Allen, R R

Space heating is disclosed which uses solar radiation as a thermal energy source to passively heat spaces within a structure which are substantially remote from direct solar radiation. A device according to the invention includes a radiation target, a closed and sealed circuit path for a fluid, such as a liquid, which is employed to communicate thermal energy from a radiation source to a thermal dissipation sink and a thermal dissipator, all incorporated as elements of a wall module which is adapted to be placed centrally within a structure which may not have a south -facing outer wall. A clerestory generally above the wall module provides a window for solar radiation to the radiation target. The fluid is conveyed by a thermal siphon effect, that is, by fluid convection, in a closed and sealed circuit. A vertical differential is provided within the closed circuit, and a thermal differential between segments of the circuit develops sufficient power to effect fluid circulation.
