Description
Affiliated technical field
What the present invention relates to is the non-induction heating and the current driving device in controlled magnetic confinement thermonuclear fusion field, specifically is exactly a kind of many knots waveguide array antenna unit made by composite material of LOWER HYBRID CURRENT DRIVE antenna and water cooling plate that is mated use of being used for.
Background technology
The lower hybrid wave drive current experimental results show that to be the most effective non-induction drive current method on the controlled magnetic confinement thermonuclear fusion device of tokamak type, and the antenna great majority that use in the large-scale lower hybrid wave system are phased many knot waveguide array antennas.The microwave transmission theory shows: 1), microwave is by equal length, but during the rectangular waveguide of different broadside sizes, its phase change amount difference; 2), in rectangular waveguide, propagate TE
10During ripple, introduce the number of metal plate parallel with the waveguide broadside (E face knot) main waveguide is divided into the plurality of sub waveguide, can not destroy original field shape and distribute, that transmission also was TE during promptly each wavelet was led
10Ripple, and the wave phase that transmits in phase place and the main waveguide is identical.Phased many knot waveguide battle arrays are according to above principle design, be designed to 90 ° as adjacent wavelet being led a phase difference, then four sub-waveguides have just constituted a complete phase shift cycle, and several such cellular constructions combine, and just can constitute the waveguide array antenna of knot more than.
Choosing of waveguide array antenna material, must take into account the requirement of two aspects simultaneously: the one, excellent conducting performance is to reduce ohmic loss; The 2nd, excellent mechanical intensity is to guarantee the structural strength and the stability of antenna array.Choosing of waveguide battle array material, usually use now dispersion-strengthened Cu, or the special alloy material of other high strength, high conductivity, these materials are very expensive often, and the antenna manufacturing cost can be in any more.
Because it is limited making the conductivity of electrolyte materials of many knot waveguide battle arrays, so, when in the waveguide battle array, passing through microwave energy, the ohmic loss of material just can produce heat, along with microwave power strengthens, and the test duration lengthening, the heat that ohmic loss produces just can constantly be accumulated, and causes the temperature of waveguide battle array sharply to rise.When temperature rose to a certain degree, the mechanical strength of material will descend, thereby had influence on the antenna array stability of structure.Therefore, be equipped with suitable cooling device must for the waveguide battle array, what adopt usually in the world all is to use water-cooled mode.Waveguide battle array and water-cooling apparatus are integrally welded, have just constituted an antenna element or entire antenna.In existing in the world many knot waveguide array antennas, the cooled plate device is normally on a thicker corrosion resistant plate, along the antenna array longitudinal direction, dig some tubular conduits, water flowing in passage, like this, the heat that produces in the waveguide battle array, pass on the cooling water plate by heat conduction, take away by the current in the passage again, thereby reach the purpose of heat radiation.But the cooling effectiveness of such cooling water plate is very low, in order to guarantee enough heat dissipation capacities, just must thicken cooling water plate, to obtain enough bigbore cooling-water duct.Regrettably, the cooled plate thickening, the eddy current on it will increase thereupon.Eddy current increases, and can cause more thermal losses on the one hand, and on the other hand, eddy current can produce very large distortion moment in the powerful magnetic field of tokamak, influence the stability of antenna, makes the assembly structure of antenna become complicated.
Summary of the invention
The present invention is in order to address the above problem, the many knots waveguide array antenna unit that a kind of low cost is provided, makes with composite material, and the cooling water plate made from composite material that is used for this antenna element that greatly improves than prior art of a kind of cooling effectiveness.
The technical scheme that the present invention takes is: a kind of many knots waveguide array antenna unit made from composite material, comprise a waveguide array element and two cooling water plates, described waveguide array element as a wholely constitutes by eight sub-waveguides are side by side fixing along narrow limit, be separately installed with a cooling water plate on two narrow limits of this waveguide array element, it is characterized in that the Narrow Wall of Waveguide wall material that described wavelet is led selects oxygen-free copper for use, wide wall material then select for use " oxygen-free copper/stainless steel/oxygen-free copper " (TU1/SS/TU1) three layers of explosive clad plate make.
Because waveguide a period of time Narrow Wall of Waveguide wall material selects oxygen-free copper for use, wide wall material is selected " oxygen-free copper/stainless steel/oxygen-free copper " for use, and (TU1/SS/TU1), oxygen-free copper is led inner-wall material as wavelet, has guaranteed the favorable conductive characteristic, the ohmic loss when having reduced logical ripple.And wide wall material selects for use the advantage of " oxygen-free copper/stainless steel/oxygen-free copper " three layers of explosive clad plate to be: corrosion resistant plate is clipped in the middle of the two-layer no-oxygen copper plate, guaranteed the integral rigidity of composite plate, make antenna array have good mechanical stability, because the skin effect of microwave, this stainless steel interlayer can not produce any influence to microwave transmission.
A kind of water cooling plate made from composite material that is used for described many knot waveguide array antennas unit, comprise that one or more is along waveguide battle array longitudinal direction groove that distributes and the metal cover board that is used for closed groove, what it is characterized in that the tank of described water cooling plate selects for use is " stainless steel/oxygen-free copper " two-layer compound panel material, be provided with metal corrugated plate in the groove, this metal corrugated plate and groove, cover plate are fixedly connected as an integral body.
When cooling water flowed in groove, the corrugated plating in the groove can play turbulent flow and strengthen the double effects of area of dissipation, has greatly improved cooling effectiveness.Form three parts-grooves, corrugated plating and cover plates of cooling water plate, be linked to be an integral body by methods such as welding, thereby the intensity of this coldplate is strengthened, improved the compression resistance ability.Because this two aspect just can reduce the thickness of this cooling water plate greatly, thereby reduce issuable eddy current on it.And because the cooling water plate tank selects for use is " stainless steel/oxygen-free copper " two-layer compound panel material, the narrow wall of waveguide battle array that its no-oxygen copper plate basic unit and oxygen-free copper are made is connected to each other, because the plasticity of oxygen-free copper is strong, make that the applying of the two is very tight, further strengthened the heat-conductive characteristic between the two.
Beneficial effect of the present invention is as follows:
1), because the present invention adopts oxygen-free copper and stainless steel explosive clad plate material to replace general high strength such as dispersion-strengthened Cu, high conductivity special material, reduced the cost of antenna significantly.
2), the cooling effectiveness of cooling water plate used in the present invention increases substantially, under same heat radiation required, the thickness of cooling water plate is attenuate significantly, thereby has reduced issuable eddy current on the cooling water plate, has simplified the structure of entire antenna.
