Abstract

This invention relates to a compact heat exchanger-ventilation unit, for vehicles driven by internal-combustion engines which is compact and permits use of a narrow, low hood. The cooling air fan 1 has a diffuser and the resistance of the heat exchangers on the cooling air side is adapted to the delivery level of the cooling air fan 1. A refrigeration system condenser 7, charge air cooler 6, transmission oil cooler 4, motor coolant heat exchanger 3 and hydraulic oil cooler 5 are thus compactly arranged.
