[0035] 3. Generator set Specific embodiments

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the scope of protection of the present utility model.

[0037] The existing exhaust air mechanism provided inside a generator set adopts the form of opening an exhaust air port on the outer shell of the generator set, and drives the heat inside the generator set to be discharged by wind power. However, for the generator set, this design will generate relatively large noise during the exhaust air process, and relatively large air currents will be generated at the exhaust air port, resulting in dust being raised.

[0038] To solve the above technical problems, in at least one embodiment, an exhaust air device for a generator set is provided, including: an air guiding mechanism provided inside the generator set 3; wherein the air guiding mechanism includes: a primary air guiding component 1 and a secondary air guiding component 2; and the primary air guiding component 1 is arranged at the air guiding outlet of the secondary air guiding component 2.

[0039] By providing the primary air guiding component and the secondary air guiding component, the secondary air guiding component arranged in a curved shape is used for exhaust air, reducing the exhaust air speed, and arranging the primary air guiding component at the exhaust air port of the secondary air guiding component, further reducing the exhaust air speed while not affecting exhaust air and heat dissipation, thereby reducing noise.

[0040] In some embodiments, a partition board 20 is provided inside the generator set 1, and an air guiding opening 22 is opened in the center of the partition board 20. The partition board 20 is arranged on one side of the generator compartment, and the heat dissipated in the generator compartment is discharged through the air guiding opening 22 by the air source provided in the generator compartment.

[0041] In some embodiments, a number of secondary air guiding members 21 are vertically fixed on one side of the partition 20 away from the generator compartment. The width of each secondary air guiding member 21 is the same as the width of the air guiding opening 22. At this time, the gap formed between every two adjacent secondary air guiding members 21 is the secondary air guiding channel. The air flow passing through the air guiding opening 22 is discharged through the secondary air guiding channel. By bending the design of each secondary air guiding member 21, compared with the prior art that uses a straight channel for exhausting air, the wind speed is reduced and the wind noise is decreased.

[0042] In some embodiments, a number of primary air guiding members 10 are fixed on the inner wall of the generator set. Each primary air guiding member 10 is preferably a square plate. One side of each primary air guiding member 10 is fixed to the inner wall of the generator set, and the other side faces each secondary air guiding member 21. And each primary air guiding member 10 is arranged longitudinally. The gap formed between every two adjacent primary air guiding members 10 is the primary air guiding channel. According to the above description, after the air flow is discharged through the secondary air guiding channel, it will impact on the side surface of each primary air guiding member 10. The primary air guiding member 10 decelerates the air flow, thereby reducing the noise. Finally, the air flow passes through the primary air guiding channel and is discharged from the exhaust holes opened on the upper end surface of the generator set. To prevent rainwater from flowing back, a cover plate can be fixed on the exhaust holes.

[0043] In some embodiments, to further reduce the wind noise, sound-absorbing sponges can be added on the surfaces of the primary air guiding member 10 and the secondary air guiding member 21, and a thin plate with mesh holes is installed on the surface of the sound-absorbing sponge to prevent it from being blown off by the air flow.

[0044] In summary, by setting the primary air guiding assembly and the secondary air guiding assembly, the secondary air guiding assembly with a bent setting is used for exhausting air, reducing the wind speed of the exhausted air. And the primary air guiding assembly is arranged at the air outlet of the secondary air guiding assembly, further reducing the wind speed of the exhausted air without affecting the exhaust heat dissipation, thereby reducing the noise.
