1歧管微通道热沉研究进展与展望显示文摘随着电子设备的快速发展,其功率及热流密度急剧增加,对热管理的要求也越来越高。近年来出现了很多新兴的电子设备热管理技术,其中歧管微通道热沉由于其高散热能力、低压降损失以及高可靠性等优势被认为是最具前景的电子设备冷却技术之一。基于此,本文介绍了歧管微通道热沉的散热原理及优势,对几何参数、结构优化等方面的相关研究进行了回顾,并对其未来发展进行了展望。朱迅仪 陈超伟 张井志 辛公明 2023制冷学报2023,44,4:0
2Constructal design of printed circuit recuperator for S-CO_(2)cycle via multi-objective optimization algorithm显示文摘Based on a constructal theory,the structure design of a printed circuit recuperator with a semicircular heat transfer channel for supercritical CO_(2)cycle is carried out.First,a complex function composed of weighted sum of the reciprocal of total heat transfer rate and total pumping power consumption is regarded as an optimization objective,and total volumes of the recuperator and heat transfer channel are regarded as constraints.The optimal heat transfer channel radius and minimum complex function of the recuperator are obtained.It turns out that heat transfer rate,pumping power consumption,and complex function under the optimal construct of recuperator are reduced by 15.10%,82.44%,and 32.33%,respectively.There exists the optimal single plate channel number which results in the double minimum complex function.Second,for the purpose of minimizing the reciprocal of heat transfer rate and pumping power consumption,NSGA-II algorithm is used to achieve multi-objective optimization,and the minimum deviation index derived by the decision-making methods is 0.076,which can be taken as multi-objective optimal design scheme for printed circuit recuperator with semicircular heat transfer channels.The findings presented here can serve as theoretical recommendations for the structure design of printed circuit recuperator.DAN ZhiSong FENG HuiJun CHEN LinGen LIAO NaiBing GE YanLin 2024Science China(Technological Sciences)2024,67,1:0
