Problems solved by technology

However, with existing cryostats carried in about 1750 liters of cryogen, the potential for cryogen loss is much greater
A much greater cost risk is associated with the possibility of vaporizing the entire volume of cryogen: the cryostat will vaporize to dryness and the cooled unit will be heated to ambient temperature, say 300K

Embodiment Construction

[0011] Current shipping methods include initially filling the cryostat with refrigerant to a level sufficient to maintain the operating temperature for 30 days. The present invention aims to lower this initial fill level sufficiently to maintain the operating temperature for a much shorter period of time, for example, three days. This should be sufficient to maintain the system at operating temperature during air transport to any part of the world. The volume of refrigerant liquid placed in the transport system can be reduced by up to 90%.

[0012] According to an aspect of the present invention, the cryostat containing the device to be cooled has means for active cooling during transport. The member is active during most or all of the transit time. When the cryostat is carried in certain modes of transportation (for example, air, rail, or sea), it may not be allowed to operate the active refrigeration component. For this reason, it is necessary to provide a sufficient volume of l...

Abstract

Apparatus for transporting cryogenically cooled goods or equipment (12), comprising a cryostat (10) containing the cryogenically cooled goods or equipment (12) and partially filled with liquid cryogen (11) is provided with a cryogenic refrigerator (14) for active cooling; and auxiliary equipment (22, 24, 26) sufficient to maintain the cryogenic refrigerator (14) in operation, are all mounted on a transportable carrier (40) such that the transportable carrier may be transported with the cryogenic refrigerator (14) in operation without connection of any of the cryostat (10), refrigerator (14) and auxiliary equipment (22, 24, 26) to any supplies located off of the transportable carrier (40). Also provided is a method for transporting such apparatus to a destination, with the cryogenic refrigerator (14) operating during transport.

Description

Technical field [0001] The present invention relates to a method and equipment for transporting cryogenically cooled goods or devices, such as those used in magnetic resonance imaging (MRI) or nuclear magnetic resonance (NMR) imaging systems. Superconducting magnet. In particular, the present invention relates to the method and apparatus for ensuring that the device is still cryogenically cooled when reaching its destination, in which the consumption of the refrigerant substance on the way is limited. Background technique [0002] When a cryogenic system, such as a superconducting magnet used in a magnetic resonance imaging (MRI) or nuclear magnetic resonance (NMR) imaging system, arrives at its installation site, its way of arrival should be such that it can be deployed as quickly as possible. The current method is to place the magnet in a refrigerant container filled with liquid refrigerant before starting the journey. In the case of low temperature superconductor (LTS), this l...
