The specific embodiment
Conventionally the heat pipe, for example, using at the hot-pipe type heat-exchanger in energy-conservation (waste heat recovery) field mainly comprises shell and fills the working media (also referred to as working medium) in shell.While manufacturing such heat pipe, mainly contain following operation: prepare as required shell, can directly purchase the shell of selling on market, or by machinings such as punching presses, process the shell of required form; Shell is carried out to pre-treatment, i.e. the cleaning such as degreasing and rust removal, and drying, so that fill while use after working media, avoids impurity or shell material etc. that working media and inner wall of tube shell adhere to react; The shell being disposed is filled to working media; Toast with exhaust having filled the shell after working media; To the working media injection port end socket welding of shell; Whether the heat pipe that inspection institute makes has the problems such as gas leakage, in the situation that being up to the standards, completes the manufacture of heat pipe.In addition, according to actual needs, end cap is also installed on shell sometimes, that is, above-mentioned fill working media before, be also included in the operation that end cap is installed on shell.
In above-mentioned manufacturing process, to shell fill working media exhaust, then by particularly important the operation of working media injection port end socket welding.This is because insufficient if working media fills, the heat transfer efficiency of heat pipe is low, heat conductivility deterioration.Even and if fill enough working medias, if exhaust is insufficient, may in shell, there is the impurity such as incoagulable gas, in the time that heat pipe is worked, this gas is purged to solidifying section of formation vent plug that gathers together of punching by vapor stream, thereby effective condensation area is reduced, and thermal resistance increases, heat conductivility worsens, and the capacity of heat transmission reduces even inefficacy.In addition, be the basic demand of heat pipe for the sealing of shell, but not only guaranteeing that prior art is still difficult to realize, and still has room for improvement to working media exhaust completely but also avoid exhaust exceedingly suitably by aspect the welding of working media injection port end socket.
Below, by reference to the accompanying drawings, the manufacture method of heat pipe of the present invention is described, that is, above-mentioned working media injection and deairing step and sealing process is mainly described.
Fig. 1～Fig. 5 is the sketch of the manufacture method of explanation heat pipe of the present invention.
Operation 1: with reference to Fig. 1, inject working media 2 to shifting to an earlier date ready shell 1.Described shell 1 is one end as the tubular container of injection end, other end sealing, comprises shell main body 1a and is communicated with shell main body 1a and from the 1b of ozzle portion of the protruding certain distance of injection end of shell main body 1a.The diameter of the 1b of ozzle portion is less than shell main body 1a, can be by the injection end part necking down of shell main body 1a is formed.
Injecting when working media, be connected with the linker 3 of pipe arrangement 4 in a side contrary with shell main body 1a of the 1b of ozzle portion, thereby the working media of ormal weight 2 is injected in shell main body 1a via pipe arrangement 4, linker 3, the 1b of ozzle portion.
About above-mentioned linker 3, as shown in Fig. 6 (a), can be the linker that No. 4309989 communique of Japan Patent recorded.It comprises: have Embedded Division 3a and the tubulose linker main body in upper end with the linking part 3b being connected with working media implantation tool (as pipe arrangement 4 etc.) for embedding the shell ozzle 1b of portion; For can with front end clamp shell the 1b of ozzle portion outer surface and can freely swing and be located at two clamping components 3c in linker main body; Chimeric and by the clamp structure 3d of tubular fastening clamping components 3c moving freely thereon along the length direction of linker main body.Between clamp structure 3d and the outer surface of linker main body, clip Compress Spring, by Compress Spring, clamp structure 3d has been suppressed to the direction of fastening clamp member 3c.And, be formed with the intercommunicating pore injecting for working media in the inside of linker 3.
Thus, as shown in Fig. 6 (b), when in the 1b of ozzle portion that the Embedded Division 3a of linker 3 is inserted to heat pipe package, the compressed spring of clamp structure 3d suppresses downwards, slide and press clamping components 3c along the outer surface of linker main body, clamping components 3c is held on the 1b of ozzle portion of heat pipe package securely thus.Thus, can with simple mechanism, linker be securely fixed on the outer surface of ozzle portion of shell, via the intercommunicating pore of linker 3 inside, can be reliably and inject working media or by discharges such as incoagulable gas without leaking.
In addition, about working media, be not particularly limited, can be according to suitably selecting with the operating temperature of the compatibility of used shell material, heat pipe, for example, high-temperature heat pipe can select potassium, naphthalene etc. as working media, and moderate temperature heat pipe can be selected methyl alcohol, propyl alcohol, water etc., and Cryo Heat Tube can be selected HFC-134a (HFC-134a), HFC-245fa (pentafluoropropane) etc.About the injection rate of working media, owing to adopting the mode that working media heating is made to its boiling and exhaust in the present invention, therefore consider discharge loss, preferably inject more more than actual requirement, for example actual requirement+(30 ± 5ml).
About the method for injecting working media, can be in advance shell to be vacuumized, utilize negative pressure that working media is injected to shell, also can not vacuumize, but working media is injected shell by direct weighting, as long as injecting the method for working media.
Operation 2: with reference to Fig. 2, working media inject stop after, under the state that linker 3 cuts out, utilize heater, burner etc. to heat the bottom of shell 1, make in shell main body in press liter.
In order to improve the intensification uniformity of working media, more than preferably heated perimeter (, the heating part of shell main body) spreads all over the working media liquid level in shell bottom.And, in this heating pressurization operation, according to the difference of working media, more than being preferably heated to injected working media boiling point under atmospheric pressure, thereby make gas contained in working media become bubble and working media is separated, and a part of working media form steam and upwards drive the air being originally present in shell out of.
Operation 3: with reference to Fig. 3, be respectively equipped with the first temperature sensor T1 for measuring heating part temperature on shell 1, be located at the second temperature sensor T2 between heating part and the injection end of shell main body 1a and be located near the three-temperature sensor T3 injection end of shell main body 1a.
Utilize the first temperature sensor T1 to measure the temperature of heating part, in the time detecting that T1 temperature is greater than boiling point under atmospheric pressure of working media, the linker short time is opened, the gas in shell main body 1a is emitted.
According to the kind difference of working media, linker is opened to the asynchronism(-nization) of exhaust, preferably 0.5～10 second, be more preferably 3～5 seconds, if evacuation time is long, can discharge too much working media, cause the waste of working media, if evacuation time is too short, exhaust deficiency, cause exhaust increased frequency, reduce operating efficiency.
After the evacuation time of short time, linker cuts out again to 3～7 minutes, interval, preferred interval 5 minutes, then reheat, repeat above-mentioned operation 2～operation 3, until the temperature that the temperature that the second temperature sensor T2 is measured to and three-temperature sensor T3 are measured to is roughly equal.At this, operation 2, operation 3 are collectively referred to as to exhaust gas purification operation, preferably, at interval of 5 minutes repeating this exhaust gas purification operation 2～10 times, more preferably repeat this exhaust gas purification operation 2～5 times.
In above-mentioned exhaust process, be positioned at inert gases such as the air of shell inside etc. and be discharged to shell outside, be full of shell inside by the liquid of working media and the steam of working media, cause evaporation, condensing in whole shell inside, upper and lower temperature difference diminishes.Therefore, as the second temperature sensor T2 between heating part and the injection end of shell main body 1a and be located at temperature that near the three-temperature sensor T3 injection end of shell main body 1a measures when roughly equal, while confirming in shell without temperature difference, can be judged as the incoagulable gas such as air are discharged completely, by working media, shell inside is full of.
In addition, in the time that whether incoagulable gas such as confirming air discharges completely, gas sensor also can be set near gas discharge outlet, the gas componant that judgement is discharged thus, in the time the working media gas of ormal weight being detected, be judged as shell inside and be full of by working media, stop exhaust gas purification operation.About described " ormal weight ", according to adopt working media and difference.In the situation that adopting HFC-134a, HFC-245fa as working media, because HFC-134a, HFC-245fa contact meeting generation corrosivity by force and poisonous gas with surface or the flame of high-temperature metal, no matter from environmental protection aspect or security aspect consider, it is all dangerous medium, therefore, preferably at gas discharge outlet, gas sensor and working media retracting device are set, avoid this working media gas to be directly released to outside, operator or environment are worked the mischief.
Operation 4: discharged completely after the incoagulable gas such as air in operation 3, as shown in Figure 4, linker 3 taken off make product in the situation that, mechanically the 1b of ozzle portion squeezed flat, so that gas can not circulate, then cut off squeezing between flat part and linker 3.
Operation 5: as shown in Figure 5, by the part sealing of cutting off, make thus the heat pipe that long-term reliability is high by welding.
In addition, also exist and do not need to take off the situation that linker directly uses, retain linker, a side contrary to shell of linker cut off and sealed.
As mentioned above, in heat pipe package, enclose working media, in shell, become by the liquid of working media, the steam of working media and the state being originally full of with regard to the air existing.Injecting the injection port of the working media device that is connected seals and becomes the state that working media can not be revealed to outside.Then utilize the heating part of the bottom of the opposite heat tube shells such as heater to heat, make the temperature of lower of heat pipe package become temperature more than working media boiling point under atmospheric pressure.Now, shell inside is due to the rising of the temperature of working media, and vapour pressure raises.The air originally just existing is shifted onto shell top on the steam of working media.In the moment that reaches temperature more than working media boiling point under atmospheric pressure, utilize the linker in the ozzle portion that is installed on heat pipe package that internal gas is emitted to outside, first superposed air is pushed out into outside.Thus, shell inside is almost full of by the liquid of working media and steam.
And contained dissolved gas in working media liquid because of the variation of the temperature and pressure of working media, becomes bubble and displays in working media liquid.The bubble of the dissolved gas producing separates with working media liquid, moves to the gas blanket being made up of air and working media steam on top.Therefore, the bottom of opposite heat tube shell is heated to have dissolved gas in working media liquid is separated and be discharged to outside effect.
Heat pipe package inside is full of and makes heat pipe or thermal siphon with the liquids and gases of working media, for can normally working, need to be discharged in atmosphere more than 2 times to the gas of major general's shell inside, that is, at least carry out above above-mentioned exhaust gas purification operation 2 times.
In addition, in the time that the number of times that repeats exhaust gas purification operation is more, can during exhaust gas purification operation, carry out the injection process of working media, i.e. operation 1, avoid thus, repeatedly in exhaust gas purification, working media being discharged too much, guaranteeing to fill enough working medias in shell.
In the present embodiment, adopt the linker with above-mentioned structure to connect the ozzle portion of shell, but be not limited to this, as long as can play the member of connection effect, as the connector such as valve, shaft coupling all can.
In the present embodiment, shell is tubular container, but is not limited to tubulose, can be also the container of plate other shapes such as grade, plays the container of heat pipe effect as long as injecting working media sealing.
In the present embodiment, be formed with the 1b of ozzle portion in shell main body 1a top necking down, seal formation heat pipe by ozzle portion being squeezed to flat cut-out after exhaust gas purification and welding, but the invention is not restricted to this, also can not form ozzle portion, but in shell main body, linker is directly installed, carry out the injection of working media and the discharge of gas by the switching of linker, after incoagulable gas is drained, linker cuts out, use as heat pipe product.
In the present embodiment, upper and lower three temperature sensors are set on shell, but be not limited to this, also can a temperature sensor be respectively set in heating part and shell main body top, and near the gas discharge outlet of shell injection end, gas sensor is set, also suitable heating-up temperature can be detected thus, and utilize gas sensor to judge the gaseous species of discharging from outlet, determine whether to carry out or stop thus exhaust gas purification.As long as determining heating-up temperature, judge the mechanism that whether drains incoagulable gas, all can be suitable for.
The shell of heat pipe is mostly metal seamless steel pipe, needs to adopt different materials, as copper, aluminium, carbon steel, stainless steel, steel alloy etc. according to difference.Pipe can be standard circular, can be also special-shaped, as ellipse, square, rectangle, pancake, bellows etc.Caliber can be from 2mm to 200mm, even larger.Length can be from several millimeters to more than 100 meters.The tubing of Cryo Heat Tube heat exchanger adopts copper, aluminium as raw material abroad mostly.Adopting non-ferrous metal to make tubing is mainly for requirement satisfied and working media compatibility.
