Abstract
The invention relates to heat sink of electromagnetic coil operated under high current load. The coil is placed inside immersion oil sheath with high temperature insulation oil being filled in. the inner wall of the immersion oil sheath is prepared from non - magnetic conductivity material, and outer wall and up / down planes are prepared from ferromagnetic material. Being setup outside the immersion oil sheath, cooling jacket includes inner wall prepared from non - magnetic conductivity material, and up / down planes prepared from ferromagnetic material. High temperature insulation oil possesses much better heat-conducting property than the property of air so as to quicken speed of heat elimination for electromagnetic coil immersed in high temperature insulation oil, and increase working current of oil, and driving power. The cooling jacket strengthens heat exchange, and increases driving power further. Thus, coil can work under high current load.
Description
Technical field
The present invention relates to a kind of heat abstractor of solenoid, particularly a kind of heat abstractor that is operated in the solenoid under the high current load state belongs to reactor engineering and correlation engineering technical field thereof.
Background technology
Electromagnet is when energising work, and its solenoid can generate heat.Present existing solenoid all is mounted in the air dielectric, and heat all distributes by air.But after the drive current load strengthened, caloric value also can increase thereupon, and the heat of coil inside is difficult to distribute, thereby formed the overheated of part.This problem has limited the increase of work of electromagnet load.For example in reactor magnet control rod drive mechanism, the coil cooling system that adopts just carries out in the outside of solenoid housing at present, can't be deep into the inside of coil.When drive current load increases, will cause the over-heat inside of coil, thereby make the mechanism can't operate as normal.
Summary of the invention
The heat abstractor that the purpose of this invention is to provide a kind of solenoid when being operated in the high current load state to solve solenoid, causes coil inside local overheating problem.
Technical scheme of the present invention is as follows:
A kind of solenoid heat abstractor contains solenoid, it is characterized in that: this heat abstractor also comprises the immersion oil cover of a sealing, fills with high-temperature insulation oil in the cavity of immersion oil cover, and described solenoid is placed in the immersion oil cover; The inwall of immersion oil cover is a non-magnet material, and outer wall and last bottom surface are ferromagnetic material, adopts between the internal face of immersion oil cover and outside wall surface and the last bottom surface to be tightly connected.
Another technical scheme of the present invention is:
A kind of solenoid heat abstractor, contain solenoid, it is characterized in that: this heat abstractor also comprises the immersion oil cover of a sealing and is arranged on the outside coolant jacket of immersion oil cover that fill with high-temperature insulation oil in the cavity of described immersion oil cover, described solenoid is placed in the immersion oil cover; The immersion oil cover adopts non-magnet material to make, and the inwall of coolant jacket is a non-magnet material, and outer wall and last bottom surface are ferromagnetic material; Be provided with coolant inlet and coolant outlet on coolant jacket, the inwall of coolant jacket and outer wall and last bottom surface adopt and are tightly connected.The immersion oil cover
In the such scheme of the present invention, described high-temperature insulation oil is high temperature transformer oil or silicone oil.
High-temperature insulation oil of the present invention adopts high temperature transformer oil or silicone oil.
The present invention compared with prior art, have the following advantages and the high-lighting effect: the present invention is immersed solenoid in the high-temperature insulation oil, by the high-temperature insulation oil more much better than air heat conductivility, the heat of coil inside is taken out of, accelerate the radiating rate of whole winding, thereby increase the operating current of coil, improve driving force; In addition in order further to improve the driving force of electromagnet, the present invention also in the outer setting of immersion oil cover coolant jacket, thereby further strengthened heat exchange, therefore, solenoid is worked under bigger current capacity state.
