Design Considerations When Using Heat Pipes (Pt. 2)

Now that we’ve determined which heat pipes can effectively carry the required heat load (Pt 1), we need to ensure we select and size the heat exchanger to dissipate the heat into the surrounding air -based on available air flow. As mentioned in the prior post, this...

Design Considerations When Using Heat Pipes (Pt. 1)

This blog post offers some intermediate level heat sink design guidance when using heat pipes for the most prevalent types of electronics applications: mobile to embedded computing and server type applications with power ranging from 15-150 watts using processor die...

Understanding 3D Vertical Vapor Chambers

Until the mid-2000’s heat pipes were really the only option when designing a high heat-flux heat sink whose condenser was oriented vertically above a horizontal heat source. That’s because they’re easily bent post-production into a variety of shapes including “L” or...

Heat Pipe Reliability – What You Know is Wrong!

Heat Pipe Reliability – What You Know is Wrong!

Last week I gave an IMAPS presentation on heat pipe reliability with Ross Wilcoxon from Rockwell Collins. Thought I'd give you the highlights in graphical form along with some comments. Product reliability is determined by understanding the reliability metrics...

Dust Bunnies are Choking Heat Sinks to Death

My current notebook is about 18 months old and had been running slower and slower for a few months. It was also noticeably hotter causing the fan to run almost continuously. I knew it was that time. About every year and a half I have to take apart my PC to clean out...

Guidelines for Circular Heat Pipe Thermal Testing

For today's blog I'd like to present some work several of my colleagues and I have been working on for submittal to the fall session of the JEDEC Committee: Guidelines for Heat Pipe Thermal Test Set for Testing of Circular Heat Pipes. As we're always open to comments...

Thermal Test Chips – A Quick Explanation

To meet aggressive product time-to-market goals, electrical and mechanical engineers need to work concurrently to envision, model and validate an enormous array of interdependent system requirements. While there’s no doubt that robust thermal modeling of both the...
