| Abstract | ||
| There has been deep interest by research workers in the thermal characteristics of heat sinks as cooling devices in certain engineering systems (e.g. computer microprocessors and motherboards). The main emphasis has been on how to enhance the heat transfer rate from such cooling devices. Finned surfaces were one obvious solution in this case. Vapor chamber heat sinks may also be another solution. This paper gives an over view of up-to-date published research in the area of flat plate type heat sinks provided with fins. Some 40 articles were reviewed and examined, covering various aspects of the subject. Each article was critically evaluated. Aspects requiring further work and deeper insight were spotted, drawing attention to their importance. Suggestions for possible means thought to augment the heat transfer rate of heat sinks were postulated. | ||
