The gas delivery device can be, for example, a fan, but not limited thereto), and then each of the plurality of air guides respectively guides the heat dissipation gas to its corresponding gas Circulation Department. For example, the heat dissipation gas can be guided into the gas circulation part 1110 by the guide part 1120 , the heat dissipation gas can be guided into the gas circulation part 1130 by the guide part 1140 , and the heat dissipation gas can be guided into the gas circulation part 1150 by the guide part 1160 .

The thickness of the wall portion 1108 gradually increases from the intake end 1107 to the end 1109 , so that the inner channel width 1106 of the intake portion 110 gradually decreases from the intake end 1107 to the end 1109 . In this way, the flow velocity of the gas in the intake portion 1100 can be gradually increased from the intake end 1107 to the end 1109 (through the increase in the flow velocity at the end, the defect of decreasing the flow rate at the end can be compensated for), so as to prevent the intake portion 1100 from approaching the end The gas flow rate at 1109 is too low, and it can be avoided that the gas flow rate in the gas flow part 1190 disposed at the end 1109 is too low. In a specific embodiment, the wall thickness of the wall portion 1108 does not need to gradually increase from the intake end 1107 to the end 1109 , but only needs to set the inner channel width 1106 of the intake portion 110 to be from the intake end 1107 to the end 1109 It is sufficient to decrease gradually, which can also achieve the effect of preventing the gas flow rate in the intake portion 1100 near the end 1109 from being too low, and preventing the gas flow rate in the gas flow portion 1190 disposed at the end 1109 from being too low.

The disposition direction of the air guide portion 1120 and the air guide portion 1125 may be opposite, the disposition direction of the air guide portion 1140 and the air guide portion 1145 may be opposite, and the disposition direction of the air guide portion 1160 and the air guide portion 1165 may be opposite.

Please also refer to the second picture A and the second picture B. The second diagram A illustrates a partial schematic diagram of a specific embodiment of the novel battery box system, and the second B diagram also illustrates a partial schematic diagram of a specific embodiment of the novel battery box system. In the embodiment shown in the second A and the second B, the gas flow portion 2110 has a fin portion 2112, and the fin portion 2112 may include one or more fins (eg, fins 2112A, 2112B, 2112C, etc.). The fin portion 2112 is extended on the gas flow portion 2110 , and the fin portion 2112 contacts the corresponding battery portion 2200 . In this way, the fins 2112 of the gas circulation portion 2110 can increase the contact area between the gas circulation portion 2110 and the heat dissipation gas, thereby improving the heat dissipation effect on the battery portion 2200 .

Preferably, the heat dissipation gas only contacts the gas circulation part 2110 (especially the fin part 2112 of the gas circulation part 2110 ), but does not directly contact the battery part 2200 . In this way, the battery part 2200 can achieve a dustproof effect. Preferably, the inner channel of the gas circulation portion 2110 extends in a circulation direction 940, the fin portion 2112 extends in the gas circulation portion 2110 in the fin extension direction 930, and the fin extension direction of the fin portion 2112 is parallel. in the flow direction of the gas flow part 2110 . It should be understood that the arrangement of the fin portion 2112 can make the fin portion 2112 have a flow guiding function, which can help guide the heat dissipation gas to circulate in the gas circulation portion 2110 .
