By further analyzing, preliminary reason may be as the capillary force close to condensation end is increasing, so that condensation
The liquid at end can be quickly drawn onto capillary wick, and liquid is constantly flowed to evaporation ends.In flow process, liquid is not
Disconnected heat absorption, then because temperature caused by absorbing heat increases, density becomes smaller, therefore because of variable density reason, the hair for needing it
Thin power obviously becomes smaller, therefore is also easy for up inhaling in the case where capillary force is small.Above-mentioned reason is that the present inventor passes through
What a large amount of experiment and research obtained, the common knowledge of non-this field.
Further preferably, along height descent direction, the amplitude that the capillary force of the capillary wick gradually increases is increasing.

Preferably, air outlet passage 4 is arranged between the vertical fin 12 of adjacent two and erects with adjacent two
Straight fins 12 contact.Pass through such setting, it is possible to reduce the mechanism of the independent support air outlet passage 4 of setting, so that structure
Compact, the cold air of exit passageway can be exchanged heat by pipeline and fin, kept the cold degree of fin, enhanced heat transfer effect.
Preferably, evaporation ends flow direction condensation end pipeline 9 be arranged between the vertical fin of adjacent two and with it is adjacent
Two vertical fin contacts.Pass through such setting, it is possible to reduce the mechanism of the independent support air outlet passage 4 of setting makes
Must be compact-sized, the steam in pipeline can reduce system overall thermal resistance, avoid on ground by pipeline to the of short duration a small amount of heat transfer of fin
Steam superheating is generated in the case of the antigravity of face in evaporator, to slow down the temperature oscillation phenomenon in heat pipe start-up course.
Further preferably, the pipeline 9 than air outlet passage 4 closer to the outer wall of evaporation ends pipeline so that above-mentioned
Two diabatic processes can be achieved at the same time, and play respective action.
Further preferably, the diameter of the pipeline 9 is less than air outlet passage 4.
Preferably, along the condensation end pipeline 9 that multiple evaporation ends flow directions can be set, as shown in Fig. 7,9.Pass through setting
Multiple pipelines 9 can make evaporation ends inhale thermogenetic steam and enter condensation end by multiple pipelines 9, further augmentation of heat transfer,
And the evaporation because the fluid in heat pipe absorbs heat, cause volume to increase, by the way that multiple pipelines 9 are arranged, can further alleviate pressure
Power improves heat transfer effect.
Further preferably, the vertical fin extends through the center of circle of the inlet tube of condensation chamber, the evaporation ends ascent stage
The inlet tube of the pipeline and condensation chamber center of circle having the same.
Preferably, the pipeline 9 be it is multiple, between the center of circle and evaporation ends ascent stage pipeline of the multiple pipeline 9
Apart from identical.
Further preferably, per one pipeline 9 of setting between adjacent two vertical fins 12.The pipeline 9 is in parallel

Pass through above-mentioned setting, it is ensured that pipeline 9 and air outlet passage 4 carry out the uniform of cooling to inlet air, keep away
Exempt from local income inequality, leads to effect variation of fetching water.
It, can not in numerical simulation and it was found that, the caliber of air outlet passage 4 and pipeline 9 difference cannot be too big
Too small, the distance for causing very much air outlet passage 4 and pipeline 9 to be distributed greatly is too far, leads to the sky between channel 4 and pipeline 9
Gas heat exchange is bad, causes overall heat exchange uneven, and the distance for causing air outlet passage 4 and pipeline 9 to be distributed if too small is too close,
The air heat-exchange of the air and/or the outer wall close to evaporation ends 6 that lead to the outer wall close to air inlet passageway 5 is bad, causes whole
Air heat-exchange in body air inlet passageway 5 is uneven；Same reason, the angle between adjacent fins 12 cannot be too big, too
It will lead to that distribution fin is few, and heat transfer effect is excessively bad if big, also result in air outlet passage 4 and quantity that pipeline 9 is distributed
Very little, cause heat exchange unevenly and heat transfer effect is bad, similarly, the angle between adjacent fins 12 cannot be too small, too small
Words cause fin distribution too close, and flow resistance increases, and the caliber of air outlet passage 4 and pipeline 9 is not much different, but he
Differ greatly with the exchange capability of heat of homalographic, therefore heat exchange is uneven in such cases, causes heat transfer effect bad.Therefore it needs
Optimal size relationship is determined by a large amount of numerical simulation and its experiment.
The radius of air outlet passage 4 is R, and the radius of pipeline 9 is r, and the angle between adjacent fins is A, is met following
