Therefore, the technical solution adopted in the present invention is：A kind of generating set of efficient dual cooling air flues, including unit
Shell, the engine generator being arranged in unit casing, the engine generator include having cooling but cylinder head and noise elimination
The electric motor cooling duct that engine cool air channel that the cooling wind of device passes through and cooling wind with cooling but motor pass through, it is special
Levy and be：
The air inlet in the engine cool air channel is arranged in starter pulling plate, and air outlet is arranged on silencer outlet glue
Put, the cylinder head and silencer are arranged on the airtight passage formed between the air inlet in engine cool air channel and air outlet
It is interior；The air inlet of the electric motor cooling duct is separately positioned on the top, side and bottom of engine case lid, and air outlet is arranged on
On electric motor end cap, cooling fan and motor are placed in the airtight passage formed between the air inlet of electric motor cooling duct and air outlet
It is interior；The air inlet, the air outlet in engine cool air channel, electricity with engine cool air channel are respectively arranged with the unit casing
The air inlet of machine cooling air channel, the corresponding air-inlet grille of the air outlet position of electric motor cooling duct；
The cooling fan includes plate-like body and blade, and both are integrally formed, and is provided with the plate-like body and some is in
The mistake air holes of circumference uniform distribution, blade is arranged on the front of plate-like body and corresponded with crossing air holes, the cross section of the blade
For arch, gradually decrease up to and be connected as a single entity with crossing the edge of air holes along the air intake direction dome height of cooling fan, so that shape
Into the arc cover structure with air intake vent, and arc-shaped cover covers corresponding air holes of crossing completely, when cooling fan is rotated, wind from
Air intake vent enters in blade, and arcuately cover is turned over after certain angle again by crossing air holes discharge.
As the preferred of such scheme, the starter, cooling fan and motor are arranged on the next of engine generator
Layer, air filter, cylinder head and silencer are arranged on the last layer of engine generator, and the engine cool air inlet of air duct is with going out
Airtight passage between air port is surrounded by starter wind scooper, cylinder head wind scooper, muffler outer hood and silencer outlet gum cover, institute
The airtight passage stated between electric motor cooling duct air inlet and air outlet is surrounded by engine case lid and electric motor end cap.Optimize structure
Arrangement, makes overall structure more compact and reasonable, reduces area occupied.
The medial extremity opposed outer ends of the blade arched cross-section, are tilted rearward on air intake direction；The air intake vent
Top opposing root, tilted backwards on air intake direction.Further to optimize air intake route, make the wind entered in arc-shaped cover more
Plus it is smooth, it is more preferable to the cooling effect of motor.
Beneficial effects of the present invention：For cooling down the engine cool air channel of cylinder head and silencer and for cooling down motor
Electric motor cooling duct is provided separately, and two-way cooling air channel is each independent, and the cooling wind in engine cool air channel is in starter
Fan is sucked, and the cooling wind of electric motor cooling duct is sucked by cooling fan, it is ensured that the sufficient intake in two air channels, air intake
It is smooth, and good cooling results；Because two cooling air channels are independently arranged, air channel structure and air channel arrangement are simplified, zero is reduced
Number of packages amount, reduces manufacturing cost；The blade of motor cooling fan use arc cover structure, coordinate engine case tops,
Electric motor cooling duct air inlet at side and the three of bottom setting, so as to increase the digging air quantity of cooling fan, further improves electricity
The cooling effect of machine.
