前言 家用电暖器近年来在我国发展很快,虽然该类产品有多种结构型式,但是,它们一般都是以对流换热为主,散热体表面温度通常在80℃以下,散热面积较大。远红外石晶管电暖器于上述产品不同,其发热管表面温度高达600℃以上,它是以辐射换热为主。由于其体积小,重量轻,价格便宜,应用范围较广,但其缺点是:辐射面小,人感觉不舒服、安全性也较差。针对上述问题,我们拟定研究一种新型可悬挂式家用辐射电采暖器。使其结构简单、经济可行,使用安全可靠,在散热片上用彩色辐射涂料绘制了彩画,即是采暖器又是工艺品。
Foreword Household electric heaters have developed rapidly in China in recent years. Although there are many structural types of such products, they are generally based on convection heat transfer. The surface temperature of the heat sink is usually below 80°C, and the heat dissipation area is relatively small. Big. The far-infrared quartz crystal tube heater is different from the above products in that the surface temperature of the heating tube is up to 600°C or more, and it is based on radiation heat exchange. Because of its small size, light weight, low price, and wide range of applications, its disadvantages are: small radiation surface, people feel uncomfortable, and safety is also poor. In view of the above problems, we have proposed to study a new type of household radiator electric radiator. Its structure is simple, economical and feasible, and it is safe and reliable to use. Colored paint is painted on the heat sink with a colored radiation coating, that is, a heater and a handicraft.
