The optimum inclination angle is between 15 ~ 20 , the length of thermosyphon will not change the phase - change heat transfer coefficient of the evaporation section and the condensation , which will enlarge heat transfer area of thermosyphon and increase the heat exchange capacity . the head - on speed of wind only stranger the heat transfer of the evaporation section and the condensation section . the experiment shows that the mathematic model closely fits to the thermosyphon , moreover , the one key to resolve the thermosyphon effect lies in decreasing the thermoresistance of evaporating section and condensation section . this study can provide directions and experience in the future research 傾斜角越大,熱虹吸管總熱阻越大,最佳傾角在15 20之間;充液率過多或過少都會對傳熱性能產(chǎn)生不利影響,對于本實驗采用的1 . 75m 、 2m 、 2 . 5m 、 3m熱虹吸管,最佳充液率在20 % 35 %之間;管長對傳熱也有影響,管長不改變熱虹吸管蒸發(fā)段和冷凝段的換熱系數(shù),只增加了熱虹吸管的換熱面積,增大換熱量;迎面風(fēng)速的大小,起到強化熱虹吸管蒸發(fā)段和冷凝段換熱的目的。
