技术介绍
现有的电加热装置一般都采用金属丝电热体发热,如镍铬合金、钼丝、钨丝等,但是一般的金属加热丝在加热高温下易氧化,在高温下强度低,元件变形、易击穿、不易修复。碳纤维是一种新兴的纯黑体电热材料,电热转换效率达95%以上,比镍铬、钨钼等材料作为发热体的加热器节能30%,在相同功率下,比镍铬金属电热管辐射温度高30℃,比钨钼丝石英电热管高15℃。现有的碳纤维加热器通常被制成碳纤维石英加热管,其包括石英管本体,石英管本体的两端经压扁后分别形成压头,压头将石英管本体的两端密封,密封的石英管本体内充有惰性气体,在密封的石英管本体内分别设置有碳纤维加热丝、与碳纤维加热丝两端相连接的电极、分别与两电极另一端相连接的钼杆,两钼杆的另一端分别通过设置在两压头内的钼片与外接导线相连接,碳纤维加热丝设置在石英管本体内的加热区内,电极和钼杆设置在石英管本体内的冷却区。由碳纤维石英管制成的加热盘受管径所限无法做成平面薄板型加热板,由碳纤维石英管弯曲做成的加热盘整体强度较低,容易破裂失效,给产品的运输、安装带来困扰。技术申请201120034101.2一种高效的多功能红外辐射器,通过对该专利申请的说明书第0027段的阅读可知,发热体采用的是电加热管,更确切地讲,是以电热丝作为发热源。由于电热丝发热时的温度较高,因而需要进行多层隔热与保温,同时对相关元件的择用也提出了较高的耐温与耐火要求。上述专利的红外辐射板是以铝型材作为基板,使用温度受到铝材的熔点限制,工作温度会限制在 ...
