Abstract

A low-cost but efficient collector of incident solar flux consists of a cover plate for transferring incident solar flux to a flat energy absorption member. The absorption member has a raised temperature which heats air on both sides. As a result, the air rises and passes finned tube 1. At the upper portion of the chamber, the air is cooled and then descends past finned tubes 2, 3, and 4 to the bottom of the chamber. Resultant cool air is then reheated by the absorption member and the cycle repeats.

Solar Energy Collection

A low-cost but efficient collector of incident solar flux consists of a cover plate for transferring incident solar flux to a flat energy absorption member. The absorption member has a raised temperature which heats air on both sides. As a result, the air rises and passes finned tube 1. At the upper portion of the chamber, the air is cooled and then descends past finned tubes 2, 3, and 4 to the bottom of the chamber. Resultant cool air is then reheated by the absorption member and the cycle repeats.

Water or other heat-exchanging fluid is pumped through the tubes beginning with tube 4, then 3, then 2, and finally the hottest tube 1. The chamber is suitably insulated on the side and rear portions. Tubes can be canted to allow for self- draining.

The above-described configuration provides a short thermal time constant at relatively reasonable cost.
