Description
Technical field
The present invention relates to a kind of heat transfer unit (HTU), be meant that especially a kind of working media in being contained in the seal cavity is under the suitable operating mode, do not need to come a kind of non-phase-change heat transfer device of transferring heat energy via the phase transformation of working media, with and preparation method thereof.
Background technology
Heat transfer is the meaning of transferring heat energy, be one of important procedure in the countless industries, the thermal management program of chemical industry program, space flight and aviation industry and electric industry for example, any industrial plants no matter all need heat, move heat or interim heating or move the program of heat.Heat transfer can be divided into three major types, i.e. conduction, convection current and radiation, and conducting heat basically is the process that heat energy is transferred to an end of religion low temperature from an end of higher temperatures, in other words, any system that contains temperature or barometric gradient no matter be in medium or between medium, all can produce heat transmission.
Heat pipe is the passive type heat transfer unit (HTU) of a high-termal conductivity, and the two-phase heat transfer structure in the heat pipe is promoted to several thousand times with heat conductive efficiency from 100 times of copper.Heat pipe generally comprises a sealed tube, be filled with working fluid, as the medium that conducts heat, under operating mode, when the end with heat pipe heats, be evaporimeter, working fluid produces temperature and barometric gradient through vaporization in heat pipe, described temperature and barometric gradient force gas to prolong the condensation end that heat pipe flows to heat pipe, be condenser, discharge latent heat, and then make working fluid flow back to the evaporimeter heat absorption.The heat conductive efficiency of working fluid two-phase (liquid and gas) circulation is good than solid metallic in the heat pipe.
Now, the existing many many heat pipes of all being known, for example capillary formula heat pipe, pulsation type heat pipe and gravity type heat pipe all have outstanding heat conductive efficiency though proved above-mentioned heat pipe, also some defective still.
Capillary formula heat pipe is the class in the heat pipe, the another side that can rely on capillary force that liquid and gas are transmitted from one side of heat pipe, described heat pipe is to form with metal tube, the metal tube inwall is covered with capillary structure, capillary structure then is filled with working fluid, according to the difference of design and application, when utilizing the capillary structure internal pressure that liquid transfer is arrived under the situation on one side, capillary structure only gets and needs liquid transfer to another side.
Pulsation type heat pipe includes a capillary, the continuously moving road that has many revolutions and link to form on the capillary, and wherein, loop and link are arranged on evaporimeter and condenser place to replace arrangement mode.Earlier capillary is emptied, with a partially filled liquid, after heating, described liquid is distributed in the capillary with vapour-liquid attitude bulk or air bubble-shaped form, described heat pipe need maintain under the non-equilibrium work condition state, rely on continuously pipe interior, transmit vapour-liquid piece or vapour-liquid bubble through the caused pressure fluctuation of being heated.
Gravity type heat pipe then for simple relatively structure, includes the sealed tube that an inside is filled with working fluid.Under the situation of running, the liquid that is positioned at evaporator end is through the heating vaporization, and in sealed tube under the small pressure differential, described gas flow to condenser, discharges heat, and liquefaction, and described liquid then relies on gravity to flow back to evaporimeter.Gravity type heat pipe is respectively arranged with the room of gas fluid capacitance chamber and liquid stream usefulness, described evaporimeter need be arranged on and be lower than the condenser place, when the gas in the heat pipe was saturation state, the pressure in the heat pipe was relatively very small, and the temperature in the heat pipe is consistent.
Up to the present, Heat Transfer of Heat Pipe on Heat Pipe usefulness still has some restrictions, viscous force is one of them restriction, when heat pipe is being lower than temperature when running under the suggestion operational temperature, viscous force can hinder gas flow in the heat pipe, and this situation is to cross when small in evaporimeter and condenser two interregional pressure differentials, just can take place.For promoting the operational temperature of heat pipe,, need to select suitable working fluid, and specifically demand is used, and has limited the kind of working fluid at the different application demand.
Another limiting factor is the velocity of sound restriction, and the velocity of sound restriction occurs in when air-flow reaches velocity of sound, and gas flows with the speed of velocity of sound, makes to produce in the heat pipe to block.
And another limiting factor is for dispersing restriction, and when gas flow rate was too high, too high gas flow rate stoped the condensation Returning evaporimeter, and then produces the situation that dropping liquid disperses at condenser, and makes evaporation ends dry.
And another limiting factor is capillary restriction, when REFRIGERATION SYSTEM DRIVEN BY CAPILLARY FORCE power that working fluid produced in greater than heat pipe of the air pressure in the heat pipe and/or gravity, the capillary restriction can take place then, and the capillary restriction hinders working fluid and flows back to evaporimeter, and then makes heat pipe dry.
Moreover another limiting factor is boiling restriction, arrives under the situation that is enough to produce nuclear boiling at heat and takes place, and makes to form bubble in the capillary structure, stops working fluid, and further makes evaporimeter dry, produces huge thermal resistance.
Another limiting factor is the draw ratio restriction, it is long that draw ratio is limited in heat pipe length, take place under the situation of generation high length-diameter ratio, in the case, there is working fluid can't flow back to the tendency of evaporimeter, produce the dry phenomenon of heat pipe, this kind restriction major part is only influential to the heat pipe that utilizes capillarity transmission working fluid.
In addition, the heat transmission in the heat pipe is for the sensitivity of the heavy position utmost point, and pulsation type heat pipe is one of heat pipe that is subject to this restriction.
The objective of the invention is to provide a kind of method of not having the phase-change heat transfer system, and a heat transfer unit (HTU) that utilizes the method to make, to overcome the restriction of traditional heat transfer unit (HTU).

The specific embodiment
Some concrete and alternative embodiment that are consistent with above-mentioned explanation by following provide, can more clearly understand novel features of the present invention, and the personage Ying Ke of affiliated technical field provides in nothing under the situation of this specific detail, finishes the application of this invention smoothly.For not fuzzy this case invention focus, some details can't be described in detail, is easy to reference for making picture and text, and the element in all diagrams will be with identical explanation symbology.
Fig. 1 is the heat transfer unit (HTU) 100 that one of them embodiment illustrated according to the present invention.Described heat transfer unit (HTU) 100 includes a cavity body 101 and a working media 102, and described cavity body 101 is one to accommodate the housing or the container of the sealing of working media 102.Described cavity body 101 and described working media 102 boths are heat-conducting.Described heat transfer unit (HTU) can suitably operate under operating mode, relies on working media 102, one side with the be delivered to another side of heat from cavity body 101.Under the situation of running, to the part of the cavity body 101 of heat transfer unit (HTU) 100 with thermal source 150 heating (towards the direction shown in the arrow 151), heat energy relies on working media 102 to scatter whole heat transfer unit (HTU), because the temperature of other parts of heat transfer unit (HTU) 100 and working media 102 is subjected to that part of thermal source 150 heating low, therefore heat energy be delivered to the lower place of temperature.Because the temperature in the cavity body 101 rises, therefore working media 102 is expanded, and reaches the temperature of operating mode until the temperature of working media 102.Because of cavity body 101 is so that a seal is the also rising accordingly of its internal pressure.When the degree that the temperature and the pressure of working media 102 reaches operating mode, the heat energy that heat transfer unit (HTU) 100 is distributed is then with the optimum speed transmission.Temperature around heat transfer unit (HTU) 100 is low than heat transfer unit (HTU), and heat energy then is dissipated to around (towards direction shown in the arrow 152) heat transfer unit (HTU).
Still consult Fig. 1, when with heat transfer unit (HTU) 101 heating, heat transfer unit (HTU) can carry out start-up routine, and wherein, the effect that is subjected to free convection when working media 102 produces phase transformation and pulsation situation thermal enlargement (the volume change of heat) program in brief.Time Cold Boiling takes place when hot-fluid increases rise bubble constantly generation in phase transformation.Working media absorbs heat and expands the upper space that fills gradually at saturated bubble.When hot-fluid is higher, in the time of phase transformation, will produce the bubble fracture phenomena.Bubble piece and fluid block occur in succession and pulsation phenomenon take place.When the space of bubble further dwindled, total system was moving by light sea, the ultrasonic vibration is rung in pulsation, the light whistle.In these programs, be applied to cavity body 101 from the pressure 104 of working media 102, this has increased the internal pressure of cavity body.When the temperature of working media 102 and pressure reached poised state, working media 102 reached optimum condition.Under poised state, the working media 102 in the heat transfer unit (HTU) 100 is being in fact that equal densities is full of whole cavity body 101 in whole cavity body 101.When the thermal enlargement in the sealed cavity body 101 was pressed, phase-change heat transfer reduced and last complete obiteration greatly.So working media 102 is kept and is controlled at homophase and do not had phase transformation and produced, and that is to say no phase transformation.Under this stage, the newly-increased heat energy that is applied to the part of working media 102 is transmitted to another part via the expansion of the heating power effectiveness of working media 102 and contraction.Because heat propagation efficient height, to keep low-heat poor for execute heat part and other part of heat transfer unit (HTU) 100, is typically under 1 ℃.In other words 3 remarkable different heat transfer patterns are arranged in heat transfer unit (HTU), promptly are that free convection heat transfer, phase transformation and pulsation are conducted heat and do not had phase-change heat transfer.Changing by free convection heat transfer that phase transformation and pulsation conduct heat into is that boiling point with working media 102 is a mark.Changing phase transformation into by free convection heat transfer is with the complete full state of the reality of working media 102 with the pulsation heat transfer.Reach the heat propagation in the heat transfer unit (HTU) 102, working media 102 cavity body 101 of will under temperature under the required operating mode and pressure, packing into.
The convection current of working media 102 is that the pressure differential by the evaporimeter of heat transfer unit (HTU) 100 and condenser is caused.This convection current has the ability to keep no phase-change heat transfer pattern.Under no phase-change heat transfer pattern, heat transfer is to realize with the interaction of pressure oscillation via the input of the heat in the closed system.A small temperature change will cause the significant stress in the system to change.For example, the temperature increase will cause pressure to increase by 1 to 100bar pressure for 10 ℃.This for the reaction pressure of temperature also according to the geometry of the kind of working media 102 and heat transfer unit (HTU) 100 and decide.Therefore, when temperature in evaporimeter, continue to increase with condenser in when reducing, huge pressure differential will produce at the two ends of heat transfer unit (HTU) 100.Make to conduct heat and taken place at raise mixed effect that pressure with condenser reduces of the pressure of evaporimeter.This working mechanism is different with the phase-change heat transfer pattern, and for example the circulation of working media is according to gravity or capillary force in the gravity assisted heat pipe; And heat transfer is to produce by means of the interaction of the change of the heat of medium and volume.
In the ideal, when cavity body 101 is sealing, working media 102 has been full of whole cavity body 101 with equal densities always.Under certain situation, anyway, according to used working media 102, working media 102 closes steam with the liquid and full of balance, is present in the cavity body 101 of sealing in room temperature or off working state.
Duty among Fig. 1 is to be certificate with the operating temperature in effective operating temperature or certain scope.Its target application that is based on heat transfer unit (HTU) 100 is selected.Heat transfer unit (HTU) 100 is adjusted into the working media of keeping in the cavity body 102 and keeps and provide optimal heat to propagate under the no phase transformation state under this duty.For example, pine for heat transfer unit (HTU) 100 and be adjusted to 800 ℃ (temperature of working media) down effect when adding, and when temperature the following heat transfer unit (HTU) 100 that is being lower than 800 ℃ will be relatively down than common conventional heat pipe than anergy.Yet when working media reaches 800 ℃ or higher, the heat of heat transfer unit (HTU) 100 transmission efficiency ratio conventional heat pipe can promote according to exponential manner.
According to an embodiment, fluid is elected suitable working media as.Fluid can be gas or liquid.
With the example of Fig. 1, the heat that thermal source 150 is sent can be led heat transfer under all temperature.
According to an embodiment, one side liquid such as water are available as working media 102 with conducting heat to another side from heat transfer unit (HTU) 100.When one side of heat transfer unit (HTU) 100 receives outside heat, the heated liquid in the cavity body 102 and begin expansion.Molecule in the liquid is heated and begins to transmit suffered heat to the lower molecule of temperature that connects.Therefore, the liquid in the cavity body 101 gradually and average increase pressure.When the temperature of liquid reaches duty or operating temperature, used pressure when the operating pressure of liquid equals to pack working media 102 into cavity body 101 in fact.In this stage, Yi Bian heat begins from being transmitted to another side.It is also noted that described liquid is control and is maintained not evaporation of liquid.Fluid density in the cavity body 101 has and the different densities under room temperature and pressure usually.
According to another embodiment, the using gases medium is that the working media 102 of heat transfer unit (HTU) is cold to pass.It is with a method effect similar but opposite with above-mentioned heat transfer.In biography was cold, gas was to control and be maintained gas not liquefy in biography is cold.
According to the present invention, heat is to propagate in seal, therefore, does not have the restriction in direction or orientation.Furtherly, the simplicity of design of heat transfer unit (HTU) 100 need not provide any capillary structure that makes the design complexity of heat transfer unit (HTU).Moreover, the size of heat transfer unit (HTU) 100, because of the design of simplifying more less than conventional heat pipe.Its internal diameter can be less than 1mm.
According to the present invention, any material can be used for cavity body 101 and working media 102.For the event of safety, the material that is used for cavity body 101 is essential enough firm in to suppress temperature and the pressure of working media under operating mode and non-operating mode.Furtherly, the selection of working media 102, needing according to the thermal conductivity of material under operating mode is that specific operating temperature and pressure limit selected.Remove some known highly heat-conductive materials such as mercury (mercury) and sodium (sodium), other material such as alcohol (ethylalcohol), ether (ether), benzene (benzene), acetone (acetone), ammonia (ammonia), freon (Freon), argon (argon), carbon dioxide (carbondioxide) etc., also applicable.The material that cavity body is suitable for comprises: copper, aluminium, stainless steel, steel, iron ... or the like.
Fig. 2 shows, according to the manufacture method of the heat transfer unit (HTU) 100 of one embodiment of the invention.Described method comprises: the cleaning cavity body 101 of step 201; The working media 102 that the installation of step 202 is suitable for; And the sealed cavity body 101 of step 203.In step 201, cavity body 101 is cleaned to remove to be polluted or any unwanted other object.In step 202, working media 102 is installed in cavity body 101.Working media 102 is expansion or the contraction states that are installed in this operating mode under the temperature of the operating mode that heat transfer unit (HTU) expectation is used and pressure.When cavity body 101 has been full of working media 102, sealed cavity body 101 is to keep working media 102 in inside.
According to the present invention, in no phase-change heat transfer device, do not need the circulation of phase transformation.Therefore, do not need the restriction of capillary effect and capillary not exist.The heat transfer power of initial conditions is temperature dependent difference and the convection current of the working media that produces.According to the present invention, heat transfer system is to use temperature in the cavity body 101 and pressure differential to reach heat propagation under the operating mode that requires.
Can recognize, require under the operating mode or when the working media 102 of heat transfer unit (HTU) 101 under non-working condition, can 2 be present in mutually in the cavity body 101 non-.Yet,, when heat transfer unit (HTU) is that medium in operating mode cavity body of following time 101 is to exist for one of liquid or gas in the specific function condition and range, non-ly exist simultaneously according to the present invention.
Heat transfer unit (HTU) 100 reaches best efficiency when working media 102 reaches specified temp and pressure.For example, use normal water as the working media fluid 40-500 ℃ of following usefulness the best.The identical water of heat output has good usefulness in 150-1800 ℃ on the ring of the whistle of no phase transformation heat pipe is, and need reach about 2500 ℃ to reach its best best efficiency of heat output down.
Select temperature and pressure environment that working media 102 is installed in the cavity body 101 based on the operating mode of needs.According to one embodiment of the invention, according to an embodiment who needs, the temperature of selection can be and is higher than the temperature that needs operating mode about 30% or higher.For example, if the operating mode that needs is 1500 ℃, the temperature of selection can be about 2000 ℃.Suppose that water is to elect working media as, water heats under 16 standard atmospheric pressures (atm) and is encapsulated in the cavity body 101 when water temperature reaches 2000 ℃.Be maintained liquid state at this stage water.
According to the present invention, not dry in the present invention restriction is full of by working media because of cavity body, also may be the saturated vapor with material, therefore, can not undergo phase transition in the heat transfer state.
