Silver Aluminum Fin-Type Radiator for Inverters

Daily Functions

• Reliable cooling for home solar inverters
  Helps remove heat from power conversion modules, preventing temperature-related efficiency drops and unexpected shutdowns. This ensures smooth and consistent grid-connection for residential photovoltaic systems.

• Stable performance for industrial-grade inverters
  Supports high-load and continuous-operation conditions—such as motor drives and heavy power conversion—by maintaining a balanced internal temperature. This reduces thermal stress on key components and contributes to longer equipment life with fewer maintenance requirements.

Application Scenarios

• Photovoltaic Inverters
  Ideal for both residential PV inverters and large-scale solar power stations. It dissipates heat from IGBT modules and high-frequency transformers, helping maintain high conversion efficiency and safeguarding grid-connection stability.

• Industrial Variable Frequency Drives (VFDs)
  Used in motor control systems where precise speed and torque are required. When running high-power motors, this radiator keeps the inverter’s power modules cool, improving control accuracy and system reliability.

• Energy Storage Inverters
  Suitable for bidirectional energy storage inverters handling charging and discharging cycles. Effective cooling ensures consistent performance, better energy conversion efficiency, and improved overall system safety.

Processing Technology

• Extrusion Forming
  High-purity aluminum billets are extruded into profiles with uniform, parallel fins—building the core structure required for high-efficiency heat dissipation.

• Precision Cutting
  Each extruded profile is cut accurately to match the installation size of different inverter models, ensuring seamless integration.

• CNC Drilling
  Screw holes on the mounting surface are machined using CNC equipment to ensure reliable assembly, tight module contact, and long-term structural stability.

• Surface Treatment
  Finished with a combination of silver anodizing and natural oxidation. This not only enhances corrosion resistance but also improves the radiator’s thermal conduction efficiency.

• Quality Inspection
  Fin spacing, hole accuracy, and overall dimensions are thoroughly inspected using 3D coordinate measuring systems to ensure consistent precision for every batch.
