1. A battery cell retention frame, comprising:
a central cooling plate member having first and second manifold portions and first and second intermediate walls disposed between and coupled to the first and second manifold portions, the central cooling plate member having a length along a longitudinal axis that is larger than a width of the central cooling plate member in a lateral direction perpendicular to the longitudinal axis, the first and second manifold portions extending adjacent to opposite longitudinal side edges of the first and second intermediate walls, the first and second intermediate walls having opposing surfaces spaced from one another and defining an internal cooling channel therebetween;
the first manifold portion having a first longitudinal aperture extending along the longitudinal axis of the central cooling plate member, and an inlet aperture extending through a surface of the first manifold portion and fluidly communicating with the first longitudinal aperture, the first manifold portion having a first flow aperture that extends substantially an entire length of the first manifold portion and is in communication with the first longitudinal aperture of the first manifold portion and with the internal cooling channel;
the second manifold portion having a second longitudinal aperture extending along the longitudinal axis of the central cooling plate member, and an outlet aperture extending through a surface of the second manifold portion and fluidly communicating with the second longitudinal aperture, the second manifold portion having a second flow aperture that extends substantially an entire length of the second manifold portion and is in communication with the second longitudinal aperture of the second manifold portion and with the internal cooling channel;
first and second exterior plates being coupled to the first and second manifold portions, respectively, of the central cooling plate member and extending along the longitudinal axis of the central cooling plate member with the first manifold portion being directly between the first exterior plate and the first and second intermediate walls and the second manifold portion being directly between the second exterior plate and the first and second intermediate walls, the first and second exterior plates being perpendicular to the first and second intermediate walls of the central cooling plate member; the first and second intermediate walls having first and second outer surfaces, respectively, disposed opposite to one another and between the first and second exterior plates; and
first and second thermally conductive layers being disposed on the first and second outer surfaces, respectively;
the first manifold portion being disposed between the first and second intermediate walls and the first exterior plate, and the second manifold portion being disposed between the first and second intermediate walls and the second exterior plate; and
the longitudinal axis of the first manifold portion being parallel to an intersection between the central cooling plate member and the first exterior plate.
