Tube type solar air heater

Abstract

The present invention relates to a tubular solar air heater, and more particularly, to a tubular solar air heater having a black hot air tube of a predetermined section into which cold air can be introduced formed at an inside of a tube which is formed transparently or semi-transparently, and allowing the cold air to be heated by solar heat in the hot air tube and discharged to the outside, thereby enabling radiant heating. The present invention includes a tube main body formed of a transparent or semi-transparent material, and a hot air tube which is formed to be penetrated at an inner portion of the tube main body, has a black-colored surface or back surface, and allows the cold air to be introduced thereinto, heated by solar heat, and discharged to the outside.

1 . A tubular solar air heater comprising:
 a tube main body formed of a transparent or semi-transparent material configured as an air heater; and   a hot air tube, which is formed to be penetrated at an inner portion of the tube main body, has a black-colored surface or back surface, and when cold air is introduced into the hot air tube, allows the cold air to be heated by solar heat and discharged to the outside.   
     
     
         2 . The tubular solar air heater according to  claim 1 , wherein the hot air tube further comprises a blowing fan coupled to one end portion thereof to allow hot air, which results from heating introduced cold air by solar heat, to be promptly discharged to the outside. 
     
     
         3 . The tubular solar air heater according to  claim 1 , wherein the tube main body further comprises an adhesive plate at a rear surface thereof to be attached and fixed to a window or smooth surface. 
     
     
         4 . The tubular solar air heater according to  claim 1 , wherein the hot air tube is formed in a straight tube shape, and two or more hot air tubes are formed. 
     
     
         5 . The tubular solar air heater according to  claim 1 , wherein the hot air tube is formed in a zigzag shape, an air inlet is formed at a lower portion of one side surface thereof, and an air outlet is formed at an upper portion of the one side surface. 
     
     
         6 . The tubular solar air heater according to  claim 1 , wherein the hot air tube has an air inlet and air outlet formed at the opposite side of the adhesive plate, and the air inlet is formed at a lower portion and the air outlet is formed at an upper portion. 
     
     
         7 . The tubular solar air heater according to  claim 5 , wherein the hot air tube has an air suctioning fan coupled to the air inlet, and a blowing fan coupled to the air outlet. 
     
     
         8 . The tubular solar air heater according to  claim 6 , wherein the hot air tube has an air suctioning fan coupled to the air inlet, and a blowing fan coupled to the air outlet.
