Vehicle parallel cooling system
First Claim
1. A cooling system for a vehicle having an engine, the cooling system comprising:
- a first heat exchanger for cooling a first subsystem of the vehicle;
a second heat exchanger for cooling a second subsystem of the vehicle, said first and second heat exchangers being laterally spaced apart in front of a front end of the engine;
a first air moving unit for blowing air through the first heat exchanger;
a second air moving unit for blowing air through the second heat exchanger, the second air moving unit being spaced laterally apart from the first air moving unit;
a duct having a first forward opening inlet receiving warmed air from the first heat exchanger, a second forward opening inlet receiving warmed air from the second heat exchanger, a first housing extending from the first inlet to a first upwardly opening outlet, and a second housing extending from the second inlet to a second upwardly opening outlet, each outlet being located rearwardly of the corresponding inlet and above the engine.

Abstract
A cooling system is provided for a vehicle having an engine. The cooling system includes a pair of heat exchangers, such as an oil cooler and a charge air cooler, laterally spaced apart from each other and located in front of a front end of the engine. A pair of blower units are in front of the coolers and blow cooling air rearwardly therethrough. A pair of duct units are located above the engine and to the rear of the coolers. Each duct unit includes a forward opening inlet receiving warmed air from the corresponding cooler, an upwardly opening outlet and a hollow housing extending from the inlet to the outlet. The outlets are spaced laterally apart from each other. A radiator is positioned above the duct unit housings and forward of the outlets. A set of radiator fans blow air upwardly through the radiator and are positioned between the radiator and the duct housings.
