Abstract
Improved metallic heat exchange apparatus particularly useful in a wheel-like form as a sensible heat exchange wheel in an environmental control apparatus. The heat exchange apparatus is constructed of multiple layers of metallic 'honeycomb', with the apertures of the honeycomb layers axially parallel and offset with respect to each other. The multiple layers provide thermal discontinuities so that the face to face temperature gradient of the heat exchanger is continuous. The heat exchange apparatus of this invention is fireproof, a serious deficiency in prior art wax-coated sensible heat exchange wheels used in environmental control apparatus.
