<p>Solar collector comprises a parabolic or semicylindrical dish reflector (29) with an absorber in the form of a telescopic tube conveying a working medium in the focal plane (30) of the reflector. Independent claims are also included for: (1) A solar collector with a square or cylindrical absorber through which a working medium flows, where the absorber is designed as a base plate or floats in the working medium; (2) A solar collector with a spherical, hemispherical or lenticular absorber that is spanned at a distance by a transparent cover and with working medium supply pipe connected to a storage tank and with a working medium discharge pipe, where the supply pipe rises through the center of the absorber and the discharge pipe is at the apex of the cover; (3) A solar collector with an absorber that is spanned at a distance by a transparent cover and (verb missing) with working medium supply pipe connected to a storage tank and with a working medium discharge pipe, where the solar collector comprises a flexible container at the bottom and the flexible container is mounted in a metal frame and serves as the absorber or as an air bladder or a storage vessel for the working medium; (4) A solar collector with an absorber conveying a working medium, comprising externally perforated rails for holding a heat-insulating fabric; and (5) A water desalination apparatus comprising a solar collector as above as an evaporator, where salt water flows through the absorber as the working medium and and the apparatus comprises a device for collecting condensate.</p> |
