Plate Heat Exchanger Types

As shown above right.

Plate heat exchanger types. Another type of heat exchanger is the plate heat exchanger. This facilitates the transfer of heat and greatly increases the speed of the temperature change. Figure 4 heat transfer in a double pipe heat exchanger. Baffles direct the flow of fluid between plates.

Each pair of plates creates a channel through which one fluid can flow and the pairs are stacked and attached via bolting. Advances in gasket and brazing technology have made the plate type heat exchanger increasingly practical. These exchangers are composed of many thin slightly separated plates that have very large surface areas and small fluid flow passages for heat transfer. A plate heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two fluids this has a major advantage over a conventional heat exchanger in that the fluids are exposed to a much larger surface area because the fluids are spread out over the plates.

Plate type heat exchanger consists of plates instead of tubes to separate the hot and cold fluids. There are two inputs and two outputs and the spaces between plates alternate between the two liquids hot cold hot cold etc. Also referred to as plate type heat exchangers plate heat exchangers are constructed of several thin corrugated plates bundled together. A third type of heat exchanger is a plate and shell heat exchanger which combines plate heat exchanger with shell and tube heat exchanger technologies.

Because each of the plates has a very large surface area the plates provide each of the fluids with an extremely large heat transfer area. Plate and shell heat exchanger.
