PURPOSE: A battery case is provided to ensure a facilitate flux distribution to a battery module by reducing a pressure decrease by using an upper side and a side space between the battery outer case and a cell module as a duct channel without installing a separate inner duct. CONSTITUTION: A battery case comprises: a housing(100); a cooling wind inflow part and an outflow part; a plurality of module installation part(300) arranged to continuously mount battery modules(400); a middle barrier(500) arranged in a module mounting part(330) which is positioned in the middle side of the housing and sealing a gap between the battery module and a housing to enable a cooling wind to pass only a battery module; and front barrier(600) which is arranged on the module mounting par, seals a gap between the battery module and housing, and enables a cooling wind to pass the blowing hole and the battery module by forming air holes(620) to separate from each other. |
