Abstract

L’invention concerne un échangeur de chaleur (50) pour véhicule automobile, comportant :- une première section d’échange thermique (1) configurée pour permettre un échange thermique entre un fluide réfrigérant et un flux d’air (F),comprenant un premier faisceau de tubes (3) formant un ensemble de canaux de circulation du fluide réfrigérant,- une deuxième section d’échange thermique (2) configurée pour permettre un échange thermique entre un liquide caloporteur et le flux d’air (F),comprenant un deuxième faisceau de tubes (4) formant un ensemble de canaux de circulation de liquide caloporteur,dans lequel les tubes (3) du premier faisceau de tubes ont une forme en U comportant une première branche (5) et une deuxième branche (7) reliées par une base (6),dans lequel la première branche (5) est disposée en amont de la deuxième branche (7) selon un sens d’écoulement du flux d’air (F), etdans lequel le deuxième faisceau de tubes (4) est disposé entre la première branche (5) et la deuxième branche (7) des tubes (3). Figure de l’abrégé : Figure 1The invention relates to a heat exchanger (50) for a motor vehicle, comprising: - a first heat exchange section (1) configured to allow heat exchange between a refrigerant fluid and an air flow (F), comprising a first bundle of tubes (3) forming a set of channels for circulating the refrigerant fluid, - a second heat exchange section (2) configured to allow heat exchange between a heat transfer fluid and the air flow (F), comprising a second bundle of tubes (4) forming a set of channels for circulating the heat transfer fluid, in which the tubes (3) of the first bundle of tubes have a U shape comprising a first branch (5) and a second branch (7) connected by a base (6), in which the first branch (5) is arranged upstream of the second branch (7) in a flow direction of the air flow (F), and in which the second bundle of tubes (4) is arranged between the first branch (5) and the second branch (7) of the tubes (3).
