[0002] When a laptop computer is working, in order to ensure that the laptop computer can continue to work for a long time, it is necessary to use a charger to power the laptop computer while working. As the use time of the laptop computer charger increases, the laptop computer charger will generate a lot of heat, affecting the working efficiency of the laptop computer charger. Therefore, the laptop computer charger needs to be cooled in time.

[0003] At present, when cooling a laptop charger, a heat dissipation bracket is mainly placed at the bottom of the laptop charger to discharge the heat from the laptop charger in a natural heat dissipation manner. Although the heat dissipation bracket can realize convenient heat dissipation of the laptop charger, since the above heat dissipation method is passive heat dissipation, the heat dissipation efficiency of the laptop charger is relatively low. Moreover, after heat dissipation, the heat dissipation bracket of the above structure can neither be conveniently folded together with the laptop charger nor protect the laptop charger from collision after folding, resulting in poor flexibility in the use of the charger heat dissipation device of the above structure.
