Patent ID: 7280363

Claim:
A heat sink device for receiving heat generated by an electrical chip comprising: a cold plate having a bottom surface for receiving heat from the electrical chip and a top surface opposite of said bottom surface; a finger member having a tip centered on said top surface and a blind aperture extending between an open end and a closed end of said finger member; a force generating device having an anvil extending through said open end and spaced from said closed end and a compressible member disposed in said blind aperture and compressed between said anvil and said closed end of said finger member to generate a pressing force at least partially normal to said cold plate urging said finger member against said top surface; a frame operable to be at least one of substantially fixed and slidably disposed relative to the electrical chip and having a threaded aperture; and a moving device operable to move said anvil relative to said finger member to change said pressing force generated by said compressible member, wherein said moving device includes a threaded shaft received for rotation in said threaded aperture and fixed to said anvil to move said anvil during said rotation.
