ApplicationsGeneral heating and cooling duties.

Standard designThe plate heat exchanger consists of a pack of corrugatedmetal plates with port holes for the passage of the two fluidsbetween which heat transfer will take place.

The plate pack is assembled between a fixed frame plate anda movable pressure plate and compressed by tightening bolts.The plates are fitted with gaskets, which seal the interplatechannels and direct the fluid into alternate channels. Thenumber of plates is determined by the flow rate, physicalproperties of the fluids, pressure drop and temperatureprogram. The plate corrugations promote fluid turbulence andsupport the plates against differential pressure.

The frame plate and the pressure plate are suspended from anupper carrying bar and located by a lower guiding bar, bothof which are fixed to a support column.

Connections are located in the frame plate or, if either or bothfluids make more than a single pass within the unit, in theframe and pressure plate.

Working principleChannels are formed between the plates and the corner portsare arranged so that the two fluids flow through alternatechannels. The heat is transferred through the plate betweenthe channels, and complete counter-current flow is createdfor highest possible efficiency. The corrugation of the platesprovides the passage between the plates, supports eachplate against the adjacent one and enhances the turbulence,resulting in efficient heat transfer.
