The heat transfer characteristics of latent functionally thermal fluid in micro tube
摘要
Abstract
Due to its excellent heat transfer properties,the latent functionally thermal fluid shows a promise of application in high efficiency heat transfer area such as modern electronic devices cooling. To study the performance of the fluid,the heat transfer characteristics of 5%,10% and 15% mass concentration latent functionally thermal fluid as well as the deionized water was experimentally investigated in the present work. The results showed thatthe averageNu number increased withRe number,and by cooling with latent functionally thermal fluid,the temperature of the wall could be reduced by 26.8% compared with the deionized water forRe number ranging from 300—1000. To clearly demonstrate the relationship between theNu number,Re number,mass concentration andPr number,an experimental formula was further fitted based on the experimental data,the maximum relative error of 7.5%,acceptable for experiments. According to these results,a conclusion can be made that the heat enhancement ratio of the latent functionally thermal fluid on the length direction of the pipe is related to the mass concentration andRe number,moreover,there exists an optimum length, in which the heat transfer is most enhanced.关键词
