Abstract
A heat exchanger includes a heat exchanger core including a cold side and a hot side. The cold side directs a first cooling fluid from a cold inlet to a cold outlet. The hot side directs a hot fluid from a hot inlet to a hot outlet. An inlet header coupled to the hot side of the heat exchanger core at the hot inlet includes an interior wall and an exterior wall spaced apart from the interior wall. The interior wall defines an inlet duct; the interior wall and exterior wall define a cooling channel surrounding at least a portion of the inlet duct. The inlet duct directs hot fluid though the inlet header to the hot side. The cooling channel directs a second cooling fluid through the cooling channel.
