| 摘 要： | 利用CFD软件FLUENT对流体在热管换热器中纵向冲刷方式进行数值模拟,对流场中压降、温度等参数进行了分析。结果表明,在相同情况下纵向冲刷时的流体压降小于横向冲刷,但纵向冲刷时传热效果较差;纵向冲刷时流体压降受管间距与热管长度等因素的影响,并且与热管长度成正比。在热管上加装纵向翅片可有效地改善流体纵向冲刷的换热效果,并且使流场内温度分布更为均匀。

| Abstract: | The numerical simulation was used to study the vertical scour way of fluid in the heat pipe exchanger by using CFD software FLUENT,and the flow field parameters such as pressure drop,temperature were analyzed.The results show that fluid pressure drop in the vertical scour way was less than fluid pressure drop in the lateral scour way under the same situation.But the heat transfer effect was poorer.The fluid pressure drop was affected by tube spacing and length in the vertical scour way,and fluid pressure drop was proportional to the tube length.The vertical scour fluid heat transfer effect could be improved effectively when the longitudinal fins were added to the heat pipe,which made the temperature distribution in the flow field be more uniform. |
