Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to an energy storage container. Background Technology

[0002] With the large-scale application of new energy power generation, electrochemical energy storage has been widely promoted. Energy storage containers have attracted much attention due to their high degree of modularity, convenient transportation, and easy installation. Energy storage containers can effectively solve the problems of power storage and supply.

[0003] In related technologies, energy storage containers are equipped with liquid chillers to address the heat dissipation problem of their internal battery packs. The high-temperature liquid in the chiller, after absorbing heat, then exchanges heat with the outside air to dissipate heat from the liquid within the chiller. To improve the overall space utilization of the energy storage container, the liquid chiller is installed at one end, and the air inlet and outlet are located at the same end. This structure of the energy storage container easily leads to cross-contamination between hot and cold air; that is, the high-temperature air, after absorbing heat, is immediately drawn back into the inlet after being discharged from the outlet, thus affecting the heat exchange efficiency of the liquid chiller. Utility Model Content

[0004] The purpose of this invention is to propose an energy storage container that can prevent cross-contamination and improve the heat exchange efficiency of a liquid chiller.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] An energy storage container is provided, comprising an energy storage body and a liquid cooler. The energy storage body is provided with a liquid cooling chamber, and the liquid cooler is installed in the liquid cooling chamber. The liquid cooler is provided with a gas inlet and a gas outlet. The energy storage body is provided with an air inlet communicating with the gas inlet and an air outlet communicating with the gas outlet. The orientation of the air inlet and the orientation of the air outlet form an angle.

[0007] Furthermore, the orientation of the air inlet is perpendicular to the orientation of the air outlet.

[0008] Furthermore, the energy storage body includes a housing and an air guide shroud. The liquid-cooled chamber is disposed inside the housing. The air outlet is disposed at one end of the housing along its length. The air guide shroud is disposed at one end of the housing corresponding to the air outlet. The air guide shroud is connected to the liquid-cooled chamber. The air inlet is disposed on the side of the air guide shroud away from the air outlet.

[0009] Furthermore, the air guide shroud includes a first side and a second side that are perpendicular to each other. The second side is connected to the housing. An airflow channel is provided inside the air guide shroud that runs through the first side and the second side. The airflow channel forms the air inlet at one end near the first side.

[0010] Furthermore, the air guide cover also includes a support plate, and multiple support plates are spaced apart in the airflow channel, with the support plates connected and fixed to the housing.

[0011] Furthermore, the air guide cover is connected and fixed to the housing by fasteners.

[0012] Furthermore, the surface of the air guide cover is covered with a heat insulation layer.

[0013] Furthermore, the air outlet is flush with the gas outlet.

[0014] Furthermore, the air inlet and the air outlet are arranged in a horizontal direction.

[0015] Furthermore, the air outlet and / or the air inlet are provided with louvers.

[0016] The beneficial effects of this invention are as follows: By setting the air inlet and air outlet at an angle, i.e., the air inlet and air outlet face different directions, the high-temperature air discharged from the air outlet is prevented from immediately entering the air inlet, thus avoiding cross-contamination between the air inlet and air outlet. Since the air temperature entering the air inlet is relatively low, it helps to improve the heat exchange efficiency of the liquid chiller. Attached Figure Description

Detailed Implementation

[0024] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1 to 4 As shown, this embodiment provides an energy storage container, including an energy storage body 1 and a liquid chiller 2. The energy storage body 1 is the main part of the energy storage container, used for storing electrical energy, and contains several battery packs. A liquid cooling chamber 12 is provided inside the energy storage body 1, and the liquid chiller 2 is installed inside the liquid cooling chamber 12. The liquid chiller 2 cools the battery packs in the energy storage body 1 through liquid cooling. The liquid chiller 2 is provided with a liquid inlet 23 and a liquid outlet 24, which are connected to the liquid cooling plate inside the energy storage body 1 via pipes. The liquid chiller 2 is provided with a gas inlet 21 and a gas outlet 22 for air circulation. The energy storage body 1 is provided with an air inlet 14 and an air outlet 15, which are connected to the gas inlet 21, allowing external air to enter the liquid chiller 2 sequentially through the air inlet 14 and the gas inlet 21. The air outlet 15 is connected to the gas outlet 22 so that the air inside the liquid cooler 2 can be discharged to the outside through the gas outlet 22 and the air outlet 15 in sequence. The orientation of the air inlet 14 and the orientation of the air outlet 15 form an angle.

[0026] Understandably, the liquid chiller 2 contains a liquid cooling medium that circulates between the energy storage unit 1 and the liquid chiller 2. After absorbing heat from the energy storage unit 1, the liquid cooling medium returns to the liquid chiller 2. Low-temperature external air enters the liquid chiller 2 through the air inlet 14 and exchanges heat with the high-temperature liquid cooling medium inside. The low-temperature air absorbs heat from the liquid cooling medium to cool it. The high-temperature air, having absorbed heat, is then discharged to the outside through the air outlet 15. Because the air inlet 14 and the air outlet 15 are oriented at an angle (i.e., the air inlet 14 and the air outlet 15 face different directions), high-temperature air discharged from the air outlet 15 is prevented from immediately entering the air inlet 14, thus avoiding cross-contamination between the air inlet 14 and the air outlet 15. The lower temperature of the air entering the air inlet 14 helps improve the heat exchange efficiency of the liquid chiller 2.

[0027] Specifically, the orientation of the air inlet 14 is perpendicular to the orientation of the air outlet 15. This structure allows the corresponding areas of the air outlet 15 and the corresponding areas of the air inlet 14 to be far apart, avoiding cross-contamination. In this embodiment, the orientation of the air inlet 14 is parallel to the width direction of the energy storage body 1 (Y direction in the figure), and the orientation of the air outlet 15 is parallel to the length direction of the energy storage body 1 (X direction in the figure). The high-temperature air that has absorbed heat in the liquid chiller 2 is discharged from the air outlet 15, and the high-temperature air accumulates on one side of the length direction of the energy storage body 1. The air inlet 14 draws in low-temperature air from one side of the width direction of the energy storage body 1, which can prevent the high-temperature air discharged from the air outlet 15 from being quickly drawn into the liquid chiller 2.

[0028] Specifically, the energy storage unit 1 includes a housing 11 and an air guide shroud 13. The housing 11 has a rectangular frame structure, and the battery pack is installed inside the housing 11. A liquid-cooled chamber 12 is located at one end of the housing 11 along its length (X direction in the figure), and an air outlet 15 is located on the end face of the housing 11, communicating with the liquid-cooled chamber 12. The air guide shroud 13 serves to guide the airflow, limiting the flow direction of external air into the liquid-cooled chamber 12. The air guide shroud 13 is located at the end of the housing 11 corresponding to the air outlet 15, that is, the air guide shroud 13 and the air outlet 15 are located at the same end of the housing 11 along its length. An air inlet 14 is located on the air guide shroud 13, communicating with the liquid-cooled chamber 12. The air inlet 14 is located on the side of the air guide shroud 13 away from the air outlet 15. The liquid cooling chamber 12 is larger than the liquid chiller 2, allowing the extra space in the liquid cooling chamber 12 to accommodate air. The liquid chiller 2 is installed inside the liquid cooling chamber 12, and the gas inlet 21 on the liquid chiller 2 is connected to the liquid cooling chamber 12. During cooling, external air flows sequentially through the air guide shroud 13 and the liquid cooling chamber 12, and enters the liquid chiller 2 through the gas inlet 21. The gas outlet 22 on the liquid chiller 2 faces the air outlet 15, and the gas outlet 22 is flush with the air outlet 15. This structure prevents the high-temperature air after heat exchange inside the liquid chiller 2 from entering the liquid cooling chamber 12, and instead discharges it to the outside simultaneously through the gas outlet 22 and the air outlet 15. Of course, in other embodiments, the gas outlet 22 can also be located inside the liquid cooling chamber 12, with corresponding channels for discharging high-temperature air. Correspondingly, the high-temperature air after heat exchange inside the liquid chiller 2 flows sequentially through the gas outlet 22, the liquid cooling chamber 12, and the air outlet 15 and is discharged to the outside.

[0029] Specifically, the air guide shroud 13 includes a first mounting frame 131, a second mounting frame 132, an arc-shaped plate 133, and two end plates 134. The air guide shroud 13 has a first side and a second side, which are connected and perpendicular to each other. The second side of the air guide shroud 13 is connected to the housing 11, and an air inlet 14 is provided on the first side of the air guide shroud 13. An airflow channel 130 for air circulation is provided inside the air guide shroud 13, with both ends of the airflow channel 130 penetrating the first and second sides respectively. The air inlet 14 is formed at the end of the airflow channel 130 closest to the first side. It can be understood that the air inlet 14 and the air outlet 15 are located at the same end of the energy storage body 1, and the air guide shroud 13 serves to block low-temperature air from high-temperature air. Under the blocking effect of the air guide shroud 13, the air inlet 14 and the air outlet 15 can face different directions. The first mounting frame 131 is located on the first side, and the second mounting frame 132 is located on the second side. The curved plate 133 has a bending angle of 90°, and its two ends along the bending direction are connected to the first mounting frame 131 and the second mounting frame 132, respectively. End plates 134 are provided at both ends of the curved plate 133 along its length, and the sides of the end plates 134 facing away from the curved plate 133 are connected to the first mounting frame 131 and the second mounting frame 132. This structure forms an airflow channel 130 between the first mounting frame 131, the second mounting frame 132, the curved plate 133, and the two end plates 134.

[0030] Specifically, the air guide shroud 13 is connected and fixed to the housing 11 by fasteners. The fasteners are existing screws, bolts, or rivets, etc. Correspondingly, the second mounting frame 132 is provided with mounting holes for fasteners to pass through, so that the air guide shroud 13 is connected and fixed to the housing 11 through the second mounting frame 132.

[0031] Specifically, to improve the overall structural strength of the air guide shroud 13, the air guide shroud 13 also includes a support plate 135. Multiple support plates 135 are spaced apart inside the airflow channel 130. One side of the support plate 135 is connected and fixed to the inner wall of the airflow channel 130, and the other side is connected and fixed to the housing 11.

[0032] Specifically, the surface of the air guide shroud 13 is covered with a heat insulation layer. Since the air guide shroud 13 and the air outlet 15 are located at the same end of the energy storage body 1, the high-temperature air discharged from the air outlet 15 will heat the air guide shroud 13. By providing a heat insulation layer on the air guide shroud 13, the high-temperature air discharged can be prevented from heating the low-temperature air inside the air guide shroud 13, thereby improving the heat exchange efficiency of the liquid cooler 2. Of course, in other embodiments, the air guide shroud 13 can also be made directly using heat insulation material to improve the heat insulation performance of the air guide shroud 13.

[0033] Specifically, the air inlet 14 and air outlet 15 are arranged horizontally. The length of the air guide shroud 13 extends vertically, dividing the area at one end of the energy storage body 1 into two parts horizontally. Air at different temperatures has different densities, and air mixes more easily in the vertical direction. By arranging the air inlet 14 and air outlet 15 horizontally, the corresponding areas of the air inlet 14 and the corresponding areas of the air outlet 15 are spaced apart horizontally, reducing the probability of air mixing between the two areas.

[0034] Specifically, refer to Figure 2 and Figure 5 As shown, the energy storage container also includes louvers 3. Louvers 3 are existing technology and serve a rainproof function. Louvers 3 are provided on both the air outlet 15 and the air inlet 14 to prevent rainwater from entering the liquid cooler 2 and the air guide shroud 13. Of course, in some embodiments, depending on actual rainproof requirements, louvers 3 may be provided only on the air outlet 15 or only on the air inlet 14. A flange 31 is provided on one side of the louvers 3 for installation. The flange 31 is fixed to the first mounting frame 131 by fasteners, and the flange 31 is also fixed to the container body 11 by fasteners.

[0035] It should be noted that this energy storage container has two cooling systems. The first cooling system is a liquid cooling system between the liquid chiller 2 and the battery pack in the energy storage body 1. The liquid cooling medium circulates between the liquid chiller 2 and the battery pack, cooling the battery pack. The second cooling system is an air cooling system consisting of the liquid chiller 2 and external air. Low-temperature external air enters the liquid cooling chamber 12 sequentially through the air inlet 14, and then enters the liquid chiller 2 through the gas inlet 21. The low-temperature air absorbs heat from the liquid cooling medium in the liquid chiller 2, and the heated air is simultaneously discharged through the gas outlet 22 and the air outlet 15. With the operation of these two cooling systems, the heat inside the energy storage body 1 is ultimately discharged into the external air, effectively cooling the entire energy storage container.

[0036] The beneficial effects of this embodiment are as follows: By setting the orientation of the air inlet 14 and the air outlet 15 at an angle, that is, the air inlet 14 and the air outlet 15 face different directions, the high-temperature air discharged from the air outlet 15 is prevented from immediately entering the air inlet 14, thereby preventing cross-contamination between the air inlet 14 and the air outlet 15. Since the air temperature entering the air inlet 14 is relatively low, it is beneficial to improve the heat exchange efficiency of the liquid cooler 2.

[0037] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
