In this embodiment, the front-rear direction is perpendicular to the left-right direction, and both the left-right direction and the front-rear direction are perpendicular to the up-down direction.

The width of the first ventilation gap 8 may be 1.5mm to 3mm (e.g., 2mm, 2.5mm, 2.7 mm).

In this embodiment, the air duct support 4 may be designed separately to design the inner tuyere 420 according to different split requirements. For example, under the working condition that the temperature of the battery cell far away from the induced draft fan (i.e. at the rear) is higher, the upper and lower heights of the internal air port 420 can be gradually increased from front to rear, or the front section is an opening with a fixed height but the width of the rear end is increased, which is not shown in the figure, so that the air volume of the area where the battery cell is located at the rear is larger than that at the front, and the uniformity and the temperature uniformity are improved; the battery cells are close to the induced draft fan but far away from the air supply port of the system, at the moment, the temperatures of the battery cells close to the induced draft fan and the battery cells far away from the induced draft fan in the energy storage module are high, so that the upper and lower heights of the middle part of the internal air port 420 are kept unchanged, the upper and lower heights of the front part of the internal air port 420 are gradually increased from back to front, the upper and lower heights of the rear part of the internal air port 420 are gradually increased from front to back, as shown in fig. 7 and 10 to 12, the air volume of the area where the battery cells are located relatively far ahead and relatively far behind is relatively large compared with the middle part, and the uniformity and the temperature uniformity are improved; the remaining examples of operating conditions are not listed here.

In addition, based on the design of the structures of the air duct support 4, the first ventilation gap 8 and the like, the second air inlets 9 can also form a uniform distribution form, which is also beneficial to avoiding the problems that wind resistance is increased and the air inlet direction of the battery frame is difficult to match due to different air inlet designs.
