US 3,933,136 A · Cooling apparatus for passenger motor vehicle

Abstract

Cooling apparatus for cooling an engine on a motor vehicle including at least one heat exchanging cooler extending transversely of the motor vehicle and arranged below a storage compartment at one end of the vehicle. To enhance the flow of cooling air through the cooler, an air deflection member is provided adjacent the exit end of the coolers, which deflection member causes a vacuum suction at the exit end of the cooler in response to air flowing past the vehicle at high speed during driving of the vehicle. Adjacent the forward end of the air entrance to the coolers, an upwardly extending opening is provided between an endmost bumper and vehicle body parts forming a tire storage compartment, which upwardly extending opening also creates a vacuum suction effect at the entrance to the coolers in response to air flowing over the outside of the vehicle adjacent the bumper and a hood covering the storage compartment. In preferred embodiments, a pair of coolers are arranged which are inclined downwardly in the forward direction of the vehicle, with the most forward of the coolers being approximately one-half the vertical height of the most rearward of the coolers, and with the inlet air deflecting means being designed to direct a greater portion of inlet air to the lower half of the combination of coolers than to the upper half thereof. Another preferred embodiment with a single vertical cooler includes a blower at the rear of the cooler for enhancing the flow of air therethrough as well as a partition between the lower air deflector and the cooler.
