PURPOSE:To prevent the stagnation of bubbles in liquid He under the state of nongravitation by a method wherein a forced convection device is attached in the liquid He. CONSTITUTION:Bubbles 3 are circulated without stagnation around a heat generating body using the fan 2 located in a liquid He vessel 1. According to this constitution, the quenching of a superconductive electromagnet or the damage of a conductor by burning is not generated even under the state of nongravitation, and the impossibility of recooling or becoming a superconductive condition can be prevented. |
