Abstract
A solar heat collector made up of several metal plates, each bent to provide a first planar portion and a second planar portion at substantially 90.degree., with a flanged hole through each first portion. One or more metal tubes passes through the holes of the plates to position the plates with their second portions forming a substantially continuous sheet. Spacers maintain the plate spacing so that the plate second portions do not overlap. The tubes and flanges are sized so that the tubes are squeezed as they pass through the plate holes, assuring good thermal contact between the tubes and the plates.
