Abstract

An absorber for converting solar rays into thermal energy, in particular for use in a solar collector ( 10 ), is proposed, which comprises a non-porous dark ceramic, wherein the absorber is flowed through by a heat transport medium.

Claims

exact text as granted — not AI-modified
1 . Absorber for converting solar rays into thermal energy, in particular for use in a solar collector ( 10 ), which is flowed through by a heat transport medium, characterized in that the absorber ( 14 ) essentially comprises a non-porous, dark ceramic. 
     
     
         2 . Absorber according to  claim 1 , characterized in that the non-porous ceramic is a non-oxide ceramic on the basis of silicon carbide. 
     
     
         3 . Absorber according to  claim 2 , characterized in that the silicon carbide is present in technical form. 
     
     
         4 . Absorber according to one of the preceding claims, characterized in that the absorber is embodied in a tubular manner. 
     
     
         5 . Absorber according to  claim 4 , characterized in that the absorber ( 14 ) comprises a plurality of tubular elements ( 16 ,  16 ) densely connected to one another. 
     
     
         6 . Absorber according to  claim 5 , characterized in that the connection of two tubular elements ( 16 ,  16 ) is carried out by means of a slip joint. 
     
     
         7 . Absorber according to  claim 6 , characterized in that metal clamps are used to secure a slip joint. 
     
     
         8 . Absorber according to  claim 6  or  7 , characterized in that the seal of the slip joint is carried out by means of a silicon seal ( 46 ). 
     
     
         9 . Absorber according to  claim 6  or  7 , characterized in that the seal of the slip joint is carried out by a refractory putty or adhesive ( 44 ). 
     
     
         10 . Absorber according to one of the preceding claims, characterized in that a minor ( 12 ) reflecting solar rays onto the absorber ( 14 ) is provided. 
     
     
         11 . Absorber according to one of the preceding claims, characterized in that the heat transport medium preferably comprises silicon oil.
