Plate Heat Exchanger

Working Principle
Channels are formed between the plates and the corner ports are arranged so that the two media flow through alternate channels.
The heat is transferred through the plate between the channels, and complete counter-current flow is created for highest possible
efficiency. The corrugation of the plates provides the passage between the plates, supports each plate against the adjacent one
and enhances the turbulence, resulting in efficient heat transfer.

Structural design
The plate heat exchanger consists of a pack of corrugated metal plates with portholes for the passage of the two fluids between which heat transfer will take place. The plate pack is assembled between a fix frame plate and a movable pressure plate and compressed by tightening bolts. The plates are fitted with a gasket which seals the interpolate channel and directs the fluids into alternate channels. The number of plates is determined by the flow rate, physical properties of the fluids, pressure drop and temperature program.
The plate corrugations promote fluid turbulence and support the plates against differential pressure. The frame plate and the pressure plate are suspended from an upper carrying bar and located by a lower guiding bar, both of which are fixed to a support column. Connections are located in the frame plate or, if either or both fluids make more than a single pass within the unit, in the frame and pressure plates.
