Description

Technical Field

[0001] The utility model relates to the technical field of battery heat dissipation, in particular to a heat dissipation duct for a battery assembly. Background Art

[0002] With the development of new energy equipment such as electric vehicles, logistics robots, and electric boats, the use of lithium batteries is becoming more and more widespread. The cell capacity, output power, and battery load are getting larger and larger, and the number of cells is also increasing. As a result, the heat inside the entire battery module is also getting higher and higher. The performance of the battery module is deeply affected by the temperature. How to control the battery module within a reasonable temperature to achieve the best performance and lifespan puts higher requirements on the design of the heat dissipation of the battery module. The existing common battery module heat dissipation solution is mostly natural heat dissipation. The battery cell group is fixed in the bracket cell slot. After assembly, the battery cell itself can be exposed to the air for natural heat dissipation. Space, after the battery cell group is assembled in the shell, the heat it generates will first be transferred to the air inside the shell, and the shell absorbs the internal heat and then transfers it to the external environment of the shell, so as to achieve the heat dissipation function of the entire battery module; however, when this heat dissipation solution is actually used, due to long-term work, the efficiency of natural heat dissipation will gradually fail to keep up with the heat generation efficiency of the battery module, causing the heat accumulated inside the battery module to become higher and higher, and then the battery module will work in a high temperature environment, which will reduce the service life of the entire battery module and also affect the performance of the single battery cell. Moreover, for battery modules with more battery cells, their performance will be affected more. Utility Model Content

Then, when the exhaust pipe is exhausted, part of the airflow around the mounting plate 1 can directly flow into the heat dissipation groove 3, and the remaining airflow will first flow into the main transverse groove 8 and the secondary transverse groove 6, and then flow through the guide groove 7 and the through groove 5 on one side, so that the mounting plate 1 can be fixed by the mounting groove 2. The airflow around the plate 1 can flow around the battery core group 4, thereby enhancing the heat dissipation effect of the mounting plate 1 on the battery core group 4, thereby ensuring that the battery core group 4 can operate within a suitable temperature and ensure the performance of the battery core group 4. The heat dissipation duct composed of the heat dissipation groove 3, the through groove 5, the guide groove 7, the main transverse groove 8 and the secondary transverse groove 6 allows the airflow to flow around each group of battery core groups 4.

[0019] As a preferred embodiment, the mounting plate 1 has a rectangular structure, and multiple sets of mounting grooves 2 are provided on the upper and lower surfaces of the mounting plate 1 in parallel and at equal intervals, and the axial length of the mounting groove 2 is equal to the width of the mounting plate 1. At the same time, the cross-section formed by the combination of the mounting plate 1 and the mounting groove 2 is a V-shaped structure.

[0020] In this embodiment, if Figure 1 、 Figure 2 and Figure 3 The structural arrangement of the mounting plate 1 and the mounting groove 2 can not only facilitate the mounting plate 1 to fix the battery core group 4 in the mounting groove 2, but also facilitate the splicing of multiple groups of mounting plates 1, thereby ensuring that the mounting plate 1 can fix multiple groups of battery core groups 4.

At the same time, connecting pieces are provided at the positions of the end faces of both ends of the mounting plate 1 relative to the opening of the heat dissipation groove 3, and the connecting pieces have a U-shaped structure.

[0024] In this embodiment, if Figure 1 、 Figure 2 and Figure 4 The opening of the heat dissipation groove 3 allows the external air flow to flow from one end of the mounting plate 1 to the other end, thereby helping to enhance the heat dissipation efficiency of the mounting plate 1. At the same time, the setting of the connecting piece allows the two ends of the mounting plate 1 to be connected to the exhaust pipe or the air injection pipe according to actual needs, so that the air flow around the mounting plate 1 can flow.

[0025] As a preferred embodiment, two groups of support plates 9 are symmetrically connected in the heat dissipation groove 3. Both groups of support plates 9 are long strip structures, and the length of the support plates 9 is less than the length of the heat dissipation groove 3, while the thickness of the support plates 9 is equal to the height of the heat dissipation groove 3. At the same time, the support plates 9 and the adjacent guide grooves 7 are staggered.

[0026] In this embodiment, if Figure 2 、 Figure 3 and Figure 4 The setting of the support plate 9 can not only help enhance the overall structural strength of the mounting plate 1, but also perform corresponding diversion processing on the airflow flowing into the heat dissipation slot 3, so that the airflow can flow evenly in the heat dissipation slot 3, thereby helping enhance the heat dissipation efficiency of the mounting plate 1.

[0027] As a preferred embodiment, multiple groups of through grooves 5 are opened at the top and bottom of the heat dissipation groove 3 in parallel and at equal intervals. The through grooves 5 are rectangular in structure, and the number and position of the through grooves 5 correspond one to one to the installation grooves 2. At the same time, the guide grooves 7 and the through grooves 5 are combined together to form a W-shaped structure.
