1. A battery pack housing comprising:
an inner space that accommodates a plurality of battery modules each including a cathode tab and an anode tab;
a plurality of protruding portions protruding from the inner space, side walls of each of the plurality of protruding portions extend between and adjacent to at least one cathode tab and at least one anode tab of the plurality of battery modules, or extend between and adjacent to at least one cathode tab and at least one other cathode tab, or extend between and adjacent to at least one anode tab and at least one other anode tab, wherein a length and/or a width of the plurality of protruding portions increases or decreases in a direction in which a cooling fluid flows;
one or more groove portions provided between the battery modules and formed in a direction from a lower surface of the battery pack housing toward the inner space, wherein a length and/or a width of the one or more groove portions increases or decreases in a direction in which a cooling fluid flows;
a fluid inlet provided on one side surface of the battery pack housing; and
a fluid outlet provided on the other side surface thereof, wherein the fluid inlet and the fluid outlet are configured to form the cooling fluid flow perpendicular to the cooling fluid flow in the housing respectively.
