222nm准分子光源系统的封闭式循环散热
Closed-loop Heat Dissipation for 222 nm Excimer Light Source System
摘要
Abstract
The KrCl excimer lamp with a peak wavelength of 222 nm has generated widespread attention in recent years due to its potential applications in human-friendly disinfection scenarios.However,the high voltage of the external electrodes of the excimer lamp can generate ozone during operation,which can be harmful to the human body if the ozone concentration is too high in indoor environments.Enclosed excimer luminaire can isolate ozone from the external environment,but they also reduce the heat dissipation efficiency of the lamp,thereby lowering radiation efficiency and affecting the lifespan of the light source.This paper describes the design and fabrication of a closed-loop heat dissipation system for the lamp structure.Simulation calculation and experimental measurements indicate that,compared to a closed-loop naturally cooled lamp,the closed-loop cooling system can reduce reduce the outer tube wall temperature of the lamp from 256℃to 158 ℃ and the inner tube wall temperature from 285 ℃ to 163 ℃.The cooling effect is significant,and the irradiance of the light source increases by more than 17％.关键词
