提出LED灯的液体金属散热新方法,并研制出基于电磁泵(EP)驱动的散热系统原型。实验结果表明:在LED灯的输入功率达到25.7 W时,液态金属散热系统可将其基座温度维持在33.1℃,从而确保LED芯片安全运行。评估了EP输入功率、肋片及风扇对液态金属散热系统散热效果的影响。
A novel liquid metal cooling method for LED light is proposed.A prototype system driven by an electromagnetic pump is developed.According to the experiments,when the input power of LED light reaches 25.7 W,the liquid metal cooling system still maintains its base temperature at 33.1 ℃,which ensures the safe running of the LED chip.The impact of the input power of the electromagnetic pump and the surface size of the fin and fan on the heat dissipation performances of the system is further evaluated.
