Heat Conduction
Heat transfer is the process of transferring heat from high temperature to low temperature. It is the result of the transmission of vibrational energy from one molecule to another. Various materials of different thermal conductivity, good conductivity, such as metal, but also includes the movement of free electrons, so the heat transfer speed, you can do heat exchanger materials, and metal conduction capacity followed by silver\u003e copper\u003e gold\u003e aluminum ; Conduction performance is not good, such as asbestos, you can do thermal insulation materials. ...
