Abstract

L'invention concerne un refroidisseur d'air de suralimentation pour un moteur à combustion interne, en particulier d'un véhicule automobile, comprenant un échangeur de chaleur (14) parcouru par de l'air de suralimentation et un réfrigérant dans des canaux séparés les uns des autres, un canal de dérivation (18) pour guider l'air de suralimentation sur l'échangeur de chaleur (14) et un module à clapets (12) intégré au refroidisseur d'air de suralimentation et comportant au moins un clapet de commutation dans la voie d'écoulement de l'air de suralimentation, pour guider de manière sélective l'air de suralimentation dans l'échangeur de chaleur (14) et/ou dans le canal de dérivation (18), une unité électronique (22) étant utilisée pour actionner ledit ou lesdits clapets de commutation. Dans ce cas, l'unité électronique (22) est disposée du côté du module à clapets (12) tourné vers l'échangeur de chaleur (14).
