Abstract

A heat exchanger, in particular a radiator for a cooling system of a motor-vehicle engine, comprises a plurality of tubes (8). The plurality of all the tubes (8) is defined by a single body in one piece, made by additive manufacturing technology. The tubes (8) each extend along a tortuous path, so as to increase the surface for heat exchange, without requiring the provision of auxiliary fins within the spaces between the tubes. The above-mentioned tubes (8) may have a sinusoidal configuration and may be aligned in rows and columns, according to a matrix arrangement, or they can define a three-dimensional net arrangement, with the tubes which communicate, or do not communicate, with each other, or they can define a tangled chaotic arrangement, with the tubes being in communication, or not in communication, with each other. The body of the heat exchanger may have a non-conventional configuration, such as an elongated and curved shape, so that it can be adapted to the shape of the front wall of a motor-vehicle, adjacent to which the heat exchanger is to be mounted.
