Plate heat exchanger - Wikipedia


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. This facilitates the transfer of heat, and greatly increases the speed of the temperature change.

Heat balance. An application of the first law of thermodynamics to a process in which any work terms are negligible. For a closed system, one that always consists of the same material, the first law is Q + W = ΔE, where Q is the heat supplied to the system, W is the work done on the system, and ΔE is the increase in energy of the material forming the system.
