Abstract

The invention discloses a low-noise fan for a diesel generator set. The low-noise fan is provided with a fan hub, at least two fan blades are uniformly distributed in the circumferential direction ofthe fan hub, the edges of the outer ends of the fan blades are jointly connected with an air guide groove of an integrated structure with the fan blades, and the outer contour lines of the fan bladesare in smooth radians. According to the low-noise fan disclosed by the invention, the air guide groove is additionally arranged on the fan, the wind volume is increased, the cooling effect is good, the power loss of an engine is reduced, the normal working temperature of circulating water is ensured, and meanwhile the noise of the fan during working is small.

Description

technical field [0001] The invention belongs to the technical field of power generation equipment, in particular to a low-noise fan used in a diesel generator set. Background technique [0002] Diesel generator set is a kind of power equipment that uses diesel engine as the prime mover to drive synchronous generator to generate electricity. Although diesel engine has the advantages of good thermal efficiency and economy. In the prior art, the impeller of the fan of the diesel generator set is only composed of the fan hub and blades, and the air volume during operation is reduced, so the cooling effect is poor, the reliability is poor, and the operating noise is large. Contents of the invention [0003] In order to overcome the problems existing in the prior art, the present invention provides a low-noise fan used in diesel generator sets. Air guide grooves are added on the fan, so that the air volume becomes larger, the cooling effect is good, and the power loss of the eng...
