电子设备的性能受到从这些设备移除热量的能力的限制。热管是一种促进热传输的设备，已经看到越来越多的使用来解决这一挑战。热管是一种能够以最小的温度梯度传输热量的两相传热装置。热管的一个重要组成部分是毛细结构，它将冷凝物从冷凝器输送到蒸发器。对高热传输能力和对外部加速度的高弹性的要求导致芯几何形状的设计折衷的必要性。这使得芯性能成为热管设计中的关键参数。本研究探讨了测试毛细结构的毛细性能的实验方法，范围从微米到纳米尺度。这些技术将有助于开发用于高性能热管的纳米工程吸液芯结构。Copyright © 2008 by ASME
The performance of electronic devices is limited by the capability to remove heat from these devices. A heat pipe is a device to facilitate heat transport that has seen increased usage to address this challenge. A heat pipe is a two-phase heat transfer device capable of transporting heat with minimal temperature gradient. An important component of a heat pipe is the wick structure, which transports the condensate from the condenser to the evaporator. The requirements for high heat transport capability and high resilience to external accelerations leads to the necessity of a design trade off in the wick geometry. This makes the wick performance a critical parameter in the design of heat pipes. The present study investigates experimental methods of testing capillary performance of wick structures ranging from micro- to nano-scales. These techniques will facilitate a pathway to the development of nano-engineered wick structures for high performance heat pipes.Copyright © 2008 by ASME
