三、结构与工作原理Structure and operating principle
Structure of Electric Air Heater
电加热器是由多支管状电热元件、简体、导流板等几部分组成,管状电热元件是在金属管内放入高温电阻丝,在空隙部分紧密地填入具有良好绝缘性和导热性能的结晶氧化镁粉,采用管状电热元件做发热体,具有结构
先进热效率高,机械强度好,耐腐、耐磨等特点。筒体内安装了导流隔板能使空气在流通时受热均匀。
The electric air heater consists of multi tubular heating element, drum, flow deflector and etc. Put the high-temperature resistance wire in the metal tube and tightly fill in the void with crystal magnesia powder, which has the high insulating property and high-thermal conductivity. The tu
