  • 加热管结构示意图及原理

    2015年11月22日 by admin

    今天特耐佳电热管为客户解释一下加热管的原理及结构示意图展示:

    加热管就是金属管里面有电阻丝,和电炉丝是一样。发热原理,电流通过电阻要产生热量。具有使用寿命长、电热转换效率高、远红外线辐射、健康环保等优异性能。
    根据电热定律:发热量正比于电流平方与电阻之乘积。 电流热效应原理:电子在电场中得到加速,获得动能,具有速度,然后碰撞其他的微粒(原子,分子,原子团)使其他的微粒获得动能,导致平均动能增大,温度升高。 焦耳-楞次定律: 电流通过电阻时,电阻就会发热,将电能转换为热能,这种现象叫做电流的热效应。 焦耳和楞次通过大量的试验,发现电阻通过电流后所产生的热量与电流的平方、电阻及通电时间成正比。这就是是焦耳-楞次定律。以上信息希望对客户有帮助。

    Heat pipes is metal tube inside resistance wire and electric stove wire is the same. Heating principle, the current through the resistance to heat. Has a long service life, high electric conversion efficiency, excellent performance such as far infrared ray radiation, healthy environmental protection.

    According to the law of electric: calorific value is proportional to the current square and the resistance of the product. Current heating principle: electronic accelerated in the electric field, gain kinetic energy, has the speed, then the collision of other particles (atoms, molecules, atoms) give other particle kinetic energy, lead to the average kinetic energy increases, the temperature rise. Joule - lenz's law: an electric current passes through the resistance, the resistance will be fever, converts electrical energy into heat energy, this phenomenon is called the heating effect of the current. Joule and lenz through a large number of trials, found that the heat generated by the resistance by the current and the square of the current, resistance, and is proportional to the current time. This is what is the joule - lenz's law.
