To provide a heat exchange core which can securely have relatively high heat exchange efficiency while the size thereof is reduced.SOLUTION: In a header part of a heat exchange core, a header flow channel includes at least one radial flow channel extending along a radial direction, and a plurality of circumferential flow channels communicating with one or more respective axial flow channels diverging from any one of the radial flow channels. The plurality of circumferential flow channels includes a first circumferential flow channel, and a second circumferential flow channels placed inside the first circumferential flow channel in the radial direction, and arranged in a circumferential direction over a total angle range larger than that of the first circumferential flow channel.SELECTED DRAWING: Figure 1 【課題】比較的高い熱交換効率を確保しつつ小型化できる熱交換コアを提供する。【解決手段】熱交換コアのヘッダ部において、ヘッダ流路は、径方向に沿って延在する少なくとも一本の径方向流路と、何れかの径方向流路から分岐して１以上の軸方向流路にそれぞれ連通する複数本の周方向流路とを含む。複数本の周方向流路は、第１周方向流路と、第１周方向流路よりも径方向内側に位置し、第１周方向流路よりも大きい総角度範囲に亘って周方向に配置された第２周方向流路とを含む。【選択図】図１
