不同结构下两弯头脉动热管的数值模拟
Numerical simulation of pulsating heat pipes with two-bends in different structures
摘要
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.关键词
