Plate Heat Exchanger

Plate heat exchanger is a highly efficient heat exchange system comprised of a series of metal sheets with a specific corrugated shape. These sheets are arranged to form thin rectangular channels that enable efficient heat exchange.

These industrial plate heat exchangers find extensive use across a wide range of industries such as chemical, petrochemical, electric power, nuclear power, light industry, food, medicine, machinery, heating and cooling, shipping, metallurgy, mining, driving power, and military. They meet the diverse technological requirements of these industries, including heating, cooling, evaporation, condensation, and waste heat recovery of process media.

PHE Plate Heat Exchanger Product Structure

Definition of PHE Plate Type Heat Exchanger: The plate heat exchanger is a highly efficient heat exchange system consisting of multiple metal sheets with specific corrugations. The arrangement of these sheets creates thin rectangular channels that facilitate effective heat exchange.

Types of Plate Style Heat Exchanger: There are primarily two types of plate heat exchangers - detachable plate heat exchangers and fully welded plate heat exchangers. Fully welded plate heat exchanger employs welded seals design, eliminating the pressure and temperature limitation of detachable plate heat exchangers with rubber gasket seals and improving equipment reliability.

There are three types of plates used in these heat exchangers - herringbone corrugated plates, horizontal straight corrugated plates, and nodular plates.

Composition of Plate and Fin Heat Exchanger: A plate-fin heat exchanger consists of three main components - fins, partitions, and seals. The fins are placed on one partition, then another partition is placed on top, and both sides are enclosed by seals to form a channel. These channels are stacked and arranged in various configurations and then brazed together to form the core-plate bundle unit of the plate-fin heat exchanger.

all welded plate heat exchanger belongs to dividing wall type heat exchanger. In terms of the heat transfer mechanism, its biggest feature is its extended secondary heat transfer surface, so the heat transfer process is not only carried out on the primary heat transfer surface but also on the secondary heat transfer surface simultaneously, and the secondary heat transfer area is larger, usually 1.5 - 3 times the primary heat transfer surface area. The fully welded heat exchanger has the secondary heat transfer area, which is incomparable to other heat exchange equipment.
