Title: Heat exchanger with flexible tubes, especially for a motor vehicle

Abstract: A heat exchanger for motor-vehicle equipment, has tubes (1) for a heat-exchange fluid and produced from a flexible material, as well as two parallel manifold plates (2a, 2b) with apertures (3a, 3b) for the extremities of each tube (1). These apertures (3a, 3b) are configured into parallel rows (rk, ri, rj) to form a bundle of rows of parallel tubes. The successive rows of one of the plates (2a) are offset alternately in a first direction, parallel to the rows, then in a second direction opposite to this first direction. The rows of the other plate (2b) are respectively offset in the second direction, then in the first direction, in such a way that the tubes of two consecutive rows cross over between the two manifold plates (2a, 2b). Moreover two successive rows of the same plate (2a) are spaced by an interstice (d) close to one tube thickness, in such a way that the tubes of two consecutive rows, in crossing over, are in contact (C).
