Battery module cooling structure

Abstract

A battery module cooling structure includes a plurality of battery modules, a plurality of cooling blocks arranged adjacent to the battery modules to cool the battery modules, and a cooling passage which passes through the cooling blocks adjacent to each other and in which cooling water flows. Each of the cooling blocks includes an upper panel that closes an upper portion of the cooling block and forms an upper body, a lower panel that is spaced apart from the upper panel and closes a lower portion of the cooling block, and a side wall that extends along a periphery of the lower panel and has an end fixed to the upper panel.

What is claimed is: 
     
         1 . A battery module cooling structure comprising:
 a plurality of battery modules;   a plurality of cooling blocks that are arranged adjacent to the battery modules and configured to cool the battery modules;   a cooling passage which passes through the cooling blocks adjacent to each other and in which cooling water flows;   a frame that surrounds peripheries of the plurality of battery modules; and   a partition member disposed between the plurality of battery modules to form a boundary between the plurality of battery modules.   
     
     
         2 . The battery module cooling structure of  claim 1 , wherein a gap maintaining part, which allows the battery modules and the cooling blocks to be spaced apart from each other, extends from an inner surface of the frame. 
     
     
         3 . The battery module cooling structure of  claim 1 , wherein each of the cooling blocks is coupled to a lower portion of the partition member.
