Description

Technical Field

[0001] This utility model relates to the field of air-cooled energy storage containers, and in particular to an adjustable-depth air duct and energy storage system. Background Technology

[0002] In the design and application of containerized energy storage systems, the thermal management system is a crucial guarantee for energy storage safety. Currently, air cooling and liquid cooling are the two most mainstream and common thermal management methods for containerized energy storage. Among them, the air-cooled thermal management system reduces battery temperature through gas convection, and has advantages such as simple structure, easy maintenance, and low cost. Depending on the different thermal management methods, air-cooled thermal management systems can be further divided into centralized multi-cluster thermal management mode and single-cluster thermal management mode. Centralized multi-cluster thermal management has poor heat dissipation efficiency, heat dissipation speed, and temperature uniformity, while the single-cluster thermal management mode adopts a one-cluster-one-management approach, with each battery cluster rack using a separate air conditioner for thermal management control, effectively solving problems such as slow heat dissipation speed and poor temperature uniformity, thus improving thermal management efficiency.

[0003] During the product manufacturing process, multiple battery clusters are integrated inside the energy storage container. Due to the influence of production processes and manufacturing errors, there are more or less errors in the distance between the battery clusters and the air conditioners. These distance errors cause some problems for the installation of the air ducts. The air ducts and air conditioners are difficult to fit completely, and there are installation gaps of varying sizes between them, causing the air conditioner to leak cold air. This affects the cooling effect of the air conditioner and the temperature control of the battery system. It is necessary to repeatedly adjust the installation of the clusters and air conditioners, and even to re-customize air conditioning ducts of different specifications to reduce the installation gap, reduce cold air leakage, and meet product performance requirements. However, this will seriously affect production efficiency, and the product has poor versatility, increasing production costs.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0048] like Figures 1 to 8As shown in the figure, this application embodiment provides an adjustable-depth air duct 100, including: an air duct body 1, an air guide duct 2, and a movable air duct 3. The air duct body 1 has an air duct cavity for introducing cold air to one side of the air conditioning unit 200. The air guide duct 2 is detachably connected to the air duct body 1, and the air guide duct 2 has an air guide cavity that communicates with the air duct cavity. The movable air duct 3 is movably connected to the air guide duct 2, and the movable air duct 3 communicates with the air guide cavity. The movable air duct 3 can move along the extension direction of the air guide cavity to adjust the overlap length of the air guide duct 2 and the movable air duct 3, that is, to adjust the total length of the air duct so that the total length of the air duct matches the distance between the air conditioner 300 and the air conditioning unit 200.

[0049] The adjustable-depth air duct 100 design of this application solves the problem of the difficulty in achieving a complete fit between the air duct and the air conditioner 300 in a single-cluster thermal management mode, resulting in installation gaps of varying sizes that cause cold air leakage from the air conditioner 300, affecting its cooling effect and battery system temperature control. The air duct of this application has a movable air duct 3, whose total length can be adjusted by sliding along the air guide duct 2. This eliminates the need for multiple adjustments to the installation position of the air conditioner 300 or the battery cluster bracket 200, ensuring a complete fit between the air duct and the air conditioner 300. The air duct of this application is convenient to install and simple to operate, reducing unnecessary secondary processing, shortening labor time, and improving efficiency. Furthermore, the air duct of this application can be used in various air-cooled container air duct structures, demonstrating strong versatility.

[0050] In some possible implementations, the movable air duct 3 is slidably disposed within the air guide cavity, and the movable air duct 3 can slide along the air guide cavity to be partially pushed into or pulled out of the air guide cavity. The outer diameter of the movable air duct 3 is smaller than the inner diameter of the air guide cavity, allowing it to move along the air guide cavity. The outer wall of the movable air duct 3 is in contact with the inner wall of the air guide duct 2 to prevent cold air leakage.

[0051] In some possible implementations, the installation depth adjustable air duct 100 includes a limiting member 4, which can be inserted into the air guide duct 2 and the movable air duct 3 to fix the position of the movable air duct 3, thereby completing the installation of the air duct and preventing the movable air duct 3 from being in a movable state and easily shifting, which could lead to air leakage.

[0052] In some possible implementations, such as Figure 1 and Figure 2 As shown, the air duct 2 has multiple fixing holes 21, and each fixing hole 21 is arranged sequentially at intervals along the sliding direction of the movable air duct 3. The movable air duct 3 is provided with a connecting part, and the limiting member 4 can pass through any of the fixing holes 21 and connect to the connecting part on the movable air duct 3.

[0053] Each fixing hole 21 is arranged at intervals along the sliding direction of the movable air duct 3. After adjusting the position of the movable air duct 3 by sliding the movable air duct 3, the movable air duct 3 can be fixed by using a limiting member 4 that passes through the corresponding fixing hole 21 on the air guide duct 2 and is connected to the inner movable air duct 3 with a connecting part.

[0054] In some possible implementations, adjacent fixing holes 21 are connected and the distance between adjacent fixing holes 21 is small, thereby improving the adjustment accuracy of the movable air duct 3. The movable air duct 3 can be fixed after moving a small distance, which can meet the requirements of fine adjustment of the position of the movable air duct 3.

[0055] In some possible implementations, such as Figure 5 As shown, the connecting part includes a connecting hole 31 disposed on the movable air duct 3 and a nut 32 located on the inner surface of the movable air duct 3. The nut 32 is located on the extension line of the connecting hole 31. The limiting member 4 has a screw, which can pass through the fixing hole 21 and the connecting hole 31 in sequence and be threaded onto the nut 32. The nut 32 can be welded and fixed to the inner wall of the movable air duct 3. The threaded groove of the nut 32 is connected to the connecting hole 31 on the movable air duct 3. The limiting member 4 can be a bolt, the bolt's shank passing through the fixing hole 21 and the connecting hole 31 in sequence and being threaded onto the threaded groove of the nut 32, while the bolt's head is limited to the outer wall of the air duct.

[0056] In some possible implementations, such as Figure 5 and Figure 6 As shown, a sealing strip 5 is provided on the port of the movable air duct 3 extending out of the air guide duct 2. The sealing strip makes sealing contact with the surface of the air conditioner 300, and the port of the movable air duct 3 is connected to the air outlet of the air conditioner 300. The sealing strip can seal the gap between the air conditioner 300 and the movable air duct 3. The sealing strip is located on the outside of the port and the air outlet of the air conditioner 300 to prevent cold air leakage.

[0057] In some possible implementations, such as Figure 6 As shown, the sealing strip 5 includes a connecting strip 51 and a tube 52 connecting the connecting strip 51. The tube 52 is filled with air and has an elastic buffering function. The end of the movable air duct 3 extending out of the air guide duct 2 has a bent edge 33. The connecting strip 51 covers the bent edge 33, and the tube 52 protrudes from the end of the movable air duct 3, allowing for convenient sealing contact with the surface of the air conditioner 300. The cross-section of the connecting strip 51 can be U-shaped to fit and fix it to the bent edge 33 at the end of the movable air duct 3.

[0058] In some possible implementations, such as Figure 4As shown, a reinforcing flange 23 is provided on one end of the air guide duct 2, and a connecting flange 22 is provided on the other end of the air guide duct 2. The connecting flange 22 is fitted and connected to the air duct body 1.

[0059] In this embodiment, a reinforcing flange 23 is provided on the port on the air guide 2 into which the movable air guide 3 is inserted. The reinforcing flange 23 can strengthen the structural strength of the end of the air guide 2, prevent the air guide 2 from deforming, and improve the structural strength of the air guide 2.

[0060] This application embodiment also provides an energy storage system, including: a box (not shown), an air conditioner 300 and the aforementioned adjustable-depth air duct 100. A cluster frame 200 is provided inside the box. The air duct body 1 of the adjustable-depth air duct is connected to the cluster frame 200. The air conditioner 300 is provided in the box. The movable air duct 3 extends to the air outlet of the air conditioner 300.

[0061] The enclosure may include a main enclosure and a door. The main enclosure has a door opening that connects to the internal cavity of the main enclosure. A frame 200 is installed inside the main enclosure. The door is connected to the main enclosure for closing or opening the door opening, and an air conditioner 300 is installed on the door. When the door is closed, the surface of the air conditioner 300 comes into contact with the sealing strip 5 at the end of the movable air duct 3, and the air outlet of the air conditioner 300 connects to the movable air duct 3.

[0062] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model.
