Embodiment Construction

[0015] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0016] refer to figure 1 As shown in ~3, the condensing fan includes: an impeller body 1, a shaft hole 10 is arranged in the center of the impeller body 1, an air ring 11 is arranged on the outer periphery of the shaft hole 10, and the impeller body 1 is coaxially arranged There is a hub 100, the inner wall of the hub 100 is provided with several ribs 12, and the ribs 12 pass through the inner wall of the hub, and the contact surface of the shaft hole is enlarged, so that the overall deflection of the impeller is reduced.

[0017] Preferably, the outer periphery of the impeller body 1 is provided with a hoop 2, and preferably, the edge of the hoop 2 is provided with a rou...

Abstract

The invention discloses a condensing fan, belongs to the field of permanent-magnetic direct-current micromotors, and is applied to the industry of air conditioner fans of automobiles. The condensing fan comprises an impeller body, wherein the center of the impeller body is provided with a shaft hole, a wind ring is arranged on the periphery by taking the shaft hole as a center, the impeller body is coaxially provided with a hub, and the inner wall of the hub is provided with a plurality of ribs. By changing the hub structure in the fan impeller, the deflection problem of the impeller is essentially solved, and a hoop is additionally arranged on the periphery of the hub, so noises are reduced.

Description

technical field [0001] The invention relates to the field of permanent-magnet direct-current micromotors, and is applied to the automotive air-conditioning fan industry, in particular to a condensing fan. Background technique [0002] With the development of the automobile industry, the requirements for the fan supporting the automobile are getting higher and higher, especially the condensing fan used on the passenger car. The impeller of this type of fan in the prior art has a large outer diameter and a thin thickness. It is prone to deflection problems, and in terms of noise, although it can meet the requirements of level 2 in the automobile industry standard of the People's Republic of China (QC / T708-2004), it is far from the requirements of level 1 and cannot meet the needs of use. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is how to solve the deflection problem that is ea...
