Abstract
A heat exchanger (2) with flexible tubes (20), particularly for a motor vehicle cooling installation. The tubes (20), for example made of a plastic material, are designed to carry a heat-exchanging fluid capable of co-operating with an air stream circulating through the exchanger (2). The inventive exchanger (2) comprises means for maintaining the tubes (20) in parallel rows. The tubes (20) are designed to be generally shaped like substantially sinusoidal lines. The sinusoids of two contacting tubes (211, 212) of two consecutive rows, are phase offset relatively to each other such that the two tubes (211, 212) are maintained in two contact zones (210) per sinusoid interval, thereby leaving interstices between the tubes (20) to enhance the penetration of the flux.
Claims11
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.
