摘要

脉动热管以其独特的换热优势，在电子器件的散热领域取得了卓越的成效。因此提出一种带有锯齿波纹段的两弯头新型脉动热管，并采用数值方法研究了波纹段的布置位置对脉动热管运行性能的影响。结果表明新结构脉动热管的传热性能和启动特性都优于传统结构的脉动热管。此外，当锯齿段布置在热管两端时，具有较短的启动时间，尤其位于冷凝段时锯齿型脉动热管具有更低的温差和最大的换热量。因此可以认为当波纹段位于冷凝段时，新结构脉动热管具有最优的运行特性。

Abstract

The pulsating heat pipe (PHP) has achieved remarkable results in heat dissipation field of electronic devices for its unique advantages in heat transfer. Therefore

this paper proposed a novel saw-tooth corrugated structure PHP with two-bends. Besides

the impact of arrangement position of saw-tooth corrugated section on the operation performance of PHP was investigated by numerical simulation. The results indicate that the heat transfer performance and start-up characters of saw-tooth corrugated PHP are much better than that with traditional structure of PHP. Additionally

the PHP has the lowest start-up timing with the serrated corrugated section in both ends of the heat pipe. Especially

the novel structure PHP with serrated corrugated part in condensation section has lower thermal resistance and higher heat exchange. Thus

it could conclude that the novel saw-tooth corrugated PHP has the best operation performance as new structure is arranged in condensation section.
