LEAK TOLERANT LIQUID COOLING SYSTEM EMPLOYING IMPROVED AIR PURGING MECHANISM

A cooling system for at least one thermal unit includes a tank assembly that includes: a sump chamber, a purge chamber that is located above the sump chamber, and a reservoir chamber that is located above the purge chamber; a cooling circuit that includes a pump, a heat exchanger, and conduits, the cooling circuit being configured to circulate a liquid coolant through the at least one thermal unit, the sump chamber, the pump, the heat exchanger, and the reservoir chamber; a first valve located externally of the tank assembly and configured such that, when the first valve is open, (i) the liquid coolant is flowable from the purge chamber to the sump chamber via the first valve, and (ii) air is simultaneously flowable from the sump chamber to the purge chamber via the first valve; and a second valve located externally of the tank assembly and configured such that, when the second valve is open, (i) the liquid coolant is flowable from the reservoir chamber to the purge chamber via the second valve, and (ii) air is simultaneously flowable from the purge chamber to the reservoir chamber via the second valve.
