Description
Technical field
The present invention relates to a kind of liquid filling device, more particularly, but the present invention relates to a kind of filling apparatus of quantitative filling liquid.
Background technology
About the working medium can of heat pipe, the methods for filling of working medium in several heat pipes below having introduced in the document " Ma Tongze, Hou Zengqi, Wu Wen Guang, heat pipe, Science Press, ISBN 7-03-002011-1,1991,277-282 ":
(1) filling of sodium heat pipe introduced the distillation sodium refilling system;
(2) filling of hydro-thermal pipe comprises the boiling method that vacuumizes the can method and need not vacuumize;
(3) filling of controlled heat pipe mainly is amount how to control unreactable gas;
(4) cryogenic heat pipe fills.
But these four kinds of methods for filling all belong to the category at big heat pipe, and they are suitable for charging into the more situation of amount of working medium, and relative error is less, but are subjected to methods for filling and the restriction that fills instrument, and absolute error is still bigger.If absolute error is had the occasion that fills of requirement, these methods just are difficult to finish filling of little absolute error.
At present, the microminiaturization degree of heat pipe improves constantly, because the internal capacity of microminiature heat pipe is less, the amount of the working medium that need charge into is also smaller, therefore, if adopt above-mentioned four kinds of methods, the relative error that then charges into working medium can be very big, and the amount that charges into working medium is difficult to accuracy control.The performance of microminiature heat pipe quality has much relations with the levels of precision of working medium filling weight, and for the microminiature heat pipe, what the existing conventional charging system can not satisfy a little working medium accurately fills requirement.
Document " G.P.Peterson, An Introduction to Heat Pipes, A Wiley-Interscience Publication, John Wiley ﹠amp; Sons, Inc., ISBN 0471-30512-X, 1994,202-205,256-259 " and " A.Fahgri, Heat Pipe Science and Technology, Taylor ﹠amp; Francis Inc., ISBN 1-56032-383-3,1995,664-670 " in the methods for filling of two kinds of microminiature heat pipes proposed:
(5) the overcritical method that fills.The microminiature heat pipe is put into high-pressure-resistant vessel, after high-pressure-resistant vessel is vacuumized, earlier it is added a certain amount of liquid refrigerant, then high-pressure-resistant vessel is heated to more than the transformation point of working medium, i.e. supercriticality.Under this state, all working medium all exists with the form of steam, so working medium can be uniformly distributed in the space in high-pressure-resistant vessel and the heat pipe, and opposite heat tube adopts ion or ultraviolet ray to be bonded and sealed then.After opening high-pressure-resistant vessel, cooling is condensed working medium.By controlling volume, the pressure in the container and vacuumizing the amount of the working medium of adding afterwards, the amount that charges into working medium in the opposite heat tube can accuracy control.
(6) vertical imbibition priting.End sealing with micro heat pipe vertically places in the vacuum chamber.The non-tight end of microminiature heat pipe is from the about 1mm of topping up bottom land.Vacuum chamber is vacuumized, with a microsyringe a small amount of liquid refrigerant is slowly injected the topping up groove, pressure in the vacuum chamber raises, up to approaching near the time with the corresponding saturated pressure of vacuum chamber, working medium forms a liquid pool in the topping up groove, sucked by the conduit of micro heat pipe, seal conduit effectively, seal the liquid in the heat pipe and the steam on top.Take out micro heat pipe, open end is sealed.Staying the amount of working medium in the heat pipe can be controlled from the distance of topping up trench bottom and the liquid measure that is expelled in the vacuum chamber by the temperature, the heat pipe that change heat pipe before the sealing.
(5) though plant the methods for filling of micro heat pipe to reach filling weight accurate, but sealing at present can only be at silicon chip, sealing for metal microminiature heat pipe is difficult more, and generally needs pressure container and the attached heating control system that helps, and also has far distance from practical application.(6) methods for filling of planting micro heat pipe has comprised the method for operation of a lot of experiences, and commonality and accuracy rate also are more difficult to get assurance.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
As shown in Figure 1, the base portion of filling apparatus of the present invention is a cylinder body 1, comprises the first piston chamber 31 and second plunger shaft 32 in the cylinder body 1, and the top of cylinder body 1 is provided with a cap chamber 4, is used to be communicated with the first piston chamber 31 and second plunger shaft 32.The top in first piston chamber 31 is provided with a perforate, extends a liquid outlet channel 2 by this perforate to cylinder body 1 outside.Piston with its sealing contact, i.e. a first piston 51 and second piston 52 are arranged respectively in two plunger shaft.The bottom of piston is connected with the connecting rod of a rigidity, with first piston 51 bonded assemblys are first connecting rods 61, with second piston, 52 bonded assemblys are second connecting rods 62.The bottom that these two connecting rods pass cylinder body enters in the exterior slideway 9 of cylinder body, and connecting rod can vertically move in slideway 9.First connecting rod 61 is connected with an interlinked mechanism with second connecting rod 62, and the function of this interlinked mechanism is drive link, make with connecting rod bonded assembly piston up and down two different directions move simultaneously.For example in the present embodiment, this interlinked mechanism should make first piston 51 upward movements and second piston 52 is moved downward.
This device has been full of the liquid that needs can in cap chamber 4, first piston chamber 31 and second plunger shaft 32 when carrying out can work.Interlinked mechanism makes the first piston 51 and second piston 52 move simultaneously, makes the cumulative volume of cap chamber 4, first piston chamber 31 and second plunger shaft 32 diminish, and liquid is extruded by unique liquid outlet channel 2 in cylinder body 1, realizes the can of liquid.In order to determine the liquid measure of filling liquid, this interlinked mechanism also should comprise the measuring cell that is used for measuring indirectly the liquid liquid measure.
In mechanical field, interlinked mechanism and the measuring cell of realizing such function have different ways, for example in the present embodiment, this interlinked mechanism is preferably realized as follows: referring to Fig. 1, at first connecting rod 61 and second connecting rod 62 first tooth bar 71 and second tooth bar 72 are set respectively, these two tooth bars are parallel with connecting rod.Gear 8 is coupled between two tooth bars and with tooth bar.When gear 8 clockwise rotates, by the rack drives connecting rod, make first piston 51 upward movements, second piston 52 moves downward simultaneously.For the angle that prototype gear 8 rotates, can use a marking panel (not shown) that has angle index, this marking panel and gear 8 coaxial settings like this, just can read the rotational angle of gear 8 easily.
Gear 8 optional single speed gears or preferred two-speed gear.The single speed gear is usually said single gear, and two-speed gear refers to two different gears of the coaxial radius that is fixed together.
When gear 8 was the single speed gear, the area of the first piston 51 of upward movement was greater than the area of second piston 52 that moves downward, and the movement rate of these two pistons is identical.When two pistons move under the drive of gear 8 simultaneously, the liquid in the cylinder body 1 will be extruded from liquid outlet channel 2 like this.The area S of first piston 51
1, second piston 52 area S
2And the radius r of single speed gear can be selected according to the precision of liquid volume measurement.When gear 8 rotates the θ radian, from the liquid liquid measure V=r θ (S of liquid outlet channel 2 extrusion
1-S
2), and r (S
1-S
2) value more little, the angle θ that the single speed gear rotates is big more, the measuring accuracy that can realize is also high more.In table 1, provided four groups of concrete examples, as follows:
Table 1
| Filling amount V (ml) | θ (radian) | ????r ??(cm) | ????S 1??(cm 2) | ????S 2????(cm 2) | ????r(S 1-S 2) ????(cm 3) |

| ????6.2832 | ????2π | ????1 | ????10 | ????9 | ????1 |
| ????0.7854 | ????π/4 | ????1 | ????10 | ????9 | ????1 |
From top example as can be seen, using a design problem of single speed gear is to require under the situation of higher measuring accuracy, then requires the area difference needs of the first piston 51 and second piston 52 very little, perhaps requires the radius of gear 8 very little.In order to address this problem the gear 8 preferred two-speed gears that use.Two gears that constitute two-speed gear respectively with first tooth bar 71 and 72 engagements of second tooth bar, with the radius of first tooth bar, 71 gears in meshs be r
1, with the radius of second tooth bar, 72 gears in meshs be r
2By the rotation of two-speed gear, drive first piston 51 upward movements and second piston 52 moves downward.The area S of first piston 51
1, second piston 52 area S
2And the radius r of two-speed gear

2) value more little, the angle that two-speed gear rotates is big more, the measuring accuracy that can realize is also high more.Than the single speed gear, adopt the advantage of two-speed gear to be: (1) can be at S
