Liquid cooling system for electromagnetic coil

Abstract

The invention discloses a liquid cooling system for an electromagnetic coil. The liquid cooling system comprises a liquid storage tank for containing an external insulating coolant, the electromagnetic coil which is located in the liquid storage tank and used for being immersed into the external insulating coolant, a hydraulic pump, a first pipe and a second pipe, wherein a channel is arranged inthe electromagnetic coil; a liquid inlet end of the hydraulic pump communicates with one end of the first pipe and the other end of the first pipe communicates with one end of the channel; the other end of the channel communicates with one end of the second pipe and the other end of the second pipe communicates with a liquid outlet end of the hydraulic pump; the channel of the electromagnetic coil, the hydraulic pump, the first pipe and the second pipe form a circulation loop; and an internal insulating coolant flows in the circulation loop. According to the liquid cooling system, the coolingeffect on the electromagnetic coil can be greatly improved.

Description

technical field [0001] The invention relates to the field of electromagnetic coil liquid cooling, in particular to an electromagnetic coil liquid 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, m...

[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 immersed in a tank filled with insulating coolant for cooling, but the cooling effect is poor, so it is far from meeting the needs of the industry.
