A plate heat exchanger is a type of heat transfer device that is commonly used in a variety of industrial and commercial applications to exchange heat between two fluids. This type of heat exchanger consists of a series of plates that are stacked together with a small gap between them. The fluids to be heated or cooled flow through alternate channels formed between adjacent plates, allowing heat to transfer between the two fluids.
Plate heat exchangers are typically made from materials such as stainless steel, titanium, or nickel, depending on the application and the properties of the fluids being processed. They are commonly used in HVAC systems, refrigeration systems, and process heating and cooling applications, due to their high efficiency and compact size.
