Heat radiating member, device using the heat radiating member, casing computer support stand, and radiating member manufacturing method

Abstract

The heat-radiating member 1 shown in FIG. 1 with a tourmaline layer is formed by mixing schorl tourmaline powder having a grain diameter of 3 to 7 μm with a liquid-form fixing agent to form a coating agent, and then applying that coating agent to the surface of a base material, which is made from a metal such as copper, aluminum or the like having excellent heat conductivity, until the density of the schorl tourmaline powder is 0.25 to 0.05 grams per cm 2 , and allowing it to harden. With this construction, it is possible to provide a heat-radiating member, or devices or parts themselves that can be expected to have a better heat-radiation effect than a heat-radiating member whose base material is treated with a black coating.

1 . A heat-radiating member comprising a tourmaline layer that is formed by mixing schorl tourmaline powder having a grain diameter of 3 to 7 μm with a liquid-form fixing agent to form a coating agent, and then applying said coating agent to the surface of a base material, which is made from a metal such as copper, aluminum or the like having excellent heat conductivity, until the density of said schorl tourmaline powder is 0.25 to 0.05 grams per cm 2 , and allowing it to harden.  
   
   
       2 . A heat-radiating member that is formed by mixing schorl tourmaline powder having a grain diameter of 3 to 7 μm with a base material made from aluminum.  
   
   
       3 . A heat-radiating member that is formed by mixing schorl tourmaline powder having a grain diameter of 3 to 7 μm with a base material made from plastic.  
   
   
       4 . A device such as heat exchanger or various kind of appliances wherein a heat-generating section that generates heat, and/or a heat-radiating section that radiates heat is constructed using the heat-radiating member of  claim 1 .  
   
   
       5 . The heat-radiating member of  claim 4  wherein the device constructed using said heat-radiating member is a cooling device, and said heat-radiating member is used in the heat-exchange system of said cooling device.  
   
   
       6 . A case comprising an electric device such as a computer or hard disk drive and that is constructed using the heat-radiating member of  claim 1 .  
   
   
       7 . A computer support stand on which a notebook computer is placed and that is formed into an L shape as seen from the side and on which the heat-radiating member of  claim 1  is placed.  
   
   
       8 . A method for manufacturing a heat-radiating member comprising: 
 a coating-agent-creation step of creating a coating agent by mixing schorl tourmaline powder having a grain diameter of 3 to 7 μm with a fixing agent; and    a coating step of applying said coating agent onto the surface of a base material, which is made of a metal such as copper, aluminum or the like having excellent heat conduction, so that the density of said schorl tourmaline powder becomes 0.025 to 0.05 grams per cm 2 .    
   
   
       9 . A method for manufacturing a heat-radiating member wherein molten aluminum is mixed with schorl tourmaline powder, then molded and hardened into a desired shape.  
   
   
       10 . A method for manufacturing a heat-radiating member wherein liquid plastic is mixed with schorl tourmaline powder, then molded and hardened into a desired shape.
