Abstract:
1. An x-ray tube closed heat transfer system comprising: a pump for pumping fluid through the closed heat transfer system, said pump comprising a pump inlet and a pump outlet; a first phase change component in which said fluid undergoes a phase change from liquid to gas, wherein said first phase change component is an x-ray tube; a second phase change component coupled to said first phase change component, said fluid undergoing a second phase change from gas to liquid; a conduit for coupling said pump outlet to said first phase change component, said first phase change component to said second phase change component, said pump being upstream of said first phase change component; and a reservoir coupled to said conduit; said reservoir being situated downstream of said second phase change component and upstream of said pump inlet; said reservoir providing for a change in the ratio of liquid to gas as conditions change outside said closed heat transfer system.
