Plate Heat Exchangers

Plate Heat Exchangers Manufacturers in India

Plate Heat Exchangers have become effective modern method of cooling or heating flowing liquids through the method of conduction. The application of the Plate Heat Exchangers is basically cooling the hotter liquid or heating the cooler liquid.

The heat transfer plates are thin sheets having corrugations and patterns which increase the surface area of the plate hereby increasing the efficiency of heat transfer through conduction. The liquid is prevented from flowing sideways by thick gaskets which seals the PHE and also directs the liquid to flow in the appropriate alternate channel. The plates are supported and aligned by the guide bars and tightened by bolts between stationary and pressure frame. The equipment can adjust the number of plates to meet the heat duty.

Flow of Fluid and Heat Exchange Mechanism

Heat Transfer plates L and R are of identical pattern. L when rotated 180 degrees become R and vice versa. The plates are arranged in LRLR or RLRL combination giving the PHE a honey comb pattern when looked from sideways.

The first plate – E plate is having all port holes covered with the gaskets as this plate is touching the stationary frame. This double seal gasket prevents the flow between the stationary frame and the first plate.

Plate Press Patterns

Herringbone pattern is adopted for the plate press because of its high heat transfer efficiency. Combining this plates together creates more contact points making it possible to obtain strong pressure resistance.

In this way, a complex channel is formed creating highly turbulent flows to obtain excellent heat transfer performance.
