Standard
Design and Working Principles
The
plate heat exchanger consist of a set of corrugated metal plates
which is available in different material (stainless steel, titanium,
etc), assembled between two frame plates compressed by tightening
bolts, guided by a upper carrying bar and a lower guide bar.
The plates are fitted
with gaskets at the outer edges and around the ports which are
so arranged that the two fluids are directed into alternately
into the passages formed between plates where the heat transfer
will take place through the thin plates and counter current flow
is created for highest efficiency. 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.
No intermixing of the
media or leakage to the surroundings will take place as gaskets
around the edges of the plates seal the unit. The corrugation
of the plates provides a suitable passage between the plates,
support of each plate against the adjacent one and a strong turbulence
resulting in maximum heat transfer efficiency.
