Abstract
A solar collector device comprising a truncated dome shaped absorber with inner and outer wall defining an annular space wherein fluid to be heated passes is disclosed. The absorber is placed within a curved surfaced container which is transparent to infrared radiation. In one embodiment the surface of the container opposite the transparent side is provided with a reflective coating and the container is preferably substantially evacuated to reduce heat transfer from the absorber. In another embodiment the northerly side of the absorber is thermally insulated. The absorber is preferably black surfaced and when constructed of coiled tubing, the tubing is coiled in a cylindrical or domed configuration of one or more coils, and solar reflectors are positioned to provide reflected radiation to those sides of the absorber not receiving direct sunshine.
