Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1-2, an air intake structure of a super-silent generator set includes a generator set outer casing 100, the middle part of the generator set outer shell is provided with a pair of first partition boards 110 and second partition boards 120 which are longitudinally arranged, a control cabin 111 is formed between one side of the first partition plate, which is far away from the second partition plate, and the generator set outer shell, an air inlet through hole 112 is arranged at one side of the control cabin of the generator set outer shell, a control box 20 is fixed on the generator set outer shell at the upper part in the control cabin, ventilation gaps 210 are left between the front side and the rear side of the control box and the outer shell of the generator set, the top of the first partition plate 110 is provided with an air passing hole 113, the first partition plate is further provided with a third partition plate 130 fixed in the generator set outer shell in parallel towards the side of the second partition plate, and a space is reserved between the lower edge of the third partition plate 130 and the bottom surface inside the generator set outer shell to form a cooling air port 131.

In this embodiment, the two sides of the control box 20 are respectively attached to the first partition plate and the outer housing of the generator set, so that the air entering from the air inlet 112 is discharged from the ventilation gaps 210 at the front and rear sides of the control box to increase the contact area between the control box and the cooling control and increase the ventilation duct, and the air discharged from the ventilation gaps 210 enters the air passing hole 113 at the top of the first partition plate to enter between the first partition plate 110 and the third partition plate 130.

In this embodiment, the top and two sides of the third partition 130 are tightly attached to the generator set housing, so as to ensure that the air entering from the air passing opening is completely discharged from the cooling air opening 131, and further, the air duct is extended to reduce noise without increasing the legal volume and the volume of the housing.
