Therefore, the technical solution adopted in the present invention is:A kind of mute power generator group air channel, includes the cabinet of closing, if Put air filter, carburetor, the power box with cylinder head, motor, silencer and fan in cabinet, it is characterised in that:Institute State and first, second dividing plate is provided with cabinet, cabinet is divided into separate first, second, third successively from right to left Cabinet, the air filter and carburetor are arranged in the first cabinet, and power box and motor are arranged in the second cabinet, silencer It is arranged on fan in the 3rd cabinet, the first air inlet is provided with the right side wall of cabinet, it is just right to be provided with the first cabinet The baffle plate of first air inlet, is provided with the second air inlet at the top of the second cabinet, and air outlet is provided with the left side wall of cabinet;
Ambient atmosphere enters the first cabinet from the first air inlet, and a portion is flowed up along baffle plate, crosses baffle plate Enter power box by power wind scooper, and the closed channel through cylinder head and the formation of cylinder head outer cover dissipates for cylinder head outer wall After heat, then by power air channel enter the 3rd cabinet, finally from air outlet discharge, constitute the first cooling air channel;
Ambient atmosphere enters the first cabinet from the first air inlet, and a portion flows downward along baffle plate, crosses baffle plate Burnt successively through air filter, carburetor into cylinder head afterwards, the hot gas produced by cylinder head burning is accessed through admission line and eliminated the noise Device is discharged into the 3rd cabinet again, is finally discharged from air outlet, constitutes the second cooling air channel;
Ambient atmosphere enters from the second air inlet, after being motor radiating through motor air channel, then introduces the 3rd cabinet by fan, Until from air outlet discharge, constituting the 3rd cooling air channel;
Hot gas in second cabinet, introduces the 3rd cabinet, and from air outlet discharge, constitute the 4th cooling air channel through fan.
As the preferred of such scheme, the power duct shield is fastened by two half shells and formed outside admission line;Make Power air channel is simultaneously admission line radiating, it is to avoid the heat of admission line enters in the second cabinet, causes heat in the second cabinet It is excessive, while making overall structure more compact.
The motor and power box the left and right arrangement in the second cabinet, cylinder head are arranged on the bottom of power box, move Power air channel is located at the underface of motor.Preferred arrangement, further improves overall compactedness.
Beneficial effects of the present invention:According to the work characteristics of generating set, four cooling air channels are set in generating set, First cooling air channel radiates for power box, the burning radiating of the second cooling air channel cylinder head, and the 3rd cooling air channel is motor radiating, 4th cooling air channel radiates for the second cabinet inside, it is achieved thereby that each large-scale heat generating components is all dropped using air cooling way Ventilation and heat inside temperature, general warranty unit, has reached the optimal noise reduction of generating set, it is ensured that generating set work The reliability of work.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
Embodiment
Below by embodiment and with reference to accompanying drawing, the invention will be further described:
As shown in figure 1, a kind of mute power generator group air channel, mainly by the cabinet 1 closed, is arranged on air filter in cabinet 1 2nd, carburetor 3, the power box 4 with cylinder head 5, motor 6, silencer 7, fan 10 etc. are constituted.
First, second dividing plate 8,9 is provided with cabinet 1, cabinet 1 is divided into separate successively from right to left First, second, third cabinet 1a, 1b, 1c.Air filter 2 and carburetor 3 are arranged in the first cabinet 1a, power box 4 and motor 6 It is arranged in the second cabinet 1b, silencer 7 and fan 10 are arranged in the 3rd cabinet 1c.Is provided with the right side wall of cabinet 1 One air inlet 1d, is provided with the baffle plate 11 just to the first air inlet 1d in the first cabinet 1a, is set at the top of the second cabinet 1b The second air inlet 1e is equipped with, air outlet 1f is provided with the left side wall of cabinet 1.It is provided with second partition 9 just to fan 10 Air-vent.
Cylinder head 5 is the part of power box 4, and power box 4 is equipped with power wind scooper 12, power wind scooper 12 Gas in first cabinet 1a is introduced in power box 4, is that power box 4 radiates.Motor 6, will equipped with motor air channel 14 Second air inlet 1e gas is introduced in motor 6, is that motor 6 radiates.
Four cooling air channels are provided with mute power generator group altogether, (the gas flow of each cooling air channel is introduced one by one below As shown by arrows in FIG.):
