How does plate and frame heat exchanger work

    Plate heat exchanger is a new type of high efficiency heat exchanger which is composed of a series of corrugated metal sheets.A thin rectangular2 channel is formed between various plates,and heat exchange is performed through the phe plates .Plate heat exchanger is the ideal equipment for liquid - liquid, liquid - steam heat exchange.It is characterized by high heat exchange efficiency, small heat loss, compact and light structure, small floor area, convenient equipment cleaning, wide application and long service life.Under the same pressure loss, the heat transfer coefficient is 3-5 times higher than that of the tubular heat exchanger, the floor area is one-third of that of the tubular heat exchanger, and the heat recovery rate can be as high as 90%.
