Abstract

The invention relates to a fan wheel, and belongs to the technical field of fans. The fan wheel comprises a hub and a first blade set evenly distributed on the hub in the circumferential direction, the end, away from the hub, of the first blade set is fixedly connected with a hot wheel reinforcing ring, the hot wheel reinforcing ring is fixedly connected with a second blade set, the second blade set comprises a plurality of blades with unequal lengths, and the blades are fixedly connected with the hot wheel reinforcing ring. Each unequal-length blade is inserted between every two adjacent blades of the first blade set, at least one protruding part is arranged on the hot wheel reinforcing ring, and the orientation of the protruding parts is consistent with the rotating direction of the fan wheel. On the premise that the blade strength is met, the problem that the number of the blades is small is solved, the air supply effect is improved, noise generated by fan operation is reduced, the problem that the fan blades are prone to being affected by air resistance to shake or even deform is solved, and the better ventilation effect is provided in the fan blade operation process.

Description

technical field [0001] The invention relates to a fan wheel, which belongs to the technical field of fans. Background technique [0002] The heat dissipation performance of the fan is mainly related to the blades of the fan. The more blades, the better the air supply effect. However, in the conventional design, the number of blades of the fan is very small, which leads to the poor air supply effect. At the same time, the energy concentration at a single frequency when the conventional blades are running, resulting in noise when the fan is running, and the blades of the fan are also easily affected by air resistance. Shaking or even deformation, there is a problem that the strength of the blade cannot meet the needs of use. [0003] The information disclosed in this Background section is only for enhancement of understanding of the general background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior...
