Fan heater is made up of forced draft fan, heater, control circuit three parts, operation principle is as follows: after energising, air blast blow air in heater, air is made evenly to pass through from spiral helicine heating wire medial and lateral, the heat produced after heating wire energising carries out heat exchange with the cold air passed through, thus the wind-warm syndrome of air outlet is raised.The leaving air temp detected is fed back to temperature controller by the thermocouple at air outlet place in time, and instrument according to the actual temperature of the temperature monitoring of the setting work of, and will transmit back solid-state relay and then whether control heater works for information about.According to wind tunnel effect appropriate design, air-out is evenly passed through from spiral heating wire inside/outside side, and rate of heat exchange is high, and air quantity, air loss are few;
Heating wire in fan heater is mostly adopt 2080 nickel filament coilings, and air-out is evenly passed through, and does not produce waste gas and special odor, meets environmental protection.Also be provided with overtemperature protection system, band power-off protection, fully ensures device security simultaneously, annual within 365th, can not stop operation.Under normal circumstances, the maximum operation (service) temperature of fan heater is that scope is at 350 DEG C ~ 650 DEG C.The K type thermocouple be equipped with by air outlet place, is controlled by PID/SSR, and the accurate control of temperature can reach 1 DEG C, and feedback is fast, durable.And regulate motor speed to regulate air quantity by frequency converter can be joined, can accurately grasp temperature and air quantity.
Due in fan heater use procedure, the useful life of heater is the shortest, the situation that heating wire fuses can be first there is under normal circumstances due to the aging of heating wire, now, replacement heat generating core, or directly change fan heater, also there is no that a kind of structure is simple, easily manufactured at present, structure firmly, heating effect is good, and it is special for core that replacing simply adds warm-air pipe.
Summary of the invention
The utility model just for above technical problem, provide that a kind of structure is simple, easily manufactured, structure firmly, the efficiency of heating surface is high, changes that simply to add warm-air pipe special for core.
The utility model realizes mainly through following technical scheme.
Add warm-air pipe for core, comprise fixed leg, insulator cap, core body, tail-hood, hold-down nut, conductive pole, heater strip, head end, tail end, it is characterized in that insulator cap, core body, tail-hood is that pottery is made, be successively set on fixed leg, fixed leg head end expands, tail-hood arranges hold-down nut, hold-down nut is by compressing tail-hood by insulator cap, core body, tail-hood is fixed on fixed leg, tail-hood is matrix near core body one middle side part, core body is provided with multiple through hole, run through core body end to end, core body shaft core position is provided with comparatively large rectangle through hole, all the other through holes are fan-shaped arc and evenly arrangement, insulator cap is provided with conductive pole, heater strip is first from spirally-wound, again successively through the multiple through holes on core body, heater strip two ends are respectively head end, tail end, head end, tail end gives prominence to core body, and be connected with the conductive pole on insulator cap.Be threaded connection between hold-down nut and fixed leg.Fixed leg, hold-down nut are made up of refractory metal.Through hole on core body divides three layers of arrangement, and number of through-holes is respectively 1,6,12.
The fixed leg that the utility model is made by refractory metal and the insulator cap that pottery is made by hold-down nut successively, core body, tail-hood press together, and heater strip is wound on core body that pottery makes, heater strip can be fixed well, heater strip is first from spirally-wound, add the heater strip hardness in manufacturing process, be conducive to processing, turn increase unit volume heater strip length, increase power.And tail-hood is arranged to matrix in the middle of core body side, can not heater strip be urged to when being fixed by hold-down nut, causes the accident of heater strip to rupture, extending useful life.
The utility model structure is simple, and heating wire is ensconced in ceramic cavity with suspension type, and hot blast can pass through from heating wire both sides equably, and air quantity is large, and windage is few, and heating wire temperature is lower.
Accompanying drawing explanation
In accompanying drawing, Fig. 1 is the utility model structural representation, and Fig. 2 is the utility model schematic cross-section, wherein:
