[0025] The embodiment of the utility model will be further described in detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but cannot be used to limit the scope of the utility model.

[0026] Example:

[0027] As shown in the accompanying Figure 1 to the accompanying Figure 5 As shown:

[0028] The utility model provides a kind of power supply heat dissipation device, including shell 100, power supply body 101 is provided in shell 100, power supply body 101 is used to charge mobile terminal equipment such as mobile phone, notebook computer, power supply body 101 top is provided with first heat dissipation sheet 104, power supply body 101 bottom is provided with second heat dissipation sheet 105, first heat dissipation sheet 104 and second heat dissipation sheet 105 can be selected copper sheet, copper foil or aluminium sheet etc. metal, by the setting of first heat dissipation sheet 104 and second heat dissipation sheet 105, power supply body 101 can be quickly heat dissipated, the heat generated by power supply body 101 work is quickly conducted to air, realizes heat exchange, first heat dissipation sheet 104 and second heat dissipation sheet 105 surface is provided with multiple groups of convex points 109 respectively, multiple groups of convex points 109 are all with shell 100 inner wall contact, by the setting of convex point 109, shell 100 can be supported, and make first heat dissipation sheet 104 and second heat dissipation sheet 105 and shell 100 form stable and increasing space distance, prevent the temperature rise of shell 100 is higher, first heat dissipation sheet 104 top is provided with first EVA spacer 106, second heat dissipation sheet 105 bottom is provided with second EVA spacer 107.

[0029] Further, the first EVA spacer 106 and the second EVA spacer 107 are made of EVA material, which is ethylene-vinyl acetate copolymer. EVA material is soft and elastic. Its flexibility allows it to be used on the surface of objects of various shapes and curves. EVA spacer can effectively block the transfer of heat. When the power supply body 101 is working, the heat source inside it will generate heat. The first heat sink 104 and the second heat sink 105 are mainly responsible for dissipating heat. If there is no first EVA spacer 106 and second EVA spacer 107, heat will quickly conduct to the shell 100, causing the shell 100 to overheat. The low thermal conductivity of EVA material can reduce the heat conduction from the first heat sink 104 and the second heat sink 105 to the shell 100, keeping the shell 100 at a lower temperature. For example, when the internal power supply temperature of the charger reaches about 70℃, with the first EVA spacer 106 and the second EVA spacer 107, the shell 100 temperature may only rise to about 40℃, while without the spacer, the shell 100 temperature may be as high as 50℃ or even higher.

The first insulating sheet 102 and the second insulating sheet 103 are connected by an insulating tape. Through the cooperation of the first insulating sheet 102, the second insulating sheet 103 and the insulating tape, the power supply body 101 can prevent harm to the user. When the user installs, the power supply body 101 can be connected to the first insulating sheet 102 by screws.

[0032] The bottom of the shell 100 is provided with a heat dissipation net 108, through the arrangement of the heat dissipation net 108, the air in the device can flow, so that better heat dissipation can be achieved, and the second heat dissipation fin 105 is close to the heat dissipation net 108, the contact area of the second heat dissipation fin 105 and the air is increased, and the heat dissipation efficiency of the second heat dissipation fin 105 on the power supply body 101 is improved.
