The length of the first secondary fin is along with shorter and shorter apart from the distance at main fin diagonal angle.
When the length on foursquare limit is certain, main fin and secondary fin longer, then heat transfer effect is better in theory, find in process of the test, when main fin and secondary fin reach certain length time, then heat transfer effect just increases very not obvious, main because along with main fin and the increase of secondary finned length, in the temperature of flight tip also more and more close to sink temperature, along with temperature is reduced to a certain degree, heat transfer effect then can be caused not obvious, also add the cost of material on the contrary, simultaneously, in heat transfer process, if the spacing between secondary fin is too little, also the deterioration of heat transfer effect is easily caused, because along with the increase of height, boundary layer is thickening, boundary layer between adjacent fins is caused to overlap mutually, worsen heat transfer, spacing between secondary fin causes too greatly heat exchange area to reduce, have impact on the transmission of heat, therefore in the distance of adjacent secondary fin, the foursquare length of side, an optimized size relationship is met between the length of main fin.
Therefore, the present invention is the dimensionally-optimised relation of the finned tube of the best summed up by thousands of test datas of the finned tube of multiple different size.

Compared with former research, by strengthening Cu and Ce content, the corrosion resistance of aluminum alloy materials can be optimized greatly, also there is high thermal conductivity factor simultaneously.
As preferably, bent tube section also adopts the material identical with straight-tube portion to make.
Preferably, be change according to certain rule for the distance between secondary fin, concrete rule is from the mid point on foursquare limit, to the two ends on limit the secondary fin vertical with foursquare described limit between distance more and more less.
Such as shown in Figure 3, adjacent two secondary fins (be numbered 1 ', the 1 ") spacing being positioned at the mid point both sides on cuboid limit is m, and other secondary spacings of fin diminish greatly and gradually along with the distance of the mid point apart from limit becomes.
Preferably, the amplitude of adjacent pair spacing of fin reduction is identical.Such as fin 1 ', 1 " distance be m, 1 ", 2 " between distance m-n, 2 ", 3 " between distance m-2n, 3 ", 4 " between distance m-3n, the like.
The unit of n, m is above mm.
Under the condition meeting optimization formula above, n preferably distance is 1mm.
It is little that spacing of fin presents two broad in the middle, increases again the heat exchange area of fin while that its main purpose being the flow field optimizing this panel region fin as far as possible.Namely under the prerequisite reducing the coefficient of heat transfer not too much, heat exchange area is increased as far as possible to reduce junction temperature as far as possible.
As shown in Figure 5, straight-tube portion is closely close together, and is also connected to each other between the fin of its corresponding straight-tube portion, thus forms the passage of low-temperature receiver.Because multiple finned tube is close together, thus make to define square space between adjacent four finned tubes, this square space can make low-temperature receiver flow through from centre, thus between the fin being distributed to adjacent finned tube in flow process, ensure that enough low-temperature receivers, to avoid cooling not enough.
As preferably, low-temperature receiver is ethylene glycol.Prove by experiment, under above-mentioned size relationship, ethylene glycol can obtain best cooling effect.
As preferably, described cooler also comprises control system, and described control system controls according to the output temperature of beer the flow velocity entering low-temperature receiver in cooler;
Described control system comprises: temperature sensor, flow controller and central controller, and flow controller controls the flow velocity entering the low-temperature receiver of cooler, described temperature sensor is for measuring the output temperature of beer, when output temperature reaches the first temperature, central controller controls flow controller reaches the first flow velocity, when output temperature reaches the second temperature lower than the first temperature, central controller controls flow controller reaches the second flow velocity lower than the first flow velocity, when output temperature reaches the 3rd temperature lower than the second temperature, central controller controls flow controller reaches the 3rd flow velocity lower than the second flow velocity, when output temperature reaches the 4th temperature lower than the 3rd temperature, central controller controls flow controller reaches the 4th flow velocity lower than the 3rd flow velocity, when output temperature reaches the 5th temperature lower than the 4th temperature, flow controller cuts out by central controller, stops low-temperature receiver to enter cooler.
Above-mentioned temperature sensor is arranged on the position of beer outlet, and flow controller is arranged on the position of the entrance of low-temperature receiver.
Described control system can be a single-chip microcomputer, can arrange control panel, and control panel is arranged on top or the bottom of radiator, also can be arranged on and enter on the pipeline of radiator.
As preferably, the inwall of coiled pipe 5 is provided with projection, for augmentation of heat transfer, the distribution of described projection is according to certain rule.Preferably, along the flow direction of beer, protruding distribution is more and more closeer, like this, be the direction along with beer flowing, the temperature of beer declines gradually, its refrigeration is reduced gradually, by increasing the density of the projection of inner fins, the refrigeration on beer flow direction can be strengthened, thus the cold effect of political affairs is consistent on the whole along beer flow direction.The direction that to be protruding height flow along with beer increases another mode preferred gradually, and wherein the highest is minimum 1.03-1.10 times.Identical with heat exchange principle above, main cause is the direction along with beer flowing, the temperature of beer declines gradually, its refrigeration is reduced gradually, by the height increasing internal protrusion, difference is set, the heat exchange on beer flow direction can be strengthened, thus refrigeration is consistent on the whole along fluid flow direction.
Although the present invention discloses as above with preferred embodiment, the present invention is not defined in this.Any those skilled in the art, without departing from the spirit and scope of the present invention, all can make various changes or modifications, and therefore protection scope of the present invention should be as the criterion with claim limited range.
