Classification: CPC B  F | IPC B  F

Claim 12:
13. An aerospace vehicle comprising:
a vehicle body;
an engine connected to the vehicle body and configured to power the vehicle body in a flight mode; and
a heat transfer device connected to the vehicle body and/or the engine and including
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 helical fluid channels of each first channel layer, for flow of a first fluid through the heat transfer 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 a second fluid through the heat transfer 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.
