Description
Technical field
The present invention relates to a kind of heat pipe manufacturing system, particularly relate to a kind of flat plate heat tube manufacturing system of utilizing sucker to keep airtight and capping.
Background technology
Heat pipe is the splendid heat conducting element of usefulness in the present 3C electronic product, is used in the thermal source that is difficult for installing large-scale radiating fin usually.The for example microprocessor of mobile computer, holder for TV playing main frame, or host computer communication.The effect of heat pipe promptly is that the heat that above-mentioned thermal source is produced conducts to the radiator that is provided with radiating fin.Heat pipe is not only with low cost, and because heat pipe is to belong to passive heat dissipation element, so the work period decades-long of heat pipe.Different with copper or aluminium matter heat conducting element in the past is that the thermal conductivity factor of heat pipe is not a fixed constant.Along with the extension of heat pipe length to length, its thermal conductivity factor is bigger on the contrary.In addition, with the heat pipe of present industry made, its thermal conductivity factor is about tens of times to tens thousand of times of copper thermal conductivity factor.
As shown in Figure 1, general flat plate heat tube 1 comprises a hollow packaging body 11, and is located at the capillary structure 12 of described packaging body 11 inner surfaces, and is placed in the working fluid 13 in the described packaging body 11.Described packaging body 11 has an opposite heat absorbing end 111 and a radiating end 112, and the pressure in the described packaging body 11 are the saturated vapour pressure of described working fluid 13 self, and promptly described working fluid 13 is the stable equilibrium's attitudes that often are in liquid, gaseous state coexistence.In addition, described capillary structure 12 has most pores 121 that soaked into by described working fluid 13.
Be heated and when slightly heating up, destroy stable equilibrium's attitude of contiguous described heat absorbing end 111 working fluids 13 when described heat absorbing end 111, make liquid working fluid 13 evaporations of contiguous described heat absorbing end 111.At this moment, the vapour pressure of described heat absorbing end 111 makes a large amount of gaseous working fluids 13 flow to described radiating end 112 by described heat absorbing end 111 greater than the vapour pressure of described radiating end 112.Because the temperature of described radiating end 112 is lower, the gaseous working fluid 13 of contiguous described radiating end 112 is condensed, excessive liquid working fluid 13 also flows to described heat absorbing end 111 along described pore 121, and this promptly finishes one heat conducted to heat conduction cycle of described radiating end 112 by described heat absorbing end 111.
Owing to the described heat conduction cycle is to borrow stable equilibrium's attitude of destroying described working fluid 13 to produce, so even the temperature difference of described packaging body 11 2 ends is little, the described heat conduction cycle still can continue circulation constantly, and conducts a large amount of heat energy.
Though the not so difficult understanding of the operation principle of heat pipe, anyone all can draw materials from hardware shop and make the heat pipe of short-run voluntarily, in fact aspect the use of industry, it is high and heat pipe can long-term work is non-easy to make reliability.Early stage heat control technology for making is not reached ripe, and not only manufacturing speed is slow, and quality of finished is uneven.Reason is that in the past the heat pipe finished product very easily produces the defective that naked eyes can't be distinguished in manufacture process, though the good heat pipe of outward appearance and general quality is the same, but uses down that the vacuum of described heat pipe still can wreck for a long time.Keeping the vacuum in the described packaging body 11 promptly is the key that whether can be performed in the aforementioned heat conduction cycle.When described packaging body 11 outer surfaces had any destruction, described packaging body 11 inside and outside pressure differentials very easily made outside air penetrate into, and influence the equilibrium state in the packaging body 11, and therefore most of heat pipes all day by day lose original effect along with the time.
As shown in Figure 3, the existing system that makes described flat plate heat tube 1 comprise auxiliary filling degasification in the manufacture process steel pipe 14, one in order to fixing described packaging body 11 seize facility 15 on both sides by the arms, and cut off facility 17 and weld seam facility 18 in order to clamping facility 16, that seal respectively.Described clamping facility 16 and the described facility 17 of cutting off all are made up of carbon steel that can anti-high pressure, and the two is all metal current and processes the common facility of industry.18 on described weld seam facility can be a weldering Gun, also are facility commonly used in the present manufacturing industry.
Below promptly existing method, the cooperation facility of making described flat plate heat tube 1 are described, reach the origin cause of formation that vacuum wrecks with Fig. 2.
Cooperate shown in Fig. 1,3, step 192 is to form one at flat hollow packaging body 11 sides to be communicated with inside and outside through hole 113.Described packaging body 11 is to utilize the ductility material to form, and described packaging body 11 inner surfaces also are provided with a capillary structure 12, and described packaging body 11 and described capillary structure 12 all are made up of the good material of thermal conductivity.In addition, the mode that described capillary structure 12 can impress directly is formed at described packaging body 11 inner surfaces, the also independent wire netting of making.The mode that forms described through hole 113 can be when making described packaging body 11 and reserves groove opposite up and down at side, also can be described packaging body 11 is finished after additional processing and holes.No matter yet be to reserve groove or additional processing, need borrow all that described to seize seizing on both sides by the arms of facility 15 on both sides by the arms auxiliary, and because described packaging body 11 is very little, therefore describedly seize the integrality that facility 15 very easily destroy described packaging body 11 on both sides by the arms.When integrality that described packaging body 11 can't keep having, promptly be very easy to the vacuum in the described packaging body 11 of influence, and influence the quality of finished product.
In the step 193, make described steel pipe 14 be engaged to described through hole 113.In order to cooperate following steps, the joint of described steel pipe 14 and through hole 113 must keep enough air tightnesses.Yet joint methods such as welding commonly used in fact at present or gummed, the small pore that air tightness very likely occurs influencing in operation.
For the described heat conduction cycle can be performed smoothly, the optimum working pressure in the described packaging body 11 should remain on the vapour pressure of described working fluid 13, just makes described working fluid 13 be stable equilibrium's attitude.Therefore, promptly be to carry out the degasification operation in following step 195, get rid of described working fluid 13 gas in addition of gaseous state.As long as the vapour pressure that generally makes described packaging body 11 interior pressure equal described working fluid 13 can confirm to get rid of fully described working fluid 13 gas in addition.
Cooperate shown in Fig. 4,5, step 196 is to make described steel pipe 14 mouths of pipe of described clamping facility 16 clampings, and step 197 is to make the described facility 17 of cutting off cut off the flat envelope mouth end 141 that produces through step 196.So far, described packaging body 11 (see figure 3)s are complete closed, yet, before continuing next step, air tightness in described packaging body 11 (see figure 3)s relies on the packing between the described envelope mouth end 141 2 side thin plates fully, to reach temporary transient airtight effect, therefore after described clamping facility 16 discharge described envelope mouth end 141, still have the phenomenon of gas leakage.
Therefore, in the end a step 198 promptly is to make described weld seam facility 18 carry out spot welding at the envelope mouth end face 142 of described envelope mouth end 141, could reach fully and seal airtight effect.
Cooperate and consult Fig. 3, it should be noted that herein, for guaranteeing the airtight of when carrying out step 196 described packaging body 11 to step 198, so the clamping in the above-mentioned steps, cut off, and the spot welding action all must once finish, just described clamping facility 16, cut off facility 17, and described weld seam facility 18 must be located on the board altogether, not only make the facility cost higher, and power consumption is bigger, so the utmost point does not meet cost benefit.
By said process as can be known, the flow process of making flat plate heat tube 1 in the past is not desirable to the greatest extent, not only can't guarantee quality during the course, and the execution meeting of most steps destroys the integrality of described packaging body 11 indirectly, and the service life and the task performance of reduction flat plate heat tube 1, and manufacture process is extremely uneconomical.

Shown in Fig. 6,11, utilize the flow sequence and the existing flow sequence (see figure 2) of heat pipe manufacturing system manufacturing flat plate heat tube of the present invention similar, only the method for carrying out is slightly different.
In step 807, comply with aforementioned described sucker 61 and described first, second loading element 71,72 surface outside described packaging body 3 of being provided with respectively, simultaneously slightly clamp down on described sucker 61 and the described first loading element 71, make described sorption ring edge 613 must adhere well to described first surface 31 by described first pressure cylinder 731.
As Fig. 6,7 and shown in Figure 12, in step 809, see through the pressure in described vacuum extractor 63 described degasification filling pipes 62 of reduction and the described cavity 33,, can keep airtight with the characteristic that described first surface 311 fits tightly by described sucker 61 simultaneously to get rid of the gas in the described cavity 33.
As Fig. 6,8 and shown in Figure 13, step 811 promptly is 651,652 to 200 ℃ of described first, second heat-conducting pieces of heating, and increase the time that described working fluid 5 rests on described first, second heat-conducting piece 651,652 with described vaporization runner 653, described working fluid 5 is flowed through be gasified totally behind the described vaporization runner 653.Then in step 813, inject described working fluid 5 via described pod apertures 655, and the working fluid 5 that makes gasification because of pressure differential enters described cavity 33, and because described packaging body 3 temperature are far below first, second heat-conducting piece 651,652, the working fluid 5 that therefore enters described cavity 33 and be gaseous state promptly condenses and is attached to described pore 41.
As Figure 13,14 and shown in Figure 15,5 charging quantities of working fluid described in the step 813 are to control by described metering units 642, described metering units 642 comprises that a cylinder body 645, uprightly is inserted in the plunger 646 of described cylinder body 645 movably, and a location aware device 647 of being located at described plunger 646.Described location aware device 647 is a pressure perceptron in this preferred embodiment, and when exerted pressure by external force, described location aware device 647 promptly sends signal.Utilize the mode of described metering units 642 control charging quantities to comprise the following steps:
Step 90-sets described location aware device 647 in a primary importance 648.Described primary importance 648 repeats after holding with the relation of described working fluid 5 charging quantities.
Step 91-closes first valve 643 of described device for filling 64, and opens described second valve 644.
Step 92-drives described plunger 646, drive source can be air pressure, oil pressure or peristaltic pump or any power source, described plunger 646 is moved towards a second place 649 by described primary importance 648, and along with the moving of described plunger 646, described working fluid 5 is fills up to described cylinder body 645 from described storage tank 641.
When step 93-sends signal when described location aware device 647, stop to drive described plunger 646.When arriving at the described second place 649, described location aware device 647 is resisted against described support 22, and exerted pressure by described support 22 and send signal.Distance between the described primary importance 648 and the described second place 649 is bigger, the amount that then described working fluid 5 is fills up to described cylinder body 645 the more, on the contrary, distance between the described primary importance 648 and the described second place 649 is littler, and the amount that then described working fluid 5 is fills up to described cylinder body 645 is fewer.
Step 94-closes described second valve 644, and open described first valve 643, the step of start simultaneously 95-drives described plunger 646, described plunger 646 is moved towards described primary importance 648 by the described second place 649, and moving along with described plunger 646, described working fluid 5 is fills up to described packaging body 3 (see figure 8)s from described cylinder body 645, and at this moment, the amount that working fluid described in the step 92 5 is fills up to described cylinder body 645 is the actual charging quantity of described working fluid 5.
It should be noted that, 642 of above-mentioned described metering units are to provide a kind of simple and easy and charging quantity can stablize the filling method of control, because step 809 has made packaging body 3 form negative pressure state, therefore after first valve 643 is opened, workflow is known from experience naturally and can be moved toward packaging body 3, easily make metering units 642 produce bubble, yet when requiring precisely to control described working fluid 5 charging quantities and not producing the situation of bubble, described metering units 642 can utilize pressure cylinder to remain under the situation of high pressure, when opening first valve 643, because can impelling pressure cylinder drive plunger to move, pressure differential make working fluid be fills up to packaging body 3 naturally, again because the strength of negative pressure is less for the strength of pressure cylinder, can avoid when plunger arrives primary importance 648, closing first valve simultaneously because of negative pressure produces the aeration charging quantity.
In addition, the purpose of vaporization working fluid 5 is to get rid of when described working fluid 5 accumulations are attached to pipeline, the actual working fluid 5 charging quantity deficiencies that are fills up to described cavity 33, or pile up when being attached to from nearly described opening 32 when the working fluid 5 that enters described cavity 33, cause the problems such as flow process interruption of the described working fluid 5 of filling.Yet can understand just as being familiar with described skill personage, when the thickness of described packaging body 3 is big (for example its thickness is 8mm), foregoing problems can't produce, at this moment, also can get rid of described vapourizing unit 65 (see figure 8) and steps 811, and the direct liquid working fluid 5 of filling in step 813.
Shown in Fig. 6,18, utilize the operation of bearing down on one that cooperatively interacts between described first, second loading element 71,72 in the step 815.The so-called herein operation of bearing down on one refers to, and at normal temperatures, pushes with impressed pressure along the vertical surface direction, makes stock produce plastic deformation and does not rupture, and embodiment is implemented can know in the explanation of aspects following three and presented in detail.It is to possess under the state of aforementioned air tightness that aspect is implemented in first of the operation of bearing down on one, use described first, second pressure cylinder 731,732 (see figure 8)s drive described first respectively, the second loading element 72 is contiguous mutually, and by described Actuator Division 711 and the described packaging body 3 of described protuberance 721 extruding, making described packaging body 3 be positioned at described first surface 31 is out of shape with the part generation of second surface relative position about in the of 34, described Actuator Division 711 makes the zone that cover covers described opening 32 produce downward and inside crimp, 721 of described protuberances with the part of second surface 34 corresponding described openings 32 positions up jack-up form bulging deformations, and with the part collocation first surface 31 that protrudes towards the extruding of described opening 32 centers downwards and inside distortion be able to seal really described opening 32.
As shown in figure 16, it also is to possess under the state of aforementioned air tightness that aspect is implemented in second of the operation of bearing down on one, difference is in only using described first pressure cylinder, 731 (see figure 8)s to drive the described first loading element 71 and moves towards the described second loading element 72, and under the support of the described second loading element 72, by the described packaging body 3 of described Actuator Division 711 extruding, the part that makes described packaging body 3 be positioned at described first surface 31 is badly deformed, and pushes extension to seal described opening 32 towards described opening 32 centers.Therefore be noted that owing to the 72 not starts of the described second loading element also can get rid of described protuberance 721 in this enforcement aspect.In addition, the effect purpose of reaching this enforcement aspect only drives the first loading element 71 and exerts oneself, and pressure is also less, so this enforcement aspect is fit to the packaging body 3 of thinner thickness.
As shown in figure 17, it is to possess under the state of aforementioned air tightness equally that aspect is implemented in the 3rd of the operation of bearing down on one, difference is in only using described second pressure cylinder, 732 (see figure 8)s to drive the described second loading element 72 and moves towards the described first loading element 71, and under the support of described Actuator Division 711, by the described packaging body 3 of described protuberance 721 extruding, the part that makes second surface 34 be positioned at described first surface 31 relative positions is badly deformed, and pushes extension to seal described opening 32 towards described opening 32 centers.In addition, the effect purpose of reaching this enforcement aspect only drives the second loading element 72 and exerts oneself, because the protruding point unit are is little, institute's applied pressure is bigger, so this enforcement aspect is fit to the thicker packaging body 3 of thickness.
