Description

Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to an anti-blocking device for heat exchangers. Background Art

[0002] A heat exchanger transfers heat to enable heat exchange between two or more fluids, thereby achieving the purposes of heating, cooling, or evaporation. It is widely used in industrial production, refrigeration, air conditioning, chemical engineering, petroleum, food processing, and other fields. Through efficient heat transfer, it improves energy utilization efficiency, reduces energy consumption, and ensures the stability of the process and the quality of products.

[0003] When the existing anti-blocking device for heat exchangers is in use, it cannot perform self-cleaning of the filter plate. On the one hand, as impurities accumulate, the permeability of the filter plate becomes worse, and the flow resistance of the fluid increases, resulting in a decrease in the heat exchange efficiency of the heat exchanger, thereby affecting the overall performance of the system. On the other hand, the filter plate cannot be cleaned in time, and the long-term accumulation of impurities will cause wear and damage to the filter plate and the heat exchanger itself, which may accelerate the aging and damage of the equipment and shorten the service life of the equipment.

[0004] In view of the above problems, we have introduced an anti-blocking device for heat exchangers. Summary of the Utility Model
