According to one embodiment, a two-phase cooling system includes a condensing heat exchanger fluidly coupled to an evaporator assembly and a pressure controller. The condensing heat exchanger condenses a coolant from a vapor phase to a liquid phase by removing heat from the coolant. The evaporator assembly is thermally coupled to a vacuum tube and operable to receive liquid coolant from the condensing heat exchanger, cool the vacuum tube by evaporating the coolant from the liquid phase to the vapor phase, and transporting the evaporated coolant to the condensing heat exchanger. The pressure controller maintains the pressure of the coolant in the evaporator assembly at a sub-ambient pressure to lower the boiling point of the coolant for reducing the operating temperature of the vacuum tube. |
