Abstract (en)

[origin: EP2735832A1] A heat exchanger 100 includes a plurality of heat exchange segments 10. Each of the heat exchange segments 10 is composed of an inner tube assembly 26 including two inner tubes 24, and an outer tube 28. A gap width G represented by a difference ((Æin / 2) - Æout) between a half of an inner diameter Æin of the outer tube 28 and an outer diameter Æout of the inner tube 24 satisfies 0 < G ‰¤ 0.8 (unit: mm). A path number N indicating the number of the heat exchange segments 10 and the inner diameter Æin (unit: mm) of the outer tube 28 satisfy one of relationships (1) to (5) below. (1) N = 4 and 8.20 ‰¤ Æin ‰¤ 9.50 (2) N = 5 and 7.58 ‰¤ Æin ‰¤ 8.90 (3) N = 6 and 7.14 ‰¤ Æin ‰¤ 8.50 (4) N = 7 and 6.78 ‰¤ Æin ‰¤ 8.20 (5) N = 8 and 6.52 ‰¤ Æin ‰¤ 7.90
