| 摘 要： | 针对大功率LED散热能力较其它照明灯具差这一问题,研制了一种应用在多芯片大功率LED散热上的回路热管装置,并研究了热负荷、倾角等对热管的起动性、均温性和热阻等的影响。试验结果表明,所设计的热管散热器的热阻在0.48～1.47K/W之间;在蒸发器倾斜角为0°和30°时,蒸发器的均温性分别被控制在1.5℃和4.3℃以内。因此,将这种结构的热管应用在大功率LED散热系统中时,首先应该对蒸发器倾斜角度对系统散热性能的影响进行测试评估。

| Abstract: | Compared with other lighting lamps,the thermal problem is still a bottleneck to limit the stability,reliability and lifetime of high-power LEDs.The thermal capabilities,including startup performance,temperature uniformity and thermal resistance of the loop heat pipe used on multi-chip high-power LEDs,under different heat loads and incline angles have been investigated experimentally.The obtained results indicate that the thermal resistance of the heat pipe heat sink is in the range of 0.48-1.47 K/W.The surface temperature difference of the evaporator is controlled nearly within 1.5 ℃ and 4.3 ℃ for 0°and 30° incline angle,respectively.Therefore,the impact of the incline angle of the evaporator on the heat transfer performance of the loop heat pipe should be assessed before such a structure of loop heat pipe is used to cool high-power LED system. |
