With the research and development of theminiaturized technologies, 249
mini and micro-channel cooling systems have been widely used in the electronic devices. However, the heat transfer performance and friction factor for the micro-channel are still to be validated. The heat transfer characteristics and pressure drop in the micro-channel heat sinks with various geometrical configurations are investigated experimentally. It is foundthat the shape andthe size of roughness irregularities of themicro- channel surface have significant effect on enhancement of heat transfer performance and the pressure drop variations.

Answer 1

随着微型化技术的研究和发展，249微型和微通道冷却系统已经在电子设备中得到了广泛的应用。不过，微通道的热传导效果和摩擦因子仍然有待考证。实验正在研究随着多种地域性的条件而变化的微通道热的热传导特性和压降。已经发现微通道粗糙不规则表面的形状和大小对促进热传导效果和压降变化有着显著的效果。
