Abstract
A heat exchanger assembly (10) for transferring heat comprising a heat exchanger core (12) having adjacent hollow tubes (14), heat exchanger fins (16) interconnecting adjacent tubes (14), and a plastic header (18, 118) molded about each of the ends of the tubes (14). A cover (22, 122) at the top and bottom of the heat exchanger core (12) attaches to each of the headers (18, 118) about the ends of the tubes (14) to enclose the tank. The invention includes a method for making the heat exchanger assembly (10) by molding the plastic header (18, 118) about each of the ends of the hollow tubes (14).
