Patent ID: 7843693

Claim:
A system for removing heat comprising: a sealed container; an evaporator, housed within the sealed container, for thermal communication with a heat source, the evaporator comprising an evaporator inlet, a plurality of tubes, each tube having a tube inlet connected to the evaporator inlet, and a tube outlet to the sealed container, each tube containing at least one substance; a condenser, housed within the sealed container, the condenser comprising a plurality of condenser inlet ports from the sealed container, a condenser outlet, and a plurality of condenser channels connecting the plurality of condenser inlet ports with the condenser outlet; and a conduit joining the condenser outlet to the evaporator inlet, whereby as the substance comes in thermal communication with the heat source, the substance changes from liquid to gas and moves out of the evaporator, the expanded volume forces the gas along a gas pathway within the sealed container and into one of the condenser inlet ports where it changes from gas to liquid as the substance travels along the length of the condenser channel, and the liquid is wicked from the condenser outlet through the conduit and into the evaporator inlet, wherein the conduit joining the condenser outlet to the evaporator inlet is surrounded by the gas pathway.
