Abstract
A heat wheel is made of spirally wound, interleaved, flat and corrugated strips of metal material. A plurality of circumferentially spaced pairs of radial rods extend between the wheel hub and the outer rim of the wheel. The rods of each pair are disposed in a radial plane and, in that plane, are at an angle to each other so as to form rigid triangular truss-type supports in angularly spaced axial planes.
