Problems solved by technology

However, bellows are not resistant to high pressures, so only low pressure coolants can be used to cool superconducting magnets
Therefore, existing superconducting magnet cooling systems limit the cooling of superconducting magnets to low-pressure coolant

Abstract

The invention discloses a superconducting magnet cooling system comprising a superconducting magnet, a liquid coolant container used for cooling the liquid coolant, a heat exchanger unit fluid-connected with the liquid coolant container, a low temperature refrigerating machine carrying out heat exchange with the heat exchanger, and a flexible connecting device; the flexible connecting device has high thermal conductivity, and is in hot link with the low temperature refrigerating machine and heat exchanger unit, thus providing vibration isolation between the low temperature refrigerating machine and the heat exchanger unit, so the vibrations of the low temperature refrigerating machine cannot be transferred onto the superconducting magnet.

Description

technical field [0001] The present invention relates generally to magnetic resonance imaging (MRI) systems, and more particularly to a superconducting magnet cooling system. Background technique [0002] It is known that a superconducting magnet can become superconducting by placing it in an extremely cold environment, such as when it is enclosed in a cryostat or pressure vessel containing liquid helium or other liquid coolant. . Cryogenic refrigerators are widely used to maintain low temperature environments. Cryogenic cooling ensures that the magnet coils remain superconducting so that current flows through the magnet coils as soon as power is connected (for example, for a period of 10 seconds), even after power is removed, since there is no resistance in the coils. So the current will continue to flow through the coil, thereby maintaining a strong magnetic field. Superconducting magnet cooling systems are widely used in the field of MRI. [0003] However, when the cry...
