L'invention concerne un échangeur de chaleur, notamment pour
un équipement de véhicule automobile, comprenant une
pluralité de tubes (1) destinés à acheminer un fluide d'échange
thermique et réalisés dans un matériau souple, ainsi que deux
plaques collectrices (2a,2b) parallèles et comprenant des
ouvertures (3a,3b) pour loger respectivement les extrémités
de chaque tube (1). Ces ouvertures (3a,3b) sont agencées en
rangées parallèles pour former un faisceau de rangées de
tubes parallèles. Selon l'invention, les rangées successives
de l'une des plaques (2a) sont alternativement décalées vers
une première direction, parallèle aux rangées, puis vers une
seconde direction opposée à cette première direction, et les
rangées de l'autre plaque (2b) sont respectivement décalées
vers la seconde direction, puis vers la première direction,
de sorte que les tubes de deux rangées consécutives se
croisent entre les deux plaques collectrices (2a,2b). De
plus, deux rangées successives d'une même plaque (2a) sont
espacées d'un interstice (d) voisin d'une épaisseur de tube,
de sorte que les tubes de deux rangées consécutives, en se
croisant, sont en contact (C).
