Abstract
The invention provides a heat sink device for receiving heat generated by an electrical chip. The heat sink device includes a cold plate having a bottom surface for receiving heat from the electrical chip and a top surface opposite of the bottom surface. The heat sink device also includes a finger member having a rounded tip centered on the top surface. The heat sink device also includes a force generating device having an anvil spaced from the finger member and a compressible member compressed between the anvil and the finger member. The compressible member generates a pressing force urging the finger member and the top surface together. The heat sink device also includes a moving device operable to move one of the anvil and the finger member relative to the other to change the pressing force generated by the compressible member.
