The structure of the plate heat exchanger is relatively simple. It consists of plates, gaskets, fixed compression plates, movable compression plates, compression studs and nuts, upper and lower guides and front pillars.The plate is the core component of the plate heat exchanger, and the heat transfer of both cold and hot fluids occurs on the plate. So it is a heat transfer element, and it also withstands the pressure difference on both sides.The plate is divided into horizontal straight corrugations, herringbone corrugations and oblique corrugations according to the corrugated geometry. The gasket is another key component of the plate heat exchanger.The working temperature of the plate heat exchanger is essentially the temperature that the gasket can withstand, and the working pressure of the plate heat exchanger is also considerably restricted by the gasket.The plate is very thin and has poor rigidity. It can only be made of elastic material. The structure of the plate heat exchanger gasket is 6~8 times longer than the heat exchange area. It exceeds any other type of heat exchanger. .
