通过自然对流传热对电子元件进行被动冷却是最便宜、最安静、最可靠的散热方法。然而，一些固有的现象，如热源之间的非线性相互作用的特点，难以其实际应用。本文研究了基于遗传算法的自然对流换热优化问题。研究了四个案例：一个热源、两个散热速率相同的热源、以及两个散热速率不同的热源。结果表明，与文献吻合良好，并证实了该方法的计算是可行的热源在垂直壁的最佳位置。
Passive cooling of electronic components by natural convection heat transfer is the least expensive, quietest and most reliable method of heat rejection. However, some characteristics intrinsic to the phenomenon, such as a non-linear interaction between heat sources difficult its practical application. The objective of this work is to study the natural convection heat transfer optimization through genetic algorithms. Four cases were studied: one heat source, two heat sources with same dissipation rate, and two heat sources with different dissipation rates on a vertical wall. The results showed good agreement with literature and confirmed the methodology as computationally feasible for the optimal location of heat sources in a vertical wall.
