6 FAQs about [Direct cooling vs liquid cooling of battery pack]
What is the difference between air cooling and direct liquid cooling?
The temperature distribution of direct liquid cooling is similar to air cooling, but it has a larger temperature effect on the battery. So the temperature gradient is larger than the air cooling in this case. The temperature difference of the jacket cooling is largest when the average temperature at the end of the discharge is controlled to 8 °C.
Can different pipe designs improve liquid cooling in lithium-ion battery packs?
In the paper “Optimization of liquid cooling and heat dissipation system of lithium-ion battery packs of automobile” authored by Huanwei Xu, it is demonstrated that different pipe designs can improve the effectiveness of liquid cooling in battery packs.
