摘要
红外相机工作环境温度不能超过50℃,但在某些工业高温场合,它需在约300℃的环境中持续工作。针对此问题,设计一种适用于某型号红外相机的三态隔热冷却装置。该装置结合隔热材料阻滞热量传递、水冷却、空气冷却的三态物质的隔热冷却效果,同时具有自清洁石英玻璃的作用。通过COMSOL中的传热模块对传热性能进行验证,分析其内部空间的温度场。结果表明:所设计的三态隔热冷却装置能够在约300℃的环境温度下使红外相机所处空间的温度保持在50℃以下,保证红外相机能正常工作。
Infrared camera working environment temperature cannot exceed 50℃,but in some industrial high temperature occa⁃sion,it needs to continue to work at about 300℃environment.Aiming at this problem,a three-state heat insulation cooling device for a certain type of infrared camera was designed.The device had the three-state matter thermal insulation cooling effect including the heat insulation block transmission,water cooling,air cooling heat cooling,at the same time,it had the function of self-cleaning quartz glass.The heat transfer performance was verified through the heat transfer module in COMSOL,and the temperature field in the inter⁃nal space was analyzed.The results show that by using the designed three-state heat insulation cooling device,the temperature of the infrared camera can be kept below 50℃under the ambient temperature about 300℃,and the normal operation of the infrared camera can been sured.
