水平矩形散热片通道内气流速度场测量实验研究

Study on the Measurement of Air Velocity Field of Horizontal Rectangular Fins in Channels

用恒温热线风速仪在风洞中测量了强制对流条件下，基面竖直放置、侧壁与流动平行时，散热片通道内空气的速度分布。以散热片间距作为特征尺寸，实验雷诺数范围Ｒｅ＝５１００～３１６００。通过对实验结果分析，探讨了散热片的高度、间距和长度对流动的影响。

A constant temperature hot wire anemometer is used to measure the air velocity field in channels of verticalbased horizontal rectangular fins inside a wind tunnel under the condition of forced convection.The Reynolds number ranges from 5100～31600 with the fin spacing as feature size.The affect of fin height,fin spacing and fin length to air flow has also been discussed by analyzing the experimental results.
