<p>A heat exchanger (1A) is provided with: a structure (3) which forms a first flow passage (2) for allowing a first fluid to flow therethrough; and pipes (5) which form second flow passages (4) for allowing a second fluid to flow therethrough and which are arranged in a predetermined direction within the first flow passage (2). Each of the pipes (5) includes a serpentine section (51) which serpentines in the predetermined direction so that adjacent pipes (5) approach and separate from each other. As a result of this configuration, the cross-sectional area of the first flow passage (2) is small in comparison to that of conventional heat exchangers because the arrangement direction of the pipes (5) and the serpentine direction coincide with each other. Consequently, the heat exchanger is compact in comparison to the conventional heat exchangers.</p> |
