Helical fractal heat exchanger

Abstract

A helical fractal heat exchanger comprises a heat exchanger core defining a plurality of helical, first fluid conduits arranged in a two-dimensional grid configuration, and plurality of helical, second fluid conduits in thermal communication with the first fluid conduits. A first fluid inlet structure splits a first fluid from a first fluid inlet of the heat exchanger and supplies it to each of the plurality of first fluid conduits, and a first fluid outlet structure recombines the first fluid from the plurality of first fluid conduits and conveys it to a first fluid outlet of the heat exchanger. The first fluid inlet and outlet structures are each fractal structures comprising at least two multi-furcation stages in which a parent channel divides into two or more sub-channels that diverge away from each other.
