3.4 Function
The plate heat exchanger consists of a pack of corrugated metal plates with
portholes for the input and output of the two separate fluids. The heat transfer
between the two fluids takes place through the plates.
The plate pack is assembled between a frame plate and a pressure plate and
compressed by tightening bolts. The plates are fitted with a gasket which seals
the channel and directs the fluids into alternate channels. The plate
corrugation promotes fluid turbulence and supports the plates against
differential pressure.
