[0001] This utility model belongs to the field of energy storage battery technology, specifically relating to a modular structure for energy storage batteries. Background Technology

[0002] Energy storage batteries can convert chemical energy into electrical energy, providing stable power supply over a long period of time. Modular structures, on the other hand, are installation structures that facilitate the assembly of multiple energy storage batteries to save space. They can save space occupied by energy storage batteries and can easily combine multiple battery modules according to the required energy capacity, output power, and available installation space.

[0003] Chinese patent document CN221508387U discloses a modular structure for energy storage batteries. By setting a water tank outside the main body of the battery box, the water tank can cool the cooling box while the cooling box cools the battery module.

[0004] However, in the existing technology, although the modular structure has the function of cooling the battery, the way the components that perform this function are arranged makes it difficult to assemble multiple modular structures on a large scale, and there is a lack of effective measures to control the rise of coolant temperature. Therefore, a modular structure for energy storage batteries is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a modular structure for energy storage batteries.

[0006] The technical solution adopted in this utility model is as follows:

[0007] A modular structure for energy storage batteries includes a loading assembly that allows multiple modular structures to be easily spliced ​​and assembled. The loading assembly contains an energy storage component that can store electrical energy for later use. The loading assembly also contains a heat dissipation component that allows the internal temperature of the modular structure to be easily controlled.

[0008] The loading assembly includes a frame, a base plate fixedly connected to the bottom of the frame, a fastening frame fixedly connected to one side and the rear of the frame, and an embedding frame fixedly connected to the other side and the front of the frame.

[0009] The energy storage component includes an energy storage battery body that is fixedly mounted on the base plate;

[0010] The heat dissipation component includes a storage component that can store a certain amount of coolant and effectively control its temperature rise, a filter component that can prevent external debris from flowing with the air within this modular structure, a cooling component that can fully dissipate heat from the energy storage battery body, and a transport component that can prevent large temperature differences in the coolant at different points within the heat dissipation component.

[0011] The storage unit includes two liquid storage tanks fixedly installed inside the frame, with a cover fixedly connected to the top of each liquid storage tank, and an exhaust fan fixedly installed between the two liquid storage tanks.

[0012] Preferably, the storage component further includes an air inlet groove integrally formed on the side of the liquid storage tank near another liquid storage tank, and an exhaust groove integrally formed on the side of the liquid storage tank where the air inlet groove is provided.

[0013] Preferably, the filter element includes an air inlet baffle fixedly connected to both sides of the liquid storage tank, and an exhaust baffle fixedly connected to the top of the liquid storage tank.

[0014] Preferably, the cooling component includes a distribution box fixedly connected to the side of the liquid storage tank away from another liquid storage tank, a first connecting pipe fixedly connected between adjacent liquid storage tanks and the distribution box, and a second connecting pipe fixedly connected between two distribution boxes in the same lateral position.

[0015] Preferably, the conveying component includes a pump fixedly installed below the liquid storage tank, and a third connecting pipe is fixedly connected between the liquid storage tank and the pump.

[0016] Preferably, the air inlet slot extends horizontally through the liquid storage tank, and the exhaust slot extends vertically through the air inlet slot.

[0017] Preferably, both the liquid storage tank and the diversion tank are hollow structures.

[0018] The beneficial effects of this utility model are as follows: by facilitating the co-location of the energy storage component and the heat dissipation component inside the loading component, the modular structure has a high degree of integration, so that different modular structures can be quickly assembled by fastening frames and embedding frames of matching lengths; it facilitates the cooling of the liquid storage tank by the operation of the exhaust fan, thereby making the overall temperature rise of the coolant flowing in various parts of the heat dissipation component controllable, so as to continuously cool the energy storage battery body and provide a guarantee for the stable operation of this modular structure.

[0032] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0033] like Figures 1-8 As shown, a modular energy storage battery structure includes a loading component 1 that allows multiple modular structures to be easily spliced ​​and assembled. The loading component 1 contains an energy storage component 2 that can store electrical energy for later use. The loading component 1 also contains a heat dissipation component 3 that allows the internal temperature of the modular structure to be easily controlled.

[0034] In this embodiment: the loading component 1 includes a frame 101, a base plate 102 is fixedly connected to the bottom of the frame 101, a fastening frame 103 is fixedly connected to one side and the rear of the frame 101, an embedding frame 104 is fixedly connected to the other side and the front of the frame 101, and an air inlet 105 is integrally formed on both sides of the frame 101. Screw holes 106 are provided on the embedding frame 104 and the air inlet 105.

[0035] The frame with an opening at the top is formed by the frame 101 and the base plate 102, and the energy storage component 2 and the heat dissipation component 3 are installed. The fastening frame 103 and the embedding frame 104 make it easy to assemble different modular structures. There is a certain gap between the two assembled modular structures so that outside air can enter the air intake slot 304 through the air intake port 105 and the air intake baffle 306. The fastening frame 103 and the embedding frame 104, which belong to the two modular structures, are connected by bolts and other fasteners of the same size through the screw holes 106 to improve the connection effect between the fastening frame 103 and the embedding frame 104.

[0036] In this embodiment: the energy storage component 2 includes an energy storage battery body 201 fixedly installed on the base plate 102, and a pressure strip 202 is fixedly connected above the frame 101;

[0037] The energy storage battery body 201, which can store a certain amount of electricity, serves as the energy storage unit of this modular structure. The pressure strip 202 further improves the fixing effect of the energy storage battery body 201 within the frame composed of the frame 101 and the base plate 102.

[0038] In this embodiment: the heat dissipation assembly 3 includes a storage component that can store a certain amount of coolant and effectively control its temperature rise; a filter component that can prevent external debris from flowing with the air within this modular structure; a cooling component that can fully dissipate heat from the energy storage battery body 201; and a conveying component that can prevent large temperature differences in the coolant at various points within the heat dissipation assembly 3. The storage component includes two liquid storage tanks 301 fixedly installed within the frame 101. A cover 302 is fixedly connected above each liquid storage tank 301. An exhaust fan 303 is fixedly installed between the two liquid storage tanks 301. The storage component also includes an air inlet groove 304 integrally formed on the side of the liquid storage tank 301 closest to the other liquid storage tank 301. The liquid storage tank 301 is provided with... An exhaust groove 305 is integrally formed on the side where the air inlet groove 304 is located. The filter includes an air inlet baffle 306 fixedly connected to both sides of the liquid storage tank 301. An exhaust baffle 307 is fixedly connected above the liquid storage tank 301. The cooling component includes a distribution box 308 fixedly connected to the side of the liquid storage tank 301 away from the other liquid storage tank 301. A first connecting pipe 309 is fixedly connected between adjacent liquid storage tanks 301 and distribution box 308. A second connecting pipe 310 is fixedly connected between two distribution boxes 308 in the same lateral position. The conveying component includes a pump 311 fixedly installed below the liquid storage tank 301. A third connecting pipe 312 is fixedly connected between the liquid storage tank 301 and the pump 311.

[0039] The air inlet groove 304 extends horizontally through the liquid storage tank 301, and the exhaust groove 305 extends vertically through the air inlet groove 304. Both the liquid storage tank 301 and the diversion box 308 are hollow structures.

[0040] A certain amount of coolant is stored in the storage tank 301, providing installation positions for components such as the exhaust fan 303 and the pump 311. The inlet of the storage tank 301 is sealed by the cover 302 to prevent coolant leakage. Removing the cover 302 allows for easy addition of coolant to the storage tank 301 or replacement of the coolant. The operation of the exhaust fan 303, located within the exhaust duct 305, expels air from the exhaust duct 305 to the outside, creating a negative pressure within the exhaust duct 305. This allows outside air to continuously enter the intake duct 304 and then the exhaust duct 305 through the intake baffle 306. 07. To prevent large external impurities from entering the air intake sump 304 or exhaust sump 305, so as to avoid blockage or affect the normal operation of the exhaust fan 303, the various energy storage battery bodies 201 are separated by the distribution box 308. The coolant can flow between adjacent storage tanks 301 and distribution boxes 308 through the first connecting pipe 309. The coolant can flow between distribution boxes 308 connected to different storage tanks 301 through the second connecting pipe 310. By operating the pump 311, the coolant in one of the storage tanks 301 is drawn out along the third connecting pipe 312 connected to it and injected into another storage tank 301 connected to the third connecting pipe 312 along another third connecting pipe 312.

[0041] Working principle: When this energy storage battery modular structure is installed and put into use, if it is necessary to assemble two or more modular structures, the fastening bracket 103 on the modular structure can be inserted into the embedding bracket 104 of the same length in another modular structure, and then the external bolts can be inserted into the screw holes 106 on the connected fastening bracket 103 and the embedding bracket 104, thereby realizing a fast and stable connection between different modular structures.

[0042] To prevent the energy storage battery body 201 from overheating, the exhaust fan 303 and pump 311 can be continuously operated during the use of the modular structure. The exhaust fan 303 allows outside air to continuously enter the exhaust slot 305 through the air inlet 105, the air inlet baffle 306, and the air inlet slot 304, and then be discharged from the exhaust baffle 307. During this process, the continuously flowing air will cool the coolant tank 301, thereby making the temperature rise of the coolant in the coolant tank 301 controllable. On this basis, the operation of the pump 311 allows the coolant in the heat dissipation component 3 to continuously flow in a fixed direction between different coolant tanks 301 and the distribution box 308 connected to the coolant tank 301. This makes the temperature of the coolant tank 301 and the distribution box 308 that can contact the energy storage battery body 201 controllable as a whole, thus facilitating the control of the temperature changes of all energy storage battery bodies 201 and preventing their overheating from affecting the normal use of this modular structure.

[0043] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
