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.
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
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.
