The plate heat exchanger plate is specially used for the plate heat exchanger to isolate the medium and exchange heat, and is an important part of the plate heat exchanger. Its main materials are stainless steel (SUS304.316), titanium and titanium palladium (Ti, Ti-Pd), 20Cr, 18Ni, 6Mo (254SMO), alloy (C276) and copper (H68.
The corrugated type of the plate heat exchanger plate mainly has two kinds of "herringbone" and "horizontal straight" corrugation. The pressure-bearing capacity of “herringbone” corrugated sheets is higher than 1.0Mpa, and the pressure capacity of “horizontal straight” corrugated sheets is generally 1.0Mpa. The heat transfer coefficient and fluid resistance of the "herringbone" corrugated sheet are higher than the corrugated pattern of the "horizontal straight" . Corrugated plate mainly considering the working pressure of the plate heat exchanger, the pressure drop of the fluid and the heat transfer coefficient. If the working pressure is above 1.6Mpa, the "herringbone" corrugated sheet should be selected. If the working pressure is not high and the resistance is required to be reduced, the "horizontal straight" corrugated sheet can be selected. Due to the limitation of installation space, the heat exchange efficiency is required to reduce the floor space of the plate heat exchanger, and the resistance drop is not limited. The "herringbone" corrugated plate should be selected.
