ABSTRACT:
The invention is a passive, stationary solar collector. The collector is a cylinder of essentially circular cross section set in a fixed position with its longitudinal axis laying essentially in a vertical north-south plane and at appropriate angle to the local horizontal plane of the earth. Liquid-carrying, heat-absorbing conduits run lengthwise on the external surface of said cylinder and convey heated liquid to the upper part of a reservoir internal to said cylinder. The conduits obtain cooler liquid from the lower part of said reservoir. Cooling of reservoir contents, during periods of low radiation, by relatively warmer liquid rising in the conduits from the lower part of said reservoir is prevented by a liquid density trap.
