Solar collector of fixed and concentrating flat panel type

Abstract

Disclosed herein is a solar collector of a fixed and concentrating flat panel type in which V-band type absorption plates each configured to have coating layers formed on both surfaces thereof and configured to maintain regular intervals are formed within the solar collector having a flat panel type and a reflection plate configured to reflect solar energy toward the absorption plates and to have an elliptical symmetry structure are disposed under the absorption plates. Accordingly, a solar energy absorption ratio can be maximized, and concentration efficiency can be improved.

1 . A solar collector of a fixed and concentrating flat panel type configured to comprise a hollow frame  28 , a cover  12 , and a transmission body  20 , and hollow absorption pipes  22  and rises  24  for supplying an external thermal medium and to have an insulator  14 , a reflection plate  16 , and absorption plates  18  sequentially disposed within the solar collector, wherein:
 the reflection plate  16  is configured to have an elliptical symmetry structure and to reflect solar energy toward the absorption plates  18  as much as possible with respect to an incident angle of the solar energy that varies according to each time zone. 
 
     
     
         2 . The solar collector of  claim 1 , wherein each of the absorption plates  18  has a V-band type structure in order to maximize an absorption ratio. 
     
     
         3 . The solar collector of  claim 2 , wherein coating layers  30   a  and  30   b  capable of maximize the absorption ratio are formed on the absorption plate  18 . 
     
     
         4 . The solar collector of  claim 3 , wherein the coating layers  30   a  and  30   b  are formed on both surfaces of the absorption plate  18 . 
     
     
         5 . The solar collector of  claim 3 , wherein the coating layers  30   a  and  30   b  are made of potassium persulfate, sodium hydroxide, and sodium carbonate. 
     
     
         6 . The solar collector of  claim 4 , wherein the coating layers  30   a  and  30   b  are made of potassium persulfate, sodium hydroxide, and sodium carbonate.
