Title:
PARAFFIN WAX SOLID-ENCAPSULATION FURNACE FOR VEHICLE-MOUNTED SUPERCONDUCTING MAGNET COIL
Document Type and Number:
WIPO Patent Application WO/2024/051669
Kind Code:
A1
Abstract:
A paraffin wax solid-encapsulation furnace for a vehicle-mounted superconducting magnet coil. Compared with existing paraffin wax solid-encapsulation furnaces, the paraffin wax solid-encapsulation furnace for a vehicle-mounted superconducting magnet coil combines a paraffin wax melting compartment and a solid encapsulation compartment as a whole, and thus has a compact structure. Arranging a paraffin wax tank (9) inside the solid-encapsulation furnace can eliminate an original paraffin wax pipeline that is exposed to the environment, and can thus prevent paraffin wax from undergoing cooling, solidification, blockage and ejection from a paraffin wax injection port due to the paraffin wax flowing in the pipeline, thereby making a pouring process smooth and controllable and achieving a good solid encapsulation effect. In terms of temperature control, heat is transferred mainly in an air convection manner, and electric heating tubes (12, 13, 15) and a turbulent fan (11) are scientifically arranged, which effectively eliminates the internal temperature gradients of a coil and the paraffin wax and improves the uniformity of temperature distribution thereof. In terms of pouring control, a vibration exciter (17) arranged below a superconducting coil tray (10) can effectively accelerate the discharge of bubbles from the coil. In terms of vacuum control, only a slight negative pressure in the furnace needs to be maintained, such that the requirements for the performance of a vacuum pump (4) and the sealing of a furnace body (1) are all greatly reduced, and the manufacturing difficulty and cost are relatively low.
