  • Axial flow fan with multiple segment blades
    Publication number: 20040062654
    Abstract: An axial flow fan with a plurality of segment blades is described. The axial flow fan has a base, a hub and a plurality of blade units. The hub is mounted on, or pivots on, the base and supports the blade units. Each of the blade units is connected to a periphery of the hub and extends radially outward from the base has a plurality of segment blades. A segment space between the segment blades reforms a boundary layer of fluid passing over the segment blades and reduces the thickness of the boundary layer on the blade surfaces. As a result, the separation between the blade surfaces and fluid is avoided to maintain a laminar flow of the fluid adjacent to the segment blades.

  • Heat sink
    Publication number: 20040011508
    Abstract: This specification discloses a heat sink for coolers. The heat sink contains a heat conductive element, a heat dissipating shell covering over the heat conductive element, and a plurality of heat dissipating fins installed on the heat dissipating shell. The heat conductive element is comprised of a heat conductive plate and a heat conductive block installed at the center thereof. The area of the lower surface of the heat conductive block is greater than that of the upper surface thereof.
