Fan assembly

A fan assembly for dissipating heat from an electronic device, the fan assembly comprising:

• a bracket having a pair of parallel retaining walls with a space formed therebetween, each retaining wall defining an opening and a recess;
• and
• a fan module, comprising a fan and at least one clamping member, the at least one clamping member attached to one side of the fan, two resilient arms formed on opposite sides of the clamping member, an engaging portion formed on each resilient arm corresponding to each recess, wherein each resilient arm is capable of being resiliently deflected by a respective one of the retaining walls when the fan module is slid into the space, and the engaging portions respectively engage with the corresponding recesses from an inner side of each retaining wall after the resilient arms rebound.

A fan assembly for dissipating heat from an electronic device mounted within a chassis, the fan assembly comprising:

• a bracket fixed within the chassis, the bracket comprising a pair of parallel retaining walls cooperatively defining a plurality of pairs of aligned openings, one recess being defined at each of opposite two sides of each of the openings;
• and
• a plurality of fan modules arranged between the retaining walls in a longitudinal direction of the retaining walls, each of the fan modules comprising a fan sandwiched between the retaining walls and aligned with one corresponding pair of aligned openings, and a pair of clamping members secured to opposite sides of the fan perpendicular to the retaining walls, a resilient arm being formed at each one of two opposite side edges of each of the clamping members and comprising an engaging portion engaging with a corresponding one of the recesses to thereby secure the fan to the bracket, wherein the engaging portion defines a slanted surface such that when the clamping members are lifted in a direction parallel to the retaining walls the slanted surface is capable of guiding the engaging portion sliding out from the corresponding recess.
