  • Cooling Industrial Enclosures with Filter Fans (.pdf)
    to this conclusion are covered. Cooling Industrial Enclosures with Filter Fans. 3. Introduction. As electronic components get smaller and more densely packed into enclosures, systems are becoming. increasingly sensitive to external factors including dust, oil, and temperature. Heat in particular
  • Cooling the pin-fin way
    Pin-fin heat sinks offer lot of cooling in a small package. Pin-fin heat sinks come in a wide variety of footprints, pin densities, thicknesses, and heights. They can dissipate up to 185 W in a volume less than 6.3 in. with the help of a small fan. Increasing the processing power of electronic
  • Cooling with Augmented Heated and Cooled Seats (.pdf)
    . consists of Peltier element or thermoelectric module with. a fan embedded in the seat. These units typically consist. Heating and cooling automotive seats are a relatively. of one or more thermoelectric (TE) modules, heat. new technology that delivers conditioned air to the. exchangers, and fans
  • Integrated cooling system lets chips beat the heat
    Ever-increasing power density in highperformance ICs has pushed the limits of conventional cooling methods such as heat sinks and fans. But a technique that puts liquid-cooling channels onto the backs of ICs could significantly boost cooling rates and make 3D chips more practical, say developers
  • Fans With Integrated Control and Monitoring: Intelligent Equipment Cooling - the Right Dose of Air (.pdf)
    . With this type of temperature-dependent fan control, the. speed drops when the thermal load is low and in turn the noise emission. It is also easy to integrate. speed-controlled fans in the overall configuration. Programmable cooling, cooling on request and. dialog ability are further important catchwords
  • 4-20 mA Vibration Monitoring of Chillers and Cooling Units
    ®). Monitoring fans running above 300 RPM. Small cooling cells and many HVAC cooling system fans will have fan speeds over 300. RPM. Where fans speeds exceed 300 RPM, the LPS® work well. Dynamic vibration. data is converted to a 4-20 mA signal within the sensor housing and output directly to a. PLC
  • Understanding Electronic Motor Drives
    for cooling airflow) or NEMA 12 (sealed, dust-tight enclosure). NEMA-1 drives are susceptible to dust contamination. Dust on hardware can restrict airflow, degrading performance from heat sinks and circulating fans. Dust on electronic devices can cause malfunction or failure. Dust absorbs moisture
  • Electronic Motor Diagnostics
    of motor current signature analysis (MCSA). One of the more complex systems to test is the AC salient pole alternator, which we will refer to as a generator for the purposes of this paper.
