Abstract:
A heat sink retaining apparatus for thermally and mechanically coupling a surface of a heat sink to a device requiring assisted cooling, said apparatus comprising:a biasing member comprising a biasing bar having a longitudinal axis, a first lever connected to said biasing bar at a first position on said biasing bar along said longitudinal axis and radially extending from said longitudinal axis for engagement with said heat sink, and means for mounting said biasing member proximate said device and said heat sink, said means for mounting comprising a support fixedly connected to said biasing bar at a second position on said biasing bar along said longitudinal axis, said first lever stressing said biasing bar by rotating said biasing bar at said first position about said longitudinal axis of said biasing bar relative to said second position as said first lever is brought into an engaged position against said heat sink so as to create a biasing force which biases said first lever against said heat sink when said lever is in said engaged position, wherein said means for mounting said biasing member proximate said device and said heat sink are operatively arranged so as to maintain said first lever in said engaged position such that said biasing force is transferred through said first lever to said heat sink to thermally and mechanically couple said heat sink to said device.
