## Abstract

A vortex gas cooler having a compound fan which directly generates two gas stream vortex flows required for cooler operation.

## Claims

### Claim 1

A vortex gas cooler having:
(a) a cylindrical tube;
(b) a fan within said tube, said fan having outer region, rotatable fan blades disposed to impel an outer region vortex gas flow having circular motion and also moving through said tube in a first linear direction, said fan having an inner region which permits passage of an inner vortex gas flow within said outer vortex gas flow, said fan disposed to directly generate a gas vortex flow pattern within said tube.

### Claim 2 (depends on 1)

The vortex gas cooler of claim 1 wherein said fan inner region has rotatable fan blades disposed to impel said inner region vortex gas flow.

### Claim 3 (depends on 2)

The vortex gas cooler of claim 2 wherein said inner and outer region fan blades are disposed to impel vortex gas flow streams which have linear flow of opposite directions within said tube.

### Claim 4 (depends on 1)

The vortex gas cooler of claim 1 wherein said fan has a central shaft extending along the axis of said tube, and an electrostatic potential is applied between said shaft and said tube.

### Claim 5 (depends on 1, 2)

The vortex gas cooler of claim 1 or 2, wherein said tube has a circular cross section, and said tube is formed into a circle such that said tube has a torus geometry.
