An apparatus for heat dissipation is provided comprising a heat source, a heat sink and 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 a) a first cross-sectional area between the heat source and the heat conducting element and/or a second cross-sectional area between the heat conducting element of the heat sink increases, and/or b) a length of the heat conducting path shortens. Further, a video endoscope having such an apparatus and a use of such an apparatus are disclosed.
