Abstract

The invention relates to the design field of power adapters, and particularly relates to a heat radiation structure design of a power adapter. In order to improve the problem of the heat radiation of the power adapter, the invention provides a power adapter which comprises a shell, wherein the shell is provided with a cavity for holding a circuit board, the cavity comprises a main cavity and one or more auxiliary cavities extending from the main cavity, the main cavity is mutually communicated with the auxiliary cavities, and the circuit board comprises a main body board arranged in the main cavity and auxiliary boards arranged in the auxiliary cavities. According to the power adapter provided by the invention, electronic components in the power adapter can be dispersedly arranged in the main cavity and the auxiliary cavities, and therefore the heat generated by the electronic components is easily dispersed. In addition, in order to prevent the heat from accumulating in joints between the main cavity and the auxiliary cavities, the main cavity is mutually communicated with the auxiliary cavities, and the integrity of the cavities is maintained for avoiding causing heat radiation dead angles.

Description

technical field [0001] The invention relates to the design field of power adapters, in particular to the heat dissipation structure design of power adapters. Background technique [0002] For the entire notebook computer, the importance of the power supply is definitely not lower than that of the CPU. The stable operation of the entire notebook computer depends on the continuous supply of stable voltage values ​​by the power supply. Since the notebook computer is generally driven by a DC power supply, and the power supply used by the user is usually an AC power supply, such as a 220-volt alternating current in my country, the notebook computer is usually equipped with a power adapter. The basic working principle of the power adapter is to convert high-voltage alternating current (such as 220-volt alternating current) into low-voltage direct current required by the notebook computer through high-frequency switching technology. During the conversion process of alternating cur...
