In Fig. 4 (A), the oblique stripe 2a of section, the 2b of the convex of formation V word shape forms symmetrical angle with respect to the center of air stream 5.That is, with respect to the center line of air stream 5, the oblique stripe 2a of section in left side is angle α, and the oblique stripe 2b of section on right side is negative angle α.
Patent documentation: WO2008/090872A1 communique
The present inventor has confirmed four swirl stabilization of the equalization of Fig. 4 (B) by experiment, easily be detained dust or coal etc. on the border of its adjacent eddy current, and they can rise to a certain degree.The circulating resistance that adheres to air stream because of this particle-like substance increases as can be known, thereby heat exchange performance reduces.
Summary of the invention
Therefore, in the present invention, find to reduce as far as possible the condition of the delay of particle-like substance in the wave-shaped fins of a plurality of convex shaped parts with such V word shape or W word shape by various experiments, and complete the present invention based on this opinion.
a first aspect of the present invention is heat exchanger, they are between a plurality of flat tubes (1) arranged side by side or be fixed with a plurality of fins (2) in this flat tube, and the gas that contains particle-like substance is logical at this fin (2) effluent, this fin (2) goes out the cross section of circulating direction as a plurality of V brief note sections (9) of waveform take plane V word shape or the bending of the word of falling V shape respectively towards the circulating direction of described gas, described heat exchanger is characterised in that, in first plane (4) of this fin, consist of the pair of angled bar (2a of section of this V word, a side (2a) 2b) with respect to the circulating direction of described gas to positive side tilt alpha angle configurations, the opposing party (2b) with respect to the circulating direction of described gas to minus side inclination β angle configurations, thereby the two oblique stripe (2a of section, 2b) be configured to asymmetry angle with respect to this circulating direction, with this opposed second plane, the first plane (4) (3) in, become the asymmetry angle opposite with the first plane (4), a described side's oblique stripe section (2a) with respect to the circulating direction of gas to just rolling oblique β angle configurations, the opposing party (2b) with respect to the circulating direction of described gas to minus side tilt alpha angle configurations.
A second aspect of the present invention is on the basis of first aspect, wherein, the open angle of the V brief note section (9) of this fin is 40 degree～90 degree, and the difference of the described α angle of this a pair of oblique stripe section (2a, 2b) and the absolute value of described β angle forms 3 degree～15 degree.
A third aspect of the present invention is on the basis of first aspect or second aspect, wherein, the metallic plate Integral bending is become waveform and consists of fin (2), only be formed with described V brief note section (9) on the plane in noncontact fin (2) and flat tube (1) section, only be formed with a V brief note section (9) on the amplitude direction of the waveform of fin, and be formed with smooth face (8) between the two ends of two edges of the amplitude direction on this plane and V brief note section (9), the edge of this two edge engages with flat tube (1).
[invention effect]
In the heat exchanger of a first aspect of the present invention, a plurality of a pair of the oblique stripe 2a of section, the 2b of the V-arrangement of its fin 2 form the asymmetrical angle in left and right towards air stream 5 in the first plane 4, and with opposed the second plane 3, the first plane 4 in, form asymmetric with the first plane 4 heterochiral angles.Thus, in each fin section, two little eddy current 7 of two maelstroms 6 of large radius of turn and little radius of turn form respectively helical form.And each eddy current interacts, and repeatedly carries out hybrid separation, and the lip-deep particle-like substance that is attached to fin 2 is blown out, and stops up few heat exchanger thereby form eyelet.
This be at gas along each oblique stripe 2a of section of the four direction of each section 12 that is positioned at fin 2, when 2b moves, postpartum four spiral vortex.Yet, in the little oblique stripe section in angle of inclination, because the oblique stripe section that its circulating resistance is larger than the angle of inclination is little, therefore produce the impetus well and larger eddy current.
Consequently, in each fin section, two eddy current of two eddy current of large radius of turn and little radius of turn form respectively helical form.And the direction of rotation of two eddy current that the large impetus is good is identical, and four eddy current is big or small unbalanced, therefore they interacts, eddy current each other is hybrid separation repeatedly, thereby indirectly pats the fin surface each several part, prevents adhering to of particle-like substance.Therefore, as construction implement etc. in the situation that the cooler for recycled exhaust gas that the heat exchanger that use in dust many places or the exhaust that contains coal are circulated have the eyelet that prevents fin and stop up, thereby become the effect that makes the heat exchanger that initial performance continues.
And in the fin of heat exchanger of the present invention, no matter for forward or backwards, its circulating resistance is all roughly the same, even therefore change the direction of a part of fin, also has equal performance with respect to this V brief note section for the circulating direction of air stream.Even mistake the direction of fin, also no problem, and manufacturing management is easy.
According to a second aspect of the invention, also become the good heat exchanger of heat exchange performance.This is because the structure of a second aspect of the present invention is the optimum condition of the heat exchanger of horizontal V ripple fin.
That is the fin efficiency when, the open angle of V word is spent for 40 degree～90 centered by 60 about degree is maximum.When the open angle of V word is above and 40 degree of 90 degree when following, represent that the J/f of fin efficiency sharply descends.Therefore, but efficiency of selection good 40 the degree～90 the degree.
And the difference of the asymmetric angle of the left and right in the angle of V word is compared with symmetric figure V fin in the scope of 3 degree～15 degree, and fin efficiency synthetically improves.That is, in this scope, compare with symmetric figure V fin, with interior minimizing, and circulating resistance significantly is reduced to 20% left and right, consequently, can provide a kind of air blast power little energy-saving heat exchanger with respect to heet transfer rate several % slightly.
Be 3 degree when following at differential seat angle, gross examination of skeletal muscle is less than energy-saving effect.And, when following, can not expect the reduction of circulating resistance at 3 degree, and also not prevent eyelet obstruction effect.In addition, when spending over 15, heet transfer rate significantly reduces.
In a third aspect of the present invention, be formed with smooth facially 8 between the two ends due to the two edges of the amplitude direction in the plane of fin 2 and V brief note section 9, and the edge of this two edge engages with flat tube 1, therefore this smooth facial 8 bight that is positioned at fin.Therefore the circulating resistance of this part reduces, thereby can prevent that particle-like substance from accumulating in each bight of fin.

The specific embodiment
Then, based on accompanying drawing, embodiments of the present invention are described.
Fig. 1 is the key diagram of wave-shaped fins of the present invention, is (A) its three-dimensional sketch, is (B) top view on first plane 4 of (A), is (C) top view on second plane 3 of (A).In addition, Fig. 2 (A) is the major part stereogram of heat exchanger, is (B) that its B-B is to looking cutaway view.
As shown in Fig. 2 (A), in this routine heat exchanger, contact respectively the fin 2 that is fixed with waveform between a plurality of flat tubes 1 arranged side by side.In this example, it is wavy that fin 2 integrally bendings form rectangle, and flat tube 1 is fixed in the top of the bending of fin 2 and the soldering of paddy section.And, there are the first smooth plane 4 and second plane 3 opposed with it between this top and paddy section, on each plane 3,4 along air stream 5 directions and the V brief note section 9 that shows a plurality of V word shapes that become respectively gradually expansion towards this air stream 5, as shown in Fig. 2 (B), the cross section of V brief note section 9 (cross sections of air stream 5 directions) is bent to form and is little waveform, and its longitudinal section (with the cross section of air stream 5 orthogonal directions) is bent to form and is less waveform.
And the width of each V brief note section 9 forms more smaller than the amplitude of fin 2, as shown in Fig. 1 (A), (B), is formed with smooth facial 8 between the top of the two ends of V brief note section 9 and ripple and bottom.
And, the oblique stripe 2a of section of a side in the pair of angled bar 2a of section, the 2b that consist of the V word in this first plane 4 of each V brief note section 9 is positioned at the α angle (with left for just) of positive side with respect to the circulating direction of air stream 5, the opposing party's the oblique stripe 2b of section is formed on minus side with the β angle.Thus, the two oblique stripe 2a of section, 2b form the left and right asymmetry angle with respect to center line.And, with opposed the second plane 3, this first plane 4 in, form the left and right asymmetry angle opposite with the first plane 4.That is, in the second plane 3, the oblique stripe 2a of section in left side with respect to the circulating direction of gas to just rolling oblique β angle configurations, the oblique stripe 2b of section on right side with respect to the circulating direction of gas to minus side tilt alpha angle configurations.
In order to form such fin 2, as shown in Fig. 1 (A), form the left and right asymmetrical V brief note section group of same shape with the fixed intervals punching press on the plane of strip metal plate.Then, it is bent into square wave or V-character wave shape.Consequently, as shown in Fig. 1 (B), (C), on opposed plane 3,4, become that the left and right is asymmetric and this is asymmetric reverse each other.
According to experiment, by the first plane 4 and the second plane 3 being formed the oblique stripe section of reverse each other asymmetric angle, thereby as shown in Figure 1, 2, when air stream 5 is circulated as arrow, as shown in Figure 3, form two maelstroms 6 and two little eddy current 7 on the diagonal in the section 12 (space that flat tube 1 and the first plane 4, the second plane 3 surround) of each fin.
This phenomenon can be speculated as based on following reason.
This is at gas during along each oblique stripe 2a of section, the oblique stripe 2b of section of the four direction of the section 12 that is positioned at fin 2 circulation, in the little oblique stripe section in angle of inclination, the oblique stripe section circulating resistance larger than the angle of inclination is little, and therefore the impetus produces eddy current well more.And little oblique stripe section produces maelstrom 6 at this angle of inclination, and the part beyond it produces little eddy current 7.A pair of maelstrom 6 forms in the same direction, and both easily collaborate because the impetus is large.This maelstrom 6 is affected by little eddy current 7 also, and repeatedly carries out the interflow separation of eddy current.
Consequently, in each section 12 of fin 2, eddy current changes with the space in time, consequently, effectively blows out easily accumulating in the top of fin and the particle-like substance of paddy section.
On the other hand; in the situation that the fin 2 shown in Fig. 4 (A); when the oblique stripe 2a of section, the oblique stripe 2b of section are symmetrical α with respect to air stream 5; as shown in Fig. 4 (B); eddy current 10 presents four equably; therefore they are very stable, are formed with delay section 11 on their border, easily accumulate the particle-like substances such as dust or coal in this delay section 11.
Then, to the open angle of the V brief note section 9 on the plane of fin 2, be that the optimum range of alpha+beta in Fig. 1 (child's hair twisted in a knot-childhood) is narrated.Fig. 5 represents that the difference of absolute value of each angle of the asymmetrical α in left and right and β is 9 degree and the optimum range the when child's hair twisted in a knot-childhood is changed.And, adopt the child's hair twisted in a knot-childhood at transverse axis, adopt J/f at the longitudinal axis.
This J/f is the balanced efficient of considering heet transfer rate with the air drag of fin.At this, J is the Colborn factor, and f is resistance coefficient.
J＝St·Pr
2/3
St＝Nu/(Re·Pr)
Re=Reynolds number Pr=Prandtl number Nu=slave Sai Er number
Wind speed be 3m/s～30m/s during test, confirmed by experiment the child's hair twisted in a knot-childhood with respect to the maximal efficiency under each wind speed, and how efficient reduces due to the variation of this child's hair twisted in a knot-childhood.
Consequently, as can be known under any wind speed during the child's hair twisted in a knot-childhood of 60 degree～65 degree efficient maximum.And as can be known, when the child's hair twisted in a knot-childhood of 40 degree～90 degree, under any wind speed, with respect to maximum, efficient exists 3% with interior reduction.
Therefore, the child's hair twisted in a knot-childhood of the employing of the fin in heat exchanger of the present invention V word is the fins of 40 degree～90 degree.
Then, Fig. 6 is to be the figure of optimum value of the differential seat angle of obtaining α and β at 60 o'clock of maximal efficiency in the child's hair twisted in a knot-childhood.Transverse axis adopts differential seat angle, the heet transfer rate α that longitudinal axis employing is obtained by experiment and the pressure loss Δ P of fin.
Wind speed shown in this figure is the situation of 10m/s, 1m/s.
The result of experiment is that as shown in Figure 6, in the situation that differential seat angle is spent less than 3, under any wind speed, heet transfer rate α and pressure loss Δ P do not have to change.And when being 3 degree when above, heet transfer rate reduces, and the pressure loss reduces.When differential seat angle was spent over 15, under any wind speed, heet transfer rate α sharply descended.
In the situation that differential seat angle is 15 degree, when wind speed was 10m/s, heet transfer rate α was 0 to reduce by 2% with respect to differential seat angle.At this moment, the pressure loss is 0 to reduce by 20% with respect to differential seat angle.In differential seat angle was the scope of 3 degree～15 degree, the reduction of the pressure loss was mostly more than the reduction of heet transfer rate as can be known for this situation.
Therefore, when wind speed is 10m/s, if differential seat angle is the scopes of 3 degree～15 degree, with respect to the minimizing (2%) of slightly heet transfer rate, can access the reduction (20%) of the large pressure loss., can significantly reduce the air blast power of heat exchanger, thereby can improve the overall efficiency of heat exchanger during as the fin of heat exchanger when the fin that adopts such differential seat angle.
Equally when wind speed is 1m/s, in the situation that differential seat angle is 3 degree～15 degree, the reduction (1%) with respect to slightly heet transfer rate also can access the minimizing (19%) of the large pressure loss.
Wind speed is that the situation of 20m/s and situation that wind speed is 30m/s also show same result.At this, in the present invention, the open angle of the V brief note section 9 of fin is 40 degree～90 degree, and the difference of the α angle of the oblique stripe 2a of section, the oblique stripe 2b of section and the absolute value of β angle is that 3 degree～15 are spent.
Then, with respect to V brief note section 9, the direction of air stream 5 is changed over forward and oppositely, measure the pressure loss separately.This experimental result shown in Figure 7.The transverse axis of Fig. 7 represents wind speed v (m/s), and the longitudinal axis represents pressure loss Δ P.And, as fin, the fin of symmetric form shown in Figure 4 and of the present invention asymmetric fin shown in Figure 1 are compared.
At this moment, symmetric form and asymmetric child's hair twisted in a knot-childhood are all 60 degree.
The solid line of the topmost in figure means that V brief note section 9 forms the situation of widening gradually along the direction of air stream 5, with it as forward.And, it is opposite to reverse.
The situation of V brief note section 9 left-right symmetry and forward is with respect to wind speed and the pressure loss is the highest.The pressure loss second high or the left-right symmetry type, but be reverse V brief note section 9.Pressure loss third high be asymmetric and forward as object of the present invention.Minimum is of the present invention asymmetric and reverse.
As shown in Figure 7, in the situation that the fin of heat exchanger of the present invention is asymmetric, almost do not have with respect to the pressure loss of the air stream 5 of forward with respect to the difference of the reverse pressure loss.Even this means the direction of mistaking fin 2 or mistake the direction of a part of fin 2, heat exchange performance also reduces hardly.
On the other hand, in the situation that symmetric form, V brief note section's 9 situations are set and differ greatly along the V brief note section 9 situation pressure losses oppositely are set along forward with respect to air stream 5.Therefore, mistake its direction and show large performance change.
Then, Fig. 8 means and makes high temperature fluid at the figure of the interior circulation of flat tube 1 and air stream Temperature Distribution of its flow direction port of export when fin 2 effluents are logical of making normal temperature.And, be (A) situation of having used the asymmetric fin 2 in the left and right of heat exchanger of the present invention shown in Figure 1, (B) be the example that has used the fin 2 of left-right symmetry type shown in Figure 4.
According to this high temperature contour as can be known, the scope of high-temperature 13 is less than the scope of the high-temperature of Fig. 4 in the present invention.The heat exchanger effectiveness that this means fin of the present invention is high.
In the above-described embodiment, fin is configured in the outer surface of flat tube, but also can fin be configured in to its change the inner surface of flat tube.In addition, it is orthogonal wavy that fin both can Integral bending, also can be bent into triangle wavy.
