Abstract

A radiator cooling apparatus for an automotive internal combustion engine is provided. The apparatus comprises an air suction duct or air injection duct connected to a closed-type blower. The suction duct draws ambient air through the core of the radiator and cools the hot water in the core. The injection duct injects ambient air toward the core and cools the hot water in the core. On the active surface of the duct, a plurality of bellmouths or nozzles are formed. The existing fan is removed from the engine, whereby fan noise is eliminated.

Claims

1. A radiator cooling apparatus for an automobile engine, comprising:

a liquid cooled automobile engine;

a main radiator for cooling said automobile engine, having a core connected to said liquid cooled automobile engine by a first hose for delivery of hot liquid to said main radiator from said automobile engine and a second hose for return of liquid cooled by said main radiator to said automobile engine; and

an air flow duct for flowing air through said main radiator, said air flow duct comprising a hollow rectangular body defined by opposite rectangular surfaces, one of said surfaces having a plurality of air conduits extending outwardly therefrom parallel to each other toward said core of said main radiator, said one of said surfaces facing said core of said main radiator closely adjacent thereto, and a blower enclosed within an air passage tube connected to the interior of said hollow rectangular body for blowing air through said tube such that air flows through said plurality of air conduits and thus through said core of said main radiator, said hollow rectangular body being substantially the same size as said main radiator.

2. The apparatus of claim 1, wherein said air conduits are nozzles tapering outwardly from said one of said surfaces toward said core of said main radiator, and said blower blows air out of said nozzles toward said core.

3. The apparatus of claim 2, wherein said main radiator is between said hollow rectangular body and said automobile engine such that air blows through said main radiator toward said engine.

4. The apparatus of claim 2, wherein said hollow rectangular body is between said engine and said main radiator.

5. The apparatus of claim 1, wherein said air conduits are bellmouths widening outwardly from said one of said surfaces toward said core of said main radiator, and said blower sucks air into said bellmouths, thus sucking air through said core.

6. The apparatus of claim 5, wherein said main radiator is between said hollow rectangular body and said automobile engine.

7. The apparatus of claim 5, wherein said hollow rectangular body is between said engine and said main radiator.

8. The apparatus of claim 1, wherein said blower is driven by an electric motor located inside said air passage tube.

9. The apparatus of claim 1, wherein said air conduits are distributed over said one of said surfaces in a uniform pattern.
