The corrugation on the plates forces the fluid on a tortuous path, setting a space between two adjacent plates b, from 1 to 5 millimeters. The most frequently used materials for the plates are stainless steel (AISI 304, 316), titanium and aluminium. Corrugation is achieved by cold forging of sheet metal with thicknesses of 0.3mm to 1 mm. Generally, these plates are corrugated in order to increase the turbulence, the thermal exchange surface and to provide mechanical rigidity to the exchanger. Fluids are divided into several parallel streams and can produce a perfect countercurrent. The figure shows the flow of fluids inside the exchanger. The number of plates in a single exchanger ranges from just ten to several hundred, so reaching surface exchange areas up to thousands of square meters. The size of a plate can range from a few square centimeters (100 mm x 300 mm side) up to 2 or 3 square meters (1000 mm x 2500 mm side). Inlet and outlet holes at the corners of the plates allow hot and cold fluids through alternating channels in the exchanger so that a plate is always in contact on one side with the hot fluid and the other with the cold. The space between two adjacent plates forms the channel in which the fluid flows.

Plate Heat Exchangers were first produced in the 1920s and have since been widely used in a great number of sectors.ДЄ plate exchanger consists of a series of parallel plates that are placed one above the other so as to allow the formation of a series of channels for fluids to flow between them.
