Abstract (en)

The heat exchanger has two circuits (C1, C2) formed by inner (14) and outer (16) U-shaped channels, and feed and return pipes (50, 52) linked to the channels to deliver identical or different fluids (F1). The channels are bounded by facing pairs of plates (12) and are connected through apertures (28, 32); in a variant they are formed by U-shaped tubes.

Abstract (fr)

Un échangeur de chaleur, notamment de véhicule automobile, comprend des premiers canaux (14) en U définissant un premier circuit de fluide (C1), des seconds canaux (16) en U entourant les premiers canaux et définissant un second circuit de fluide (C2), des moyens d'alimentation (54 à 68) reliés aux premiers canaux (14) et aux seconds canaux (16) pour alimenter sélectivement le premier circuit (C1) et le second circuit (C2) par des fluides respectifs (F1 ; F2) qui peuvent être identiques ou différents. Dans une application préférentielle, les circuits (C1 et C2) sont propres à être parcourus par un fluide réfrigérant en fonctionnant comme un évaporateur, et le premier circuit (C1) est propre à être parcouru à lui seul par un fluide réfrigérant en fonctionnant comme un condenseur. <IMAGE>
