Definitions
- the invention relates to a finned tube heat exchanger according to the features in the preamble of claim 1.
- the finned tube heat exchanger according to DE-PS 34 19 734 is able to condense large amounts of steam. He also has the advantage that everyone Place the heat exchanger tubes between the pressure all areas of the pipe cross-section. Thereby is the condensation of the vapor in the direction of flow the front pipe sections facing the cooling air ended in exactly the same place as in the in the flow direction of the cooling air rear pipe sections. Dead zones can hardly occur. Furthermore relatively large pipe cross sections are formed, so that the flow pressure losses due to the larger hydraulic cross section can be significantly reduced.
- the perpendicular from the surfaces of the heat exchanger tubes protruding ribs are smooth and non-protruding educated.
- the Finned tube heat exchanger of DE-OS 19 58 909 in the Integrated ribs between the heat exchanger tubes Leading edges on. The leading edges are pressed out of surface sections from the plane of the ribs educated. As a result, the cooling air finds obstacles in front. The heat transfer is admittedly due to this measure improved, but bought the disadvantage that by the leading edges of the pressure loss increased several times.
- EP 0 490 210 A1 which is considered the closest prior art, also discloses a heat exchanger exchanger tubes running parallel to each other slim cross-section, the cross-sectional length being a Dimension several times larger than the cross-sectional width is. Extend on the flat outer sides of the exchanger tubes transversely to the longitudinal direction of the exchanger tubes either parallel U-shaped ribs or ribs combined into a meander band. The side faces the ribs are flat.
- the US 3,515,207 shows a heat exchanger with parallel round exchanger tubes running towards each other. Transversely to each other in parallel in several rows extending exchanger tubes extend fins, the circumference of flat square sections of the pipes and from the edge of the flat sections 90 ° offset to each other with zigzag cross-sections exist.
- the invention is based on the prior art Task based on such a finned tube heat exchanger to perfect that the outer Heat transfer between the cooling air and the surfaces of the heat exchanger tubes without any significant increase the pressure loss can be increased significantly.
- the ribs are on at least one side surface with a zigzag configuration Provide air guide grooves.
- the air guide grooves generally have one Extension transverse to the longitudinal direction of the heat exchanger tubes. she are open at the rib ends and thus allow the Cooling air to flow in the air guide grooves, being through the zigzag configuration a significantly improved external heat transfer between the cooling air and the surface of the heat exchanger tubes is reached, without noticeably increasing the pressure losses.
- the air guide grooves can cover the entire side surface extend a rib. They are preferably through corresponding embossing provided on both sides of a rib. In this case, the air guide grooves are adjacent Ribs face to face.
- the ribs configured according to the invention can be individually be provided on each heat exchanger tube. Especially however, it is advantageous if two are running side by side Heat exchanger tubes through fins with a zigzag shape running air guide grooves connected in a web-like manner are. These can be single ribs or wavy or U-shaped or trapezoidal ribbed ribbons act.
- each transition section is advantageous curved in a circular arc.
- the radii of the Transitional sections are appropriately identical.
- a particularly advantageous embodiment of the rib design is seen in the features of claim 4.
- each other parallel groove sections of the air guide grooves run not only zigzag in this embodiment the longitudinal plane of each rib, but also at an angle to that general length of a rib.
- the transition sections In order to deflect the cooling air in as swirl-free as possible to ensure the air guide grooves point accordingly Claim 6 the transition sections a radius of 1.5 mm to 3 mm.
- an air guide groove intersecting transverse planes and the distance of the intersection of the center lines of two successive groove sections of the line of symmetry is the distance between each a transverse plane intersecting a center of curvature and the intersections of the adjacent center lines of the Groove sections with the line of symmetry about 3 mm to 10 mm, preferably about 7.5 mm.
- the air guide groove s a semicircular Cross section with a radius and a depth of approximately 1 mm to 2 mm, preferably about 1.5 mm.
- the heat transfer conditions can further improve according to claim 11 in that the distance between two adjacent ribs is about 2 mm to 4 mm, preferably about 3 mm.
- FIGS Finned tube heat exchanger for condensing the exhaust vapors large turbine systems designated by cooling air.
- the finned tube heat exchanger 1 has several in parallel heat exchanger tubes arranged next to each other at distance A. 2 with an elongated cross section.
- the heat exchanger tubes 2 are connected by ribs 3, which are parallel to the flow direction SR Extend cooling air and through suitable fixing strips perpendicular to the side surfaces 4 of the heat exchanger tubes 2 are attached.
- Figure 1 shows that the length L of the cross section of the Heat exchanger tubes 2 several times larger than that Width B is dimensioned.
- the ribs arranged at a distance Al of 3 mm from one another 3 have 5 on both side surfaces in a zigzag configuration parallel to each other running and in the flow direction SR of the cooling air continuous, 6 air guide grooves open at the rib ends 7, with a corresponding embossing of the ribs 3 a thickness D of about 0.1 mm for aluminum or copper or approximately 0.5 mm in the case of steel (FIGS. 1 until 5).
- Each air guide groove 7 is made up of straight lines Groove sections 8 and two successive ones Groove sections 8 continuously connecting arcuate transition sections 9 together ( Figures 1, 3 and 4).
- Figure 4 shows an enlarged view Representation based on the highlighted Center lines 10 of two successive groove sections 8 the geometric relationships of an air guide groove 7.
- the arcuate transition sections 9 are semicircularly curved.
- the centers of curvature 11 of the transition sections 9 lie here at a distance from the symmetry line SL of the air guide groove 7.
- the transition sections 9 have a radius R1 from 1.5 mm to 3 mm.

- the intersection 12 of the Center lines 10 of two successive groove sections 8 is at a distance A3 of 3.5 mm from the line of symmetry SL arranged.
- the air guide grooves 7 a semicircular cross section with a radius R and a depth T of 1.5 mm.
- the distance A4 of the center lines 10 of two neighboring ones Air guide grooves is 5.0 mm ( Figures 1 and 5).
- the U-shaped ribbed belt 13 of FIGS. 6 to 8 consists of a plurality of ribs 3a and 3 Ribs 3a connecting fastening strips 14, 14a, which at the same time also the fixing of the ribbed belt 13 serve the heat exchanger tubes 2. Which is in the Level El-El extending mounting strips 14 extend parallel to the fastening strips arranged in level E2-E2 14a.
- the ribs 3a are in a longitudinal zigzag shape successive fields 15 each with parallel Groove sections 8a broken down.
- the groove sections 8a also form here, as in the embodiment of Figures 1 to 5, components of the length of the Ribs 3a through air guide grooves 7a.
