复合沟槽平板热管的理论建模与实验研究
|
摘要
通过对复合沟槽平板热管的结构分析和影响传热极限因素的分析,建立了复合沟槽平板热管的毛细极限、携带极限、沸腾极限等各传热极限的理论模型,计算了热管各传热极限的理论值。通过热管传热性能实验发现最大传热量与理论计算值相当,从而证明了所建立的热管传热极限理论模型的正确性。
Based on the analysis of the structure of the plate heat pipe with a composite-grooved wick structure and the influence of the heat transfer limit factors,the theoretical models of the capillary limit,entrainment limit and boiling limit of the composite-grooved plate heat pipe were established,and the theoretical values of heat transfer limit of flat heat pipe were calculated.The heat transfer performance experiment was also carried out,and the experimental results show that the maximum heat transfer is equivalent to the theoretical calculation,which demonstrates that the theoretical model on heat transfer capacity is correct.
