Technical Field
The utility model relates to the technical field of deicing equipment, in particular to a deicing tool for MR equipment.
Background
The superconducting magnet on an MR apparatus generally consists of a superconducting coil and a cooling system, the superconducting magnet being a device that generates a magnetic field by conducting an electric current through a conductive material, the biggest feature of which is that below its critical temperature, the resistance will drop to zero and the current will flow without consumption. The superconducting material is immersed in liquid helium. The cooling system in the MR device mainly volatilizes liquid helium into helium and then turns the helium into liquid helium in a refrigerating mode, so that the process of liquid helium 0 loss is realized.
The liquid inlet of the current MR equipment is a pipeline through which the refrigerated liquid helium flows into the magnet, and because of the low-temperature environment, the pipeline of the liquid helium inlet is small, the liquid helium is impure, the container has poor tightness, and the internal pipeline of the liquid helium inlet of the magnet is possibly blocked by ice due to process defects and the like. Helium gas evaporated from liquid helium does not flow into the magnet due to liquid helium changed by cooling of the cooling system, thereby causing liquid helium loss. It is difficult for a conventional tube to be aligned with the inlet helium port for de-icing operations.
