| 摘 要： | 文章采用蒙特卡罗法模拟射线的传输过程,分别对两种热沉形式的热辐射当量吸收系数进行了数值计算,研究了表面形式、几何高度及入射光线方向等参数对表面热辐射当量吸收系数的影响.计算表明,正六边形凹腔形式的吸收效果远好于正四棱锥形式,但这种结构形式的吸收有明显的方向性,正四棱锥形式对光线的吸收呈现各向同性.

| Abstract: | Two kinds of heat sink are studied by Monte-Carlo method for the influence of some parameters, such as surface style, height, and light direction, upon the equivalent absorption coefficient of thermal radiation. The numerical calculation results show that the absorption of the heat sink with hexagonal hollow is better than that with quadrangular taper, but with more anisotropy. |
