1. A passive cooling system, comprising:
a heat exchanger thermally connected to a heat-generating component located within an enclosure;
a distribution manifold located below the heat exchanger;
a condensing unit located external to the enclosure and above the heat exchanger;
a first conduit fluidly connected to the heat exchanger, the distribution manifold, and the condensing unit;
a second conduit fluidly connected to the condensing unit and the distribution manifold;
a liquid bridge fluidly connected to the first conduit and the second conduit or the distribution manifold; and
a two-phase cooling medium that circulates through a loop defined by the first conduit, the liquid bridge, the condensing unit, the second conduit, the heat exchanger, and the distribution manifold,
wherein the liquid bridge transfers the cooling medium in a liquid state from the first conduit to the second conduit or the distribution manifold, and
wherein the liquid bridge comprises a tubular member positioned at an inclined angle between the first conduit and the second conduit or the distribution manifold.
