Abstract
Abstract An apparatus including a heat sink compatible with a rail, the heat sink including two engagement windows that align with a corresponding pair of rail engagement windows when the apparatus is positioned in the rail. A handle engaged with the heat sink, the handle to enable a retention position and a retraction position of the apparatus. A first latch and a second latch laterally opposed and positioned within a first cavity and a second cavity, respectively, of the heat sink. A first spring and a second spring laterally opposed and positioned within the first and second cavities, respectively, of the heat sink, the first and second springs engaged with the handle and the first and second latches, wherein the first and second springs to push a first latch end of each latch into the rail engagement window when the apparatus is in a retention position, wherein the first and second springs to actuate the retraction of the first latch end of each latch when the handle is used to place the apparatus in a retraction position.
