Abstract

The invention provides an electric insulation cold conduction structure which comprises a first metal piece, a second metal piece, a pre-tightening assembly, an insulation assembly and an insulation cold conduction sheet distributed between the first metal piece and the second metal piece, and at least one of the first metal piece and the second metal piece is electrified. One of the first metal piece and the second metal piece is used for being connected with a refrigerating machine. The pre-tightening assembly enables the first metal piece, the insulation cold conduction sheet and the second metal piece to be tightly pressed. The insulation assembly enables the first metal piece and the second metal piece to be insulated. One of the first metal piece and the second metal piece, which is connected with the refrigerator, cools the other metal piece through the very thin insulating cold conduction sheet, so that cold conduction is realized, and insulation is achieved through the insulation cold conduction sheet and the insulation assembly. Thus, good cold conduction efficiency is guaranteed, the cold conduction path and the conductive path are not subjected to electric leakage, and finally good insulation between the first metal piece and the second metal piece and temperature difference as small as possible are guaranteed.

Description

technical field [0001] The invention relates to the technical field of application of superconducting magnets, in particular to an electrically insulating and cold-conducting structure. Background technique [0002] Magnetic resonance imaging (MRI) uses the magnetic resonance phenomenon of atomic nuclei (such as protons) under a highly uniform magnetic field to image different tissues and organs in the human body, thereby realizing medical diagnosis and other functions. At the end of 1978, the first magnetic resonance system was born in a log cabin at the Siemens research base in Erlangen, Germany. In late 1979, when the system finally worked, its first work was an image of a chili pepper. In March 1980, the first human brain image was obtained, and the data collection time at that time was 8 minutes. In 1983, Siemens successfully installed the first clinical magnetic resonance imaging equipment at the Hannover Medical School in Germany. The magnetic field strength of this...
