The utility model has the advantages of high heat-transfer efficiency, simple structure, etc.

Description

Rotary target device of liquid metal cooling
The utility model relates to the rotary target device of a kind of liquid metal cooling, is used for the high heat load target assembly on all kinds of accelerators, especially for high-throughout neutron generator or be used for sealing neutron tube, belongs to the nuclear physics technical field.
The rotary target that uses on the accelerator all has a dynamic rotating mechanism to make the target body that is under the vacuum state be subjected to the moving and rotation of piebald horses such as motor beyond the vacuum and the purpose of cooling target body is derived and reached to the heat that utilizes heat transfer medium produced by high-energy particle bombardment target body.Concrete structure as shown in Figure 1, wherein 1 is flexible pipe, the 2nd, rotary seal, the 3rd, target body, the 4th, water collector, the 5th, cooling water, the 6th, target, the 7th, recirculated water, the 8th, driving key, the 9th, metering hole.The prior art weak point is: the transmission that 1) rotatablely moves must have a dynamic sealing means that connects vacuum system, can only apply to often have the dynamical system of vacuum pump exhaust, and can not be used for the static vacuum system of similar vacuum tube, therefore limited the range of application of whirligig.2) heat transfer relies on liquid circulation, and its heat transfer efficiency is lower, and the apparatus structure complexity.
The purpose of this utility model is a kind of novel rotary target device of design.Target body adopts the liquid metal under the normal temperature to do to support, lubricate and heat-conducting medium, and the dynamic rotary sealing appts in the cancellation prior art with simplification device mechanism, improves heat transfer efficiency.
Content of the present utility model is: the rotary target device of liquid metal cooling is made up of with permanent magnet and rotating driver target chamber, liquid metal thin slice, coolant guide pipe, coupling.The target sheet is floating to be held in the palm on thin layers of liquid metal, and thin metal layer contacts with a target chamber ancient piece of jade, round, flat and with a hole in its centre.Because liquid metal and target sheet and target chamber ancient piece of jade, round, flat and with a hole in its centre contact-making surface place form very strong molecular force, so no matter the target sheet is in vertically, level all can operate as normal down to being inverted suspension status.The opposite side of target sheet is a permanent magnet, and the permanent magnet on this permanent magnet and the target chamber inner rotary driving shaft is coupled, and drives the rotation of target sheet.Coolant guide pipe places outside the target chamber, and the thin layers of liquid metal between target and target chamber is gone out the heat transferred that produces on the target, by the recirculated cooling water that target chamber is outer heat is taken away.
Description of drawings:
Fig. 1 is the prior art structural representation.
Fig. 2 is the utility model structural representation.
Below in conjunction with accompanying drawing, introduce content of the present utility model in detail.Among Fig. 2, the 10th, target sheet, the 11st, thin layers of liquid metal, the 12nd, permanent magnet, the 13rd, rotating driveshaft, the 14th, coolant guide pipe, the 15th, ring flange, the 16th, light hurdle sheet, the 17th, target chamber.Ring flange 15 is to be used to connect the accelerator body among Fig. 2.High energy ion beam produces a large amount of heat energy along diagram direction of arrow bombardment rotary target 10.Target 10 is the average rate rotation by the driving that is positioned at vacuum chamber 17 rotary power square in addition under the support of liquid metal 11.So constantly change position that target surface is subjected to ion beam bombardment and can improve the transmission effect of heat greatly, the bombardment of line is left in the target surface that is heated rotation, and the liquid metal by contact conducts to target chamber 17 with heat and is recycled cooling water 14 at last and takes away simultaneously.So just reach the purpose of cooled target.The generation of target 10 turning moments and space coupling can have multiple scheme, wherein the simplest a kind of be exactly magnetic coupling mode between as shown in Figure 2 the permanent magnet: rotating driveshaft 13 useable electric moters drive and produce turning moment, are fixed with the permanent magnet 12 of coupling usefulness in the end of axle.Thereby its magnetic line of force acts on mutually by the wall of vacuum chamber 17 and permanent magnet 12 on being fixed in target 10 and drives its rotation and drive target 10 generations and rotatablely move when permanent magnet 12 rotation.Light hurdle sheet 16 is the positions that are used to limit the ion beam bombardment target surface, and the aperture can be regulated.
