Description

Technical Field

[0002] The heat exchanger plate is the core component of the plate heat exchanger, which is specially used to isolate the medium and perform heat exchange. During the operation of the heat exchanger, the heat exchange of the plate with hot water is a crucial link. If we cannot use cleaning agents to clean the inside of the heat exchange tube during this process, a series of problems may occur.

[0003] Due to long-term lack of cleaning, a large amount of scale, sediment, corrosion products, polymers, fungi, algae, mud and other dirt may accumulate inside the heat exchange tube. These dirt will seriously affect the heat exchange efficiency of the heat exchanger, making it impossible for hot water to effectively transfer heat, resulting in energy waste. At the same time, due to the reduced heat exchange efficiency, the equipment may require more energy to maintain the same heat output, further increasing the operating cost. Therefore, there is an urgent need for a cleaning device that does not require disassembly of the heat exchanger plates to solve the above problems. Utility Model Content
