Why Air Duct Design Matters in Air-Cooled Energy Storage Systems 

In the world of battery energy storage systems (ESS), thermal management plays a vital role in performance, safety, and system lifespan. Among various thermal strategies, air duct design in air-cooled ESS is a cost-effective and proven approach. At Dagong ESS, we’ve optimized this design to bring superior stability, easy maintenance, and long-term value to clients worldwide.

What Is Air Duct Design in ESS?

Air duct design refers to how airflow is organized inside an energy storage cabinet to control the temperature of lithium iron phosphate (LFP) battery modules. In an air-cooled system, the design ensures steady airflow across batteries, avoiding overheating and energy loss.

Key Types of Airflow Structures

Dagong ESS offers flexible air duct configurations tailored to different project needs:

• Front-to-Rear Airflow: Ideal for sequential cooling in narrow, modular ESS cabinets.

• Vertical or Side Airflow: Used in space-restricted environments, enabling balanced cooling across tall or wide cabinets.

Each layout is engineered to fit specific installation sites—whether it’s indoor, outdoor, rooftop, or a factory environment.

Choosing the Right Duct Design: What to Consider

• Climate of Installation Site: High-temperature areas may need enhanced airflow or stronger fans

• System Size and Density: The more compact the battery arrangement, the more critical the duct precision

• Service & Maintenance Needs: Consider ease of access and filter cleaning frequency

• Application Type: Microgrids, EV charging stations, or C&I usage may each benefit from different airflow strategies

At Dagong ESS, we offer free airflow simulations for your project to ensure ideal design before final delivery.

Longevity & Reliability

With smart airflow engineering and quality LFP batteries, Dagong’s air-cooled ESS systems can operate reliably for:

• 10 to 15 years

• Up to 6000 battery cycles

• Minimal thermal stress degradation

Simple maintenance such as filter replacement and airflow checks helps extend system life and maintain safety.
