Aerodynamic recirculation duct to pass atmosphere air into the radiator and charge air cooler

A recirculation duct to pass atmospheric temperature air into a cooling package of a vehicle, the cooling package having at least a radiator and a charger air cooler, the recirculation duct comprising:

• a lower duct extending upstream from the cooling package, the lower duct having a lower portion with a recirculation shield contacting the cooling package while extending across a face of the cooling package to inhibit air hotter than atmospheric temperature air from a downstream side of the cooling package from entering an intake duct of the cooling package;
• a first side plate having a first end connected to a first end of the lower duct and contacting the cooling package while extending along a first side of the cooling package to inhibit air hotter than atmospheric temperature air from the first side of the cooling package from entering the intake duct of the cooling package;
• a second side plate having a first end connected to a second end of the lower duct and contacting the cooling package while extending along a second side of the cooling package to inhibit air hotter than atmospheric temperature air from the second side of the cooling package from entering the intake duct of the cooling package;
• and
• a center shield connected to the first side plate at a second end of 20 the first side plate and connected to the second side plate at a second end of the second side plate and contacting the cooling package while extending along a top of the cooling package to inhibit air hotter than atmospheric temperature air from the top of the cooling package from entering the intake duct of the cooling package.
