Black Dual-Side Auxiliary Heat Sink Fin Inverter-Specific Heat Sink – The "Thermal Barrier Guardian" for IGBT Modules

Daily Functions

• Effectively dissipates heat from IGBT modules to prevent excessive junction temperatures and minimize power loss.

• Assists in cooling capacitor banks and drive circuits to maintain stable electrical parameters for the inverter system.

• Ensures the continuous and reliable operation of small industrial inverter power supplies by managing heat dissipation for core components.

Application Scenarios

• Photovoltaic Energy Field: Used in residential distributed photovoltaic inverters and micro photovoltaic energy storage systems.

• Vehicle-Mounted Power Field: Ideal for new energy vehicle DC-DC inverter modules and inverter power supplies in RVs/trucks.

• Industrial Power Field: Suited for small high-frequency welding inverters and portable emergency inverter power supplies.

• Consumer Electronics Field: Provides efficient heat dissipation for high-power outdoor power supply inverters and household energy storage inverters.

Processing Technology

• Custom Profile Extrusion: Tailored extrusion molds are used to create the 6063 aluminum alloy profile, precisely matching the inverter component layout. This process produces the integrated structure of top fins and side auxiliary teeth in one step, ensuring an optimal heat dissipation area and easy installation compatibility, making it the ideal Aluminum Radiator for high-performance applications.

• T6 Heat Treatment: Solution treatment followed by artificial aging enhances the aluminum alloy’s thermal conductivity and mechanical strength, improving the heat sink’s resistance to thermal deformation and vibration.

• CNC Precision Machining: High-precision CNC machining ensures flatness tolerance within ±0.03mm for IGBT mounting surfaces and component positioning grooves, providing seamless fit and stability for the modules.

• Black Anodization: The black anodizing process creates an 8-12μm thick oxide film, improving the heat sink’s corrosion resistance (tested for ≥1200 hours in salt spray) and enhancing its thermal radiation efficiency, making it suitable for outdoor and vehicle-mounted applications.
