Methods are presented for evaluating the performances of compact surfaces based on their simultaneous heat transfer rates and pumping power expenditures. Calculations of approximate total costs and volume requirements for a heat exchanger are simplified with the aid of performance curves based on a unit of heat transfer surface area and a unit of exchanger volume. In certain cases, the minimum cost surface can be determined from a single plot and requires no specific cost information. Basic design data are presented for three plate-fin surfaces, each one having a different degree of heat transfer promotion. The attractiveness of each type of surface is shown to depend on the particular design specifications.
