摘要:
为确定强迫风冷散热器风道的风阻大小,以便更准确合理地选择散热风机,文章以矩形翅片式散热器为例简要分析了强迫风冷散热所需的参考风量;基于散热器结构形式和流体力学原理,推导出散热风道的风阻估算公式;结合对风机P-Q 特性曲线的简要分析,快速得出风机实际的工作点和通风风量。仿真和样机试验结果验证了该估算公式的准确性和有效性。
Abstract:
In order to determine the air resistance of heat sink duct in air-forced cooling for selecting more accurate and reasonable fan, it briefly analyzed the required volume of air-forced cooling by taking the rectangular-fin heat sink as an example and put forward a resistance estimation formula of air duct based on the hest sink structure and the principle of fluid mechanics. Combined with the P-Q characteristic curve of fan, it can quickly get the actual fan operating point and the cooling air quantity. Finally, it validated the accuracy of the formula by using Icepack simulation and prototype measurement analysis.
