摘要
主要研究了ＰＴＣ材料的开关温度、样品的室温电阻及耗散系数等特性参数对发热体功率的影响。从实用的角度阐述了合理设计发热体各种电热参数的重要性。在对ＰＴＣ发热体进行的老化试验的基础上，探讨了提高ＰＴＣ大功率发热体可靠性的因素。
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.
