Plate heat exchanger

It is a high-efficiency heat exchanger composed of a series of metal sheets with a certain corrugated shape. Thin rectangular channels are formed between the plates, and heat is exchanged through the plates. As an ideal equipment for liquid-liquid and liquid-vapor heat exchange, it has the characteristics of high heat exchange efficiency, small heat loss, compact and lightweight structure, small footprint, wide application, long service life and so on. Under the same pressure loss, the heat transfer coefficient is 3-5 times higher than that of the tube heat exchanger, but the floor area is only one third of that of the tube heat exchanger, and the heat recovery rate can be as high as more than 90%. There are two types of plate heat exchangers: frame (removable) and brazed. The plate types are mainly herringbone corrugated plates, horizontal straight corrugated plates and knob-shaped plates. They are widely used in metallurgy, Mining, petroleum, chemical, power, food, chemical fiber, papermaking, textile, marine, heating and other departments can be used for various situations such as heating, cooling, evaporation, condensation, sterilization, waste heat recovery, etc., and it is widely used.
