Rectangular Heat Sink Plate With Aluminum Heat Sink and Vertical Parallel Fin Array

Fin pitch and base plate flatness are verified per your drawing during first article review on every aluminum heat sink. Welltop's Dongguan CNC milling line produces these under ISO 9001 process controls. Both govern thermal contact resistance and fin-to-fin airflow uniformity, and both are logged in the production record before dispatch. The rectangular solid base and vertical parallel fin array are produced from your approved drawing; in-process sampling verifies fin height co-planarity and base surface roughness at each machining stage. Applications span consumer electronics power modules, drone ESC cooling, automotive ECU thermal management, and medical equipment electronics assemblies. Surface finish, anodised for improved emissivity or raw machined,follows your drawing callout. Our Dongguan team quotes from your drawing — include to get started. The facility spans approaching 4,000 m², supporting aerospace, oil & gas, and shipbuilding projects.
