Venetian blind type solar heater

Abstract

A venetian blind type solar heater. The top outer half of the slats are coated with a heat absorbing material while the rest of the slats are coated with a non-heat absorbing material. Thermal conduction in the metal slats heats the entire slat. The distance between the slats are half the width of the slat so that the slats overlap. The number of slats increases thereby increasing the total surface area available for heat transfer to the inside room air by convection and thermal radiation. When the orientation of the slats are reversed the heat absorbing surface area is shielded from outside solar radiation and any stray inside room radiation.

What I claim as my invention:  
     
         1 . A solar collector that provides shielding of the solar radiation absorbing surface area while improving heat transfer to inside room air. Said collector being metal slats coated with a heat absorbing material on the top outer half of said slat.  
     
     
         2 . The collector as recited in  claim 1  the further improvement being the thermal conductance of the metal raises the temperature of the slats entire surface area allowing heat transfer from non exposed surface areas.  
     
     
         3 . The collector as recited in  claim 1  the further improvement being the number of slats added to allow for overlapping and shielding of the heat absorbing area increases the total surface area available for transfer of heat to inside room.
