Description
Technical field
The present invention relates to a kind of digital electricity generating group ventilation cooling unit.
Background technique
Known silencing type digital electricity generating group all adopts the totally enclosed type design, and motor and generator periphery all are wrapped in by shell, and inner surface of outer cover has also been pasted thick sound-absorbing sponge, and the heat of engine interior is difficult to distribute.The generator set of this kind state requires extraordinary radiating condition is arranged otherwise can cause engine overheat, will cause power to descend in the short time.
1, most of in the market silencing type digital electricity generating groups generally all adopt the super sized type silencing apparatus to obtain better noise reduction, motor side cover place in this generator set can be occupied by the silencing apparatus position, although cylinder head and silencing apparatus backplate can constitute an air channel, only can cool off the side of silencing apparatus near cylinder head.In addition because the digital electricity generating group is made every effort to compact structure, silencing apparatus general all with the casing of motor every very near, the motor long-play, the heat that the silencing apparatus surface width of cloth is penetrated can be very fast is transmitted back to the casing side cover, this moment, oil temperature can sharply rise, and machine oil can quicken rotten on high temperature.Motor since lubricated bad can accelerated wear test, even can cause motor to scrap.
2, most in the market digital electricity generating groups all are to utilize the blade driving be contained on the start end flywheel, refill a wind scooper then, and wind scooper is by the cooling air cooled engine cylinder head of trying one's best, and hot air is through silencing apparatus and discharge then.Because the path is longer, behind cooling air process cylinder head, has become very hot, and can only cool off the side of silencing apparatus near cylinder head.This moment, silencing apparatus itself was exactly the thermal source resistance of silencing apparatus in addition to silencing apparatus cooling effect extreme difference, and high-temperature gas may also can cause the circulation phenomenon.Hot air may be stored in the generator set for a long time, also might be absorbed by the carburetor air mouth this moment, causes intake temperature too high, and the intake temperature height can cause not gasification gasification in advance before of gasoline in the Carburetor, cause the motor vapour lock, even can influence the proper functioning of motor.
Summary of the invention
The present invention seeks to: provide a kind of and can eliminate digital electricity generating group internal heat air circulation phenomenon, and the better digital electricity generating group of cooling effect ventilation cooling unit.
Technological scheme of the present invention is: a kind of digital electricity generating group ventilation cooling unit, silencing apparatus, an end of comprise the motor side cover, being located at the motor side cover outside stretch out the bent axle of motor side cover and are installed on the bent axle and the impeller between motor side cover and silencing apparatus, it is characterized in that also being provided with the voluted type wind-guiding device between described motor side cover and the silencing apparatus, being axially arranged with of this voluted type wind-guiding device upper edge bent axle is main into and out of the air port, voluted type wind-guiding device inside has volute shape inner chamber simultaneously, and described impeller is arranged in described volute shape inner chamber.
Further, the present invention also comprises the cylinder head steam outlet pipe, and described voluted type wind-guiding device is provided with the cylinder head exhaust outlet, and described cylinder head steam outlet pipe passes the cylinder head exhaust outlet and links to each other with silencing apparatus.Certainly the same with routine techniques, an end of cylinder head steam outlet pipe is fixed on the engine cylinder head.
Further, the wind-guiding device of voluted type described in the present invention is fastened to form mutually by voluted type wind scooper and voluted type cover plate, and volute shape half chamber on the voluted type wind scooper and the mutual amalgamation in volute shape half chamber on the voluted type cover plate form described complete volute shape inner chamber.
Further again, the cover plate of voluted type described in the present invention is positioned at motor side cover one side, its upper edge bent axle axially have a main air inlet; And described voluted type wind scooper is positioned at silencing apparatus one side, its upper edge bent axle axially have at least two main exhaust outlets.
Preferably, the volute center of the wind scooper of voluted type described in the present invention overlaps with the impeller center, and the beeline at described impeller center to arbitrary main exhaust outlet edge is greater than impeller diameter.
Preferably, the cover plate of voluted type described in the present invention to the motor side cover, and leaves the air-out gap between voluted type cover plate and the motor side cover by bolt; Described silencing apparatus by bolt to the voluted type wind scooper.
Preferably, the exhaust outlet of cylinder head described in the present invention is axially set on the voluted type wind scooper along bent axle, and is positioned at volute shape half chamber one side on this voluted type wind scooper.
Further, the present invention also comprises by being bolted to the silencing apparatus cover plate in the silencing apparatus outside.
Preferably, silencing apparatus described in the present invention is parallel with impeller, and all vertical with bent axle.
Preferably, main exhaust outlet described in the present invention is evenly spaced apart in the form of a ring.
The mount mode of silencing apparatus described in the present invention, impeller and bent axle, and the Placement of cylinder head steam outlet pipe and silencing apparatus is prior art, the present invention is no longer stating to this more.
Concrete working principle of the present invention is explained as follows: this digital electricity generating group ventilation cooling unit provided by the invention is the part of digital electricity generating group, when the digital electricity generating group is worked, impeller is rotated by crank-driven, impels the cooling of dispelling the heat of air ventilation logarithmic code generator set.The flow direction of gas is mainly divided following three kinds of situations: 1, portion gas sucks from the engine start end, passes through generator unit stator, cylinder head, cylinder head steam outlet pipe, discharges from silencing apparatus at last; 2, portion gas sucks from motor top or sucks from the engine start end, through engine crankcase, impeller, finally quickens to discharge from silencing apparatus by voluted type wind-guiding device pressurization back; 3, (the Carburetor inlet of motor) sucks or sucks from the engine start end from motor cavity bottom, through engine crankcase, impeller, finally quickens to discharge from silencing apparatus by voluted type wind-guiding device pressurization back.
