Air cooling of vehicle radiators
First Claim
1. In combination with a vehicle hood and windshield, an engine compartment, an engine in the compartment, and a heat radiator located to pass cooling air flowing toward the engine, the radiator having an air inlet side, said combination comprisinga) a cooling air receiving plenum chamber located at the air inlet side of the radiator, andb) air inlet ducting having an entrance proximate the windshield to receive air flowing over the vehicle hood,c) and at least one passage communicating with said air inlet ducting and said plenum chamber to deliver cooling air to said plenum chamber for flow through the radiator.

Abstract
In combination with a vehicle hood and windshield, an engine compartment, an engine in the compartment, and a heat radiator located to pass cooling air flowing toward the engine, the radiator having an air inlet side, that combination comprising a cooling air receiving plenum chamber located at the air inlet side of the radiator; air inlet ducting having an entrance proximate the windshield to receive air flowing over the vehicle hood; and at least one passage communicating with the air inlet ducting and the plenum chamber to deliver cooling air to the plenum chamber for flow through the radiator. One plenum chamber acts to recover air pressure for efficient direct application to the radiator.

23. For combination with a vehicle hood and windshield, an engine compartment, an engine in the compartment, and a heat radiator located to pass cooling air flowing toward the engine, the radiator having an air inlet side, the combination comprising
a) a cooling air receiving plenum chamber located at the air inlet side of the radiator, and b) air inlet ducting having an entrance proximate the windshield to receive air flowing over said vehicle engine hood, c) and at least one passage communicating with said air inlet ducting and said plenum chamber to deliver cooling air to said plenum chamber for flow through the radiator, d) and wherein the plenum chamber has an effective flow cross sectional area A1, and the passage or passages flowing air to the plenum chamber has or have an effective cross-sectional flow area A2, where A1 is substantially greater than A2 for effecting recovery of air pressure in the plenum chamber to be applied directly to the radiator, and where the plenum chamber effectively spans the flow receiving side of the radiator.
