Technical Field

The invention relates to the technical field of fan component manufacturing, in particular to a current collector with an air outlet flow guide structure.

Background

The working principle of the fan is that the impeller moves relatively in the fan shell to compress and convey gas, the impeller pressurizes and accelerates the gas flow, and electric energy is converted into kinetic energy and potential energy of the gas. In the prior art, the work efficiency and the air inlet efficiency of the fan impeller are relatively large, and the problem which always troubles the centrifugal fan is that the impeller is more air inlet by the air inlet part, and less air inlet is far away from the air inlet part, so that the airflow is not uniform, the turbulent flow is easy to form, the air outlet efficiency of the fan is reduced, and the noise of the fan is increased.

Disclosure of Invention

Aiming at the defects of the prior art, the invention solves the technical problem of how to improve the air inlet distribution of the fan impeller, reduce the turbulent flow, reduce the noise and simultaneously improve the air outlet efficiency of the fan.

In order to solve the technical problem, the invention adopts the technical scheme that the current collector with the air outlet flow guide structure comprises a current collector body and a flow guide cover, wherein the flow guide cover is a shell, a plurality of uniformly distributed connecting ribs are arranged on the lower edge of the shell and fixedly connected with the inner wall of an air outlet port of the current collector body, and the purpose of uniformly guiding air flow to an inner cavity of an impeller is realized after the air flow entering from the outside is guided along the shell of the flow guide cover.

The air guide sleeve is a nearly hemispherical rotary shell.

In order to reduce the influence on the intake airflow, as a modification of the present invention, the number of the connecting ribs is 4.

The connecting ribs and the inner wall of the air outlet port of the collector body are fixedly connected in a welding or integral die forming mode.

The connecting mode of the connecting ribs and the air guide sleeve is welding or integral die forming.

By adopting the technical scheme of the invention, the air inlet distribution of the inner cavity of the impeller is effectively improved, the turbulence is reduced, the air outlet efficiency of the fan is improved and the noise is reduced.

Detailed Description

The following further describes the embodiments of the present invention with reference to the drawings, but the present invention is not limited thereto.

Fig. 1 and 2 show a current collector with a gas outlet flow guide structure, which comprises a current collector body 1 and a flow guide cover 11, wherein the flow guide cover 11 is a shell, a plurality of uniformly distributed connecting ribs 12 are arranged on the lower edge of the shell and fixedly connected with the inner wall of a gas outlet port of the current collector body 1, and the purpose of uniformly guiding the gas flow to an inner cavity of an impeller is achieved after the external air flow is guided along the shell of the flow guide cover 11.

The air guide sleeve 11 is a nearly hemispherical rotary shell.

In order to reduce the influence on the intake airflow, as a modification of the present invention, the number of the connecting ribs 12 is 4.

The connecting ribs 12 are fixedly connected with the inner wall of the air outlet port of the collector body 1 by welding or integral die forming.

The connection mode of the connecting rib 12 and the air guide sleeve 11 is welding or integral die forming.

The working principle of the invention is as follows: when the current collector body 1 enters a working state, external air flow enters from the air inlet of the current collector body 1 and is guided by the shell of the guide cover 11, the entering state of the air flow is effectively improved, the air flow is uniformly guided to the inner cavity of the impeller, and the turbulence is effectively reduced.

By adopting the technical scheme of the invention, the air inlet distribution of the inner cavity of the impeller is effectively improved, the turbulence is reduced, the air outlet efficiency of the fan is improved and the noise is reduced.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention.
