Detailed description of the invention
Before any embodiments of the invention are explained in detail, that application of the present invention is not limited to set forth in the following description or illustrated piece construction and layout in the accompanying drawings details is to be understood that.The present invention can have other embodiments, and can realize in many ways or implement.And, be to be understood that wording as used herein and term are for illustrative purposes, should do not think restriction." comprising ", " comprising " herein or the use of " having " and version thereof are intended to comprise thereafter listed item and equivalent item thereof and addition Item.Unless carried out specifying or limiting, otherwise term " installation ", " connection ", " support " and " coupling " and version thereof are briefly carried out using and containing directly with indirectly installing, be connected, support and be coupled.In addition, " connection " and " coupling " be not limited to physics or the connection of machinery or coupling.
Tube Sheet of Heat Exchanger assembly 1 according to the embodiment of the present invention has been shown in Fig. 1 to 5.This pipe assembly 1 can be used as one in the multiple independent pipe of the heat exchanger (such as radiator) in the jumboes such as such as excavator, mining truck, generating set (gen-set).But, should be understood that pipe assembly 1 can be used in the heat exchanger of polytype and size.
Pipe assembly 1 comprises pipe 2, and pipe 2 extends to the second end 8 from first end 7.Pipe 2 defines fluid flow conduits, can transmit fluid (such as, engine coolant) thus by pipe assembly 1.As an example, pipe assembly 1 can be used in engine coolant radiator, thus to flow to another and the used heat removed from this engine coolant stream in end 7,8 through pipe 2 from end 7,8 along with engine coolant stream.
Pipe 2 comprises the flat sections 3 between end 7,8.Flat sections 3 (illustrating with reference to Figure 11 best) comprises the first and second parallel, wide and smooth sides 12.Wide and smooth side 12 is spaced apart from each other, and is linked by two relative, isolated, narrow pipe sides 15.Although the profile showing narrow pipe side 15 is in the exemplary embodiment arc, in other embodiments, narrow pipe side 15 can be straight, or they can have certain other contour shapes.Two wide and smooth sides 12 and two narrow sides 15 together define the continuous print tube wall 25 of fluid flow conduits, wherein in order to make fluid be flowed by pipe 2, in continuous print tube wall 25, define open space.Although in the exemplary embodiment without any display, but surface enhancement features or turbulent feature (flow turbulationfeatures) are preferably provided in some cases in conduit, thus improve by the coefficient of overall heat transmission between the fluid of pipe 2 and tube wall 25.
Continue with reference to Figure 11, the flat sections 3 of pipe 2 has pipe time size (minor dimension) d1 and major dimension (major dimension) d2, pipe time dimension definitions is the distance between the surface outwardly of two wide and smooth sides 12, and pipe major dimension is defined as the distance between the outermost point of two narrow sides 15.In some extremely preferred embodiment, major dimension d2 is than secondary size d1 several times greatly.Exemplarily, larger than secondary size nine times of the major dimension in exemplary embodiment.
Pipe assembly 1 also comprises two the takeup type fin structures 10 arranged along flat sections 3.Fin structure 10 comprises the multiple flank section (flank) 16 be connected in an alternating manner with valley 17 by peak portion 18, makes each fin structure 10 be near sinusoidal shape (being best viewed in Fig. 3).Fin structure 10 can be general type, and as shown in Figure 3, or they can comprise supplementary features, to improve heat trnasfer, structural strength, durability or its combination.By way of example, in certain embodiments, fin structure 10 can comprise shutter, protuberance, slit, otch or knownly be used for improving the heat trnasfer of flank section 16 and/or other features of the rigidity of structure.In other embodiments, edge ruffle can be provided at the one or both ends place of the narrow pipe side 15 of the vicinity of fin structure 10.Such edge ruffle is particularly conducive to be provided may due to stone or the shock of other chips and the tolerance of the damage caused.
Thin side plate 11 is also comprised in pipe assembly 1.These side plates 11 are parallel to the relative wide and smooth side 12 of pipe 2, and either side by fin structure 10 with relative wide and smooth side 12 equi-spaced apart of pipe 2.Therefore, the flank section 16 of fin structure 11, peak portion 18 and valley 17 provide multiple thin web with by spaced apart to side plate 11 and continuous print tube wall 25.Side plate 11 is general plane types, but can comprise the feature of such as curved edge, thus provides the rigidity of enhancing and/or contribute to assembling.
Space between flank section 16 provides circulation road, to make fluid and to be in heat transfer relation by the fluid of pipe 2, makes it possible to heat exchange between two fluids.Exemplarily, boot environment air can be carried out by circulation road, thus the engine sleeve pipe cooling agent by pipe 2 is cooled.But, should be understood that, can utilize pipe assembly 1 that other various fluids are in heat transfer relation.Each circulation road between flank section 16 limits by one of valley 17 and peak portion 18 and by one of the flattened side 12 of pipe 2 and the side plate 11 of general plane type further.By abundant restricted circulation road by this way, prevent by the too early leaving channel of the fluid of those passages, thus improve heat-transfer capability.
Pipe 2, fin structure 10 and side plate 11 are preferably combined together to form monolithic construction, thus provide the good thermo-contact between the fluid that is in heat transfer relation, and good structural intergrity.Although various material can be used to construct pipe assembly 1, in extremely preferred embodiment, pipe 2, fin structure 10 and side plate 11 are formed by the metal of the such as high thermal conductivity such as aluminium, copper.Can by comprising soldering, parts combine and form pipe assembly 1 by solder, the kinds of processes such as gluing.
In order to promote the good heat trnasfer between fluid, advantageously fin structure 10 and side plate 11 extend on the whole major dimension d2 of flat sections 3.In some cases, may preferably make fin structure 10 and side plate 11 extend slightly beyond the outward flange of narrow pipe side 15, thus protection fluid flow conduits is damaged from the shock due to stone or other chips.
Have been found that comprise even very thin side plate 11 can significantly reinforced pipe assembly 1, particularly just about with regard to the bending of the centroidal axis in pipe major dimension d2.Fin structure 10 provides minimum rigidity in the direction in which due to its winding essence, makes when not having side plate 11, and continuous tube wall 25 provides unique to about the bending tolerance of this centroidal axis.Due to the relatively little secondary size d1 of smooth pipeline section 3, by means of only continuous tube wall 25 realize quite little to the tolerance bending about this centroidal axis, and side plate 11 and the spaced apart distance much larger than secondary size d1 of this centroidal axis provide the beneficial effect of essence.
By the barycenter the moment of inertia of this axis about pipe assembly 1 and the barycenter the moment of inertia being only pipe 2 are compared, side plate 11 can be quantized (except keeping the skew of the flattened side 12 of side plate 11 and pipe 2, can think that fin structure 10 pairs of barycenter the moment of inertias are inoperative) the impact of pipe assembly 1 about the bending stiffness of the centroidal axis in pipe major dimension d2.For the exemplary embodiment of major dimension with the pipe thickness of 0.8mm, the side plate thickness of 0.25mm, the fin structure height of 6.55mm, the secondary size of 3.7mm and 23.27mm, for pipe assembly and only have Guan Eryan, the barycenter the moment of inertia calculated about pipe major dimension axis is respectively 925mm
4and 76mm
4.In other words, pipe assembly is approximately the twelvefold of the barycenter the moment of inertia of pipe itself about the barycenter the moment of inertia of pipe major dimension axis.In a preferred embodiment, pipe assembly is at least five times of the barycenter the moment of inertia of pipe itself about the barycenter the moment of inertia of pipe major dimension axis, in highly preferred embodiment, is at least ten times.When pipe 2 is made up of the material (such as, aluminium alloy) with relatively low elastic modelling quantity, be particularly preferred like this.
The pipe 2 of exemplary embodiment comprises the first cylindrical portion 4 of contiguous first end 7 and the second cylindrical portion 5 of contiguous second end 8 further, and flat sections 3 is arranged between the first cylindrical portion and the second cylindrical portion.These cylindrical portion 4,5 make pipe assembly 1 can insert in the storage packing ring be arranged in the opposed collector (not shown) of heat exchanger reliably, No leakage.In order to make the pipe amount that can be used for available heat transmission maximize, the length of post ends section preferably remains minimum, and the length of flat sections 3 is preferably more than 90% of the total length of pipe 2.In the cylindrical portion 5 of exemplary embodiment, provide circumferential pearl 9, thus vertically ought be arranged in moving down of time limit tubulation assembly 1 in heat exchanger.
Although embodiment illustrated in the accompanying drawings comprises the post ends section being positioned at pipe two ends place, should be understood that, in some cases, pipe assembly 1 can not be provided with in post ends section 4,5 one or two.When not comprising such post ends section, corresponding storage packing ring can be provided with the storage opening of the profile corresponding to the continuous tube wall 25 in flat sections 3.
In some preferred embodiment of the present invention, make Tube Sheet of Heat Exchanger assembly 1 by forming soldered fitting between aluminum pipe 2, first and second Aluminum corrugate fin structure 10 and the first and second aluminum side plates 11.First corrugated fin structure 10 is arranged between the first wide and smooth side 12 of the first side plate 11 and pipe 2, and the second corrugated fin structure 10 is arranged between the second wide and smooth side 12 of the second side plate 11 and pipe 2.This assembly is compressed, thus makes the peak portion 18 of fin structure 10 and valley 17 and adjacent part contact, thus can form soldered fitting at contact point place.
There is fusion temperature be used for forming soldered fitting lower than the solder of the fusion temperature of pipe 2, fin structure 10 and side plate 11.This filling metal is generally aluminium, is added with a small amount of other elements (such as silicon, copper, magnesium and zinc) to reduce fusion temperature.Solder can be provided as the coating on one or more parts to be brazed valuably.In certain embodiments, being used for the two sides of the sheet material forming corrugated fin structure 10 all scribbles solder, thus expect to have soldered fitting the place of having point of contact required solder is all provided, avoid not needing or undesirably having the position of joint to have solder simultaneously.
Although multiple method can be used to carry out the temperature of riser 2, fin structure 10 and side plate 11 thus make solder melt and form soldered fitting, two kinds of particularly preferred methods are vacuum brazing and controlled atmosphere soldering.In vacuum brazing, the part of assembling is placed in Sealing furnace and removes substantially whole air, thus forms vacuum environment.In this process, being present in magnesium in alloy along with part is discharged by heating, and plays the effect destroying the oxide layer be present on the outer surface of parts, and the solder making fusing is combined with the aluminium exposed.Owing to there is not oxygen in vacuum environment, thus prevent from again forming oxide layer, and prevent oxide layer from hindering metallurgical binding.
In controlled atmosphere soldering, apply solder flux to parts before heating.The heating of part betides in inert gas environment, thus prevents from again forming oxide layer after solder flux reacts and is present in the oxide layer displacement on the matching surface of part.Along with oxide layer displacement, the solder of fusing is combined with the aluminium exposed, thus forms soldered fitting.
Particularly preferably be, the multiple pipe assembly 1 of a soldering, thus improve the output in production and manufacturing environment.Fig. 6 shows the method according to the embodiment of the present invention, wherein makes four pipe assemblies 1 simultaneously.Should be appreciated that Same Way can be used for producing once more than four or be less than the pipe assembly of four.
In the embodiment in fig 6, the side plate 11 of pipe 2, corrugated fin structure 10 and general plane type is provided with.Each pipe 2 is arranged between paired corrugated fin structure 10, and each corrugated fin structure 10 is arranged between a pipe 2 and the side plate 11 of a general plane type.Demarcation strip 19 is arranged between the side plate 11 of the general plane type of phase adjacency pair.The side plate 11 of pipe 2, corrugated fin structure 10 and general plane type is arranged in lamination 26.Additional demarcation strip 19 is arranged to the contiguous side plate 11 being positioned at the general plane type at the outermost end place of lamination 26, and apply compression load to lamination 26 in the stacking direction, thus the peak portion 18 of takeup type fin structure and valley 17 are contacted with the wide and smooth side 12 of adjacent side plate 11 and pipe 2.
In order to provide uniform compression load to lamination 26, the bar 21 (such as, structural steel shape passage) with high rigidity can be used in the outermost end of lamination 26.By being used on multiple position around after metal tape 22 pairs of laminations of lamination 26 are applied with compression load, compression load can be kept.While compression lamination 26, bar 21 is tightened band 22, thus the tension force of band 22 keeps described compression load.After so assembling, lamination 26 is placed in soldering oven to form each pipe assembly 1.Lamination 26 is heated to the temperature being suitable for melting solder in stove, is after this cooled by lamination 26, thus the solder of fusing is solidified again, form soldered fitting thus at contact point place.After cooling, can remove from demarcation strip 19 each pipe assembly 1 be soldered to each monolithic construction.Demarcation strip 19 can be provided with coating to prevent any metallurgical binding between demarcation strip 19 and side plate 11, even if otherwise also can there is less desirable combination under brazing temperature when there is not solder.
Along with lamination 26 is heated to brazing temperature, the thermal expansion of the metal material in lamination 26 will occur.In aluminium soldering, parts are heated to the brazing temperature of 550 DEG C to 650 DEG C usually.This temperature range is more a lot of than being used for the temperature range of soldering copper parts, therefore when parts are aluminum with parts be in situation made of copper compared with, the thermal expansion experienced at the parts of cohesive process intermediate tube assembly 1 is much larger.
The present inventor has been found that and must to take care in brazing process to guarantee that fin structure 10 can not owing to being heated to brazing temperature and environment temperature and distortion are down in cooling.Be different from and relate to traditional brazed aluminum radiator manufacture that multi coil connects to monoblock type soldering core together with fin structure, the flank section 16 of fin structure 10 is easy to the distortion due to shearing force, and this shearing force is introduced by the thermal dilation difference between the parts of pipe assembly 1 and demarcation strip 19.In some embodiments of the invention, this problem improves by roughly being mated with the thermal coefficient of expansion of pipe 2, fin structure 10 and side plate 11 by the thermal coefficient of expansion of demarcation strip 19.This can by by similar aluminium alloy or form demarcation strip 19 by the another kind of material presenting similar coefficient of thermal expansion and realize.
Alternately, or additionally, multiple single demarcation strip 19 can be used between each adjacent pipe assembly 1, as shown in Figure 7.Gap 20 is provided between adjacent separating plate in the middle of each demarcation strip 19.When demarcation strip 19 is made up of (having the thermal coefficient of expansion that is different in essence with the thermal coefficient of expansion of the material making pipe 2, fin structure 10 and side plate 11) material, during lamination 26 heating and cooling, gap 20 can increase or reduce, thus alleviates in fact the distortion of the fin structure 10 that may cause due to the mismatch of thermal coefficient of expansion.Gap 20 act as the breach of the accumulation avoiding the distortion caused by thermal expansion, makes the discrete contact area that any such distortion is confined to below each single demarcation strip 19.When such as stainless more temperature-resistant material is used for demarcation strip 19 and the parts of pipe assembly 1 are made of aluminum, the assemble method shown in Fig. 7 will be useful especially.
Pipe 2 is discussed in more detail referring now to Fig. 8 to 13.As previously described, the embodiment of the pipe 2 shown in Fig. 8 comprises the smooth pipeline section 3 between the first cylindricality pipeline section 4 and the second cylindricality pipeline section 5.First cylindricality pipeline section 4 extends from the first end 7 of pipe 2, and the second cylindricality pipeline section 5 extends from the second end 8 of pipe 2.Between each in flat sections 3 and cylindrical portion 4 and 5 of transitional region 6.Transitional region 6 provides smoothly, continuous print flow path, so that fluid is by pipe 2, also avoid the position of mechanical stress concentration in tubing.
As the partial section in Figure 10 shows in detail, transitional region 6 extends past length L, span the position 14 from the position 27 of end 7 nearside of pipe 2 to end 7 distally.Length L preferably at least equals the diameter of post ends section 4, although in some optional embodiments, the size of this length is less than the diameter of corresponding end section.As shown in Figure 8, wide and smooth side 12 extends past the position 14 at either end place, with make wide and smooth side 12 at least partially along pipe 2 between the position 27 and position 14 of the starting point and terminal that define transitional region 6.
In a preferred embodiment, transitional region 6 defines curved path 13 with the infall of the wide and smooth side 12 in flattened tube region 3.These curved paths 13 provide the useful reinforcement of flat sections 3 relative to the bending moment about pipe major dimension axis of pipe 2.For comparison purposes, figure 9 illustrates the pipe 102 of prior art, comprise the flat sections 103 being linked to cylindrical portion 104 by changeover portion 106.The infall of transitional region 106 and flat sections 103 defines straight path 113 on the wide and smooth side 112 of flat sections 103.Straight path 113 extends in pipe major dimension, and is very easy to about the bending of major dimension axis.This is unfavorable especially in the process of installing from heat exchanger and/or remove the pipe assembly comprising pipe 102, because such bending moment is applied on pipe by such installation and such removing continually.When pipe is made up of the extremely low intensive material of such as annealed aluminium, this problem is especially aggravated.
The present inventor has been found that, crooked route 13 provides the significant stiffening effect of bending moment of opposing the above-mentioned type, and prevent pipe 2 or comprise pipe 2 pipe assembly 1 installation, remove and the flexing of pipe in other disposal process 2 or other of pipe 2 are damaged.Although can benefit from any nonlinear path, it is useful especially for limiting path 13 by the bow-shaped route section of a series of connection.
In the exemplary embodiment, each curved path 13 includes the top at the approximate center plane place being positioned at pipe, is positioned at along distance end 7 (when transitional regions are between flat sections 3 and the first post ends 4) to make this top or holds point 14 place on 8 (when transitional region is between flat sections 3 and the second post ends 5) path 13 farthest.Path 13 preferably includes the bow-shaped route section being positioned at top place, thus avoids the stress at top place to concentrate.
In some preferred embodiments, the outer perimeter of at least one (that is, circumference) in two cylindrical portion 4,5 is less than the outer perimeter of the continuous tube wall 25 in flat sections 3.This allows the relatively large heat transfer surface area in flat sections 3 on per unit length valuably, and without the need to holding the corresponding larger diameter at the one or both place in 7,8.The small diameter of end is preferred, because it can make the spacing of adjacent tubes assembly nearer and need less sealing surfaces at (such as) end place.In some preferred embodiments, the outer perimeter of flat sections 3 is more than the outer perimeter at least 25% of at least one in two post ends sections.
The heat exchanger comprising the fluid delivery tube over the whole length with flat profile is well known in the art, and employs many decades as radiator and analog.Usually one of the in two ways such flattened tube of structure.Flattened tube or to be extruded with even shape by blank of material and/or to stretch and be cut into discrete length, otherwise by sheet is formed as round-shaped, seam weldering, roller leveling become flattened tube shape and cut into discrete length of tube and formed by coiling sheet in tube mill.
When the pipe of the pipe 102 (Fig. 9) with flat sections 103 and post ends section 104 of such as prior art, the end of flattened tube is formed as cylindrical shape thus forms post ends section 104 and changeover portion 106.When pipe made by the material extremely strong by the malleability of such as copper, this operates rapidly and easily perform, and can only need the end forming pipe 2.But the method can not realize changeover portion 6 as described above.
By originally formed in flat sections 3 have the external diameter equal with the expectation outer perimeter of continuous tube wall 25, the pipe 2 of circular form, transitional region 6 can be formed.Then, concrete with reference to Figure 12, the diameter of the end of round tube 2 reduces to form post ends 4 and 5, and at the tapering transition zone 6' of end 4, maintenance original circular shape between 5 and central sections 3'.The reduction of this diameter can be realized by the swaged forging of such as tube end.In some preferred embodiments, end diameter reduces at least 20%, thus realizes the outer perimeter ratio of the expectation between flat sections 3 and post ends section 4,5.
As shown in figures 13 a and 13b, the profile of the flat sections 3 of pipe 2 can be limited by this part 3' forming pipe 2 between the first building form half portion 22 and the second building form half portion 23.When module is in an open position, that is, when two module half portion are separated from one another, as shown in FIG. 13A, pipe 2 is inserted between module half portion 22,23.By positioning pipe 2 like this, module closes thus is in the closing position shown in Figure 13 B, thus the flat sections 3 of pipe 2 is formed as time size d1 and major dimension d2.Optionally, in order to prevent flexing or other unexpected distortion of tube wall 12 wide and smooth in forming operation process, can being prepended in pipe 2 of forming operation in axle 24.After forming operation completes, used axle 24 can be removed from pipe 2.By comprising the geometry of complementary negative indication at the contact surface of module half portion 22 and 23, the geometry of transitional region 6 can be formed, thus in forming operation process, the geometry of the expectation of transitional region 6 is formed in pipe 2.
