<p>Cooling process of a current supply line between a terminal (7) at ambient temperature and an electrical unit operating at very low temperature with variable intensity, according to which an auxiliary cooling fluid at ambient temperature is made to flow under heat exchange with the current supply line starting from an intermediate level between the terminal at ambient temperature and the electrical unit at very low temperature, up as far as the terminal at ambient temperature, and device for implementation thereof. The auxiliary cooling fluid is introduced at an intermediate level (17A) of the current supply line when the intensity of the current exceeds a certain threshold and possibly all or part of the auxiliary cooling fluid is introduced at other levels (14A), which are all the closer to the electrical unit the higher the intensity of the current. <IMAGE></p> |
