Abstract
A cooling system including a heat spreader and a cooling element is described. The heat spreader is thermally coupled with a heat-generating structure. The cooling element is in fluid communication heat spreader. The heat-generating structure is offset from the cooling element. The cooling element undergoes vibrational motion when actuated to drive a fluid toward the heat spreader while not directing the fluid directly at the heat-generating structure.
Claims19
A cooling system, comprising:
- a heat spreader thermally coupled with a heat-generating structure;
- a cooling element in fluid communication heat spreader, the heat-generating structure being offset from the cooling element;
- and
- wherein the cooling element undergoes vibrational motion when actuated to drive a fluid toward the heat spreader while not directing the fluid directly at the heat-generating structure.
1 more element
A system, comprising:
- a heat spreader thermally coupled with a heat-generating structure;
- and
- an active cooling system including a plurality of active cooling cells, each of the plurality of active cooling cells including a cooling element, the active cooling system being in thermal communication with the heat spreader, wherein the cooling element undergoes vibrational motion when actuated to drive a fluid toward the heat spreader while not directing the fluid directly at the heat-generating structure, a combined thickness of the heat spreader and the active cooling system not exceeding four millimeters, the heat-generating structure being offset from the active cooling system.
A method, comprising:
