Which inlet flow area affects the heat dissipation of a battery?

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.

What factors influence the heat dissipation effect of a battery?

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.

What are the factors affecting the thermal performance of a battery?

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).

How does the size of the inlet flow area affect heat dissipation?

The size of the inlet flow area (L_inlet) increases in proportion to the radius of the cylindrical battery (r_batt = 0.009 m), to study its effect on the heat dissipation of the battery.

How do flow batteries work?

Flow batteries may vary inside their own technology community but usually they work in ambient temperature ranges. Normally the big volume of electrolyte keeps the system very stable and is unaffected by ambient temperature changes of daily rhythms. Day and night changes compensate often without having stronger influences.

Why is air used for cooling of battery modules arranged in series?

When air is used for cooling of battery modules arranged in series, the middle and rear portion of batteries are at high temperature to the low heat capacity of air. The temperature of the battery pack near the outlet is very high and the temperature distribution is highly non-uniform.
