Introduction Telecommunication satellites are all based on the same overall design usinga 3 axis stabilization process, in which the North and South panels act asradiators and so ensure heat removal. This basic principle is illustrated in Figure 1. The ever-increasing demandfor national and international space-based communications in parallel with theevolution of space … [Read more...]
Heat Pipes for Electronics Cooling Applications
Figure 1: Heat pipe operation Introduction All electronic components, from microprocessors to high end powerconverters, generate heat and rejection of this heat is necessary for theiroptimum and reliable operation. As electronic design allows higher throughputin smaller packages, dissipating the heat load becomes a critical design factor. Many of today's electronic devices … [Read more...]
An introduction to thermoelectric coolers
Figure 1: Cross Section of a Typical TECouple Introduction Thermoelectric coolers are solid state heat pumps used in applications wheretemperature stabilization, temperature cycling, or cooling below ambient arerequired. There are many products using thermoelectric coolers, including CCDcameras (charge coupled device), laser diodes, microprocessors, blood analyzersand portable … [Read more...]
Thermoelectric thermal regulation systems
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- and hyperthermia. Thermoelectric coolers (TECs) are essentially solid state devices that … [Read more...]
Minimizing acoustical noise in electronic systems
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 for the description of noise, design guidelines for theselection of low noise air movers, upper limits for the noise … [Read more...]
