Abstract: Heat-sink with air-cooling fan is the simplest and the most effective way to disperse generated heat of a high-tech device. A common approach to optimize heat sinks is based on the minimization of the entropy generation rate that takes the two major heat dissipation factors, heat transfer rate and air resistance, into consideration. However, a lower entropy generation rate often corresponds to a larger size of the designed heat sink. To have a balance design of heat sinks for heat dissipation, this paper considers the simultaneously minimization of the entropy generation rate and the material cost of the heat sinks. A multi-objective real-coded genetic algorithm using a novel direction-based crossover operator is developed for the formulated optimal heat sink design problem. With the proposed design framework, we compare and evaluate the performance of the plate-fins equipped with flow-through and impingement-flow air cooling systems. Extensive simulation results show that the balance design for heat sinks can achieve both the benefits of light weight and excellent heat dissipation.

A fast and elitist multiobjective genetic algorithm: NSGA-II
TL;DR: This paper suggests a non-dominated sorting-based MOEA, called NSGA-II (Non-dominated Sorting Genetic Algorithm II), which alleviates all of the above three difficulties, and modify the definition of dominance in order to solve constrained multi-objective problems efficiently.
Compact heat exchangers
TL;DR: The third edition of the second edition as discussed by the authors was published in 1964 and contains basic test data for eleven new surface configurations, including some of the very compact ceramic matrices, in both the English and the Systeme International (SI) system of units.

Entropy generation through heat and fluid flow
Adrian Bejan
- 01 Jan 1982
Abstract: The first textbook to bridge the gap between three cornerstones of engineering education: fluid mechanics, thermodynamics and heat transfer. It provides an effective method to teach the thermodynamic (second law) aspects of heat and fluid flow processes, and shows how to use such processes in the design of energy-efficient devices. The text offers a wide range of original research to support the entropy generation minimazation'' philosophy and includes 250 references in the field of thermodynamic optimization and the thermodynamics of heat and fluid flow.
