对导热平板上复合传热的实验研究,可以确定出平板的方向以及受迫气流与气流浮升力间夹角对平板壁面温度的影响程度。这些实验是在气流速度范围为1.75—5.0m/s,热通量为1350w/m~2和2700w/m~2的条件下进行的,同时,实验中四种典型的平板方向也是微电子技术应用中常见的。结果表明,在整个试验速度范围内,平板的表面方向对其壁面温度有显著的影响。
The experimental study on the composite heat transfer on the heat conduction plate can determine the direction of the plate and the degree of influence of the included angle between the forced air flow and the airflow buoyancy on the plate wall temperature. These experiments were performed at airflow velocities ranging from 1.75 to 5.0 m / s with heat flux of 1350 w / m 2 and 2700 w / m 2, and the four typical plate orientations in the experiment were also microelectronics Commonly used in the application. The results show that the surface direction of the slab has a significant influence on the wall temperature over the entire test speed range.
