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.

Fabrication and characterization of microscale heat sinks
2016 22nd International Workshop on Thermal Investigations of ICs and Systems (THERMINIC), 2016In the field of thermal management, engineers are well aware of the challenges posed by the increasing level of dissipation. Among the many possible solutions to counter the threat of overheating, one is dealing with the usage of microscale heat exchangers, where the forced air or liquid cooling solution is integrated into the electronic package itself.
