How Plate And Frame Heat Exchanger Work

How Plate And Frame Heat Exchanger Work?

  The plate heat exchanger is composed of a plate heat exchanger plate, a balance tank, a centrifugal sanitary pump, a hot water device, a bracketHow Plate And Frame Heat Exchanger Work and a meter box. The plate heat exchanger is a heat exchanger made of a thin metal plate pressed into a heat exchanger plate with a certain corrugated shape, then stacked and fastened with splints and bolts. A thin rectangular channel is formed between the various sheets, and heat exchange is performed through the phe plates. The working fluid flows through the narrow, tortuous passage formed between the two plate heat exchanger 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 the plate heat exchanger determine its compact structure, small footprint, high heat transfer efficiency, large operational flexibility, wide application range, low heat loss, and convenient installation and cleaning.

  The structural principle of plate and frame heat exchanger is formed by a plurality of stamped corrugated sheets at regular intervals, surrounded by gaskets, and pressed by a frame and a compression screw. The four corner holes of the plate and the gasket are formed fluid distribution pipe and the collecting pipe are simultaneously separated from each other reasonably, so that they flow in the flow paths on both sides of each of the plates, and heat exchange is performed through the plates. The optimal design calculation of the plate heat exchanger is to determine the model, flow and heat transfer area reasonably under the condition of known temperature difference ratio NTUE, so that NTUp is equal to NTUE.
