Description

Technical Field

[0001] This utility model relates to the field of air-cooled heat dissipation technology, and further to an air-cooled energy storage duct and a power energy storage device. Background Technology

[0002] Air-cooled energy storage systems are new energy equipment that perform peak shaving, valley filling, frequency regulation, and other functions. Internally, they can be divided into a battery compartment and a power distribution compartment. The battery compartment is a device that stores a large number of energy storage batteries in a container and is equipped with a corresponding air duct design.

[0003] The battery racks of the air-cooled energy storage system are spaced at the bottom of the inner side of the enclosure. Openings are provided at the battery rack spacing at the bottom of the enclosure, and a gap is left between the top of the battery racks and the top of the enclosure. Air ducts are located at the top of the battery racks. One end of the air duct connects to the air conditioning outlet, while the other end forms a closed section. Cool air flows through the entire battery compartment and exchanges heat with the batteries, thus removing the heat generated inside the compartment.

[0004] The entire battery cluster shares a single battery air duct with openings spaced at intervals to allow cool air to flow into the batteries below for heat exchange. However, when the air conditioner blows a strong stream of cold air, the cold air blows directly from the opening at the far end of the air duct to the batteries, resulting in less cold airflow near the batteries and higher battery temperatures. This leads to a large temperature difference between the batteries and also has a certain impact on cycle life.

[0005] For those skilled in the art, how to achieve uniform cooling and heat dissipation at all locations in an air-cooled energy storage system is a technical problem that needs to be solved. Utility Model Content

[0006] The core of this utility model is to provide an air-cooled energy storage duct. By setting several airflow guiding components in the cooling duct, the airflow in the cooling duct is guided to the battery cluster below, which helps to improve the uniformity of cooling airflow. The specific solution is as follows:

[0007] A wind-cooled energy storage duct includes a cooling duct and an airflow guiding component. One end of the cooling duct is connected to a cold source, and a plurality of airflow openings are formed on the bottom surface of the cooling duct. Each airflow opening is provided with a corresponding airflow guiding component, and the free end of the airflow guiding component faces the airflow.

[0008] The airflow guiding component includes a fixed base, a rotating plate, and a hinge. The fixed base is fixed to the bottom surface of the cooling air duct and located at the rear edge of the airflow opening. The rotating plate is rotatably connected to the fixed base via the hinge and can be positioned at a specific angle.

[0009] The rotating plate is used to guide the airflow in the cooling duct to the airflow opening and blow it toward the battery cluster below.

[0010] Optionally, a fan is installed on the cooling duct, the fan being used to guide the airflow of the cooling duct to the battery cluster below;

[0011] A temperature sensor is installed below the fan, and the fan adjusts its operating status according to the temperature sensor's detection value.

[0012] Optionally, the cooling duct includes a vertical section, an inclined section, and a horizontal section in sequence. The vertical section is connected to the cooler to introduce air-cooled airflow. The fan is installed in the inclined section, and the airflow opening is located in the horizontal section.

[0013] Optionally, the horizontal segment is composed of several detachable and spliced ​​segments.

[0014] Optionally, the rotating plate includes a hinge plate and a sliding plate, the hinge plate being mounted on the hinge, and the sliding plate being slidably mounted on the hinge plate.

[0015] Optionally, the edge of the sliding plate is provided with a folded edge, which surrounds the edge of the hinge plate to achieve sliding assembly;

[0016] The sliding plate is provided with a waist hole, and the hinge plate is equipped with a locking bolt, which is used to cooperate with the waist hole to achieve the positioning of the sliding plate.

[0017] Optionally, the airflow guiding component includes a driver for driving the rotating plate to rotate to adjust the angle.

[0018] Optionally, the width of the airflow guiding member does not exceed 1 / 2 of the width of the cooling duct.

[0019] This utility model also provides an electric energy storage device, including the air-cooled energy storage duct described in any of the above claims.

[0020] This utility model provides an air-cooled energy storage duct. One end of the cooling duct is connected to a cold source to introduce cold air. Several airflow openings are formed on the bottom surface of the cooling duct, through which cold air can be introduced downwards. Each airflow opening is provided with an airflow guiding component. The fixing seat of the airflow guiding component is fixed to the bottom surface of the cooling duct and located at the rear edge of the airflow opening. A rotating plate is rotatably connected to the fixing seat through a hinge and can be positioned at a specific angle. The rotating plate intercepts part of the airflow in the cooling duct and guides the intercepted airflow to the corresponding airflow opening, blowing it towards the battery cluster below. Compared with a structure without airflow guidance, this can make the airflow form a more uniform distribution effect, avoiding the airflow from being concentrated and blown towards the rear section of the cooling duct, thereby achieving uniform cooling and heat dissipation at all locations of the energy storage system.

Detailed Implementation

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the following will provide a detailed description of the air-cooled energy storage duct and power energy storage device of this utility model in conjunction with the accompanying drawings and specific embodiments.

[0031] This utility model provides an air-cooled energy storage duct, including a cooling duct 1 and an airflow guiding component 2, etc. This air-cooled energy storage duct is applied to a power energy storage device and can distribute the cooling airflow evenly, avoiding the cooling airflow from concentrating in the rear section of the cooling duct 1.

[0032] One end of cooling duct 1 is connected to a cold source, combined with Figure 1As shown, the left end of the cooling air duct 1 is connected to the cold source, and the cooling airflow flows from left to right. The cold source can be an air conditioner, which delivers cooling airflow to the cooling air duct 1 to provide cooling gas.

[0033] Combination Figure 1 As shown, the battery cluster is supported by a battery rack 41 to hold several battery modules 4. A cooling duct 1 is located above the battery cluster, and several airflow openings 11 are opened on the bottom surface of the cooling duct 1. The airflow openings 11 are distributed at intervals, and the position of the airflow openings 11 is set according to the heat dissipation required by the battery cluster below.

[0034] Each airflow opening 11 is provided with an airflow guiding component 2. The airflow guiding component 2 is located behind the airflow opening 11. Here, "front and back" refers to the direction of airflow inbound, with the airflow inbound direction being "front" and the airflow outbound direction being "back". Figure 1 The left side of the image represents the front, and the right side represents the back.

[0035] The airflow guiding component 2 is connected to the cooling air duct 1 at one end as a hinged end and at the other end as a free end. The free end of the airflow guiding component 2 faces the airflow, that is, the airflow guiding component 2 faces the upper left. The airflow guiding component 2 is used to block the lateral flow of airflow and can guide the airflow to the airflow opening 11 below.

[0036] The airflow guiding component 2 includes a fixed base 21, a rotating plate 22, and a hinge 23. The fixed base 21 is fixed to the bottom surface of the cooling air duct 1 and is located at the rear edge of the airflow opening 11. The rotating plate 22 is rotatably connected to the fixed base 21 through the hinge 23. The hinge 23 is a hinge structure with a certain damping, which can be positioned at a specific angle and can be maintained at a specific angle when there is no other external force.

[0037] Combination Figure 1 As shown, the rotating plate 22 is tilted towards the upper left. The left edge of the rotating plate 22 is a free end, and the right edge is a hinged end. The rotating plate 22 extends into the cooling air duct 1 and has a solid plate surface. The rotating plate 22 is used to guide the airflow in the cooling air duct 1 to the airflow opening 11 and blow it towards the battery cluster below. The airflow in the cooling air duct 1 flows laterally. When the airflow passes through the rotating plate 22, it is blocked. The rotating plate 22 is tilted, which can guide a local airflow inside the cooling air duct 1 to the outside of the cooling air duct 1 and reach the battery cluster below.

[0038] If the cooling duct 1 does not have an airflow guiding component 2, when the airflow passes through the airflow opening 11, only a small amount of airflow will flow out of the airflow opening 11. Due to inertia, the airflow will flow towards the rear of the cooling duct 1, mainly flowing downwards from the rear airflow opening 11. The airflow velocity at the front is faster, resulting in even less airflow flowing out of the front airflow opening 11, leading to poor cooling of the battery modules at the front. This invention addresses this by installing an airflow guiding component 2 on the cooling duct 1. When the airflow passes through the airflow guiding component 2, it can be blocked and guided to the battery cluster below, allowing the battery modules at the front to receive sufficient cooling. This also enables a more uniform airflow distribution, preventing the airflow from concentrating towards the rear of the cooling duct 1, thereby achieving uniform cooling of all parts of the energy storage system.

[0039] Based on the above scheme, combined with Figure 1 As shown, this invention installs a fan 3 on the cooling duct 1. When the fan 3 operates, it generates an active airflow, which is used to actively guide the airflow from the cooling duct 1 to the battery clusters below. A temperature sensor is installed below the fan 3, and the fan 3 adjusts its operating state based on the sensor's readings. The fan 3 is positioned in the forward area of ​​the cooling duct 1, and can actively cool the battery clusters in the forward position through active drive. The fan 3 can actively generate cooling airflow, which can be used to supplement cooling for battery clusters in other areas that are not adequately cooled.

[0040] Combination Figure 1 As shown, the cooling duct 1 sequentially includes a vertical section 101, an inclined section 102, and a horizontal section 103, arranged from front to back. Airflow in the vertical section 101 flows from bottom to top, airflow in the horizontal section 103 flows from left to right, and airflow in the inclined section 102 flows obliquely upwards. Airflow in the vertical section 101 flows into the horizontal section 103 after passing through the inclined section 102. The lower part of the vertical section 101 is connected to the cooler 5 to introduce air-cooled airflow. The fan 3 is installed in the inclined section 102. When the cooling airflow passes through the inclined section 102, it can actively guide the cooling airflow to the battery cluster below. Because the airflow in the inclined section 102 changes from vertical to horizontal, achieving airflow reversal, it is inconvenient to install the airflow guiding component 2 in the inclined section 102, thus enabling active airflow discharge. Airflow openings 11 are provided in the horizontal section 103, guiding the cooling airflow in the horizontal section 103 to the battery cluster below.

[0041] Combination Figure 1 , Figure 2As shown, the horizontal section 103 is composed of several detachable and splicable segments. The vertical section 101, the inclined section 102, and the local horizontal section 103 form a variable pipe structure, while other parts of the horizontal section 103 are formed by splicing several segments. The segments of the horizontal section 103 can be spliced ​​together or fixed together by flange structures. The detachable assembly method facilitates transportation. Furthermore, the splicing structure is versatile; the number of segments can be increased or decreased according to specific application scenarios, thus achieving flexible adaptation.

[0042] Based on any of the above technical solutions and their combinations, this utility model provides a specific structure for an airflow guiding component 2, combined with... Figure 3 , Figure 4 As shown, the rotating plate 22 includes a hinge plate 221 and a sliding plate 222. One end of the hinge plate 221 is mounted on a hinge 23, and the sliding plate 222 is slidably fitted onto the hinge plate 221. There is a partial overlap between the hinge plate 221 and the sliding plate 222. By changing the relative position of the sliding plate 222 and the hinge plate 221, the total area of ​​the rotating plate 22 can be adjusted. The larger the total area of ​​the rotating plate 22, the stronger the obstruction effect on the airflow, and the more airflow can be guided downward to the battery cluster. When the hinge plate 221 and the sliding plate 222 are slidably adjusted to their maximum length, the length of the rotating plate 22 in this invention is less than the length of the airflow opening 11.

[0043] Combination Figure 4 , Figure 5 , Figure 6 As shown, the edge of the sliding plate 222 is provided with a folded edge 223, which is folded 180 degrees relative to the sliding plate 222. The folded edge 223 surrounds the edge of the hinge plate 221 to achieve sliding assembly. The folded edge 223 and the sliding plate 222 are located on the front and back sides of the hinge plate 221, respectively.

[0044] A slotted hole 224 is provided on the sliding plate 222, and a locking bolt 225 is installed on the hinge plate 221. The locking bolt 225 is used to cooperate with the slotted hole 224 to position the sliding plate 222. Figure 4 , Figure 5 As shown, three parallel through holes 224 are provided on the sliding plate 222, and threaded holes are provided on the hinge plate 221, for connection. Figure 5 As shown, a plurality of connecting posts 226 are provided on the hinge plate 221, and each connecting post 226 is provided with a corresponding threaded hole. Figure 5Three connecting posts 226 are provided for each of the waist holes 224, and locking bolts 225 can be screwed onto any one of the connecting posts 226. The locking bolts 225 pass through the waist holes 224 and are threaded into the threaded holes, pressing against the surface of the sliding plate 222 to achieve relative fixation between the hinge plate 221 and the sliding plate 222. When it is necessary to adjust the relative position of the hinge plate 221 and the sliding plate 222, first loosen the locking bolts 225, and then tighten them again after adjustment. When fixing the hinge plate 221 and the sliding plate 222, all three locking bolts 225 can be screwed on simultaneously for a better fixing effect.

[0045] Installing the connecting post 226 on the hinge plate 221 eliminates the need for excessively large openings in the hinge plate 221, thus effectively preventing air leakage. Of course, this invention does not exclude structures with oblong holes in the hinge plate 221; such specific arrangements should be included within the protection scope of this invention.

[0046] The area of ​​each rotating plate 22 in the cooling air duct 1 can be adjusted according to different positions. For example, the rotating plate 22 closer to the front has a larger area.

[0047] Furthermore, the airflow guiding component 2 includes a driver for driving the rotating plate 22 to rotate to adjust the angle. The driver can be a motor, electric cylinder, or pneumatic cylinder. The angle adjustment of the rotating plate 22 is achieved automatically and in real time. The angles of each rotating plate 22 can be the same or different. When the angles are different, the angles between the rotating plate 22 and the airflow opening 11 can be arranged in a larger-than-smaller order, thereby introducing more cooling airflow to the battery module in the closer position and forming more sufficient heat dissipation and cooling in front.

[0048] When the actuator adopts a telescopic structure, such as an electric cylinder or a pneumatic cylinder, one end of the actuator can be hinged to the sliding plate 222. The actuator realizes the angle adjustment of the rotating plate 22 through telescopic movement. While driving the angle adjustment of the rotating plate 22, the actuator can also drive the sliding plate 222 to slide relative to the hinge plate 221, adjust the total area of ​​the rotating plate 22, achieve the linkage adjustment effect of angle adjustment and area adjustment, and realize automatic fine adjustment.

[0049] Specifically, the width of the airflow guiding component 2 does not exceed 1 / 2 of the width of the cooling duct 1, which can avoid excessive obstruction of the airflow in the cooling duct 1.

[0050] This utility model also provides an energy storage device, including the above-mentioned air-cooled energy storage duct, which can achieve the above-mentioned technical effects.

[0051] The airflow guiding component 2 in this utility model not only increases the speed and stability of the airflow, but also adds a hinge 23 to adjust the angle and a retractable rotating plate 22 to facilitate the adjustment of the air inlet and outlet. It can also be adapted to various battery arrangement schemes. When the temperature of a certain battery is high, the corresponding air guide plate can be adjusted, thereby achieving higher energy efficiency, reducing the temperature difference between individual batteries, and thus improving the heat dissipation effect of the battery cluster.

[0052] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
