Title:
CRYOGENIC LIQUID TRANSFER TUBE
Document Type and Number:
WIPO Patent Application WO/2016/129799
Kind Code:
A1
Abstract:
A cryogenic liquid transfer tube, according to the present invention, enables insulation of a tube, through which a cryogenic liquid is being transferred, by means of a plurality of insulating films which have a multi-layer film structure and of which each of the film layers is positioned away from each other at a fixed interval by means of step-shaped supports. Moreover, by having the plurality of insulating films surround the tube in multiple layers with the tube being the center and by having an inner insulating film and an outer insulating film disposed along the length direction of the tube so as to alternately offset each other, the transfer path of the heat being transferred from the outside into a transfer tube is extended to the maximum length, thereby enabling more effective insulation.
