Power adapter capable of effectively dissipating heat

Abstract

The invention belongs to the technical field of power adapters, and particularly relates to a power adapter capable of effectively dissipating heat. The power adapter comprises a power adapter body, and a heat dissipation structure is arranged at the top of a protective shell of the power adapter body. The heat dissipation structure comprises an annular frame, a dust filter screen, an insertion rod and a slot, the top of the protective shell of the power adapter body is open, and the slot is formed in the top of the protective shell; the insertion rod is fixedly connected to the bottom of the annular frame, the dust filter screen is fixedly connected to the inner side wall of the annular frame, and the insertion rod is in clearance fit with the slot. Through the cooperative use of the annular frame and the dust filter screen, efficient heat dissipation of the power adapter body can be achieved, external dust can be prevented from entering the protection shell, dust is prevented from being adsorbed on the surfaces of components in the power adapter, and further the heat dissipation of the components is not affected, the components work normally, and the service life of the power adapter is prolonged.

Description

technical field [0001] The invention belongs to the technical field of power adapters, in particular to a power adapter capable of effectively dissipating heat. Background technique [0002] The power adapter is a power conversion device that is widely used in people's daily life, such as mobile phones, computers and battery cars. [0003] In the prior art, the power adapter generally has heat dissipation holes on its housing to achieve heat dissipation for the power adapter. However, with the long-term use of the power adapter, dust will accumulate in the heat dissipation holes, and even dust will block the heat dissipation holes. phenomenon, and thus the effective heat dissipation of the power adapter cannot be achieved; therefore, the present invention provides a power adapter capable of effective heat dissipation. Contents of the invention [0004] In order to make up for the deficiencies of the existing technology and solve the problem in the prior art, the power ada...

Problems solved by technology

[0004] In order to make up for the deficiencies of the existing technology and solve the problem in the prior art, the power adapter generally has cooling holes on its housing to realize the heat dissipation of the power adapter. However, with the long-term use of the power adapter, the heat dissipation holes will accumulate There is dust, even the phenomenon that the dust blocks the heat dissipation holes, and the effective heat dissipation of the power adapter cannot be realized. The invention proposes a power adapter that can effectively dissipate heat
