The first side panel has a first side panel first portion, a first side panel second portion, and a first side panel arcuate portion. The second side panel has a second side panel first portion, a second side panel second portion, and a second side panel arcuate portion. The front panel extends between the first side panel first end and the second side panel first end. The front panel includes a front panel first end that abuts the first side panel first end and a front panel second end that abuts the second side panel first end. ## Claims ### Claim 1 A heat exchanger assembly for an environmental control system, comprising: an inlet header arranged to receive a first fluid that flows along a first axis; a primary heat exchanger arranged to receive a second fluid that flows along a second axis that is disposed transverse to the first axis, the primary heat exchanger arranged such that the first fluid flows through the primary heat exchanger along the first axis; and an outlet header operatively connected to the primary heat exchanger and arranged to exhaust the first fluid, the outlet header comprising: a first side panel having a first side panel first portion, a first side panel second portion, and a first side panel arcuate portion extending between the first side panel first portion and the first side panel second portion along the first axis, and a second side panel spaced apart from the first side panel, the second side panel having a second side panel first portion, a second side panel second portion, and a second side panel arcuate portion extending between the second side panel first portion and the second side panel second portion; wherein: the first side panel first portion, the first side panel second portion, and the first side panel arcuate portion extends from a first side panel first end towards a first side panel second end along the second axis; the second side panel first portion, the second side panel second portion, and the second side panel arcuate portion extends from a second side panel first end towards a second side panel second end along the second axis; the assembly further comprises a front panel extending between a front panel first end and a front panel second end, wherein the front panel first end is connected to the first side panel first end and the front panel second end is connected to the second side panel first end; the front panel first end and the first side panel first end define a first arcuate corner of the outlet header; and the front panel second end and the second side panel first end define a second arcuate corner of the outlet header. ### Claim 2 (depends on 1) The heat exchanger assembly of claim 1, wherein a first width is measured between the first side panel first portion and the second side panel first portion, a second width is measured between the first side panel second portion and the second side panel second portion, and a third width is measured between the first side panel arcuate portion and the second side panel arcuate portion. ### Claim 3 (depends on 2) The heat exchanger assembly of claim 2, wherein the third width is greater than at least one of the first width and the second width. ### Claim 4 (depends on 1) The heat exchanger assembly of claim 1, wherein the first side panel first portion and the first side panel second portion are disposed parallel to the first axis and the first side panel arcuate portion is disposed in a nonparallel relationship with the first axis. ### Claim 5 (depends on 1) The heat exchanger assembly of claim 1, wherein the second side panel first portion and the first side panel second portion are disposed parallel to the first axis and the second side panel arcuate portion is disposed in a nonparallel relationship with the first axis. ### Claim 6 (depends on 1) The heat exchanger assembly of claim 1, further comprising: a rear panel disposed opposite the front panel and extending between the first side panel second end and the second side panel second end. ### Claim 7 (depends on 6) The heat exchanger assembly of claim 6, wherein the front panel, the rear panel, the first side panel, and the second side panel define a first outlet. ### Claim 8 (depends on 7) The heat exchanger assembly of claim 7, wherein the outlet header further comprising: a second outlet separated from the first outlet by the rear panel. ### Claim 9 (depends on 7) The heat exchanger assembly of claim 7, further comprising: a secondary heat exchanger operatively connected to the primary heat exchanger and the inlet header, the secondary heat exchanger arranged to receive the second fluid such that second fluid flows through the secondary heat exchanger in a direction that is disposed substantially parallel to the second axis. ### Claim 10 A heat exchanger assembly, comprising: an outlet header having a first outlet and a second outlet spaced apart from the first outlet, the first outlet comprising: a first side panel having a first side panel first portion, a first side panel second portion, and a first side panel arcuate portion extending between the first side panel first portion and the first side panel second portion along a first axis, each first side panel portion extending from a first side panel first end towards a first side panel second end along a second axis, a second side panel having a second side panel first portion, a second side panel second portion, and a second side panel arcuate portion extending between the second side panel first portion and the second side panel second portion along the first axis, each second side panel portion extending from a second side panel first end towards a second side panel second end along the second axis, and a front panel extending between the first side panel first end and the second side panel first end; wherein: the front panel includes a front panel first end that abuts the first side panel first end and a front panel second end that abuts the second side panel first end the front panel first end includes a first end first portion that is disposed parallel to the first side panel first portion, a first end second portion that is disposed parallel to the first side panel second portion, and a first end arcuate portion extends between the first end first portion and the first end second portion, the first end arcuate portion abuts the first side panel arcuate portion to define a first arcuate corner. ### Claim 11 (depends on 10) The heat exchanger assembly of claim 10, wherein the front panel second end includes a second end first portion that is disposed parallel to the second side panel first portion, a second end second portion that is disposed parallel to the second side panel second portion, and a second end arcuate portion extends between the second end first portion and the second end second portion, the second end arcuate portion abuts the second side panel arcuate portion to define a second arcuate corner. ### Claim 12 (depends on 11) The heat exchanger assembly of claim 11, further comprising: a rear panel extending between the first side panel second end and the second side panel second end and separating the first outlet from the second outlet.
