The plate heat exchanger is a new type of high-efficiency heat exchanger formed by stacking a series of metal plates with a certain corrugated shape. A thin rectangular channel is formed between the various plates to exchange heat through the phe plate. Compared with the conventional shell-and-tube heat exchanger, the heat transfer coefficient is much higher under the same flow resistance and pump power consumption, and there is a tendency to replace the shell-and-tube heat exchanger within the applicable range.
Corrugated plate heat exchanger is the ideal equipment for liquid-liquid, liquid-gas heat exchange. It has the advantages of high heat exchange efficiency, small heat loss, compact and lightweight structure, small footprint, convenient installation and cleaning, wide application, and long service life. Under the same pressure loss condition, the heat transfer coefficient is 3-5 times higher than the tubular heat exchanger, covers an area of one-third of the tube heat exchanger, and the heat recovery rate can be as high as more than 90%. Plate heat exchanger is widely used in metallurgy, petroleum, chemical, food, pharmaceutical, shipbuilding, textile, papermaking and other industries. It is an excellent equipment for heating, cooling, heat recovery, rapid sterilization and other purposes.
