Plate Heat Exchangers :
 

A plate heat exchanger is a type of heat exchanger that uses metal plates to transfer heat between two liquids. This has a major advantage over a conventional heat exchanger in that the liquids are exposed to a much larger surface area because the liquids spread out over the plate. This facilitates the transfer of heat, and greatly increases the speed of the temperature change. It is not as common to see plate heat exchangers due to the fact that they need well-sealed gaskets to prevent the liquids from escaping, although modern manufacturing processes have made them feasible.
