Description
Technical field
The present invention relates to the heat transfer technology field, particularly relate to a kind ofly for " air-air " system, utilize in the Working fluid phase changing process to absorb or the principle of release heat, do not need the outer energy of the amount of imports can transmit the Three Dimensional Thermal pipe in pipe of very high heat flow.
Background technology
So-called heat pipe generally includes a condensation end and an evaporation ends, and condensation end and evaporation ends interconnect, and forms the system of a sealing.With reference to figure 1, typical heat pipe 6 is comprised of the pipeline 8 of a sealing, and a wherein end of pipeline 8 consists of evaporation ends 10, and the lower other end of temperature and pressure consists of condensation end 12.Liquid-sucking core 14 to condensation end 12, runs through whole heat pipe from evaporation ends 10.By the auxiliary heat dissipation of fin 15, can with heat from evaporation ends environment on every side, be delivered in the condensation end environment on every side and go.
In the course of work of heat pipe, liquid working substance 11 evaporates behind the absorbing environmental heat in evaporation ends 10, evaporation becomes steam state and rises to condensation end 12, is become liquid and releases heat by environment cools again at condensation end 12, and liquid is back to again evaporation ends 10 at last under the effect of capillary wick 14.This circulation constantly repeats, thereby with the heat in the evaporation ends environment, is delivered to continuously in the condensation end environment and goes.
As shown in Figure 2, in the existing technology, by a plurality of independent heat pipes 20 are assembled into an integrated heat exchanger 21, increase the heat-transfer capability of heat exchanger.Each independent heat pipe structure and operation as shown in fig. 1, that relatively single heat pipe will be large on heat-transfer capability is many for the heat pipe of assembling like this.But because every pipeline all must be filled the refrigerant of right quantity individually, thereby its production technology can be very loaded down with trivial details.
Such as Fig. 3 A and 6A, manufacturing and installation cost in order to reduce heat pipe can utilize U-shaped pipe, and single heat pipe is connected into snakelike heat pipe.By the connection of U-shaped pipe, can reduce the part producing cost.But, each root pipeline of this type of heat pipe, very difficult assurance can both obtain enough work refrigerants, and such serpentine coil structure may hinder in addition flowing of whole inside heat pipe liquid, and then reduce its whole heat transfer efficiency.Only have when snakelike heat pipe vertical direction is placed, namely with the serpentine coil of upper part as condensation end, the serpentine coil of lower part is as evaporation ends, snakelike like this heat pipe could work.In order to guarantee that every pipeline can both obtain the work refrigerant of q.s, each coil pipe need to be pooled together by a manifold trunk.As shown in Figure 3A, the end of each U-shaped pipe 30A pools together in this manner in the heat pipe, and liquid working substance just can flow freely between tube and tube like this, thereby guarantees that all ducted liquid level 34A can both be identical.And more specifically, the bottom 35A of U-shaped pipe 30A is perforate, and they is interconnected with tiny copper pipe 36A at the eyelet place.The openend of adjacent U-shaped pipe then by a straight tube 37A, pools together them.Such connection can make the end of adjacent channel mutually connect, and guarantees that all ducted liquid levels can both be identical.At the inwall of every pipeline 30A, make little groove 33, and put aluminium fin 32 at pipeline external, so just consisted of heat pipe exchanger.
Utilize in the configuration of snakelike heat exchanger at another, the heat exchanger of two horizontal positioned can be interconnected, wherein be in the part of lower position as evaporation ends, and the part of another higher position is as condensation end.As shown in Figure 6A, by a copper pipe 63A, the U-shaped pipe 60A that will be in lower position pools together.Take same mode, with another root copper pipe 64A, the U-shaped pipe 61A that will be in the higher position pools together.The top of manifold trunk links to each other with a copper pipe 62A, and as evaporation tube, the below of manifold trunk links to each other with a copper pipe 65A, as return duct.
As shown in Fig. 3 A and 6A, each equipment operational excellence.But the two is producing and is installing all relatively difficulty, thereby causes its application to be subject to many restrictions.
In addition, the work of the said equipment is all based on this basic principle of Action of Gravity Field.Refrigerant is back to evaporation ends under action of gravitation after condensation end is condensed into liquid, and produce the reason of Action of Gravity Field in the system, then is because condenser is different with the height of evaporimeter present position.In order to guarantee that these equipment can effectively move, the height of condensation end must be higher than the height of evaporation ends.Therefore, if do not arrange according to above-mentioned requirements, these equipment can not normally move.
In addition, heat pipe can be used to increase moisture removal or the efficient of air-conditioning system.As shown in figure 13, such air-conditioning system 110 has comprised a surface cooler 124 and the heat pipe exchanger 126 for increasing the air-conditioning system moisture removal.This heat pipe is comprised of a pair of manifold trunk heat exchanger shown in Fig. 6 A.First heat exchanger 128 is as evaporation ends, is installed between air-conditioning air inlet and the surface cooler 124.And second heat exchanger 130 then is installed between surface cooler 124 and the unit air outlet, as the condensation end use of heat pipe.Heat exchanger 128 and 130 interconnects by evaporation tube 134 and return duct 140.
Above-described heat pipe can significantly improve the operational efficiency of air-conditioning, increases the moisture removal of surface cooler.But the heat pipe structure form of this collective-type is more fixing, and used serpentine coil needs extra machining, and manifold trunk need to be linked to each other with the end of every U-shaped pipe.Therefore, the manufacturing of this heat pipe is difficulty relatively comparatively speaking, so that their application in many aspects, comprises that the application in a lot of conventional air-conditioning system becomes unrealistic.

The specific embodiment
The present invention is further described below in conjunction with accompanying drawing.
According to the present invention, the heat pipe exchanger form of expression is snakelike heat pipe, and by the connection of U-shaped pipe, heat pipe can form fully continuous coil pipe.
Shown in Fig. 3 B, the heat pipe exchanger 38 of made according to the present invention interconnects by the openend of U-shaped elbow 31 with adjacent U-shaped pipe 30, thereby consists of snakelike heat pipe 36.Heat transmission fin 32 on the heat pipe outer cover, and preferably aluminous fin consists of snakelike heat pipe exchanger 38.Every U-shaped pipe 30 does not use liquid-sucking core, but makes little groove 33 at the inwall of pipeline, can carry out the transmission of more heats.
Such as Fig. 4, the snakelike heat pipe of more than addressing can be made Integral type heat-pipe heat exchanger 40 after adding fin and framework, and in the central authorities of heat pipe exchanger 40, do an adiabatic section 41, heat pipe 44 is divided into up and down two parts, and upper part 43 is as condensation end, and lower part 42 is as evaporation ends.When the higher air of temperature through heat pipe exchanger 40 lower parts 42 time, refrigerant is subjected to thermal evaporation in the pipe, and steam rising is to the upper part 43 of heat pipe exchanger 40, when the lower air of temperature through out-of-date, the interior refrigerant condensation of pipe is also emitted heat.Condensed refrigerant liquid is back to again the lower part 42 of heat exchanger, the afterwards continuous repetitive cycling of this process by little groove of inner-walls of duct.
As shown in Figure 5, several snakelike heat pipes 50 described in Fig. 3 and Fig. 4 can be arranged to many rows' 51 form, consist of an Integral type heat-pipe heat exchanger 52, thereby can strengthen the heat-transfer capability of heat pipe exchanger.
Such as Fig. 6 B, snakelike heat pipe 64 also can be divided into two independent parts.This heat pipe comprises: one group of serpentine coil 60 forms the lower snakelike parts 65 in position, as the evaporation ends of heat pipe; One group of serpentine coil 61 forms the higher snakelike parts 66 in position, as the condensation end of heat pipe.With described the same before, serpentine coil 60,61 all is comprised of a plurality of U-shaped pipes, and these U-shaped pipes have adjacent openend and by U-shaped elbow 67 rather than a straight copper tube, are connected to together.Fact proved, this configuration is identical with the heat pipe exchanger effect of compiling tubular type that reaches described in Fig. 6 A, but when producing assembling, but wants much simple and economical.Snakelike parts 65 and 66 interconnect by evaporation tube 62 and return duct 63, thereby consist of a split type heat pipe 64.
As shown in Figure 7, several separated heat pipes 70 can be combined, and with return duct 73 snakelike parts are linked to each other by evaporation tube 71, consisting of a heat pipe exchanger 72 that comprises evaporation ends 74 and condensation end 76, the evaporation ends of this heat exchanger and condensation end all comprise several serpentine coils.The same to the form of Fig. 5 with Fig. 3, the evaporation ends of heat pipe exchanger and condensation end, all overlapping has aluminous fin 78 to strengthen the heat-transfer capability of heat pipe.
Heat pipe and heat pipe exchanger can be used for increasing the moisture removal of existing air-conditioning unit.The evaporation ends of snakelike heat pipe exchanger is placed on the air intake place of air conditioner watch cooling, is used for the air that enters system is carried out pre-cold-peace dehumidifying; Condensation end then is placed on the wind outlet of surface cooler, and the air after excessively cold is carried out again heat.
As shown in Figure 8, snakelike heat pipe exchanger 89 is installed in the existing air-conditioning system, wherein evaporation ends 80 is installed in the air conditioner watch cooling 85 return air air-flow 82 before, and condensation end 81 then is installed in the air-supply air-flow 88 of air conditioner watch cooling 85 back.Such layout can make refrigerant evaporate in evaporation ends 80 and rises to condensation end 81.By surface cooler 85 cooled air, by hot again, then send into indoor by blower fan 84 during through condensation end 81.Be arranged in the refrigerant of evaporation ends 80, absorb heat in the return air air-flow 82 by evaporation, and the air that does not also enter surface cooler 85 is carried out precooling.The effect of this precooling is to make surface cooler 85 can separate out more condensed water 87.Refrigerant in the snakelike heat pipe exchanger 89 rises to condensation end 81 after evaporation, subsequently condensation and to the air-supply air-flow 88 in releases heat.
After processing like this, the relative humidity of air-conditioning can be lower, is particularly suitable for using in some areas that have a humid climate and some industry and the business environment.To the air in the air-conditioning system do pre-cold-peace again heat treatment a lot of benefits are arranged, also can save a large amount of energy simultaneously.For example, air-conditioning return air 82 is carried out precooling, snakelike heat pipe exchanger 89 can reduce the cooling load of compressor of air conditioner.In addition, by reducing the relative humidity of air-supply, the setting running temperature of air-conditioning can improve, and also can reach identical comfortable effect.In addition, provide free again heat by heat pipe, can replace used hotter measure in the current MCS, thereby can save the energy that reheat system consumes.
As shown in Figure 9, can more clearly understand the operation principle that is used for the snakelike heat pipe exchanger of dehumidifying in the air-conditioning system.Suppose that the air-conditioning return air temperature is 35 ℃, the evaporation ends 92 through snakelike heat pipe exchanger 99 transfers heat in the refrigerant of heat pipe, so that refrigerant evaporation.This heat transfer makes the air cooling through evaporation ends 92, supposes that air themperature drops to 33 ℃.Air after the precooling through surface cooler 94 coolings and dehumidifying, supposes that the leaving air temp behind the surface cooler 94 is 13 ℃ subsequently.Airborne moisture is discharged from as condensed water 95 after condensing through surface cooler 94.Cross air 96 after cold again through the condensation end 97 of superheater tube, the heat that absorption condensation end 97 transmits from evaporation ends 92 is heated to a comfort temperature such as 15 ℃.After condensation end rejected heat in the air, the refrigerant in the heat pipe condensed and is back to evaporation region 92 at condensation end 97.Air after the heat 98 is sent from air-conditioning system again.
This by utilizing snakelike heat pipe that the return air in the air-conditioning system is carried out precooling, and air-supply carried out again heat-treating methods, both can be applicable to such as Fig. 3 in Integral type heat-pipe heat exchanger shown in Figure 5, also may be used in the Split type heat pipe heat exchanger as shown in Figure 6 and Figure 7.In addition, the layout pattern of snakelike heat pipe exchanger in air-conditioning has a variety of.Practical mode such as Fig. 8 are to shown in Figure 12, and wherein Fig. 8, Fig. 9 and Figure 10 are the layout patterns of Integral type heat-pipe heat exchanger, and Figure 11 and Figure 12 then are the layout patterns of Split type heat pipe heat exchanger.
The mounting means of unit-type heat exchanger in air-conditioning system can be the vertical installation among Fig. 8, Fig. 9, also can be that the level among Figure 10 is installed.As shown in figure 10, unit-type heat exchanger 102 is exactly the form that level is installed.The snakelike heat pipe in the over-heat-exchanger is not more prone to the evaporation ends that the position is lower 104 and is placed in the return air air-flow 106, and the condensation end 105 that the position is higher is placed in the air-supply air-flow 107.Fin 103 is used for strengthening the heat-transfer capability of heat pipe exchanger 102.Its operation principle is identical with the described principle of Fig. 9 with prior figures 8.
As shown in figure 11, split type snakelike heat pipe exchanger 110 also can be mounted obliquely within the air-conditioning system.By blower fan 117 with return air air-flow 115 drawing-in systems.Be in the lower evaporation ends in position 112 in the heat exchanger 110, be installed between return air air-flow 115 entrances and the air conditioner watch cooling 111; 113 higher of condensation ends of position are installed between air conditioner watch cooling 111 and 116 outlets of air-supply air-flow.Evaporation ends 112 and condensation end 113 can be used Fig. 6 and mode shown in Figure 7, and some row's serpentine coils are combined.Between the below evaporation coil and top condenser coil of each separated heat pipe, the tube connector 114 that all is comprised of corresponding evaporation tube and return duct interconnects.
As shown in Figure 12, when air conditioner watch cooling 121 is vertically placed, also can use Split type heat pipe heat exchanger 120, form is similar with Fig. 6 and Fig. 7.The lower evaporation ends 127 in position is arranged in the position that is positioned in the return air air-flow 125 before surface cooler 121 air intakes in the heat exchanger 120, and evaporation ends 127 is by two 122 stacking compositions of split type snakelike heat pipe, and one of them is installed in another top; The higher condensation end 128 in position is arranged in the air-supply air-flow 126 in the heat exchanger 120, and condensation end 128 is by two 123 stacking compositions of split type snakelike heat pipe.High and low two parts of each heat pipe are comprised of serpentine coil, and interconnect by connecting pipe 124.The same with description before, air-conditioning return air is evaporated end 127 precoolings, holds 128 again heating by being condensed again behind the surface cooler, thereby can strengthen the dehumidifying effect of air-conditioning unit.
Certainly, the snakelike heat pipe exchanger among the present invention might not need to be installed in the air-conditioning system the inside according to above-described mode fully.Only system need be designed as follows and get final product: with the evaporation ends in one or more snakelike heat pipes, be placed on before the surface cooler of air-conditioning system, first return air is carried out precooling; It is wind pushing part that condensation end is placed on the surface cooler back, to heating from surface cooler cold wind out again.
Except above-described snakelike heat pipe exchanger, the present invention also comprises the heat pipe exchanger of the continuous loop pipeline shown in all application drawing 6B.The loop pipeline comprises two parts continuously, and first can be used as the evaporation ends of heat pipe, and the condensation end that second portion can be used as heat pipe carries out work.Loop ducted " continuously " represents that this pipeline only has an indivisible single loop continuously.And " loop " represents that this pipeline itself includes a passage, and refrigerant can move in whole pipeline like this, and can get back to the position at its initial place.In this definition, pipeline also includes an adiabatic section that is positioned at the middle part.But this pipeline does not comprise existing technology part as shown in Figure 6A.
As mentioned above, in Fig. 6 B, showed one according to the present invention the Split type heat pipe heat exchanger of made, it is comprised of several U-shaped pipes.Separated heat pipe 64 also is a continuous loop pipeline simultaneously.Particularly in fact the heat pipe shown in Fig. 6 B 64 is exactly a long continuous loop pipeline.This loop pipeline comprises a first, i.e. the snakelike part 65 of lower, position is as the evaporation ends of heat pipe; Also comprise a second portion, i.e. the snakelike part 66 of position higher position is as the condensation end of heat pipe.Because the heat pipe shown in Fig. 6 B is actually one with long continuous conduit, when heat pipe was installed in the air stream, the pressure reduction between different snakelike regional 65 and 66 will promote refrigerant mobile in whole pipeline.
According to top described, the separated heat pipe 74 shown in Fig. 7 is installed in the heat pipe exchanger 72.Because separated heat pipe 74 do not need the discrepancy in elevation of position to get final product work, so heat pipe exchanger 72 can be stuck in the installation of carrying out horizontal before and after the surface cooler.
Separated heat pipe 64 because the air-flow amount that different parts heats in the opposite heat tube through superheater tube the time is all different, thereby forms pressure reduction at inside heat pipe in use.This pressure reduction is so that refrigerant can pass through whole pipeline in the mode of infiltration.Because the characteristic of the continuous loop pipeline of separated heat pipe 64, when its level was installed, all serpentine coils 60 and 61 in the snakelike part 65 and 66 all can normally move.When all are addressed the heat pipe level and install, all represent snakelike regional 65 and the plane at 66 places should be perpendicular to the ground.
Therefore, for the utilization of U-shaped pipe, realized a purpose of aforesaid invention.Heat pipe also can work under the condition of not utilizing difference in height, can be used as an extra purpose of the present invention.
Below be two other continuous loop heat pipe forms.
As shown in figure 14, with a continuous loop pipeline 200, be made in the Integral type heat-pipe heat exchanger 205 and use as heat pipe.This continuous loop pipeline 200 has comprised one snakelike regional 203 and one non-snakelike regional 204.In this most preferred embodiment, non-snakelike zone is form of straight lines.But, non-snakelike regional 204 that show in Figure 17 is curve form.
Described according to this most preferred embodiment, first 201 only consists of the first of snakelike regional 203 in the continuous loop 200.The second portion of continuous loop pipeline 200, then by snakelike regional 203 second portion, and non-snakelike zone (being straight tube) 204 forms.Non-snakelike regional 204 become an integral body with snakelike joint area.
Although the continuous loop pipeline that this most preferred embodiment embodies is the form of snakelike parts.But we will understand, as long as pipeline can be separated into two parts, and can use as evaporation ends and condensation end respectively, no matter what form pipeline is made and all be fine so.For example, this continuous loop pipeline, can be one simple circular, oval, also can be one square.
As shown in figure 15, loop pipeline 200 is positioned on the plane 210 continuously, and Integral type heat-pipe heat exchanger 205 is comprised of a pipeline 200 and fin 206.
Figure 16 is another collocation form of the Integral type heat-pipe heat exchanger shown in Figure 14 and Figure 15.As shown in figure 16, Integral type heat-pipe heat exchanger is round adiabatic section 207 bendings of centre, and the form of this continuous loop pipeline is U-shaped layout 211.
Although in Figure 16 Figure 14 is bent to into U-shaped layout with the Integral type heat-pipe heat exchanger shown in Figure 15, unit-type heat exchanger can also be around middle adiabatic section 207, to any direction bending.As shown in Figure 16 A and Figure 16 B, Integral type heat-pipe heat exchanger can bend to L-type, or extends to different directions with 202 two parts 201, forms the form of a curve.
Figure 17 also is an Integral type heat-pipe heat exchanger, by the pipeline 200 shown in several and Figure 14 similarly continuously the loop pipelines form.In Integral type heat-pipe heat exchanger 205 ', continuously the non-snakelike parts in the loop pipeline 200 ' can be the forms of a straight tube 204 ', also can be bend pipes 204 " form.This Integral type heat-pipe heat exchanger also comprises the adiabatic section of a centre and the fin that can strengthen heat-transfer capability simultaneously.
Figure 18 is the form after continuous loop pipeline shown in Figure 14 is made amendment.Continuous loop pipeline 300 shown in Figure 18 is three dimensional form, and all pipelines are not to arrange in one plane as among Figure 15 and Figure 16.
Continuous sealing endless tube 300 among Figure 18 comprises a first 301 and second portion 302.According to the different arrangements of monolithic three-dimensional heat pipe exchanger 305 in the air channel, first 301 and second portion 302 can be respectively as evaporation ends or condensation end uses.The same with other above-mentioned Integral type heat-pipe heat exchangers, the Three Dimensional Thermal pipe in pipe among Figure 18 also comprises the adiabatic section 307 of a centre and the fin 306 that can strengthen heat-transfer capability.
Figure 18 A and 18B are the three-dimensional continuously side views of loop pipeline shown in Figure 18, and Figure 19 is top view.
Shown in Figure 20 is to use several, with three-dimensional continuously loop pipeline 300 similar pipelines among Figure 18, the monolithic three-dimensional heat pipe exchanger of composition.With pipeline 200,200 ' and pipeline 300 the same, the pipeline 300 ' among Figure 20 can make refrigerant mobile continuously in whole pipeline.The movement of refrigerant in pipeline is that the pressure of inside, tube road and the temperature difference of pipeline external are carried out.
Because each pipeline 200,200 ', 300,300 ' is a continuously return of sealing, some refrigerant all in running carries out complete circulation at whole pipe interior.In fact, refrigerant can move at whole pipe interior, is to carry out in the mode of infiltration by swabbing action.When Integral type heat-pipe heat exchanger is started working, when the part refrigerant moves at whole continuous loop pipe interior, each root straight tube in the serpentine coil such as the pipeline 320 among Figure 20, can move with the method for operation of the existing standard heat pipe shown in Fig. 1.
Continuous loop heat pipe among the present invention can overcome conventional heat pipe in use to the dependence of gravity, and is higher than evaporation ends because the height of condensation end of heat pipe does not need.Therefore, this continuous loop heat pipe can be installed in the front and back of surface cooler at an easy rate, or is installed in the airduct of existing air-conditioning system, thereby strengthens the dehumidifying effect of surface cooler.In addition, by utilizing Action of Gravity Field, and the continuous swabbing action of the refrigerant that forms of loop heat pipe, the heat pipe exchanger among the present invention is more much bigger than the heat-transfer capability of traditional heat pipe exchanger.
Figure 21 to Figure 23 be Integral type heat-pipe heat exchanger 405 with different directions, be installed in several modes between air-conditioning return air pipeline D1 and the air-supply pipeline D2.Because be the heat pipe of continuous loop, the mounting means of Integral type heat-pipe heat exchanger 405 in airduct, the actual motion of opposite heat tube is inessential, this is because heat pipe of the present invention does not need gravity when work.No matter in which kind of mode arrange, Integral type heat-pipe heat exchanger 405 can use the continuous loop pipeline 200 shown in Figure 14, also can use the three-dimensional continuously loop pipeline 300 shown in Figure 18.
No matter be which kind of above-mentioned mode, the loop pipeline all comprises a first 401 and second portion 402 continuously.As shown in Figure 21, first 401 is installed among the backwind tube D1, as a whole the evaporation ends of formula heat pipe exchanger 405; Second portion 402 is installed among the ajutage D2, as a whole formula heat pipe exchanger 405 condensation ends.
Figure 21 is the version that airduct is arranged up and down, and Figure 22 is the installation form of heat pipe exchanger 405 in the tile vertically airduct.
Figure 23 is the installation form of heat pipe exchanger 405 in the horizontal Tile airduct.Because used continuous loop pipeline in heat exchanger 405, heat pipe exchanger no longer relies on the discrepancy in elevation at two ends when work, and heat pipe exchanger just can be such as shown in Figure 23 so, is installed in the airduct of horizontal Tile.The layout of the continuous loop pipeline in the heat pipe exchanger 405, the mode among similar and Figure 14 and Figure 18.
Owing to having used continuous loop pipeline, heat pipe exchanger both can be installed in the airduct of tile vertically, also had in the airduct that is installed in horizontal Tile.
Figure 14 has realized one of them purpose that the present invention will reach to the described continuous loop heat pipe for Integral type heat-pipe heat exchanger of Figure 23.Continuous loop pipeline and refrigerant have been used in this implementation method.When this pipeline is used as the heat pipe use, the swabbing action that pipe interior pressure reduction produces will make refrigerant flow at whole continuous loop pipe interior.In fact refrigerant is the mode of permeating, and is forced through whole pipeline.Because refrigerant is forced through whole pipeline, so the caliber of heat pipe is compared with the caliber of conventional heat pipe, that can do is less.This shows, used the heat pipe exchanger of continuous loop pipeline, produce and get up to become very simple, and on installation form, also do not relying on action of gravitation.By the present invention, can realize that performance is better, more easily heat pipe exchanger is installed.
Need to prove, used the heat pipe of continuous loop pipeline among the present invention, its application is not limited in those aspects described in the most preferred embodiment, and the other field that need to use heat pipe can.Such as the claim in the annex, under the prerequisite of the spirit and scope of the invention, can to the form of expression of invention most preferred embodiment, carry out various modifications and improvement.
