FIELD: cryogenic engineering. SUBSTANCE: heat-reflecting screen consisting of herringbone-shaped members spaced from one another is mounted between cryoagent tube and casing. Every herringbone-shaped member has cooling agent tube in vertex of its corner and two recesses bent inwards on edges of one of herringbone-shaped flanges to provide for thrust onto flange (having no recesses) of adjacent herringbone-shaped member. In this case, every herringbone-shaped member is coupled to cryoagent tube and casing by means of paired supports. EFFECT: improved and simplified heat insulation. 1 dwg
