The Plate heat exchanger consists of a pack of corrugated metal plates, The corrugation of the plates provides
the passage between the plates, the two fluids transfer the heat between the channels. The plate pack is
assembled between a fixed frame plate and a movable pressure plate and compressed by tightening bolts. The
gasket between the plates seals the interplate channel and directs the fluids into alternate channels.
The number of plates is determined by the design: the temperature program, flow rate, pressure drop and
physical properties of the fluids.
