    Abstract: A cooling apparatus for a medium voltage or high voltage switchgear includes an evaporator, a fluid conduit, and a condenser. The evaporator is configured to surround at least part of a current carrying contact. The fluid conduit fluidly connects the evaporator to the condenser. A section of the fluid conduit is formed within the evaporator and is electrically insulating and is configured such that fluid can contact an outer surface of the current carrying contact. The cooling apparatus is configured such that in use a working fluid in the evaporator is heated to a vapour state, and the vapour is transferred by the fluid conduit to the condenser. The vapour in the condenser is condensed to the working fluid. The condensed working fluid is passively returned via the fluid conduit to the evaporator.

    Abstract: A charger plug nozzle for plugging into a battery charge socket includes an inner enclosure enclosing at least one heat source, an outer enclosure enclosing the inner enclosure, at least one heat source inside the inner enclosure, and at least one heat conductor. A heat receiving part of the at least one heat conductor is located in an air gap inside the inner enclosure, and a heat dissipating part of the at least one heat conductor is located in an air gap inside the outer enclosure.
