Abstract

This study performed a steady-state numerical analysis to understand the temperature in different heat sink configurations for LED applications. Seven heat sink configurations named R, H-6, H-8, H-10, C, C3, and C3E3 were considered. Parameters like input power, number of fins, heat sink configuration were varied, and their influence on LED temperature distribution, heat sink thermal resistance and thermal interface material temperature were studied. The results showed that the temperature distribution of the H-6 heat sink decreased by 46.30% compared with the Cheat sink for an input power of 16 W. The result of the H-6 heat sink shows that the heat sink thermal resistance was decreased by 73.91% compared with the Cheat sink at 16 W. The lowest interface material temperature of 54.11 °C was achieved by the H-6 heat sink when the input power was used 16 W. The H-6 heat sink exhibited better performance due to more surface area with several fins than other heat sinks.

大功率LED热管理散热器不同配置的数值模拟

本研究进行了稳态数值分析，以了解LED应用中不同散热片配置的温度。考虑了R、H-6、H-8、H-10、C、C3和C3E3七种散热器配置。研究了输入功率、散热片数量、散热片结构等参数对LED温度分布、散热片热阻和热界面材料温度的影响。结果表明:当输入功率为16 W时，H-6散热器的温度分布比Cheat散热器降低了46.30%;结果表明，在16 W时，H-6散热器的热阻比Cheat散热器降低了73.91%。当输入功率为16 W时，H-6散热器的界面材料温度最低为54.11℃。H-6散热器由于具有多个翅片，比其他散热器具有更大的表面积而表现出更好的性能。
