摘　　要：从取样探头位置着手,设计由冷风和冷却水两种对高温样品气进行前级冷却装置。水冷系统是在取样探头处通过冷却循环水对样品气进行一级降温的装置,而风冷系统是通过涡旋制冷管对样品气进行冷风降温的装置。新型冷却系统,可达到更好的降温目的,从而延长分析仪器的使用寿命,降低维护成本,有效确保进入分析仪器中的样品气符合测量要求,大大延长了分析仪器的使用寿命。This paper designs the front-stage cooling device for high-temperature sample gas by cold air and cooling water.The water cooling system is a device that cools the sample gas by cooling the circulating water at the sampling probe,the air cooling system is a device that cools the sample gas through the vortex refrigeration tube.The new cooling system can achieve better cooling purpose.Thus,the service life of the analytical instrument is prolonged,the maintenance cost is reduced,Effectively ensure that the sample gas entering the analyzer meets the measurement requirements,the service life of the analytical instrument is greatly prolonged.
