ABSTRACT:
A battery box for a plurality of electrochemical cells which are arranged in rows one behind the other, a circulating-flow channel being formed by a spacing of the cells from one another within each row, through which a fluid can flow. The circulating-flow channels are all fluidically connected to an inlet channel which tapers in the flow direction and is arranged in the vicinity of the box bottom, and to an outlet channel which expands in the flow direction and is arranged in the vicinity of the box lid. To secure the individual cells, the side walls are provided, in the vicinity of the box bottom, with step-type ledges on which the cells are arranged in a vertically staggered manner in the vicinity of their bottom side edges. The slope of the ledges corresponds in magnitude and direction to the taper of the inlet channel on the bottom side, and the width of a step of the ledge corresponds to the depth of the housing of a cell, plus the corresponding clearance of the circulating-flow channel.
