摘要
应用于油墨固化领域的UV固化灯常采用密集阵列排布的UV-LED模组作为高辐射高能量的光源,而高能量的UV固化灯对其散热器的结构设计提出很高的要求。本文结合数值模拟与实验,提出一种基于强制风冷的热管式散热器,通过理论计算证明该散热器结构的可行性,研究了300~1500 W功率下基板温度变化情况,对比分析了不同抽风量与散热片数量下热源基板温度变化情况,得出抽风量7 m^3/min、散热片数量为35片时散热效果最佳。实验所测结果与仿真结果误差为4%,证实了仿真结果的准确性,对大功率UV固化灯风冷散热器设计具有参考价值。
UV curing lamps applied in the field of ink curing often use a dense array of UV-LED modules as a high-radiation and high-energy light source,and high-energy UV curing lamps place high requirements on the structural design of their heat sinks.This paper combines numerical simulation and experiments to propose a heat pipe radiator based on forced air cooling.The feasibility of the structure of the radiator is proved by theoretical calculations.The temperature variation of the substrate under 300 W to 1500 W power is studied,and different air extraction volumes are compared and analyzed.According to the change of the temperature of the heat source substrate under the number of heat sinks,it is concluded that the heat dissipation effect is best when the amount of exhaust air is 7 m3/min and the number of heat sinks is 35.The error between the experimental results and the simulation results is 4%,which confirms the accuracy of the simulation results and has reference value for the design of high-power UV curing lamp air-cooled radiators.
