RT Journal Article ID 2cfe8e7a0d13aec3 A1 Qu, Wei A1 Ai, Bangcheng A1 Yu, Jijun T1 PRECISE DIFFERENTIAL MECHANISM, SODIUM CHARGING EQUIPMENT AND HEAT PIPE PERFORMANCE JF Heat Pipe Science and Technology, An International Journal JO HPST YR 2014 FD 0000-00-00 VO 5 IS 1-4 SP 253 OP 259 K1 single and double differential mechanisms K1 precise charging K1 non-distillation equipment of sodium K1 high temperature heat pipe K1 good performance. AB The single and double differential mechanisms of heat pipe precise charging are invented and introduced, the precisions of them are calculated quantitatively. The double gear wheels coupling with the two-piston tank can realize double differential precision and has much more precise than that of single wheel. The non-distillation equipment of sodium charging is illustrated, and the vacuum demand boundary of charging a heat pipe is determined by the heat pipe performance failure. The fabricated high temperature heat pipe has good performance. PB Begell House LK https://www.dl.begellhouse.com/journals/4b0844fc3a2ef17f,18c058f17ecbe0d2,2cfe8e7a0d13aec3.html
