摘要
<p>The radiator comprises of plastic modules arranged in its interior with refractory cement for absorbing electrical resistance. A part at the center of the radiator is formed with a hollow space for airflow or air convection. An upper grid and a bottom grid are arranged to ensure natural air convection due to difference in densities caused by temperature difference.</p>
