Abstract

Official abstract text for this publication.

A system includes an electronic device, a heat spreader with a vapor chamber attached to a bottom end of the electronic device, so that heat flows from the electronic device to the heat spreader, and a heat sink with microchannels running through it attached to a bottom end of the heat spreader, so that heat from the heat spreader flows through the heat sink and to an ambient. A method for cooling a device includes transferring heat generated by a device through a conductivity layer, spreading the heat through a heat spreader, transferring the heat from the heat spreader to a heat sink that contains microchannels, and releasing the heat from the heat sink into an ambient.

First claim

Opening claim text (preview).

The invention claimed is: 1. A system comprising: an electronic device; a heat spreader with a vapor chamber attached to a bottom end of the electronic device, so that heat flows from the electronic device to the heat spreader, wherein the heat spreader comprises: a conductivity layer held at a top end of the heat spreader; a frame attached to a bottom side of the conductivity layer; and a vapor chamber in the frame that contains a working fluid that is capable of phase-cha…
