The theory behind heat transfer - Alfa Laval

A heat exchanger follows this principle in its endeavour to reach equalisation. With a plate type heat exchanger, the heat penetrates the surface, which separates the hot medium from the cold one very easily. It is therefore possible to heat or cool fluids or gases which have minimal energy levels. The theory of heat transfer from one
