[0002] A plate heat exchanger is a highly efficient, compact heat exchange device used for heat transfer between liquids, liquids, and vapors. It consists of a series of thin metal plates with a specific corrugation pattern, typically made of corrosion-resistant materials such as stainless steel, titanium, and nickel. These plates are stacked on top of each other with gaskets and bolted together to form multiple, isolated flow channels.

The disassembly process of some heat exchangers is relatively complicated, and the heat exchange fins cannot be added or reduced according to usage requirements, which makes the heat exchanger unsuitable for various working environments.
