A battery cell cooling apparatus is provided to improve durability and assembling property of a battery unit and to reduce the production cost by cooling the respective battery cells of the battery unit evenly. A battery cell cooling apparatus includes: many battery cells(1) formed in a panel shape; a holder(5) having a cylinder-shaped central pipe(3) at the center, and an outer pipe(7) which is concentric with the central pipe to dispose the battery cells between the central pipe and the outer piper, wherein each battery cell is disposed along the circumference of the central pipe at regular intervals and in equal angles; and a cooling passage which comprises many inside air holes(9) formed on the central pipe, and many outside air holes(11) formed on the outer pipe, so that a cooling wind flowing between the center and the outside of the holder can move via the battery cells. |
