Abstract: The invention is directed to an air heater for a gas chromatograph. The air heater has a core disposed inside a housing and includes an electrically resistive heating element. An air passage in the core extends parallel to a central axis of the air heater. A conduit extends parallel to the central axis of the air heater and is disposed farther outward from the central axis of the air heater than the air passage of the core. The conduit is connected between an air flow inlet and the air passage in the core such that when the air flow inlet is connected to an air source, air from the air inlet flows through the conduit to the air passage in the core and thence through an air flow outlet of the air heater. The air flowing through the conduit is cooler than the air flowing through the air passage in the core.

Abstract translation: 本发明涉及一种用于气相色谱仪的空气加热器。 空气加热器具有设置在壳体内部并具有电阻加热元件的芯体。 芯体中的空气通道平行于空气加热器的中心轴延伸。 导管平行于空气加热器的中心轴线延伸并且比空气通道更远离空气加热器的中心轴线。 导管连接在空气流入口和核心中的空气通道之间，使得当空气流入口连接到空气源时，来自空气入口的空气通过导管流过核心中的空气通道，然后通过 空气加热器的气流出口。 流过导管的空气比流经核心中的空气通道的空气更冷。
