Abstract

A method and hybrid radiator-cooling apparatus for implementing enhanced radiator-cooling are provided. The hybrid radiator-cooling apparatus includes an air-side finned surface for air cooling; an elongated vertically extending surface extending outwardly from the air-side finned surface on a downstream air-side of the hybrid radiator; and a water supply for selectively providing evaporative cooling with water flow by gravity on the elongated vertically extending surface.

First claim

What is claimed is:

1. A hybrid radiator-cooling apparatus for implementing enhanced radiator-cooling comprising:
an air-side finned surface for air cooling;
an elongated vertically extending surface extending outwardly from said air-side finned surface on a downstream air-side of the hybrid radiator; and
a water supply for selectively providing evaporative cooling with water flow by gravity on said elongated vertically extending surface.

2. The hybrid radiator-cooling apparatus as recited in claim 1 includes a plurality of generally rectangular tubes defining a plurality of said elongated vertically extending surfaces extending outwardly from the air-side finned surface.

3. The hybrid radiator-cooling apparatus as recited in claim 1 wherein said water supply providing water droplets falling by gravity on said elongated vertically extending surface for evaporative cooling.

4. The hybrid radiator-cooling apparatus as recited in claim 1 wherein said water supply for selectively providing evaporative cooling with water flow by gravity on said elongated vertically extending surface responsive to a predefined thermal design condition for the radiator-cooling system.

5. The hybrid radiator-cooling apparatus as recited in claim 1 wherein said air-side finned surface for air cooling having a predefined size for air cooling to remove required engine heat under general driving conditions.

6. The hybrid radiator-cooling apparatus as recited in claim 1 wherein water supply for selectively providing evaporative cooling with water flow by gravity on said elongated vertically extending surface responsive to a predefined high heat load on an engine.

7. The hybrid radiator-cooling apparatus as recited in claim 1 includes a plurality of generally flat rectangular tubes for defining a plurality of said elongated vertically extending surfaces extending outwardly from the air-side finned surface having a selected area for evaporative cooling.

8. The hybrid radiator-cooling apparatus as recited in claim 7 wherein said water supply for selectively providing evaporative cooling with water flow by gravity on said elongated vertically extending surface includes said water supply providing water droplets falling by gravity on said elongated vertically extending surfaces for evaporative cooling.
