Abstract
The invention discloses an antenna protection limiter, which comprises a heat sink main body of the protection limiter, cooling channels, a bus joint, a first wall tile, a coupling screw and a fixing mechanism. The antenna protection limiter has a simple structure, effectively eliminates the influence of the protection limiter on antenna coupling, and prevents an antenna from directly bearing high-energy particle bombardment. A plurality of water cooling channels are integrated on the same heat sink main body, and complex water-cooling pipeline connection is avoided. Therefore, compared with the prior art, the heat sink structure is greatly simplified, and the cooling efficiency is greatly improved.
Description
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 a kind of plasma limiter that is used to protect the lower hybrid wave antenna.
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 antenna is that direct microwave energy is coupled to the visual plant of plasma.Because lower hybrid wave launching antenna will be directly towards high-temperature plasma, so antenna must bear thermal radiation and high-energy particle bombardment from plasma, for the protection lower hybrid wave launching antenna, need dispose special protection limiter for it.
The protection limiter places end in face of the aerial radiation, and is the same with antenna, and the heat load of protection limiter is mainly from the radiant heat of Tokamak Plasma.Can think approx that plasma equals to come from total heating power of tokamak outside approx to the inner gross power that discharges of tokamak; according to parameters such as the capture area of protecting limiter and tokamak first wall total surface areas, the plasma resonance that can calculate the absorption of protection limiter is to its surperficial heat energy.
Under long pulse high parameter plasma service conditions; the radiant heat that the protection limiter absorbs is quite high, therefore needs the very high radiator structure of design cooling effectiveness, what is more important; limiter must make antenna not be subjected to high-energy particle bombardment under the situation that does not influence the lower hybrid wave launching antenna coupling.In the world, the cooling of protection limiter all is the method that adopts Forced water cooling.
Summary of the invention
The invention provides a kind of antenna protection limiter of compact conformation, solved the limiter cooling effectively, do not influence the antenna coupling and avoided antenna directly to bear the key issue of high-energy particle bombardment.The present invention greatly simplifies on mechanical structure than the lower hybrid wave protection limiter that each big tokamak device in the world now adopts, and it is also more convenient to install.
The technical scheme that the present invention takes is:
A kind of antenna protection limiter; include tokamak device first wall tile; heat sink main body; it is characterized in that: described first wall tile bends to curved sections; it is the deep-slotted chip breaker of wedge shape that the curved interior direction of described first wall tile has cross section; fit in the described deep-slotted chip breaker heat sink main body that cross section is a wedge shape is installed; on having, the heat sink main body two ends turn over bending section; some water cooling passageways are arranged in the described heat sink main body; heat sink end is equipped with external fixation bindiny mechanism and advances; the water outlet joint that confluxes describedly advances; water outlet conflux joint respectively with the water inlet end of water cooling passageway; the water side connects.
Described antenna protection limiter is characterized in that: fixedly connected with described first wall tile by screw in the bottom of described heat sink main body.
Described antenna protection limiter; it is characterized in that: the water inlet end of some water cooling passageways in the described heat sink main body pools together and is connected with the water inlet joint that confluxes, and the water side of some the water cooling passageways that heat sink main body is interior pools together and is connected with the water outlet joint that confluxes.
It is that material is made straight protection limiter heat sink main body that the present invention adopts metallic copper, chooses suitable heat sink size, directly bears the bombardment of high energy particle to avoid antenna; On heat sink main body, adopt some water cooling passageways that connect fully of deep hole drill gun processes; By precision form equipment straight heat sink main body is bent to the outer contour shape structure similar with the Tokamak Plasma boundary shape; Adopt vacuum brazing technique, several water cooling passageways are pooled to minority turnover connecting interface, be connected with extraneous water-cooling system with convenient by the joint that confluxes; On accurate digital control equipment, heat sink main body is processed into specific wedge-type shape, to eliminate of the influence of protection limiter to the antenna coupling; With the special-purpose material tile of the first wall of shape and limiter coupling, by screw on heat sink main body.
Beneficial effect of the present invention:
1), the present invention adopts deep hole drill gun technology, vacuum brazing technique and the joint that confluxes, the multiple tracks water cooling passageway is integrated on the heat sink main body, avoided numerous and diverse water-cooled pipeline to connect, made heat sink structure be simplified significantly than prior art, cooling effectiveness is greatly improved.
2), the designed heat sink profile of protection limiter of the present invention is specific curve form, eliminated the influence of protection limiter to the antenna coupling effectively, the bombardment of having avoided antenna directly to bear high energy particle.
3), the present invention design ingenious rationally, simple in structure, the integrated level height, with low cost, be beneficial to popularization.
