Patent ID: 7336493

Claim:
Cold plate cooling apparatus for a rack mounted electronic module having a substantially planar lower surface, comprising: a cold plate having a substantially planar upper surface; a first thermally conductive block having a substantially planar lower surface adapted for heat transferring contact with said cold plate upper surface and a substantially planar side surface extending upwardly from said first block lower surface at a predetermined acute angle; a second thermally conductive block having a substantially planar lower surface adapted for heat transferring contact with said cold plate upper surface and a substantially planar side surface extending upwardly from said second block lower surface at said predetermined acute angle, wherein said second block side surface faces and is spaced from said first block side surface; a third thermally conductive block having a substantially planar upper surface adapted for heat transferring contact with said module lower surface, a first substantially planar side surface extending downwardly from said third block upper surface from a first line at said predetermined acute angle to said third block upper surface, and a second substantially planar side surface extending downwardly from said third block upper surface from a second line at said predetermined acute angle to said third block upper surface, wherein said first line is parallel to said second line and wherein said third block is positioned between said first and second blocks with said third block first side surface parallel to said first block side surface and said third block second side surface parallel to said second block side surface; and means for applying a force to move said first block toward said second block so as to force said first and second block side surfaces into heat transferring contact with said third block first and second side surfaces, respectively, force said third block upwardly so that said third block upper surface is in heat transferring contact with said module lower surface, and force said first and second blocks downwardly so that said first and second block lower surfaces are in heat transferring contact with said cold plate upper surface.
