Description

Technical Field

[0001] The invention relates to the technical field of blower equipment, and in particular to a blower silencing device. Background Art

[0002] The magnetic levitation centrifugal blower is a high-speed and efficient fan-type equipment, which integrates magnetic levitation bearings, magnetic levitation bearing controllers, high-speed permanent magnet synchronous motors, high-speed motor inverters, three-dimensional flow impellers and intelligent control systems. Since the fan needs to be cooled during operation, the heat generated by the internal operation of the fan is discharged in time to ensure the smooth operation of the fan. After the hot air is discharged, a certain noise will be generated to affect the surrounding working environment. On the other hand, when the fan is vented, a certain noise will also be generated. In order to reduce the impact of the noise generated by the operation of the fan on the surrounding working environment, it is necessary to perform noise reduction on the exhaust end. When the noise reduction is performed, it is necessary to consider the rationality and reliability of the layout of the venting exhaust and cooling exhaust in the chassis. Therefore, a fan silencing device is needed. Summary of the invention

The venting silent cabin and the heat exhaust silent cabin are separately provided, thereby preventing the wind pressure at the venting outlet from flowing back into the cooling outlet of the fan during shutdown and venting, thereby preventing damage to the heat dissipation impeller.

[0009] By arranging multiple sets of vent silent panels in the vent silent cabin, the noise generated by the vent valve during the venting process can be effectively filtered, and the vent outlet and the air inlet connected to the vent valve end are arranged diagonally in the vent silent cabin, which can maximize the filtering area of ​​the vent silent panel and thus improve the silent treatment effect.

[0010] By arranging multiple sets of heat exhaust silent panels in the heat exhaust silent cabin, the hot air discharged from the fan cooling outlet can be noise-reduced. At the same time, the heat exhaust outlet and the bottom of the heat exhaust silent cabin are connected to the air inlet end at the fan cooling outlet and are arranged diagonally in the heat exhaust silent cabin, which can increase the filtering effect of the multiple sets of heat exhaust silent panels.

[0011] In one embodiment of the present invention, a venting through hole is opened on the side wall of the air outlet duct, a venting pipeline is connected between the venting through hole and the venting silent cabin, and the venting valve is arranged on the venting pipeline.

[0012] To implement the above technical solution, by setting the venting through hole, the venting valve can be used to vent the fan during the venting process, thereby improving the stability and reliability of the venting process.

[0014] To implement the above technical solution, by arranging the venting and silent panels equally in the venting and silent cabin, the filtering effect of the venting and silent panels can be ensured, and the stability of use of the venting and silent panels can be improved. By setting the venting and silent pipe through the venting and silent panel, the stability and smoothness of the venting airflow in the venting and silent pipe can be improved, thereby achieving a better silent effect.

[0015] In one embodiment of the present invention, the heat exhaust silent plates are equally arranged in the heat exhaust silent cabin, a heat exhaust silent pipe is provided in the heat exhaust silent cabin, the heat exhaust silent pipe penetrates the heat exhaust silent plates, and a silent through hole is provided on the heat exhaust silent pipe.

[0017] In one embodiment of the present invention, a vent filter is provided at the vent outlet, the vent outlet is arranged as a fan-shaped outlet, and the opening end is arranged away from the air outlet end of the fan.

[0018] To implement the above technical solution, by setting a vent filter, external debris can be prevented from entering the vent outlet. The vent outlet is set as a fan-shaped outlet with the open end facing away from the fan outlet end, which can ensure the airflow stability of the fan-shaped outlet during venting.

[0019] As described above, a fan silencing device of the present invention has the following beneficial effects: by setting a silencing component, the airflow during venting and heat exhaust is silenced to reduce the impact on the surrounding working environment, and the venting silent cabin and the heat exhaust silent cabin are set separately, which can prevent the wind pressure at the venting outlet from flowing back into the cooling outlet of the fan during shutdown venting and causing damage to the heat dissipation impeller, and by providing multiple sets of venting silent panels in the venting silent cabin, the noise generated by the venting valve during venting can be effectively filtered, and the venting outlet and the air inlet connected to the venting valve end are arranged diagonally in the venting silent cabin, which can maximize the filtering area of ​​the venting silent panel, thereby improving the silencing effect.
