For battery thermal management techniques, air cooling and liquid cooling , are widely adopted. However, as batteries develop towards high energy density and high discharge rate, a new thermal management technique needs to be developed to meet its heat dissipation requirements.
Aiming at the heat dissipation requirements of future high-power batteries, in this paper, immersion flow boiling is used for battery thermal management, and its heat transfer characteristics are investigated by both experiments and numerical simulations.
The thermal performance of the battery was simulated and analyzed from two aspects: heat generation (discharge rate, electrode thickness, and continuous charge–discharge cycle) and heat dissipation (ambient temperature, air-cooled heat dissipation conditions, and heat dissipation position).
The area from the inlet to the battery contact is called the inlet flow area, and the size of the inlet flow area will also affect the heat dissipation of the battery. According to the research results of the previous subsection, the inlet airflow velocity condition with the best relative heat dissipation effect is 1 m/s.
The fixed position of the battery and different airflow fields will also influence the heat dissipation effect of the battery. The influence of this factor on the heat dissipation of the battery is studied from four different airflow fields: radial X, axial Z, axial −Z, and axial–radial coupling.
Besides, flow velocity will completely change the heat transfer and flow mechanism of immersion flow boiling. The optimum flow regime can both exchange heat by liquid–vapor phase change and replenish the vaporized working medium by convection, achieving the lower temperature rise and better temperature uniformity in battery.
Boosting flow rate of the electrolyte also increases the heat dissipation capacity. To achieve the highest efficiency of the battery, the optimal flow rate is proposed. ... In …
