Description

Technical Field

[0001] This utility model relates to the field of heat dissipation mechanism technology, and more specifically, to a multi-zone heat dissipation mechanism for energy storage cabinets. Background Technology

[0002] The basic components of an energy storage cabinet include battery packs, a controller, a converter, and a monitoring system. The battery packs store electrical energy, the controller manages the charging and discharging process, the converter converts DC power to AC power, and the monitoring system monitors and manages the operating status of the energy storage cabinet in real time. The battery pack is the core component of the energy storage cabinet, used for storing electrical energy. Common battery types include lead-acid batteries, lithium-ion batteries, and sodium-sulfur batteries. These batteries are selected based on different needs and application scenarios to provide optimal energy storage performance. Battery packs typically consist of multiple battery cells connected in series or parallel. The energy storage cabinet integrates multiple batteries, which generate a large amount of heat during charging and discharging. Therefore, thermal management and fire suppression are two crucial technologies for energy storage cabinets. If thermal runaway occurs in one battery cluster inside the energy storage cabinet, it can easily cause the temperature of surrounding battery clusters to rise, leading to a chain reaction; therefore, heat dissipation is necessary.

[0003] Among them, the patent with announcement number CN221687632U discloses a heat dissipation mechanism for an energy storage cabinet, including a cabinet body, a base frame fixedly connected to the bottom of the cabinet body, a partition fixedly connected to the inside of the cabinet body, four racks placed inside the cabinet body, multiple aluminum plates evenly fixedly connected to the inner walls of the four racks, multiple heat-conducting blocks fixedly connected between two aluminum plates, and a battery placed on the top of the aluminum plates.

[0004] When in use, this structure consists of an aluminum plate, heat-conducting blocks, a battery, a side door, an inlet plate, an L-shaped protective plate, an outlet pipe, a U-shaped pipe, an air inlet filter, and a cooling fan. The battery transfers heat through the aluminum plate and multiple heat-conducting blocks to prevent localized overheating. However, this structure is not easy to perform zoned heat dissipation in different areas, resulting in limitations in heat dissipation, as it can only dissipate heat in a specific location. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a multi-zone heat dissipation mechanism for energy storage cabinets, which aims to solve the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a multi-zone heat dissipation mechanism for an energy storage cabinet, including a water guide frame, on which a diversion heat dissipation component is provided;

[0007] The heat dissipation assembly includes several diversion pipes disposed within the water guide frame, and each diversion pipe is connected to the water guide frame. The multiple diversion pipes are arranged side by side, and a wave guide plate is disposed between each pair of adjacent diversion pipes.

[0008] The bottom of the water guide frame is provided with an air gathering frame, and the bottom of the air gathering frame is provided with a number of exhaust pipes.

[0009] Optionally, in one possible implementation, a water tank is provided on one side of the water guide frame, and two connectors are provided on the end of the water guide frame facing the water tank. Multiple connectors are connected to the water guide frame, and each connector is provided with a water guide pipe. One end of each of the two water guide pipes extends to the water tank and is connected to the water tank. The two water guide pipes are arranged side by side, and a water pump for transporting the medium is provided on one of the water guide pipes. A protective frame is provided on the top of the water guide frame, and an air-cooled radiator for heat dissipation is provided inside the protective frame.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] By setting up multiple exhaust pipes distributed at the bottom of the gas-gathering frame, air cooling and hot air extraction can be carried out separately for battery clusters in different areas, which solves the limitation of existing technologies that can only dissipate heat in a single area and effectively avoids the risk of thermal runaway caused by excessive local temperature.

[0012] The corrugated baffles between adjacent ducts guide the airflow along the corrugated path, increasing the contact time and area between the airflow and the ducts, thus enhancing heat exchange efficiency. At the same time, the liquid cooling circulation system and the air-cooled radiator work together to achieve a dual heat dissipation mode, significantly improving the heat dissipation rate and ensuring that the temperature inside the energy storage cabinet remains stable within a safe range.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1

[0021] This embodiment discloses a multi-zone heat dissipation mechanism for energy storage cabinets, which aims to achieve precise heat dissipation in multiple zones within the energy storage cabinet through the synergistic effect of liquid cooling and air cooling, thereby overcoming the limitation of existing heat dissipation mechanisms that can only dissipate heat in a single zone.

[0022] like Figure 1 As shown, the heat dissipation mechanism includes a water guide frame 1, which is a rectangular hollow frame structure. It integrates a diversion heat dissipation component inside, which is used to dissipate heat from battery clusters in different areas of the energy storage cabinet.

[0023] like Figure 1 , Figure 4 As shown, the system includes several diversion conduits 2 disposed within the water guide frame 1. Each diversion conduit 2 is a hollow copper tube, arranged side-by-side at intervals along the length of the water guide frame 1, and both ends of each diversion conduit 2 are connected to the internal cavity of the water guide frame 1 to achieve the diversion and delivery of coolant. A corrugated baffle 3 is vertically arranged between two adjacent diversion conduits 2, the function of which is to guide the airflow in the energy storage cabinet along the corrugated path, increase the contact time between the airflow and the diversion conduits 2, and improve the heat exchange efficiency.

[0024] like Figure 2 As shown, the bottom of the water guide frame 1 is fixedly connected to the air gathering frame 4 by bolts. Several exhaust pipes 5 are evenly distributed at the bottom of the air gathering frame 4. One end of the exhaust pipe 5 can extend to different battery cluster areas inside the energy storage cabinet, such as the gaps between battery packs, to directionally discharge the hot air collected by the air gathering frame 4 to the outside of the energy storage cabinet. Furthermore, a one-way valve can be provided at the connection between the exhaust pipe 5 and the air gathering frame 4 to prevent backflow of external airflow.

[0025] like Figure 3 , Figure 4As shown, a water tank 6 is installed on one side of the water guide frame 1. Two connectors 7 are welded to the end of the water guide frame 1 facing the water tank 6. Each connector 7 is connected to a water guide pipe 8. The other end of each water guide pipe 8 is connected to the inlet and outlet of the water tank 6, forming a closed-loop pipeline. A water pump 9, such as model ISG50-160, is connected in series on one of the water guide pipes 8. Its function is to provide power for the coolant, pumping the low-temperature coolant in the water tank 6 into the water guide frame 1 and driving the coolant in the circulation system to flow continuously.

[0026] like Figure 1 , Figure 3 As shown, a protective frame 10 is provided on the top of the water guide frame 1. An air-cooled radiator 11, such as model FSA-8025, is installed inside the protective frame 10. Its air outlet faces the top of the water guide frame 1. Its function is to cool the coolant that has absorbed heat in the water guide frame 1 through forced air cooling, and at the same time accelerate the flow of hot air around the water guide frame 1 to form a synergistic heat dissipation with the liquid cooling system.

[0027] The specific working principle is as follows: after the water pump 9 starts, the low-temperature coolant in the water tank 6 is pumped into the connector 7 of the water guide frame 1 through the water guide pipe 8. After the coolant enters the internal cavity of the water guide frame 1, it is evenly distributed into several parallel distribution pipes 2.

[0028] When the hot airflow inside the energy storage cabinet flows under natural convection or the action of an external fan, it is guided by the corrugated guide plate 3 between adjacent diversion ducts 2, flowing along a corrugated path. This design increases the contact time and contact area between the airflow and the diversion ducts 2, further improving the heat exchange efficiency and allowing the diversion ducts 2 to absorb more ambient heat.

[0029] The hot air from the contact between the battery clusters will gather in the gas-gathering frame 4. The gas-gathering frame 4 has several exhaust pipes 5 distributed at the bottom. The exhaust pipes 5 can extend to the gaps between different battery clusters to directionally discharge the hot air to the outside of the energy storage cabinet, so as to avoid the accumulation of hot air in the cabinet and the resulting local temperature rise.

[0030] After absorbing heat, the high-temperature coolant flows back from the distribution pipe 2 to the water guide frame 1. The air-cooled radiator 11 inside the top protective frame 10 of the water guide frame 1 is activated, forcibly cooling the high-temperature coolant inside the water guide frame 1. The cooled coolant then flows back to the water tank 6 through another water guide pipe 8, completing one cycle. Driven continuously by the water pump 9, the above process is repeated, achieving continuous and efficient heat dissipation for multiple areas within the energy storage cabinet.

[0031] Conversely, the airflow delivered by the air-cooled radiator 11 is cooled by the coolant and then gathered by the air-gathering frame 4 before being discharged to different areas through the exhaust pipe 5.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
