A Plate Heat Exchanger (PHE) is a compact type of heat exchanger that uses a series of thin, corrugated metal plates to transfer heat between two fluids. These plates are stacked together, creating alternating channels for the hot and cold fluids to flow through. The close proximity and large surface area of the plates allow for highly efficient heat transfer.
They are extremely common in a wide range of industries, from HVAC and power plants to food and beverage processing and marine applications.
