TEMPERATURE CORRECTION CONSIDERATIONS Since natural convection heat sink efficiency degrades with decreasing sink-to-ambient temperature differential, correction factor must applied published data application requires sink-to-ambient temperature rise less than 75°C.The corrected thermal resistance obtained multiplying published °C/W/3" data appropriate factor from following table: Temperature Rise (Tsa) Correction Factor 75°C 1.000 70°C 1.017 60°C 1.057 50°C 1.106 40°C 1.170 30°C 1.257 extrusion profile natural convection, thermal resistance (°C/W) more than higher 30°C than 75°C. LENGTH CORRECTION CONSIDERATIONS published extrusion data shows natural convection performance three inch section with centrally located point source heat load. Because heat load assumed point rather than uniformly distributed, thermal resistance does change linearly with length. (The ends very long extrusion would cooler than center therefore transfer heat surrounding little, any.) therefore necessary apply correction factor published data extrusion lengths shorter longer than three inches.The corrected thermal resistance different lengths extrusion obtained multiplying published °C/W/3" data appropriate factor from following table: (see next page)

This table also used determine appropriate length preferred extrusion required obtain desired thermal resistance. Merely divide desired thermal resistance published thermal resistance three inch section obtain correction factor. EXAMPLE: Extrusion 62465 thermal resistance °C/W/3 inch. five inch piece will have thermal resistance 6.24°C/W, using appropriate length correction factor 0.78 [i.e. 8.0°C/W 0.78 6.24°C/W]. Since thermal resistance 6.24°C/W temperature rise 75°C, resistance heat sink temperature rise 50°C will increased temperature correction factor 1.106.There-fore natural convection thermal resistance 6.90°C/W [6.24°C/W 1.106 6.90°C/W].

EXAMPLE: output volume given CFM.The output area inches inches ft2. find velocity: velocity 0.25 Velocity LFM, which 80%, derates LFM. EXAMPLE Aavid part number 579802 (see page used dissipate watts power natural convection. Because dealing with natural convection, refer part graph. Knowing that watts dissipated, follow grid line curve find that watts there temperature rise 75°C.To thermal resistance, divide temperature rise power dissipated, which yields 25°C/W. EXAMPLE same application which blows over sink velocity LFM. addition means that dealing with forced convection therefore refer part graph. Knowing flow, thermal resistance taken from graph.This resistance 8.75°C/W then multiplied power dissipated, watts.This yields temperature rise 26.25°C. difference between natural convection cooling forced cooling feet/minute seen comparing thermal resistance heat sink these environments, 25°C/W 8.75°C/W respectively. DESIGN ASSISTANCE Aavid Thermal Technologies assist design heat sinks both forced natural convection applications. Aavid's technical staff help selection existing "near" optimum extrusion from over 3,000 shapes that have been previously designed tooled Aavid Thermal Technologies design extrusion which best meets requirements application. thermal application needing extruded heat sink should thermally defined explicitly possible before extrusion selected designed.
