PROBLEM TO BE SOLVED: To provide a fin tube type heat exchanger with an improved heat exchanging efficiency and excellent appearance, favorable for fin press forming and eliminating frost remaining status without erroneous detection by a temperature sensor. SOLUTION: The fin tube type heat exchanger comprises a plurality of rows of heat transfer tubes 2 arranged in an air flow direction, an integral type fin group 3 superposed on the plurality of rows of heat transfer tube 2 with a specified interval, and a division type fin group 4 divided and superposed for each row 2a of the heat transfer tube, that are combined and provided in an extending direction of the heat transfer tube 2. A ratio of superposition of the integral type fin group 3 to superposition of the division type fin group 4 is designed to fall in between 4 to 6 and 6 to 4. COPYRIGHT: (C)2003,JPO |
