Method of manufacturing a heat exchanger from a formable laminate ( 1, 11, 105 ) of a metal layer and a heat-seal layer whereby the laminate is sealed under heat and pressure to itself or to another similar laminate to form a flow channel for a heat exchange medium. Preferably the heat exchanger includes a series of fins ( 3, 106, 107 ) formed on the laminate ( 1, 11, 105 ) to increase heat transfer and may also include a water retaining layer ( 204 ). |
