  • 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 article is not intended to provide detailed training/equations […]

  • 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 sizes of between 10x10mm to 30x30mm.  I’m using these constraints because throughout the article I’ll […]

  • 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 “U” configurations. Despite the advantages of vapor chambers, better spreading and less thermal resistance, these […]

  • Should I Use Heat Pipes or Vapor Chambers to Cool My Electronics Application

    I’m often asked which two-phase cooling technology, heat pipes or vapor chambers, is best suited for a particular electronics application. While there are some good rules of thumb the answer isn’t always simple. Nonetheless, this blog post will cover the basics with additional information covered in a downloadable webinar. Let’s start by saying that a […]

  • 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 each of the components and or sub-assemblies within the final product. But, does the current thinking […]

  • How Does Bending Affect Heat Pipe & Vapor Chamber Performance?

    The majority of applications for heat pipes, and to a lesser extent vapor chambers, require these products to be bent. Below are respective examples for high-performance graphics card, semiconductor equipment and networking applications.   But what effect does bending a heat pipe or vapor chamber have on their performance? To answer this, let’s first talk […]

  • 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 dust from […]
