A panel heat exchanger formed from two sheets of thermoplastic polymer is disclosed. Each sheet has a thickness of 0.07-0.7 mm and a plurality of grooves extending at least partially across the width of the sheet. Each sheet has a recess located at at least one end. The sheets are superimposed in face to face relationship and bonded together in a fluid tight bond such that (i) the recesses form portions of inlet and outlet header means at opposite ends of the panel, and (ii) the grooves form a plurality of fluid-flow channels between the inlet and outlet header means. The end of each groove of one sheet of the panel heat exchanger overlays the end of a groove of the other sheet. The panel heat exchangers are readily fabricated by simple means, preferably from polyamide compositions. The heat exchangers may be used in a variety of end-uses, including automotive oil coolers, automotive comfort heaters, refrigerators and industrial uses.
