Parameters
What is air cooling?
The basic principle of air cooling technology is to take away the heat generated by battery cells through flowing air, thus keeping the battery temperature within a reasonable range. As a heat transfer medium, air can achieve heat exchange through natural convection or forced convection.
Natural convection:Natural convection refers to the phenomenon in which air flows by itself due to the difference in air density caused by temperature differences.In some cases, natural convection can be used to achieve simple thermal management, but this is usually not sufficient to meet high-intensity or high-density energy storage requirements.
Forced convection:Forced convection is to accelerate air flow through fans or other mechanical devices, thereby improving heat exchange efficiency.In container energy storage systems, forced convection is usually used to achieve effective thermal management.
