Abstract
An assembly has a two-stage cryogenic refrigerator and an associated mounting arrangement, and a sock having first and second stages corresponding to first and second stages of the refrigerator, with the first stage of the refrigerator being in thermal contact with the first stage of the sock and the second stage of the refrigerator being in thermal contact with the second stage of the sock.
Claims23
An assembly comprising a two-stage cryogenic refrigerator (17) and associated mounting arrangement,
- comprising a sock (15) having first (61) and second (68) stages corresponding to first (30) and second (32) stages of the refrigerator (17),
- wherein the first stage of the refrigerator is in thermal contact with the first stage of the sock and the second stage of the refrigerator is in thermal contact with the second stage of the sock,
- characterised in that one or more fasteners (40) are provided, within a section of the sock, said section extending between the first stage of the sock and the second stage of the sock,
- said fastener(s) acting on the second stage of the refrigerator and the second stage of the sock to mechanically clamp the second stage of the refrigerator into contact with the second stage of the sock. (FIGS. 8, 12)
An assembly according to any preceding claim, wherein a bracing piece (36) is provided, attached to the second stage (32) of the refrigerator, the fasteners (40) acting on the bracing piece to press the second stage of the refrigerator into contact with the second stage of the sock.
An assembly according to any preceding claim, wherein mechanical tie rods (60) brace first stage (61) of the sock against a second stage retaining structure (63) to mechanically restrain the second stage of the sock against the first stage of the sock.
An assembly according to any preceding claim, wherein the sock (15) is provided with an upper interface piece (64).
An assembly comprising a two-stage cryogenic refrigerator (17) and associated mounting arrangement,
- comprising a sock (15) having first stage (152) corresponding to a first stage (122) of the refrigerator (17) and a closed end,
- wherein the first stage of the refrigerator is in thermal contact with the first stage of the sock and a second stage (124) of the refrigerator is in thermal contact with a heat exchanger (130) provided within the sock, between the first stage of the sock and the closed end of the sock,
- characterised in that one or more fasteners (138) are provided,
- within the section of the sock extending between the first stage of the sock and the closed end of the sock, said fastener(s) acting on the second stage of the refrigerator and the heat exchanger to mechanically clamp the second stage of the refrigerator into contact with the heat exchanger. (FIGS. 9, 10)
An assembly comprising a two-stage cryogenic refrigerator (17) and associated mounting arrangement,
- comprising a sock (15) having first (152) and second (154) stages corresponding to first (122) and second (124) stages of the refrigerator (17),
- wherein the first stage of the refrigerator is in thermal contact with the first stage of the sock and the second stage of the refrigerator is in thermal contact with the second stage of the sock,
- characterised in that one or more fasteners (138) are provided,
- traversing the second stage (154) of the sock, to act on the second stage of the refrigerator and the second stage of the sock to mechanically clamp the second stage of the refrigerator into contact with the second stage of the sock. (FIG. 11)
