, and some heat exchangers do not have a filter device. After long-term use, some dirt sticks to the inner wall of the pipe, and the heat transfer efficiency is greatly weakened. Heat is not efficiently transferred to the outside of the aisle.
