Cup-shaped heat dissipater having flow guide hole annularly arranged at the bottom periphery and applied in electric luminous body

摘要

The present invention provides a novel cup-shaped heat dissipater (100) having the outer cup bottom of the cup-shaped heat dissipater formed as a planar or convex or concave surface for accommodating the electric luminous body (200), so the heat can be dissipated to the exterior from the surface of the heat dissipater (100), and with the enlarged heat dissipation surface formed in the cup-shaped inner recessed structure of the heat dissipater (100) opposite to the installation location of the electric luminous body (200), the heat can also be directly dissipated through the larger heat dissipation area, furthermore, flow guide holes allowing airflow to pass are formed on the heat dissipater (100) for performing heat dissipating convection through the heat dissipating fluid.
