1. A thermal management system comprising:
an immersion tank;
a working fluid at least partially positioned in the immersion tank, wherein the working fluid provides an immersion bath configured to have a heat-generating component at least partially immersed therein;
a heat exchanger configured to transfer thermal energy from the working fluid to ambient air to cool the working fluid;
a first fluid conduit providing fluid communication from the immersion tank to the heat exchanger; and
a second fluid conduit providing fluid communication from the heat exchanger to a spray nozzle to spray working fluid into a headspace of the immersion tank above the immersion bath, the spray of working fluid configured to condense at least a portion of a vapor phase of the working fluid into the immersion bath.
