Frame for secondary battery and battery module comprising same

Abstract

Disclosed are a frame for a secondary battery capable of improving cooling efficiency of a secondary battery by stably securing a flow path around a cooling plate, and a battery module and a battery pack comprising a frame for a secondary battery. The frame for a secondary battery, according to the present invention, comprises: an upper cooling plate and a lower cooling plate which are formed into plate shapes and are arranged opposite and apart from each other at a specific distance; a main frame comprising four sides which surround the outer periphery of the upper cooling plate and the lower cooling plate, and configured so as to receive the outer periphery portion of a pouch-type secondary battery and so that two or more frames can be stacked; and a support member provided between the upper cooling plate and the lower cooling plate for supporting the two cooling plates.

Description

technical field [0001] This application claims the benefit of Korean Patent Application No. 10-2013-0131169 filed on October 31, 2013 with the Korean Intellectual Property Office and Korean Patent Application No. 10-2014-0148143 filed on October 29, 2014, which The disclosure is hereby incorporated by reference in its entirety. [0002] The present disclosure relates to a battery, and more particularly, to a frame for a secondary battery, which is used when manufacturing a battery module including a plurality of secondary batteries, and a battery module including the same. Background technique [0003] Currently, commercially available secondary batteries include nickel-cadmium, nickel-hydrogen, nickel-zinc, and lithium secondary batteries. Among them, lithium secondary batteries have attracted a lot of attention because compared with nickel-based secondary batteries, lithium secondary batteries have a small memory effect which is extremely small to allow unconstrained char...

Problems solved by technology

[0012] Such deformation of the cooling plate may compress or block the channels, thereby disturbing the flow of outside air through the channels and thereby reducing the efficiency of cooling the secondary battery by the cooling plate

Although some configurations such as forming ribs (beads) on the cooling plate in order to prevent such deformation have been proposed, because such ribs themselves may also be deformed, they still cannot stably ensure the channels.
