Method of manufacturing a heat exchanger from a formable laminate (1, 11, 10 5) 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). |
