[0003] In the use of battery packs, they are increasingly being used as portable energy storage structures. However, most portable energy storage devices in the current technology are composed of multiple battery cells assembled together. For portable energy storage structures, since they are used outdoors, unstable temperature control in hot environments can easily lead to a reduction in battery life. Moreover, most portable batteries in the current technology only use simple ventilation for heat dissipation, which has weak temperature control capabilities. Utility Model Content

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] Combined with appendix Figure 1-3 A battery pack assembly structure includes an outer shell 1 and a sealed top cover 2. The sealed top cover 2 has a handle structure 22 on its top. The outer shell 1 has a control component placement groove 12 on one side. The inner side of the outer shell 1 has multiple battery panel assembly slots 3. The outer shell 1 has water-cooled cooling plates 4 on both sides of the battery panel assembly slots 3, that is, the battery panel assembly slots 3 are set between two water-cooled cooling plates 4 to allow for the assembly and installation of battery panels. In actual installation, it is necessary to leave space and apply sealant. The bottom of the sealed top cover 2 has an auxiliary temperature sensor that works with the battery panel assembly slots 3 to assist in sensing the internal temperature.

[0019] On the other side of the outer casing 1, there is a sealed coolant storage box 5 and a circulation pump 6 that are interconnected. The circulation pump 6 is connected to a first main liquid distribution pipe 7. The water-cooled cooling plate 4 has a flow guide channel 13. The first main liquid distribution pipe 7 has an inlet pipe 8 that is connected to the flow guide channel 13. The end of the flow guide channel 13 away from the inlet pipe 8 has an outlet pipe 9. Multiple outlet pipes 9 are connected to a second main liquid distribution pipe 10. The second main liquid distribution pipe 10 has a return pipe 11 that is connected to the sealed coolant storage box 5, that is, the sealed coolant storage box 5 stores the liquid. Cooling liquid is drawn by circulating pump 6, delivered into the guide channel 13 through the first main distribution pipe 7 and the inlet pipe 8, and then returned through the second main distribution pipe 10 and the return pipe 11. The inlet pipe 8 is equipped with a first one-way valve 14 and a first temperature sensor 15, and the outlet pipe 9 is equipped with a second one-way valve 16 and a second temperature sensor 17. The one-way valve and the temperature sensor 11 can ensure the flow direction and temperature sensing of the cooling liquid, enabling rapid cooling of the assembled solar panel structure and ensuring stable temperature operation, thus guaranteeing the battery's lifespan and safety.

[0020] The sealed coolant storage box 5 is equipped with a semiconductor cooling plate 18 on both the inner and outer sides. The outer shell 1 has a heat dissipation cavity 19 on one side. The semiconductor cooling plate 18 extends to the heat dissipation cavity 19 and is equipped with a metal heat sink 20. The outer shell 1 is equipped with a cooling fan structure 21 that cooperates with the metal heat sink 20. The semiconductor cooling plate 18 is set to perform rapid cooling operation inside the sealed coolant storage box 5. That is, the cold side is set inside the sealed coolant storage box 5, and the hot side is set outside. Heat is dissipated through the metal heat sink 20 and the cooling fan structure 21, which can ensure that the semiconductor cooling plate 18 can perform continuous temperature dissipation operation. At the same time, when the semiconductor cooling plate 18 is actually installed, it is necessary to ensure the sealing between the semiconductor cooling plate 18 and the outer shell 1 to prevent the leakage of coolant.

This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
