背景技术Background technique
目前，多数电加热管内部电热丝都是螺旋式的结构，热辐射面积和热交换面积小，热交换的效率不高；此外，加热管的电极大都采用两端连接，使用时，如果在加热液体或者蒸汽时，封闭性不好会导致液体和蒸汽泄露，同时也会导致电源的短路以及电源连接不便等问题。At present, the electric heating wire inside most electric heating tubes has a spiral structure, the heat radiation area and heat exchange area are small, and the heat exchange efficiency is not high; in addition, the electrodes of the heating tube are mostly connected at both ends.
