Definitions
- the invention relates to a tube with twisted inner ribs, the to the symmetry longitudinal axis of the tube rotationally symmetrical run.
- a known tube of this type according to DE-GM 74 22 107 has on its inside several multi-course helical Inner ribs on which a small width b and a small radial Have extension e.
- EP 0 582 835 A1 discloses a heat exchanger become known, consisting of several, in their outer wall graded, non-generic pipes composed in whose Interior further differently configured tubes with different dimensions and internal ribs concentric are arranged, which are to serve as oil cooler.
- These Heat transfer tubes are in addition to their complex production Afflicted with the disadvantage of a significant pressure loss, because also - as far as it is present - a the Heat transfer increasing crossflow either not or can only happen accidentally and on the inner tube remains limited.
- Heat transfer tube of the type mentioned above create, which is compared to the previously known internally ribbed pipes by a significantly better Heat transfer performance excels and for this purpose not only an increase in the internal heat transfer surface operated, but also an effective cross flow between the Inner wall surface of the tube and the core flow near the SymmetrielShsachse for heat transfer increase guaranteed.
- each rib forms the Cross-sectional shape of each rib a pointed, isosceles Triangle with straight leg sides, whose Triangle point by means of a radius rounded off in the two Leg sides merges, each with two adjacent inner ribs form a trapezoidal cross-section space.
- cross-sectional shape is basically from DE 33 34 964 A1 known, but there run the ribs without any twist, so that in conjunction with the twisting features of claim 1 not to be known as known.
- each inner fin of the tube the shape of a Tooth on gears with convex outward flanks with rounded tooth tip, with two adjacent ribs a cross-sectionally U-shaped intermediate space with concave encompass sunken side surfaces.
- This rib shape is especially suitable for high viscosity fluids such as oils.
- each inner rib an isosceles, pointed triangle with concave inward-falling thorns and a semicircular shape at the top, with two adjacent each Internal ribs a trapezoidal space in cross section Embrace U-shaped, whose trapezoidal leg convexly outwards are arched.
- This rib shape is preferably used in the Flow through fluids of low viscosity, as they for example, have gases.
- these tubes are mass-produced with their Internal ribs made of extruded aluminum or copper or out made of extruded plastic. It is characterized both Aluminum as well as copper due to a high thermal conductivity.
- the wall thickness of the pipe is determined by the System pressure determined and is advantageous in a range between 0.4 mm and 3 mm, each tube having at least four internal ribs having.
- the distance a is the free ends of the inner ribs of the symmetry axis of the Pipe in fluids of high viscosity, such as oils, larger and at Low viscosity fluids, such as water and gases, lower sized. This increases the cross section of the Core flow in the area of the free cross section near the Symmetry longitudinal axis against high viscosity fluids Low viscosity fluids.
- Fig. 1 is a first embodiment of the inventive tube 1 shown. This forms the Cross-sectional shape of each rib 2 a pointed, isosceles Triangle with straight leg sides 2a, 2b, whose Triangle tip 2c rounded by a radius r in the two Leg sides 2a, 2b passes. Two adjacent each Inner ribs 2 form a trapezoidal in cross-section Gap 2d.
- each inner rib 3 of the tube 1, the shape of a tooth in gears with convex outside curved side flanks 3a, 3b with a rounded Tooth tip 3c on.
- Two adjacent ribs 3 surround one in cross-section U-shaped space 3d with convex sunken side surfaces that are identical to the shape of the Side edges 3a, 3b of the ribs 3 are.
- each inner rib 4 forms a isosceles, pointed triangle with concave inward incident leg sides 4a, 4b with a semicircular Tip 4c.
- each case surround two adjacent inner ribs 4 U-shaped a cross-section trapezoidal space 4d, whose trapezoidal legs are curved convexly outward and identical to the leg sides 4a, 4b.
- Each tube 1 is provided with at least four inner ribs 2, 3, 4, in present case, each with eight inner ribs 2, 3, 4 provided.
- the Free ends 2c, 3c, 4c are with the tips of the cross-sectional shapes the individual inner ribs 2, 3, 4 identical. It must, however be noted that the tips are on the flat Cross-sectional body of a triangle, whereas the free ends are on a twisted to the symmetry longitudinal axis 5 extending refer to spatial body.
- These free ends 2c, 3c, 4c have to the symmetry longitudinal axis 5 of the tube 1 a distance a, in the Ratio to the pipe inside diameter d in a range of 1: 12 to 1: 3 is.
- the tubes are advantageous either from an extruded Aluminum or copper produced or extruded in plastic.
- the wall thickness d 1 of the tube 1 is dependent on the system pressure and is in a range between 0.4 mm and 3 mm.
- tubes 1 also other than those in Figures 1 to 3 shown tubes may consist, that is for example, only four, instead of the eight ribs 2, 3, 4 shown there Ribs 2, 3, 4 or more than eight ribs in the interior of the tube. 1 are arranged. Because the number of ribs 2, 3, 4, the length L of Twisting as well as the thickness and rib shape are dependent on the type of fluid and its flow velocity as well designed by the pressure drop. The general flow rule applies, that the smaller the free pressure, the greater the pressure drop Flow cross section in the core area and between the Single ribs 2, 3, 4, but that on the other hand with larger Number of ribs and larger size associated with it Heat transfer surface and the heat transfer performance passive rises.
- Such a tube 1 is used, for example a shell and tube heat exchanger 12, as shown in Fig. 6.
- a tube 1 enters the cooling medium through the pipe 13 in the tubes 1 and exits through the outlet 14.
- Im Countercurrent occurs, for example, to be cooled medium through the Inlet 15 to the outside 11 of the tubes 1 and leaves the heat exchanger 12 in the cooled state by the Outlet 16.
- the inventive Tube 1 both for cooling and for heating fluids Can be used, depending on the direction of the Heat transfer process to take place.
