1. A heat exchanger for removing heat energy from a heat generator, comprising:

  • a) a plurality of conduits for a working fluid arranged in an upright position of at least 45°

    , each conduit having;

    a1) an exterior wall anda2) at least one interior wall forming at least one evaporator channel and at least one condenser channel within the conduit, such that the at least one evaporator channel is structurally separated from the at least one condenser channel within the conduit by the at least one interior wall;

    b) a first heat transfer element for transferring heat into the at least one evaporator channel; and

    c) a second heat transfer element for transferring heat out of the at least one condenser channel, the second heat transfer element being disposed only on a portion of the exterior wall, said portion of the exterior wall directly contacting the at least one condenser channel;

    wherein the at least one condenser channel of each conduit extends from a first distribution manifold located on one end of the heat exchanger to a second distribution manifold located on an opposing end of the heat exchanger; and

    wherein the first heat transfer element is spaced apart from the portion of the exterior wall that directly contacts the at least one condenser channel; and

    the plurality of conduits are in fluid connection with one another at each end of the heat exchanger via the first and second distribution manifolds, wherein the at least one evaporator channel and at least one condenser channel are aligned in parallel in the plurality of conduits.
