Solar collector
A solar collector is disclosed having a housing and a plurality of substantially parallel heat absorbing vanes mounted in the housing immediately beneath a radiation transparent upper wall in such a manner as to form a plurality of relatively narrow channels through which a heat exchange fluid is circulated. The width of the channels is preferably not greater than one-half of the depth of the channels and is preferably substantially less. The width of the channels may be as little as one-sixth of the depth of the channels. Provision is made for changing the angular disposition of the vanes and this may be done by heat sensitive means sensitive to the direction of the solar radiation. One form of the vane is L-shaped in cross section with a short leg of each L constituting the bottom wall of the channel and the long leg constituting a side wall of the channel. The vanes may be formed with ears projecting therefrom, these ears constituting the means for spacing the channels and also providing the means for pivotally mounting the channels. These ears may be disposed in channel-shaped members, one set of which is fixed to provide a pivotal support for the vanes and the other set of which is movable to facilitate shifting the angular position of the vanes. The ear may be formed from either a flat strip on which is secured a cylindrical sleeve or the ear may be formed from an extension of the vane which has been curved into a generally cylindrical form.
