Abstract
A heat exchanger includes a wall that has a first end, a second end, a first side that bounds a chamber, and a second side opposite the first side. The first side and the second side extend from the first end to the second end. The wall defines a length direction from the first end to the second end. There is an array of cooling channels embedded in the wall to convey a cooling fluid. Each of the cooling channels defines a flowpath that has a varying circumferential curvature relative an axial direction.
Claims18
A heat exchanger comprising:
- a wall disposed about a central axis and having a first end, a second end, a first side bounding a chamber, and a second side opposite the first side, the first side and the second side extending from the first end to the second end;
- and
- an array of cooling channels embedded in the wall to convey a cooling fluid, each of the cooling channels defining a flowpath that has a varying circumferential curvature relative an axial direction.
An article comprising:
- a nozzle formed of a wall disposed about a central axis and circumscribing a chamber, the wall having a first axial end, a second axial end, an inner side bounding the chamber, and an outer side opposite the inner side,
- an array of cooling channels embedded in the wall to convey a cooling fluid in the wall, each of the cooling channels defining a flowpath that has a varying circumferential curvature relative an axial direction.
