Thermal Characteristics of Gas-controlled Sodium Heat-pipe Furnace

  • 摘要: 为探索气控热管在计量领域的应用,研究气控钠热管炉热特性.在未控压的状态下,找出加热炉最佳控温点,研究气控钠热管在同一温度计阱不同位置上和不同温度计阱中的温度稳定性和温度场均匀性,对加热炉丝2种不同的绕制方式进行讨论.实验结果表明,将热管内温度控制在655℃、气路压力控制在7.840 kPa的状态下,热管温度稳定性在15 min内达到±0.836 4 mK.
    Abstract: To explore the application of the gas-controlled heat-pipe in metrology,the thermal characteristics of the gas-controlled sodium heat-pipe furnace is researched.The best temperature control position of the furnace is found without pressure control,the temperature stability and uniformity both in the single thermometer well and among different thermometer wells are studied,and two different winding modes of heating wires are discussed.Experimental results show that the temperature stability reaches ±0.836 4 mK within 15 min,controlling heat-pipe inner temperature at 655 ℃,and the gas line pressure at 7.840 kPa.
