SOLAR ENERGY COLLECTION SYSTEM AND FLUID CONDUIT THEREFOR

摘要

A solar energy collection system that can be retrofitted into pavement covered lots (10), such as macadam covered parking lots has a pump (52) and heat exchanger (54), and a conduit (12) buried below the pavement surface that contains a heat transfer fluid such as water. The conduit has a hollow unitary, one piece casing (70) with an oval cross section and an internal divider (72) that divides the interior of said casing into two passageways (74,76) having substantially the same cross sectional area. Heat conducting fins (84,86) preferably made of copper are mounted on the casing and exted coaxially outwardly in opposite directions therefrom along the major oval axis.
