摘要

针对大功率LED存在的散热问题，提出了一种双进双出射流水冷散热器，将其与现有射流水冷散热器的散热效果进行对比，并设计了基于射流水冷的大功率LED散热系统实验平台.在散热系统全功率工作条件下，LED底部温度分布均匀，并且保持在32℃左右，表明散热系统具有良好的均温性能和散热性能，满足大功率LED的散热要求.利用极差分析法，得到了水泵和风扇对系统散热效果的影响权重，优化了散热系统的工作功率，得到一组较优的控制水泵和风扇功率的脉冲宽度调制信号.在该组控制信号下，降低了散热系统的功耗，同时保证了系统散热效果，达到了节能目的.

Abstract

For thermal problem existed in high power LED, a new heat exchanger based on double inlets and double outlets water jet was proposed. The different cooling effects between the radiator proposed and the current jet cooling radiator were discussed, an experimental platform of high power LED cooling system base on water jet was designed. Under the condition of full power output of the cooling system, the LED substrate′s temperature is distributed and remained at 32℃ in experiment, which shows that the cooling system has excellent abilities in uniforming temperature and distributing heat which the LED produced. And the experiment proves that the system meets the thermal requirements of the high power LED. The effect weights of the pump and the fan were obtained and the consumption power of the cooling system was optimized by using extremum difference analysis. Besides, a set of optimum pulse width modulation signals controlling pumps and fans were obtained through the experiments and analysis. The power consumption of the cooling system was reduced and the energy was saved with these signals.
