Accordingly, the cool air volume led out through the second air outlet 24 is more uniform, so that the temperature difference of the system is smaller. The air cooling system 30 may also include an air outlet, which is divided into two paths by a dividing pipeline, and the two paths are respectively led into the air inlet 16 of the first dividing portion 34 and the air inlet 16 of the second dividing portion 36.
The interior of the first flow splitting section 34 and the interior of the second flow splitting section 36 are separated by a second partition 38, and the second partition 38 may be located on the central axis L of the flow guiding section 14.
In certain embodiments, the second duct 22 includes a first sub-duct 40 and a second sub-duct 44 spaced from the first sub-duct 40.

In this way, the heat generating element 92 near the air inlet 16 is enabled to rapidly dissipate heat.
Specifically, the first sub-air outlet 46 is closest to the air inlet 16, and accordingly, the heat generating element 92 corresponding to the first sub-air outlet 46 is also close to the air return inlet of the air cooling system 30, and the temperature at the air return inlet is higher, which affects the working temperature of the heat generating element 92. The first sub-air outlet 46 is located at the outlets of the first sub-air duct 40 and the second sub-air duct 44, so that part of cold air blown out by the first sub-air duct 40 and the second sub-air duct 44 can be blown out from the first sub-air outlet 46 at the same time, the cold air quantity is large, and further the heating element 92 close to the air inlet 16 can quickly dissipate heat, so that the working temperature of the heating element 92 is guaranteed not to be too high, and the temperature difference of the system is reduced.
Referring to fig. 2 and 5, a third partition 50 is disposed in the split portion 12, and the first sub-duct 40 and the second sub-duct 44 are partitioned by the third partition 50. In the embodiment shown in fig. 2, the first partition plate 32 and the third partition plate 50 are disposed in each of the first and second flow dividing portions 34 and 36, and the first partition plate 32 and the third partition plate 50 divide the interior of the first flow dividing portion 34 into the first air duct 20, the first sub air duct 40 and the second sub air duct 44, and divide the air inlet 16 of the first flow dividing portion 34 into the first air inlet 52, the second air inlet 54 and the third air inlet 56.
The first and third partitions 32 and 50 divide the second split part 36 into the first and second air ducts 20, 40 and 44, and divide the air inlet 16 of the second split part 36 into the fourth, fifth and sixth air inlets 58, 60 and 62. The first, second, third, fourth, fifth and sixth air inlets 52, 54, 56, 58, 60, 62 may also be separated by an air inlet ratio.
In some embodiments, the plurality of second air outlets 24 further includes a third sub-air outlet 64, the third sub-air outlet 64 is furthest from the air inlet 16, and a side of the third sub-air outlet 64 away from the air inlet 16 is flush with an inner sidewall of the air guiding portion 14. In this way, the use of the first baffle 28 may be reduced.
Specifically, the side of the third sub-air outlet 64 far from the air inlet 16 is flush with the inner side wall of the air guiding portion 14, so that the inner side wall of the air guiding portion 14 can serve as an air guiding plate at the third sub-air outlet 64, the air guiding plate at the third sub-air outlet 64 is saved, the cost is reduced, and the structure is simplified.
In the illustrated embodiment, the side of the third sub-air outlet 64 remote from the air inlet 16 is flush with the inner side wall of the right plate of the deflector 14.

Referring to fig. 1 and 8, a plurality of second guide plates 72 are further disposed in the guide portion 14, each second guide plate 72 is disposed on a side of a corresponding third air outlet 70 away from the air inlet 16, and the plurality of second guide plates 72 gradually increase in the airflow flowing direction.
In this way, cold air can be blown out from the middle of the guide part 14, so that the area between the heating elements 92 can be radiated, and the temperature difference of the system is reduced.
Specifically, in one embodiment, the energy storage device 200 may include a plurality of heat generating elements 92, the plurality of heat generating elements 92 may be arranged in two rows of heat generating elements 92, the first air outlet 66 may correspond to one row of heat generating elements 92, and the second air outlet 68 may correspond to the other row of heat generating elements 92, with a space between the two rows of heat generating elements 92. The heat generated during the operation of the heat generating elements 92 is accumulated in the area between the two rows of heat generating elements 92, and if no cold air is directly introduced into the area, the heat dissipation speed of the area is slower, so that the temperature difference of the system cannot be smaller.
By arranging the plurality of third air outlets 70 between the two rows of air outlets, the region between the two rows of heating elements 92 can be directly cooled by the cold air blown out from the third air outlets 70, so that the heat dissipation speed of the region is improved, and the temperature difference of the system is smaller.
In the direction of airflow, the second deflectors 72 gradually increase, so that the cold air in the third air duct 26 corresponding to the third air outlet 70 can be divided into cold air with different height layers by the second deflectors 72 gradually increasing, and the cold air is guided into the above-mentioned areas at different positions, thereby realizing that different positions of the area have a certain proportion of cold air for heat dissipation, reducing the temperature difference of the energy storage device 200, reducing the temperature difference of the system, and controlling the temperature difference of the system to be smaller. The provision of a plurality of third air outlets 70 also ensures the structural strength of the flow guiding portion 14. The solid arrows in fig. 8 indicate the direction of airflow.
In some embodiments, the second air outlet 24 and the third air outlet 70 are both elongated, and the length direction of the second air outlet 24 is perpendicular to the length direction of the third air outlet 70.
In this way, the air outlet of the second air outlet 24 and the third air outlet 70 can be more consistent with the configuration of the heating element 92.
Specifically, in the embodiment shown in fig. 2, the length direction of the second air outlet 24 is along the front-rear direction, and the length direction of the third air outlet 70 is along the left-right direction. In the same row of heat generating elements 92, a plurality of heat generating elements 92 are generally arranged in the left-right direction, and different rows of heat generating elements 92 are arranged in the front-rear direction, and a region formed between two adjacent rows of heat generating elements 92 is a long and narrow region extending in the left-right direction.
The first and second air outlets 66 and 68 correspond to two rows of heat generating elements 92, respectively, and the second air outlet 24 of each air outlet may correspond to a middle region of one heat generating element 92 of each row of heat generating elements 92, or a region between two heat generating elements 92.

Thus, the area between the two rows of heating elements 92 corresponding to the fifth air outlet 76 can dissipate heat rapidly.
Specifically, the fourth air outlet 74 and the third air outlet 70 closest to the air inlet 16 together form a fifth air outlet 76, so that the air outlet area of the fifth air outlet 76 is larger, and the air outlet of the cold air is more. Since the area between the two adjacent rows of heating elements 92 corresponding to the third air outlet 70 closest to the air inlet 16 is close to the air return opening of the air cooling system 30, the temperature at the air return opening is relatively high, which affects the heat dissipation speed of the area between the two adjacent rows of heating elements 92. The fifth air outlet 76 has more cold air output, which is beneficial to improving the heat dissipation speed of the area and making the temperature difference of the system smaller.

Because the guide piece 80 is connected with the bottom wall of the third air duct 26 through the connecting piece 78, after the cold air is turned by the guide piece 80, the cold air is not directly blown out from the second air outlet 24, but the turned cold air is rectified through the connecting piece 78, and finally, the direction of the cold air blown out from the second air outlet 24 is more concentrated.
