1. A device for transferring heat between a first fluid and a second fluid, the device comprising:
a set of nested tubular walls;
a plurality of helical walls intersecting each of the nested tubular walls to form one or more first channel layers nested with one or more second channel layers, each first channel layer and each second channel layer including a plurality of helical fluid channels;
a first intake and a first outtake in fluid communication with one another via the plurality of helical fluid channels of each first channel layer, for flow of the first fluid through the device from the first intake to the first outtake; and
a second intake and a second outtake in fluid communication with one another via the plurality of helical fluid channels of each second channel layer, for flow of the second fluid through the device from the second intake to the second outtake, wherein each of the plurality of helical walls extends radially outward, linearly, in a plane including a central axis of the device.
