Description

Technical Field

[0001] This utility model belongs to the field of battery box technology, and more specifically, it relates to an integrated liquid-cooled energy storage battery box. Background Technology

[0002] Currently, air cooling is the primary method for heat dissipation of energy storage batteries. However, air cooling suffers from drawbacks such as low efficiency, high system noise, and poor environmental adaptability, which to some extent restricts the widespread application of energy storage systems. In contrast, liquid cooling systems, with their significant advantages such as high heat transfer coefficient, large specific heat capacity, and rapid cooling rate, can more effectively control the temperature rise of energy storage battery packs within a smaller range, thereby extending the cycle life of the battery packs. Therefore, exploring more efficient liquid cooling systems for energy storage has become a hot research topic in the industry.

[0003] Based on the above, the inventors have discovered the following problems: When the battery box and liquid cooling plate are produced, the size of the liquid cooling plate needs to be determined to facilitate subsequent installation. When fixing different models of liquid cooling plates, it is necessary to prepare a variety of battery boxes of different specifications. Therefore, different processing molds are also required. The processing technology of the battery box is costly and is not conducive to reducing the production cost of enterprises.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an integrated liquid-cooled energy storage battery box in order to achieve a more practical value. Utility Model Content

Fixing protrusions are installed on the adjusting plates, and the adjusting plates are connected to both ends of the liquid-cooling plate via the fixing protrusions. The length of the adjusting groove is greater than the diameter of the bolt thread.

[0008] Furthermore, an extension plate is installed at the lower part of the fixed plate, and multiple fixing screws are provided on the extension plate. The extension plate is connected to both ends of the lower surface of the box body through the multiple fixing screws.

[0009] Furthermore, the liquid cooling plate is provided with multiple raised strips, which are evenly arranged.

[0010] Furthermore, the lower surface of the enclosure is equipped with transverse and longitudinal reinforcing strips, which are installed in a cross pattern.

At this time, bolts are used to fix the plate through the adjustment groove and the fixed plate. The connecting plate is fixed by bolts, thereby fixing the adjustment plate. The adjustment plate is fixed to the liquid cooling plate by the fixed protrusion. By setting the elongated adjustment groove, the height of the fixed protrusion can be easily adjusted to achieve the purpose of fixing liquid cooling plates of different thicknesses.
