[0002] Laptop cooling devices are typically stands with fans, on which laptops can be placed. They work by having the fan on the stand blow air directly onto the bottom of the laptop, increasing airflow and thus removing heat.

[0003] The fans on existing laptop auxiliary cooling devices are usually not adjustable in position. However, different laptops generate heat in different locations, and the airflow direction of the fans on existing laptop auxiliary cooling devices is not adjustable. Therefore, existing cooling devices cannot specifically cool the heat-generating areas of a particular laptop, resulting in a limited range of applications. Utility Model Content

The support mechanism includes a support base, which is U-shaped, and a metal ventilation mesh plate is fixed on the inner side of the support base.

The fan and the temperature sensor are electrically connected to the MCU. A magnet is provided at the end of the patch away from the fan, and the patch is magnetically attracted to the metal ventilation mesh plate by the magnet. A insert is fixed at the end of the patch near the fan, and the insert is snapped into the edge groove, so that the patch can be fixed on the mesh cover.

[0006] Preferably, the metal ventilation mesh plate has several ventilation holes that penetrate both sides of it, and the several ventilation holes are evenly distributed on the metal ventilation mesh plate.

[0007] Preferably, two limiting blocks are fixed on the upper end face of the support base, and the two limiting blocks are symmetrical about the support base.

[0008] Preferably, it also includes an adjustment mechanism, which includes a storage seat and an inclined support rod. There are two storage seats, and each of the two storage seats is provided with a first rotating shaft. The two storage seats are respectively connected to the support seat through the two first rotating shafts, and the two storage seats are connected by a reinforcing rib.

[0009] Preferably, multiple slots are provided on both storage seats, and the end of the inclined support rod away from the support seat is engaged in the slot.

[0010] Preferably, the inclined support rod is U-shaped, and each end of the inclined support rod is provided with a second pivot, and the inclined support rod is connected to the support base through the second pivot at each end.

[0016] 2. This utility model, through the setting of a temperature sensor and MCU, the temperature sensor monitors the temperature near the bottom of the laptop in real time and transmits an electrical signal to the MCU, so that the MCU can intelligently adjust the fan speed, so as to adjust the fan speed according to the different temperatures of the laptop, and obtain a quieter experience when the laptop temperature is low.

[0017] 3. By removing the two patches from the mesh cover and then removing the fan from the four sockets, rotating the fan 180°, and reinstalling it back onto the four sockets, the fan's airflow direction can be reversed.
