Description
Technical field
The present invention relates to a kind of heating tube, in particular to a kind of electric heating tube with function of temperature control.
Background technique
Electric heating tube is widely used in the fields such as electric boiler, hot-water heater, air conditioner auxiliary heater.With modern electric
The development of industry, it is also higher and higher for the performance requirement of electric heating tube.Existing product just uses four hole magnesium globule of primitiveness, double
Road or four road heater strip techniques.Pipe diameter is big, at high cost, and heating tube fever is uneven, and long-time service incrustation is serious, causes to dissipate
Heat is bad, and the time, which is not grown, is easy for booster, buries security risk.
And present old money heating tube, without temperature control device, some meeting dehydrations will lead to dry combustion method.Wiring position uses 250
Type inserted sheet, in security performance there are hidden danger, contact performance is bad.Short circuit is sometimes resulted in, is easily caused danger.
Summary of the invention
To overcome the shortcomings of existing technologies, the purpose of the present invention is to provide a kind of electric heating tube with function of temperature control,
This kind of heating tube fever is uniform, it is not easy to which incrustation, long-time service can also provide high thermal effect, and built-in temperature controller, power saving safety.
The present invention solves technical problem and adopts the following technical scheme that
A kind of electric heating tube with function of temperature control, wherein including heating tube body, the heating pipe end is provided with certainly
Dynamic temperature controller, the automatic thermostat includes temperature sensing instrument and switch controller, and the temperature sensor is connected to heating tube
Body bottom portion, the temperature sensor realize the connection between switch controller by electric wire；The heating tube body exterior
It is wound with heating heating wire group, the heating wire group includes two heating wires, respectively the first heating wire and the second heating wire, institute
Stating the first heating wire is nichrome wire；Second heating wire is graphene heating wire, the second heating wire external spray
There is a high temperature magnesium powder layer, it is external that first heating wire with the second heating wire is uniformly looped around heating tube sheet in parallel double-helix
Portion；Insulating protective layer is equipped with outside the electric heating tube, the insulating protective layer is the insulation for being sprayed on heating tube body exterior
Paint layer, the insulating protective layer with a thickness of 0.5-1mm；The ratio between the first heating wire diameter L1 and the second heating wire diameter L2
For 4:1.
Above-mentioned a kind of electric heating tube with function of temperature control, wherein the electric heating tube diameter L3 and the first electric heating wire
Diameter ratio is 5:1.
Compared with the prior art, the beneficial effects of the present invention are embodied in:
Surface loading increases, and electric heating tube diameter reduces, and heating wire bore overstriking improves the thermal effect of pipe, do not allow
Easy incrustation.The surface loading of pipe can reach between 10-20W.Based on high temperature silk and high temperature magnesium powder, add heating wire diameter
Slightly, change original two-way and four roads silk.Be changed to mariages increase wrapping wire plug, allow between heater strip and the inner wall of pipe reach compared with
Good insulating layer, improves thermal effect.
By secondary scientific experimentations up to ten thousand and calculating, when the ratio between the first heating wire diameter L1 and the second heating wire diameter L2 are 4:
1, and when electric heating tube diameter L3 and the first electric heating wire diameter ratio are 5:1, the insulation effect and thermal effect of electric heater are imitated
Fruit is best.
Temperature compared to common external temperature controller measurement is the temperature of the external equipments such as radiator or electric boiler
Degree, the emphasis that the present invention measures is the temperature of internal heating tube, avoids security risk, contact performance is good.Prevent short-circuit conditions
Occur, avoids danger.
