For reaching above object, the utility model adopts following technical scheme.
With type of taking out a by force gas heater for direct current generator, comprising: burner, the heat-exchanger rig be communicated with burner, the fume extractor be communicated with heat-exchanger rig, motor fume extractor being provided with smoke evacuation wind wheel and being connected with smoke evacuation wind wheel; It is characterized in that, described motor is direct current generator, output one and output two is extended with respectively at the two ends of direct current generator, described output one is connected with smoke evacuation wind wheel, described output two turns with radiating wheel and is connected, the circuit board of direct current generator be positioned at away from smoke evacuation wind wheel side, turn corresponding with radiating wheel.
Further illustrating as such scheme, described output one and output two are the two ends of same output shaft.
Further illustrating as such scheme, turns outer at radiating wheel and is provided with ventilation protective cover.
Further illustrating as such scheme, described fume extractor comprises: exhaust fume collecting hood, is arranged on the spiral case on exhaust fume collecting hood; Described Smoke wheel is positioned at spiral case, described DC fan by support installing on spiral case.
Compared with prior art, the utility model provides a kind of type of taking out by force gas heater with direct current generator to have following beneficial effect:
One, because circuit board has been placed on away from spiral case side, increase the distance of circuit board and high temperature spiral case, and the spiral case of circuit board and high temperature by electric machine casing and motor winding isolate, effective reduce heat radiation that high-temperature flue gas produces to the impact of circuit board.
Two, turn by installing radiating wheel additional in circuit board side, radiating wheel turns to be fixed with motor shaft, and along with motor in synchrony rotates, the rotation that radiating wheel turns can the rapid air movement that encloses of driven wheel turn-week, the air-flow of flowing takes away heat, reaches the effect reducing circuit board temperature rise.

Detailed description of the invention
For setting forth essence of the present utility model further, by reference to the accompanying drawings detailed description of the invention of the present utility model is described as follows.
As shown in Figure 1 and Figure 2, with type of taking out a by force gas heater for direct current generator, comprising: burner, the heat-exchanger rig be communicated with burner, the fume extractor 1 be communicated with heat-exchanger rig, the motor 3 fume extractor 1 being provided with smoke evacuation wind wheel 2 and being connected with smoke evacuation wind wheel 2.
Described fume extractor 1 comprises: exhaust fume collecting hood 11, is arranged on the spiral case 12 on exhaust fume collecting hood 11; Described smoke evacuation wind wheel 2 is positioned at spiral case 12, and described motor 3 is arranged on spiral case 12 by support 6.
Described motor 3 is direct current generator, output 1 and output 2 31 is extended with respectively at the two ends of direct current generator, described output 1 is connected with smoke evacuation wind wheel 2, described output 2 32 turns 4 with radiating wheel and is connected, and the circuit board 33 of direct current generator is positioned at away from the side of smoke evacuation wind wheel 2, turns 4 corresponding with radiating wheel.
