| Abstract: | The influences of the PTCR's characteristic parameters such as switching temperature,room resistance of samples,and dissipation coefficient,etc.on the thermal power of heaters are investigated.In practical pointview,designing the heaters'thermal-electrical parameters reasonably is very impotant.On the basis of the experiments of aging characteristics,factors to enhance the high-power PTC heaters'reliability are disoussed. |
