Abstract
An arrangement for cryogenic cooling comprising a cryogen tank (14), a cryogenic recondensing refrigerator (12) arranged to cool a heat exchanger which is exposed to the interior of the cryogen tank (14) and an arrangement (16; 26) for conducting heat from a cooled article (10) to the cryogen tank. A further cryogen tank (20) is provided below the heat exchanger and arranged to receive cryogen liquid recondensed on the heat exchanger.
Claims14
A cryogenic cooling arrangement comprising:
- a cryogen tank (14);
- a heat exchanger exposed to an interior of the cryogen tank (14);
- a cryogenic recondensing refrigerator (12) in thermal contact with the heat exchanger (13) and
- an arrangement (16;
- 26) that conducts heat from a cooled article (10) to the cryogen tank,
- characterised in that the cryogenic cooling arrangement comprises a further cryogen tank (20) linked to the cryogen tank through a constriction, the further cryogen tank being fluidly connected to receive cryogen liquid recondensed on the heat exchanger, the further cryogen tank (20) housing components (21), whereby said components are cooled by cryogen liquid received in the further cryogen tank.
An arrangement according to any preceding claim wherein the arrangement that conducts heat comprises a solid thermal conductor (26).
An arrangement according to any preceding claim wherein the cooled article, the cryogen tank and the arrangement (16;
- 26) for conducting heat are housed within an outer vacuum container.
An arrangement according to any preceding claim wherein the cooled article (10) comprises a superconducting magnet coil.
An arrangement for cryogenic cooling substantially as described and/or as illustrated in FIGS. 2-9 of the appended drawings.
