Plate heat exchangers incorporate metal plates to facilitate efficient heat transfer between the two fluids. They are better than the conventional heat exchangers because fluids get a larger surface area as they spread over the plates. The transfer of heat and speed of temperature change is swift. The plate heat exchangers are made up of many corrugated stainless-steel sheets. The sheets are separated with the help of polymer gaskets. They are secured into steel frames. They carry out the exchange of heat with the help of corrugated, thin metal sheets adjacent to each other and connecting them with the help of gaskets. The substance that is to be cooled or heated is carried out between alternating sheets that allow the heat to pass through the metal sheet.
