Abstract (en)
A combination of tank members (2, 3) forms a fluid path for guiding a first heat exchange medium substantially in a first direction. A plurality of microtubes (1) each having an outer diameter D are interposed between the tank members (2, 3). A second heat exchange medium is guided by these microtubes (1) in a second direction intersecting the first direction for heat exchange with the first heat exchange medium. The microtubes (1) are staggered to have a pitch X in the first direction and are aligned to have a pitch Y in a third direction perpendicular to the first and the second directions. In particular, the pitch Y is selected within a range specified by 1.8 </= Y/D </= 2.4. It is preferable that the pitch X is selected within a range specified by 1.12 </= X/D </= 1.8. <IMAGE>
