BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 This is a schematic side sectional view of an embodiment of the present invention. DETAILED DESCRIPTION

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] As attached Figure 1 The heat dissipation module of a modular energy storage device includes an outer shell 1, a frame structure 2 is arranged in the outer shell 1, and the frame structure 2 divides the inner cavity of the outer shell 1 into an air inlet chamber 3, a module insertion chamber 4, a wiring chamber 5, an air distribution chamber 6 and a top chamber 7; a plurality of the module insertion chambers 4 are arranged vertically, the air inlet chamber 3 is located at the bottom side of the plurality of module insertion chambers 4, the wiring chamber 5 is located at the end of the module insertion chamber 4 away from the insertion port, and the two air distribution chambers 6 are respectively located on both sides of the plurality of module insertion chambers 4; the air inlet chamber 3 is connected with the bottom ends of the wiring chamber 5 and the air distribution chamber 6, and the top ends of the wiring chamber 5 and the air distribution chamber 6 are connected with the top chamber 7, and the cavity wall of the top chamber 7 is provided with an exhaust port 8.

[0014] This solution is used as a single module with wide applicability, providing installation space for other modules required to build energy storage equipment, and enabling each module to achieve effective cooling effect. A multi-layer module insertion cavity is vertically arranged to insert modules constituting an energy storage device, such as a battery module, a management module, an auxiliary module, etc. A socket connected to the inserted module is provided on the partition between the module insertion cavity and the wiring cavity, so that the electrical connection of multiple functional modules is realized through the wiring arranged in the wiring cavity, thereby realizing the construction of the energy storage device. Among them, the partition used by the frame structure to separate adjacent module insertion cavities can be adjusted relatively close or far away, and then the cavity size of the module insertion cavity can be adjusted according to the size of the inserted module, and the corresponding socket position is adjusted up and down together with the partition on its bottom side; air is taken in through the bottom air inlet cavity, and is drained to the top cavity along the wiring cavity and the air distribution cavities on both sides, and finally the hot air is discharged from the exhaust port, so that the cooling air flow can vertically pass through the wiring area and both sides of the module insertion area to achieve rapid cooling of the wiring and functional modules. The size of each module insertion cavity can be adaptively designed according to the size of the inserted module, and the number of module insertion cavities can also be set as needed, thereby making the applicability of the heat dissipation module more extensive.

[0015] The wiring cavity 5 is connected to the module insertion cavity 4. A drainage gap 9 is provided on the insertion side of the module insertion cavity 4. Multiple module insertion cavities 4 are connected to the drainage gap 9, and the top of the drainage gap 9 is connected to the top cavity 7. This allows the cooling airflow to flow horizontally through each module insertion cavity during the process of flowing from bottom to top, further improving the heat dissipation effect of the inserted module units.

[0016] The bottom side of the air inlet cavity 3 is provided with an air inlet 31, and the air inlet 31 is provided with a fan 10. By drawing air from the bottom, relatively low-temperature air can be drawn into the cavity, and heat is carried out from the interior of the device in the direction of heat rise. At the same time, it can also play a role in preventing rainwater from entering the interior space, thereby ensuring the safety of the device.

[0017] The connection between the wiring cavity 5 and the module insertion cavity 4 includes several strip-shaped air distribution holes, which are arranged to correspond to the gap between the module insertion cavity 4 and the inserted module. This further precisely constrains the flow path of the cooling airflow, ensuring that the cooling airflow can flow relatively evenly through the gaps surrounding the module, maximizing the contact area between the airflow and the module and enhancing the cooling and heat dissipation effect.

[0018] The air distribution cavity 6 communicates with the module insertion cavity 4. Air guides are provided within the air distribution cavity 6, corresponding to each of the module insertion cavities 4. The bottoms of the air guides slide vertically relative to the cavity walls of the air distribution cavity 6 and can be adjusted with the vertical adjustment of the partitions, ensuring that the air guides are always aligned with the corresponding module insertion cavity. The tops of the air guides are tilted toward the module insertion cavity 4. The exhaust ports 8 are positioned adjacent to the drainage gaps 9. This allows cooling air to enter the module insertion cavity from both sides, flowing toward the wiring cavity and drainage gaps, respectively, before exiting upward into the top cavity. Furthermore, because the wiring cavity is directly fed by cooling air, the majority of air entering the module installation cavity flows toward the drainage gaps, with a smaller portion flowing toward the wiring cavity. This prevents heat from the wiring cavity from being carried into the module insertion cavity and ensures that most of the heat within the module insertion cavity is removed through the drainage gaps. This ensures that both the wiring area and the module installation area receive effective heat dissipation without interfering with each other. This also increases the complexity of the airflow, facilitating rapid heat dissipation.

[0019] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
