Description

Technical Field

[0001] This utility model relates to an air-cooled heat dissipation structure for an energy storage cabinet and the energy storage cabinet itself, and is an improvement on the heat dissipation performance of the energy storage cabinet. Background Technology

[0002] With the continuous development of the energy storage field, integrated energy storage cabinets are gradually being used independently in industrial and commercial environments. Traditional energy storage cabinets mainly use liquid cooling systems for temperature control, but the design and maintenance of liquid cooling systems are relatively complex, requiring special piping layouts and daily maintenance. This not only increases the construction cost of the system but also increases the future maintenance burden.

[0003] Currently, the industrial air conditioners for air-cooled distributed energy storage cabinets are mainly placed at the front of the battery clusters. This can easily lead to loud noise at the front of the energy storage cabinet, inconvenience in operation and maintenance, and an unsightly appearance. In addition, the air duct design makes it difficult to ensure that the air volume received by each battery module is uniform, resulting in excessive temperature differences between the battery modules and seriously affecting the cycle life of the cells. Utility Model Content

[0004] The purpose of this invention is to provide an air-cooled heat dissipation structure for an energy storage cabinet and an energy storage cabinet in which the air-cooled components deliver more balanced airflow to each installation chamber, which helps to improve the heat dissipation uniformity of each battery pack, thereby increasing the service life of the battery pack.

[0005] This utility model is achieved through the following technical solution.

[0006] A wind-cooled heat dissipation structure for an energy storage cabinet includes:

[0007] The cabinet has an internal battery compartment with multiple mounting chambers for installing battery packs.

[0008] An air-cooling component is installed inside the cabinet, the air-cooling component having an air outlet for outputting cold air;

[0009] The air duct assembly includes a first air duct for receiving cold air and a plurality of second air ducts connected to the first air duct. The first air duct has a first air outlet that connects to the air outlet, and the second air ducts have a second air outlet for outputting cold air. Each mounting chamber has at least one heat dissipation hole for supplying cold air into the mounting chamber, and each heat dissipation hole in the mounting chamber is connected to one of the second air outlets. The diameter of the second air outlet is proportional to the air path distance to the first air outlet to balance the cold air output of each second air outlet.

[0010] As a further improvement of this utility model, the installation chamber is connected to the internal space of the cabinet, and the air-cooling component has an air inlet that is connected to the internal space of the cabinet and is used to absorb the gas inside the cabinet.

[0011] As a further improvement of this utility model, the air duct assembly is located at the top of the cabinet body and is installed on the top surface of the battery compartment.

[0012] As a further improvement of this utility model, the heat dissipation holes on the mounting chamber are connected to the corresponding second air vents through the air guide channel. There is a gap between the outer wall of the mounting chamber and the side wall of the cabinet. The side wall of the mounting chamber, the side wall of the cabinet, and two air guide plates respectively arranged on both sides of the second air vents enclose and form the air guide channel.

[0013] As a further improvement of this utility model, each of the air guide channels connects to multiple mounting chambers arranged sequentially along the height direction, and the number of heat dissipation holes on the mounting chambers arranged sequentially downward along the height direction gradually increases.

[0014] An energy storage cabinet includes a wind-cooled heat dissipation structure of an energy storage cabinet as described in the above technical solution, wherein a battery pack is installed in each of the mounting chambers, and the heat dissipation holes are arranged facing the battery pack.

[0015] As a further improvement of this utility model, the air-cooling component includes a first air-cooling component and a second air-cooling component, the air outlet is formed on the first air-cooling component, and the second air-cooling component is used to dissipate heat for the first air-cooling component.

[0016] As a further improvement of this utility model, the cabinet is provided with openable and closable cabinet doors corresponding to the first air-cooling component and the second air-cooling component.

[0017] As a further improvement of this utility model, the cabinet door corresponding to the first air-cooling component is provided with an installation notch for accommodating the first air-cooling component.

[0018] As a further improvement of this utility model, the cabinet body is provided with a mounting component for installing the first air-cooling component, the mounting component having a receiving cavity for accommodating the first air-cooling component; the second air-cooling component is disposed below the mounting component, and the two are separated by a baffle.

[0019] The beneficial effects of this utility model are:

[0020] 1. The diameter of the second air duct is proportional to the air path distance to the first air duct. That is, the shorter the air path distance from the second air duct to the first air duct, the smaller the diameter of the second air duct. This automatically compensates for the pressure loss caused by resistance when the cold air is transported in the air duct group 3, making the air volume obtained by the installation chambers connected to different second air ducts more balanced. This helps to improve the heat dissipation uniformity of each battery pack, thereby improving the service life of the battery pack.

[0021] 2. The air-cooled component has an air inlet that connects to the internal space of the cabinet and is used to absorb the gas inside the cabinet. By using the air inlet to absorb the gas inside the cabinet, the hotter gas is prevented from remaining in the cabinet for a long time, which further improves the heat dissipation efficiency of the battery pack.

[0030] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0031] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the construction shown in the accompanying drawings. The terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively. These are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0032] Example 1:

[0033] A wind-cooled heat dissipation structure for an energy storage box, referring to Figures 1-7 The system includes a cabinet 1, a cooling assembly 2 housed inside the cabinet 1, and a connecting duct assembly 3. The cabinet 1 contains a battery compartment 4 with multiple mounting chambers 41 for installing battery packs. The cooling assembly 2 has an air outlet 21 for outputting cool air. The duct assembly 3 delivers the cool air output from the cooling assembly 2 to the mounting chambers 41 of the battery compartment 4 to dissipate heat from the battery packs. Specifically, the duct assembly 3 includes a first duct 31 for receiving cool air and multiple second ducts 32 connected to the first duct 31. The second air duct 32 connects to the first air duct 31. The first air duct 31 has a first air duct 311 that connects to the air outlet 21. The second air duct 32 has a second air duct 321 for outputting cold air. Each mounting chamber 41 has a heat dissipation hole 42 on its side wall for supplying cold air into the mounting chamber 41. The heat dissipation hole 42 is connected to one of the second air ducts 321. The diameter of the second air duct 321 is proportional to the air path distance to the first air duct 311 to balance the cold air output of each second air duct 321.

[0034] Typically, because the air path distance between each second air vent 321 and the first air vent 311 is different—that is, the cold air entering the air duct assembly 3 from the first air vent 311 encounters different flow resistances during its delivery to each second air vent 321—specifically, the longer the air path distance, the greater the pressure loss during delivery, resulting in a smaller air volume delivered to the second air vent 321. Therefore, to ensure a relatively balanced air volume for each mounting chamber 41, the diameter of the second air vent 321 is set to be proportional to its air path distance to the first air vent 311. That is, the shorter the air path distance from the second air vent 321 to the first air vent 311, the smaller the diameter of the second air vent 321. This automatically compensates for the pressure loss caused by resistance during the delivery of cold air in the air duct assembly 3, resulting in a more balanced air volume at the heat dissipation holes 42 on the mounting chambers 41 connecting different second air vents 321. This improves the heat dissipation uniformity of each battery pack and extends the battery pack's lifespan.

[0035] In this embodiment, the mounting chamber 41 is connected to the internal space of the cabinet 1. Openings are provided on both sides of the mounting chamber 41. The air-cooling component 2 has an air inlet (not shown in the figure) that is connected to the internal space of the cabinet 1 and is used to absorb the gas inside the cabinet 1. The air inlet is located below the air outlet 21. By using the air inlet to absorb the gas inside the cabinet 1, the gas circulation in the cabinet 1 is accelerated, and the hotter gas is prevented from remaining in the cabinet 1 for a long time, which further improves the heat dissipation efficiency of the battery pack.

[0036] Meanwhile, in order to improve the utilization rate of the internal space of the cabinet 1 and simplify its internal structure, the air duct assembly 3 is set at the top of the cabinet 1 and above the battery compartment 4. It is detachably connected to the battery compartment through the bracket 33. The heat dissipation hole 42 is connected to the corresponding second air vent 321 through the air duct 34. The air duct 34 is formed on both sides of the battery compartment 4. Specifically, there is a gap between the outer wall of the mounting chamber 41 and the side wall of the cabinet 1. Thus, the side wall of the mounting chamber 41, the side wall of the cabinet 1, and the two air guide plates 5 respectively set on both sides of the second air vent 321 enclose the air duct 34. Furthermore, the two sides of the air guide plate 5 are sealed to the side wall of the mounting chamber 41 and the side wall of the cabinet 1 respectively to prevent cold air leakage.

[0037] In addition, each air duct 34 connects to multiple mounting chambers 41 arranged sequentially along the height direction. Each mounting chamber 41 has the same number of heat dissipation holes. Furthermore, the diameter of the heat dissipation holes 42 on the mounting chambers 41 arranged sequentially downwards along the height direction gradually increases. The change in the diameter of the heat dissipation holes 42 can automatically compensate for the pressure loss when the cold air flows in the air duct 34, making the air volume obtained by different mounting chambers 41 connected to the same second air vent 321 more balanced, and further improving the heat dissipation uniformity of each battery pack.

[0038] Example 2:

[0039] An energy storage cabinet includes the air-cooled heat dissipation structure of the energy storage cabinet in Embodiment 1, and a battery pack is installed in each installation chamber. In order to improve the heat dissipation effect of the battery pack, each heat dissipation hole 42 is arranged facing the battery pack, so that the cold air output from the heat dissipation hole 42 can directly blow onto the surface of the battery pack, thereby improving the heat dissipation effect of the battery pack.

[0040] In this embodiment, the air-cooling component 2 is located on the rear side of the cabinet 1. The air-cooling component 2 includes a first air-cooling component 23 and a second air-cooling component 24. The air outlet 21 and the air inlet are both formed on the first air-cooling component 23. The second air-cooling component 24 is used to dissipate heat from the first air-cooling component 23 to ensure the continuous operation of the first air-cooling component 23.

[0041] Furthermore, to facilitate maintenance of the air-cooled component 2, it is located on one side inside the cabinet 1. The cabinet 1 has operable doors 11 corresponding to both the first and second air-cooled components 2 and 24. These doors 11 are designed to open and close relative to the cabinet 1 and are equipped with handles for easy opening and closing. Simultaneously, to facilitate control of the first air-cooled component 23, it features an operation panel. A mounting notch 111 is provided on the cabinet door 11 corresponding to the position of the first air-cooled component 23, allowing operators to control the first air-cooled component 23 without opening the cabinet door 11. This enables simple and quick operation.

[0042] It should be noted that the air-cooled component 2 in this embodiment is set as an air conditioner, specifically a vertical air conditioner, which includes an outdoor unit and an indoor unit. The first air-cooled component 23 is the indoor unit, and the second air-cooled component 24 is the outdoor unit. Both are installed inside the cabinet 1. The air inlet and air outlet 21 are formed on the side of the first air-cooled component 23 near the battery compartment 4. The air outlet 21 is located above the air inlet, and the outdoor unit is located below the indoor unit. The cabinet door 11 corresponding to the indoor unit is provided with a group of ventilation holes to facilitate the removal of heat from the cabinet 1 when the outdoor unit is working.

[0043] In this embodiment, the cabinet 1 is provided with a mounting component 6 for installing the first air-cooling component 23. The mounting component 6 has a receiving cavity for accommodating the first air-cooling component 23. The second air-cooling component 24 is disposed below the mounting component 6, and the two are separated by a baffle. Specifically, the mounting component 6 is a mounting frame, which is assembled from multiple mounting plates.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent substitutions for some of the technical features.
