Description

Technical Field

[0001] The utility model relates to an air duct structure and an energy storage container, belonging to the technical field of battery pack power supply devices. Background Art

[0002] The energy storage container is a lithium battery structure that integrates multiple battery boxes into a container. It has the advantages of fast on-site deployment and high degree of production standardization. When the battery system is running, the battery cells will generate a lot of heat. In order to effectively dissipate the heat of the battery system, a set of ventilation and heat dissipation ducts needs to be set up inside the container.

[0003] The Chinese utility model patent with the authorization announcement number CN217507467U discloses an energy storage container system air duct structure, including an equal flow air duct, the equal flow air duct includes a top plate and a bottom plate arranged in parallel, the two sides of the top plate and the bottom plate are closed and connected by side plates, and the two ends are closed and connected by end plates, and the top plate and the bottom plate are both isosceles trapezoidal structures, so that the equal flow air duct is wedge-shaped as a whole. A partition is vertically connected between the top plate and the bottom plate, and the partition separates the inner cavity of the equal flow air duct into two air supply channels, and each air supply channel is correspondingly provided with an air inlet, and the air inlet is connected to the air conditioner through an air conditioning connecting pipe. There are multiple air outlets spaced apart along the length direction on the bottom plate. A flow equalizing plate (i.e., guide plate) is provided on both sides of the air outlet in each air supply channel. The guide plates on both sides are symmetrical with respect to the partition and arranged in a V shape to guide the airflow in the air supply channel to the air outlet. The length of the guide plate gradually shortens as the distance from the guide plate to the air inlet increases. There are multiple ventilation holes on the guide plate, and the number of ventilation holes gradually decreases as the distance from each guide plate to the air inlet increases. The guide plate is rotatably connected to the flow equalizing air duct, and an adjustment handle for adjusting the angle of the guide plate is provided outside the flow equalizing air duct.

[0004] In the above patent, the airflow in the two air supply channels needs to flow backward through the ventilation holes on the guide plate, that is, the guide plate has two functions, drainage and flow-through, but these two effects are actually contradictory. In order to obtain a better drainage effect, the entity ratio of the guide plate is required to be high. In order to obtain a better flow-through effect, more ventilation holes are required to be opened on the guide plate, which will affect the entity ratio of the guide plate, and it is difficult to take both into account. In addition, the guide plate and the partition are not in contact, and there is a certain gap between the two. In this way, the airflow guided to the partition by the guide plate can easily escape directly backward through the gap, which will affect the amount of air discharged from the air outlet and affect the heat dissipation effect of the air outlet.

DETAILED DESCRIPTION

[0040] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0041] In view of the technical problems existing in the prior art, the basic technical concept of the utility model is to set the guide plate as a solid plate, and the end of the guide plate is connected to the partition, so that the function of the guide plate is to guide the flow, and it is no longer responsible for the flow, and the airflow will not escape from between the guide plate and the partition, ensuring that the gas guided can be discharged instead of escaping backward. At the same time, the guide plate includes a guide section that gradually approaches the partition from front to back, and there is a gap between the end of the guide section and the corresponding side plate for the airflow to pass from front to back. The gap formed by the guide section of each guide plate and the corresponding side plate gradually decreases from front to back, balancing the uniformity of the front and rear exhaust airflow.

[0042] Embodiment of the energy storage container in the utility model:

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the energy storage container includes a box body 9 and a battery cluster frame 11 arranged in the box body 9, air conditioners 10 are respectively arranged at both ends of the box body 9 in the length direction, the battery cluster frame 11 has a cooling air duct, and an air duct structure 100 is arranged on the box body 9 to connect with the cooling air duct of the battery cluster frame 11. The air duct structure 100 is located on the top of the battery cluster frame 11, and is used to transport the cold air blown out by the air conditioner 10 to the cooling air duct of the battery cluster frame 11, so as to dissipate heat for the battery system.

[0044] like Figure 7 and Figure 8 As shown, the air duct structure 100 includes a top plate 1 and a partition plate 2 connected to the bottom surface of the top plate 1. The partition plate 2 is perpendicular to the top plate 1 and is located in the middle of the top plate 1 in the left-right direction. The left and right sides of the top plate 1 are respectively connected to side plates 3, which are also perpendicular to the top plate 1. Air supply channels are formed between the side plates 3 and the partition plate 2. An air inlet structure is provided at the front end of the air supply channel. The air inlet structure in this embodiment is an air inlet pipe 4 connected to the front end of the air supply channel, combined with Fig. 9 As shown, the air inlet pipe 4 is a prismatic structure, the rear end of the air inlet pipe 4 is connected to the air supply channel, the front end is connected to the air outlet of the air conditioner 10, and the pipe cross-section of the air inlet pipe 4 gradually decreases from front to back.

[0045] like Figure 7 and Figure 8As shown, a rear end plate 5 is connected between the top plate 1 and the rear ends of the left and right side plates 3, and the rear end plate 5 is also perpendicular to the top plate 1. In the present embodiment, the lower side of the entire air duct structure 100 is an open structure, which constitutes an air outlet structure on the lower side of the air duct structure 100, that is, the air duct structure 100 does not include a bottom plate, so as to directly connect with the cooling air duct of the battery cluster rack 11 in the energy storage container 9, so that the cold air entering the air duct structure 100 can directly flow downward into the cooling air duct of the battery cluster rack 11, thereby making the air outlet more convenient and ensuring the heat dissipation effect of the air outlet.

[0046] A plurality of guide plates 6 arranged front and back are connected to the top plate 1 in each air supply channel. The guide plates 6 are also perpendicular to the top plate 1, and are solid plates. At the same time, the ends of the guide plates 6 are connected to the partition 2. The guide plates 6 include a guide section 61 that gradually approaches the partition 2 from front to back. The utility model adopts a solid plate as the guide plate 6, and utilizes its solid plate surface for drainage. During the drainage process, no airflow will pass through the guide plate 6, and no airflow will escape backward from between the guide plate 6 and the partition 2, thereby ensuring the drainage effect.

[0047] like Figure 8 As shown, there is a gap between the end of the guide section 61 and the corresponding side plate 3 for airflow to pass from front to back, ensuring the through-flow function, allowing the airflow to flow backward, so that the two effects of guide and through-flow are achieved through two structures, which is easier to take into account. At the same time, the gap formed by the guide section 61 of each guide plate 6 and the corresponding side plate 3 gradually decreases from front to back, ensuring that the airflow can be more evenly distributed to each guide plate 6 in the process of flowing from front to back, ensuring the uniformity of the front and rear exhaust airflow, and then ensuring the air outlet and heat dissipation effect.

[0048] In this embodiment, the drainage section 61 is a straight plate arranged obliquely, and the drainage plate 6 also includes a vertical section 62 vertically connected to the partition 2, and the vertical section 62 is connected to the drainage section 61, and the two are arranged at an obtuse angle. In addition, the drainage plates 6 on both sides of the partition 2 are arranged symmetrically, and the vertical sections 62 of each drainage plate 6 are equal in length. The length of the drainage section 61 of each drainage plate 6 gradually increases from front to back, thereby ensuring that the interval formed by the drainage section 61 and the corresponding side plate 3 gradually decreases from front to back. The guide sections 61 of each guide plate 6 are arranged in parallel, so that after the cold air enters each air supply channel, it is intercepted by the guide sections 61 of each guide plate 6 in turn during the process of flowing from front to back, and guided to the vertical section 62, and then flows downward to the cooling air duct of the battery cluster rack 11. The front guide plate 6 has a small interception area, but a large air volume in the front, and the rear guide plate 6 has a large interception area, but the air volume decreases toward the back, thereby ensuring the uniformity of the front and rear exhaust airflows, and further ensuring the uniformity of the heat dissipation of the battery system in the battery cluster rack 11.

[0049] like Figure 8As shown, the top plate 1 includes two parts, the front part is rectangular, and the rear part is an isosceles trapezoid, so the side plate 3 is a bent plate with a certain bending angle. Among them, the front part ensures that the cold air entering the air supply channel from the front end can flow smoothly backwards, so that it is intercepted by each drainage section 61 to achieve drainage and outflow; the amount of air entering the rear part is small, and the cross-sectional area of ​​the rear part gradually decreases, so that the air volume converges. At the same time, the rear end of the partition 2 extends to the rear part of the top plate 1 and does not contact the rear end plate 5. The rear end drainage plate is connected to the rear end of the partition 2. The rear side of the partition 2 forms a convergent air duct connected to each air supply channel between the two side plates 3 and the rear end plate 5, thereby increasing the air volume of the rear end of the air duct structure 100 and ensuring the consistency of the front and rear air volumes.

[0050] In addition, a straight rear wind shield 7 is connected to the bottom surface of the top plate 1 in the converging air duct. The rear wind shield 7 is arranged perpendicular to the partition 2 and is also perpendicular to the top plate 1. There is a gap between the rear wind shield 7 and the two side plates 3, and the rear wind shield 7 guides the airflow downward. In addition, two rear wind shields 7 are provided in parallel in front and back, and the lengths of the two rear wind shields 7 are equal, so the gaps to the side plates 3 are not equal, and the gap formed on the front side is larger, so that more airflow can flow to the rear side.

[0051] In addition, each air supply channel is connected to a straight front wind shield 8 on the bottom surface of the top plate 1. The front wind shield 8 is perpendicular to the top plate 1. The front wind shield 8 is located on the front side of the front end guide plate. The end of the front wind shield 8 is vertically connected to the partition 2. The width of the front wind shield 8 in the left and right directions is smaller than the width of the front end guide plate in the left and right directions. The front wind shield 8 can directly guide the airflow to flow downward, and because it is arranged closest to the front and is in the area with the largest air volume, there is no need to set an inclined guide section.

[0052] To sum up, compared with the prior art, the utility model separates the two functions of drainage and flow-through. The drainage plate 6 is a solid plate to facilitate drainage. The drainage section 61 of the drainage plate 6 and the gap formed by the corresponding side plate 3 are responsible for flow-through. The two effects of drainage and flow-through are achieved through two structures, which are easier to take into account. In addition, through a series of factors such as the size of each drainage plate 6, the layout position, the shape design of the top plate 1, the length design of the partition 2, etc., the uniformity of the front and rear exhaust airflow is guaranteed, thereby ensuring the air outlet and heat dissipation effect.

[0053] In other embodiments of the energy storage container: the air duct structure may include a bottom plate, and the lower side is not an open structure. In this case, air outlet holes need to be opened on the bottom plate, and the air outlet holes constitute the air outlet structure. The positions of the air outlet holes correspond to the guide plates and are located in front of the corresponding guide plates. Of course, if the air duct structure also includes a front wind shield and a rear wind shield, it is also necessary to open air outlet holes on the bottom plate in front of the front wind shield and the rear wind shield.

[0054] In other implementations of the energy storage container: the front wind shield may no longer be provided, and after the cold air enters the air supply channel, the first thing it contacts is the front-end guide plate.

[0055] In other embodiments of the energy storage container, the number of the rear wind shield plate may be only one. Of course, in other embodiments, the rear wind shield plate may not be provided, and the entire converging air duct may be a through cavity.

[0056] In other embodiments of the energy storage container: the partition can be directly extended to connect with the rear end plate. In this case, there is no converging air duct structure, and the entire air duct structure is divided into two independent air supply channels by the partition.

[0057] In other embodiments of the energy storage container: the shape of the top plate can be an isosceles trapezoid as a whole, or a rectangle as a whole. In both cases, the side plates are flat plates and do not need to be bent.

[0058] In other embodiments of the energy storage container: the drainage sections of each drainage plate may not be parallel, that is, the angle between the vertical section and the drainage section of each drainage plate is not equal from front to back, but may gradually increase from front to back, or some of the drainage sections may not be parallel and are arranged at a certain angle.

[0059] In other embodiments of the energy storage container: the vertical section lengths of the guide plates may not be equal, but gradually increase from front to back. In this case, the guide section lengths of the guide plates may be equal or unequal.

[0060] In other embodiments of the energy storage container: when the drainage section is a straight plate arranged at an angle, the drainage plate may not include a vertical section, that is, the drainage plate is only composed of the drainage section, and the end of the drainage section is directly connected to the partition; in other embodiments, the drainage section may also be an arc-shaped plate, and the drainage plate may include a vertical section vertically connected to the partition, and the vertical section is connected to the arc-shaped plate. Of course, the vertical section may not be included, and the arc-shaped plate is directly connected to the partition.

[0061] In other embodiments of the energy storage container: the air inlet structure provided at the front end of the air supply channel may also be an air inlet, which is then connected to other pipelines when in use.

[0062] The embodiment of the air duct structure in the present invention is as follows: the specific structure of the air duct structure is the same as the air duct structure in the above energy storage container embodiment, and will not be repeated here.

[0063] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The patent protection scope of the present invention shall be based on the claims. All equivalent structural changes made using the description and drawings of the present invention shall be included in the protection scope of the present invention.
