Description
The utility model relates to a kind of heat pipe, belongs to field of heat exchangers.
Heat pipe is that a kind of defeated heat energy power is big, the superconduction thermal element of the good reliable operation simple in structure of average temperature performance.Make the seal casinghousing pure water with carbon steel and make the steel of working medium/hydro-thermal pipe, have the high material of intensity and be easy to get, the wide advantage of the low adaptation of cost obtains using more widely, has all carried out large-scale research and application as power-saving technology at home and abroad.Be example only: straight rod type, U type (ZL92224358.1), plate, divergence type, open form (ZL91224443.7), dismountable open type (ZL87200256), dismountable open type (ZL91206688.1) are just arranged on integral form with steel/hydro-thermal pipe; Garden type, ellipse garden type, eccentric type (ZL90217283.2) and square etc. are arranged on the cast cross section; On the expansion heat-transfer area, serial finned type, helical fin type, longitudinal fin type (ZL89219488.X) ellipse garden sheet type (ZL92217362.1) are arranged.Pin type (ZL88217389.8), splayed configuration or buttferfly-type (ZL88102909.2); Light pipe type (ZL90106466.1) is arranged on the pipe inner structure, inhale and deploy cupric oxide type (ZL87103423) on stamen type, screw type (ZL92210004.7), electric pump upgrading type (ZL85102929), the condensation end and put combined oxidation formulation (ZL89102900.1); To in the inwall processing flange-type (ZL90106466.1) copper facing type and hot vanadate solution processing type (ZL86108394) being arranged; On working medium, there are pure water type and pure water to add the branch of slow release formulation again, do not give unnecessary details one by one.
These heat pipes overwhelming majority is disposable.Promptly make from heat pipe and drop into utilization, until heat pipe failure, disablement is scrapped, all can not the opposite heat tube repair and maintenance during this, make it to restore one's working ability.Both made heat pipe heat transfer property decline during operation, people also are willing and yet unable to help powerless, part reluctantly with what one treasures otherwise can only scrap in advance to change, and exist very big waste.Although the value that heat pipe is created is hundred times thousand times of cost own, this waste also has no reason to ignore.Someone says that " do not take place under chemical reaction and the incorrosive situation of pipe appearance at shell and working medium, the life-span of heat pipe is quite long in theory.Although " at present steel/hydro-thermal pipe Study on Compatibility bigger progress has been arranged, can not solve the consistency problem of steel/hydro-thermal pipe at all, just delayed the time and the degree of chemical reaction, won the time of industrial application.In fact waste heat recovery has only 5-7 years with the working life of steel/hydro-thermal pipe, and also will meet the requirement regulation of the provincial standard DB21/T-696-93 of Liaoning Province in production and the use.Someone talent moves trimestral steel/hydro-thermal tube elements continuously and cuts, and checks inside heat pipe, finds that tube wall has the material of one deck black, and the quality pine is dredged, the erasable removing.Once had postrun steel/hydro-thermal pipe dissected and do the working medium analysis, the transparent PH=9 of solution (seeing first heat pipe meeting material of China), once the someone dissected the steel/hydro-thermal pipe of inefficacy, found solution black, and PH=10.5 contains Fe (OH)
2Objective reality has illustrated steel/hydro-thermal pipe has been proposed the non-once use, the easy to exhaust fluid infusion that can be in operation, and can be in maintenance clean and change liquid, use the problem of the working life that prolongs heat pipe repeatedly.
The birth of heat pipe is used for aerospace at first, so development and application all require to meet disposable objective condition.Now steel/hydro-thermal pipe of using with waste heat recovery on the ground, has a great advantage than the heat pipe that is used on the space spacecraft, be exactly direct " treatment " that obtains people easily, people can implement maintenance management to it often, must still not go up the too many energy of waste " putting things right once and for all ".In the Chinese patent 87200256 " dismountable open type heat-pipe heat exchanger ", improved have dismountable upper end cover on the heat pipe, and heating water tank and working medium water tank are integrated, and steam is discharged from aperture.Because pipe has aperture to communicate, interior pressure is higher than atmospheric pressure, behind the steady operation, and intraductal working medium normal circulation, heat pipe and extraneous no mass exchange.After the long-term work, can open end cap and clean the continuation use.Its comply with one's wishes not to the utmost be in: after heat pipe quits work, negative pressure of vacuum influence in managed, to be filled water in the pipe, start slow when heat pipe is worked once more, after working medium must be seethed with excitement, part working medium is discharged to a certain amount of, could in pipe, carries out the cyclic process of evaporative condenser, this measures the not necessarily needed best working medium amount of adopting heat pipes for heat transfer, thereby heat pipe also not necessarily moves under optimum condition.Main is to do working medium with light water, easily forms incrustation scale in the pipe, influences heat transfer efficiency.Both enabled to clean, and also had the little length of heat pipe caliber long, it is little to pull down the end cap aperture, overhauls inconvenient halfway problem.Heat exchanger is again continuous operation mostly, has only finished a production cycle, the chance that just has maintenance to clean.This cycle time is longer, is far longer than the cycle that incrustation scale forms in the heat pipe, the situation that certainly will will cause heat pipe to work under low heat transfer efficient for a long time.
The purpose of this utility model, provide a kind of work easy to exhaust fluid infusion in service, steel/water-compatible there is not too high request, make things convenient for clean and change liquid during maintenance, Guan Bi is not under the very heavy situation that can adapt to work of corrosion and damage, can normally move with high-performance for a long time, and when the pipe internal pressure is higher than operating pressure, can the explosion-proof steel/water gravity type heat pipe of automatic vent step-down.
The utility model is real like this.Condensation end at heat pipe is provided with a demountable heat pipe end socket, the aperture that is interlinked to the outside in one is opened on this heat pipe end socket top, the end socket inner face is the recessed spherical crown surface of a garden arc, one steel ball that coincide with spherical crown surface is arranged all the time under the effect of spring force, imbed spherical crown surface, aperture is sealed, this spring screws the location and adjusts pressure by the spiral jackscrew that combines with heat pipe end socket inner thread, in order to guarantee steel ball and the sealing of end socket inner face in the certain pressure scope, the screw thread jackscrew has through hole, makes the interior remaining space of end socket become the temporary transient storeroom of heat pipe condensation end incondensable gas.
The operation principle of this heat pipe end socket is: when the need emission gases is made and moved to heat pipe, with specific purpose tool steel ball is depressed, made steel ball leave recessed spherical crown surface, discharging gas dome gas; When heat pipe repeatedly after the exhaust, intraductal working medium naturally can lossy minimizing, inserts aperture with specific purpose tool again and backs down steel ball downwards, to managing interior fluid infusion; Exhaust or fluid infusion all can be carried out in that heat pipe is in service, are suitable for when only the heat exchange of heat pipe that manufactures and designs especially being had implementation condition certainly; When heat pipe quits work, the condensation of pipe internal cause working medium forms negative pressure of vacuum, spring to the pressure of steel ball greater than atmospheric pressure, with external seal in the heat pipe, when the heat pipe internal pressure is higher than spring pressure, steel ball is subjected to the reaction force of spherical crown surface intraductal atmospheric pressure in the end socket, pushes steel ball open automatic steam discharge pressure-relief explosion-proof; Pressure is reduced to a certain degree behind the steam discharge, and spring pressure resets steel ball again greater than reaction force, stops steam discharge automatically and normally moves; When finished stop production to overhaul campaign, the detachable heat channel closure went out remaining working medium clearly with specific purpose tool, cleaned wiping in the opposite heat tube, removed dirt and changed new working medium, installed standby.
This heat pipe end socket can be used on the various forms of sealing heat pipes; factor affecting such as heat pipe cross sectional shape, working medium, expansion heat-transfer area not; certainly special adaptation garden tubing hot-pipe; if can with the pipe outer wall is had the fin synergy of protective effect; reduce the corrosion and the damage of tube wall; the steel of heat pipe/water-compatible research has major progress again; in addition the utility model is not afraid of steel/water again and is not allowed the incondensable gas that produces; the life-span of heat pipe also can be accomplished quite long not only in theory actually really.
The advantage that the utility model heat pipe is had mainly becomes disposable heat pipe the muptiple-use heat pipe that uses repeatedly, the working life that has prolonged heat pipe obviously with outstanding; Changed the key of decision heat pipe working life, transferred anti-corrosion protection to tube wall to by steel/water-compatible, as long as accomplishing in other words that tubing is not bad can usefulness, just there is not the problem of scrapping in heat pipe, and saves high efficiency; Because the pressure release function that surpasses the regulation operating pressure that heat pipe device itself has, the balance of holding tube internal pressure automatically in service prevents the superpressure blast, has improved the job security and the accommodation that has enlarged heat pipe of heat pipe; Owing to be not afraid of steel/water and do not allow to produce the hydrogen that causes the heat pipe operational failure, except that with pipe that working medium and steam directly or indirectly contacts in the normal Passivation Treatment of position need, needn't add again in the working medium and suppress the chemical products such as sustained release agent dispersant that hydrogen produces, particularly needn't add the bichromate and the chromate of poisonous contaminated environment harm humans health, help protecting the environmental protection mankind; Because regular meeting obtains people's treatment during heat pipe, makes it to guarantee to work under high efficiency, energy-saving benefit is obvious; Because heat pipe technology is simply manufactured easily, use and management is convenient, and is good in economic efficiency, is suitable for popularizing, can be rapidly with this superconduction hot body new and high technology of heat pipe, in all local large-area applications that needs the recyclable utilization of waste heat; Both be beneficial to universal new and high technology, be beneficial to the awareness of saving energy that improves and strengthen the whole society again, be more conducive to create bigger economic benefit and social benefit.
Below in conjunction with specific embodiment, discuss structure of the present utility model and operation principle in detail.
Accompanying drawing is a structural representation of the present utility model.The condensation end of heat pipe has heat pipe end socket (2) and shell (1) with being threaded, end socket (2) part precession shell (1) is sealed, have on the end socket (2) one with heat pipe in the outer hole (4) straight in the platform side, garden that is that communicates, the interior top of end socket (2) is an indent spherical crown surface, have one with the spherical crown surface good steel ball (3) that coincide, pushed down with the spring (5) that the spiral jackscrew (6) that is threaded compresses and locatees with end socket (2) inwall, steel ball (3) is pressed in the interior depression spherical crown surface of end socket (2), adjust the depth degree of precession screw thread jackscrew (6), can change the pressure of spring (5) to steel ball (3), spiral jackscrew (6) has aperture (7), end socket (2) interior remaining space air gas dome (10) is communicated with the heat pipe bottom, heat pipe bottom splendid attire working medium (8), end cap (9) is with the evaporation ends sealing of heat pipe bottom.
Screw off end socket (2) before the heat pipe operation, an amount of working medium (8) is added in the heat pipe, screw end socket (2) again, note sealing.Evaporation ends was heated when heat pipe started, and working medium (8) explosive evaporation is got into gas dome (10) in the end socket (2) with inner air tube, and (4) push away steel ball (3) to pressing down from the hole with specific purpose tool, air along the spherical crown surface slit of throwing off outside the discharge pipe of hole (4).Through exhaust several times, can be with the air emptying in the heat pipe, i.e. atural beat vacuum pumping method.The also available vavuum pump pump drainage that the transition suction nozzle is arranged.In the heat pipe no matter directly with the indirect position that contacts with working medium or working substance steam, adopt which kind of method Passivation Treatment, also no matter working medium (8) is pure aquae destillata or has added sustained release agent, and heat pipe initial operating stage hydrogen output is all more, and the method for available during this period of time emptying gas is discharged hydrogen.Available hand is touched the temperature of end socket (2), whether forms vapour lock in the access tube, and whether decision needs exhaust.Along with the heat pipe increase of running time, check that also can increase the blanking time of venting, but every month only lacks exhaust once.Repeatedly after the exhaust, working medium (8) can reduce, and the available dedicated instrument quantitatively replenishes working medium.
