The ribbon heater of concavo-convex zone face can use hydraulic die disposal molding, and the design of this zone face can be in surface temperature Degree still keeps certain rigidity when reaching 1100 degree of high temperature, will not produce bending or lodging.

Further, the outer wall of described heating furnace body 4 is provided with in interface, described interface and three described passages 5 Multiple described electrothermal module 6 be connected；

The current output terminal of described high voltage power supply output counter is provided with joint, described joint and described interface grafting.

The circuit of electrothermal module 6 is all arranged at intracranial, convenient dismounting and replacing, in module between ribbon heater and ribbon heater all Connected by high temperature resistant heat-resisting wire.The ribbon heater of modular member is all connected by dismountable joint.Certainly, joint is also adopted by resistance to High temperature joint.

It is positioned at three ribbon heaters of end, is then introduced by connecting line and outside heating furnace body 4, cassette jack, high-tension electricity are set A, B, C three phase mains of source output counter 13 inserts cassette jack respectively, just can safe power supply.

For this device is from structure and operation characteristic, neither boiler is not the most pressure vessel, not yet done special equipment pipe Linchpin scope, it is not necessary to supervision, safe and reliable.Use Forced Air Convection cooling technology, so electric heater surface temperature exists all the time Run at safety, rational temperature, thus heater is long for service life, can reach more than 20 years service life.This device simultaneously Use electricity and heat storage blocks 10 separated heating technology, heat for carrier with insulation torrefaction air, so any position of this device is the most not Electrification phenomenon can be attended, thus this apparatus for safety protection is scientific and reasonable, safe and reliable, the most not entail dangers to human body peace Entirely.Hot water supply system either requires temperature regulation or Flow-rate adjustment, all can be followed with being increased or decreased by variable frequency adjustment The air quantity of ring blower fan, reaches to be automatically adjusted the purpose of heating load according to outdoor temperature.

Last it is noted that various embodiments above is only in order to illustrate the technical solution of the utility model, rather than it is limited System；Although being described in detail this utility model with reference to foregoing embodiments, those of ordinary skill in the art should Understand: the technical scheme described in foregoing embodiments still can be modified by it, or to the most some or all of Technical characteristic carries out equivalent；And these amendments or replacement, do not make the essence of appropriate technical solution depart from this practicality new The scope of type each embodiment technical scheme.
