General heating and cooling duties.
Standard 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 interplate
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 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.
