The heat transfer plates of the plate heat exchangers are stamped


The plate heat exchanger has a compact structure, and the heat exchange area per unit volume is 2 to 5 times that of the shell-and-tube type. It is not necessary to reserve the inspection and repairing place of the tube bundle as in the shell-and-shell type, so the same heat exchange amount and plate exchange are realized. The heater covers an area of about 1/5 to 1/8 of the shell-and-tube heat exchanger.

Easy to change heat transfer area or process combination,

As long as a few plates are added or reduced, the purpose of increasing or decreasing the heat exchange area can be achieved; changing the plate arrangement or replacing a few plates can achieve the required process combination to adapt to the new heat exchange conditions, and the tube The heat transfer area of the shell heat exchanger is almost impossible to increase

Light weight

The thickness of the plate heat exchanger is only 0.4~0.8mm, while the thickness of the heat exchange tube of the shell-and-tube heat exchanger is 2.0~2.5mm. The shell-and-shell type is much heavier than the frame of the plate heat exchanger. Plate heat exchangers generally only have about 1/5 of the weight of the shell and tube.

Low price

Using the same material, the plate heat exchanger is about 40% to 60% lower than the shell-and-tube type under the same heat exchange area.

Easy to make

The heat transfer plates of the plate heat exchangers are stamped, highly standardized, and can be mass-produced. The shell-and-tube heat exchangers are generally hand-made.
