空气加热器(又名散热器或散热排管)是以冷热媒介进行冷却或加热空气的换热装置中的主要设备，通入高温水，蒸汽或高温导热油可以加热空气，通入盐水或低温水哭冷却空气，因此她可以广泛用在轻工、建筑、机械、纺织、印染、电子、食品、淀粉、医药、冶金涂装等各种行业中的热风采暖、空调、冷却、冷凝、除湿、烘干等。

        Air heater (also known as radiator or radiator exhaust pipe) is the main equipment in the heat exchanger which cools or heats air with cold and hot medium. It can be heated by high temperature water, steam or high temperature heat conducting oil, and cooled by brine or low temperature water. Therefore, it can be widely used in light industry, construction, machinery, textile and printing. Hot air heating, air conditioning, cooling, condensation, dehumidification and drying in various industries such as dyeing, electronics, food, starch, medicine, metallurgical coating, etc.

     空气加热器主要是用来将所需要的空气流从初始温度加热到所需要的空气温度，可高达600℃。已被广泛的应用到航空航天、兵器工业、化工工业和高等院校等许多科研生产试验室。特别适合于自动控温和大流量高温联合系统和附件试验。空气加热器使用的范围宽：可以对任何气体加热，产生的热空气干燥无水份、不导电、不燃烧、不爆炸、无化学腐蚀性、无污染、安全可靠、被加热空间升温快(可控)。空气散热器广泛用于化工，医药等行业，整齐温度高，耐腐性好，安装方便，经久耐用。空气散热排管是一种标准型号的散热排管，适用于蒸汽加热系统，因其进出水接头分置于排管两侧，所以采用曲管来消除受热膨胀及其它原因所造成的应力。

      Air heater is mainly used to heat the required air flow from the initial temperature to the required air temperature, up to 600 degrees Celsius. It has been widely used in many scientific research and production laboratories, such as aerospace, weapon industry, chemical industry and universities. It is especially suitable for automatic temperature control and large flow high temperature combined system and accessories test. Air heater can be used in a wide range: any gas can be heated, resulting in hot air drying no moisture, no conductivity, no combustion, no explosion, no chemical corrosiveness, no pollution, safe and reliable, heating space quickly (controllable). Air radiator is widely used in chemical industry, medicine and other industries. It has high temperature, good corrosion resistance, easy installation and durability. Air radiation exhaust pipe is a standard type of radiation exhaust pipe, which is suitable for steam heating system. Because the inlet and outlet water joints are located on both sides of the exhaust pipe, curved pipe is used to eliminate the stress caused by thermal expansion and other reasons.
