Title
(EN) HEAT EXCHANGER WITH FLEXIBLE TUBES
(FR) ECHANGEUR DE CHALEUR A TUBES SOUPLES
Abstract
(EN)
The invention concerns 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.
(FR)
La présente invention concerne un échangeur de chaleur (2) à tubes (20) souples, en particulier pour une installation de refroidissement de moteur de véhicule automobile. Les tubes (20), par exemple réalisés en matière plastique, sont destinés à acheminer un fluide d'échange thermique propre à coopérer avec un flux d'air traversant l'échangeur (2). L'échangeur (2) selon l'invention comporte des moyens de maintien des tubes (20) en rangées parallèles. Les tubes (20) sont conformés pour présenter des formes générales de lignes sensiblement sinusoïdales. Les sinusoïdes de deux tubes (211, 212) en contact, de deux rangées consécutives, sont décalées en phase l'une par rapport à l'autre de sorte que les deux tubes (211, 212) sont maintenus en deux zones de contact (210) par période de sinusoïde, ce qui permet de laisser des interstices entre les tubes (20) pour favoriser la pénétration du flux.
