The experimental study was performed on five eccentric radial heat pipes with two outer-tube diameters.The test range can be given as follows,working fluid filling ratio Ω=44%～83%,heat flux q=10000W/m2～32000W/m2,and working temperature tv=50 ℃～120 ℃.The correlations between radial heat pipe heat transfer performance and filling ratio,heat flux,working temperature were studied in the experiment.Based on linear regression of experimental data,the relationship between heat pipe equivalent heat resistance R and working temperature tv,heat flux q and filling ratio Ω was obtained.
The experimental study was performed on five eccentric radial heat pipes with two outer-tube diameters. The test range can be given as follows, working fluid filling ratio Ω = 44% -83%, heat flux q = 10000W / m2 ~ 32000W / m2 , and working temperature tv = 50 ° C. to 120 ° C. The correlations between radial heat pipe heat transfer performance and filling ratio, heat flux, working temperature were studied in the experiment. Based on linear regression of experimental data, the relationship between heat pipe equivalent heat resistance R and working temperature tv, heat flux q and filling ratio Ω was obtained.
