Abstract
A heat sink for a computer chip is adapted for mounting to a heat exchange plate that has elongate slots with limited clearance on the other side. Mounting apparatus includes latch pins with an elongate knob at the end to have a T-shape with a reduced shaft to define a shank and collar that are so sized as to control the projection of the knob beyond the slot. Specially bent flexible members are preferably interposed between the collar and heat sink to force intimate engagement with the heat exchange plate.
