The plate positioning is determined by five points of metal-to-metal contact. Three points on the upper support rod prevent the plate from moving vertically, and the two points on the lower support rod prevent lateral movement.
The plate heat exchanger consists of a set of corrugated metal plates with four corner holes for the two heat-transferring liquids to pass through. The metal plates are mounted within a frame with fixed plates and movable clamping plates on one side and are clamped with bolts. Sealing gaskets on the plates seal the fluid passages and guide the fluids to flow alternately into their respective channels, forming heat exchange. The fluid flow rate, physical properties, pressure drop, and temperature difference determine the number and size of the plates. The corrugated plates not only increase turbulence but also create numerous support points sufficient to withstand the pressure difference between the media. The metal plates and movable clamping plates are suspended from the upper guide rod and positioned by the lower guide rod, while the rod ends are fixed to support columns.
