[0021] Example 1

[0022] like Figure 1-4 As shown, it is the first embodiment of the present invention, which provides a heat dissipation mechanism for a combined power supply, including a main unit 1, the main unit 1 includes a protective shell 11, the inner cavity of the protective shell 11 is provided with a heat dissipation unit 2, and a heat dissipation slot 3 is opened on the right side of the protective shell 11, the inner cavity of the protective shell 11 is also provided with a power supply body 12, the heat dissipation unit 2 includes a frame 21, and the frame 21 is fixedly connected to the left side of the protective shell 11, the inner cavity of the frame 21 is provided with a fan 22, the bottom of the inner cavity of the protective shell 11 is fixedly connected with a thermal conductive silicone rubber 23, and the bottom of the thermal conductive silicone rubber 23 is fixedly connected with an aluminum bar 24, the aluminum bar 24 passes through the protective shell 11 and extends to the outside of the protective shell 11, and is fixedly connected with a graphite plate 25.

[0023] like Figure 1-4 As shown, the power supply body 12 is protected by the protective shell 11, and the fan 22 can be supported by the frame 21. The fan 22 can absorb external air and blow it into the inner cavity of the protective shell 11 through operation. The surface of the power supply body 12 is dissipated by blowing air, so that the heat is blown away and discharged through the heat dissipation groove 3. At the same time, the thermal conductive silica gel 23 can absorb the heat from the surface of the power supply body 12 and transfer the absorbed heat to the aluminum bar 24. The aluminum bar 24 transfers the heat to the graphite plate 25. Heat is exchanged with the outside through the graphite plate 25 to achieve heat dissipation, which can quickly cool down and dissipate heat for ensuring the safety of the power supply body 12 during operation.

[0024] Example 2

[0025] Reference Figure 1-3 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0026] In this embodiment, there are five aluminum bars 24 , and the five aluminum bars 24 are evenly distributed on the top of the graphite plate 25 . The top of the graphite plate 25 is fixedly connected to the bottom of the protective shell 11 , and the power supply body 12 is located in the inner cavity of the thermal conductive silicone 23 .

[0027] A slot 13 is provided at the upper end of the left side of the protective shell 11 , and a switch button 14 is provided at the lower end of the left side of the protective shell 11 .

[0028] like Figure 1-3 As shown, by setting five aluminum bars 24, the heat absorbed by the thermally conductive silicone 23 can be quickly transferred to the graphite plate 25, which facilitates heat exchange between the graphite plate 25 and the external air, thereby achieving heat dissipation and effectively improving the heat dissipation effect. The slot 13 can facilitate the connection between the external device and the power supply body 12, and the power supply operation of the power supply body 12 can be turned on or off through the switch button 14.

[0029] Example 3

[0030] Reference Figure 1 and 4 , which is the third embodiment of the present utility model, is based on the first two embodiments.

[0031] In this embodiment, a mesh plate 26 is provided on one side of the frame 21 , the number of the heat dissipation slots 3 is eleven, and a filter is fixedly connected to the inner cavity of the heat dissipation slots 3 .

[0032] Screw holes are provided around one side of the frame 21 , and connecting holes 211 are provided in the inner cavities of the screw holes. Bolts 261 are provided around one side of the mesh plate 26 .

[0033] One end of the connecting hole 211 passes through the inner cavity of the bolt 261 and is movably connected to the inner cavity of the bolt 261 . One end of the connecting hole 211 extends to the inner cavity of the screw hole and is threadedly connected to the inner cavity of the thread.

[0034] like Figure 1 and 4 As shown, the fan 22 can be shielded by the mesh plate 26, thereby preventing people from being injured by accidental touching when the fan 22 is operating. At the same time, the mesh plate 26 can intercept dust in the air when the fan 22 is operating to absorb air, preventing dust from entering the inner cavity of the protective shell 11. By taking the connecting hole 211, the connecting hole 211 passes through the inner cavity of the bolt 261, and then rotating the connecting hole 211, one end of the connecting hole 211 will gradually enter the inner cavity of the screw hole and be threadedly connected to the screw hole, thereby realizing the connection between the mesh plate 26 and the frame 21. Conversely, when the connecting hole 211 gradually separates from the inner cavity of the screw hole and the bolt 261, the mesh plate 26 and the frame 21 can be disassembled, which facilitates the cleaning of the mesh plate 26.

[0035] When in use, the power supply body 12 is first limited by the thermal conductive silicone 23, and the protective shell 11 wraps the power supply body 12 to achieve the protection of the power supply body 12. The external device is connected to the power supply body 12 through the slot 13, and the power supply body 12 is turned on or off by the switch button 14 to achieve the power supply operation of the external device. When the power supply body 12 is operating, the fan 22 can be supported by the frame 21, and the fan 22 can be rotated to absorb external air and blow the air into the inner cavity of the protective shell 11. By blowing, the air is blown out. The flow flows on the surface of the power supply body 12, and then the surface of the power supply body 12 can be dissipated to dissipate the heat, so that the heat is gradually blown away and discharged through the heat dissipation groove 3, thereby achieving preliminary heat dissipation. At the same time, the thermal conductive silica gel 23 can absorb the heat on the surface of the power supply body 12, and transfer the absorbed heat to the aluminum strip 24. The aluminum strip 24 transfers the heat to the graphite plate 25, and heat is exchanged with the outside through the graphite plate 25, thereby dissipating the absorbed heat and mixing the heat into the external air, thereby quickly cooling the power supply body 12 and ensuring the safety of the power supply body 12 during operation.

In addition, this application is mainly used to protect mechanical devices, so this application no longer explains the control method and circuit connection in detail.
