Abstract
A tube-within-a-tube, counter flow, air-to-air heat exchanger utilizing a rigid outer tube and a continuous, flexible inner tube. The corrugated, flexible inner tube is spiralled longitudinally around a center core and creates turbulence in the air which permits a rapid exchange of heat between the exhaust and fresh air streams.
