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.
