Cooling system with a passive heat dissipation structure

Abstract

The present invention discloses a cooling system with a passive heat dissipation structure, the cooling system includes plural heat conducting pipes, and a shielding tube included to surround the heat conducting pipes. The heat generated from a heat source placed below the cooling system heats the surrounding fluid (air) and turns it into heated fluid. The heated fluid is lower in density and is dissipated away through convection by the heat conducting pipes, leaves its original space to cooler fluid (at room temperature). The mixing of the heated fluid with the cooler fluid can be prevented by the heat conducting pipes, and the heat convection of the heat source by the cooler fluid is increased. With the implementation of the present invention, the benefits of easy implementing, easy to use, requiring no extra energy and saving costs are achieved, and the heat of the heat source is promptly dissipated away.

 a shielding tube being an upright hollow-core pipe and having an upper opening facing upward and a lower opening facing downward; and   a plurality of flow-guiding pipes fixed to the shielding tube from inside to form the passive heat dissipation structure, wherein the flow-guiding pipes are each a hollow-core pipe with a first opening facing upward and a second opening facing downward, the first opening being higher than the second opening.   
     
     
         2 . A cooling system with a passive heat dissipation structure, comprising a plurality of flow-guiding pipes coupled together to form the passive heat dissipation structure, wherein the flow-guiding pipes are each a hollow-core pipe with a first opening facing upward and a second opening facing downward, the first opening being higher than the second opening. 
     
     
         3 . The cooling system of  claim 1 , wherein the flow-guiding pipes are upright. 
     
     
         4 . The cooling system of  claim 1 , wherein the flow-guiding pipes are oblique. 
     
     
         5 . The cooling system of  claim 1 , wherein the flow-guiding pipes are upright or oblique. 
     
     
         6 . The cooling system of  claim 2 , wherein the flow-guiding pipes are upright. 
     
     
         7 . The cooling system of  claim 2 , wherein the flow-guiding pipes are oblique. 
     
     
         8 . The cooling system of  claim 2 , wherein the flow-guiding pipes are upright or oblique. 
     
     
         9 . The cooling system of  claim 1 , wherein a heat source is fixed to the shielding tube from inside and positioned proximate to the lower opening, wherein a hot fluid from the heat source enters the second opening and exits the first opening. 
     
     
         10 . The cooling system of  claim 1 , being vertically fixed to a heat source from above, wherein a hot fluid from the heat source enters the lower opening, passes the second opening, and exits the first opening. 
     
     
         11 . The cooling system of  claim 2 , being vertically fixed to a heat source from above, wherein a hot fluid from the heat source enters the second opening and exits the first opening.
