Working principle of plate and shell heat exchanger

The plate and shell heat exchanger is composed of a plate bundle and a shell. The plate set is welded by argon arc welding or plasma welding.

Plate and shell heat exchangers have high heat exchange efficiency, small terminal temperature difference, high temperature resistance, high pressure resistance, good sealing performance, low pressure drop, small footprint, safety and reliability, and compact structure. They have both plate heat exchangers and shell and tube heat exchangers. The advantage of the heat exchanger is that it is a new type of high-efficiency heat exchanger.

The fluid medium of the plate and shell heat exchanger flows in a pure countercurrent manner inside the plate and shell heat exchanger, which can produce highly turbulent flow and has an end temperature difference that cannot be achieved by other types of heat exchangers; the plate bundle has no flow channel holes and is all made of To exchange heat, the overall heat exchange efficiency is high; the diameter of the inlet and outlet pipes is flexible, making the plate and shell heat exchanger highly adaptable. The cover can be opened to allow mechanical cleaning of the flow channel. The shear stress generated by the fluid in the plate and shell heat exchanger in the flow channel is higher than that of other types of Welded Heat Exchangers, and it is not easy to scale. In addition, its unique flow channel design can also be used as a high-efficiency condenser.

The application scope of plate and shell heat exchangers includes but is not limited to petrochemical, pharmaceutical, food, beverage, beer, metallurgy, electric power, environmental protection, oil cooler and other industrial fields.
