Abstract

A cooling delivery system for a vehicle including a plurality of baffles mounted to the vehicle'"'"'s engine compartment hood. A hood having a plurality of screens is pivotally mounted on the hood to cover the baffles in a down position. An air intake duct has a portion extending through the hood beneath the cover for receiving and conducting ambient air to a blower fan whereafter the ambient air is forced by the blower fan to traverse the vehicle'"'"'s radiator.

Claims

1. A cooling air delivery system for a vehicle, said vehicle having an engine compartment enclosing an engine driving fan having radially spaced blades located opposite a radiator, and a shroud mounted between said radiator and said fan, comprising:

said compartment having a hood, at least a first and second baffle fixedly mounted to the external surface of said hood;

said baffles being in longitudinal spaced apart relationship, extending transversely across said hood and projecting upwardly therefrom;

a first generally rectangular shaped opening in said hood rearward of said baffles, and a second generally rectangular shaped opening in said hood forward of said baffles;

a cover pivotally mounted to said hood such that in a first position said cover encloses said baffles and said first and second openings in said hood and in a second position said baffles and said first and second openings are exposed;

said cover being in a vertically spaced apart relationship to said baffles and having a plurality of screened openings forming part of said cover and extending between the said projecting baffles for admitting air into said cover.

2. A cooling air delivery system as claimed in claim 1 further comprising:

an air intake duct having a first portion defining an entrance, said first portion extending matingly through said first opening, and a second portion defining an exit which extends circumferentially around the peripheral path of said fan blades;

an engine respirator duct having a portion defining an entrance extending through said second opening in said hood and encapsulating an air filter, an exit duct extending into said respirator duct from said engine;

means for fixably supporting said air intake duct and said respirator duct in said engine compartment.
