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...]
The art of modelling using CFD. Part II – Grilles
Wiki quote: “A grille is an opening of several slits side by side in a wall or metal sheet or other barrier, usually to let air or water enter and/or leave but keep larger objects including people and animals in or out.” For electronic products that need to be kept cool, getting cool air in through grille work is commonplace, thermal designers love them, EMC/EMI … [Read more...]
The art of modelling using CFD. Part I – What happens if you cross art with science?
Considering that CFD (Computational Fluid Dynamics) is an advanced mathematical method for predicting fluid flow and heat transfer using a computational software approach I find it paradoxical that it is often as much an art as it is a science. A model by its very definition is a representation of something. A computer model is a virtual representation of a system (e.g. … [Read more...]
±0.5% Tolerance Chip NTC Thermistors
Murata Electronics North America added the ±0.5% tolerance option to its NCP series negative temperature coefficient (NTC) thermistor line. The ultra-tight tolerance thermistor is offered for consumer, industrial and automotive temperature ranges (-40°C to +150°C), and provides a low-cost alternative to integrated circuit (IC) based sensing solutions when high sensing accuracy … [Read more...]
Thermostatically Controlled Fan Cord
Gardtec Incorporated’s Green Fan Cord, a thermostatically controlled fan cord, allows AC fans to turn on/off as system ambient temperature calls for additional cooling. The fan cord will turn on cooling fans as ambient temperatures reach the upper 80s Fahrenheit, then turn off cooling fans as temperatures return to the lower 80s. Learn more from Gardtec Incorporated. … [Read more...]
