Description

Technical Field

[0001] This application relates to the field of energy storage cabinets, and more particularly to an outdoor energy storage cabinet. Background Technology

[0002] Currently, with the widespread application of energy storage equipment, and in order to reasonably reduce the construction cost of energy storage sites, more and more energy storage and related products need to be centrally deployed in outdoor environments. However, the outdoor temperature is high in summer, and the electrical components inside the outdoor energy storage cabinet will also generate a lot of heat during operation, resulting in a high temperature inside the outdoor energy storage cabinet. In order to maintain the normal operation of the outdoor energy storage cabinet, a heat dissipation device is installed inside the outdoor energy storage cabinet to dissipate the internal heat and maintain the internal temperature of the outdoor energy storage cabinet within a suitable range.

[0003] However, the inventors recognized that outdoor energy storage cabinets have the following drawbacks in actual use: because the internal space of the cabinet is divided into multiple areas, the cold air generated by the heat dissipation device is concentrated in the area near the air outlet of the heat dissipation device. The cold air cannot circulate effectively in the area, resulting in poor cooling effect in other areas and a short service life of electrical components. Utility Model Content

[0004] This application provides one or more embodiments of an outdoor energy storage cabinet to solve or at least partially alleviate the problem of poor cooling effect of heat dissipation devices in related technologies.

[0005] One or more embodiments of this application provide an outdoor energy storage cabinet, employing the following technical solution: An outdoor energy storage cabinet includes: a cabinet body, the cabinet body having an internal accommodating space and several partitions, the partitions dividing the accommodating space into multiple chambers; a cabinet door, the cabinet door being closable and connected to the cabinet body; a temperature control device and electrical devices, the temperature control device being disposed corresponding to the air inlet of the cabinet body to supply air to the accommodating space of the cabinet body, the electrical devices and the temperature control device being distributed in different chambers; an air duct assembly, the air duct assembly having an air inlet, a return air inlet, an air inlet channel, a guide channel, and a return air channel, the air inlet facing the temperature control device, the air inlet channel connecting one side of the air inlet and the guide channel along a first direction, the guide channel connecting the air inlet channel and the return air channel along a second direction, the return air channel connecting the other side of the guide channel and the return air inlet along the first direction, the electrical devices being distributed in the chambers where the guide channel and the return air channel are located.

[0009] In one embodiment, the return air guide plate is inclined in the third direction within the fourth chamber, and the return air duct includes a first return air duct and a second return air duct that are interconnected. The fourth chamber and the second air guide port form the first return air duct, and the fourth chamber and the return air duct form the second return air duct.

[0010] In one embodiment, the return air guide plate includes a first return air plate, a second return air plate, and a third return air plate.

The buffer member is disposed between the transformer and the base body so that the transformer and the base body can elastically abut against each other. The limiting member is disposed on the periphery of the base body to restrict the movement of the base body within the third chamber.

[0014] In one embodiment, the electrical device further includes a fuse disposed within the second return air duct, and the fuse and the return air vent are disposed opposite each other in a third direction.

[0015] Compared with related technologies, one or more embodiments of this application include at least one of the following beneficial technical effects: (1) An air duct assembly is installed inside the cabinet to guide the airflow of the temperature control device, so that the airflow can flow from the air inlet channel into the guide channel and then into the return air channel, thereby improving the airflow efficiency and utilization rate, and thus regulating the temperature inside the cabinet and avoiding excessive local temperature differences inside the cabinet.

[0031] One or more embodiments of this application disclose an outdoor energy storage cabinet 1, with reference to... Figure 1 and Figure 2 The outdoor energy storage cabinet 1 includes: a cabinet body 10, a cabinet door 20, a temperature control device 30, electrical components 40, and an air duct assembly 100. The cabinet body 10 has an internal storage space 11 and several partitions 12, which divide the storage space 11 into multiple chambers. The cabinet door 20 is closable and connected to the cabinet body 10. The temperature control device 30 is installed on one side of the cabinet door 20 to supply air to the storage space 11 of the cabinet body 10. The electrical components 40 and the temperature control device 30 are distributed in different chambers. The air duct assembly 100 is provided with an air inlet 115. The air inlet 115 faces the temperature control device 30. The air inlet 115 connects the air inlet 115 and one side of the air guide channel 102 along a first direction. The air guide channel 102 connects the air inlet 115 and the air guide channel 102 along a second direction. The air return channel 103 connects the other side of the air guide channel 102 and the air inlet 116 along the first direction. The electrical device 40 is distributed in the chamber where the air guide channel 102 and the air return channel 103 are located.

[0032] In some embodiments, such as Figure 1 As shown, the cabinet body 10 is rotatably connected to the cabinet door 20. The temperature control device 30 is installed on the cabinet door 20, and the temperature control device 30 sends air into the accommodating space 11 through the air inlet 115, thereby regulating the ambient temperature inside the accommodating space 11. The air inside the accommodating space 11 enters the temperature control device 30 through the return air inlet 116 to complete the gas circulation.

[0033] In some embodiments, such as Figure 2 As shown, the partition 12 divides the accommodating space 11 into multiple chambers for installing electrical devices 40. The air duct assembly 100 includes an air inlet 115, a return air inlet 116, an air inlet channel 101, a guide channel 102, and a return air channel 103. According to... Figure 1It is known that the air inlet 115 and the return air outlet 116 are located on the cabinet 10. The air inlet 115 faces the temperature control device 30, so that the air blown by the temperature control device 30 enters the chamber through the air inlet 115, which improves the utilization rate of the air and prevents the air from overflowing. This makes the temperature control device 30 more efficient in regulating the temperature and avoids the electrical device 40 from overheating and aging.

[0034] Among them, there is a sealing element between the air outlet and the air inlet 115 of the temperature control device 30, which improves the sealing effect between the air outlet and the air inlet 115 and prevents gas from overflowing.

[0035] In some embodiments, the two ends of the air inlet channel 101 are connected to the air inlet 115 and the guide channel 102, respectively, so that the air enters the accommodating space 11 from the air inlet 115 and then flows into the air inlet channel 101 and the guide channel 102, thereby reducing the ambient temperature of the electrical device 40 in the accommodating space 11. The other end of the guide channel 102 is connected to the return air channel 103, so that the air can flow into the return air channel 103 to further regulate the temperature, and the air flows back into the temperature control device 30 through the return air channel 103 to realize the circulation of gas.

[0036] The first direction is the length direction of the cabinet 10, which is the X direction; the second direction is the height direction of the cabinet 10, which is the Z direction; and the third direction is the width direction of the cabinet 10, which is the Y direction.

[0037] To further explain, the temperature control device 30 is implemented as an air conditioner, which delivers cool air into the housing space 11 in summer and hot air into the housing space 11 in winter, and adjusts the internal temperature of the cabinet 10 according to different outdoor temperatures.

[0038] In some embodiments, the outdoor energy storage cabinet 1 is further provided with an air guide assembly 13, which includes an air inlet guide plate 131 and a return air guide plate 132, a first air guide port 133 and a second air guide port 134. The air inlet guide plate 131 adjusts the air direction so that the air flows through the first air guide port 133 into the air guide channel 102, and then flows into the return air channel 103 through the second air guide port 134.

[0039] In some embodiments, such as Figure 2 and Figure 5 As shown, the air inlet guide plate 131 is positioned towards the air inlet 115 to guide the airflow, causing the air to flow along the extension direction of the air inlet guide plate 131 to the first air guide port 133, thereby entering the guide channel 102. This regulates the temperature of the electrical components 40 within the guide channel 102, preventing a large temperature difference between the local area and the ambient temperature caused by direct airflow. The gas continues to flow along the guide channel 102 and passes through the second air guide port 134 into the return air channel 103, eventually returning to the temperature control device 30.

[0040] In some embodiments, the plurality of chambers include: a first chamber 111, a second chamber 112, a third chamber 113, and a fourth chamber 114. The first chamber 111 and the second chamber 112 are interconnected through a first air vent 133. The second chamber 112 and the third chamber 113 are arranged opposite to each other along a second direction and are interconnected to form a flow channel 102. The third chamber 113 and the fourth chamber 114 are interconnected through a second air vent 134.

[0041] like Figure 2 As shown, the storage space 11 is divided into four chambers, which physically separate the electrical components 40 inside the cabinet 10, improving the safety of the outdoor energy storage cabinet 1. The chambers are interconnected, allowing air to circulate between them, forming a three-dimensional air duct. This layered coverage of the electrical components 40 at different heights not only reduces the space occupied by the outdoor energy storage cabinet 1, but also covers the electrical components 40 inside the cabinet 10, resulting in a more significant temperature regulation effect.

[0042] In some embodiments, the air inlet guide plate 131 is inclinedly disposed in the first chamber 111 along the first direction, and the air inlet guide plate 131 and the air inlet 115 are disposed opposite each other along the third direction, and the air inlet guide plate 131, the first chamber 111 and the first air inlet 133 form an air inlet channel 101.

[0043] In some embodiments, such as Figure 2 As shown, the air inlet guide plate 131 is inclinedly disposed in the first chamber 111 and faces the air inlet 115, so that the air flowing into the air inlet 115 can come into contact with the air inlet guide plate 131 to adjust the air direction and form an airflow path with the same direction, thereby blowing towards the first air guide port 133, making the structure of the air inlet channel 101 more reasonable. Compared with the air guide plate installed vertically in the first chamber 111, the inclined air inlet guide plate 131 can reduce airflow impact loss, reduce wind resistance, increase the air intake speed, and enhance the air intake power.

[0044] In some embodiments, the return air guide plate 132 is inclined in the third direction and disposed in the fourth chamber 114. The return air duct 103 includes a first return air duct 1031 and a second return air duct 1032 that are interconnected. The fourth chamber 114 and the second air guide 134 form the first return air duct 1031, and the fourth chamber 114 and the return air duct 116 form the second return air duct 1032.

[0045] Specifically, such as Figure 2As shown, the return air guide plate 132 is inclined along the third direction and installed in the fourth chamber 114 to diffuse the air flowing into the fourth chamber 114 and adjust the air direction. The fourth chamber 114 and the second air guide 134 form the first return air channel 1031, so that the air blows into the fourth chamber 114 and adjusts the temperature of the electrical device 40 inside the fourth chamber 114. The fourth chamber 114 and the return air vent 116 form the second return air channel 1032, so that after the air is conditioned, it returns to the temperature control device 30 through the second return air channel 1032 to complete the gas circulation.

[0046] In some embodiments, the return air guide plate 132 includes a first return air plate 1321, a second return air plate 1322, and a third return air plate 1323. The first return air plate 1321, the second return air plate 1322, and the third return air plate 1323 are spaced apart in the fourth chamber 114. An included angle α exists between the return air guide plate 132 and the partition plate 12, and the included angle α satisfies: 30°≤α≤90° In some embodiments, such as Figure 4 As shown, where Figure 4 yes Figure 3 In the cross-sectional view along the AA direction, the return air guide plate 132 includes a first return air plate 1321, a second return air plate 1322, and a third return air plate 1323 arranged at intervals. The distance between the three plates can be the same or different. The first return air plate 1321, the second return air plate 1322, and the third return air plate 1323 are parallel to each other and are inclined along the third direction at an angle of α. They play a role in uniformly distributing air in the first direction, forming a planar airflow, expanding the range of airflow, and effectively avoiding the problem of large differences between local and overall temperatures.

[0047] like Figure 4 As shown, there is an included angle α between the return air guide plate 132 and the partition plate 12. The included angle α is in the range of 30°≤α≤90°, preferably 30°, 35°, 40°, 45°, 50°, 55°, 70°, 73°, 75°, 76°, and 80°.

[0048] In some embodiments, the electrical device 40 includes a battery component 44, which is installed within the second chamber 112 and is disposed adjacent to the first air vent 133, such as... Figure 2As shown, the first air vent 133 directly delivers airflow to the battery component 44. In summer, when the external temperature is high, the battery component 44 will also generate a lot of heat during operation. Therefore, the temperature control device 30 delivers cold air into the cabinet 10 to reduce the temperature inside the cabinet 10. The cold air blows onto the battery component 44, quickly reducing the heat around the battery component 44, thereby reducing the surface temperature of the battery component 44 and preventing the battery component 44 from overheating. In winter, when the external temperature is low, the temperature control device 30 delivers hot air into the housing space 11 to regulate the temperature around the battery component 44, thereby increasing the temperature of the battery component 44 and preventing the battery component 44 from being unable to start due to low temperature.

[0049] In some embodiments, the electrical device 40 further includes a transformer 41, which is mounted in the third chamber 113 via a base 42, such as Figure 7 As shown, transformer 41 is installed in the third chamber 113 via base 42. Transformer 41 is a high-voltage, high-current device, and is isolated from battery component 44, making the outdoor energy storage cabinet 1 safer during use. Figure 8 As shown, the transformer 41 and the base 42 are rigidly connected by bolts to prevent the transformer 41 from being displaced due to vibration during transportation, thereby improving the stability of the transformer 41. In addition, the base 42 has an opening, so when installing the transformer 41, a forklift can reach into the base 42 and lift the base 42 without manual handling, which facilitates installation.

[0050] In some embodiments, the base 42 includes a base body 421, a limiting member 422, and a buffer member 423. The transformer 41 is mounted on the base body 421 along a second direction. The buffer member 423 is disposed between the transformer 41 and the base body 421 so that the transformer 41 and the base body 421 elastically abut against each other. The limiting member 422 is disposed on the periphery of the base body 421 to restrict the movement of the base body 421 within the third chamber 113.

[0051] In some embodiments, such as Figure 9 As shown, a buffer 423 is provided between the base body 421 and the transformer 41, so that the transformer 41 and the base body 421 can elastically abut against each other. The transformer 41 will vibrate during operation. The buffer 423 absorbs the vibration energy through deformation, reducing the impact of vibration on the internal solder joints, capacitors and other components of the transformer 41, and improving the stability of the transformer 41. Moreover, as an elastic medium, the buffer 423 can prevent the transformer 41 from directly rigidly contacting the base 42, and prevent local stress concentration caused by impact.

[0052] In some embodiments, the electrical device 40 further includes a fuse 43, which is disposed within the second return air duct 1032, and the fuse 43 and the return air vent 116 are arranged opposite each other in a third direction, such as... Figure 7 As shown, the fuse 43 is located in the second return air channel 1032, which is the fourth chamber 114. The fuse 43 is arranged opposite to the return air inlet 116 along the third direction, so that the gas around the fuse 43 can flow into the temperature control device 30 through the return air inlet 116. The temperature control device 30 can draw in the air around the fuse 43 through the return air inlet 116, so that the air in the second chamber 112 and the third chamber 113 flows into the fourth chamber 114 to regulate the gas temperature around the fuse 43.

[0053] In some embodiments, such as Figure 2 and Figure 5 As shown, assuming a high ambient temperature in summer, the temperature control device 30 delivers cool air into the first chamber 111 through the air inlet 115. At this time, the cool air is within the first air inlet channel 1011, and it contacts the air inlet guide plate 131, adjusting the airflow direction. This allows the cool air to be blown into the second chamber 112 through the first air guide port 133. Here, the cool air is within the second air inlet channel 1012, thus cooling the battery component 44 within the second chamber 112 and preventing heat concentration in the battery component 44 due to high ambient temperature. The cool air then flows along the second direction to the third chamber. Chamber 113, the second chamber 112 and the third chamber 113 form a flow channel 102 to cool the transformer 41. During operation, the temperature of the heat sink of the battery component 44 can reach above 60°C. The surface temperature of the transformer 41 is above 60°C during operation. Therefore, the cooling gradient is utilized to achieve a cooling effect. Moreover, the battery component 44 is more sensitive to temperature. According to Arrhenius law, for every 10°C increase in temperature, the lifespan of the battery component 44 is halved. Therefore, cooling of the battery component 44 is prioritized to extend its lifespan.

[0054] Then, the air flows into the fourth chamber 114 through the second air duct 134. The temperature of the fuse 43 during operation is higher than that of the transformer 41, so the fuse 43 in the fourth chamber 114 is cooled down. At this time, the air is in the first return air channel 1031. After the air enters the fourth chamber 114, the temperature control device 30 draws in the gas in the fourth chamber 114. The gas returns to the interior of the temperature control device 30 through the return air duct 116.
