Cell Phone Power supply adapter thermal design

    A large number of high-power semiconductor devices are used in the power adapter. When they work, they will produce a lot of heat. If these heat cannot be released in time through radiator conduction, convection, radiation and other ways, it will produce heat accumulation, heat conduction power supply heating, aging electronic components, and even safety accidents when users use them.

   The wide application of gallium nitride technology in recent two years make the efficiency of chargers reach more than 93%. Most chargers are based on ultra fast charging, small volume and compact design. This kind of product is deeply loved by users, and thermal conductive potting adhesive solution is often used. However, the following requirements should be paid attention to in the selection of heat conductive potting adhesive:  

charger heat dissipation

1. Good thermal conductivity and heat dissipation ability

2. Easy construction and strong adhesion, and benefits for compact design

3. Good flow and sealing

4. High insulation

5. Good stability and strong strecture

   Besides, Adding a small thermal heatsink will also provide a good effect on the electric device cooling issue.  In addition to the design of main parts such as heatsink, a good heat dissipation material can make the whole get twice the result with half the effort.
