Heat Exchangers
A heat exchanger is a device for transferring thermal energy from one fluid to another without mixing them. The heat flow passes through the exchange surface which separates the fluids.
The interest of the device lies in the separation of the two circuits and in the absence of other exchanges than heat, which maintains the physico-chemical characteristics (pressure, concentration of chemical elements…) of each fluid unchanged except for their temperature or their state.
A heat exchanger is characterized by the fluids present, the purpose and the power to be used; these criteria determine its shape and optimal dimensions.
