Abstract

A thermosiphon cooling system is presented. One embodiment of the thermosiphon cooling system includes a reservoir having a first portion configured to store a liquid coolant. The thermosiphon cooling system also includes a tubing unit coupled to the reservoir and disposed adjacent to at least one superconducting unit to be cooled and configured to receive the liquid coolant from the first portion of the reservoir, and circulate the received liquid coolant within the tubing unit to dissipate heat generated by the at least one superconducting unit. The received liquid coolant is circulated within the tubing unit by varying a density of the received liquid coolant at different portions of the tubing unit.

Description

Background technique [0001] This disclosure relates generally to magnetic resonance imaging (MRI) systems, and more particularly to thermosiphon cooling systems and methods for cooling superconducting magnets in MRI systems. [0002] Superconducting magnets are used to generate magnetic fields in MRI systems. In some methods, a current from a power source is constantly applied to a superconducting magnet to generate a magnetic field. However, generating such a strong magnetic field requires a constant supply of current in the range of hundreds of amperes. This constant supply of current to the superconducting magnet increases the operating costs of the MRI system. [0003] Also, in some other techniques, superconducting magnets may be subjected to different thermal loads in the MRI system. It is desirable to divert these thermal loads away from the superconducting unit in order to maintain the superconducting magnet at a cryogenic temperature and to operate the superconduct...
