Abstract
The present invention relates to a round end type closing method of heat-conducting pipe. Said method includes the following main measures: firstly, making the closing end of heat-conducting pipe into the form of neck ring, and utilizing the portion of upper pipe of said neck ring form tightly be connected with pipe component of vacuum pump, vacuum-pumping, press-closing and cutting, then welding and sealing said cut conical end.
Description
Technical field
The present invention is a kind of heat pipe construction that applies to the auxiliary heat dissipation of computer internal unit or electronic equipment heat abstractor, refers to the mouth-sealing method of a kind of two ends person for cone shape thermal conducting pipe round end type especially.
Background technology
Press, be used for various electronic equipments at present, or computer equipment, as the heat radiation of the central processing unit (CPU) of computer inside, the pattern of its radiator is quite a lot of, and some equipment needs the radiating effect of height again under limited space, as laptop computer equipment etc., for this reason; Heat pipe is that the heat energy that will remove earlier guides rapidly, and a kind of auxiliary radiating device that is dispelled the heat in position, and only how heat pipe is installed on the utilization of radiator, and non-pass emphasis of the present invention holds and do not give unnecessary details.
Please referring to shown in Figure 1, general thermal conductance heat pipe is to be made of the hollow metal tubing 11 of an elongated and inwall with metal particle 12, and its length is the structure that cooperates radiator, cuts off into suitable length and assembles utilization.And for example shown in Figure 2, for will improving heat-conducting effect, need the inside 13 of hollow metal tubing 11 is added an amount of a kind of auxiliary conductive fluid that be applicable to each temperature layer, the state that is evacuated again, and with the openend sealing of this metal tube, block and scolding tin.
There are various sealing modes the termination of heat pipe in the market, and accepted practice has: directly concora crush is cut off the reducing concora crush scolding tin type of scolding tin type etc.And for example: novel " heat pipe enclosuring structure " patent case that No. the 431617th, the Taiwan patent announcement etc. several; Wherein:
Novel " heat pipe enclosuring structure " patent case as No. the 431617th, Taiwan patent announcement, be to be pressed into U type shape after hollow metal pipe is vacuumized, and in U type envelope pressure side position lining one deck soldering-tin layer, again U type envelope pressure side biside plate is bent and swings into round shape again towards the U type mouth of central authorities in opposite directions, though this practice is on enclosuring structure intensity and the comparable direct concora crush of density is cut off the scolding tin type and reducing concora crush scolding tin type is strong, but this sealing operation need repeatedly be carried out, time-consuming taking a lot of work, and hollow metal pipe is after vacuumizing, to be pressed into the operation of U type shape again, have under the atmospheric environment its operation have any problem.After and for example this heat pipe is finished, must be when the tin hot weld be on the structure of radiator, the misgivings that can cause former soldering-tin layer to come off because of the high temperature when the scolding tin.
Summary of the invention
The mouth-sealing method that the purpose of this invention is to provide a kind of thermal conducting pipe round end type, can guarantee that not only sealing of heat pipe is firm, can be on the structure of radiator when and for example needing with the tin hot weld, not only can increase useful life, more increase effective heat conduction length of heat pipe, and cone shape sealing end makes that the plug-in mounting operation is more convenient.
For achieving the above object, solution of the present invention is: a kind of mouth-sealing method of thermal conducting pipe round end type, it is in position to swing the neck ring shape littler than former caliber earlier at the caliber of heat pipe, inject auxiliary conductive fluid in the pipe, the last square tube position of neck ring shape is next to the pipe fitting of vacuum pumps, press off immediately behind the state of being evacuated and cut off, the awl end that will cut off is at last welded into coniform.
Be provided with the cutter of radian at the sealing end outer wall.And this sealing end gets to reserve earlier and welds material, and is closely pressed off to cut-out by cutter.
Install cooler additional at the heat pipe suitable position, be enough to do moment of weighing and weld the high temperature that is produced and get off to carry out sealing operation so that heat pipe is cooled in advance.
After adopting such scheme, the present invention can guarantee that not only sealing of heat pipe is firm, and for example need the time can with the tin hot weld on the structure of radiator, not only can increase useful life, more increase effective heat conduction length of heat pipe, and cone shape sealing end makes that the plug-in mounting operation is more convenient.

Embodiment
See also shown in Figure 3, the present invention in position swings the caliber of heat pipe sealing end than former caliber is littler earlier (to subsidize conductive fluid convenient the injection, and vacuumize in the scope of operation) neck shape shape sealing end 14, and after sealing end 14 forms tiny inlet 15 and injects an amount of subsidy conductive fluid, and utilize last square tube 16 positions of neck ring shape sealing end 14 to be connected to the pipe fitting of vacuum pumps closely.And then state as shown in Figure 4 is evacuated heat pipe, then at cutter 17 high-pressures of sealing end 14 outer walls to have radian, and this sealing end 14 gets to reserve earlier and welds material in order to sealing operation, closely press off immediately to cutting off 18 as Fig. 5, the awl end that will cut off is at last welded into coniform 20 as Fig. 7.So, can guarantee that not only sealing of heat pipe is firm, reach durability, and this heat pipe also can cooperate the demand of tin hot weld on the structure of radiator of must using, also contraction in length because of sealing, relative increase the effective length of heat pipe, and coniform 20 the operation of sealing when making on the structure be inserted into radiator is more convenient.For avoiding sealing the connecting airtight property of being heated in the Shi Yinguan and making institute's volume expansion gas break through bad sealing end, can install cooler 19 additional again, weld the high temperature that is produced and get off to carry out sealing operation heat pipe is cooled to the moment that is enough to contend with in advance at the heat pipe suitable position.
