What is plate heat exchanger

   The structure of the plate heat exchanger is relatively simple. It consists of plates, gaskets, fixed compression plates, movable compression plates, compression studs and nuts, upper and lower guides, and front pillars. The pressing plate, the guide rod, the pressing device and the front pillar are collectively referred to as a frame of the plate heat exchanger. All the plates arranged in a certain regularity are called bundles. Its small parts and high versatility are unmatched by any heat exchanger. The plate heat exchanger is an ideal equipment for heat exchange between liquid-liquid and liquid-vapor. It has high heat exchange efficiency, small heat loss, compact and light structure, small floor space, convenient installation and cleaning, wide application and long service life. . In the case of the same pressure loss, the heat transfer coefficient is 3-5 times higher than the tube heat exchanger, and the floor space is one-third of the tube heat exchanger, and the heat recovery rate can be as high as 90% or more.
