Definitions

  • This invention relates generally to tube fins for large scale field-erected air cooled industrial steam condensers or dry coolers/condensers.
  • the current finned tube used in most large scale field erected air cooled industrial steam condensers uses a flattened tube that is approximately 11 meters long by 200 mm wide (also referred to as "air travel length") with semi-circular leading and trailing edges, and 18.7mm external height (perpendicular to the air travel length).
  • Tube wall thickness is 1.35mm.
  • Fins are brazed to both flat sides of each tube and have a length that extends perpendicular to the longitudinal axis of the tube.
  • the fins are usually 18.5 mm tall, spaced at 11 fins per inch.
  • the fin surface has a wavy pattern to enhance heat transfer and help fin stiffness.
  • the standard spacing between tubes, center to center, is 57.2mm.
  • the tubes themselves make up approximately one third of the cross sectional face area (perpendicular to the air flow direction); whereas the fins make up nearly two thirds of the cross section face area. There is a small space between adjacent fin tips of 1.5mm.
  • maximum steam velocity through the tubes can typically be as high as 28 mps, and more typically 23 to 25 mps.
  • the invention is defined in claim 1.
  • the present invention is a new fin design to improve heat transfer between the fluid in the tube and the fluid (air) passing over/through the fins.
  • the fin may be generally planar and in direct contact with a flattened ACC tube.
  • the internal dimension of the tube in the direction parallel to the flat sides (also call the air travel length) may be typically 200 mm.
  • the external tube height (perpendicular to the air travel length) may be typically 18.7 mm, although fins of the present invention may be used with heat exchange tubes of any dimension.
  • the fluid to be cooled flows in the tube, which may be perpendicular to the fin plane. Cooling air may flow parallel to the plane of the flat side of the tube and perpendicular to the longitudinal axis of the tube.
  • a plurality of arrowhead shapes are pressed into or embossed onto each fin.
  • the arrowhead shape is defined by two intersecting wedge sections.
  • the shapes of the volume described by the embossed metal surface and the plane of the flat fin may be characterized as similar in form to a prism.
  • the wedge sections are triangular in cross section normal to their length.
  • the two intersecting wedge sections form a pointed end at the leading edge of the arrowhead shape and a forked end at the trailing edge of the arrowhead shape.
  • each wedge in a direction perpendicular to the plane of the fin is 50% or approximately 50% of the distance between adjacent fins.
  • the leading and trailing edges of each wedge are preferably oriented at 30° or approximately 30° from the air flow direction/longitudinal axis of the fin.
  • the top wedge section (relative to the location of the tube) forming an arrowhead shape has leading and trailing edges oriented 30° up, and the lower wedge section for each arrowhead shape has leading and trailing edges oriented 30° down.
  • the pressed arrowhead shapes according to the invention are grouped into pairs, where a first arrowhead shape of a pair is immediately upstream of the second arrowhead shape in the pair.
  • one of the arrowheads in a pair is pressed as a positive relative to the fin plane and the other of the pair is pressed as a negative relative to the fin plane.
  • the arrowhead pairs are placed in rows parallel to the air flow direction and spaced normal to the air flow direction one to two times the fin width dimension.
  • Arrowhead pairs in one row are preferably staggered relative to the arrowhead pairs in the adjacent row along the fin in the air flow direction. So the first arrowhead in the second row is spaced down the air flow direction along the fin by half of the space between arrowhead pairs along the rows.
  • the arrowhead pairs in a single row are spaced in the direction of air flow according to a multiple of the fin spacing, preferably 6 to 12 times the fin spacing and more preferably 8 or 9 times the fin spacing.
  • the dimensions of the arrowheads are a function of the fin height.
  • all arrowhead pressings on a given fin point in the same direction with respect to the flow direction. With each subsequent fin, the arrowhead pressings alternate between pointing in the flow direction and against the flow direction.
  • a plurality of arrowhead shapes 2 are pressed into or embossed onto each fin 4.
  • Each arrowhead shape 2 is defined by two intersecting wedge sections 6a, 6b.
  • the shapes of the volume described by the embossed metal surface and the plane of the flat fin may be characterized as similar in form to a prism.
  • the wedge sections 6a, 6b are triangular in cross section normal to their length.
  • the two intersecting wedge sections 6a, 6b form a pointed end 8 at the leading end of the arrowhead shape 2 and a forked end 10 at the trailing end of the arrowhead shape 2.
  • the pressed arrowhead shapes 2 may be grouped into pairs 16, where a first arrowhead shape 16a of a pair is immediately upstream of the second arrowhead shape 16b in the pair.
  • the pointed end of the second arrowhead shape 16b may be nested into the back end (or "forked end") of the first arrowhead shape 16a.
  • Fig. 1 shows one of the arrowheads in a pair pressed as a positive relative to the fin plane (out of the fin plane) and the other of the pair pressed as a negative relative to the fin plane (into the fin plane).
  • Figs. 1 , 4 , 10 and 11 show the arrowhead pairs placed in two rows parallel to the air flow direction.
  • the rows are spaced from one-another normal to the air flow direction one to two times the fin width dimension.
  • the arrowhead pairs in one row are shown staggered relative to the arrowhead pairs in the adjacent row along the fin in the air flow direction so that first arrowhead in the second row is spaced down the air flow direction along the fin by half of the space between arrowhead pairs along the rows.
  • the arrowhead pairs in a single row are shown spaced in the direction of air flow according to a multiple of the fin spacing, preferably 6 to 12 times the fin spacing and more preferably 8 or 9 times the fin spacing.
  • the dimensions of the arrowheads are preferably a function of the fin height.
  • All arrowhead pressings on a given fin point in the same direction with respect to the flow direction. With each subsequent fin, the arrowhead pressings alternate between pointing in the flow direction and against the flow direction.
