1. An apparatus adapted to dissipate heat comprising:
a heat source,
a heat sink,
a heat conducting element,
wherein the heat conducting element conducts heat energy from the heat source to the heat sink along a heat conducting path, and wherein the heat conducting element is arranged in such a way on the heat source and the heat sink and is configured to physically change in such a way with increasing temperature of the heat conducting element that at least one of: a) a first cross-sectional area between the heat source and the heat conducting element increases, b) a second cross-sectional area between the heat conducting element of the heat sink increases, and c) a length of the heat conducting path shortens,
a control element that receives thermal energy from the heat source and exerts increasing pressure on the heat conducting element as the temperature rises, and
a lever with a first lever arm and a second lever arm, the control element adapted to exert an increasing pressure on the first lever arm as the temperature rises, so that the second lever arm exerts a pressure on the heat conducting element via the heat sink.
