Product details
Optimized for automotive electronics, the 127783 by Wakefield-Vette sets new standards in Thermal - Heat Sinks reliability. This AEC-Q200 qualified thermal solution addresses unique challenges in electric vehicle power systems, combining robust construction with exceptional thermal performance.The Top Mount Skived design provides precise flatness ( 0.05mm/m ) required for automotive power modules. The manufacturing process eliminates internal stresses that could lead to micro-cracking in vibration environments.The Bolt On system meets automotive vibration requirements (ISO 16750-3) while allowing for serviceability. The titanium hardware resists galvanic corrosion in wet environments.Square Pin Fins configuration delivers {Thermal Resistance @ Forced Air Flow} in turbulent underhood airflow. The staggered pin arrangement reduces boundary layer thickness by 18% compared to linear fins.The 36.000" (914.40mm) dimension accommodates standard automotive ECU footprints. Crash simulations confirm the design withstands 50g impacts without compromising thermal contact.With 4.000" (101.60mm) coverage, the solution cools multiple power devices simultaneously. The copper-tungsten base plate prevents thermal runaway in parallel configurations.Optimized 1.250" (31.75mm) ensures compatibility with confined spaces in electric vehicle battery management systems. The design prevents fin resonance at common engine vibration frequencies.The 0.58°C/W specification enables fail-operational performance during cooling system faults. The design maintains critical components below 150 C in zero-airflow conditions for 30 minutes.High-conductivity Copper ( 390 W/m K) with nickel-plated finish resists automotive fluids. The material selection meets GMW3097 chemical resistance requirements.
