Construction Technology of Cooling Channel Based on Adaptive Growth Method

应用自然界生物分枝网形态成长机理的自适应成长法对体-点问题进行求解,以每一单元的材料热导率作为设计变量,以设计区域的最高温度最低为设计目标,根据设计领域的温度梯度,逐步将高导热材料填充到设计区域,实现自适应成长。以若干典型体-点问题为算例,通过与现有设计方法的结果进行比较,说明提出的自适应成长技术可有效地应用于散热通道的构建。

The adaptive growth method based on the growth mechanism of branch systems mor- phologies in nature was applied to solve volume--point problem. The thermal conductivity of each ele ment was selected to be as design variable and minimization of the maximum temperature in the de- sign area was the objective. The material with high thermal conductivity was distributed gradually to the design area and the adaptive growth of cooling channel was realized. Several typical volume--point problems were analyzed and compared with the results of current methods. It is found that the adap- tive growth method can be used to construct cooling channel effectively.
