Preferably, from 103 lower part of VERTICAL TUBE to 103 top of VERTICAL TUBE, constantly subtract the distance between adjacent communicating pipe 107 It is small.This purpose is in order to which more communicating pipes are arranged, because of flowing up with fluid, fluid is constantly heated, with stream Body is constantly heated, heated more and more uneven in different thermal-collecting tubes, therefore by above-mentioned setting, can ensure in fluid stream Reach pressure equilibrium during dynamic as soon as possible.
Preferably, from 103 lower part of VERTICAL TUBE to 103 top of VERTICAL TUBE, constantly reduce the distance between adjacent communicating pipe Amplitude it is increasing.It is found through experiments that, above-mentioned setting, can ensure more excellent in process fluid flow to reach pressure faster Power is balanced.This is also the best mode of communicating got by largely studying pressure changes in distribution rule.
Preferably, from 103 lower part of VERTICAL TUBE to 103 top of VERTICAL TUBE, the diameter of communicating pipe 107 is continuously increased.This mesh Be in order to be arranged ensure bigger connection area, because of flowing up with fluid, fluid is constantly heated, with fluid It is continuous heated, it is heated more and more uneven in different thermal-collecting tubes, therefore by above-mentioned setting, can ensure to flow in fluid Reach pressure equilibrium as soon as possible in the process.
Preferably, from 103 lower part of VERTICAL TUBE to 103 top of VERTICAL TUBE, the ever-increasing amplitude of diameter of communicating pipe 107 It is increasing.It is found through experiments that, above-mentioned setting, can ensure that more excellent in process fluid flow to reach pressure equal faster Weighing apparatus.This is also the best mode of communicating got by largely studying pressure changes in distribution rule.
Found by numerical simulation and experiment, the distance between VERTICAL TUBE 103, including the distance of same row and adjacent row it Between distance cannot be too small, it is too small that heat pipe distribution can be caused excessive, cause the caloric receptivity of every heat pipe insufficient, crossing conference leads to heat Pipe distribution is very little, causes heat pipe to overheat, therefore the application sums up by a large amount of numerical simulation and experiment and carrys out heat pipe VERTICAL TUBE The distribution of the optimizations of 103 distributions so that heat pipe can neither recept the caloric deficiency, and it is excessive to recept the caloric.
As shown in fig. 7, the outer diameter of VERTICAL TUBE 103 is d, the distance between adjacent 103 center of circle of VERTICAL TUBE of same row is The apex angle that L, the center of circle of VERTICAL TUBE 103 and two closed on VERTICAL TUBE, 103 center of circle of adjacent row constitute isosceles triangle is A, then Meet claimed below：
Sin（A）=a*( d/L)2- b* (d/L)+c, wherein a, b, c is parameter, meets following require：
1.03<a<1.09,1.73<b<1.74；0.895<c<0.906,0.1< d/L<0.7.
Preferably, a=1.07, b=1.735, c=0.901.
Preferably, tapering into d/L, a is increasing, and b is smaller and smaller, and c is increasing.
Preferably, 15 °<A<80°.
Further preferably, 20 °<A<40°.
Further preferably, 0.3< d/L<0.5.
Above-mentioned empirical equation is obtained by a large amount of numerical simulations and experiment, the structure obtained by above-mentioned relation formula, energy It is enough to realize the heat pipe structure optimized, and pass through verification experimental verification, error is substantially within 3%.
The heat absorption capacity 900-1100W of heat pipe, further preferably 1000W；
