Description
Technical field
The present invention relates to the design and manufacturing process of a kind of heat exchange ultramicropore pipe.
Background technology
So far, it is domestic, international to produce product mesh in aluminium alloy pressure processing industry, the extruding of aluminium alloy micropore flat tube
The minimum more micropore flat tubes of the preceding representative outer profile size that can be produced in the industry are 10 × 1mm, and its micropore wall thickness is
The micropore flat tube that 0.16mm, single pore size reach 1 × 0.64mm, micropore quantity is 8, but production cost reaches tens thousand of first people
As many as coin, and Life of Die for Extruding Aluminium Alloy be difficult maintain and product price be difficult to be received by user.Current international, domestic aluminium alloy
Pressure processing industry, still it is difficult the micropore for producing theoretical equivalence diameter ＜ 1.0mm corresponding to single hole equivalent aera, is also difficult life
If its equivalent diameter of output is 1.0mm, actual micropore perimeter L mm is also L=N π much larger than theoretical 1 × π of girth mm several times
mm（N ＞ 8）The micropore of feature, it more difficult to produce the micropore of micropore height h≤0.5mm sizes；It can not also produce simultaneously when single
Individual micropore reach when 1 × 0.64mm and micropore quantity are 100 or more or multiple micropores, its outer wall thickness be 10mm even more
Thick micropore heavy wall flat tube product.
In evaporator for motor vehicle air conditioner, condenser manufacturing field, the use of aluminium alloy micropore flat tube is in the field of business general already
And；But with microelectronic industry or server category, wireless telecommunications class, big data class, high power laser diode class industry it is fast
Speed development, the micropore equivalent diameter of urgent need is smaller, micropore inwall girth is longer, micropore height dimension is smaller or even in 0.3mm, wall
Micropore flat tube that thickness can reach more than 5mm, that flat tube width is badly in need of up to more than 60mm industry can be also known as micropore cold drawing
Press worked product, in the industry cycle there is no method to produce so far；Industry can only be formed micro- logical by accurate mach mode at present
Road, be then welded using large area friction welding (FW) with another block of aluminium sheet, so, micropore can not it is smaller, arrangement it is more dense and compared with
Difficulty reaches the demand of user.And it is expensive with environmentally friendly refrigerant class refrigeration working medium, with greater need for the spatial volume of microchannel cavity
To small micro- trend development, product cost is then reduced to reduce the dosage of refrigerant.
Based on above-mentioned analysis, the present invention relates to a kind of heat exchange corresponding to the design and manufacturing process of ultramicropore pipe ultra micro
Passage product, it not only can preferably solve the demand of industry, can fill up the product blank of industry, meet the need of downstream industry
Ask, also widened the ultra micro tube channel of various varying cross-section features and the industry use range of flat tube simultaneously.
The content of the invention
For overcome the deficiencies in the prior art, the present invention provides a kind of intelligent flat formula highly-efficient solar collecting device
The technical solution adopted for the present invention to solve the technical problems is：The design and system of a kind of heat exchange ultramicropore pipe
Make technique；Wherein the outline of ultramicropore pipe is such as：The design of wavy, the even any character of rectangle, rectangle, its design principle
It is to exchange for cause heat exchange medium fluid to produce turbulent flowing as far as possible with smaller fluid resistance, in the hope of larger heat
Exchange efficiency；And the design of the inner chamber contour line geometry character of each micropore, whether rectangle or rectangle side wall it is multiple tooth,
Or different form, its design principle works as the inner chamber area S ㎡ of single micropore equivalent diameter Dmm mono- regularly, corresponding to diameter Dmm
Inwall perimeter L mm be also heat-exchange working medium wetted perimeter on the premise of flow resistance is reduced as much as possible, in the micropore provided by design
Wall perimeter Lmm be greater than the π D of the L of equivalent diameter Dmm theoretical girth corresponding to the cross-sectional area S ㎡ of micropore inner chamber=4 and
More than；It is thick that it is directly reduced using cold-drawing process after foregoing ultramicropore pipe or flat tube are molded by extrusion die pressure processing
Spend H values, you can form ultramicropore tubing products.
As the improvement of above-mentioned technical proposal, the design and manufacturing process of a kind of described heat exchange ultramicropore flat tube,
The finished product after blank design and stretching including the outline of ultramicropore pipe 1, its blank can only surpass along height H direction ratios
The height of microporous pipe is big, and the design value likelihood ratio is generally 1.20-1.35 times；And the outline geometry character of ultramicropore pipe is set
Count principle, be when outer contour surface of the heat-exchange fluid medium by ultramicropore pipe, its can smaller fluid resistance exchange for
As far as possible so that heat exchange medium fluid produces turbulent flowing, in the hope of the larger heat exchanger effectiveness of single ultramicropore pipe 1.
Further, the design and manufacturing process of a kind of described heat exchange ultramicropore flat tube, including ultramicropore pipe
Outline blank design and stretching after finished product, when its blank outline is designed as a, b, c, a, b, c tri- in blank
The design of the height H values of kind different type product is high according to the extensibility of aluminum alloy materials and the finished product outline wall of ultramicropore pipe
If degree be designed as H1 values, be typically designed value be H1=（1.25-1.55）H, a, b, c in its blank are after mould drawing
Each position height of product outline and outline geometry can reach H values and set character, and now micropore endoporus height h can
20%-50% is reduced, its micropore equivalent diameter is up to micron order；, can because its micropore equivalent diameter is post-processed by drawing process
