Abstract
There is disclosed in one example a computing apparatus, including: an active computing element; a first magnetic attractor mechanically coupled to the active computing element; and a cold plate disposed to conduct heat away from the active computing element, the cold plate including a second magnetic attractor disposed to magnetically couple with the first magnetic attractor.
Claims25
A computing apparatus, comprising:
- an active computing element;
- a magnetically attractive mechanical stiffener affixed to a top surface of the active computing element;
- and
- a cold plate disposed to conduct heat away from the active computing element, the cold plate comprising a plurality of magnets disposed around a full periphery of the cold plate and disposed magnetically couple with the magnetically attractive mechanical stiffener.
1 more element
An apparatus, comprising:
- a heat source having disposed thereon a mechanical stiffener disposed peripherally around and attached to a top surface of the heat source;
- and
- a heat conductor configured to conduct heat from the heat source to an ambient environment, the heat conductor comprising a magnetic attractor having a plurality of magnets, the magnetic attractor having a length and width substantially matching a length and width of the heat source, wherein the heat conductor is disposed to mechanically couple to the heat source substantially via magnetic attraction between the mechanical stiffener and a plurality of magnets disposed around a full periphery of the heat conductor.
A heat spreader, comprising:
- a heat conductive surface configured to mechanically couple to a heat source, and having dimensions to substantially match a top profile of the heat source;
- and
- a first magnetic attractor disposed around a full periphery of the heat spreader to magnetically couple to a second magnetic attractor of the heat source, the first magnetic attractor comprising a plurality of magnets disposed around the full periphery of the heat spreader.
