The frame and plate heat exchanger is a kind of plate exchanger made by pressing a thin metal plate into a certain ripple shape of the phe plate, paste on a sealing gasket,then stacking and fastening it with a clamping plate and bolts. The working medium flows through the narrow and tortuous channels formed between the two plates. The hot and cold fluid passes through the flow channels in turn, separating the media by sealing gaskets and spacer plates,and carry on heat exchange through the plates.
The structure and principle of the plate heat exchanger determine its compact structure, small footprint, high heat transfer efficiency, great operational flexibility, wide application range, and convenient installation and cleaning. The average temperature difference between the two media can be as small as 1℃ and the heat exchange efficiency can reach more than 99%. Therefore, the plate heat exchanger is an advanced equipment with highly efficient, energy-saving, material-saving, and cost-effective. It has been widely used in electric power, refrigeration, medicine, petrochemical, food, and other industrial fields.
