摘要: 为了探索在电子设备冷却中应用固液相变冷却的可能性,本文用数值方法求解了一侧垂直壁上有三个分散热源、其余三个面均绝热时矩形区域内的二维熔化传热问题,对固液界面形状以及加热壁面温度沿高度方向的变化规律进行了讨论。

Abstract: In order to simulate the cooling of electronic devices by solid-liquid phase change materials (PCM) the problem on two-dimensional melting heat transfer in a rectangular enclosure with discrete heat sources on one of its vertical walls has been solved numerically.Effect of Stefan number on the solid-liquid interfacial shape and wall temperature varition along the height of the wall are also discussed.

Key words: discrete heat sources, rectangular enclosure, melting heat transfer, numerical solution
