Signified secondary fin is the first secondary fin.
The length of the first secondary fin is with shorter and shorter apart from the diagonal distance of main fin.
In the case that the length on foursquare side is certain, main fin and secondary fin are more long, then heat transfer effect is better in theory,
Found in process of the test, when main fin and secondary fin reach certain length, then heat transfer effect just increases and fails to understand very much
It is aobvious, it is primarily due to increase with main fin and secondary finned length, sink temperature is also become closer in the temperature of flight tip, with
Temperature reduction to a certain extent, then heat transfer effect can be caused unobvious, conversely also add the cost of material, meanwhile, heat exchange
During, if the spacing between secondary fin is too small, the deterioration of heat transfer effect is also easily caused, because with the increase of height,
Boundary layer is thickening, and boundary layer mutually coincides between causing adjacent fins, deteriorates heat transfer, and the spacing between secondary fin causes greatly very much to change
Hot area is reduced, and have impact on the transmission of heat, therefore distance, the foursquare length of side, the length of main fin in adjacent secondary fin
A size relationship for optimization is met between degree.
Therefore, the present invention is the optimal wing summed up by thousands of test datas of multiple various sizes of finned tubes
The dimensionally-optimised relation of piece pipe.
Angle between the secondary fin of described first and main fin is 45 °, and the distance of described adjacent secondary fin is L1,

Preferably, a=0.038, b=0.055.
It should be noted that adjacent pair fin apart from L1 be the distance counted since the center of secondary fin.
By being tested again after result of calculation, by calculating the numerical value on border and median, the result of gained is basic
Upper to be matched with formula, substantially within 2%, maximum relative error is no more than 3.5% to error, and mean error is 1.6%.
Compared with free convection, because shell and tube cooler has the coefficient of heat transfer higher, it is therefore desirable to finned tube
Finned length is fewer than in the case of free convection.Beer cooling can also so be met, but also material and space can be saved,
The amount of cooling water of unit mass higher is reached, more preferable refrigeration is reached.
Preferably, the distance of described adjacent secondary fin is identical.Folder between wherein first secondary fin 5 and main fin 4
Angle is 45 ° means secondary fin 5 perpendicular to the diagonal a line of main fin, simultaneously as secondary fin is parallel to each other so that second

0.23% Ti, 0.38% Si, remaining is Al.
The manufacture method of aluminium alloy is：Using vacuum metallurgy melting, argon for protecting pouring is uniform by 623 DEG C into round billet
Change is processed, at 412 DEG C, using bar is hot extruded into, then again by after 560 DEG C of solution hardening, artificial aging being carried out at 210 DEG C
Treatment.Thermal conductivity factor is more than 270W/ (m*k）.
Compared with previous studies, by increasing Cu and Ce contents, can greatly optimize the anticorrosive of aluminum alloy materials
Property, while also having high thermal conductivity factor.
Preferably, bent tube section is also adopted by being made with straight-tube portion identical material.
Preferably, for the distance between secondary fin it is changed according to certain rule, specific rule is from pros
The midpoint on the side of shape starts, to while two ends with it is foursquare described while vertical secondary fin the distance between increasingly
It is small.
For example as shown in figure 3, the adjacent two pair fin of the midpoint both sides positioned at cuboid side（Numbering is 1 ', 1 "）
Spacing is m, and other secondary spacings of fin are tapered into as the distance at the midpoint away from side becomes big.
