Definitions

  • the corrugated fin heat exchanger drainage structure of the present invention has a plurality of flat heat exchange tubes parallel to each other between a pair of opposing header pipes in a horizontal direction. Corrugated fins formed by alternately repeating valley folds are joined between the heat exchange tubes, and the ridges extending at the ends in the width direction of the heat exchange tubes are cut and raised in an inclined manner.
  • a corrugated fin type heat exchanger in which a flow channel is formed by a piece, a plurality of the cut and raised pieces formed on each heat exchange tube are appropriately spaced along the longitudinal direction of the heat exchange tube.
  • heat exchange performance can be improved by providing the fin louver 4a in the corrugated fin 4, that is, by providing a predetermined number of louvers formed at a predetermined angle in the air passage, heat transfer performance due to the turbulent flow effect or the like. Can be improved.
  • a four-step evaluation test was conducted: good ( ⁇ ), good drainage ( ⁇ ), drainage function but slow speed ( ⁇ ), poor drainage, or impossibility (x). As a result, the results shown in Table 1 were obtained.
  • the fin pitch (P) is preferably about 1.6 mm.
  • the condensed water (condensed water) condensed on the surface of the corrugated fins 4 and forming water droplets is sequentially discharged to the corrugated fins 4 on the lower side.
  • at least one cut and raised piece 8 is arranged for one mountain of the corrugated fin 4, and smooth drainage is possible. Thereby, even when the flat heat exchange tube 3 is horizontally arranged, the drainage speed can be increased, and the drainage performance can be improved.
