[0023] Example

[0024] Reference Figure 1-6 A laptop charger heat sink includes a heat exchange base 1, wherein: a cooling fan is fixedly installed at one end of the heat exchange base 1, and a plurality of rectangular frame heat dissipation fins 10 are uniformly fixedly installed on the upper surface of the heat exchange base 1. The plurality of rectangular frame heat dissipation fins 10 are located on the air outlet path of the cooling fan so as to actively cool the rectangular frame heat dissipation fins 10 and the laptop charger 17 through the cooling fan. At least one elastic band 14 for fixing the laptop charger 17 is detachably installed on the heat exchange base 1 so as to fix the laptop charger 17 to the rectangular frame heat dissipation fins 10 of the heat exchange base 1 through the elastic band 14.

[0025] The heat exchange base 1 and the rectangular frame heat dissipation fins 10 adopt existing technologies, such as metal materials (copper, aluminum alloy) and carbon materials (graphene), so as to absorb the heat on the laptop charger 17 during contact with the laptop charger 17, thereby allowing the laptop charger 17 to cool down better.

[0026] Specifically, a trapezoidal cavity 11 is provided at the bottom of the heat exchange base 1, and a ventilation groove 12 is provided through the heat exchange base 1 from the upper surface to the lower surface. The ventilation groove 12 is connected to the trapezoidal cavity 11 to facilitate air circulation and better heat dissipation.

[0027] Specifically, an elastic band mounting hole 13 is provided through the heat exchange base 1. The elastic band mounting hole 13 is vertically connected to the ventilation groove 12. The elastic band 14 is detachably installed in the elastic band mounting hole 13. Both ends of the elastic band 14 extend from both ends of the elastic band mounting hole 13. Through the setting of the elastic band mounting hole 13, the elastic band 14 can be replaced individually, which improves the overall flexibility and convenience.

[0028] Specifically, a number of adjustment holes 15 are evenly distributed through one end of the elastic band 14, and a clip 16 for connecting with the adjustment holes 15 is fixedly installed on the other end of the elastic band 14 so that the size of the ring formed by the elastic band 14 can be adjusted by the clip 16 in conjunction with the adjustment holes 15, thereby facilitating the fixing of various different specifications of laptop chargers 17.

[0029] Specifically, the cooling fan includes a fan isolation protective shell 2, a cover plate 3, an air duct 4, an air outlet 5, a guide pipe 6, a fan 7, an air inlet filter 8, and a fan power cord 9. The fan isolation protective shell 2 is fixedly installed at one end of the heat exchange base 1 to protect the fan 7 and ensure its safety. The top surface of the fan isolation protective shell 2 is flush with the top surface of the rectangular frame heat dissipation fins 10. The other side of the fan isolation protective shell 2 is detachably equipped with a cover plate 3 to facilitate future maintenance of the fan 7. An air duct 4 is fixedly installed inside the fan isolation protective shell 2. The upper part of the fan isolation protective shell 2, near the rectangular frame heat dissipation fins 10, is evenly equipped with air ducts 4. Several air outlets 5 are connected to the inside of the air duct 4. The fan 7 is fixedly installed inside the fan isolation protective shell 2. The air outlet of the fan 7 is connected to the inside of the air duct 4 through the air guide pipe 6. Several air inlet filter holes 8 are evenly opened through the cover plate 3. The position of the air inlet filter holes 8 corresponds to the position of the air inlet of the fan 7. Through the arrangement of the air duct 4, air outlets 5, air guide pipe 6 and air inlet filter holes 8, the fan 7 can draw in external air through the air inlet filter holes 8 and blow it through the air outlets 5 onto the rectangular frame heat dissipation fins 10 and the laptop charger 17 for active air cooling. The fan power cord 9 of the fan 7 passes out from the cover plate 3 for connection to a household power supply.

[0030] Fan 7 uses existing technologies, such as the 12025 cooling fan, DC7025 silent fan, and AC12025 cooling fan.

[0031] In this embodiment, during use, the clip 16 is separated from the adjustment hole 15, at which point the elastic band 14 is in the open state. Then, the laptop charger 17 is placed flat on the rectangular heat dissipation fins 10 of the heat exchange base 1, and then the clip 16 is clipped into the corresponding adjustment hole 15, thereby fixing the laptop charger 17 through the elastic band 14 to ensure the stability of the laptop charger 17.

[0032] Then power is supplied to the fan 7, so that during the operation of the laptop charger 17, the heat will be transferred to the heat dissipation fins 10 of each rectangular frame, and the heat will be dissipated by the air cooling of the fan 7.

[0033] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
