Problems solved by technology
The diameter of the tube is large, the cost is high, the heat of the heating tube is uneven, and the fouling is serious after long-term use, which leads to poor heat dissipation, and the tube is easy to burst after a short period of time, burying potential safety hazards
[0003] And now the old heating tube does not have a temperature control device, some will dehydrate, which will lead to dry burning
The wiring part adopts 250-type inserts, which has hidden dangers in safety performance and poor contact performance
Sometimes it can cause a short circuit, which is dangerous

Description
technical field [0001] The invention relates to a heating tube, in particular to an electric heating tube with a temperature control function. Background technique [0002] Electric heating tubes are widely used in electric boilers, hot water heaters, auxiliary heaters for air conditioners and other fields. With the development of the modern power industry, the performance requirements for electric heating tubes are getting higher and higher. The existing products only use the original four-hole magnesium beads, two-way or four-way heating wire technology. The diameter of the tube is large, the cost is high, the heating tube heats up unevenly, and the fouling is serious after long-term use, resulting in poor heat dissipation, and the tube is easy to burst after a short period of time, burying potential safety hazards. [0003] And the current old heating tubes do not have a temperature control device, and some will be dehydrated, which will lead to dry burning. The wiring...
