Abstract

L’invention propose un circuit d’admission d’air de moteur thermique à injection indirecte de carburant dans au moins deux cylindres comprenant une culasse et un échangeur de chaleur (22) fixé à une face d’admission de la culasse pour refroidir l’air d’admission. L’échangeur de chaleur comporte :- une pluralité de rangées de conduits réfrigérants dans chacun desquels un liquide réfrigérant circule et qui, deux à deux, délimitent une cellule de circulation d’air d’admission,- une pluralité d’ailettes de refroidissement (38) transversales plissées agencées dans chaque cellule comportant des plis réguliers (42) continus formant des conduits transversaux dans lesquels l’air d’admission circule, et- une pluralité de persiennes (52) formées dans les plis réguliers d’au moins une ailette de refroidissement, et prévues pour améliorer les échanges thermiques entre des conduits transversaux adjacents,caractérisé en ce qu’au moins une ailette de refroidissement comporte au moins une portion (53) dépourvue de persiennes.
