1. After the pressing plate of the cleaning convenience plate heat exchanger is removed, the plate bundle can be loosened, and the plates can be removed for mechanical cleaning.

Simply changing the heat exchange area or process combination requires only adding (or reducing) plates to reach the heat exchange area that needs to be added (or reduced).

3. The quotation is not high. On the premise of using the same information, the production cost must be lower than that of the shell and tube heat exchanger due to the less information required for the layout.

4. The plate thickness of the lightweight plate heat exchanger is only 0.6~0.8mm, and the heat exchange tube thickness of the shell and tube heat exchanger is 2.0~2.5mm; The shell of a shell and tube heat exchanger is much heavier than the layout of a plate heat exchanger. When completing the same heat exchange mission, plate heat exchangers require less heat exchange area than shell and tube heat exchangers.

5. Small footprint plate heat exchangers have a compact layout, with a heat exchange area per unit volume that is 2 to 5 times that of shell and tube heat exchangers. It is also not like shell and tube heat exchangers that require reserved maintenance space for extraction tubes. Therefore, when completing the same heat exchange mission, the floor area of plate heat exchangers is about 1/5 to 1/10 of that of shell and tube heat exchangers.

"The layout of the high heat transfer coefficient tube shell heat exchanger is excellent in terms of strength, but it is not ambitious in terms of heat transfer perspective. As the fluid moves in the shell side, there are bypasses between the baffle plate shell, the baffle plate heat exchange tube, and the tube shell.". The fluid passing through these bypasses does not fully participate in heat exchange. In plate heat exchangers, there is no bypass, and the waviness of the plates can cause turbulence of the fluid at a small flow rate. Therefore, plate heat exchangers have a high heat transfer coefficient, usually 3-5 times that of shell and tube heat exchangers.
