Abstract (en)

[origin: EP0097905A2] A heat exchanger consists of concentric sleeves (M1, M2), each formed by three helical turns of a tube (T1) equipped with two vertical and longitudinal fins (A1, B1), and made from a plastic containing a thermally conductive filler, this sleeve being formed by extruding the tube with its fins, and then bending. <IMAGE>
