Copper in heat exchangers

Copper is a common material used in Heat Exchangers because it conducts heat very well. This means it is able to absorb the heat it touches and spread it out to the other parts of the Heat Exchanger. Heat Exchangers are like giant radiators, they help transfer heat from one part of a machine to another part so that the machine doesn't overheat. Copper has a very high thermal conductivity which makes it especially good at absorbing and transferring heat so that the machine can keep running without getting too hot.
