Definitions

  • the present invention relates to a heat exchanger-use fin and a guide that is used in the heat exchanger-use fin.
  • part of the fin is cut and raised to dispose erect portions or slits and louvers are disposed around holes into which heat transfer tubes are inserted. Further, annular collars that surround those holes are erected on the heat exchanger-use fin.
  • distal ends of the erect portions have been in lower positions than distal ends of the collar. This is because, when plural heat exchanger-use fins are stacked on top of each other, the fin that has been stacked on top is supported by the collars.
  • the present invention has been made in view of the aforementioned circumstances, and it is an object thereof to raise heat exchange efficiency.
  • a heat exchanger-use fin pertaining to a first aspect of the invention is a fin attached to heat transfer tubes and is equipped with a fin body, a plurality of collars and erect portions.
  • the fin body extends in a predetermined direction, and plural holes into which the heat transfer tubes are inserted are disposed in the fin body along the predetermined direction.
  • the collars are erected surrounding the holes, such that one collar surrounds each hole, on the same side with respect to the fin body. When the fin is seen from the collars side, the collars are all disposed between two straight lines that extend along the predetermined direction on a surface of the fin body, and outer peripheries of the collars contact the two straight lines.
  • the erect portions are erected on the fin body on the same side as the collars and are positioned outside the two straight lines. Distal ends of the erect portions are in higher positions than distal ends of the collars when seen from the surface.
  • a heat exchanger pertaining to a second aspect of the invention comprises: the heat exchanger-use fin according to the first aspect of the invention; and heat transfer tubes that are inserted into the holes disposed in the heat exchanger-use fin.
  • a guide pertaining to a third aspect of the invention is a guide that is used in the heat exchanger-use fin pertaining to the first aspect of the invention, wherein first and second grooves that extend in a certain direction are disposed.
  • the first and second grooves are disposed alternately in a direction perpendicular to that direction.
  • the second grooves are deeper than the first grooves.
  • a guide pertaining to a fourth aspect of the invention is the guide pertaining to the third aspect of the invention, wherein a depth of the first grooves is substantially equivalent to a height of the collars when seen from the surface of the fin body.
  • a guide pertaining to a fifth aspect of the invention is the guide pertaining to the third or fourth aspect of the invention, wherein a depth of the second grooves is larger than a height of the erect portions when seen from the surface of the fin body.
  • a guide use method pertaining to a sixth aspect of the invention is a method of using the guide pertaining to any one of the third to fifth aspects of the invention.
  • the guide use method comprises: slidably fitting the plurality of collars belonging to the same heat exchanger-use fin into one of the first grooves in the guide; and fitting, into the second groove that is adjacent to the first groove, the erect portions belonging to the same heat exchanger-use fin as the collars that fit into that first groove.
  • a guide use method pertaining to a seventh aspect of the invention is the method pertaining to the sixth aspect of the invention, further comprising evacuating air in a space that is enclosed by the collars that belong to the same heat exchanger-use fin and are mutually adjacent in a predetermined direction and by an inner wall of the first groove.
  • the distal ends of the erect portions are in higher positions than the distal ends of the collars, so in a heat exchanger obtained by attaching that heat exchanger-use fin to heat transfer tubes, air flowing into that heat exchanger can be efficiently agitated. Thus, heat exchange efficiency rises.
  • the heat exchanger-use fin can be moved to a predetermined position.
  • the erect portions are positioned outside those two straight lines, it is easy for the space between the collars that are mutually adjacent in the predetermined direction to be placed in a substantially hermetically sealed state by the two guides that sandwich the collars.
  • heat exchanger pertaining to the second aspect of the invention, air flowing into the heat exchanger can be efficiently agitated, so heat exchange efficiency is high.
  • the guide can be used in a heat exchanger-use fin that is equipped with the erect portions where the positions of its distal ends are higher than the positions of the distal ends of the collars.
  • the space between the collars that are mutually adjacent in the predetermined direction can be placed in a substantially hermetically sealed state by those collars and an inner wall of the first groove.
  • the heat exchanger-use fin can be drawn to the guide even without holding the heat exchanger-use fin from the opposite side of the guide.
  • the heat exchanger-use fin is easy to handle in the manufacturing process.
  • the erect portions can be prevented from contacting the guide when the erect portions are fitted in the second grooves.
  • the guide use method pertaining to the sixth aspect of the invention by fitting and sliding the plurality of collars belonging to the same heat exchanger-use fin in one of the first grooves, that heat exchanger-use fin can be moved to a predetermined position. Because the first grooves are plurally disposed in the guide, plural heat exchanger-use fins can be moved in parallel to predetermined positions. Moreover, because the erect portions fit in the second grooves, it is difficult for the movement of the heat exchanger-use fins to be hindered by the erect portions.
  • the air pressure in the space can be lowered by evacuating the air in that space.
  • the heat exchanger-use fin is drawn to the guides.
