Thermal Design Perfection Starts with the use of FloTHERM PACK

April 8th, 2011

‘Plagiarism saves time’ as can be seen in the title of this blog, a nod to Tom Hausherr’s excellent blog series, particularly Part 15 that focuses on QFNs. Whereas the internal construction of a package is of little interest when defining CAD library symbols, from a thermal simulation perspective they are absolutely critical. FloTHERM PACK can [...]

We Love FloTHERM V9.2

April 7th, 2011

FloTHERM, and its sister product FloVENT, have been going since 1989. Many in the Mechanical Analysis Division in Mentor have been working on these products for that time, personally I’m up to 15 years. It’s testament to the products and their success that our passion for them continues unabated. V9.2 was released this week, the [...]

Desktop PC with Integrated Toaster – the Future is Now

April 1st, 2011

The convergence of technology platforms continues apace, especially in the mobile telephony world. The world of overclockers and case modders isn’t standing still either. For the bargain price of $29.99 you can bag yourself a 5.25 inch bay toaster from CrazyPC.com. The wonderful dichotomy of having a system that requires both electronics thermal cooling and benefits from [...]

Do you know the way to San Jose?

March 18th, 2011

One of the highlights of the electronics thermal management calender is the annual SEMI-THERM symposium held in sunny San Jose, California and it’s with the usual sense of excitement that I’m preparing to attend it. The acquisition of Flomerics by Mentor Graphics was two and half years ago and, despite the expectations of many, the [...]

Beer Fridge – A Case Study in Thermal Design. Part 6 – Baffles and Bottlenecks

February 14th, 2011

For a blog series focused on thermal design there has been precious little design presented so far. Design is the process of making a plan for the construction of an object/product. Whether you subscribe to the rational or action-centric model of the design process, some form of iteration and adaption is used to arrive at [...]

Beer Fridge – A Case Study in Thermal Design. Part 5 – Time for a FloBEER

January 27th, 2011

All good things come to those who wait. For beer this entails a trade off between anticipation and satisfaction. If, too soon after you put the room temperature beer in the fridge, you get your child to grab a beer for you, your thirst might be quenched but your satisfaction might not be. Wait too [...]

Beer Fridge – A Case Study in Thermal Design. Part 4 – FloBEER

January 7th, 2011

As the ancient proverb goes; a beer fridge without beer is like X Factor, utterly pointless. You’d have thought that by clogging up the insides of the fridge with pesky cans of beer you’d cripple it’s thermal performance. As someone once said of Simon Cowell …”O, how wrong you are”.
When modelling a can of beer [...]

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 [...]

We Love FloTHERM – 8 Reasons to Upgrade to V9.1

November 5th, 2010

Here at the Mechanical Analysis Department we love FloTHERM and we love developing FloTHERM to ensure it keeps up with the needs and follows the trends of the electronic thermal simulation market. The latest release of FloTHERM, V9.1, has a wealth of features and benefits that continues to ensure it’s position as the #1 CFD based [...]

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 [...]
