一种基于PTC陶瓷材料的汽车电饭煲

Electric Cooker Based on PTC Ceranics

介绍了PTC效应和常用PTC陶瓷材料。介绍了PTC陶瓷材料的电阻-温度特性、电压-电流特性和电流-时间(动态)特性等基本特性。根据PTC陶瓷材料的基本特性,可以将PTC陶瓷材料作为电饭煲的加热材料,它的特性十分符合电饭煲的加热要求。介绍了一种基于PTC陶瓷材料作为加热元件的新型汽车电饭煲,对汽车电饭煲的结构、工作原理和性能特点等进行了讨论。

The paper introduces the common china material and the domino effect of PTC, along with the basic features of resistance and temperature; voltage and electric current; time and electric current.According to its basic feature,china material of PTC can be used as the heating material of electric cooker,because its features can meet the heating requirements of electric cooker.A new type of electric cooker equipped in an automobile is also introduced,and its structure,and working principle and feature are also discussed in the paper.
