Abstract

A heat transfer device includes first and second members mounted for continuous relative rotation in either of a clockwise or a counterclockwise direction while maintaining substantially equally sized gaps between a plurality of equally spaced concentric fins which are alternately disposed in overlapping relationship.

Claims

1. A heat transfer device comprising:

a first member adapted for connection to a heat source and having a plurality of equally spaced parallel faced fins;

a second member adapted for connection to a heat sink and having a plurality of equally spaced parallel faced fins alternately disposed in overlapping relationship with the first member fins to form substantially equally sized gaps therebetween;

the fins of the first and second members forming concentric hollow cylinders and being mounted for continuous relative rotation while maintaining the substantially equally sized gaps; and

means providing helium gas under pressure filling said gaps between said fins.
