The conceptual design and performance of balanced two-stream counterflow heat exchangers was discussed. The relationships between effectiveness and number of heat transfer units for several tree-counterflow configurations were developed. It was found that the longitudinal temperature gradient in the counterflow formed by two trees was steeper as one approaches the periphery of the tree canopy. The application of dendritic heat exchangers to devices with maximal transport density was also discussed.
