Abstract: The design of plate-fin and tube-fin crossflow heat exchangers is discussed.^The transfer surface area of crossflow heat exchangers is used ineffectively because of the nonuniform distribution of the heat transfer across the volume of the exchanger.^The optimal distribution of the transfer surface area for maximum heat exchanger effectiveness and constant total surface area is determined.^It is found that a Dirac delta distribution of the transfer surface aligned along the diagonal of the crossflow exchanger gives the best performance; equal to that of a counterflow device.^Design guidelines for optimal area allocation within crossflow heat exchangers are established.^Compared to conventional designs, designs following these guidelines may lead to either a higher exchanger effectiveness for equal pressure drops and surface area, reduced pressure drops for equal exchanger effectiveness, or reduced weight and a near cubic form of the exchanger core for equal pressure drops and effectiveness.
