1. A device comprising:

  • a housing that is moveable through a plurality of orientations involving at least two dimensions during usage;

    a heat-generating device disposed within the housing; and

    a heat transfer device disposed within the housing comprising;

    a thermal storage enclosure disposed proximal to the heat-generating device and configured to transfer heat from the heat-generating device using thermal conductivity and phase transition by a phase change material included within the thermal storage enclosure, the phase change material configured to undergo the phase transition at a temperature above a first temperature achieved by the heat-generating device operating at a low power state and below a second temperature achieved by the heat-generating device operating at a high power state; and

    a plurality of enclosed heat pipes configured to;

    transfer heat using thermal conductivity and phase transition from the thermal storage enclosure;

    the plurality of enclosed heat pipes arranged to;

    transfer heat from the heat-generating device during movement of the housing through the plurality of orientations;

    the plurality of enclosed heat pipes including;

    first and second heat pipes arranged in opposing directions, each of the first and second heat pipes having an evaporator portion and a condenser portion, the condenser portions of the first and second heat pipes are positioned further from each other than the evaporator portions of the first and second heat pipes, each of the plurality of enclosed heat pipes including the same phase change material within the thermal storage enclosure or a different phase change material configured to undergo a different phase transition than the phase transition of the phase change material within the thermal storage enclosure.
