In
Heat exchanger system, the new
and latest type of compact and effective model Heat exchanger is plate
type heat exchanger. Another type of heat exchanger is the plate heat
exchanger. One is composed of multiple, thin, slightly-separated plates
that have very large surface areas and fluid flow passages for heat
transfer. This stacked-plate arrangement can be more effective, in a
given space, than the shell and tube heat exchanger.
Advances in gasket and brazing technology have made the plate-type heat exchanger
increasingly practical. In HVAC applications, large heat exchangers of
this type are called plate-and-frame; when used in open loops, these
heat exchangers are normally of the gasketed type to allow periodic
disassembly, cleaning, and inspection. There are many types of
permanently-bonded plate heat exchangers, such as dip-brazed and
vacuum-brazed plate varieties, and they are often specified for
closed-loop applications such as refrigeration. Plate heat exchangers
also differ in the types of plates that are used, and in the
configurations of those plates. The closely spaced metal heat transfer
plates have troughs or corrugations, which induce turbulence to the
liquids flowing as a thin stream between the plates.
The plates have corner ports, which in the complete plate pack form
a manifold for even fluid distribution to the individual plate
passages. As an exclusive feature, parallel flow heat exchanger plates
have interlocking gaskets in which upstanding lugs and scallops are
sited intermittently around the outside edges. The seal between the
plates is established by a peripheral gasket which also separates the
thru port and flow areas with a double barrier. The interspaces are
vented to atmosphere to prevent cross-contamination in the rare event
of leakage. Plate heat exchanger, consists of a stationary head and end
support connected by a top carrying bar and bottom guide rail. These
form a rigid frame, which supports the plates and moveable follower.
