Plate heat exchanger,known as a new efficient and compact heat exchanger type, is composed of a series of corrugated shape of the metal sheet stacked into a new type of efficient heat exchanger, according to the different requirements, divided into many specifications and models. The choice of plate heat exchanger depends on three important factors, involving plate, pressure drop, flow and flow channel related issues. In the process of product selection, the above factors should be taken into account.
Plate heat exchanger design selection, the pressure drop is also a certain requirement, so it should be checked. If the pressure drop exceeds the allowable pressure drop, it is necessary to re-calculate the design selection until the process requirements are met.
Plate heat exchanger is a new type of heat exchanger composed of a series of stacked metal sheets. The plates are installed in a frame with movable plates and fixed plates on the side and tightened by clamping bolts. There are corrugated grooves in the opposite direction of each adjacent plate, and the corrugated grooves support each other to form a contact point. When the medium flows, turbulence will be formed and higher heat transfer efficiency will be obtained. The function of the sealing gasket is to seal the flow passage.
