Abstract: A thermal management system is provided that includes a cold-head cryocooler and a cooling jacket. The cold-head cryocooler is configured to be operably coupled to a helium vessel of an MRI system, and is configured to cool at least one of superconducting magnets or a thermal shield of the MRI system. The cooling jacket has an outer surface defining a sleeve exterior, and includes a pathway disposed radially internally of the sleeve exterior defined by the cooling jacket. The cooling jacket is configured to receive boil-off gas from the helium vessel to be circulated through the pathway to cool the cold-head cryocooler.

Abstract: A superconducting magnet cooling system is disclosed. The superconducting magnet cooling system includes a superconducting magnet; a liquid cryogen vessel for cooling the superconducting magnet; a heat exchanger device in fluid communication with the liquid cryogen vessel; a cryorefrigerator for heat exchange with the heat exchanger device; and a flexible connection device having high thermal conductivity and thermally connecting the cryorefrigerator and the heat exchanger device to provide vibration isolation of the cryorefrigerator from the heat exchange device.
