[0002] Plate heat exchangers are a type of high-efficiency heat exchanger consisting of a series of corrugated metal plates stacked together. Their working principle involves separating hot and cold fluids through the metal plates, thus transferring heat. Due to their advantages such as high heat transfer efficiency, compact structure, and easy assembly and disassembly, plate heat exchangers are widely used in various industries including chemical, food, pharmaceutical, and HVAC.

[0003] In the prior art, such as the patent publication number CN117367204A, "A Plate Heat Exchanger Cleaning Device", it includes a main component, which includes a plate heat exchanger body, a cleaning device, and a filter housing. A cleaning pipe is installed between the plate heat exchanger body and the cleaning device to transport cleaning fluid. The cleaning device and the filter housing are connected by a pipe to filter impurities contained in the cleaning fluid. A filter assembly is disposed inside the main component. The filter assembly includes a filter element installed on the inner wall of the filter housing. A driving element is installed at the bottom of the filter element, and a lifting element is slidably connected to the outside of the driving element.

[0004] Existing plate heat exchanger cleaning devices suffer from homogeneous structural designs and limited functionality, making it difficult to perform flushing and cleaning operations on critical areas inside the gaps between the plates of the plate heat exchanger. As a result, dirt and impurities remain on the surface of the plates after cleaning, which not only directly reduces the cleaning effect, but also further leads to a decrease in the heat exchange efficiency and operational stability of the plate heat exchanger, seriously affecting its actual performance and service life.
