For aviation platforms, the goal is to design the most high performance and lightweight systems that exceed the required reliability standards. Military aircraft often emphasize mission capability as the key objective, while commercial aircraft emphasize Specific Fuel Consumption (SFC) and overall life-cycle costs. Traditionally mechanical, hydraulic, and pneumatic drive … [Read more...]
Reasons to Use Two-Phase Refrigerant Cooling
Water-cooling at the rack appears to be the new short-term technological solution for server cooling in datacenters, with its advantages over traditional cold aisle/hot aisle air-cooling being clear, as can be seen in [1]. Bringing chilled water to the rack and then cooling the air inside the rack aids with the transport of energy across the datacenter, making the necessity for … [Read more...]
Beer Fridge – A Case Study in Thermal Design. Part 6 – Baffles and Bottlenecks
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, … [Read more...]
Beer Fridge – A Case Study in Thermal Design. Part 5 – Time for a FloBEER
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 … [Read more...]
Beer Fridge – A Case Study in Thermal Design. Part 4 – FloBEER
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 in FloTHERM, in fact when … [Read more...]
