1. A heat dissipater having heat conductive rib with interval forming as flow guide hole and applied in electric luminous body, in which a heat conductive rib structure (310) being installed inside the heat dissipater, and the intervals defined by the heat conductive rib structure (310) is formed as flow guide holes (300) penetrating both sides axially and throughout, the contour of the heat dissipater (100) includes being formed in a cylindrical, conical, polygonal cylindrical or polygonal conical shape, a part of the outer bottom is combined with an intermediate heat conductor (102) where the electric luminous body (200) being installed, the flow guide holes (300) are not totally shielded after the intermediate heat conductor (102) being combined with the heat dissipater (100), the interior of the heat dissipater (100) is installed with the heat conductive rib structure (310) for being combined with the inner periphery of the heat dissipater (100), the bottom thereof is installed with the intermediate heat conductor (102), the intermediate heat conductor (102) is installed with the electric luminous body (200) and formed as the heat source, so the heat from the electric luminous body (200) can be conducted through the intermediate heat conductor (102) to the surface of the heat conductive rib structure (310) and the surface of heat dissipater (101), thereby forming a larger heat dissipation area for directly dissipating the heat, and with the fluid effect of hot ascent/cold descent, the airflow is enabled to upwardly flow from one side of the electric luminous body (200) through the flow guide holes (300) then flow out from the other side thereof thereby generating a cooling effect; the heat dissipater having heat conductive rib with interval forming as flow guide hole and applied in electric luminous body of the present invention utilizes the intervals defined by the heat conductive rib structure (310) for forming as the flow guide holes (300) penetrating both sides throughout, the heat dissipater (100) is further formed with flow guide holes allowing airflow to pass, and it mainly consists of:
heat dissipater (100): made of materials having great heat conductivity and heat dissipation property such as aluminum and copper, integrally formed or assembled by plural pieces; the interior of the heat dissipater is installed with a heat conductive rib structure (310), and the intervals defined by the heat conductive rib structure (310) are formed as flow guide holes (300) penetrating both sides axially and throughout, the contour of the heat dissipater (100) includes being formed in a cylindrical, conical, polygonal cylindrical or polygonal conical shape; one or both of the periphery and/or the inner annular surface thereof is formed as a planar or wavelike structure or one or both of the inner periphery and the outer periphery is formed as a structure having heat dissipation fins; heat conductive rib structure (310): made by materials having great heat conductivity, installed within the inner periphery of the heat dissipater (100), integrally formed or assembled with the heat dissipater (100), the heat conductive rib structure (310) is formed in a multiple grid state or formed in a multiple grid state having three or more sides; electric luminous body (200): constituted by light emitting diodes, or composed of other electric luminous body capable of converting electric energy into optical energy accompanying with heat being generated, the bottom of the heat dissipater (100) or the intermediate heat conductor combined therewith is installed with one or more of the electric luminous bodies (200), or the bottom of the heat conductive rib structure (310) or the intermediate heat conductor combined therewith is installed with one or more of the electric luminous bodies (200), or installed at both locations;
the heat from the electric luminous body (200) is conducted through the heat conductive rib structure (310) and dissipated to the exterior through the surface of heat dissipater (101), and with the heat dissipation surface enlarged by the heat conductive rib structure (310), a larger heat dissipation area is formed for directly dissipating the heat, and with the fluid effect of hot ascent/cold descent, the airflow is enabled to upwardly flow from one side of the electric luminous body (200) through the flow guide holes (300) then flow out from the other side thereof thereby generating a cooling effect; in the heat dissipater having heat conductive rib with interval forming as flow guide hole and applied in electric luminous body of the present invention, not only the flow guide holes (300) penetrating both sides throughout are formed at the intervals defined by the heat conductive rib structure (310), but the heat dissipater (100) can also be optionally formed with flow guide holes allowing airflow to pass, and the installation location of the flow guide hole includes installing one or more radial flow guide holes (303) in the heat dissipater (100). |
