The advantages such as high-heating radiation effect, low operating temperature and installation process are easy, are widely used in the electric heating field of building.
At present, existing tabular electric heater mainly has a following two structure:
The first structure: using carbon fiber paper as heating core, using copper foil tape as conductive electrode, with dipped glass fibre cloth
As insulant, become lamellar thermo electric material with pressure processing through uniform temperature；Then by this lamellar thermo electric material with every
Hot material and passive framework are combined with each other, thus make tabular electric heater.But the tabular electricity of this structure adds

To higher, and higher operating temperature can aggravate the increase of contact resistance, therefore under the duty of long-term big load,
This vicious cycle can make the safe condition of this tabular electric heater increasingly deteriorate and be difficult to predict security risk.
The second structure: with carbon fiber heating line, lectrothermal alloy wire, electrothermal alloy foil for heating core, stick with glue agent solid
Due to metal decking, then coated with heat-barrier material, thus make tabular electric heater.But the tabular electric heater of this structure is extremely
Have the disadvantage in that the tabular electric heater of the most this structure is sent out owing to heating core is all belonging to wire exothermic material less
Hot Relatively centralized, the thermal efficiency are low, and the cold and hot end of electrode connection is difficult to smooth transition, easily aging because of long-term overheat.
Additionally, the leakage current problem produced because of capacity effect is not paid attention to, therefore by the tabular electric heater of this structure
