Description

Technical Field

[0001] The utility model relates to the field of power adapters, in particular to a lightweight power adapter with high heat dissipation efficiency. Background Art

[0002] With the increasing popularity of electronic products, power adapters, as an important part of electronic products, have gradually attracted people's attention in terms of power consumption and heat generation. Traditional power adapters will generate a certain amount of heat when working. This is because the internal components of the power adapter (such as transformers, capacitors, inductors, etc.) will generate losses and heat in the process of converting electrical energy. In addition, power adapters with higher power are also prone to generate more heat under high load conditions. If the power adapter generates too much heat, it may affect its stability and safety, and even shorten its life. Therefore, it is very important to design a reasonable heat dissipation structure and adopt effective heat dissipation technology, which can improve the heat dissipation efficiency and ensure the normal and stable operation of the power adapter. Therefore, in order to solve the problem of high temperature and heat generation of the power adapter, the development of a power adapter with high heat dissipation efficiency has become an urgent technical challenge.
