Certainly, the present invention also provides a kind of radiator, and this kind of radiator can be used as an independent radiator product and protect.
Described hot user's radiator is finned tubular radiator, comprise upper header 14, lower collector pipe 17 and be connected upper header 14 and the finned tube 16 of lower collector pipe 17, described finned tube 16 comprises circular base tube 18 and the first fin 19, the second fin 22, the extended line that the first fin 19 and the second fin 22 are arranged on outside and the first fin 19 and second fin 22 of base tube 18 intersects at the central axis of the base tube at the place, the center of circle of base tube 18, and the first fin 19 and the second fin 22 are along by the first plane B mirror image symmetry of base tube central axis; Described finned tube comprises the 3rd fin 24 and the 4th fin 23, described the 3rd fin 24, the 4th fin 23 along the second plane C respectively with the first fin 19 and the second fin 22 mirror image symmetries, described the second plane C is vertical with the first plane B and through the central axis of base tube 18; Between described the first fin 19 and the second fin 22, the first brace 21 is set, it is circular arc type metallic plate that the second brace 25, the first braces 21 and the second brace 25 are set between described the 3rd fin 24 and the 4th fin 27; The central axes of the central axis of described circular arc-shaped metal plate and base tube 18; Described base tube is straight tube, and the central axis of described adjacent base tube is parallel to each other.
Preferably, the first fin of adjacent base tube is parallel to each other, represents that the second fin of adjacent base tube is also parallel to each other, and in like manner, the 3rd fin, the 4th fin are also parallel to each other.This feature shows that finned tube arranges according to equidirectional.
It should be explained that, as shown in Figure 3, the central axis of base tube is exactly the line that the set of the centre point on the cross section of base tube 18 forms, and the central axis of circular arc-shaped metal plate is exactly the line that the set of the centre point of circular arc-shaped metal plate on cross section forms.The central axes of the central axis of described circular arc-shaped metal plate and base tube 18 just refers to that, on cross section, circular arc-shaped metal plate and base tube are concentric circles.
Preferably, the size of all finned tubes is all identical.
By above-mentioned setting, make to form a gap 20 between fin and brace, in heat convection, gap 20 has just formed a kind of chimney effect, can strengthen heat exchange.
The 3rd fin of the first fin, the second fin and adjacent fins pipe and the 4th fin form space, and this space forms certain space, can form chimney effect, adds strong convection, augmentation of heat transfer.
Angle between described the first fin and the second fin is A, and the length of the first fin and the second fin is L, and the outer radius of base tube is R, and certainly, because mirror image symmetry, the length of the 3rd fin and the 4th fin is also L naturally.But find in practice, if in heat transfer process. fin angle is too small, can hinder heat exchange, because the words that fin angle is too small, cause the first fin, the distance of the second fin is too near, temperature boundary layer starts in the direction along with base tube height to overlap in closed area, gas temperature approaches tube wall temperature and moves closer to hot saturated, flow resistance increases, finally worsen on the contrary heat exchange, the advantage of outer fin is brought into play not out, same reason, along with the constantly increase of angle, make brace originally nearer apart from the distance of base tube, make equally temperature boundary layer in closed area, in the direction along with base tube height, start to overlap, gas temperature approaches tube wall temperature and moves closer to hot saturated, flow resistance increases, finally worsen on the contrary heat exchange, therefore angle has an optimum value.
For finned length, if oversize, even because the heat of base tube could arrive in time the end of fin or be effective also not obvious, if too short, expand heat exchange area too little, cannot reach a good heat transfer effect, therefore the height of fin also has an optimum value.
For the distance between two finned tubes, if first distance is too near or completely close, between the brace of two finned tubes, the space of distance (referring to Fig. 2) is too little, air cannot enter the space forming between finned tube by the gap between fin, heat exchange now can only rely on from radiator bottom and enter air, cannot reach good heat convection effect, same reason, if the distance is too far, the the one the second the 3 4th fins of finned tube cannot form the space of effective chimney effect, thereby cause heat transfer effect variation, therefore also need a suitable numerical value for the distance between two finned tubes.
As shown in Figure 3, the base tube of height H on axial along to(for) fin, also need to have a suitable numerical value, if fin height is too high, on the top of fin, because boundary layer starts in the direction along with base tube height to overlap in closed area, cause the deterioration of heat exchange, in like manner, highly too low, heat exchange is not given full play to, thereby affects heat transfer effect.
Therefore, the present invention is the size relationship of the finned tube of the best radiator that sums up of the test data of the radiator by multiple different sizes.Because finned tube also has included angle A, these three variablees of finned length L, fin height H, therefore, introduce two characteristic sin (A/2), L/R, H/R, R is the radius of base tube here, heat dissipation capacity maximum from heat transfer effect, has calculated nearly 200 kinds of forms.Described size relationship is as follows:
Angle between described the first fin and the second fin is A, and the length of the first fin and the second fin is L, and the outer radius of base tube is R, the fin height H along base tube on axially, and above-mentioned four relation meets following formula:
Sin(A/2)=a×(L/R)
2+b×(L/R)+c
H/ (R × 10)=e × Sin (A/2)
2wherein, A unit is angle to-f × Sin (A/2)+h, 60 ° of <A<110 °,
L is of a size of mm, 12mm<L<80mm,
The unit of R is mm, 10mm<R<80mm,
The unit of H is mm, 800mm<R<1200mm,
A, b, c, e, f, h are coefficient, and the scope of a is 0.04-0.042, and the scope of b is 0.266-0.28, and the scope of c is 0.36-0.37, and the scope of e is 21-23, and the scope of f is 44-45, and h is 23-25.
By testing after result of calculation, by the numerical value of computation bound and median, the result of gained matches with formula substantially again, and error is substantially in 4%, and maximum relative error is no more than 6%, and mean error is 2%.；
The optimum of coefficient optimization is: a is that 0.0412, b is that 0.02715, c is that 0.03628, e is that 22, f is that 44.37, h is 23.86.
Preferably, the distance between adjacent base tube central axis is S=d × (L+R) × sin (A/2), and wherein d is 1.1-1.2.
As shown in Figure 3, the distance between adjacent base tube central axis is exactly the distance between two base tube centers of circle on cross section.
The optimum results of d is 1.118.
As one preferably, described heat exchanger 7 is heat-exchangers of the plate type.
As one preferably, as shown in Figure 5,6, the first fin of described radiator and the fin height of the second fin diminish to top gradually from the bottom of user's radiator.By such setting, can make in the flow process of air in the space of fin, gap 20 areas are more and more less, thereby make its flow velocity more and more faster, and chimney effect is more and more obvious, thereby strengthens heat exchange.
As one preferably, the amplitude that the first fin of described radiator and the fin height of the second fin diminish to top gradually from the bottom of user's radiator is more and more lower.Experiment showed, in radiator, by such setting, it is constant or become gradually large situation that heat transfer effect will obviously be better than the amplitude that changes.
As one preferably, the first fin of described radiator and the fin height of the second fin are parabolic structure to top from the bottom of user's radiator.This set is that fairshaped effect has been played in the variation of fin, reaches best heat transfer effect, because bottom extension goes out a part, makes more air enter gap simultaneously.
For two kinds of situations of Fig. 5 and Fig. 6, it is A that the fin of radiator still can adopt the angle between described the first fin and the second fin, the length of the first fin and the second fin is L, the outer radius of base tube is R, the satisfied formula of fin height H on axial along base tube, but consideration ease of processing, can finned tube be divided into several parts in short transverse, every part is taked average fin height H, but length L remains unchanged, adopt the mode of total length, determine included angle A by average fin height.
Can certainly, directly by adopting average fin height, calculate an angle, remain unchanged along the height angle of fin.
Certainly, in particular cases, because the difficulty of manufacturing, fin also not necessarily leaves no choice but meet the optimization formula of above-mentioned several parameters, also can be set to be convenient to the mode of manufacture, for example as shown in Figure 6, fin is the mode of straight line, remain unchanged, but circular arc closure plate is apart from the distance in the center of circle of finned tube base tube, constantly reduces along the height of base tube highly always.
As preferably, circular arc closure plate is apart from the distance in the center of circle of finned tube base tube, along the streamlined variation that is parabolic in short transverse, because bottom extension goes out a part, makes more air enter gap simultaneously
Certainly, the embodiment of Fig. 6, also can meet the formula of above-mentioned optimization, but manufactures cumbersome.
Preferably aluminium alloy of the material of base tube and fin, the mass percent of the component of described aluminium alloy is as follows: 1.4% Cu, 2.8% Mg, 3.2% Ag, 1.2% Mn, 0.42% Zr, 0.15% Fe, 1.18% Ti, 18.38% Si, 0.4% Cr, 1.1% Ni, all the other are Al.
The manufacture method of aluminium alloy is: adopt vacuum metallurgy melting, argon for protecting pouring becomes circle base, through 600 DEG C of homogenising processing, at 400 DEG C, adopts and is hot extruded into bar, and then after 580 DEG C of solution hardening, carry out artificial aging processing at 200 DEG C.Thermal conductivity factor for being greater than 250W/ (m*k) under 50-70 degree celsius temperature.
