The condenser is the other heat exchanger in a mobile A/C system. Nowadays, condensers are usually made of aluminum, but in the past, some were made of copper/brass. Condensers look very much like radiators, just a little thinner, and since they also depend on air flowing through them, are usually located in front of the radiator.
