Abstract: The invention provides an anti-fracture fan structure including a hub, a plurality of blades, and a plurality of ribs. The hub has an inner surface formed inside and encircling it. The plurality of blades are arranged outside and around the hub. The plurality of ribs projects from the inner surface of the hub into the inside of the hub. Each of the plurality of ribs is not perpendicular to the inner surface of the hub. Furthermore, the anti-fracture fan further includes a shielding-can situated inside the hub and in contact with the plurality of ribs. Moreover, the hub can be formed of a plastic material and the shielding-can can be formed of a metal material. The ribs can be easily warped when the shielding-can expands.

Abstract: An engagement structure of a fan, which is engaged with a heat dissipation plate having a plurality of heat dissipation fins. A plurality of lower engagement portions with inverted-L-shapes is formed on the plurality of heat dissipation fins. A plurality of clearances substantially parallel to the plurality of heat dissipation fins is formed on each of the lower engagement portions. The engagement structure includes a fan frame and a plurality of upper engagement portions with L-shapes. The plurality of upper engagement portions is elastically mounted around the fan frame. Each of the upper engagement portions includes an L-shaped portion. A plurality of ribs is formed on the L-shaped portions. When assembling the engagement structure with the heat dissipation plate, the L-shaped portions are engaged with the lower engagement portions with inverted-L-shapes for mounting in a vertical direction, while the plurality of ribs are engaged with the plurality of clearances for mounting in a horizontal direction.
