A mobile power supply with a heat dissipation fan

Abstract

The utility model discloses a mobile power supply with heat dissipation fan, which comprises an upper shell, a lower shell, a first heat conduction plate, a heat dissipation fan, a passage wall and a second heat conduction plate. The lower shell contains a battery. The first heat conduction plate is fixed to the upper shell to transfer the heat inside the mobile power supply. One end of the first heat conduction plate extends upward to form a mounting boss. The mounting boss is hollowed out to form an airflow cavity. The heat dissipation fan is arranged towards the airflow cavity and fixed to the mounting boss. Multiple passage walls are vertically arranged side by side on the first heat conduction plate. The adjacent passage walls form an airflow channel that is connected to the mounting boss. The second heat conduction plate covers each passage wall. The heat generated by the device to be charged is transferred through the second heat conduction plate, thereby forming a heat dissipation structure outside the mobile power supply shell. Not only can the airflow generated by the heat dissipation fan accelerate the heat dissipation of the mobile power supply and the device, but also can prevent dust from entering the mobile power supply, thereby prolonging the service life of the mobile power supply.
