The simulated results showed that the heat dissipation efficiency could be enhanced with the increasing of the fin spacing distance, hole density, hole diameter, and with the decreasing of the fin thickness %K 多孔翅片 %K 散热器 %K 铲削加工 %K 耦合仿真 %K 强化散热< %K br> %K perforated fin %K radiator %K planning process %K coupling simulation %K intensified heat dissipation %U http://journals.nwpu.edu.cn/jxkxyjs/CN/abstract/abstract7197.shtml
