Plate heat exchangers basically consist of two inlet ports, ducted heat transfer plates and two outlet ports. Two of these inlet and outlet ports are the inlet and outlet of the heating fluid, and the other two are the inlets and outlets of the fluid to be heated. It is also possible to make heat exchangers with more than one heater or fluid to be heated with special production.
The function of the plates in the Plate Heat Exchanger is to provide heat transfer from the heating fluid to the fluid to be heated without mixing the fluids. The channeled structure of these plates allows the fluid to move in a highly turbulent manner. This turbulence causes a more homogeneous heat distribution of the fluid, which provides a more efficient heat transmission.
