Description
Technical Field
The utility model belongs to the technical field of diesel generator, especially, relate to an induced air device of forced air cooling diesel generator.
Background
The air-cooled diesel engine belongs to a medium-high speed engine, and adopts an air-cooled single-cylinder diesel engine as a power generator set. In order to solve the heat dissipation problem, the structure shown in fig. 1 is adopted, the heat dissipation blowing fan 2 is arranged at the front end of the box body 1, and cold air is blown to the air cooling channel 4 of the diesel engine 3 and the generator 5 at positive pressure, so that the diesel engine 3 and the generator 5 are cooled. However, a large part of the cold air sent by the heat-dissipating blowing fan 2 can be scattered to enter other spaces in the box body 1 before entering the air-cooling channel 4, so that the amount of the cold air entering the air-cooling channel 4 is reduced, and the cooling efficiency of the diesel engine 3 and the generator 5 is reduced.
Disclosure of Invention
The utility model aims at providing an induced air device of forced air cooling diesel generator to the not enough of above-mentioned prior art existence.
The utility model adopts the technical proposal that: an air inducing device of an air-cooled diesel generator comprises a box body, a generator and a diesel engine, wherein an air-cooled channel is arranged on the diesel engine, the generator is opposite to the tail end of the air-cooled channel, a rotor rotating shaft of the generator is in transmission connection with an output shaft of the diesel engine, and a heat dissipation blower opposite to the front end of the air-cooled channel is arranged at the front end of the box body; and an induced draft barrel is connected between the heat dissipation blowing fan and the front end part of the air cooling channel.
The generator upper shield is provided with an exhaust hood, the side wall of the exhaust hood is provided with a plurality of exhaust pipes communicated with the inner cavity of the exhaust hood, the pipe orifice of each exhaust pipe is connected with a hose, and the air outlet of each hose is arranged on the outer side of the box body.
The plurality of exhaust pipes are spirally and uniformly arranged anticlockwise or clockwise.
After the structure is adopted, compared with the prior art, the utility model the advantage that has is: the utility model discloses an induced draft barrel physical stamina directly guides the cold wind of seeing off of fan of blowing of dispelling the heat to air-cooled passageway and carries out the forced air cooling heat dissipation to diesel engine and generator, has avoided the loss of the amount of wind, improves cooling efficiency.

Detailed Description
The following description is only for the preferred embodiment of the present invention, and the protection scope of the present invention is not limited thereby, the present invention will be further explained with reference to the drawings and the embodiments.
Examples, see fig. 2-3: the utility model provides an induced air device of forced air cooling diesel generator 5, includes box 1, generator 5 and diesel engine 3, is equipped with forced air cooling passageway 4 on the diesel engine 3, and the tail end of generator 5 and forced air cooling passageway 4 is relative, and the rotor spindle of generator 5 is connected with the output shaft transmission of diesel engine 3, and box 1 front end is equipped with the heat dissipation hair-dryer 2 relative with the front end of forced air cooling passageway 4. An induced draft barrel 6 is connected between the heat dissipation blowing fan and the front end part of the air cooling channel 4. The air inducing cylinder 6 can directly guide the cold air sent out by the heat dissipation blowing fan to the air cooling channel 4 and perform air cooling heat dissipation on the diesel engine 3 and the generator 5, so that the loss of air volume is avoided, and the cooling efficiency is improved.
The cold air is formed into hot air after radiating heat of the diesel engine and the generator 5, at present, the ventilation shutter is arranged on the side wall of the box body 1 to discharge the hot air, but before the hot air is discharged out of the box body 1 from the ventilation shutter, the hot air can diffuse the inner space of the whole box body 1 due to the blocking of the box wall and the like, so that the cooling effect of the diesel engine and the generator 5 is greatly reduced. Therefore, the utility model discloses generator 5 is covered and is established exhaust hood 7, the lateral wall of exhaust hood 7 is equipped with the exhaust pipe 8 of 7 inner chambers of a plurality of intercommunication exhaust hood, the mouth of pipe of exhaust pipe 8 is connected with hose 9, the 1 outside of box is located to hose 9's air outlet. The hot air formed by taking away the heat of the generator 5 by the cold air can pass through the exhaust pipe 8 and the hose 9 on the exhaust hood 7 and is exhausted to the outer side of the box body 1 from the air outlet of the hose 9, and the cooling efficiency of the diesel engine and the generator 5 is greatly improved. The exhaust pipes 8 are spirally and uniformly arranged anticlockwise or clockwise, so that the resistance of hot air exhausted from the exhaust hood 7 can be reduced.
