Abstract
Description
Technical Field
[0001] This utility model relates to the field of energy storage cabinet technology, and more specifically, to an outdoor energy storage cabinet. Background Technology
[0002] With the rapid development of new energy technologies, energy storage cabinets, as an important component of the power system, are widely used in outdoor scenarios such as photovoltaic power plants, wind farms, and distributed energy storage systems. However, traditional outdoor energy storage cabinets suffer from insufficient heat dissipation efficiency during actual operation, especially in high-temperature seasons. The heat generated by the energy storage equipment during continuous operation is difficult to dissipate quickly, leading to increased internal temperature and affecting battery life and system stability. Traditional heat dissipation solutions often rely on single air cooling or compressor cooling. The former has limited heat dissipation capacity, while the latter has high energy consumption and complex structure, making it difficult to balance high efficiency and energy saving requirements. Open-type heat dissipation systems are prone to introducing external dust and particulate matter, which can accumulate over time, potentially clogging air ducts, corroding electronic components, reducing equipment reliability, and increasing maintenance costs. Utility Model Content
[0003] To solve the above-mentioned technical problems, this utility model provides an outdoor energy storage cabinet. A longitudinally extending partition plate is installed in the middle of the cabinet's internal cavity, dividing the cabinet's internal cavity into a first chamber and a second chamber. A gap is left between the bottom end of the partition plate and the bottom of the cabinet's internal cavity to form a channel. An airflow replacement chamber is installed on the top of the cabinet, and a cooling mechanism is installed in the inner cavity of the airflow replacement chamber. A first slot communicating with the interior of the airflow replacement chamber is opened on the top of the first chamber, and a second slot communicating with the interior of the airflow replacement chamber is opened on the top of the second chamber. The air inside the cabinet circulates through the first chamber, the channel, the second chamber, the second slot, and the airflow replacement chamber, and then enters the first chamber from the first slot for circulation.
[0004] In a preferred embodiment, a vacuum chamber heat spreader is installed inside the airflow displacement chamber, which divides the airflow displacement chamber into a front chamber and a rear chamber. The front chamber and the rear chamber are not connected. The cooling mechanism is installed inside the front chamber, and the first slot and the second slot are connected to the interior of the front chamber.
[0005] In a preferred embodiment, the cooling mechanism includes two sets of symmetrically arranged fins located inside the front chamber. Each set of fins consists of multiple fins, all of which are fixed to the surface of the vapor chamber heat exchange plate. A gap is left between the two sets of fins, and a drainage fan is installed in the gap.
[0006] In a preferred embodiment, the rear chamber is provided with a plurality of semiconductor cooling chips, the cold ends of which are attached to the surface of the vacuum chamber heat exchange plate, and the hot ends of which face the rear chamber.
[0007] In a preferred embodiment, the outer wall of the airflow replacement chamber facing the rear chamber has several ventilation slots, and symmetrically arranged air intake fans and air exhaust fans are installed inside the rear chamber, with the air intake fans and air exhaust fans attached to the inner wall of the rear chamber on the inner side of the ventilation slots.
[0008] The technical effects and advantages of this utility model are as follows:
[0009] This invention combines forced air cooling and semiconductor refrigeration, with a dual heat dissipation mechanism that significantly improves cooling efficiency and adapts to high-temperature outdoor environments.

Detailed Implementation
[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.
[0016] like Figure 1-4An outdoor energy storage cabinet is shown, in which a longitudinally extending partition plate 2 is installed in the middle of the inner cavity of the cabinet body 1. The partition plate 2 divides the inner cavity of the cabinet body 1 into a first chamber 3 and a second chamber 4. A gap is left between the bottom end of the partition plate 2 and the bottom of the inner cavity of the cabinet body 1 to form a channel 5. An airflow replacement chamber 6 is installed on the top of the cabinet body 1. A cooling mechanism is installed in the inner cavity of the airflow replacement chamber 6. A first slot 7 communicating with the inside of the airflow replacement chamber 6 is opened on the top of the first chamber 3. A second slot 8 communicating with the inside of the airflow replacement chamber 6 is opened on the top of the second chamber 4. After the air inside the cabinet body 1 circulates through the first chamber 3, the channel 5, the second chamber 4, the second slot 8, and the airflow replacement chamber 6, it enters the first chamber 3 from the first slot 7 and circulates.
[0017] Based on the above, the internal partition 2 of the cabinet 1 divides the cavity into a first chamber 3 and a second chamber 4, and the bottom channel 5 connects the two chambers. Air enters the second chamber 4 from the first chamber 3 through the bottom channel 5, and then rises to the airflow replacement chamber 6 at the top through the second slot 8. After being cooled, it returns to the first chamber 3 through the first slot 7, forming a closed loop.
[0018] The airflow replacement chamber 6 is equipped with a vacuum chamber heat spreader 9, which divides the interior of the airflow replacement chamber 6 into a front chamber 10 and a rear chamber 11. The front chamber 10 and the rear chamber 11 are not connected. The cooling mechanism is installed inside the front chamber 10, and the first slot 7 and the second slot 8 are connected to the interior of the front chamber 10.
[0019] Based on the above, the air circulating inside the cabinet 1 will only enter the front chamber 10. Inside the front chamber 10, the air will be cooled by the cooling mechanism and then circulated from the second slot 8 into the second chamber 4 inside the cabinet 1.
[0020] The cooling mechanism includes two sets of symmetrically arranged fins 12 located inside the front chamber 10. Each set of fins 12 consists of multiple fins and is fixed on the surface of the vacuum chamber heat exchange plate 9. A gap is left between the two sets of fins 12 and a drainage fan 13 is installed in the gap.
[0021] When the airflow fan 13 is working, it guides the airflow from the first slot 7 to the second slot 8. During this process, the airflow passes through the gaps between several fins 12 in sequence. During this process, it exchanges heat with the fins 12 and cools down. The cooled air is then circulated from the second slot 8 into the cabinet 1.
[0022] The rear chamber 11 is provided with a plurality of semiconductor cooling chips 14. The cold end of the semiconductor cooling chip 14 is attached to the surface of the vacuum chamber heat spreader 9, and the hot end of the semiconductor cooling chip 14 faces the rear chamber 11.
[0023] The vacuum chamber heat exchanger 9 isolates the front chamber 10 from the rear chamber 11. At the same time, the vacuum chamber heat exchanger 9 efficiently conducts heat, ensuring that the heat dissipation of the front chamber 10 and the cooling of the rear chamber 11 work together. The cold end of the semiconductor cooling chip 14 of the rear chamber 11 is attached to the vacuum chamber heat exchanger 9, absorbs heat and discharges it to the rear chamber 11 through the hot end.
[0024] Based on the above, during operation, the cold end of the semiconductor cooling chip 14 cools the vacuum chamber heat spreader 9 by absorbing heat and cooling it down. The vacuum chamber heat spreader 9 is welded to the fins 12, which partially cools the fins 12. When the air inside the cabinet 1 circulates into the front chamber 10, it flows through the fins 12 between the first slot 7 and the second slot 8. The fins 12 absorb the heat in the flowing air, so that the cooled air circulates back into the cabinet 1, completing the heat dissipation inside the cabinet 1.
[0025] The airflow replacement chamber 6 has several ventilation slots 15 on the outer wall facing the rear chamber 11. A symmetrically arranged air intake fan 16 and air outlet fan 17 are installed inside the rear chamber 11. The air intake fan 16 and air outlet fan 17 are attached to the inner wall of the rear chamber 11 inside the ventilation slots 15.
[0026] The intake fan 16 and the exhaust fan 17 work together to expel the heat from the rear chamber 11 outside the cabinet through the ventilation slot 15, thus achieving active heat dissipation.
[0027] Based on the above, the cabinet 1 combines forced air cooling (fins 12 + airflow fan 13) and semiconductor cooling technology. The dual heat dissipation mechanism significantly improves cooling efficiency and adapts to high-temperature outdoor environments. The design of the partition 2 and the airflow replacement chamber 6 optimizes the internal space, manages the energy storage equipment and heat dissipation system in separate zones, and has a reasonable layout that saves space.
[0028] Furthermore, a cabinet door 18 is installed inside the cabinet body 1, and a sealing ring 19 is set on the cabinet door 18 for sealing. After the cabinet door 18 is closed, a relatively sealed environment is formed between the inside of the cabinet body 1 and the airflow replacement chamber 6, and closed-loop air circulation is carried out. Closed-loop air circulation reduces the entry of external dust and extends the service life of the equipment; the semiconductor cooling chip 14 precisely controls the temperature, and the energy consumption is lower than that of traditional compressor cooling.
[0029] The vacuum chamber heat spreader 9 has excellent heat dissipation performance, avoiding local overheating. The fan and ventilation slot 15 work together to ensure that the heat in the rear chamber 11 is quickly discharged, and the system operates stably.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
