A first fin is formed on a first inside wall surface to protrude therefrom. The first fin exchanges heat between fluid and the first inside wall surface. A first fluid passage is divided between a first region that is a space where the first fin is arranged, and a second region that is a space where the first fin is not arranged. Fluid flows from the second region into the first region. The first fin includes an inflow port through which fluid flows into the first region, and an outflow port through which fluid flows out of the first region. The first fin is formed to extend from the inflow port to the outflow port. An area of the inflow port is larger than a cross-sectional area of the first fluid passage when viewed in a flow direction of fluid.

An energy storage container and an assembly method thereof are provided. The energy storage container includes a container body, an air duct, and an air guide. The container body is provided with at least one battery rack. The air duct is arranged on a top portion of the battery rack. The air guide communicates with the air duct and the battery rack. The air guide includes a first connecting portion, a flexible air guide portion, and a second connecting portion. The first connecting portion is connected to the air duct, the second connecting portion is connected to the battery rack, and the flexible air guide portion is connected to both the first connecting portion and the second connecting portion.

A battery pack includes cylindrical batteries, a thermal diffusing plate, and a casing. The thermal diffusing plate holds the cylindrical batteries. The casing houses the cylindrical batteries and the thermal diffusing plate. The casing includes a first inner surface, inner surfaces other than the first inner surface, a first outer surface, and outer surfaces other than the first outer surface. The first inner surface is located between the first outer surface and the thermal diffusing plate. The heat transfer coefficient between the first outer surface and an outside air of the casing is lower than the heat transfer coefficient between each of the outer surfaces other than the first outer surface and the outside air of the casing.
