摘要:
实验测量了由振荡热管冷凝段构成的平板表面中管束壁面上横向和纵向温度,对升负荷和降负荷过程中壁面温 度分布特性进行了分析.实验表明平板表面外侧管壁面温度波动幅度较大,中间点温度比较均匀;受管束内汽液流动及剧烈 振荡的影响,在热管蒸发段壁面温度达到90℃时,平板表面温度均匀程度最好;当蒸发段壁面温度为120℃时,横向各点温 度相差比较大.管束壁面纵向温度分布实验表明:蒸发段壁面温度为40℃时,热管未启动;而在120℃时热管完全启动,各测 点温度相差不大;在60℃～80℃时,纵向温度相差较大,温度分布不均匀,靠近蒸发段的测点温度升高较快;蒸发段壁面温度 在80℃以上时,平板表面纵向温度趋于均匀.
Abstract:
A plate surface was form ed w ith the condensing sec tion tubes o f the O sc illating H eat Pipe, the tube w a ll tem perature is expe rim entally m easured a long the crossw ise and vertica l d irection o f the Osc illa ting H ea t Pipe, and som e analyses arem ade about the tem pe rature d istributive character istics during the rising heating load and the decl-i n ing heating load. The experim ent show s that the temperature on the outside tube is fluctuated apparently but is even in the center, and that when the evapo ra ting section tem pera ture r ises up to 90℃ , the p la te surface tem perature is a t the best even, but that when the evaporating section tem pera ture r ises up to 120℃ , the crossw ise temperatu re is no t the sam e, and tha tw hen the evaporating section tem pera ture rises up to 40℃ , the oscillating heat pipe is not started, but that when the temperature r ises up to 120℃ , the heat pipe is fully started and the ve rtica lw all temperature is the sam e; and thatw hen the evapo ra ting section temperature is betw een 60~ 80℃ , the verticalw a ll tem pera ture is different and the temperature near the ev aporating section r ises quickly, and tha tw hen the evapo ra ting section tem pe ra ture r ises up to 80℃ , the ve rtica l tem pe rature on the plate sur face is even.
