[0002] To meet the operational needs of equipment or systems, outdoor air-cooled energy storage cabinets (hereinafter referred to as energy storage cabinets) are commonly used to provide power to photovoltaic power stations, wind farms, and communication base stations. The energy storage cabinet contains multiple rows of battery packs. During operation, the battery packs inside the energy storage cabinet will generate heat. In order to keep the battery packs inside the energy storage cabinet at a suitable temperature during operation, the energy storage cabinet is equipped with an air conditioner to dissipate heat from the inside of the energy storage cabinet and the battery packs.

[0003] Currently, when the air conditioner supplies air to the energy storage cabinet for heat dissipation, the air flows along the air duct set inside the energy storage cabinet and then enters the battery pack to dissipate heat from the battery pack. However, the existing air ducts do not provide uniform airflow, resulting in poor heat dissipation performance of the air-cooled energy storage cabinet.

[0004] Therefore, there is an urgent need to propose a new technical solution to address the above problems. Utility Model Content

[0005] One of the objectives of this utility model is to provide a heat dissipation duct that addresses the shortcomings of existing technologies by adjusting the structure of the duct to ensure uniform airflow and thus improve the overall airflow performance of the heat dissipation duct.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A heat dissipation duct includes an air guide and a connector. The side of the connector is embedded in the side of the air guide. An air inlet is provided on one side of the connector, and an air outlet corresponding to the air inlet is provided on one side of the air guide. An air guide plate is provided on the other side of the connector. The surface of the air guide plate has through holes. A first through hole and a second through hole are provided opposite to each other between the connector and the air guide. The through hole is located between the first through hole and the second through hole.

[0008] Preferably, the side of the connector is provided with an air vent, which is located between the first through hole and the through hole.

[0009] Preferably, a sealing ring is provided at the opening edge of the air inlet.

[0010] Preferably, the height of the end of the air guide gradually decreases along the direction of airflow.

[0011] Preferably, the air guide includes an upper air guide shell and a lower air guide shell, wherein the length of the upper air guide shell is less than the length of the lower air guide shell.

[0012] Preferably, the opening of the air outlet is provided with a plurality of wind deflectors, and the plurality of wind deflectors are arranged sequentially along the length direction of the air guide.

[0013] Preferably, the air guide plate includes a first air guide plate and a second air guide plate, one end of the first air guide plate and one end of the second air guide plate are connected, the through hole passes through the first air guide plate and the second air guide plate, and the other ends of the first air guide plate and the other ends of the second air guide plate are inclined along the airflow direction.

[0014] Preferably, the sides of the connector are provided with a first connector and a second connector.

[0015] The second objective of this utility model is to provide an air-cooled energy storage cabinet, including: the heat dissipation duct as described above, and further including: a cabinet body and a battery pack disposed inside the cabinet body. A cabinet door is hinged to the side of the cabinet body, and an air conditioner is provided on the surface of the cabinet door. The air outlet of the air conditioner is connected to the air inlet of the heat dissipation duct. The surface of the battery pack has several air inlet channels, and the air inlet channels and the air outlet of the heat dissipation duct are correspondingly arranged.

[0016] Preferably, the side of the heat dissipation duct is provided with a first connector and a second connector, and the side of the air conditioner is provided with a third connector, which is connected to the first connector and the second connector respectively.

[0017] The beneficial effects of this utility model are as follows: This utility model includes an air guide and a connector. The air guide is used to guide air conditioning air into the battery pack, thereby achieving heat dissipation for the battery pack. The connector is used to connect with the air outlet of the air conditioner, allowing air conditioning air to flow from the connector into the air guide. The side of the connector is embedded in the side of the air guide, and the connector and the air guide are a sealed connection structure.

[0029] The following is in conjunction with the appendix Figures 1-9 The present invention will be further described in detail with reference to specific embodiments, but this is not intended to limit the present invention.

[0030] Example 1

[0031] A heat dissipation duct includes an air guide 1 and a connector 2. The air guide 1 is used to guide air conditioning air into the battery pack 02, thereby achieving heat dissipation for the battery pack 02. The connector 2 is used to connect to the air outlet duct 041 of the air conditioner 04, allowing air conditioning air to flow from the connector 2 into the air guide 1. The side of the connector 2 is embedded in the side of the air guide 1. The connector 2 and the air guide 1 have a sealed connection structure. One side of the connector 2 is provided with an air inlet 21, through which air conditioning air enters the interior of the connector 2. One side of the air guide 1 is provided with an air outlet 11 corresponding to the air inlet 21, through which air conditioning air flows into the battery pack 02. The other side of the connector 2 is provided with... An air guide plate 3 is provided, with its middle section curving upwards towards the air inlet 21. This guide plate directs the air conditioning air to both ends of the air guide component 1. The surface of the air guide plate 3 has through holes 31. A first through hole 4 and a second through hole 5 are disposed opposite to each other between the connector 2 and the air guide component 1. The through hole 31 is located between the first through hole 4 and the second through hole 5. By providing the through hole 31, the air conditioning air can be blown directly onto the battery pack 02. Together with the first through hole 4 and the second through hole 5, the air conditioning air can be blown directly into the battery pack 02 and flow towards both ends of the air guide component 1 before being blown onto the battery pack 02. This achieves cooling of different locations on the battery pack 02, making the airflow more uniform and improving the cooling effect. By providing the air guide plate 3, air can flow out from the first through hole 4, the second through hole 5, and the through hole 31 respectively, making the airflow in the air duct uniform and improving the airflow effect of the heat dissipation air duct. The side of the connector 2 is provided with a first inclined surface 23 and a second inclined surface 24. By setting the inclined surfaces, airflow can be guided, wind resistance can be reduced, and efficiency can be improved.

[0032] In this embodiment, the side of the connector 2 is provided with an air vent 22, which is located between the first through hole 4 and the through hole 31. Because the air conditioning air will sink, by providing the air vent 22, the air conditioning air blown out of the through hole 31 can be compensated for the air conditioning air lost due to the sinking of the air conditioning air, so that the air conditioning air blown out of the through hole 31 has a cooling effect comparable to that of the air conditioning air blown out of other locations.

[0033] In this embodiment, a sealing ring 211 is provided at the edge of the air inlet 21. By providing the sealing ring 211, the sealing effect of the connection between the connector 2 and the air conditioner 04 can be improved.

[0034] Example 2

[0035] The difference between this embodiment and embodiment 1 is that the height of the end of the air guide 1 gradually decreases along the direction of airflow. The end of the air guide 1 is provided with a slope, which can guide the airflow and reduce wind resistance. The air velocity of the air conditioner will gradually decrease during the flow process. By gradually reducing the height of the end of the air guide 1, the air velocity of the air conditioner can be maintained, so that the air outlet 11 at different positions of the air guide 1 has a similar air outlet effect.

[0036] In this embodiment, the air guide 1 includes an upper air guide shell 12 and a lower air guide shell 13, with the length of the upper air guide shell 12 being shorter than the length of the lower air guide shell 13. Because cold air sinks, the shorter upper and longer lower design helps to even out the airflow velocity between the upper air guide shell 12 and the lower air guide shell 13, resulting in more uniform airflow. The length L1 of the upper air guide shell 12 is 500–600 mm, for example, L1 can be 500 mm, 520 mm, 540 mm, 560 mm, 580 mm, or 600 mm. The length L2 of the lower air guide shell 13 is 700–900 mm, for example, L2 can be 700 mm, 720 mm, 740 mm, 760 mm, 780 mm, 800 mm, 820 mm, 840 mm, 860 mm, 880 mm, or 880 mm. Preferably, L1 is 577 mm and L2 is 797 mm.

[0037] In this embodiment, a plurality of wind deflectors 111 are provided at the opening of the air outlet 11, and the plurality of wind deflectors 111 are arranged sequentially along the length of the air guide 1. By setting the wind deflectors 111, the air conditioning air can be prevented from blowing onto the adjacent air intake channels 021 in the battery pack 02 when the air outlet 11 is venting, so that the air conditioning air blowing onto each air intake channel 021 is similar.

[0038] In this embodiment, the air guide plate 3 includes a first air guide vane 32 and a second air guide vane 33. One end of the first air guide vane 32 and one end of the second air guide vane 33 are connected. A through hole 31 passes through the first air guide vane 32 and the second air guide vane 33. The other ends of the first air guide vane 32 and the second air guide vane 33 are inclined along the direction of airflow. The first air guide vane 32 and the second air guide vane 33 are set as inclined surfaces to guide the airflow and reduce wind resistance. This arrangement makes it easier for the air conditioning air to flow to the upper and lower ends of the air guide plate 3, allowing the air conditioning air to flow out from the air outlets 11 at different positions.

[0039] In this embodiment, the sides of the connector 2 are provided with a first connector 6 and a second connector 7. By providing the first connector 6 and the second connector 7, it is convenient to install the heat dissipation duct on the air outlet duct 041 of the air conditioner 04.

[0040] The other structures in this embodiment are the same as those in Embodiment 1, and will not be described again here.

[0041] Example 3

[0042] A wind-cooled energy storage cabinet includes: a heat dissipation duct as described in Embodiment 1 or Embodiment 2, and further includes: a cabinet body 01 and a battery pack 02 disposed inside the cabinet body 01. A cabinet door 03 is hinged to the side of the cabinet body 01. An air conditioner 04 is disposed on the surface of the cabinet door 03. The air outlet duct 041 of the air conditioner 04 is connected to the air inlet 21 of the heat dissipation duct. The surface of the battery pack 02 has a plurality of air inlet ducts 021, and the air inlet ducts 021 and the air outlets 11 of the heat dissipation duct are correspondingly disposed. A first filter 022 is installed at the opening of the air inlet channel 021 to prevent large impurities from entering the air inlet channel 021. A second filter 043 is installed at the opening of the air outlet channel 041 to prevent large impurities in the air conditioner 04 from being blown into the heat dissipation air duct. An air outlet plate 05 is installed on the side of the cabinet 01. The surface of the air outlet plate 05 has several holes for dissipating the cooled air conditioning air, so that the heat in the battery pack 02 can be carried away by the air conditioning air.

[0043] In this embodiment, a first connector 6 and a second connector 7 are arranged opposite each other on the side of the heat dissipation duct, and a third connector 042 is arranged on the side of the air conditioner 04. The third connector 042 is connected to the first connector 6 and the second connector 7 respectively. This arrangement facilitates fixing the heat dissipation duct to the air conditioner 04, so that the air conditioner air can be stably blown into the heat dissipation duct.

[0044] Obviously, this utility model includes an air guide and a connector. The air guide is used to guide the air conditioning air into the battery pack, thereby achieving heat dissipation for the battery pack. The connector is used to connect with the air outlet duct of the air conditioner, allowing the air conditioning air to flow from the connector into the air guide. The side of the connector is embedded in the side of the air guide, and the connector and the air guide are sealed together. One side of the connector has an air inlet, through which the air conditioning air enters the interior of the connector. One side of the air guide has an air outlet corresponding to the air inlet, through which the air conditioning air flows into the battery pack. The other side of the connector has an air guide. The air guide plate has a central section that curves upwards towards the air inlet, directing airflow towards both ends of the air guide component. The surface of the air guide plate has through holes. A first through hole and a second through hole are positioned opposite each other between the connector and the air guide component. The through hole allows airflow to be directly directed towards the battery pack. Combined with the first and second through holes, this ensures the airflow reaches the battery pack directly and flows towards both ends of the air guide component before reaching the battery pack, thus achieving cooling of different areas of the battery pack. This results in more uniform airflow and improved cooling efficiency. This invention, by using an air guide plate, allows air to flow out from the first through hole, the second through hole, and the through hole, resulting in uniform airflow and improved cooling performance.

[0045] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, the utility model is not limited to the specific embodiments described above, and any obvious improvements, substitutions, or modifications made by those skilled in the art based on the utility model are within the protection scope of the utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on the utility model.
