Close, cabin is divided into two parts by the partition board with rubber strip and radiator on hatch door, unclosed on the inside of engine, air from this not
It is run out of at closing, air can only enter inlet channel by air-inlet grille, and layout can ensure to pass through air cleaner in this way
Into the air themperature of engine chamber, consistent with environment temperature (intake air temperature is no more than environment at general engine body
10 degree of temperature), while the air containing a large amount of airborne dusts also being avoided to enter, and air cleaner service life is caused to decline.
In the cooling system of above-mentioned engine nacelle, the exhaust structure includes the heat dissipation being located on the inside of engine
Channel and the exhaust pipe on engine, the exhaust pipe extend from cabin on the outside of lateral cabin, and the exhaust pipe
Exhaust outlet is towards the side of cabin.After air burns within the engine, by exhaust gas processing device, it is discharged from exhaust pipe, exhaust
Pipe moves towards side from the inside, can enter cabin in bottom of frame to avoid the high-temp waste gas of discharge in this way, also avoid simultaneously
Airborne dust caused by the wind that cabin ejects enters exhaust pipe and exhaust gas processing device, and then leads to engine failure.
In the cooling system of above-mentioned engine nacelle, the fan is hydraulic fan.By changing liquid in fan
The flow direction of pressure oil realizes the reverse rotation of fan, blows out the dust in radiator, to achieve the purpose that clean radiator, improves and dissipates
The service life of hot device.
In the cooling system of above-mentioned engine nacelle, the hatch door be gull wing type hatch door, and the hatch door with
The line for the axis that the line and engine, fan, radiator of each hinge joint of cabin are arranged is parallel.In order in cabin
It safeguards.
Compared with prior art, the advantages of cooling system of this engine nacelle, is：Each component layouts are closed in cabin
Reason can ensure consistent with environment temperature to enable the engine to reach thermal balance shape into the air themperature of engine chamber
State, while hydraulic oil being allowed to be maintained at suitable temperature；And exhaust pipe is oriented inside outward, avoids enging cabin row
Airborne dust, which enters exhaust pipe and exhaust gas processing device, caused by wind out leads to engine failure.
