Description

technical field [0001] The invention relates to the field of electromagnetic coil cooling, in particular to an electromagnetic coil cooling system. Background technique [0002] At present, the electromagnetic coil will generate a magnetic field when it is energized, and it will also generate heat while generating the magnetic field, especially when the electromagnetic coil is applied to a strong magnetic field repeating frequency magnet in the laser-driven proton medical range, a single energization load can Generate a strong magnetic field above 10T, but due to the existence of electromagnetic coil resistance, strong current and dense winding are required to generate a strong magnetic field, so the electromagnetic coil will also generate a large amount of Joule heat while generating a strong magnetic field. If the heat is not Discharging in time will increase the temperature of the coil and increase the resistance of the coil. When the next load is applied, more heat will ...

[0002] At present, the electromagnetic coil will generate a magnetic field when it is energized, and it will also generate heat while generating the magnetic field, especially when the electromagnetic coil is applied to a strong magnetic field repeating frequency magnet in the laser-driven proton medical range, a single energization load can Generate a strong magnetic field above 10T, but due to the existence of electromagnetic coil resistance, strong current and dense winding are required to generate a strong magnetic field, so the electromagnetic coil will also generate a large amount of Joule heat while generating a strong magnetic field. If the heat is not Timely discharge will increase the temperature of the coil and increase the resistance of the coil. When the next load is applied, more heat will be generated and the strength of the magnetic field will be reduced. Therefore, these heat must be discharged

At present, the electromagnetic coil is mainly cooled by immersing it in insulating cooling liquid, but the cooling effect is poor, so it is far from meeting the needs of the industry.
