Patent ID: 7955725

Claim:
A package for sodium-sulfur batteries containing a frame in which a plurality of module batteries stacked with providing a space a between upper surface of one module battery and bottom surface of another module battery are disposed in two rows with providing a space b between one row and another row, where air inlets are provided at the positions of a wall face on the side of the one row and a wall face on the side of the another row which correspond to the lowermost module batteries, air inlet louvers are provided at the respective air inlets, an air outlet is provided at ceiling part between the one row and the another row, an air guiding plate A is provided being inclined obliquely and downwardly toward wall face on the side of the one row between bottom surface of module battery constituting the one row and wall face on the side of the one row for every module battery, except for at least the lowermost module battery, with providing a given interval between upper edge portion of the air guiding plate A and wall face on the side of the one row, and besides an air guiding plate B is provided being inclined obliquely and downwardly toward wall face on the side of the another row between bottom surface of module battery constituting the another row and wall face on the side of the another row for every module battery, except for at least the lowermost module battery, with providing a given interval between upper edge portion of the air guiding plate B and wall face on the side of the another row, and a flow rectifying plate A is provided being inclined obliquely and upwardly toward space b between the one row and the another row from the upper surface of module battery constituting the one row, and a flow rectifying plate B is provided being inclined obliquely and upwardly toward space b between the one row and the another row from the upper surface of module battery constituting the another row, with providing a given interval between the flow rectifying plate A and the flow rectifying plate B.
