Patent ID: 6985359

Claim:
A variable-gap thermal-interface device for transferring heat from a heat source to a heat sink, said device comprising: a multi-axis rotary spherical joint comprising a spherically concave surface having a first radius of curvature in slideable contact with a spherically convex surface having said first radius of curvature; a first block having a proximal end coupled with said heat sink and a distal end rotatably coupled with a second block through said rotary spherical joint; a second block having a proximal end rotatably coupled with said first block through said rotary spherical joint and having a distal end opposite said proximal end; and a wedge having a variable thickness separating a first surface and a second surface, said second surface opposite and inclined relative to said first surface, said first surface thermally coupled with said distal end of said second block and said second surface thermally coupled with said heat source.
