Power adapter with radiating pins

Abstract

The present application provides a power adapter with pins dissipating heat, which is used to conduct part of the heat generated by an internal device to the pins through a heat-conducting structure, so as to dissipate this part of the heat through the pins, effectively reducing the temperature of the adapter shell and the internal devices. temperature. The power adapter of the embodiment of the present application includes: an adapter shell, a circuit structure, pins and a heat conduction structure; the adapter shell has a cavity for accommodating the circuit structure and a pin hole; the pin is arranged in the pin hole, and the circuit structure is arranged in the cavity , the circuit structure includes a printed circuit board PCB and internal components arranged on the PCB; the heat conduction structure is connected with the internal components and pins.

Description

technical field [0001] The present application relates to the field of power adapters, in particular to a power adapter with pin heat dissipation. Background technique [0002] Power adapters are widely used in consumer electronic products such as smartphones, tablet computers, and notebook computers. With the increasing battery capacity of electronic products, consumers have higher and higher demands for fast charging. In order to shorten the charging time of such consumer electronic products, generally This is achieved by increasing the charging power of the power adapter. In recent years, the charging power of power adapters has increased significantly. Taking smartphone adapters as an example, the charging power has increased from 5W to 10W, and even as high as 20W or more. One challenge brought about by the increase in the charging power of the power adapter is the heat dissipation of the adapter. The power adapter generally uses natural heat dissipation to meet the ne...

[0004] but, figure 1 The natural heat dissipation capability of the power adapter shown is limited by the size of the adapter, and can only be applied to power adapters with low heat dissipation density. The adapter shell is generally made of plastic, and plastic has a low thermal conductivity and poor temperature uniformity, which will cause The local hot spot temperature of the adapter shell is high, and because the internal components of the adapter do not conduct heat effectively, the temperature of the internal components is high, which affects the life of the components; figure 2 The power adapter shown is generally made of plastic because the adapter shell is generally made of plastic, and the thermal conductivity is low. The local hot spot temperature of the adapter shell has a limited effect on temperature uniformity, and the overall heat dissipation capacity of the adapter cannot be greatly improved; image 3 The heat dissipation function of the power adapter shown is limited by the filling amount of the potting heat-conducting material and the heat capacity of the material itself. It is only suitable for power adapters with a short duration of high-power charging. For power adapters with a long time of high-power charging , can not effectively reduce the temperature of the adapter shell
