HS Marston Extruded Aluminium Heat Sink, Undrilled, 1.8°C/W, 200mm
HS Marston extruded aluminium heat sink for passive cooling. 1.8°C/W thermal resistance, 200mm length, undrilled for custom mounting.
The HS Marston Extruded Aluminium Heat Sink is engineered for effective passive cooling in demanding electronic applications. Designed for natural convection, this extruded aluminium heat sink efficiently dissipates heat from power semiconductor devices and assemblies without the need for forced airflow, making it ideal for systems where silent operation and reliability are paramount.
Featuring a black anodised surface finish, it provides enhanced thermal performance and superior corrosion resistance, ensuring long-term durability even in harsh industrial environments. Its undrilled construction offers significant flexibility, allowing for custom, application-specific mounting to suit a wide range of component layouts and thermal management challenges.
Key Features & Benefits
- Efficient Passive Cooling: With a low thermal resistance of approximately 1.8°C/W, it provides reliable heat dissipation for power-dense electronics.
- Robust Construction: Made from extruded aluminium with a protective black anodised finish for optimal heat transfer and environmental resilience.
- Design Flexibility: The undrilled body allows engineers to drill and tap mounting holes precisely where needed, adapting to unique assembly requirements.
- Compact & Effective: A length of 200mm provides a substantial surface area for cooling while maintaining a manageable footprint for integration into control cabinets and electronic enclosures.
This heat sink is exceptionally well-suited for critical thermal management in sectors such as industrial control equipment, power electronics, HVAC systems, and aerospace and defence applications, where consistent performance and component protection are essential.
