Further, the number of the second openings 330 is equal to the number of the battery racks 400 and corresponds one-to-one, so that after the cooled air is released from the second openings 330 , the battery racks 400 corresponding to the second openings 330 are in contact with the battery racks 400 corresponding to the second openings 330 , so that the heat Exchange is sufficient.

5 , in some embodiments, the cross-sectional area of one end of the first channel 320 facing the air guide port 350 is larger than the cross-sectional area of the other end, for example, the cross-sectional area of the first channel 320 (the cross-section here refers to a plane perpendicular to the airflow direction) The surface area of intercepting the surface formed by the first channel) gradually decreases from one end toward the air guide 350 to the other end. In some embodiments, the first channel 320 is provided with a first area 321 and a second area 322 along the flow direction of the airflow, and the cross-sectional area of the first area 321 is larger than that of the second area 322 , increasing the flow rate from the first area 321 The air pressure in the second area 322 enables the gas entering the second area 322 to be discharged smoothly, ensuring that the flow rate of the outgoing airflow from each of the second openings 330 is sufficient.
