Housing for accommodation of e.g. lithium ion cell, in electrical energy storage of hybrid and electrical motor vehicles, has single side opened closure part attached at closed axial side of middle part with opened side of closure part

摘要

The housing (10) has a middle part (12) comprising an external, single side opened cavity (24) and a central cavity (28), which is concentrically closed by the external cavity, where the central cavity retains a radial fan. An inner wall separates the cavities from each other, where the inner wall and a closed axial side of the external cavity comprise a set of through holes (30, 32). A single side opened closure part (16) is attached at a closed axial side of the middle part with an opened side of the closure part or encloses the middle part.
