Abstract
A technique for dissipating heat generated by a chip in a small, inexpensive, quiet, and reliable manner without drawing power from a power source. In a preferred embodiment, the chip resides in a computer housing and a heat dissipator for the chip is made up of a convection component and a conduction component. The convection component is similar to a conventional heat sink. It includes fins that channel a flow of air therethrough releasing heat into the air. The conduction component is a thermal conductor which attaches to a heat spreader. In the preferred embodiment, the heat spreader is part of the computer housing.
