[0002] Plate heat exchanger is a kind of high-efficiency heat exchanger composed of a series of stacked metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. Plate heat exchanger is an ideal equipment for liquid-liquid and liquid-steam heat exchange. It has the characteristics of high heat exchange efficiency, small heat loss, compact and light structure, small footprint, wide application and long service life. Under the same pressure loss, its heat transfer coefficient is 3-5 times higher than that of tubular heat exchanger, and the footprint is one-third of that of tubular heat exchanger.
