After being diverted by the diverter plate 24, it is blown onto the battery module 6 from the ventilation slot 9 on the right side. The flowing air takes away the heat emitted by the battery module 6 and is blown out from the ventilation slot 9 on the left side, and finally discharged to the outside from the heat dissipation slot 11 on the left side, so as to achieve a continuous cooling effect;
