ABSTRACT:
A cooling system for providing cryogenic cooling fluid to a thermal load, the system comprising: a main cryogenic refrigeration system; a cryogenic cooling fluid feed line having a feed line outlet coupled to the thermal load and a feed line inlet coupled to the cryogenic refrigeration system; a cryogenic cooling fluid return line having a return line inlet coupled to the thermal load and a return line outlet coupled to the cryogenic refrigeration system; a bypass cooling system further comprising isolation valves attached to the feed line and return line wherein each of said valves has a closed position and an open position, a bypass line extending between the feed line and return line, a bypass valve and a cooling device attached to one of said feed line and return line. The bypass cooling system may further include a cold box housing the bypass line and the cooling device, e.g., an open or closed heat exchanger coupled to a storage tank of cryogen.
