Heat Sink and Air Cooling Support Agras T40 PN 001158 Cooling Station for Smart Batteries

In high-performance unmanned aviation, thermal management is the factor that most impacts fleet availability and operational economy. The T40 Battery Air Cooling Support, Part Number 001158 , is a critical piece of ground support equipment . In intensive agricultural spraying operations, high-voltage LiPo/Li-ion batteries experience a significant temperature increase during rapid in-flight discharge and ultra-fast charging on the ground.

Ignoring proper cooling between flight cycles results in accelerated chemical degradation and the risk of cell swelling. Magallan Aerospace Supply provides this unique system as a strategic solution for operators seeking to maximize return on investment (ROI) by ensuring batteries operate within the ideal temperature zone, dramatically extending their cycle count and maintaining aerospace operational safety.

What it is and how it works.

The PN 001158 support is a positioning and forced cooling station designed specifically for the geometry of the Agras T40 smart batteries. It functions as a forced convection heat exchange interface. The support features optimized air ducts that, when coupled to a ventilation unit, direct a high-pressure airflow through the battery's internal dissipation cavities.

The operating principle is the reduction of thermal latency. When a battery finishes a spraying mission, internal heat is retained in the center of the cells. The cooling support allows this heat to be removed homogeneously, preparing the battery to enter the recharge cycle more quickly, without the charger needing to reduce the amperage for thermal protection.

Operational Applications in Aviation and Drones

Reducing Turnaround Time in the Field

It allows the operator to place the newly removed drone battery directly into the cooling stream, reducing the waiting time required to start charging. This is indispensable for operations that utilize the "Uninterruptible Cycle" concept (3 batteries for 1 drone).

Soil Thermal Management Station

It acts as a safe and ventilated place for the batteries to rest between missions, preventing residual heat from the ground or direct solar radiation from increasing the internal temperature of the pack.

Preventive Maintenance and Storage

Used in maintenance, repair, and overhaul (MRO) workshops to stabilize the temperature of batteries that have undergone deep discharge testing or that need to be safely brought to storage voltage.

Technical and Operational Benefits

• Operational Reliability: Prevents premature drone shutdown due to battery overheating on subsequent flights.
• Asset Preservation: Minimizes internal battery resistance caused by heat, maintaining the original discharge capacity (C-Rate) for longer.
• Charging Optimization: Smart chargers identify cooled batteries and apply the maximum charging curve immediately, saving valuable minutes on each recharge.
• Flight Safety: Batteries operated at controlled temperatures have a lower probability of individual cell failures, ensuring stable power delivery.
• Ergonomics and Organization: Keeps batteries out of direct contact with damp soil or soil contaminated with pesticides, preserving the connection terminals.

Key Technical Differentiators

• Airflow Engineering: Internal design with deflectors that ensure air passes through areas of higher heat concentration, and not just the outer casing.
• High-Strength Thermoplastic Material: Constructed from industrial polymer resistant to impact and corrosive chemicals found in the agricultural environment.
• Precise Compatibility: The PN 001158 was molded for a perfect fit with the T40 battery, preventing vibrations or inefficient airflow through side gaps.
• Portability: Lightweight and compact design, easy to integrate into support vans or remotely operated trailers.

Technical Specifications

Compatibility and Installation Requirements

• Compatible Model: Exclusively for Agras T40 drone batteries.
• System Requirements: Must be connected to a forced air source (centrifugal fan or compatible ground cooling system).
• Installation: Position on a flat, level surface. Ensure that the bottom air intake of the support is not obstructed by vegetation or debris.

Important Technical Guidelines and Considerations

1. Duct Cleaning: Check weekly for any buildup of dust or fertilizer residue inside the duct, as this can reduce airflow efficiency.
2. Monitoring: Although the support helps with heat dissipation, the operator should always consult the telemetry on the radio control to confirm that the battery temperature is below 45°C before starting the flight.
3. Use in Extreme Climates: In regions with intense heat (above 35°C ambient temperature), a cooling support becomes mandatory to prevent immediate battery swelling.
