Description

Technical Field

[0001] The utility model relates to the technical field of centrifugal fans, in particular to a foaming noise-resistant fan. Background Art

[0002] For the cabinet fans currently on the market and in circulation, the chassis is generally made in the form of a single board with a thickness of 1.00 mm - 1.50 mm. After large-area components such as the upper cover, lower plate, and side doors of the chassis are bent and formed, the smaller ones are 0.5 m by 0.6 m, and the larger ones are 1.55 m by 2.06 m. When the fan operates, the flow, impact, and friction of the air will cause it to vibrate or shake, generating a large amount of noise. To reduce the noise, usually, stiffeners are added or sound-absorbing cotton is lined on the inner wall of the chassis to reduce the noise.

[0003] However, in the above-mentioned prior art, the methods of adding stiffeners or lining sound-absorbing cotton on the inner wall of the chassis easily cause the deformation of the appearance of the box body, which is not beautiful, and the effect of suppressing vibration conduction and noise reduction is not good. Content of the Utility Model

[0004] The purpose of the utility model is to provide a foaming noise-resistant fan, aiming to solve the technical problems in the prior art that, by adding stiffeners or lining sound-absorbing cotton on the inner wall of the chassis, it is easy to cause the deformation of the appearance of the box body, which is not beautiful, and the effect of suppressing vibration conduction and noise reduction is not good.

[0005] To achieve the above purpose, a foaming noise-resistant fan adopted by the utility model includes two side plates, two front vertical beams, two front horizontal beams, a main chassis front plate, a sub-chassis front plate, a front middle beam, a connecting component, an upper sealing component, a lower sealing component, and a partition. The two front vertical beams are respectively connected to the two side plates. The two front horizontal beams are symmetrically arranged between the two front vertical beams. The two ends of each front horizontal beam are respectively connected to the two front vertical beams. The two ends of the front middle beam are respectively connected to the two front horizontal beams. The main chassis front plate is arranged on one side of the front middle beam. The sub-chassis front plate is arranged on the side of the front middle beam away from the main chassis front plate. The partition is arranged between the two side plates and is connected to the front middle beam. The connecting component is arranged between the two side plates. The upper sealing component is arranged at the upper end of the partition. The lower sealing component is arranged at the lower end of the partition.

[0006] Among them, the connecting component includes two rear vertical beams, two rear horizontal beams, a rear middle beam, and a sub-chassis rear plate. The two rear vertical beams are respectively connected to the two side plates. The two rear horizontal beams are symmetrically arranged between the two rear vertical beams. The two ends of each rear horizontal beam are respectively connected to the two rear vertical beams. The two ends of the rear middle beam are respectively connected to the two rear horizontal beams. The sub-chassis rear plate is arranged on one side of the rear middle beam.

[0007] Among them, the upper sealing assembly includes an upper cover plate of the main chassis and an upper cover plate of the auxiliary chassis. The upper cover plate of the main chassis is arranged on one side of the partition board, and the upper cover plate of the auxiliary chassis is arranged on the side of the partition board away from the upper cover plate of the main chassis.

[0008] Among them, the lower sealing assembly includes a lower disk of the main chassis and a lower disk of the auxiliary chassis. The lower disk of the main chassis is arranged on one side of the partition board, and the lower disk of the auxiliary chassis is arranged on the side of the partition board away from the lower disk of the main chassis.

[0009] A foaming noise-resistant fan of the present utility model, when in use, divides the area between the two side plates into two parts, namely a main chassis and an auxiliary chassis, by means of the partition board. The main chassis is used to set the main flow field, and the auxiliary chassis is used to set the transmission device. The front vertical beam, the front cross beam and the front middle beam are all made of metal profiles, and foaming filling is arranged inside the metal profiles. The side plates, the front plate of the main chassis, the front plate of the auxiliary chassis and the partition board are all made of metal outer skins, and foaming filling is arranged inside the metal outer skins, thereby completely eliminating the resonant sound of the hollow cavity during the operation of the fan. By means of foaming filling, the overall strength of the fan chassis is higher, avoiding the phenomena of jitter and wave surging of the metal plate of the box body during the operation of the fan. In this way, it can effectively solve the problems in the prior art that by increasing the reinforcing ribs or lining the inner wall of the box with sound-absorbing cotton, it is easy to cause the deformation of the appearance of the box body, which is not beautiful, and the effect of suppressing the conduction of vibration and noise reduction is not good.
