Methods and apparatus to generate oscillating fluid flows in heat exchangers

Abstract:

Methods and apparatus to generate oscillating fluid flows in heat exchangers are disclosed. A disclosed fluid flow apparatus includes a repeating pattern of fins arranged in rows, where fins of each row are separated from one another by channels, where the fins have respective sub-channels extending therethrough to facilitate oscillation of fluid moving through the channels, and where each of the sub-channels defines a sub-channel inlet and a sub-channel outlet of a respective fin of the pattern.
