What is brazed heat exchanger?

The brazed plate heat exchanger is made of many stamped corrugated sheets at certain intervals, sealed around by gaskets, and overlapped with a frame and a compression screw. The four corner holes of the plate and the gasket form the separation of the fluid. At the same time, the cold and hot fluids are reasonably separated so that they flow in the flow channels on both sides of each plate, and heat exchange is carried out through the plates.

Brazed plate heat exchangers have been widely used in metallurgy, mining, petroleum, chemical industry, electric power, medicine, food, chemical fiber, papermaking, light textile, shipbuilding, heating and other departments, and can be used for heating, cooling, evaporation, condensation, sterilization and disinfection , waste heat recovery, etc.

Brazed plate heat exchanger design features

1. High efficiency and energy saving: its heat transfer coefficient is 3000~4500kcal/m2·°C·h, which is 3~5 times higher than that of shell and tube heat exchangers.

2. Compact structure: The plates of the plate heat exchanger are closely arranged. Compared with other types of heat exchangers, the plate heat exchanger occupies less floor space and space, and the plate heat exchanger with the same area for heat exchange is only the tube 1/5 of the shell heat exchanger.

3. Easy to clean and easy to assemble and disassemble: the plate heat exchanger is clamped by clamping bolts, so it is easy to disassemble and assemble, and it can be opened and cleaned at any time.

4. Long service life: The plate heat exchanger is pressed by stainless steel or titanium alloy plates, which can resist various corrosive media.

5. Strong adaptability: The plate heat exchanger plate is an independent component, and the process can be increased or decreased at will according to the requirements, and the forms are various; it can be applied to various different process requirements.

6. No liquid leakage: The sealing groove of the plate heat exchanger is provided with a liquid leakage channel, and various media will not be connected with each other. Even if there is leakage, the medium will always be discharged outwards.
