[0044] Refer to Figures 1-3 As shown, this embodiment provides an energy storage cabinet that is convenient for heat dissipation, including:

[0045] Battery cabinet 100, the battery cabinet 100 includes a liquid cooling part and an air cooling part, and the liquid cooling part is located on one side inside the battery cabinet 100, and the air cooling part is located on the other side inside the battery cabinet 100;

[0046] Battery packs 110 and battery placement bins 120, the battery placement bin group is located inside the battery cabinet 100, the battery placement bin group includes a plurality of uniformly arranged battery placement bins 120, there is a gap between adjacent two battery placement bins 120, the battery placement bins 120 are arranged towards the air cooling part, and each battery placement bin 120 is internally provided with a battery pack 110;

[0047] Support frame, arranged inside the battery placement bin 120 along a direction parallel to the length direction of the battery placement bin 120, the support frame includes a cuboid frame 131 and a plurality of connecting rods 132, the cuboid frame 131 is sleeved outside the battery pack 110, one end of the connecting rod 132 is connected to the cuboid frame 131, and the other end of the connecting rod 132 is connected to the inner wall of the battery placement bin 120;

[0048] Liquid cooling assembly, located outside the battery placement bin 120 and outside the battery cabinet 100;

[0049] Air cooling assembly, located outside the air cooling part and outside the battery cabinet 100;

[0050] First sliding assembly, arranged between the battery placement bin group and the inner bottom wall of the battery cabinet 100 along a direction parallel to the length direction of the battery cabinet 100;

[0051] Second sliding assembly, arranged between the battery placement bin group and the inner top wall of the battery cabinet 100 along a direction parallel to the length direction of the battery cabinet 100.

[0052] It can be seen that the battery cabinet 100 is used to store and manage the battery packs 110, and the battery placement bin group provides an independent storage space for each battery pack 110. Through this structural design, each battery pack 110 can be effectively isolated, reducing heat conduction and heat accumulation, thereby improving the safety and stability of the entire energy storage system. The liquid cooling component includes a liquid cooling pipe 141, a telescopic pipe group 142, a liquid cooling water tank 143, and a condensation return pipeline 144. The liquid cooling pipe 141 runs through both sides of the battery pack 110, and the heat generated by the battery pack 110 is carried away by the flow of the coolant inside the liquid cooling pipe 141. The telescopic pipe group 142 is used to connect the liquid cooling pipe 141 and the liquid cooling water tank 143 to ensure adaptability during the sliding process of the battery placement bin group. The condensation return pipeline 144 leads the coolant from the liquid cooling water tank 143 back to the liquid cooling pipe 141, forming a closed circulation system. The air cooling component includes a fan group 151 and a second temperature sensor 152. The fan group 151 is arranged in the air cooling part and is used to blow the cold air in the cold air box 154 towards the battery pack 110 to enhance the heat dissipation effect. The second temperature sensor 152 is used to monitor the temperature of the air cooling part to ensure that the fan group 151 operates at an appropriate temperature.

[0053] It can be seen that the first sliding component and the second sliding component enable the battery placement bin group to slide along the length direction inside the battery cabinet 100, facilitating the installation and maintenance of the battery packs 110. The first slide rail 161 and the second slide rail 171 are respectively fixed on the inner bottom wall and the inner top wall of the battery cabinet 100, while the first slider 162 and the second slider 172 are respectively connected to the bottom end and the top end of the battery placement bin group. Through the sliding component, the battery placement bin group can be easily pulled out from the battery cabinet 100 for the replacement or maintenance of the battery pack 110. The control device is the control center of the entire energy storage cabinet. It is electrically connected to the liquid cooling component, the air cooling component, the first sliding component, the second sliding component, as well as the first temperature sensor and the second temperature sensor 152. The temperature control module inside the control device can automatically adjust the working states of the liquid cooling component and the air cooling component according to the feedback information of the temperature sensors to ensure that the battery pack 110 operates within the optimal temperature range. The display screen is used to display the working state and temperature information of the energy storage cabinet in real time, facilitating the monitoring and management by the operator.

[0054] It can be understood that the energy storage cabinet facilitating heat dissipation in this embodiment effectively improves the heat dissipation efficiency of the battery pack 110 through the combination of liquid cooling and air cooling, ensuring the safe and stable operation of the energy storage system. At the same time, the design of the sliding component makes the maintenance of the battery pack 110 more convenient, and the intelligent management of the control device further improves the usage efficiency and reliability of the energy storage cabinet.

[0055] Specifically, the liquid cooling component includes:

[0056] The liquid cooling pipe 141 is arranged around the outer wall of the battery placement bin 120;

[0057] The telescopic pipe group 142 includes a first telescopic pipe and a second telescopic pipe. One end of the first telescopic pipe is connected to the water inlet end of the liquid cooling pipe 141, and one end of the second telescopic pipe is connected to the water outlet end of the liquid cooling pipe 141. The other ends of the first telescopic pipe and the second telescopic pipe both extend out of the battery cabinet 100;

[0058] The liquid cooling water tank 143 is located outside the battery cabinet 100. One end of the liquid cooling water tank 143 is respectively connected to the other ends of the first telescopic pipe and the second telescopic pipe, and a condensation return pipeline 144 is arranged at the other end of the liquid cooling water tank 143.

[0059] It can be seen that through the design of the liquid cooling pipe 141 surrounding the outer wall of the battery placement bin 120, it is ensured that the coolant can evenly cover the surface of the battery pack 110, thus realizing efficient heat exchange. The design of the telescopic pipe group 142 enables the liquid cooling system to still maintain good sealing performance and flexibility when the battery placement bin group slides, ensuring that the coolant circulation is not affected. The liquid cooling water tank 143, as the storage and regulation center of the coolant, its capacity and design directly affect the performance of the entire liquid cooling system. The condensation return pipeline 144 is responsible for leading the coolant from the liquid cooling water tank 143 back to the liquid cooling pipe 141, ensuring that the coolant circulates in the system, thereby continuously taking away the heat generated by the battery pack 110.

[0060] Specifically, the liquid cooling assembly further includes:

[0061] The first temperature sensor is located inside the liquid cooling part.

[0062] It can be seen that the first temperature sensor is used to monitor the temperature of the liquid cooling part in real time, ensuring that the coolant works within an appropriate temperature range. When the temperature is too high, the first temperature sensor will send a signal to the control device, and the control device will immediately adjust the working state of the liquid cooling assembly, such as increasing the flow rate of the coolant or lowering the temperature of the coolant, to ensure the heat dissipation effect of the battery pack 110.

[0063] Specifically, the air cooling assembly includes:

[0064] The fan group 151 is located inside the air cooling part. The fan group 151 includes several fans, and several fans are evenly distributed on one inner wall of the air cooling part;

[0065] The second temperature sensor 152 is located inside the air cooling part.

[0066] It can be seen that through its evenly distributed design, the fan group 151 ensures that the cold air can be evenly blown towards each battery pack 110, thereby improving the overall heat dissipation efficiency. The operation of the fan group 151 is monitored in real time by the second temperature sensor 152. When the temperature of the air-cooled part is detected to exceed the set value, the second temperature sensor 152 sends a signal to the control device, and the control device immediately starts or adjusts the working state of the fan group 151 to ensure that the battery pack 110 operates within a safe temperature range.

[0067] Specifically, the air-cooled component further includes:

[0068] A cold air input pipe 153, located outside the battery cabinet 100. One end of the cold air input pipe 153 is connected to the fan group 151, and the other end extends to the outside of the battery cabinet 100;

[0069] A cold air box 154, located outside the battery cabinet 100. The cold air box 154 has an air inlet and an air outlet. The air inlet is connected to the other end of the cold air input pipe 153, and a cooling device for cooling the air entering the inside of the cold air box 154 is provided inside the cold air box 154.

[0070] It can be seen that the cold air input pipe 153 introduces the external cold air into the battery cabinet 100 to ensure that the fan group 151 has sufficient cold air for heat dissipation. As a storage and regulation device for cold air, the internal cooling device of the cold air box 154 can further reduce the temperature of the air entering the battery cabinet 100, thereby improving the heat dissipation effect. The design of the air inlet and air outlet of the cold air box 154 enables the cold air to smoothly pass through the battery cabinet 100 and take away the heat generated by the battery pack 110. In addition, the cooling device of the cold air box 154 can be any form of cooling equipment, such as an evaporative cooler or a heat exchanger, to adapt to different usage environments and heat dissipation requirements.

[0071] Specifically, the first sliding component includes:

[0072] A first slide rail 161, arranged on the inner bottom wall of the battery cabinet 100 along a direction parallel to the length direction of the battery cabinet 100;

[0073] A first slider 162, with one end slidably connected to the first slide rail 161, and the other end of the slider connected to the bottom end of the battery placement bin group.

[0074] Specifically, the second sliding component includes:

[0075] A second slide rail 171, arranged on the inner top wall of the battery cabinet 100 along a direction parallel to the length direction of the battery cabinet 100;

[0076] A second slider 172, with one end slidably connected to the second slide rail 171, and the other end of the slider connected to the top end of the battery placement bin group.

[0077] It can be seen that the design of the first slide rail 161 and the second slide rail 171 enables the battery placement bin group to slide along the length direction within the battery cabinet 100, thus facilitating the installation and maintenance of the battery pack 110. The first slider 162 and the second slider 172 are respectively connected to the bottom end and the top end of the battery placement bin group, ensuring the stability and reliability of the sliding assembly. In actual operation, the user only needs to gently pull the battery placement bin group to pull it out of the battery cabinet 100, greatly simplifying the maintenance process.

[0078] Specifically, the energy storage cabinet facilitating heat dissipation further includes:

[0079] A control device, located on the outer side wall of the battery cabinet 100, is electrically connected to the first temperature sensor, the second temperature sensor 152, the liquid cooling component, the air cooling component, the first sliding component, and the second sliding component.

[0080] Specifically, a temperature control module is provided inside the control device, and the control device further includes:

[0081] A display screen, located on the outer side wall of the battery cabinet 100.

[0082] It can be seen that the control device, as the intelligent core of the entire energy storage cabinet, is used to coordinate and manage the working states of each component. The temperature control module receives the data from the first temperature sensor and the second temperature sensor 152 in real time, and automatically adjusts the operating parameters of the liquid cooling and air cooling systems according to the temperatures of the battery pack 110 and the air cooling part. In addition, the control device also has a fault diagnosis function, which can timely detect and handle potential heat dissipation problems to ensure the stable operation of the energy storage system. The display screen provides an intuitive interface for the operator, and real-time displays the working state and temperature information of the energy storage cabinet. Through the display screen, the operator can easily monitor the temperature of the battery pack 110, the operating states of the liquid cooling and air cooling systems, and key information such as the position of the sliding component. When an abnormality occurs in the system, the display screen will display corresponding warning information to prompt the operator to take corresponding measures.

[0083] In summary, the energy storage cabinet facilitating heat dissipation in this embodiment effectively improves the heat dissipation efficiency of the battery pack 110 through the combination of liquid cooling and air cooling, ensuring the safe and stable operation of the energy storage system. At the same time, the design of the sliding component makes the maintenance of the battery pack 110 more convenient, and the intelligent management of the control device further improves the usage efficiency and reliability of the energy storage cabinet.
