Abstract
In a header of a heat exchanger core, a header passage includes: at least one radial passage extending along a radial direction, and a plurality of circumferential passages branched from each radial passage and communicating with one or more of the axial passages, respectively. The flow passage area of each radial passage is smaller in a second position than in a first position, where the second position is inward of the first position in the radial direction.
