摘要
通过解热传导方程得到了半导体激光器列阵的热沉温升分布的解析表达式,并利用该解析式得到了热沉的温升分布图.分析了对流换热传热系数对上下表面温升的影响,当对流换热传热系数增大到某个值后,上下表面的温差变化很小,而温升随该系数的增大而降低,所得的结果与用有限元法算得的并经过实验验证的结果基本上是一致的.
Abstract
The analytical expression of the temperature rise of the heat sink of a diode laser array has been obtained by solving the heat conduction equation. The influence of convection heat transfer coefficient on the temperature rise of the top and the bottom surfaces has been analyzed. The temperature difference between the top and the bottom changes little when the convection heat transfer coefficient reaches certain value. The temperature rise decreases as the convection heat transfer coefficient increases. All of the results obtained are in accordance with that by the finite element method and confirmed by the experiment.
