All you need to know about fans

May 1st, 1996

A Basic Fan/Blower Description Fans can be thought of as low pressure air pumps that utilize power from amotor to output a volumetric flow of air at a given pressure. A propellerconverts torque from the…read more

Direct liquid immersion cooling for high power density microelectronics

May 1st, 1996

Introduction Since the development of the first electronic computers in the 1940s, thedevelopment of faster and denser circuit technologies and packages has beenaccompanied by increasing heat fluxes at the chip and package levels. Over theyears,…read more

How to evaluate fan life

May 1st, 1996

Convection air cooling is still the most commonly used method of coolingmicroelectronics. In order to deliver air cooled computer equipment with higherreliability, we need to focus on the life expectancy of the air moving devices(AMDs).…read more

Minimizing acoustical noise in electronic systems

May 1st, 1996

Introduction Air-moving devices (AMDs), such as fans and blowers used for cooling inelectronic systems invariably generate acoustical noise which must be consideredif people are exposed to the emitted noise. In this article, we discussquantitative measures…read more

Thermoelectric thermal regulation systems

May 1st, 1996

Thermoelectric temperature control systems are being used in an increasingnumber of applications. Typical applications of these systems are in thermalregulation of electronic enclosures, recirculating chillers for laser cooling,semiconductor process control and management of patient hypo-…read more
