A heat exchanger (Fig. 1) has nests (11, 11) of straight, flat tubes (21) with their broad sides adjacent and spaced apart to provide intermediate spaces. One medium, for example oil, flows through the tubes, and another medium, for example cooling air, flows in the intermediate spaces across the tubes. To provide a curved path (for instance an annular path) of flow of the one medium, yet using the straight, flat tubes, an angular connecting box (12) is used. Plates (23) with apertures (22) provide for connection of the nests of tubes to the angular connecting box. By the use of several such boxes and nests of tubes, an annular heat exchanger can be built up, with minimum waste of material during manufacture. <IMAGE> |
