<p>A heat exchanger, in particular for cars with exposed wheels, of fluid/air exchange type is constituted by a plurality of hollow elements (13) through which a high-temperature fluid flows and which are connected, at one of their sides, with a delivery duct (15), and at their other side, with a return duct (16), with said ducts being connected with a heat source. The hollow elements are provided with radiative surfaces (19,23,28,30) in the form of fins exposed to atmospheric air. The hollow elements through which the high-temperature fluid flows are flattened, superimposed to one another and/or arranged alongside one another and define, between them, passages (17) for a stream of flowing air which laps the radiative surface, which is individuated inside said passages and has a prevailingly longitudinal development, with said hollow elements being essentially parallel to one another and arranged spaced at a distance which corresponds to approximately 1/10 of their length. <IMAGE></p> |
