  • Patent number: 10544995
    Abstract: A heat transport device includes a heat pipe having a capillary container having a wick and a working fluid arranged therein. A first heat source is coupled to a first end of the capillary container to define an evaporator section and a cold sink is coupled to a second end of the capillary container to define a condenser section. A capillary pump includes an evaporator and a reservoir configured to store an additional supply of working fluid. A second heat source coupled to the evaporator is configured to vaporize the working fluid arranged therein. A fluid loop couples the capillary pump to the heat pipe. Upon detection of a predetermined condition indicative that a majority of the working fluid within the heat pipe is frozen, the capillary pump is configured to supply vaporized working fluid to the heat pipe.

  • Patent number: 10436521
    Abstract: A system may include a pump, an evaporator, a condenser, an accumulator, a pump bypass line, a first valve, and a second valve. The system may operate in a powered-pump mode, in which the pump drives fluid circulation, the first valve prevents fluid circulation through the pump bypass line, the pump pumps liquid from the accumulator to the evaporator, gas exiting the evaporator flows to the condenser, liquid exiting the evaporator flows through the second valve to the accumulator, and liquid exiting the condenser flows to the accumulator. The system may operate in a passive-capillary mode, in which capillary pressure in the evaporator drives fluid circulation, the first valve prevents fluid circulation through the pump, liquid flows from the accumulator, through the pump bypass line, and to the evaporator, gas exiting the evaporator flows to the condenser, the second valve is closed, and liquid exiting the condenser flows the accumulator.

  • Publication number: 20190234693
    Abstract: A thermal management loop system may include an accumulator, an evaporator in fluid receiving communication with the accumulator, a condenser in fluid receiving communication with the evaporator, and a rotary separator in fluid receiving communication with the condenser. Gas exiting the rotary separator may recirculate back to the condenser and liquid exiting the rotary separator may flow to the accumulator. The thermal management loop system may be a dual-mode system and thus may be operable in a powered-pump mode or a passive-capillary mode.
