Description

[0002] Thermal management of mobile energy storage cabinets has always been a key focus for energy storage products. The temperature rise of the battery cells and the temperature difference between the cells are key factors affecting the lifespan of the cells, and air cooling is one of the commonly used thermal management methods for energy storage cabinets.

[0003] However, in existing technologies, energy storage cabinets are directly equipped with air conditioners, and the heat dissipation of the energy storage cabinet is directly handled through the air outlets and exhaust vents of the air conditioner. However, the air outlets and exhaust vents only provide airflow to a certain area inside the energy storage cabinet and cannot effectively cover the entire internal area of ​​the energy storage cabinet. For example, the area far from the air outlet cools down slowly, while the area near the air outlet cools down quickly. This makes it easy for large temperature differences to occur inside the energy storage cabinet, making it impossible to finely control the overall temperature inside the energy storage cabinet, which in turn affects the lifespan of the energy storage battery.

[0033] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0034] In the description of this utility model, the use of "first" and "second" is for the purpose of distinguishing technical features only and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of the indicated technical features. It should be understood that such data can be interchanged where appropriate so that the embodiments of the utility model described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0035] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0036] In existing technologies, energy storage cabinets are directly equipped with air conditioners, and the heat dissipation of the energy storage cabinet is directly handled by the air outlets and exhaust vents of the air conditioners. However, the air outlets and exhaust vents only provide airflow to a certain area inside the energy storage cabinet and cannot effectively cover the entire internal area of ​​the energy storage cabinet. For example, the area far from the air outlet cools down slowly, while the area near the air outlet cools down quickly. This makes it easy for large temperature differences to occur inside the energy storage cabinet, making it impossible to finely control the overall temperature inside the energy storage cabinet, which in turn affects the lifespan of the energy storage battery.

[0037] Based on this, this utility model embodiment provides an air duct structure and an air-cooled energy storage cabinet. The air duct structure includes an air duct plate with multiple ventilation openings and multiple baffles. The ventilation openings are arranged vertically, and each baffle is located on the front of the air duct plate, partially obscuring each ventilation opening. Each baffle has multiple slots on both sides, which are used to fix the baffle to the front of the air duct plate by engaging with screws. This air duct design with multiple ventilation openings increases the conveying area of ​​the air duct structure. Simultaneously, the baffles can be vertically adjusted based on the multiple slots, allowing for precise control of the airflow volume and meeting the requirements for large-area and precise airflow control. On the other hand, the air-cooled energy storage cabinet has a cabinet body and a rear door. The cabinet body contains multiple battery boxes, which are arranged vertically. The rear door is located at the back of the cabinet body and houses a cooling unit. The inner side of the rear door has cold air outlets and the aforementioned air duct structure. The cold air outlets are connected to the cooling unit, and the back of the air duct structure is connected to the cold air outlets. Each vent of the air duct structure is connected to the interior of the cabinet body, and the position of each vent corresponds to the position of each battery box. The air duct structure is used to deliver cold air to each battery box. Through the air duct design with multiple vents and adjustable baffles, the amount of cold air delivered to multiple areas inside the air-cooled energy storage cabinet is more uniform, improving the precision of temperature control inside the air-cooled energy storage cabinet, reducing the temperature difference between different areas inside the air-cooled energy storage cabinet, and further improving the service life of the energy storage batteries.

[0038] Therefore, the embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0039] Reference Figure 1 , Figure 2 and Figure 3 As shown, Figure 1This is an overall structural diagram of the air duct structure provided in some embodiments of this utility model. Figure 2 This is an enlarged view of the wind deflector provided in some embodiments of this utility model. Figure 3 This is a partial exploded view of the air duct structure provided in some embodiments of the present utility model. The air duct structure 100 is provided with an air duct plate 110, which is provided with multiple ventilation openings 111 and multiple baffles 112. The ventilation openings 111 are arranged vertically between each other, and the baffles 112 are all located on the front of the air duct plate 110. Each baffle 112 partially covers each ventilation opening 111. Thus, based on the air duct design with multiple ventilation openings 111, the conveying area of ​​the air duct structure is increased.

[0040] Among them, from Figure 2 It is known that multiple slots 113 are provided on both sides of the wind deflector 112. The slots 113 are used to fix the wind deflector 112 to the front of the air duct plate 110 by engaging with screws. The wind deflector can be vertically adjusted based on the multiple slots, thereby finely adjusting the airflow delivery volume and meeting the needs of large-area and fine airflow delivery control.

[0041] Furthermore, from Figure 3 It is known that the air duct structure 100 also includes a heat insulation structure 120, which is embedded in the back of the air duct plate 110. The shape of the heat insulation structure 120 corresponds to the shape of the air duct plate 110, thereby ensuring that the internal temperature of the air duct structure 100 is not disturbed by the outside world and improving the heat insulation performance of the air duct structure 100.

[0042] Furthermore, the air duct structure 100 also includes a plurality of fixing seats 130, which are located on both sides of the air duct plate 110 and are arranged vertically between each other. The fixing seats 130 are used as fixing components for the air duct structure and external components.

[0043] Secondly, referring to Figure 4 , Figure 5 and Figure 6 As shown, Figure 4 This is a back structure diagram of the air-cooled energy storage cabinet provided in some embodiments of this utility model. Figure 5 This is an exploded view of the rear cabinet door provided in some embodiments of this utility model. Figure 6This is a front structural diagram of an air-cooled energy storage cabinet provided in some embodiments of this utility model. The air-cooled energy storage cabinet 200 includes: a cabinet body 210, on which multiple battery boxes 211 are provided, arranged vertically between each battery box 211; a rear door 220, located at the back of the cabinet body 210, with a cooling device inside the rear door 220, a cold air outlet 221 on the inner side of the rear door 220, and an air duct structure 100 as described above. The cold air outlet 221 is connected to the cooling device, and the back of the air duct structure 100 is connected to the cold air outlet 221. The ventilation openings 111 of the air duct structure 100 are all connected to the interior of the cabinet 210. The position of each ventilation opening 111 corresponds to the position of each battery box 211. The air duct structure 100 is used to deliver cold air to each battery box 211. Through the air duct structure 100, the amount of cold air delivered to multiple areas inside the air-cooled energy storage cabinet 200 is more uniform, which improves the precision of temperature control inside the air-cooled energy storage cabinet 100, reduces the temperature difference between different areas inside the air-cooled energy storage cabinet 100, and further improves the service life of the energy storage battery.

[0044] Furthermore, an exhaust vent 222 is provided on the inner side of the rear cabinet door 220. The exhaust vent 222 is located above the air duct structure 100 and is used to connect the interior of the cabinet 210 with the outside.

[0045] Furthermore, the exhaust vent 222 is equipped with a first fan. The exhaust surface of the first fan faces the outside of the cabinet 210, and the suction surface of the first fan faces the inside of the cabinet 210. The first fan is used to exhaust the heat flow inside the cabinet 210 to the outside, thereby quickly exhausting the heat flow inside the cabinet 210 to the outside.

[0046] Furthermore, the exhaust vent 222 has a mesh structure or a honeycomb structure.

[0047] Furthermore, the cabinet 210 is also equipped with a return air duct structure 212, which is located at the top of the cabinet 210. One end of the return air duct structure 212 is connected to the exhaust port 222, and the other end of the return air duct structure 212 is connected to the interior of the cabinet 210. The return air duct structure 212 is used to return the heat flow inside the cabinet 210.

[0048] Furthermore, a second fan is also provided inside the battery box 211. The exhaust surface of the second fan faces the front of the cabinet 210, and the suction surface of the second fan faces the back of the cabinet 210. The second fan is used to exhaust the heat flow inside the battery box 211 to the internal space of the cabinet 200.

[0049] It should be noted that, referring to Figure 7 As shown, Figure 7This is an airflow diagram of the air-cooled energy storage cabinet provided in some embodiments of this utility model. The airflow of the air-cooled energy storage cabinet is as follows: the cold air from the refrigeration device is output to the air duct structure 100 through the cold air outlet 221. Then, the cold air is output to each battery box 211 through multiple ventilation holes 111 in the air duct structure 100. Then, the second fan in each battery box 211 exhausts the heat flow in the battery box 211 to the overall internal space of the cabinet 210. Since the gas density of the heat flow is low, it will move upward. The return air duct structure 212 located at the top of the cabinet 210 will receive this heat flow and guide it to the exhaust port 222. The exhaust port 222 will exhaust it to the outside through the first fan, thereby completing the temperature regulation operation of the air-cooled energy storage cabinet.

[0050] Furthermore, the air duct structure 100 is fixed to the rear cabinet door 220 by means of screws and fixing base 130 engaging with each other, thereby firmly fixing the air duct structure 100 to the inner side of the rear cabinet door 220.

[0051] It should be understood that in this utility model, "at least one (item)" refers to one or more, and "more than one" refers to two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, "A and / or B" can represent three cases: only A exists, only B exists, and both A and B exist simultaneously, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one (item) of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one (item) of a, b, or c can represent: a, b, c, "a and b", "a and c", "b and c", or "a and b and c", where a, b, and c can be single or multiple.

[0052] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
