Vapor Chamber Quick Calculations – Do I Need One?

Vapor Chamber Quick Calculations – Do I Need One?

In this blog, I’d like to take you through the early steps I take when determining if a two-phase device, specifically a vapor chamber, might be needed as part of the thermal solution. I’ll eventually do a complementary piece on heat pipes, but in the interest of...

Thermosyphons for Electronics Cooling

This blog is written to give engineers a basic understanding of an often forgotten, but still relevant two-phase cooling solution – thermosyphons. Recently, I visited the Henry Ford Museum in Michigan. A fabulous place that’s steeped in the kind of history that...

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 pipe design guidance 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 sizes of between...

Understanding 3D Vertical Vapor Chambers

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 for...

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...
