When the AC-DC integrated power supply is operating, it will generate a large amount of heat. The existing housing of the AC-DC integrated power supply usually opens heat dissipation holes on the housing for natural heat dissipation. This heat dissipation method has poor heat dissipation effect, and external dust can easily enter the inside of the housing through the heat dissipation holes and adhere to the electronic devices inside the housing, affecting the heat dissipation of the electronic devices.

[0003] Therefore, we design an AC-DC integrated power supply and its housing here. Content of the Utility Model
