SECONDARY BATTERY MODULE HAVING CONDUIT FOR COOLING

摘要

PURPOSE: A secondary battery module is provided to effectively discharge the heat generated in all unit cells included in the secondary battery module due to wide contact area between the unit cell and a heat transfer medium. CONSTITUTION: A secondary battery includes: plural flow channels for cooling(12) which allow a heat transfer medium to flow and is arranged in parallel; a plurality of unit cells arranged between the flow channels for cooling; a supply flow channel supplying the heat transfer medium to the flow channels for cooling; a discharge flow channel discharging the heat transfer medium from the flow channels for cooling; and a spacer(17) which arranged inside the flow channels for cooling and maintains the interval of the flow channels.
