  • Electrical Considerations of Fan Cooling
    on. an integrated heat sink and fan to provide adequate cooling for the amplifier. The standard fan supplied with the amplifiers is a 12V brushless DC motor. fan. Like all switching circuits the brushless motor commutation generates. electrical noise. If care is not taken in how the fan is connected
  • Cooling High-Density Open-Fram DC/DC Converters
    increases so does the power dissipation inside the converter and unless the efficiency approaches 99% (not in the near future), the system designer must apply the same cooling techniques for DC/DC converters as one would for any power transistor such as TO-3 220, etc
  • Intelligent Thermal Management Using Brushless DC Fans
    The brushless DC fan (BDC Fan) has become the air mover of choice in computing equipment, office automation products, home entertainment systems, and the like. Unlike conventional DC fans, the BDC fan is mechanically robust because it contains no rotating commutator/brush assembly to shed dust
  • Cooling Industrial Enclosures with Filter Fans (.pdf)
    . with Filter Fans. R. Cooling Industrial Enclosures with Filter Fans. Mark Madden. Table of Contents. Executive Summary ......................................... Page 3. Introduction ...................................................... Page 4. When to Use a Filter Fan
  • Cooling Systems for Electronic Enclosures
    . . telluride. Upon application of a direct current (DC). power source, the device transfers heat from one side. to the other. The side that heat is taken from becomes. cold. With the right packaging, the cooling properties. of these devices can be harnessed
  • Cooling Power Op Amps
    to a similar amplifier cooled with a passive heat sink. Utilizing a small DC fan to force air into the heat sink the PAD117 provides a. 0.5OC/Watt thermal resistance for the amplifier's substrate with a volume of. only 4.6 in3 and a weight of 4 oz. Aavid/Thermolloy has a passive heat sink. extrusion
  • DC Fans - Sealed Bearing System
    PTI's revolutionary new Sealed Bearing System; the high performance/low cost environmental DC fan bearing solution. Ball and sleeve bearings are used extensively in DC fan manufacturing to provide effective cooling solutions for a variety of industries. However, each has advantages
  • 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
