RISReview and Projections of Integrated Cooling Systems for Three Dimensional Integrated Circuits
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In an effort to increase processor speeds, 3D IC architecture is being aggressively pursued by researchers and chip manufacturers. This architecture allows extremely high level of integration with enhanced electrical ...
Variable Fin Density Flow Channels for Effective Cooling and Mitigation of Temperature Nonuniformity in Three Dimensional Integrated Circuits
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The surface temperature of integrated circuit (IC) chips cooled with a singlephase liquid flow increases along the flow direction following the increase in the liquid temperature. Increasing the heat transfer coefficient ...
Mechanistic Considerations for Enhancing Flow Boiling Heat Transfer in Microchannels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Research efforts on flow boiling in microchannels were focused on stabilizing the flow during the early part of the last decade. After achieving that goal through inlet restrictors and distributed nucleation sites, the ...

A New Perspective on Heat Transfer Mechanisms and Sonic Limit in Pool Boiling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Pool boiling is postulated as a single-phase heat transfer process with nucleating bubbles providing a liquid pumping mechanism over the heater surface. This results in three fluid streams at the heater surface—outgoing ...

Intrinsic Heat Transfer Enhancement Mechanisms in Boiling With Nanoscale Surface Features
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Boiling heat transfer results from a number of multiscale phenomena that are activated by the inception of a nucleating bubble that induces motion of the liquid and vapor phases. Heat is transferred by conduction and ...
Evaluation of Pressure Drop Performance During Enhanced Flow Boiling in Open Microchannels With Tapered Manifolds
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Boiling can provide several orders of magnitude higher performance than a traditional air cooled system in electronics cooling applications. It can dissipate large quantities of heat while maintaining a low surface temperature ...
Heat Transfer Investigation of Air Flow in Microtubes—Part II: Scale and Axial Conduction Effects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the scale effects are specifically addressed by conducting experiments with air flow in different microtubes. Three stainless steel tubes of 962, 308, and 83 خ¼m inner diameter (ID) are investigated for ...
