THERM ALLOY High Fin Ratio Heat Sinks for high power applications ADVANCED EXTRUSION TECHNOLOGY OPTIMISED FOR FORCED AIR. Up to 20:1 ratio available, providing a competitive alternative to fabricated fins or bonded solutions. High Fin Ratio Extrusions provide increased efficiency for high power applications under forced convection by creating a greater cooling surface. - anodizing or other surface finishes possible Combined with a fan, High Fin Ratio heat sinks provide significant component cooling benefits over system level fans. They incorporate a dedicated fan with a heat sink base to increase localized airflow while improving thermal efficiency. These active fan heat sinks allow for greater thermal performance than can be achieved with a much bigger size passive solution Why use Aavid High Fin Ratio heat sinks with Aavid fans? - Enhanced performance in less space - Increased life and reliability of critical high power components - System airflow is restricted or not possible - Impingement designs cool adjacent components - Skilled design engineers utilizing latest CFD design software - Suitable for a wide range of applications from drivers to power supplies to industrial equipment - No tooling and stock available for standard profiles <\\7/> AA\/in High Fin Ratio Heat Sinks

High Fin Ratio Heat Sinks^ for high power applications STANDARD PROFILES Thermal performance and pressure drop curves are based on uniform thermal load on the heat sink base, 2 m/s air speed for forced convection, 75 °C temperature sink-to-ambient differential, 150 mm cut length of the heat sink.
