Claim 0:
1. A heat exchanger header comprising:
a first inlet configured to be fluidically connected to a cold air system of an aircraft;
a first wall defining a first passageway, wherein the first passageway fluidically connects the first inlet to a first outlet;
a second inlet configured to be fluidically connected to a heating fluid source; and
a second wall attached to the first wall opposite the first passageway forming a second passageway between the first wall and the second wall;
wherein the second passageway that fluidically connects the second inlet to a second outlet, wherein the first inlet, the first passageway, and the first outlet are fluidically isolated from the second inlet, the second passageway, and the second outlet and the first inlet extends through both the first wall and the second wall, and wherein the second inlet extends through only the second wall;
wherein the second passageway further comprises at least one partition extending from the first wall to the second wall, wherein the at least one partition creates a channel within the second passageway that is configured to guide a flow of heating fluid from the second inlet to the second outlet when the heat exchanger header is in operation;
wherein the second passageway further comprises at least one support extending from the first wall to the second wall; and
a third wall attached to the second wall;
wherein:
the first passageway comprises a plenum adjacent to the first outlet;
the third wall is opposite the first wall; and
the second wall and the third wall define an insulating air gap between the second wall and the third wall and the insulating air gap comprises one or more fins.
