Cross-cut heat sinks are produced through standard extrusion followed by a slotting process that creates rectangular pins. These cross-cuts enhance thermal performance by promoting turbulence, which disrupts the stagnant air boundary layers formed on the extruded fins. The omnidirectional configuration allows air to approach from any direction, ensuring effective cooling even if the airflow is not perfectly straight or parallel.
The S815 Series is manufactured using aluminum alloy 6063-T5, which has good mechanical and thermal characteristics. The fins are optimized for medium- to high-airflow rates (1.0-3.0 m/sec or 200-600 LFM).

Notes: RSA refers to the thermal resistance from the heat sink to ambient air; Thermal resistance data are for reference only.
Please note all thermal resistance data are for reference only. They may vary from application to application. Please contact us if you would like us to perform thermal analysis or determine the actual thermal resistance in your system.
The S815 series is optimized for medium to high airflow rates. For low airflow or natural convection applications, please contact us for a cost-effective custom design.
The S815 series is designed to work with thermal grease and adhesive tapes. We recommend 3M 8810 as the thermal tapes. Please contact us for custom heat sinks using different attachment methods (such as push pins, spring-loaded screws, etc.).
