Radiation heat collector

Abstract

In a radiation heat collector, comprising: a linear tubular heat collector member defining an internal passage for conducting fluid and a reflector having a reflecting surface partly surrounding the heat collector member, the reflector is rotatably supported around the heat collector member so that the angular position can be changed at will so as to optimize the orientation of the reflector for the given location, inclination of the solar collector, time of the year and time of the day.

1 . A heat collector, comprising: 
 a linear tubular heat collector member defining an internal passage for conducting fluid; and    a reflector having a reflecting surface partly surrounding said heat collector member;    said reflector being rotatably supported around said heat collector member.    
     
     
         2 . A heat collector according to  claim 1 , further comprising a powered actuator for rotating said reflector.  
     
     
         3 . A heat collector according to  claim 2 , further comprising a controller for operating said powered actuator according to a predicted motion of the sun.  
     
     
         4 . A heat collector according to  claim 1 , wherein said reflector is adapted to be turned to an angular position at which said reflector is located substantially above said heat collector member.  
     
     
         5 . A heat collector according to  claim 1 , wherein a plurality of heat collector members are arranged in a mutually parallel relationship, and are connected to one another in series via connecting pipes.  
     
     
         6 . A heat collector according to  claim 5 , further comprising a mechanism for synchronizing angular motion of said reflectors.  
     
     
         7 . A heat collector according to  claim 6 , further comprising a powered actuator for rotating said reflectors.  
     
     
         8 . A heat collector according to  claim 7 , further comprising a controller for operating said powered actuator according to a predicted motion of the sun.  
     
     
         9 . A heat collector according to  claim 6 , wherein said reflectors are adapted to be turned to an angular position at which each of said reflectors is located substantially above the corresponding heat collector member.
