[0002] An outdoor energy storage power supply is a device that conveniently stores electrical energy and releases it when needed.

[0027] In order to better understand the technical solutions and beneficial effects of the present disclosure, the present disclosure is further described in detail below with reference to specific embodiments:

[0028] like Figures 1 to 3As shown, it is a heat dissipation structure 10 of the energy storage main control according to an embodiment of the present disclosure, including a main control board 100, a heating inductor 200 and a cooling assembly 300. The cooling assembly 300 includes a fan 310, a connecting column 320 and a thermally conductive silicone sheet 330. The thermally conductive silicone sheet 330 is adhered to one side of the main control board 100. The thermally conductive silicone sheet is a thermally conductive medium material synthesized by using silicone as a base material and adding metal oxides. The heating inductor 200 is arranged on the side of the thermally conductive silicone sheet 330 away from the main control board 100. The heating inductor 200 is electrically connected to the main control board 100. The connecting column 320 is respectively connected to the main control board 100 and the fan 310. The fan 310 is arranged on the side of the heating inductor 200 away from the thermally conductive silicone sheet 330.

[0029] Furthermore, a via 201 is formed in the center of the heating inductor 200, a ventilation hole 101 is opened in the main control board 100 component, and a thermal conductive hole 3301 is opened in the thermal conductive silicone sheet 330. The via 201, the thermal conductive hole 3301 and the ventilation hole 101 are connected in sequence to form a heat dissipation channel.

[0030] In this embodiment, the thermally conductive silicone sheet 330 fills the gap between the heating inductor 200 and the main control board 100. The thermally conductive silicone sheet 330 is in full contact with the contact surface of the heating inductor 200, thereby increasing the heat dissipation speed of the heating inductor 200. The direction of the fan 310 is aligned with the via 201, the thermal conductive hole 3301 and the ventilation hole 101, which are connected in sequence to form a heat dissipation channel for blowing air, so that the heat generated by the heating inductor 200 is quickly dissipated.

[0031] In the heat dissipation structure 10 of the above-mentioned energy storage main controller, the heating inductor 200 is installed on the thermally conductive silicone sheet 330, which accelerates the heat dissipation speed of the heating inductor 200. The thermally conductive silicone sheet 330 also has good shock absorption and insulation effects, thereby improving the safety performance of the heat dissipation structure 10 of the energy storage main controller; the fan 310 blows air to the heating inductor 200, so that the airflow generated by the fan 310 passes through the heat dissipation channel, thereby taking away the heat from the heating inductor 200, the thermally conductive silicone sheet 330 and the main control board 100 structure, improving the heat dissipation efficiency of the heat dissipation structure 10 of the energy storage main controller, and thereby improving the safety performance of the heat dissipation structure 10 of the energy storage main controller.

[0032] like Figure 1 As shown, in one embodiment, the radius of the ventilation hole 101 is larger than the radius of the heat conducting hole 3301. In this embodiment, the larger radius of the ventilation hole 101 allows air to flow out of the ventilation hole 101 more smoothly, and the air carries away heat more quickly, thereby accelerating the heat dissipation.

[0033] like Figure 1As shown in one embodiment, both the heating inductor 200 and the thermally conductive silicone sheet 330 are circular structures. In this embodiment, the circular structure of the heating inductor 200 ensures that heat is evenly distributed around the inductor, avoiding the formation of local overheating areas, thereby improving the working efficiency and stability of the inductor. The circular structure of the thermally conductive silicone sheet 330 ensures a large contact area between the thermally conductive silicone sheet 330 and evenly distributes the contact pressure between the thermally conductive silicone sheet 330 and the heating inductor 200, thereby improving heat conduction efficiency.

[0034] like Figure 1 As shown, in one embodiment, the radius of the thermally conductive silicone sheet 330 is greater than the radius of the heating inductor 200. In this embodiment, the larger radius of the thermally conductive silicone sheet 330 increases the contact area between the thermally conductive silicone sheet 330 and the bottom of the heating inductor 200. More heat is transferred from the heating inductor 200 to the thermally conductive silicone sheet 330, improving the efficiency of heat conduction and making the thermally conductive silicone sheet 330 more effective in dissipating heat from the heating inductor 200.

[0035] like Figure 1 As shown, in one embodiment, the cooling assembly 300 further includes a thermally conductive adhesive layer, which is applied to the bottom of the heating inductor 200 and is used to bond the heating inductor 200 to the thermally conductive silicone sheet 330. In this embodiment, the thermally conductive adhesive layer can fill the gap between the thermally conductive silicone sheet 330 and the heating inductor 200, thereby improving the heat transfer effect of the heating inductor 200 and accelerating the heat dissipation of the heating inductor 200. The thermally conductive adhesive layer also increases the connection strength between the heating inductor 200 and the thermally conductive silicone sheet 330, thereby making the heating inductor 200 more stable.

[0036] like Figure 1 As shown, in one embodiment, the connecting post 320 includes a first screw 340 and a second screw 350. The fan 310 has a first screw hole 3101, and the main control board 100 has a second screw hole 102. The first screw 340 passes through the first screw hole 3101 and is connected to one end of the connecting post 320. The second screw 350 passes through the second screw hole 102 and is connected to the other end of the connecting post 320. In this embodiment, the fan 310 is installed above the heating inductor 200, so that the fan 310 can effectively remove the heat generated by the heating inductor 200. The fan 310 can be disassembled and assembled using the first screw 340, the connecting post 320, and the second screw 350, making it easier to clean and install the fan 310.

[0037] like Figure 1 and Figure 3As shown, in one embodiment, there are at least two connecting posts 320, and the two connecting posts 320 are arranged along the diagonal lines of the fan 310. In this embodiment, the diagonally arranged connecting posts 320 are connected to both ends of the fan 310, so that the two connecting posts 320 distribute the weight of the fan 310 and keep the fan 310 in a horizontal and stable state after installation, thereby reducing the shaking problem caused by the fan 310 during operation.

[0038] like Figure 2 As shown, in one embodiment, the thermally conductive silicone sheet 330 further defines a connection hole 3302, through which the connection end of the heating inductor 200 passes and is connected to the main control board 100. In this embodiment, the connection end of the heating inductor 200 passes through the connection hole 3302, shortening the electrical connection distance between the heating inductor 200 and the main control board 100, thereby saving installation space.

[0039] like Figure 2 As shown, in one embodiment, the cooling assembly 300 further includes a power cable 360 ​​and a quick-connect connector 370. One end of the power cable 360 ​​is connected to the fan 310, and the other end of the power cable 360 ​​is connected to the quick-connect connector 370. The quick-connect connector 370 is used to plug into the power supply interface of the main control board 100. In this embodiment, the fan 310 is powered through the quick-connect connector 370, which facilitates disassembly and maintenance of the fan 310.

[0040] The present application also provides an outdoor energy storage power supply, including the heat dissipation structure 10 of the energy storage controller in any of the above-described embodiments. In this embodiment, air is blown by the fan 310 of the heat dissipation structure 10 of the energy storage controller to the heating inductor 200. The fan's airflow forms a heat dissipation channel through the vias 201, the thermal vias 3301, and the ventilation holes 101, thereby achieving better heat dissipation from the heating inductor 200 and improving the safety performance of the outdoor energy storage power supply.

[0041] Compared with the prior art, the present disclosure has at least the following advantages:

[0042] In the heat dissipation structure 10 of the above-mentioned energy storage main controller, the heating inductor 200 is installed on the thermally conductive silicone sheet 330, which accelerates the heat dissipation speed of the heating inductor 200. The thermally conductive silicone sheet 330 also has good shock absorption and insulation effects, thereby improving the safety performance of the heat dissipation structure 10 of the energy storage main controller; the fan 310 blows air to the heating inductor 200, so that the airflow generated by the fan 310 passes through the heat dissipation channel, thereby taking away the heat from the heating inductor 200, the thermally conductive silicone sheet 330 and the main control board 100 structure, improving the heat dissipation efficiency of the heat dissipation structure 10 of the energy storage main controller, and thereby improving the safety performance of the heat dissipation structure 10 of the energy storage main controller.

[0043] The above-described embodiments merely represent several implementation methods of the present disclosure. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the disclosed patent. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the scope of the present disclosure, all of which fall within the scope of protection of the present disclosure. Therefore, the scope of protection of the disclosed patent shall be determined by the appended claims.
