Air-cooled battery compartment air duct

The invention provides an air-cooled battery compartment air duct, which comprises a main air duct and a hollow assembly, and the hollow assembly has an irregular shape; the branch air duct comprises a hollow cuboid; and the branch air duct is connected with the main air duct through the main and branch joints. According to the embodiment of the invention, the main air duct and the branch air ducts with unequal sections are utilized, so that static pressure is kept balanced in the main air duct and the branch air ducts in the transmission process of air in the air-cooled battery cabin air duct, the air quantity uniformity between battery columns and battery modules is improved, the battery temperature difference is reduced, and the battery consistency is improved. 本申请提出一种风冷电池舱风道，包括主风道，包括中空组合体，所述中空组合体具有不规则形状；支风道，包括中空长方体；以及主支接头，所述支风道通过所述主支接头与所述主风道连接。根据本申请的实施例，利用不等截面的主风道和支风道，使空气在风冷电池舱风道的传输过程中，静压在主风道和支风道内均保持均衡，从而提升了电池列间和电池模组之间风量均匀性，减小了电池温差，改善了电池一致性。
