Abstract
In the present disclosure, disclosed are a frame for secondary batteries, which prevents gas from flowing into a cooling channel or a duct connected to it, when such gas is generated from secondary batteries; and a battery module comprising the same. A frame for secondary batteries according to the present disclosure comprises: an upper cooling plate which is plate-shaped and made of thermally conductive material; a lower cooling plate which is plate-shaped and made of thermally conductive material and is placed spaced apart from the upper cooling plate by a predetermined distance to face the upper cooling plate so that a channel is formed in a space between the upper cooling plate and the lower cooling plate; and a main frame which comprises four unit frames with both ends being connected to each other, encompasses the outer peripheral portions of the upper cooling plate and the lower cooling plate, allows an outer peripheral portion of a pouch-type secondary battery to be mounted thereon, comprises openings formed in the side surfaces of two of the unit frames for the channel to be opened, and has uneven parts, corresponding to each other, respectively formed on upper and lower p…
