Abstract:
An apparatus for transferring cryogenic refrigeration includes a cryocooler interface, a housing, a working fluid, a heat exchanger, a flexible thermal link, and a remote cartridge cold head. The cryocooler interface is thermally connected to a cryocooler providing a source of refrigeration. The refrigeration is passed from the crycooler into the heat exchanger via the cryocooler interface. The remote cartridge cold head is attached to a remote location. Heat is drawn from the remote location through the remote cartridge cold head and into the heat exchanger via the working fluid within the flexible thermal link and housing. Within the heat exchanger, heat is transferred from the working fluid to the refrigeration source, such as a cryocooler; accordingly, the remote location is cooled.
Abstract:
A cooling system for superconductive magnets according to the present disclosure includes a vacuous container, a superconductive magnet forming a magnetic field, a superconductive magnet bobbin surrounding the superconductive magnet and made of thermally conductive material, a freezer for exchanging heat with the superconductive magnet bobbin to cool the superconductive magnet, a vibration-type heat pipe contacting the superconductive magnet bobbin to induce heat exchange with the freezer, and a radiation shield for blocking heat radiation introduced to the superconductive magnet. Therefore, it is possible to implement a stable cyrogenic cooling system, which may eliminate the generation of a temperature gradient between the freezer and the superconductive magnet so that the superconductive magnet may be efficiently cooled and may recover a superconducting status within a short time.
