The plate heat exchanger is a kind of heat exchanger that is made of thin metal plates pressed into heat exchange plates with a certain corrugated shape, then stacked, and assembled with frame plates and clamping bolts. The working fluid flows through the narrow and tortuous channels formed between the two plates, and the hot and cold fluids flow through the channel plates between the plates for cold and heat exchange.

Plate heat exchanger is an advanced heat exchange equipment with high efficiency, energy saving, material saving and investment saving. Nuclear industry, seawater desalination and cogeneration and other industrial fields can meet the requirements of various cooling, heating, condensation, concentration, disinfection and waste heat recovery processes, and have replaced traditional shell-and-tube heat exchangers in some industrial fields. With its development, the field of application will become wider and wider.

The plate heat exchanger is a kind of heat exchanger that is made of thin metal plates pressed into heat exchange plates with a certain corrugated shape, then stacked and fastened with splints and bolts. Thin rectangular channels are formed between the various plates, and heat exchange is performed through the half plates. The working fluid flows through the narrow and tortuous channel formed between the two plates. The hot and cold fluids pass through the flow channel in turn, and there is an interlayer plate in the middle to separate the fluids, and exchange heat through the plates.

The plate heat exchanger has high heat transfer coefficient, small footprint and light weight, and can realize heat exchange of various fluid media. The plates of the plate heat exchanger can be disassembled and washed, which is convenient for daily maintenance. It is made of stainless steel, which greatly improves the service life of the heat exchanger.
