轴向波折形笼(俗称鼠笼式)柜式电热辐射管其结构是将加热元件的电阻丝(带)弯成“U”形串入多块绝缘耐高温的圆形、方形陶瓷支撑盘中,中间用一根耐热棒固定,其功率可达5-16.5KW。这种辐射管寿命较长;线装螺旋环绕电热辐射管,这种电热辐射管由耐热合金钢套管和加热器组成,加热器一般由φ3-5 mm电热丝绕在开有螺旋沟槽的耐热绝缘陶瓷管芯上,工作电压220V、功率一般5-7KW。带状螺旋环绕电热辐射管,这种电热辐射管的结构基本上与第一种结构相同,只是加热元件采用电阻带绕制,电阻带一般厚度为1-3 mm,宽度10-20 mm,管芯也多为多个分组式管芯组成,在同样表面负荷下,热辐射面大,材料可节省,一般大功率点加热辐射管采用此种形式。

Axial twists and turns cage (commonly known as cage) cabinet electric radiant tube电热辐射管 which is the resistance wire heating element (belt) is bent into a “U” shape on a plurality of insulation in circular, square of high temperature ceramic support plate, the middle with a heat rod is fixed, the power of up to 5-16.5KW. This radiation pipe life is longer; wire spiral electrothermal radiation tube, the electric heating tube is composed of a heat resistant alloy steel casing and a heater, the heater by φ 3-5 mm electric heating wire is wound in a spiral groove heat insulating ceramic tube core, working voltage 220V, power 5-7KW. Ribbon spiral electric radiant tube, the electric heating tube structure is basically the same with the first structure, only the heating element adopts a resistance belt winding resistance with thickness of 1-3, width mm, 10-20 mm, the tube core is a plurality of packet type pipe core, in the same surface load, thermal radiation large, material can be saved, large power heating radiant tube 电热辐射管with this form.
