A cooling device which is equipped for remote manipulation arm, the operation usefulness at high temperatures during the conflict medium

摘要

The remote handling device comprises a rigid segments (12, 14, 16) maintained at a temperature suitable for their operation by a device according to the invention. This latter comprises an enclosure (37, 38, 39), surrounding each rigid portion (12, 14, 16), connected to a source of the heat-exchanging gas high pressure. This enclosure comprises two chambers (92, 94), respectively at high and low pressure, connected together by means (102) of the expansion of the gas. The rigid segments (12, 14, 16) of the remote handling device are connected together by articulations surrounded by the bellows (40, 42). Each bellows is supplied by the heat-exchanging gas coming from the low-pressure chamber (94) of an enclosure (37, 38, 39) which is adjacent to the bellows. The gas flows in a closed circuit comprising the chambers (92, 94) and the bellows (40, 42), by absorbing the energy propagating through the remote handler. & br / application to an intervention in a reactor with a fast neutrons.
