1. An apparatus for transferring heat from a heat source to air in a state where the apparatus is connected to the heat source, the apparatus comprising:
a heat sink comprising a heat sink base and a plurality of primary fins connected to the heat sink base; and
a heat sink front,
wherein the heat sink base is configured to be thermally coupled to the heat source,
wherein each primary fin of the plurality of primary fins comprises one or more conduits,
wherein the heat sink base comprises a first chamber,
wherein the first chamber and the one or more conduits together form a common space sealed off from the ambient air surrounding the apparatus,
wherein the first chamber and the one or more conduits together enclose a heat-carrying fluid in the common space formed by the first chamber and the one or more conduits,
wherein, at the heat sink front, the one or more conduits of a first primary fin of the plurality of primary fins are sealed off from the one or more conduits of a second primary fin of the plurality of primary fins,
wherein the first primary fin opens into a first condenser chamber and the second primary fin opens into a second condenser chamber, and
wherein flaps are provided between the first condenser chamber and the second condenser chamber.
