| 摘要 |
The present invention provides a cup-shaped heat dissipater having heat conductive rib and flow guide hole, in which the outer cup bottom of the cup-shaped heat dissipater (100) is formed as a planar or convex or concave surface for accommodating the electric luminous body (200), so with the heat dissipation surface formed opposite to the cup-shaped inner recessed structure of the heat dissipater (100) and with the heat conductive rib structure (310) connecting between the inner periphery of the cup-shaped inner recessed structure of the heat dissipater (100) and the heat source zone having its bottom being installed with the electric luminous body (200) and the solid or tubular central column (103), the heat in the central heat source zone can be dissipated to the periphery through the surface of the heat conductive rib structure (310) and the surface of the heat dissipater (100). |
