- a heat exchanger allows the transfer of heat between two fluids through a heat exchange wall and without mixing the fluids.
- the heat exchange wall is generally made of the most conductive material possible, for example a metal such as copper, in order to promote heat exchange and limit thermal losses.
- Heat transfer is promoted by the temperature difference between the two fluids, with heat going from hotter to colder.
