Probably due to the beer fridge, I now seem to be becoming the repository of broken electronic products with an expectation that the cause of their demise can be identified, retrospectively, using thermal simulation. This week my good colleague John Parry dumped a rather poorly DVD player on my desk with a ‘go on then’ look. There’s nothing quite like the sight of a scorched PCB to excite those of us working in the electronics cooling line of business here in the mechanical analysis division and that’s just what John and I found when inspecting the power supply board of this particular defunct DVD player.

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 a design that is fit for production. Trying an idea, seeing it fail, finding out why and trying a better idea next is the essence of design success.  Read the rest of this entry »

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 long for it to cool down and you might forget you wanted one, or go to sleep, or hit the whisky instead. A transient thermal simulation will tell you how long, and how evenly, the beer cools down…

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 over on to its side or even lifting it up and plonking it upside down. The door is tightly closed so why would the potential beercoolingosity in any way be affected? Let’s find out.

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. Electric coolers, fridges that utilise thermoelectric coolers (TECs) to pump the heat from inside the fridge thus keeping it cool, should therefore be more widespread as they are notoriously quiet(er). Unfortunately they are also about 6 times less efficient, requiring much more power to keep the fridge at what is known in the trade (the beer drinking trade) at beerdegreesC.

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 too polite to drink. A few weeks ago it stopped working. Some inquisitive minds and a couple of screwdrivers later it was in pieces with the conclusion that it was the thermoelectric cooler (TEC) that had given up the ghost. For a product whose raison d’etre is thermal I thought it would make a great case study in the application of FloTHERM for (retrospective) thermal design. Read the rest of this entry »

Meet Robin Bornoff

With a mechanical engineering background and CFD foundation, I have 20 years of experience in the field of electronics cooling design and simulation. Beyond my vocation I enjoy making my own cider, appreciating fractals and prime numbers, running (slowly) and will only ever read Sci-Fi.
