Abstract
The utility model relates to a sealing opening structure of a heat guide pipe. The utility model is a pipe body, wherein one end of the pipe body is provided with a conical sealing opening; a plurality of layers of welding spots are stacked at the point of the conical sealing opening; the welding spots and the conical sealing opening are coated in a plurality of layers of soldering tin layers by a plurality of layers of soldering tin layers. Consequently, when the pipe body is extruded in the process of downstream processing, or in the state which is caused by the heated pipe body that internal air pressure is increased, the point of the conical sealing opening can still maintain an intact condition without worrying about air leakage. Thus, when arranged inside a computer or in any applicable range, the heat guide pipe can exert the due heat radiating function thereof.
Description
Technical field
The enclosuring structure of a kind of heat pipe of the utility model provides a kind of particularly inner or any applicable scope of computer of being located at, and all can bring into play heat sinking function, has the heat pipe of complete closure layer in its sealing part.
Background technology
Because computer is in operation; its inner high power wafer regular meeting causes abnormal running because of fuel factor; damage because of overheated for fear of the high power wafer; the various dissimilar radiating subassemblies so can pack in computer inside; for example: radiator fan, radiating fin or heat pipe or the like, and wherein the quick conductive effect of heat pipe is gradually accepted for industry and is used.In addition, as the waste heat recovery of solar heat protection interference, the energy and the environmental project of auto industry, national defense applications with utilize or the like again, must rely on the high heat dissipation characteristics of heat pipe and reach.
Existing heat pipe please cooperate with reference to shown in Figure 8, is the body 20 of the metal of a hollow, and the one end is a blind end 21, in addition end be one have a solder joint 24 seal 23.
The method for making of existing heat pipe is, please cooperate with reference to shown in Figure 7, and behind a body 20 acquisition suitable lengths, through processing modes such as reducing and welding, blind end 21 is promptly finished with the one end.Finish the vacuum fluid injection again in inside, and vacuum fluid injection process is sealed into a U-shaped recess 22 with its openend in the mode of U-shaped riveted again for the conductive fluid of reinjecting after the body 20 inner formation vacuum.
Please cooperate again with reference to shown in Figure 7, the end that body 20 is had a U-shaped recess 22 after welding, form have a solder joint 24 seal 23.
Before reality is used; industry can be carried out explosion bulge test with the body 20 that has completed usually; so that the seal of test body 20; and so-called explosion bulge test is body 20 to be placed in the pot arch body is heated, and owing to liquid (conductive fluid) the Yin Wendu rising of body 20 inside is vaporized, as seals 23 and can't bear from body 29 pressure inside; will produce the phenomenon of gas leakage; so body 20 reliabilitys that the dealer produced are not good,, be a puzzlement greatly far and away for the dealer.
Summary of the invention
The utility model is because sealing when explosion is tested of existing heat pipe still can be sealed gas leak phenomenon, in order to stop the doubt of heat pipe gas leakage, special with this further improvement of sealing end structure do, can make the reliability of heat pipe better by this, reason air leakage failure and can't bring into play due heat sinking function not when using is its creation purpose.
In order to reach aforesaid creation purpose, technological means of the present utility model is: a kind of enclosuring structure of heat pipe, and the metal body with a hollow is characterized in that: the one end is a blind end, end seals less than the coniform of body for external diameter in addition, has the solder joint of stack at coniform sealing part.
When body carries out explosion experiment or actual the use, it is located at solder joint and soldering-tin layer that coniform sealing part is provided with multilayer (two layers or more), owing to seal and body fits tightly with coniform, so can keep coniform closure of sealing, make it can't produce the problem of rupture and leakage, so when body is installed in computer when inner or any applicable scope, the port air leakage failure that reason the is not possible and due heat sinking function of heat pipe can't be brought into play.

The specific embodiment
The enclosuring structure of a kind of heat pipe of the utility model, please cooperate with reference to figure 5 and shown in Figure 6, the body 10 of the metal of one hollow, the one end is a blind end 11, end seals 15 for external diameter less than the coniform of body 10 in addition, in the coniform folded several layers solder joint 14,16 that is provided with in 15 places that seals, and with several layers soldering-tin layer 17 with solder joint 14,16 and coniformly seal 15 and be coated in it.
Please cooperate with reference to shown in Figure 1, in a plurality of embodiment of the present utility model, one embodiment, when body 10 in the acquisition suitable length after, the one end is after processing modes such as reducing and spot welding or welding are handled, this processing mode can be reached easily for being familiar with this operator, so do not give unnecessary details, blind end 11 is promptly finished.After finishing the vacuum fluid injection in body 10 inside again, and vacuum fluid injection process is with the body 10 inner vacuum that form, and promptly finish behind filling heat-conductive liquid, and this process can be reached easily for those skilled in the art, so do not give unnecessary details, again openend sealed into a U-shaped recess 12 in the mode of U-shaped compacting riveted.
Please cooperate with reference to shown in Figure 2, an end that body 10 is had a U-shaped recess 12 seals 13 through what spot welding or the formation of welding back had a solder joint 14.
Please cooperate with reference to shown in Figure 3, because sealing 13 is that high temperature spot welding forms, phase I seals 13 solder joint 14 and easily forms an arc body 141 because of the hot polymerization effect, around the arc body 141 intensity a little less than, thereby may or transport collision or air pressure that internal liquid gasification produces causes little leakage phenomenon to take place because of machining deformation, so U-shaped recess 12 in the whirl round mode of (pressing circle) of bending riveted and folding, is formed an external diameter and seals 15 less than the approximate circle taper of body 10.
Please cooperate shown in Figure 4, coniform 15 places of sealing carry out spot welding for the third time or welding, make its solder joint with another layer 16, please cooperate again with reference to figure 5 and shown in Figure 6, what will have a solder joint 14,16 coniformly seals 15 and carries out the tin sticky processing procedure, be stained with one or more layers soldering-tin layer 17 so that body 10 is had coniform surface of sealing an end of 15, so finish the making of heat pipe.
So when industry after heat pipe completes, when carrying out explosion bulge test or during actual the use, because sealing 15, body 10 coniform be the multilayer enclosed construction, so even the inside of body 10 is formed with big pressure, or may produce collision when installing and using, coniform 15 the double-deck solder joint 14 of sealing, 16 still can keep coniform 15 the closure of sealing, so situation about can leak gas not, so work as heat pipe and be installed in computer inside, during equipment such as automobile or solar heat protection interference, heat pipe just can be stablized its due heat radiation function of performance, does not have the situation that lost efficacy because of gas leakage and produces.
