How Plate Heat Exchangers Work
The plate heat exchanger is a heat exchanger which is formed by pressing a thin metal plate into a plate having a certain corrugated shape, and then stacking and fastening with a frame and a bolt. A thin rectangular channel is formed between the various sheets, and heat exchange is performed through the half sheets. The working fluid flows through the narrow, tortuous passage formed between two plates. The hot and cold fluid passes through the flow passage in turn, and a partition plate in the middle separates the fluid and exchanges heat through the plate. The structure and heat exchange principle of phe determine its compact structure, small footprint, high heat transfer efficiency, large operational flexibility, wide application range, low heat loss, and convenient installation and cleaning.
