[0036] The above-mentioned mounting base 10 can be made of a metal material, which can conduct the heat of the mobile phone to the heat dissipation member 20, or can also be made of a plastic material, and an opening is provided in the middle for the installation of the heat dissipation member 20, so that the heat dissipation member 20 can contact the mobile phone and fully absorb the heat of the mobile phone. In some embodiments of the present utility model, the mounting base 10 includes a base body 12 and a heat conducting member 11. An installation opening is provided in the middle of the base body 12, and the heat conducting member 11 is installed in the installation opening for conducting the heat of the mobile phone to the heat dissipation member 20.

[0037] The above-mentioned heat dissipation member 20 is generally made of a metal material such as copper, aluminum or stainless steel, and has good thermal conductivity. The heat dissipation member 20 generally adopts a finned structure to improve the heat dissipation efficiency.

[0038] The heat dissipation fan 30 generally uses an axial flow fan, which can extract the hot air in the heat dissipation gap of the heat sink and discharge it axially away from the mounting base 10. The air inlet direction of the heat dissipation fan 30 can be adjusted by adjusting the position and orientation of the air inlet, and is set according to specific conditions, which is not limited here.
