Abstract
A heat transfer arrangement includes two or more heat transfer cells. The heat transfer cells together define a boundary between a higher temperature region and a lower temperature region. Each of the two or more heat transfer cells includes two or more walls defining a fluid tight cavity. One or more wick is fused to an inner surface of one or more of the walls to wick liquid from a lower temperature portion of the cavity to a higher temperature portion of the cavity. Combustors having heat transfer arrangements with heat transfer cells and methods of making heat transfer arrangements are also described.
Claims6
A method of making a heat transfer arrangement, comprising:
- densely sintering a first portion of a powdered material to form a plurality of walls that define a fluid tight cavity of a heat transfer cell;
- and
- porously sintering a second portion of the powdered material to form a wick fused to at least one of the plurality of walls.
