Problems solved by technology

Through the opening of the shroud, the wind exported by the fan is concentrated in a specific direction, but the structure of the existing shroud is relatively simple, the air outlet is single, and the direction of the wind is fixed. Mutual interference between adjacent fan blades makes the efficiency of the fan lower and the noise higher

Abstract

The invention discloses a multi-group small fan, and relates to the technical field of fans. The multi-group small fan comprises a base, small fans and a wind gathering cover; three small fans are arranged in the base; the three small fans are separated by partition plates; the transverse interference of wind power is effectively avoided, and meanwhile, the tops of the three fans are guided by a wind gathering cover; a conical wind gathering groove is formed in the surface of the wind gathering cover; fan blades are arranged in the wind gathering groove; wind power is pressurized and guided into a wind guide groove through the fan blades in the flow guide process; high-pressure wind in the wind guide groove is exhausted from the three wind outlets, so that the wind outlet amount and the wind pressure are effectively increased; and meanwhile, a first-stage buffer mechanism is arranged between the two small fans, a second-stage buffer mechanism is arranged in the first-stage buffer mechanism, and therefore, in the working process, the first-stage buffer mechanism and the second-stage buffer mechanism are used for conducting multiple times of buffer damping on vibration force, so that impact force is counteracted continuously, vibration of the fans is effectively reduced, and the noise of the fans is low.

Description

technical field [0001] The invention relates to the technical field of fans, in particular to multiple groups of small fans. Background technique [0002] Modern fans have higher and higher requirements for air volume and wind pressure. When the air volume and wind pressure required by the product are large, if a single fan cannot meet the requirements, two or more fans should be selected for joint operation. When multiple fans are used During joint operation, a shroud is often installed outside multiple fans. Through the opening of the shroud, the wind exported by the fan is concentrated in a specific direction, but the structure of the existing shroud is relatively simple, the air outlet is single, and the direction of the wind is fixed. Mutual interference between adjacent fan blades makes the efficiency of the fan lower and the noise higher. Contents of the invention [0003] Aiming at the problems existing in the prior art, the object of the present invention is to ...
