Between formed motor inlet chamber, rack air inlet connection motor inlet chamber；Right plate upper middle position opens up motor air inlet,
Enclosure interior arranges wind-guiding dividing plate along its length, forms separate chamber between wind-guiding dividing plate and housing, only with this on right plate
Vertical chamber opposite position is provided with power air outlet；On housing air filter air inlet, housing are provided with corresponding to engine one end sidepiece
It is internally corresponding to be provided with air filter inlet chamber at air filter air inlet, compartment spacers is provided with inside air filter inlet chamber.
As a further improvement on the present invention, the chassis edge is provided with gas port.
As a further improvement on the present invention, the air filter air inlet is arranged to air-inlet grille.
The technical effects of the invention are that：Product conception of the present invention is ingenious, rationally distributed, by for existing generating set
The problem of existing noise is big at work, cooling effect is poor carries out specific aim improvement so that into generating set inside cavity
Air by flowing to rational water conservancy diversion, realize the noise reduction for generating set inside cavity and cooling, reach preferable cooling
Noise reduction.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
The embodiment of the present invention is further described below in conjunction with the accompanying drawings.
In Fig. 1, including housing 1, rack air inlet 2, air filter air inlet 3, motor inlet chamber 4, motor air inlet 5, power
Air outlet 6, compartment spacers 7, air filter inlet chamber 8, cabin side plate 9, right plate 10, wind-guiding dividing plate 11, chassis 12, wind deflector 13
Deng.
As shown in figure 1, the present invention is a kind of air inlet noise-reducing structure of mute generator group, including chassis 12 and fastening connect
The housing 1 being connected on chassis 12, housing 1 are provided with rack air inlet 2 corresponding to generator one end sidepiece, and the sealing of the right-hand member of housing 1 is set
Right plate 10 is put, cabin side plate 9 is set in the inner side of right plate 10, the edge of cabin side plate 9 is bent towards the side of right plate 10, cabin
The kink of side plate 9 is posted by right plate 10, and wind deflector 13, wind deflector 13 and cabin side are additionally provided with cabin side plate 9
Motor inlet chamber 4 is formed between the kink of plate 9, rack air inlet 2 connects motor inlet chamber 4；The top interposition of right plate 10
Put and open up motor air inlet 5, arrange wind-guiding dividing plate 11 inside housing 1 along its length, formed between wind-guiding dividing plate 11 and housing 1
Separate chamber, power air outlet 6 is provided with the separate chamber opposite position on right plate 10；Correspond to engine on housing 1
One end sidepiece is provided with air filter air inlet 3, and housing 1 is internally corresponding to be provided with air filter inlet chamber 8, air filter air inlet at air filter air inlet 3
The inside of chamber 8 is provided with compartment spacers 7.Air filter air inlet 3 is arranged at the lower position of air filter inlet chamber 8, and air is entered by air filter air inlet 3
After entering air filter inlet chamber 8, to the upper flow of air filter inlet chamber 8, and via after the top plate reflexed of air filter inlet chamber 8 towards compartment spacers
7 sides are flowed, and after air flows through compartment spacers 7, are bypassed from the top of compartment spacers 7, towards the air cleaner position of engine
Flow away.
The edge of chassis 12 is provided with gas port, and gas port can strengthen air inlet/outlet effect.
Air filter air inlet 9 is arranged to air-inlet grille, and air-inlet grille avoids the sound caused by air directly flows.
The course of work of the present invention is as follows：At work, the air outside generating set is via air filter air inlet 3, rack
Gas port on air inlet 2, motor air inlet 5 and chassis 12 enters generating set inside cavity.Enter via air filter air inlet 3 and send out
