Abstract
An energy exchange wheel having a wrapping hub which surrounds, and is concentric with but spaced from a central hub; an axially perforate matrix of energy exchange material around the wrapping hub; and a rim around the matrix. The axial dimensions of the central hub and the matrix correspond to the wheel depth, the axial dimension of the wrapping hub is between one-quarter and one-half of the wheel depth, and the axial dimension of the rim is at least equal to the axial dimension of the wrapping hub but less than the wheel depth. Tilted bar-like spokes secured to the central and wrapping hubs and to the rim prevent axial movement of the matrix. Also, a method for fabricating such wheel which includes wrapping the matrix material around the wrapping hub and a second, temporary wrapping hub, removal of the second hub, cutting of tilted slots in the matrix, surrounding the slotted matrix with a rim, inserting the spokes in the tilted slots, and securing the spokes to the central hub, the retained wrapping hub and the rim.
