摘　　要：随着光源技术的发展,UVLED光学元件被广泛应用于各个领域,保证UVLED光学元件的温度在安全范围内至关重要。对应用于UVLED的液冷散热系统进行实验与仿真研究,设计了六边型、直流型、U型、蛇型,四种不同流道的液冷板。在热通量为2.2W/cm^(2)的情况下,实验测试液冷板的换热面温度,并通过数值仿真研究其传热及流动性能。结果表明:实验与仿真结果的相对误差为3%,其中液冷工质为导热油时,六边型流道液冷板的温度分布最均匀且温控效果最好,流量为2.5L/min时,最高温度为49.7℃,直流型流道板面温差最大但压降最低仅为5.34kPa。With the development of light source technology,UVLED optical components are widely used in various fields.It is very important to ensure the temperature of UVLED optical components within a safe range.In this paper,the liquid cooling system for UVLED was studied by experiment and simulation,and four kinds of liquid cooling plates with different flow channels were designed.In the case of heat flux of 2.2 W/cm^(2),the surface temperature and inlet and outlet pressure drop of the liquid cooling plate were tested experimentally,and the heat transfer and flow performance of the liquid cooling plate were studied by numerical simulation.The results show that the relative error between the experimental and simulation results is 3%.When the liquid cooling working medium is heat conduction oil,the temperature distribution of the six-sided flow channel liquid cooling plate is the most uniform and the temperature control effect is the best.When the flow rate is 2.5 L/min,the highest temperature is 49.7℃,and the DC flow channel plate surface temperature difference is the largest,but the lowest pressure drop is only 5.34 kPa.
