  • This invention relates to a heat-radiating member having excellent heat-radiation performance, a device that uses that heat-radiating member, a casing, a computer-support stand, and a method for manufacturing the heat-radiating member.
  • the heat-radiation unit that manages that heat radiation for example, a heat-radiation fin, muffler of an internal-combustion engine, various kinds of electric motors, heat sinks or the like, have been treated with a black coating to improve the heat-radiation effect.
  • the construction of the heat-radiation unit is specially designed (for example, construction that promotes heat convection, etc.) in order to improve heat-radiation effect.
  • An example of this is simple construction that comprises a circuit component that is equipped with a plurality of busbars of an electric power circuit, and a heat-radiating member having a busbar-bonding surface that is coated with an insulation layer; and by arranging the plurality of busbars on this busbar-bonding surface such that each busbar is directly bonded to the busbar-bonding surface, the busbars are efficiently cooled (see Japanese patent publication 2003-164040).
  • an electrical-wiring box in which an insulation board that is supported and located in a space between a current-distribution circuit board and printed-circuit board is eliminated, and the heat-radiation performance is improved by the existence of the space (for example, see Japanese patent publication 2003-87938).
  • the object of this invention is to provide a heat-radiating member, device that uses that heat-radiating member, casing, computer-support stand and method for manufacturing the heat-radiating member that make it possible to expect more heat-radiation effect than from a heat-radiating member that is treated with a black coating.
  • the inventor of this invention applied various sample materials to a base material and tested the heat-radiation state, and found that tourmaline had very remarkable effect (discovered specified attributes), then as a result of dedicated research, found from among various kind of tourmaline existing in nature such as dravite tourmaline, schorl tourmaline, mixed tourmaline, lithia tourmaline, etc., a tourmaline that provided an excellent heat-radiation effect, and further found, even for that tourmaline which had excellent heat-radiation effect, the existence of a grain diameter and a density (amount of coating) per unit area that provided outstanding heat-radiation effect.
  • the inventors focused on a specific tourmaline and used that tourmaline powder (exclusively used those properties and attributes) to invent a heat-radiating member capable of solving the aforementioned problem.
  • the heat-radiating member comprises a tourmaline layer that is formed by mixing schorl tourmaline powder having a grain diameter of 3 to 7 ⁇ m with a liquid-form fixing agent to form a coating agent, 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.
  • the heat-radiating member is formed by mixing schorl tourmaline powder having a grain diameter of 3 to 7 ⁇ m with a base material made from aluminum.
  • the heat-radiating member is formed by mixing schorl tourmaline powder having a grain diameter of 3 to 7 ⁇ m with a base material made from plastic.

  • reference number 11 indicates the base material
  • reference number 12 indicates the tourmaline layer.
  • the heat-radiating member 1 of this embodiment comprises: a base material 11 made from a thin copper plate (0.8 mm plate thickness) having high heat conductivity; and a tourmaline layer 12 , having schorl tourmaline powder as the main component, coated on the top surface of that base material 11 .
  • This tourmaline layer 12 is formed by mixing schorl tourmaline powder, having a grain size of 6 ⁇ m, with a fixing agent made from an acrylic volatile synthetic resin coating material at a weight ratio of 1:1 (coating formation step) to form a coating, and then coating the base material 11 with multiple coats of that coating material until the density of the tourmaline powder becomes 0.025 to 0.05 grams per cm 2 (coating step), and finally letting the coating harden.
  • Typical tourmaline such as dravite tourmaline, schorl tourmaline, mixed tourmaline, or lithia tourmaline were used to perform preliminary heating tests, and a blackened schorl tourmaline having the best heat-radiation effect was employed.
  • the reason that the weight ratio of fixing agent to schorl tourmaline powder is made to be 1:1 is that it has been confirmed through testing that when the fixing agent dries and hardens there is a good balance in order to maintain the dense state of the schorl tourmaline powder; and when the amount of fixing agent is less than the amount of schorl tourmaline powder it becomes easy for the tourmaline to peal from the base material, and when the amount of fixing agent is greater than the amount of schorl tourmaline powder, multiple coats are required in order to obtain the desired schorl tourmaline density, so workability becomes poor. Moreover, when 20 g of liquid-state acrylic volatile synthetic resin coating material dries it becomes 4 g.
  • the liquid in which this schorl tourmaline powder is mixed is not limited to the acrylic volatile synthetic resin coating material mentioned above, and it is also possible to use a well known heat-resistant coating material such as a water-based emulsion type coating material, or a two-component epoxy coating material, or in other words, any liquid material could be used as long as it will harden and not easily peal from the base material 11 (maintained in a coated state over a long period of time).
  • schorl tourmaline powder having a grain size of 3 to 7 ⁇ m can be mixed with the molten aluminum or plastic base material and allowed to harden in a desired shape.
  • Tourmaline (not limited to schorl tourmaline) is broken down by applying heat of 900° C. or more, so aluminum, which has excellent heat conductivity, and a melting point of 660° C. is the most suitable material to use in the case where the base material itself contains schorl tourmaline powder as described above.
  • the pellets and schorl tourmaline powder are mixed at a weight ratio of 10%, and it is possible to manufacture a heat-radiating member having a desired shape using conventional molding means such as typical injection molding.
  • comparison sample A a 0.8 mm thick copper plate base material 11 , of which only the top surface was coated black
  • comparison sample B that base material 11 as is
  • temperature sensors C were attached to part of the surfaces of the tourmaline layer 12 and the side opposite from the black coated surface (for just comparison sample B there is no direction of the application surface of the temperature sensor), and the heat-radiating member 1 and either comparison sample A or comparison sample B are selected, and the two are simultaneously placed on the top of a home-use heating appliance (hot plate) D.
  • a home-use heating appliance hot plate
  • the tourmaline layer 12 and the black coating are placed so that they are on the top, and the heat-radiating member 1 and comparison sample A or comparison sample B are place on the home-use heating appliance D so that the temperature sensors C are away from the heating appliance so that they are not affected by the heat of the home-use heating appliance D itself.
  • the temperature of the members placed on the top of the home-use heating appliance D rises to a suitable temperature, and by measuring the rise in temperature at that time away from the home-use heating appliance D, it is possible to know the state of heat radiating from the top surface.
  • the material of the base material 11 itself, the placement conditions, and heating conditions are the same, it is possible to gain an understanding of the heat-radiation effect of each member in the case in which there is a black-coated layer formed on the surface of the base material 11 , when there is a tourmaline layer 12 and when there is no formation layer.
  • the heat-radiating member 1 of this embodiment had better heat-radiation effect than both comparison sample A and comparison sample B. Also, the heat-radiating member 1 of this embodiment is constructed such that it has a thin plate shape, so the cutting process and bending process are simple, and processing can be performed so that it can be applied to various kinds of heat-radiating sections.
