Description

蜂窝陶瓷电热膜元件
技术领域
本实用新型属于以材料成分为特征的欧姆电阻发热器件，特别涉及一种在蜂窝陶瓷板上喷涂电热膜的蜂窝陶瓷电热膜元件。
背景技术
目前，市面上的暖风机、电吹风等电热器具，主要采用合金电热丝作为发热元件，电热丝电热转换效率较低，线状散热，散热面积小，出口风燥热。近年，将PTC电热元件应用于暖风机、电吹风已有生产，其电热转换效率较高，通过铝片散热使散热面积增大。但从使用情况看，有的PTC高温稳定性不够，PTC本身为块状元件发热，靠铝片转换换热，散热效率要打折扣，需要一种有远红外辐射、对人体有益、能直接散热、电热转换效率及散热效率都高、性能更稳定的蜂窝陶瓷电热膜元件。但现有蜂窝陶瓷电热膜元件的电极连接方式不够合理，交流电压220V下的方块电阻太大，方块电阻很难做到均匀，不能批量生产，而且衰减太快，性能不稳定。
发明内容
本实用新型的目的是，设计一种蜂窝陶瓷电热膜元件，将电热膜制备在蜂窝陶瓷板上，由蜂窝陶瓷板的内孔和表面发热。改变电极连接方式，克服现有蜂窝陶瓷电热膜元件的方块电阻太大的缺陷。
本实用新型的技术方案是，一种蜂窝陶瓷电热膜元件，由蜂窝陶瓷板、电热膜、电极组成，将电热膜高温喷涂在蜂窝陶瓷板的内孔和蜂窝陶瓷板表面上，蜂窝陶瓷板的两个对边涂银浆作为电极，通电后，蜂窝陶瓷板内孔和蜂窝陶瓷板表面发热。如上所述的蜂窝陶瓷板，其蜂窝陶瓷板正面和蜂窝陶瓷板底面各一个对边涂银浆作为电极。如上所述的蜂窝陶瓷板的内孔为贯通孔，贯通孔形状为圆形、或方形、或六边形。
本实用新型的优点是，采用电热膜技术，电热转换效率高；采用蜂窝陶瓷板作为发热载体，直接散热，无须借助其他金属散热，散热效率更高；多孔蜂窝陶瓷内孔表面积大，单位面积发热功率小，电热性能稳定。蜂窝陶瓷电热膜元件的电极连接方式合理，交流电压220V下的方块电阻小而均匀，易于批量生产，性能稳定。适用于蜂窝陶瓷电热膜元件。
附图说明
以下结合附图及实施例，对本实用新型做进一步描述。
图1是本实用新型的蜂窝陶瓷电热膜元件的构造示意图。
图中，1-蜂窝陶瓷板，2-电热膜，3-银电极，4-贯通孔
具体实施方式
由图1可见，本实用新型的的蜂窝陶瓷电热膜元件，由蜂窝陶瓷板、电热膜、银电极组成，将电热膜(2)高温喷涂在蜂窝陶瓷板(1)的内孔和蜂窝陶瓷板表面上，蜂窝陶瓷板的内孔为贯通孔(4)，蜂窝陶瓷板的两个对边涂银浆作为电极(3)，蜂窝陶瓷板是堇青石或莫来石材质的蜂窝陶瓷板，电热膜是氧化锡电热膜，银电极是中、高温银浆高温还原而成。
本实用新型的使用方法是，将蜂窝陶瓷电热膜元件固定在暖风机电吹风壳中，接通风机电源，再接通蜂窝陶瓷电热膜元件电源，电热膜产生热量被风吹出，即可达到暖风效果。
