ABSTRACT:
An electronic system having components operating at low temperature at various locations within the system, cryogenic fluid and electrical power are distributed by means of the same conduit. In one embodiment, the conduit consists of a supply section and a return section with each section comprising a channel for conveying cryogenic fluid having superconducing walls for conveying electrical power. In another embodiment of the invention, the conduit comprises a copper rod having channels formed therein for the transport of cryogenic fluid and a channel for supporting a rod of superconducing material therein. The superconducing rod conducts electrical current to a subsystem while being cooled by cryogenic fluid in nearby channels and the cryogenic fluid is used at its destination for cooling purposes. In yet another embodiment of the invention, cryogenic fluid is transported between a source of cryogen and subsystems using the fluid, by means of a pair of concentric conduits with the walls of each conduit comprising superconducting material for simultaneously providing electrical power to the subsystems employing the cryogenic fluid.
