A heat exchanger is a device for transferring thermal energy from one fluid or air to another without mixing them.

The heat flow passes through the exchange surface that separates the fluids.

The advantage of the device lies in the separation of the two circuits and in the absence of other exchanges than heat or cooling which keeps the physicochemical characteristics (pressure, concentration of chemical elements, etc.) of each fluid unchanged except for their temperature. or their condition.

An exchanger is characterized by the fluids present, the desired goal is the power to be used.

The exchangers can be:

– Air / water

– Air / Air

– Water / Water

– Oil / Air

– Oil / Oil

– Oil / Water …
