Plate heat exchanger consists of a set of corrugated metal plates, plate with a hole for the heat transfer fluid through The two metal plates mounted on a side pressed by the fixed plate and activities within the framework of the board, and with clamping bolt clamping. Plate is equipped with a gasket, sealing the fluid channel and guide the fluid to flow alternately to each channel. Fluid to flow, physical properties, pressure drop and temperature difference determines the existence of discrete plate number and size. Corrugated board not only improve the flow degrees, and the formation of a number of support points, enough to withstand the pressure difference between the media.
