Below with reference to the accompanying drawings and in conjunction with the embodiments, describe the present invention in detail.
The invention provides 4 kinds of embodiments:
1, embodiment mono-:
As shown in Figure 1 to Figure 3, the generating set 1 of this patent is mainly made up of engine, generator and casing 2 etc.
The generator of the present embodiment is multiple permanent magnet generator, is connected with engine crankshaft output, under the driving of engine, exports medium frequency alternating current. Be provided with inverter in engine front portion, the medium frequency alternating current that inverter is used for that multiple permanent magnet generator is exported converts the industrial-frequency alternating current of voltage stabilization to. But application of the present invention is not subject to the restriction of generator kind, obviously the present invention also can be used for the generating set of other types, and for example various have brush or brushless electric excitation synchronous generator group, or various dc generator.
As shown in Figure 1 to Figure 3, engine, generator and inverter are housed inside in casing 2, on casing 2, be provided with the air inlet 3 communicating with ambient atmosphere, on engine, be provided with fan, under this fan effect, outside air is inhaled into casing 2 inside from air inlet 3, the air that enters casing 2 carries out cooling to engine, generator and inverter etc., also for engine combustion acting provides fresh air.
Outside air is to enter casing 2 by the flow channels 303 of air inlet 3, this flow channels 303 is formed between outside opening 301 and inside opening 302, the outside opening 301 of air inlet 3 is arranged on the outside of casing 2, and the inside opening 302 of air inlet 3 is arranged on the inside of casing 2. The flow channels 303 that outside air first enters air inlet 3 from outside opening 301, then flows to inside opening 302 along flow channels 303, finally flows out, enters casing 2 inside from inside opening 302.
As shown in Figure 1 to Figure 3, this patent is provided with airscoop shroud 4 at air inlet 3 places, and airscoop shroud 4 is positioned at the outside of casing 2, belongs to external airscoop shroud, and at least part of being formed on airscoop shroud 4 of flow channels 303 of air inlet 3 forms inlet channel 304.
At casing 2 or airscoop shroud 4, outstanding position all can be set, the outstanding position arranging on casing 2 is hereinafter to be referred as outstanding position A, and the outstanding position arranging at airscoop shroud 4 is hereinafter to be referred as outstanding position B; Concrete, as shown in Figure 1, on casing 2, be provided with outstanding position 201, on airscoop shroud 4, be provided with outstanding position 401, and interlaced arrangement, to change sound direction of wave travel, outstanding position 201 is to extend and form from casing 2 to airscoop shroud 4, extending end is positioned at the flow channels 303 of air inlet 3 and the connectivity part of inlet channel 304, and outstanding position 401 is to extend and form from airscoop shroud 4 to casing 2, and elongated end is arranged in inlet channel 304.
The difference of the present embodiment Fig. 2 and Fig. 1 is, the casing air inlet 3 of Fig. 2 has increased a flow channels 303 and inlet channel 304, accordingly, on casing 2, increase outstanding position 202, on airscoop shroud 4, also increase outstanding position 402, the same with outstanding position 201, outstanding position 202 is also to extend and form from casing 2 to airscoop shroud 4, extending end is positioned at the flow channels 303 of air inlet 3 and the connectivity part of inlet channel 304, the same with outstanding position 401, outstanding position 402 is also to extend and form from airscoop shroud 4 to casing 2, the inlet channel 304 that extending end is arranged in, increase total area of passage that the flow channels 303 of air inlet 3 and the quantity of inlet channel 304 are equivalent to increase casing air inlet, under the same conditions, can increase the air mass flow that enters casing 2, improve the heat dispersion of generating set, increase the power output of generating set under hot environment. therefore, can need to increase the flow channels 303 of air inlet 3 and the quantity of inlet channel 304 according to heat radiation, the flow channels 303 of air inlet 3 and inlet channel 304 are more than two conventionally.
The airscoop shroud 4 of the present embodiment is arranged on the outside of casing 2, belongs to external airscoop shroud, and airscoop shroud 4 can link together by elastic constructions such as buckles with casing 2, also can link together by securing members such as screws.
Airscoop shroud 4 can be made up of plastic material, and such as PP, PA or ABS etc., also can be made up of soft materials such as rubber, such as NBR, PVC or polyurethane etc.
In the time that generating set internal noise is propagated to the external world along the flow channels 303 of casing air inlet 3 and inlet channel 304, can be subject to being arranged in the outstanding position A of inlet channel 304 and stopping of outstanding position B, two kinds of outstanding position A and the B of interlaced arrangement force sound wave repeatedly to change direction, and occur repeatedly expand and shrink, in inlet channel 304 through multiple reflections and interfere after, noise is attenuated rapidly, only have little noise can leak into casing outside, thereby the work noise of generating set is reduced greatly.
As shown in Figure 3, in order further to reduce noise, this patent is provided with sound-absorbing material 5 between casing 2 and airscoop shroud 4, and its position is near airscoop shroud 4 one sides.
