Description
Technical field
The present invention relates to hall thruster ceramic heat-dissipating field.
Background technology
Hall thruster is current widely used electric propulsion device, compares with traditional chemical propulsion plant, has efficiency
Height, than the advantage leapt high and the life-span is long etc..Its operation principle is: there is mutually orthogonal radial direction in hall thruster passage
Magnetic field and axial electric field, from emission of cathode to passage in the electronics effect by magnetic field and electric field under drift about to anode, with from
The Working medium gas of gas distributor ejection collides ionization, and the electronics ionized out is little due to quality, is constrained in by radial magnetic field
In passage, and mass of ion is big, and magnetic field is substantially inoperative to it, and the effect in axial electric field power accelerates spray to channel outlet
Go out, thus produce thrust.
Hall thruster origin of heat in the course of the work is mainly made up of two parts, and a part is that ion is in electric field force effect
Lower to outlet accelerated motion during, do not spray outside passage, but be splashed on wall, ion energy is converted into heat；
Another part is that electronics is drifted about to anode by the effect in electric field and magnetic field, the heat that electronics produces with anode compound tense.
This two parts heat makes the wall surface temperature of pottery passage higher, simultaneously carries out conduction of heat and hot spoke to magnetic circuit and coil
Penetrate, cause the temperature drift of magnetic circuit and coil, coil temperature higher can accelerating coil insulated hull aging even burn out show
As, magnetic circuit temperature drift can make pcrmeability decline rapidly, and both common effects can change magnetic field bit-type and the magnetic of thruster
Field intensity, and then reduce performance and the job stability of thruster.
Summary of the invention
The present invention is to solve existing hall thruster poor radiation, reduces performance and the job stability of thruster, this
Bright provide a kind of hall thruster ceramic heat-dissipating support.
A kind of hall thruster ceramic heat-dissipating support, it includes drum-shaped structure, and the upper port of drum-shaped structure is provided with outer convex edge,
The bucket inner bottom surface of drum-shaped structure is provided with an inner sleeve, and inner sleeve is coaxial with drum-shaped structure, and inner sleeve runs through
The bottom surface of drum-shaped structure,
The height of inner sleeve is less than the height of drum-shaped structure,
Multiple circle or rectangle engraved structure it is uniformly provided with along the circumferencial direction of drum-shaped structure bucket wall.
This cooling stand uses copper to realize.
The outside wall surface of described drum-shaped structure carries out process of spraying paint.
Described outer convex edge is being provided with 4 installation through holes along the circumferencial direction of drum-shaped structure uniformly.
In the course of the work, the compound meeting of the bombardment of ion pair wall and electronics and anode causes pottery passage to hall thruster
The deposition of interior amount of heat so that the temperature drift of pottery passage, this partial heat passes through heat radiation by the heat in vias inner walls face
Amount is delivered on coil, transfers heat on outer magnetic pole and base plate by conduction of heat so that the temperature of magnetic structure raises,
And then the pcrmeability of reduction magnetic circuit, the most magnetically saturated state, the serious performance reducing thruster, coil temperature simultaneously
In the highest service life that can reduce insulated hull, even burn out.Therefore, the present invention is delayed by conduction of heat and heat radiation two ways
With the thermal environment of pottery passage, improve thruster performance and job stability.
The present invention brings and provides the benefit that, by using the ceramic heat-dissipating support of hollow out, has not only acted as installation pottery passage
Effect so that pottery passage outer surface directly radiates to spatial environments, and cooling stand selects the high material of heat conductivity simultaneously
And carry out surface reason, increase the heat-sinking capability of pottery passage, reduce cooling stand and the contact area of outer magnetic pole as far as possible,
Reduce pottery passage to transmit to the heat of coil and magnetic circuit, thus play a protective role, reduce coil and the temperature of magnetic circuit, carry
The life-span of high thruster and job stability.
