Heat exchanger approach temperature indicates the effectiveness of a utility for its intended purpose. Heat transfer rate (Q) across a heat exchanger is governed by the following equation. Q = U×A×T. where, U is the heat transfer coefficient, A is the heat transfer surface area, T is the temperature difference between hot and cold fluids.
PLATE AND FRAME HEAT EXCHANGERSUnder such pressure conditions only a portion of the length of a plate heat exchanger plate would be used and a substantial surface area would be wasted. However, when less restrictive pressure drops are available the plate heat exchanger becomes an excellent condenser, since very high heat transfer coefficients are obtained and the condensation can be carried out in a single pass across the plate.
Plate heat exchangers are not suitable for high pressure applications because the gaskets would be expelled by the system pressure; this situation is referred to as gasket blow-out. However, it is possible to get around this problem by using a gasket-less design ; these designs usually use brazed or welded plates .
Pressure Drop in Plate Heat Exchangers for Single-Phase Plate heat exchangers (PHE) are widely used in industry. A compact size due to high heat transfer coefficients is one major advantage over other heat exchanger types like shell and tube type. The special design of the flow channels results in early transition from laminar to turbulent flow and significant increase in heat transfer coefficients.

Alfa Laval - How plate heat exchanger workWith a plate heat exchanger, heat cuts through the surface and separates the hot medium from the cold. Thus, heating and cooling fluids and gases use minimal energy levels. The theory of heat transfer between mediums and fluids happens when:Heat is always transferred from a hot medium to a cold medium. There must always be a temperature
