Abstract:
Heat exchanger, especially for a motor-vehicle engine cooling installation, comprising a plurality of separately-formed tubes (20) produced from a substantially flexible material and intended to carry a heat-exchange fluid suitable for interacting with a flow of fluid (F) passing through the exchanger, and a fastening system for holding the tubes in substantially parallel rows (20A), and wherein the tubes (20) are shaped so as to extend along substantially sinusoidal lines, while sinusoids of at least two tubes (211, 212) in contact at contact areas, of at least two respective consecutive rows defining at least two columns, are substantially offset in phase with respect to one another, such that the two tubes are held in two contact areas (210) per sinusoid period, wherein said rows and columns define an array of said tubes.
