Abstract

A power adapter heat dissipation structure disclosed by the present invention comprises a heat conduction member, a semiconductor cooler and a heat dissipation member, the heat conduction member is attached to an electronic element of a power adapter, the heat dissipation member is arranged on the outer wall of a shell of the power adapter, and the shell is provided with a hole for the heat conduction of the hot end of the semiconductor cooler and the heat dissipation member. And the cold end of the semiconductor cooler is in thermal conduction with the heat conduction piece. According to the heat dissipation structure of the power adapter, heat generated by the electronic elements of the power adapter during working is directionally conducted out of the shell from the interior of the shell to be dissipated, the heat is prevented from being accumulated in the shell, it is guaranteed that the electronic elements work at the proper temperature, the working stability is guaranteed, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of power adapters, in particular to a heat dissipation structure for a power adapter. Background technique [0002] The power adapter is a power supply conversion device for small portable electronic equipment and electronic appliances. It is generally composed of housings, transformers, inductors, capacitors, control ICs, PCB boards and other components. Its working principle is converted from AC input to DC output. It is often used in devices such as mobile phones, LCD monitors and laptops. [0003] During the use of electrical appliances, the power adapter itself will generate heat, especially when the electrical appliances are working at full load, the heat generated by the power adapter is extremely high. The existing power adapters usually have electronic components installed in plastic shells. The heat dissipation effect of the body is poor, and the heat will accumulate inside the shell to cause the ...
