Analysis on Air Flow and Cooling Effect according to Number of Air Guide Fins in Battery module

摘要

This paper applied air guide fin on battery module with air cooling system that is used on electric vehicle and used forced convection in order to study the consequent of air flow and cooling effect. The number of air guide fins was increased from 5 to 120 in order to conduct comparative analysis on the relationship between average temperature and average flow velocity of the entire battery cell according to number of air guide fins. The result analyzed the line of air flow in battery cooling channel, compared average temperature of the entire battery cell by the number of air guide fins, and compared the standard deviation of average temperature of each battery cell by the number of air guide fin. The result of the analysis showed that appropriate number of air guide fin lowers vortex production in cooling channel and that the flow velocity of cooling channel and the average temperature of battery cell are close to having an inverse relationship.
