Abstract

An apparatus for spreading heat over a plurality of fins is provided. The apparatus includes a heat dissipating member composed of metal and having a plurality of fins on a first side of the heat dissipating member. The apparatus also includes a plurality of strips of thermal material having a thermal conductivity in a direction parallel to the heat dissipating member higher than a thermal conductivity of the heat dissipating member, the plurality of strips disposed on a side of the heat dissipating member opposite of the first side and configured to spread heat along the heat dissipating member.
