Due to the integration of the main circuit in centralized BMS, the heating of some electronic components is more serious, and it needs to be cooled, otherwise it will affect the function of BMS and even the safety of the battery pack. For example, the patent with publication number CN220914352U discloses a BMS cooling structure, which includes a bracket, a BMS board and a cooling piece. The BMS board is placed in the bracket. The cooling piece includes a substrate, a cooling fin and a support heat transfer piece. The cooling fin is connected to the upper part of the substrate. The support heat transfer piece is located at the lower part of the substrate and abuts against the heat conduction plate on the BMS board. The support heat transfer piece is used to support the substrate and transfer the heat of the BMS board to the cooling fin on the upper part of the substrate. Under the support of the support heat transfer piece, the cooling fin can avoid various electronic components on the BMS board, so that the cooling area of the cooling fin is not affected by the size of the BMS board. However, the cooling effect of the cooling fin itself is limited. If a stronger cooling structure is needed, more cooling fins are needed.
