Fan frame and heat dissipation fan incorporating the fan frame

摘要

A fan frame (20) includes a bracket (22) and a base (24). The bracket includes a sidewall (225). An air inlet (228) is defined in a top side of the sidewall. An opposite air outlet (229) is defined in a bottom side of the sidewall. A plurality of first locking units (227) are formed on the sidewall. The base includes a main body (240), a plurality of ribs (242) and a plurality of second locking units (245). Each rib has a fixed end (2421) connected with the main body, and an opposite free end (2422). Each second locking unit is formed at the free end of a corresponding rib. The second locking units are detachably interlocked with the first locking units to mount the base to the bracket thereby to form the fan frame. The bracket and base are formed by materials having different strengths.
