Conventional heat sinks for processors achieve improved heat transfer efficiency by impinging ambient air over stationary fins. Further improvement in the air film heat transfer coefficient through increased air speed becomes asymptotic and invariably results in undesirable acoustic noise.

Characterization of Heat Sink Flow Bypass in Plate Fin Heat Sinks
Heat Transfer, Volume 5, 2002Experimental testing has been performed on two plate fin heat sinks in order to examine flow bypass phenomenon. The present study examines pressure drop and thermal resistance as well as flow velocities within the heat sinks. Tests are performed for bypass channel/fin height ratios of 0.25, 0.5, 0.75 and 1 with approach velocities from 2 to 8 m/s.

A method to rank heat sinks in practice: the heat sink performance tester
Semiconductor Thermal Measurement and Management IEEE Twenty First Annual IEEE Symposium, 2005., 2005One way of cooling electronic devices is through enlarging the surface that is in contact with a fluid (usually air) by attaching a heat sink. Since literally thousands of heat sinks are available many designers are confronted with the question: which one? Very often the designer's choice is based on cost and manufacturer's data.

Optimization of heat sink fin geometries for heat sinks in natural convection
[1992 Proceedings] Intersociety Conference on Thermal Phenomena in Electronic Systems, 2003An approach for determining the optimum fin configurations for a given heat sink in natural convection is developed. Incorporation of minimization routines into the analysis eliminates the manual, iterative design analysis and identifies the optimum design. Optimization of fin geometry for heat sinks in natural convection with rectangular cross section

Thermal comparison of plate, extrusion heat sink, and skive heat sink
Seventeenth Annual IEEE Semiconductor Thermal Measurement and Management Symposium (Cat. No.01CH37189), 2002Due to the high power dissipation values of power amplifiers, large temperature gradients exist, resulting in localized hot spots around the devices. These hot spots cause high device junction temperatures. Generally speaking, the higher junction temperature increases, the lower reliability will be. Thus, improving the heat spreading is very important.

This paper explains the bases for the design of a heat-sink module, a module desirable because of its great flexibility in component arrangement and adaptability to new usages. The methods by which the module would meet major design problems, such as heat management, standardization and internal flexibility, and component interconnection, are outlined,

Thin vapor chamber heat sink and embedded heat pipe heat sink performance evaluations
2009 25th Annual IEEE Semiconductor Thermal Measurement and Management Symposium, 2009Vapor chamber and heat pipe technologies are not new concepts, but their fabrication and manufacturing processes have been improving. Both vapor chambers and heat pipes have been getting thinner allowing the integrated heat sink design with increased fin surfaces. For example, for vapor chambers, the minimum achievable thickness has been reduced from 5

Optimization of convectively cooled heat sinks
Microelectronics Reliability, 2017Abstract Many factors of heat sink, such as its size and mass, component locations, number of fins, and fan power affect heat transfer. Owing to the opposite effects of these factors on heat sink maximum temperature, we have now a multi-objective optimization problem.

Micro-Heat-Sinks for Space Applications
ASME 2nd International Conference on Microchannels and Minichannels, 2004During the space missions, the problems related to the thermal conditioning of devices, to the personnel comfort and to the thermo-mechanical stresses are known and important. Furthermore for a space mission certain priorities are stressed, such as the small dimension and the lightness of thermal equipments.
