<p><P>PROBLEM TO BE SOLVED: To provide a finned heat exchanger capable of preventing drop of condensation water attached to the heat exchanger, having high heat exchanging capacity and suppressing generation of peculiar noise due to rotation of a blower. <P>SOLUTION: A roughly V-shaped front-side heat exchanger 20 and a back-side heat exchanger 40 are disposed, a distance Dx between a windward front edge 22 and a leeward rear edge 24 of a region X at a side near an once-through blower 5, of the front-side heat exchanger 20 is larger than a distance Dy of a region Y at a side far from the once-through blower 5 and a distance Dh of the back-side heat exchanger 40, the distance between the windward front edge and the leeward rear edge of the fin 21 is reduced toward a lower part from parts close to the once-through blower 5, of these regions, so that the condensate water attached to the fin is easy to smoothly flow down, and heat transfer tubes of two or more outer diameters are disposed in two rows or one row on the fin 21 at a lower part of the front-side heat exchanger 20 and in two rows or three rows on the fins at the upper part of the front-side heat exchanger 20 and the back-side heat exchanger 40 with the prescribed outer diameters and intervals. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
