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.
