Abstract
A heat exchanger includes a heat exchanger wall that bounds a passage. A coating lines the heat exchanger wall. The coating has a thickness that varies according to location on the heat exchanger wall.
Claims13
A heat exchanger comprising:
- a first plate;
- a second plate;
- a heat exchanger wall bounding a passage, wherein the wall is a fin separating the first plate and the second plate;
- and
- a coating lining the heat exchanger wall, the coating having a thickness that varies according to location on the heat exchanger wall,
- wherein the heat exchanger wall has an edge and a location spaced from the edge,
- the coating is thicker at the edge than at the location spaced from the edge, wherein the coating has a maximum thickness of T1 and a minimum thickness of T2 such that a ratio of T1/T2 (T1 divided by T2) is equal to or greater than 2, and
- the edge is a leading edge with respect to the passage being arranged to receive a flow of a fluid.

A heat exchanger comprising:
- a first plate;
- a second plate;
- an inlet face arranged to receive ram air;
- an exit face opposed from the inlet face;
- a plurality of heat exchanger walls extending between the inlet face and the exit face, the plurality of heat exchanger walls defining a plurality of passages that open at respective leading edges at the inlet face and at respective trailing edges at the exit face, wherein the plurality of heat exchanger walls are fins separating the first plate and the second plate;
- and
- a coating lining the plurality of heat exchanger walls, the coating having a thickness that varies according to location on the plurality of heat exchanger walls, wherein the coating has a maximum thickness at the leading edges, wherein the coating has a maximum thickness of T1 and a minimum thickness of T2 such that a ratio of T1/T2 (T1 divided by T2) is equal to or greater than 2.
