【Abstract】 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.更多还原
