摘　　要：222 nm准分子灯可应用于人机共存的紫外杀菌应用场景,近年来由于新冠疫情爆发而引起了广泛的关注,具有广阔的应用前景。但由于当前准分子光源系统缺乏有效的热管理设计,导致使用时灯管工作温度很高,从而影响了辐射效率。本文采用并联管路的流量分配模型来分析同轴结构准分子灯内外管壁的散热状态,设计制作了一种双风扇漏斗式灯具散热结构,并通过仿真计算和实验测量的方法与通孔式和单风扇式灯具的散热情况进行了比较。与单风扇式灯具相比,双风扇漏斗式灯具能够在保持内外管壁温度基本一致的同时,使外管壁温度降低78℃,从而使灯具的辐照度提高了10.8%。The 222 nm excimer lamp,which can realize the UV sterilization application scenario of human-machine coexistence,has attracted wide attention due to the COVID-19 pandemic in recent years,and has a broad application prospect.However,due to the lack of effective thermal management design in the current excimer light source system,the working temperature of the lamp tube is rather high,which affects the radiant efficiency.In this paper,the flow distribution model of parallel pipes is used to analyze the heat dissipation state of the inner and outer tube walls of coaxial excimer lamps.A system of double-fan funnel-type heat dissipation structure is designed and manufactured,as well as compared to those of through-hole structure and single-fan structure by means of simulation calculation and experimental measurements.Compared with single-fan system,the new system can reduce the outer tube wall temperature of the excimer lamp by 78℃in the meanwhile keeping the temperature of the inner and outer tube wall basically the same,which can increase the irradiance of the lamp by 10.8%.
