Abstract
The improvement of heat transfer in water cooling passage of lithium-ion battery is numerically studied by employing trapezoidal vortex generators. Battery Design StudioⓇ software is used for modeling electro-chemical heat generation in the battery. The conjugated heat transfer is analyzed with the commercial package STAR-CCM+ in terms of inlet flow velocities. The result shows that vortex generator enhances the convective heat transfer by developing thermal boundary layers and secondary flows in downstream, which results in reducing the average temperature of the battery by about 1℃. The heat transfer is enhanced for the whole inlet velocity, while the pressure loss sharply increases at more than inlet velocity of 0.1m/s. The optimum inlet velocity is around 0.1m/s for in terms of the heat transfer and pressure loss.
