  • 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
  • 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

  • A fan of fuel savings
    control of a 20-hp fan (typical of a light truck) saves more than 200 gallons of fuel over 10,000 miles compared with the same sized direct-drive fan. It saved over 50 gallons compared with a viscous-coupled fan. And truck and bus maker Navistar says on-off cooling fans may save operators of its
  • Are Hydraulic Fan Drives For You?
    engine speed, not cooling demand. This means belt-driven fans usually deliver too high or too low an air flow, which not only causes wide fluctuations in engine temperature, but wastes power. Maximum power is lost when the engine (fan) runs at high speed, even though little cooling may be needed
  • Tilt the modules and shrink the fans, says thermal software
    The whole point of simulation software is to test ideas on the fringe. Even tightly packed control rooms show sufficient cooling for each cabinet. The Honeywell Experion R300 system has over 30 process-control I/O and controller modules stacked in columns. Stacking modules at an 18 tilt directs
