Abstract
A heat sink retaining bracket having a first surface for engaging a heat sink and a second surface for engaging a chassis wall or other substantially rigid support member. The first surface may include an opening having a rim around its periphery. The rim may be adapted to engaged the top and sides of the heat sink such that sideways and upward translational movements are restrained. Air may pass through the opening as it enters or exits the heat sink so that the cooling efficiency of the heat sink is not substantially impaired by the bracket. The second surface may be adapted to engaged the chassis wall or support member using a hook-and-slot arrangement and a fastener or fasteners. In one embodiment, the fastener or fasteners may be applied in a compression mode. In another embodiment, the fastener or fasteners may be applied in a tension mode.
