  • Solar heat collector
    Patent number: 3981293
    Abstract: Disclosed is a solar heat collector having a cover plate mounted in spaced relation to a solar energy absorber. The cover plate has a transmittance coefficient (t) for solar radiation e.g., in the wavelength range of about 0.3 to 2.1 microns, and a reflectance coefficient (r) for infrared energy in the wavelength range of about 2 to 15 micron. The transmittance coefficient and reflectance coefficient of the cover plate are selected such that the product of (r) and (t) is equal to or greater than about 0.25 to increase the saturation temperature (T.sub.s) of the solar heat collector.
