Beer Fridge – A Case Study in Thermal Design. Part 3 – Side Up or Upside Down?

January 4th, 2011

The futility of investigating the cooling effectiveness of any empty fridge is beginning to dawn on me, the irony of which is matched only by my new-years-resolution-inspired-sobriety. Never mind, let’s see this particular study through…  Whether in a beer ridden fury or in moments of Galilean scientific investigation, you might find yourself kicking the fridge […]

Beer Fridge – A Case Study in Thermal Design. Part 2 – TEC Effect

December 21st, 2010

Beer drinkers are notoriously quiet people and as such would not want to be disturbed by the continuous hissing and whirring of a classic compression/expansion refrigeration cycle type beer fridge. They would argue that’s why both kids and kitchens were invented. Kitchens to put the noisy fridge in, kids to go get the next beer. […]

Beer Fridge – A Case Study in Thermal Design. Part 1 – A Gift

November 26th, 2010

My boss, Roland, relocated from Germany to the UK a couple of years ago and has taken to life in England with alacrity. As a gift for the Mechanical Analysis product development department (Hampton Court) he bought a little fridge which has been busy ever since cooling the beer in it that everyone has been […]

What Can You Learn When You Turn It On?

November 19th, 2010

Power on an IC package, measure the resulting transient response of the junction temperature and from that infer a wealth of information about the structure of the package that the heat has to flow through. Such a methodology is at the heart of the Mechanical Analysis Division’s T3Ster(pronounced “trister”) product. Some simulation software vendors pitch […]

Identifying Thermal Bottlenecks and Shortcut Opportunities – Taking Simulation to the Next Level

October 27th, 2010

Simulation has, to date, focused primarily on the prediction of an operating state that is compared to a design acceptable state to judge the compliance of that design. From an electronics cooling perspective that state is often taken as the operating temperature of packaged ICs, most commonly a case (Tc) or junction (Tj) temperature. FloTHERM has, over […]

Lies, Damned Lies, and “CFD Comparison Charts” – Part II

August 12th, 2010

In my last post I pointed out a very obvious mistake in Blue Ridge Numerics’ “CFD Comparison Chart” of March 19th this year, which incorrectly stated that FloEFD can only handle incompressible sub-sonic flows.
The reason I highlighted this as the most obvious mistake in the “CFD Comparison Chart” is that FloEFD can trace its history […]

How many frogs does a horse have?

August 10th, 2010

The internet is big. It’s not sentient yet, though Robert Swayer has written a compelling story of how it might ‘Wake‘. In fact it’s far from intelligent at all. Banal comments about “how we ever managed without it” will age so quickly that future historians will assume a typo, more intelligence than we currently have and […]

An Interview With… Clemens Lasance

July 27th, 2010

Every industry or industry sub-sector has its movers and shakers, its pioneers and thought leaders. These people have likely helped shape and evolve that industry to what it is today and what it may become in the future. For this series of ‘An Interview With…’ blog posts I will be posing the same set of questions […]

Mechanical Analysis Products Now in Mentor’s Higher Education Program

July 19th, 2010

If you’re involved in CFD in education in any way this will be of interest to you. Since shortly after Flomerics were acquired by Mentor Graphics we’ve been working towards getting out products into Mentor’s Higher Education Program (HEP), and we’ve finally got it done.
To my knowledge, the availability of potentially millions of dollars worth […]

Red Hot Electronic Thermal Analysis?

July 14th, 2010

The etymology of the phrase ‘red hot’ dates back to the 14th century describing the colour attained by metal as it is heated. When attributed to people it can euphemistically be used to describe passion and attractiveness. Any colourful picture output from a numerical thermal simulation of an electronics system will have red depicting hot and […]

Sony Vaio laptop in mass ‘recall’

July 1st, 2010

“Authorities in the US have instructed Sony to conduct a recall of its Vaio laptops, after problems with overheating were reported.” started this article on the BBC’s web site.
There is a saying, ” the news is never as good or as bad as it is first reported”. And so it is with this story. It’s not […]

The art of modelling using CFD. Part VI – Peripheral Boundary Conditions

June 21st, 2010

This final blog in this series focuses on what is sometimes the most ethereal of CFD modelling arts, where and how to define your peripheral boundary conditions. A fancy phrase but in reality no more than deciding where the interface is between what you model and what you don’t. Heat is contemptuous of such divisions, […]

Nearly Back to Business as Usual

June 4th, 2010

I’ve not posted for a while, which is rather remiss of me. I underestimated the response we would get to our Heatsink 201 webinar, which I gather was our most popular ever, and the number of questions that people would ask. I had around 120 questions, which after removing duplicates and those to do with […]
