铝基Al2O3纳米多孔表面大容积池沸腾实验
Experimental study on pool boiling of aluminum base Al2O3 nano-porous surface
摘要
Abstract
The problem of heat dissipation is the bottleneck for the further development of micro-devices because the high density,microminiaturization and functional systemic. In this paper, Nano-porous surfaces’ excellent phase change heat transfer characteristics were analyzed to solve this problem. An experimental study on the pool boiling heat transfer performance of the aluminum base Al2O3 nano-porous film was conducted with water under normal pressure. Experimental results showed that Al2O3 nano-porous surface improved the heat transfer coefficient of the aluminum heat transfer surfaces 2—5 times compared with the smooth-surfaced devices,and could maintain high heat transfer coefficient in a long time,because the intensive vaporized core could produce large amount of small bubbles. The surface temperature of microelectronic could be effectively decreased by 3—5℃,even by more than 30℃ in nucleate boiling stage with nano-porous surface as heat transfer surface.关键词
