技术介绍
我国大部分地区处于北半球高纬度区域,冬季自然温度较低,人们多采用取暖的办法来抵御寒冬。以前传统的采暖方法是集中供热,由于受到各地方条件限制,集中供暖的推广使用受到很大限制,管道传输造成的热量损失问题一直难以解决,随着社会有限可利用资源的开发,目前整个世界已经陷入了能源危机,造成燃气、煤炭等能源价格飞涨,居民消费支出越来越高,相对降低了国民的生活质量和水平。电力作为一种可再生能源,逐步受到人类的重视,除了工业上的应用,更向着交通、民用领域发展。用于家庭供暖和供水的家用电器正在取代盛及一时的燃气炉,因为燃气不完全燃烧会产生有害气体,使人中毒;一旦燃气热水器或灶具出现故障造成燃气泄露,还会产生爆炸危险;而电力加热器具的优点正在于此。以前使用的储水式电热水器,包括各种敞开式、封闭式,要么采用电热棒直接插入水中作加热元件,要么采用电热盘或陶瓷体传导加热,电热棒时间长了必然积有污垢而使其导热效率降低,而电热盘或陶瓷体一旦超温烧裂,就有可能造成漏电的危险,降低了电热水器的可靠性;其还有一个很大的缺点是热效率低,浪费电能。正鉴于此,现在利用电磁产生涡流的电热器具由于不燃烧,无明火,热效率高,不产生有害气体受到消费者的欢迎。实验证明,电涡流加热的热效率不仅与交变电流的强度成正比,而且还与交变电流的频率成正比,从中频到高频,热效率明显提高。而目前采用传统高频电流发生电路的高频加热装置,多利用于微波炉,还没有发现使用高频电流利用涡流加热的家用热水器和采 ...
