Heat sink for cooling an apparatus where heat is generated with cooling projections

摘要

The heat sink has a heat absorbing base plate (11) to which several cooling projections (12) are attached spaced uniformly apart. These projections have a hollow interior to lower the internal heat storage. The heat energy generated by a heat generating component (3) is transmitted quickly to the upper end of the projection (12) to enable rapid heat dispersion. The inside of the projections can contain a vacuum to increase the rate of heat dispersion. Alternatively the projections may be filled with a heat conducting material.
