串联式网络矩形微通道对流换热实验分析-experimental analysis of convective heat transfer in series network rectangular microchannels

摘要随着电子元器件高密度组装技术的不断发展，由此产生的巨大发热量已经成为制约电子器件发展的瓶颈。微换热技术以其换热能力强、结构尺寸小，受到科研人员和技术人员的高度青睐。本文以实验的方法，研究了串联式网络矩形微通道对流换热特性。在对国内外电子元器件和微换热技术的研究应用情况进行深入了解的基础上，设计了矩形微通道对流换热实验系统；进行了串联式网络矩形微通道的流阻分析，编写了针对实验系统的流阻分析软件；对实验系统进行了数值仿真；对实验系统各分元件进行了设计、选取，进行了实验平台的搭建和数据的采集；对实验数据进行了分析，并分别与理论计算结果、数值仿真结果进行了对比；验证了微换热技术强大的换热能力；测得本实验系统矩形微通道对流换热系统的最佳流速为 0.9m/s；验证了速度滑移系数修正的串联式网络矩形微通道流阻理论的合理性；对微流体特性进行了分析，得出矩形微通道的努塞尔数低于宏观理论值。关键词：串联式网络矩形微通道流阻努塞尔数AbstractAs electronic components, high density assembly technology unceasing development, which has the great calorific value has become the bottleneck of the development of the check and supervision electronic devices. Micro heat exchange technology with its heat exchange ability, and the structure of small size, favored by the researchers and technicans. Based on the experimental method, studied the tandem network rectangular-micro-channel convection heat transfer characteristics. The rectangular- micro-channel convective heat transfer experimental system is designed and on the basis of in-depth understanding of the domestic and international electronic components and micro heat exchanger technology research and application; The tandem network rectangular- micro-channel fluid resistance analysis, write aiming at the system fluid resistance analysis software; The experimental system for the Numerical simulation; The experimental system each discrete element to carry on the design, selection, has carried on the experiment platform and data acquisition; Also analyses the experimental data, and respectively with the theoretical calculation result, the results of Numerical simulation were compared; Verify the micro heat exchange technology strong heat exchange ability; This experiment system measured rectangular- micro-channel convection heat exchange system optimal flow rate is 0.9 m/s; Verify the tandem network rectangular- micro-channel flow resistance theory modified by velocity slip coefficient; To the micro fluid properties is analysed and recta
