Orion Fans has expanded its line of fan accessories with the LFG120B and LFG172B louvered fan guards. These heavy-duty filtered units help prevent dust and dirt from entering enclosures such as industrial cabinets, server cabinets and server racks. The fan guards also protect fingers from injury by the fan blades. Available for 120mm and 172mm fan sizes, the louvered fan guards … [Read more...]
Ultra-Green CPU Cooling Technology
NEC has developed an eco-friendly cooling system for CPUs, said to use 60% less energy than a water-cooling system and even 80% less than an air-cooling system. The core of the system is a liquid chlorofluorocarbon (CFC) substitute, which circulates around the CPU to draw away heat and has low greenhouse effects. NEC says the refrigerant begins boiling at around 50oC, changes … [Read more...]
Compact Water-Circulation System Prevents Stacks of Electronic Chips
A research team from the A*STAR Institute of Microelectronics and Nanyang University in Singapore has designed and built a water circulation system to cool stacks of integrated electrical circuits. “The heat must be removed from microchips to maintain a temperature within acceptable limits: less than 100 °C,” explains team-member Navas Khan from the Institute of … [Read more...]
The art of modelling using CFD. Part IV – Fans
Sometimes the ability to apply artistic interpretation of your virtual product to your simulation model of it is limited or dictated (take your pick) by the available capabilities of that simulation tool. CFD simulation is quite a young technology, application to electronics cooling newer still, a mere 21 years old. Always pushing the limit of available computing resource, … [Read more...]
The art of modelling using CFD. Part III – TIGs
Never trust a TLA (three-letter acronym) or those who use them, unless the abbreviation provides some value in terms of repetitive usage or is accepted as an industry standard. Too often TLAs are used as a screen between those who are listening and the incompetence of the person talking. TIGs (thermally insignificant geometries) as a TLA is neither useful nor accepted, I just … [Read more...]
