Description

Technical Field

[0001] This utility model relates to the field of liquid-cooled energy storage container technology, and particularly to liquid-cooled energy storage containers. Background Technology

[0002] As the global energy transition accelerates, the penetration rate of renewable energy sources such as solar and wind power continues to increase. However, these energy sources are intermittent and fluctuate, requiring the support of energy storage systems to achieve "smooth output" and "peak shaving and valley filling". As a core device for high-power, high-density energy storage, liquid-cooled energy storage containers have become the mainstream choice for grid-level energy storage, data center backup power, and industrial park microgrids due to their integrated design, efficient heat dissipation capabilities, and strong environmental adaptability.

[0003] The applicant discovered a Chinese patent for a "liquid-cooled energy storage container" with publication number CN217457225U. This patent primarily utilizes a heat dissipation mechanism. During internal cooling of the container, the output shaft of a cooling motor drives fan blades to rotate. The air generated by the fan blades cools the water tank. The cooled water is then delivered through a water pipe into the compartment between the partition and the container body. The water is kept horizontal at both ends and is injected into the entire container, thus cooling the container through liquid cooling. This combines air cooling and liquid cooling, using a circulation method to ensure a moderate internal temperature while minimizing the power consumption required for cooling, effectively improving the container's heat dissipation performance. However, this patent does not allow for the collection and orderly discharge of condensate generated during the cooling process while the coolant circulates at a high flow rate inside the cooling tank. In actual use, long-term condensate retention can lead to increased humidity inside the container, accelerating the corrosion of metal components and shortening the lifespan of the energy storage equipment. Therefore, we propose a liquid-cooled energy storage container. Utility Model Content

[0004] The purpose of this invention is to provide a liquid-cooled energy storage container to solve the problem mentioned in the background art that the coolant cannot circulate at a high flow rate inside the cooling box while simultaneously collecting and orderly discharging the condensate generated during the cooling process. In actual use, the long-term retention of condensate will lead to increased humidity inside the box, thereby accelerating the corrosion of metal parts and shortening the service life of the energy storage equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a liquid-cooled energy storage container, including a container body and a top cover, wherein a liquid-cooled circulation assembly is provided inside and on the back of the container body, the liquid-cooled circulation assembly including an output pump, a fixed block, a collection frame and a control valve, the output pump is connected to a circulation pipe through an output pipe, the circulation pipe is connected to an input pump through a connecting pipe, the input pump is connected to a coolant tank through a return pipe, and a liquid guide pipe is fixedly connected to the input end of the output pump, the end of the liquid guide pipe away from the output pump is fixedly connected to the inside of the coolant tank.

[0006] As a preferred embodiment, the output pump is fixedly installed on the top left side of the coolant tank, one end of the output pipe is fixedly connected to the output end of the output pump, the other end of the output pipe is fixedly connected to the inside of the circulation pipe, and one end of the connecting pipe is fixedly connected to the inside of the circulation pipe.

[0007] As a preferred embodiment, the other end of the connecting pipe is fixedly connected to the input end of the input pump, the input pump is fixedly installed on the top right side of the coolant tank, one end of the return pipe is fixedly connected to the output end of the input pump, and the other end of the return pipe is fixedly connected to the inside of the coolant tank.

[0008] As a preferred embodiment, the coolant tank is located on the rear side of the tank body, the inner wall of the fixing block is fixedly connected to the outer wall of the circulation pipe, the surface of the fixing block is fixedly connected to the inner wall of the tank body, an inclined water collection trough is provided on the inner bottom wall of the tank body, the collection frame is fixedly connected to the lower right outer wall of the tank body, and the control valve is fixedly installed on the right outer wall of the collection frame.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. With the liquid cooling circulation component, the operator can start the output pump to deliver the coolant from the coolant tank to the circulation pipe, allowing it to fully contact the heat-generating components such as the battery pack inside the tank and absorb the operating heat. Then, the input pump is started to return the coolant from the circulation pipe to the coolant tank. This allows the heated coolant to dissipate heat and prevents heat retention. This ensures high-speed circulation of the coolant, improves the heat exchange efficiency per unit time, and controls the fluctuation of the battery pack's operating temperature. At the same time, the condensate generated inside the tank can be collected in a tilted water collection tank to collect condensate or accidental leaks on the surface of the circulation pipe. The condensate is then guided by gravity to the collection box on the right. The operator can control the valve to drain the liquid periodically to prevent the accumulation of liquid in the tank and the risk of electrical short circuits.

[0013] 2. With the air-cooling components in place, when the battery pack inside the enclosure operates at a low temperature, only air cooling is used to reduce power consumption. The staff can start the fan and introduce cold air from outside into the enclosure through the perforated slots to accelerate airflow. The dustproof plate's filter structure intercepts dust particles in the air, and the fixed frame's closed design prevents foreign objects from entering from the side, ensuring the cleanliness of the fan and the inside of the enclosure.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see the appendix Figure 1 - Appendix Figure 4 The liquid-cooled energy storage container includes a container body 1 and a top cover 2. A liquid-cooled circulation assembly 3 is installed inside the container body 1 and on its back. The liquid-cooled circulation assembly 3 includes an output pump 301, a fixing block 309, a collection frame 311, and a control valve 312. The output pump 301 is connected to a circulation pipe 303 through an output pipe 302. The circulation pipe 303 is connected to an input pump 305 through a connecting pipe 304. The input pump 305 is connected to a coolant tank 307 through a return pipe 306. A liquid guide pipe 308 is fixedly connected to the input end of the output pump 301. The end of the liquid guide pipe 308 away from the output pump 301 is fixedly connected to the inside of the coolant tank 307.

[0023] The liquid guide pipe 308 can introduce the liquid from the coolant tank 307 into the interior of the output pump 301. The top of the coolant tank 307 is fixedly installed with an inlet pipe, through which the operator injects coolant into the interior of the coolant tank 307.

[0024] The output pump 301 is fixedly installed on the top left side of the coolant tank 307. One end of the output pipe 302 is fixedly connected to the output end of the output pump 301, and the other end of the output pipe 302 is fixedly connected to the inside of the circulation pipe 303. One end of the connecting pipe 304 is fixedly connected to the inside of the circulation pipe 303, and the other end of the connecting pipe 304 is fixedly connected to the input end of the input pump 305. The input pump 305 is fixedly installed on the top right side of the coolant tank 307. One end of the return pipe 306 is fixedly connected to the input pump. The output end of 305 and the other end of the return pipe 306 are fixedly connected to the inside of the coolant tank 307. The coolant tank 307 is located on the rear side of the tank body 1. The inner wall of the fixing block 309 is fixedly connected to the outer wall of the circulation pipe 303. The surface of the fixing block 309 is fixedly connected to the inner wall of the tank body 1. An inclined water collection trough 310 is provided on the inner bottom wall of the tank body 1. The collection frame 311 is fixedly connected to the lower right outer wall of the tank body 1. The control valve 312 is fixedly installed on the right outer wall of the collection frame 311.

[0025] The inclined water collection tank 310 adopts a slope design with the left side higher than the right side. When condensation occurs on the surface of the circulation pipe 303 and the inner wall of the tank 1, the condensation flows to the right side along the inclined water collection tank 310 due to gravity and eventually collects in the collection frame 311. The operator can open the control valve 312 to discharge the condensation in the collection frame 311 out of the tank 1.

[0026] Specifically, through the liquid cooling circulation component 3, the operator starts the output pump 301 to deliver the coolant in the coolant tank 307 to the circulation pipe 303, allowing it to contact the heat-generating components such as the battery pack inside the housing 1 to absorb heat. Then, the input pump 305 is started to return the coolant in the circulation pipe 303 to the coolant tank 307 for heat dissipation, preventing heat from accumulating. This process ensures high-speed circulation of the coolant, improves the heat exchange efficiency per unit time, and controls the fluctuation of the battery pack's operating temperature. At the same time, the condensate generated inside the housing 1 is collected by the inclined water collection tank 310 to collect the condensate or leaked liquid on the surface of the circulation pipe 303. The liquid is then guided by gravity to the collection frame 311 on the right side. The operator discharges the liquid periodically by controlling the valve 312 to prevent the accumulation of liquid in the housing 1 from causing the risk of electrical short circuit.

[0027] Please see the appendix Figure 1 Appendix Figure 5 and appendix Figure 6 The upper cover 2 has an air-cooling component 4 inside and on top. The air-cooling component 4 includes a support frame 402. The top of the upper cover 2 has a hollow groove 401. The outer wall of the support frame 402 is fixedly connected to the inner wall of the hollow groove 401. A fan 403 is fixedly installed on the upper surface of the support frame 402. A fixing frame 404 is fixedly installed on the top of the upper cover 2 and is located directly above the fan 403. A dustproof plate 405 is fixedly installed on the inner wall of the top of the fixing frame 404.

[0028] The dustproof plate 405 is installed on the top inner wall of the fixed frame 404. The surface has dense pores, which allow air to pass through while filtering dust, particles and other impurities in the air, preventing them from entering the box 1 and contaminating the energy storage equipment or affecting the operation of the liquid cooling system.

[0029] Specifically, by using the air-cooling component 4, when the operating temperature of the battery pack inside the housing 1 is low, only air cooling is used to reduce power consumption. When the staff starts the fan 403, external cold air is introduced into the housing 1 through the hollow slot 401 to accelerate airflow. The filter structure of the dustproof plate 405 intercepts dust particles in the air. The fixed frame 404 prevents foreign objects from entering from the side through the closed design, ensuring the cleanliness of the fan 403 and the inside of the housing 1.

[0030] Working principle of this utility model: This utility model is a liquid-cooled energy storage container. First, the operator starts the output pump 301, and the coolant in the coolant tank 307 is drawn through the liquid guide pipe 308 and transported to the circulation pipe 303 through the output pipe 302. The circulation pipe 303 is distributed inside and on the back of the container 1, and is in close contact with the heat-generating elements such as the battery pack. The coolant absorbs the heat generated by its operation and its temperature rises. Then, the operator starts the input pump 305, and draws the heated coolant through the connecting pipe 304 and sends it back to the coolant tank 307 through the return pipe 306. Heat dissipation is completed inside the container, and the coolant enters the next cycle after cooling down. During the liquid cooling cycle, the condensate generated on the surface of the circulation pipe 303 and the inner wall of the container 1 flows along the water collection tank under the action of gravity due to the slope design of the inclined water collection tank 310, which is higher on the left and lower on the right. On the right side, the condensate eventually collects in the collection box 311. The operator can open the control valve 312 to drain the condensate from the collection box 311 out of the box 1, preventing the accumulation of liquid in the box 1 from causing electrical short circuits and other risks. Then, when the operating temperature of the battery pack inside the box 1 is at a low level, in order to reduce energy consumption, only the air-cooling component 4 is used. The operator starts the fan 403, and the cold air outside is introduced into the box 1 through the hollow groove 401 on the top of the cover 2. The fan 403 accelerates the airflow and carries away the small amount of heat emitted by the battery pack. During this process, the dense pores on the surface of the dustproof plate 405 play a filtering role, intercepting dust, particles and other impurities in the air. The fixed frame 404 has a closed design to prevent foreign objects from entering from the side, which together ensures the cleanliness of the fan 403 and the inside of the box 1, and ensures the stable operation of the air-cooling system.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
