  • A fundamentally new approach to air-cooled heat exchangers.
    For example, state-of-the-art CPU coolers providing thermal resistances as low as 0.2 C/W are not only very large devices unsuitable for mass market applications, but in addition are prohibitively expensive.
  • Selection and Evaluation of Thermal Interface Materials for Reduction of the Thermal Contact Resistance of Thermoelectric Generators
    resistance.1–7 The TIM fills the air gap and, because its thermal conductivity is greater than that of air, the thermal contact resistance is lower . .... For this reason, TIMs are widely used for such electronic devices as Bi-Te TEGs and central processing unit ( CPU ) coolers , which both need rapid thermal drains.
  • CR4 - Blog Entry: Recovering from a watercooling leak
    The lower the resistance , the more heat a system removes at a given ambient temperature. .... Typically, a stock heatsink/fan CPU cooler has a thermal resistance around 0.4 to 0.5 deg C/W.
  • Hybrid thermoelectric conversion for enhanced efficiency in mobile platforms
    Upper and lower limits of the shunt thermal resistance were chosen based on equation (3), . hp-a from table 1, and various CPU TDP values. .... though peak power consumption is high (figure 13) when the TE is in cooler mode, the average…
  • Thermal characterization of a fan-sink for an AGP card
    Sun, Thermal Characterization of a Fan-sink for an .... volume resistance result is 24% lower than that of the previously mentioned start-of-art CPU cooler .
  • The Thesis Committee for Hyunji Lim
    On the heat sink side is a low thermal resistance , typically less than 0.5C/W, whereas on the cooling side the thermal resistance is typically an order of magnitude greater. .... To dissipate heat accumulated in the hot plate of the Peltier cooler , a CPU heat sink (copper, 82 (L) x 65 (W) x 37.5 (H) mm) was interfaced to the hot plate of the Peltier cooler.
  • Asus Motherboard - Techist - All Things Tech
    My CPU always runs mysteriously hot though, even with a zalman aftermarket cooler . .... A thinner layer of thermal paste is recommended. .... It will lower the contact resistance between the mating surfaces.
  • :: New Materials Zone ::
    Patent-pending techniques allow a further cell-density increase, which lowers on- resistance while maintaining switching performance. .... The four WFET power MOSFETs released today are designed to provide efficient high-side operation - running cooler or handling higher output current with the same efficiency, in notebook CPU core dc-to-dc converters in single- and multi-phase configurations with a .... TheSi4390DYand Si4392DYare offered in the LITTLE FOOT SO-8 and, for improved thermal performance, the Si7390DP and…
  • Thermal management of electrical overload cases using thermo-electric modules and phase change buffer techniques: Simulation, technology and testing
    As the heat removal benefits from lower thermal resistances and also higher operation temperatures (thinking of convection as the final heat removal or heat sink), novel high-temperature joining processes (i.e. TLPS/TLPB and sinter silver) and double­ sided cooling assembling are .... Heat pipes for examples (commonly embedded into today's CPU coolers or notebooks) are of high interest, providing possibilities to enhance heat spreading or transfer.
  • Electromagnetically-driven ultra-fast tool servos for diamond turning
    The selected cooler obviously has the advantage of both high conductivity and high fin density, as well as relatively low unit cost. .... A total of 9 CPU coolers are sufficient for the power amplifier as illustrated by the thermal model in Figure 5-3. .... a heat source of Is = 250 W, and its junction-to-package thermal resistance is Rt = 0…
