A cooling system is provided with a heat exchanger that has a thermally conductive
tube over-molded with a plurality of thermally conductive fins. To form the heat
exchanger, a thermally conductive tube is provided. Insert molding, over molding
or injection molding is utilized to incorporate thermally conductive fins with
the thermally conductive tubes. The molding process may also simultaneously create
any required features, such as mounting features and fittings for tubing to be
connected to the heat exchanger.
