How to dissipate heat from power adapter

First: reduce the heat generated by the power adapter itself to improve conversion efficiency, but due to technical conditions and cost, the power adapter conversion efficiency is generally around 75%-85%.

Second: the heat dissipation design, the heat dissipation area should be as large as possible, the switching power supply above 100W should generally have a metal perforated casing, or a cooling fan. In order to prevent accidents such as fires caused by temperature, the use of materials requires the use of fire-resistant and high-temperature plastic sealed packages, and the heat generated inside is mainly transmitted through the plastic casing.

Third: When you use the power adapter, try to place the power adapter in a place with good ventilation and heat dissipation. Never put anything like a book on the power supply. As for the feeling that it is not very hot, don't worry
