Abstract:
A structure for cooling an electronic device is disclosed. The structure includes a solid heat-conducting layer disposed over the electronic device. The solid heat-conducting layer is a planar surface in contact with the electronic device. The structure further includes a plurality of copper spring elements disposed between the solid heat-conducting layer and the electronic device for providing a heat path from the electronic device and wherein the plurality of spring elements extend in an upper direction away from the electronic device and wherein the plurality of spring elements include a spring for offering resistance when loaded and wherein the spring elements have a smaller profile at a first end in contact with the electronic device, wherein the profile increases in size at a second end in contact with the solid heat-conducting layer.
