Solar Heat Exchange Apparatus

Abstract

A solar heat exchange apparatus includes a heat holding base having a face with a plurality of heat collecting channels. Each heat collecting channel has an open end in the face of the heat holding base. A conduit extends through the heat collecting channels and is coated with a photothermal material. A plurality of light reflecting boards is mounted on the face of the heat holding base and located corresponding to the heat collecting channels and spaced from each other. Two adjacent light reflecting boards are slanted to define a light reflecting space located above and tapering towards one of the heat collecting channels. A light transmitting board is mounted on top sides of the light reflecting boards. The light transmitting board includes a plurality of light concentrating portions each of which is aligned with one of the light reflecting spaces.

1 . A solar heat exchange apparatus comprising:
 a heat holding base including a face and a plurality of heat collecting channels, with each of the plurality of heat collecting channels having an open end in the face of the heat holding base;   a conduit extending through the plurality of heat collecting channels and coated with a photothermal material;   a plurality of light reflecting boards mounted on the face of the heat holding base and located corresponding to the plurality of heat collecting channels, with the plurality of light reflecting boards spaced from each other, with two adjacent light reflecting boards being slanted to define a light reflecting space located above and tapering towards one of the plurality of heat collecting channels; and   a light transmitting board mounted on top sides of the plurality of light reflecting boards, with the light transmitting board including a plurality of light concentrating portions, with each of the plurality of light concentrating portions aligned with one of the light reflecting space.   
     
     
         2 . The solar heat exchange apparatus as claimed in  claim 1 , with a pair of light reflecting boards on opposite sides of each of the plurality of heat collecting channels together defining a heat reservoir space. 
     
     
         3 . The solar heat exchange apparatus as claimed in  claim 2 , with each of the heat reservoir spaces receiving a greenhouse gas or a heat storage material. 
     
     
         4 . The solar heat exchange apparatus as claimed in  claim 2 , with at least one leg provided on a bottom of each of the plurality of light reflecting boards, with said at least one leg extending into one of the heat reservoir spaces and in intimate contact with the face of the heat holding base. 
     
     
         5 . The solar heat exchange apparatus as claimed in  claim 3 , with at least one leg provided on a bottom of each of the plurality of light reflecting boards, with said at least one leg extending into one of the heat reservoir spaces and in intimate contact with the face of the heat holding base.
