Description

Heat Pipe Capillary Organizations Sintering Method And Its Device

Technical field

The present invention relates to a kind of Heat Pipe Capillary Organizations Sintering Method And Its Device, relate in particular to a kind of sintering equipment that utilizes a heat pipe sintering to make, cooperate sintering manufacturing process, making has the heat pipe of equal thickness capillary structure, to improve the yields of making, reduce cost, obtain preferable gas phase and change and heat transference efficiency.

Background technology

Known heat pipe capillary structure sintering preparation method and device, as shown in Figure 1 and Figure 2, the copper pipe 1 that mainly utilizes an end to seal is the heat pipe body.Openend suit funnel 11 at copper pipe 1; Openend with axle 12 insertion copper pipes 1 utilizes the gap that is used for sintering capillary structure 10 13 that forms between the inwall of axle 12 and copper pipe 1, will be made the copper powders may of capillary structure 10 by funnel 11 and pour gap 13 into; Pass through sintering process then, make copper powders may be combined in copper pipe 1 internal face; As shown in Figure 2, extract axle 12 out and promptly form the heat pipe that hollow and wall have capillary structure 10, as shown in Figure 3.But in above-mentioned known heat pipe capillary structure sintering manufacturing process, the diameter of axle 12 must be less than copper pipe 1 internal diameter with funnel 11, could and copper pipe 1 between form gap 13.But there is the diameter difference and the technological means or the concrete structure of any mutual location are not set again at the copper pipe 1 of axle 12 and its insertion and 11 in funnel, make axle 12 can't remain on the middle position of copper pipe 1, therefore, will inevitably produce the deflection of an angle, make the copper powders may of pouring in the gap 13 can't obtain homogeneous thickness, as shown in Figure 2, make capillary structure 10 that sintering is formed in copper pipe 1 inwall also be the shape of equal thickness not.Therefore, when the heat pipe of making was used in the heat transmission, the gas phase that the capillary structure 10 of inhomogeneous uniform thickness will directly influence in the heat pipe changed, and also directly influences heat transference efficiency and effect.

The specific embodiment

Relevant technology contents of the present invention and detailed description, existing conjunction with figs. is described as follows:

Fig. 4, Fig. 5 are the structure chart of the heat pipe capillary structure sintering equipment of one embodiment of the present invention.This sintering equipment comprises: make heat pipe body 2, be used to the fill tool 4 that inserts the body of rod 3 of body 2 and have first anchor point, as shown in Figure 4.

Body 2 is an elongated pipe that includes hollow bulb, and body 2 has openend 21 and extends and unsealed draw end 22 at the other end.The diameter of draw end 22 is less than body 2 diameters.Thus, utilize that draw end 22 forms that end to the body of rod 3 plays the role of positioning second anchor point.

The body of rod 3 is one can insert the rectangular body of rod of the hollow bulb of body 2, and the diameter of the body of rod 3 is less than the internal diameter of body 2.When the body of rod 3 inserts bodys 2 and during through first and second anchor point location, between the external diameter of the body of rod 3 and body 2 inwalls, form an equidistant gap 5, adhere to for capillary structure 6 fillings and sintering.The body of rod 3 forms gradually-reducing shape bar head 31 endways, is used for when the body of rod 3 inserts body 2, and gradually-reducing shape bar head 31 can be inserted in the draw end 22, forms second anchor point.

Fill tool 4 is funnel in the present embodiment, and the sleeve pipe 41 of its extension is used to be sleeved on outside the openend 21 of body 2, by its leak capillary structure 6 is filled in the body 2.Fill tool 4 further includes the location division 42 that is positioned at by the space of group that hopper walls 40 encloses, and is formed on first positioning function of fill tool 4 and the body of rod 3 one ends.Location division 42 is positioned at fill tool 4, the leak central authorities concentric position place of sleeve pipe 41, and have the internal diameter identical with the external diameter of the body of rod 3.Thus, can be at the hollow bulb that inserts body 2 and by draw end 22 second anchor point the body of rod 3 with the fill tool 4 corresponding other ends, form first anchor point by 42 location, location division.

Location division 42 in the fill tool 4 can be directly and hopper walls 40 one-body molded rib arms, extend and be the fixed folder fixation kit of pulling, or utilize a plurality of adjustment assemblies 43, as screw assembly etc., extend composition to the center, play folder effect of pulling and position corrective action (as Fig. 4, shown in Figure 5), thus form adjustable be used to press from both sides the folder of the body of rod 3 fixation kit of pulling of pulling.

Fig. 4 to Fig. 7 is the making flow process of the heat pipe capillary structure sintering method of one embodiment of the present invention.Heat pipe capillary structure sintering method of the present invention wherein, is sleeved on fill tool 4 openend 21 of body 2; Then, with the hollow bulb of the body of rod 3 insertion bodys 2, and by draw end 22 insertions of its tapered rod head 31 facing to body 2, to obtain the positioning function of second anchor point; Seal draw end 22 simultaneously, the capillary structure 6 of filling in follow-up manufacturing process can not spilt; The body of rod 3 extends an end of fill tool 4, then contacts with the location division 42 of fill tool 4 and obtains first anchor point.Thus, utilize this first and second anchor point that the body of rod 3 is positioned at body 2 hollow bulbs, and with the equidistant gap 5 that body 2 inwalls produce the concentric circles state, be used to fill capillary structure 6 (as Fig. 4, shown in Figure 5).Then;

Utilize the leak of fill tool 4 to guide capillary structure 6, be fills up to equidistant gap 5 (as shown in Figure 6), send into sintering furnace then and carry out sintering manufacturing process.After sintering is finished, take out cooling, the capillary structure 6 of hot melt solidified attached to body 2 internal faces, again with the body of rod 3 by extracting out in the body 2, promptly finish the heat pipe finished product that inwall has equal thickness capillary structure 6, as shown in Figure 7.

The above only is the preferred embodiments of the present invention, be not so promptly limit claim of the present invention, the equivalent structure transformation that every utilization specification of the present invention and accompanying drawing content are done, or directly or indirectly be used in other relevant technical field, all in like manner be included in the claim of the present invention.
