Why Die-Cast Zinc Heat Sinks?

Posted by Adam in Manufacturing MethodsQ&A
Die-cast zinc heat sinks are often ignored because their thermal conductivity is lower than aluminum alloys used in extrusion and Read More

How to Optimize Round Pin Heat Sinks?

Posted by Adam in Q&A
Nusselt number correlations and entropy minimization had been used to optimize heat sinks. The empirical method described in the next Read More

How Orientation Affects Heat Sink Performance?

Posted by Adam in Q&A
The orientation of pin fin heat sink has been found to exert only a minor influence on the heat transfer. Read More

Why Elliptical Pin Heat Sinks?

Elliptical pin heat sinks perform like cross cut (rectangular pin) heat sinks. They both provide very low thermal resistance when Read More

How to Choose Push Pins?

Posted by Adam in Attachment MethodsQ&A
Nylon push pins are the most cost effective push pins, but their glass-transition temperatures (Tg) are lower than 50°C and Read More

Six Steps to Design Your Own Heat Sink
