Description

Technical Field

[0001] This utility model relates to the field of energy storage technology, and in particular to energy storage systems and cascaded energy storage system groups. Background Technology

[0002] An energy storage system is a defined area of ​​objects or space used to determine the research object when analyzing the energy storage process. It includes the input and output of energy and matter, energy conversion and storage devices. Simply put, an energy storage system refers to a complete set of equipment and technologies capable of storing energy and releasing it when needed. Its core function is to address the time imbalance between electricity production and consumption, much like a large-capacity "power bank" or "reservoir" for the power grid.

[0003] Energy storage systems are commonly used in power generation equipment such as solar and wind power, which convert solar and kinetic energy into chemical energy in battery banks for storage. During energy storage and release, the conversion and conduction of energy generate heat. This heat exists within the energy storage system equipment, easily causing heat buildup. As the heat increases, the energy storage system equipment will reduce its power output to protect itself from damage, but this decrease in operating efficiency also reduces the efficiency of energy storage and release. Therefore, we propose the concept of energy storage systems and cascaded energy storage system groups. Utility Model Content

There is a gap between the first baffle and the first heat exchanger tube, and the first baffle is fixed to the inner wall of the chassis by a fixing bracket.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example

[0026] Reference Figures 1-6 The energy storage system and cascaded energy storage system group include a chassis 1, an energy storage component 5 is installed inside the chassis 1, and the energy storage component 5 is installed on a mounting rack 6.

[0027] An opening 2 is provided on one side of the chassis 1. A sealing door 3 is detachably installed on the opening 2. Several fans 4 are installed on the sealing door 3 at intervals, which can draw air from outside the chassis 1 into the chassis 1. In actual use, one side of the sealing door 3 is hinged to one side of the opening 2, and the other side of the sealing door 3 is fixed to the chassis 1 by a latch.

[0028] A second baffle 18 is provided on the side of the sealed door 3 away from the chassis 1. The corner of the second baffle 18 is fixed to the sealed door 3 by a bracket. It can guide the air entering the fan 4, so that the air can only flow to the fan 4 through the gap between the second baffle 18 and the sealed door 3. This reduces the flow of dust to the fan 4 and also shields the fan 4 to prevent the staff from accidentally touching the fan 4.

[0029] Inside the chassis 1, on the side away from the opening 2, there is a first heat spreader 7 arranged in multiple S-shaped bends. On the outside of the chassis 1, there is a second heat spreader 8 arranged in multiple S-shaped bends. One end of the second heat spreader 8 passes through the chassis 1 and is connected to one end of the first heat spreader 7. The other end of the second heat spreader 8 is connected to the coolant tank 9, which is fixed to the outer wall of the chassis 1. A delivery pump 10 is installed on one side of the coolant tank 9. The inlet of the delivery pump 10 is placed inside the coolant tank 9 and connected to a conduit. The other end of the conduit is placed at the bottom of the coolant tank 9. A delivery pipe 11 is installed at the outlet of the delivery pump 10. The other end of the delivery pipe 11 passes through the chassis 1 and is connected to the other end of the first heat spreader 7, allowing the coolant in the coolant tank 9 to circulate between the first heat spreader 7 and the second heat spreader 8. In this way, the heat energy in the chassis 1 will transfer heat to the coolant in the first heat spreader 7. Under the flow of the coolant, the absorbed coolant will be sent back to the coolant tank 9.

[0030] Furthermore, several cooling chip assemblies 12 are installed on one side of the coolant tank 9. Each cooling chip assembly 12 includes a cooling chip, which is installed on the side of the coolant tank 9. The cold end of the cooling chip penetrates the coolant tank 9 and is placed inside the coolant tank 9, while the hot end of the cooling chip is placed outside the coolant tank 9. Heat dissipation fins are installed on the hot end of the cooling chip, and a cooling fan is installed on the other side of the fins to accelerate the airflow around the fins. This cools the coolant flowing back into the coolant tank 9, ensuring that the coolant entering the first heat exchanger 7 is always at a low temperature. This allows for better absorption of heat energy inside the chassis 1 and effective cooling of the chassis 1.

[0031] It should be noted that the bends of the first heat spreader 7 and the second heating pipe 8 are both right angles, which can increase the contact area between the heat spreader and the air, improve the heat absorption efficiency of the coolant inside the chassis 1, and the heat dissipation efficiency of the coolant outside the chassis 1.

[0032] A first baffle 13 is provided inside the chassis 1 near the first heat spreader 7. A gap is left between the first baffle 13 and the first heat spreader 7, and the first baffle 13 is fixed to the inner wall of the chassis 1 by a fixing bracket 14. Multiple spaced strip grooves 15 are formed on the first baffle 13, corresponding to the gaps between adjacent tubes of the first heat spreader 7. Arc-shaped plates 16 are provided on both sides of the strip grooves 15. One side of the arc-shaped plate 16 is fixed to the first baffle 13, and the other side of the arc-shaped plate 16 faces the gaps between adjacent tubes of the first heat spreader 7. The convex surface of the arc-shaped plate 16 faces the strip groove 15. After the fan 4 blows air from outside the chassis 1 into the chassis 1, the air absorbs and stores energy. The heat from component 5 flows toward the first heat spreader 7, and then the air comes into contact with the first baffle 13. At this time, the air flows into the strip groove 15 under the guidance of the first baffle 13, and is concentrated in the gap between the tubes of the first heat spreader 7 under the guidance of the arc plate 16. This allows the hot air to concentrate and contact the first heat spreader 7. Furthermore, the hot air can flow repeatedly in the first heat spreader 7 under the obstruction and restriction between the first baffle 13 and the inner wall of the chassis 1, thereby improving the contact between the hot air and the first heat spreader 7. In addition, the first baffle 13 and the arc plate 16 are both heat spreaders, which can exchange heat energy with the hot air, thereby further improving the contact between the heat inside the chassis 1 and the first heat spreader 7.

[0033] Furthermore, an arc-shaped cut surface 17 is provided on the other side of the strip groove 15 away from the arc plate 16 to guide the air that comes into contact with the first baffle 13, so that the air flows to the strip groove 15 more quickly.

[0034] A first control box 19 is installed on the side of the second baffle 18 away from the sealing door 3. The first control box 19 contains a controller, which is connected to the fan 4, energy storage component 5, delivery pump 10, and cooling chip assembly 12 via wires. In actual use, the controller is one of a PLC logic controller, a control motherboard, or a control host. A temperature sensor is installed on the inner wall of the chassis 1 and is connected to the controller via wires to monitor the temperature inside the chassis 1 so as to intelligently regulate the rotation speed of the fan 4 and the output power of the delivery pump 10.

[0035] This utility model also includes a cascaded energy storage system group, including a support frame 20, multiple chassis 1 are arranged at intervals on the support frame 20, and multiple controllers are connected in series through energy storage converters to realize the assembly and use of multiple energy storage systems, and to construct a larger energy storage system in a modular way.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
