下一代微电子器件的高功率密度和紧凑性，以及燃料电池和微机电系统（MEMS）等新兴技术对高效热交换的日益增长的需求，需要创新的热管理解决方案。利用金属泡沫和纳米流体等新材料作为创新的热交换介质是满足这一迫在眉睫的需求的一个有吸引力的选择。维多利亚大学正在建立一个研究项目。所要求的设备为研究计划中的许多项目提供了测量扩散微尺度传热现象的核心能力，包括：a)金属泡沫中的传输现象B)燃料电池膜电极组件（MEA）的有效导热性C)纳米流体和热界面材料（TIM）的热特性。这些现象包括在真空和稀薄气体环境下的有效导热系数、热接触电阻（TCR）和地层系数，气体温度在50到300摄氏度之间，在一定范围的施加载荷下。所要求的设备能够进行实验，这对这项研究计划是绝对必要的。

The high-power density and compactness of next generation microelectronic devices as well as growing demands for efficient heat exchange in emerging technologies such as fuel cells and Micro Electro Mechanical Systems (MEMS) require innovative thermal management solutions. Utilizing new materials such as metalfoams and nanofluids as innovative heat exchange media is an attractive choice to satisfy this impending need. A research program is being established at the University of Victoria. The requested equipment provides the core capability for measuring diffusive microscale heat transfer phenomena in a number of projects in the research program, including: A) Transport phenomena in metalfoams B) Effective thermal conductivity in membrane electrode assembly (MEA) in fuel cells C) Thermal characteristics of nanofluids and thermal interface materials (TIM). These phenomena include effective thermal conductivity, thermal contact resistance (TCR) and the formation factor in vacuum and rarefied gaseous environment, with gas temperatures between 50 and 300 C, under a range of applied load. The equipment requested enables the experimentation which is absolutely essential to this research program.
