Evolutionary design with freedom-Fin shapes and entrance length channels for heat sinks

The new direction traced in this article is to vary freely and simultaneously the fin and flow channel aspect ratios in the search for the complete high-density heat transfer flow architecture. We show that when the combined solid and fluid volume is specified, and the fluid flow rate is known, it is possible to anticipate from theory the complete design (all the aspect ratios) of the flow configuration. The power to predict covers the overall heat transfer rate and the required pumping power. The configuration and performance owe their existence to the multiple degrees of freedom identified in the design, and exploited in the theory.

Automated summary

The article proposes a new approach of freely varying the aspect ratios of fins and flow channels simultaneously to achieve a complete high-density heat transfer flow architecture. It demonstrates that by specifying the combined solid and fluid volume and knowing the fluid flow rate, it is possible to predict the complete design of the flow configuration, including all aspect ratios, based on theory. The prediction power encompasses the overall heat transfer rate and required pumping power. The existence and performance of the design owe to the multiple degrees of freedom identified and utilized in the theory.
