Definitions
- the invention relates to a device for cooling a flow channel surrounding flow channel wall with at least one, in a through the Flow medium passing through flow channel inducing flow eddies Rib element on the side of the flow channel wall facing the flow channel is appropriate and its shape and size under one certain heat transfer coefficients and a certain one by which Overflow of the rib element with the flow medium in this connected Pressure loss are selected.
- the turbine blades, as well as the combustion chamber walls combined with cooling channels through which in the Relative to the temperatures of the hot gases, relatively cold air is fed in is branched off, for example, from the air compressor stage for cooling purposes.
- the cooling air flow flowing through the cooling channels cools the cooling channel walls and is warmed up by them.
- precautions have been taken by which the thermal coupling between Coolant and cooling channel wall can be optimized. So it is known that targeted by providing ribs on the inner wall of the cooling channel turbulent flow components within that passing through the cooling channel Coolant flow can be generated, the flow components perpendicular have on the cooling channel wall.
- the proportion of the coolant mass flow which comes into direct thermal contact with the cooling channel walls, be significantly increased, which also significantly improves the cooling effect becomes.
- straight ribs that are arranged obliquely to the main flow direction as is found has relatively stable and pronounced secondary flow vortices, which lead to increased mixing of the boundary layer near the cooling channel wall, through the increasingly cold cooling air can reach the hot cooling channel walls.
- the invention has for its object a device for cooling a Flow channel wall surrounding the flow channel with at least one, in one fluid flowing through the flow channel inducing rib element, that on the, facing the flow channel Side of the flow channel wall is attached and its shape and size below Given a certain heat transfer coefficient and a certain by the flow medium flowing over the rib element in it associated pressure loss are chosen to develop such that the cooling effect of the flow medium passing through the flow channel is further increased should be done without, by optimizing shape and size of the fin element existing heat transfer coefficient between the cooling channel wall and flow medium and without increasing the connected by the overflow of the rib element with the flow medium Suffering from pressure loss. Measures to increase the cooling effect are said to also with regard to their manufacture with little effort and low manufacturing costs be connected.
- a device according to the preamble of claim 1 is such trained that the rib element while largely maintaining its original shape and / or size its facing the flow channel Has surface enlarging contours.
- the idea according to the invention is based on the optimization of the outer rib contour with the aim of increasing the heat transfer surface between the rib and flow medium, however the heat transfer coefficient defined by the spatial shape the rib and the pressure loss caused by the rib shape should remain essentially unaffected in the flow medium.
- FIG. 1 A side of a cooling duct wall 1 is shown in cross section in FIG. on the flow channel inner wall two rib elements 2, 3 are provided are, which each have a rectangular cross section.
- a cooling channel delimited by four side walls, two of which are opposite Side walls are provided with rib elements, each in the direction of flow are arranged one after the other in multiple succession.
- Figure 1a is only in Longitudinal section of a half of a cooling channel 4 shown, the rib elements provided cooling channel walls are spaced from each other by the width H (shown is only the cooling channel up to H / 2).
- H shown is only the cooling channel up to H / 2
- the fin height e is approximately 10% of the cooling channel height H, which at the same time also corresponds to the hydraulic diameter of the cooling channel.
- the ratio of the distance p between two rib elements 2, 3 arranged directly adjacent in the longitudinal direction of the cooling channel and the rib height e is approximately 10.
- FIG. 2 shows a further embodiment of a rib element, which has a rectangular cross section and three grooves 6 for the purpose of enlarging the surface having. In addition, the edges are rounded.
- FIGS. 3a-d other cross-sectional shapes can also be used can be used for the rib elements, with surface enlarging Measures are not based solely on indentations in the rib elements are limited.
- FIG. 3a shows a conventional rectangular rib, which extends over its entire length has a constant cross-section.
- the rectangular rib shown in Figure 3b has a along its extent increasing rectangular cross-section.
- its cross-sectional shape is semicircular and a continuous in the longitudinal direction of the ribs has increasing semicircle diameter.
- for a surface enlargement changes all geometry parameters of the rib element like rib height, rib width, distance between two adjacent ribs in relation to their height as well as the inclination of the rib axis.
- FIGS. 4a-d there are combinations of grooves or grooves and specific changes in cross-section shown along the longitudinal axis of the ribs.
- Figure 4a shows one Rectangular rib with a constant rib cross-section and one worked into it Groove.
- Figure 4b shows a rib element with a rectangular groove and with in the longitudinal direction of the ribs increasing rectangular cross-section and one semicircular incorporated recess.
- FIG. 4c shows a triangular cross-sectional shape Ribs on both side flanks of straight recesses are provided.
- FIG. 4d has an original semicircular design Cross section on, in which a parabolic recess is incorporated.
- Three-dimensional depressions can also be worked into the rib elements are, as is apparent from Figures 5a - 5c.
- Figure 5a is a rectangular rib with a rectangular shape Wells shown.
- Figure 5b shows a semicircular in cross section trained rib with cylindrical recesses.
- Figure 5c instructs on its surface three-dimensional cubic body, through which a special large surface area enlargement is possible.

a = c = w/4
b = w/2
d = e/2 können folgende Feststellungen gemacht werden:
Der Oberflächenanteil, der durch-die Rippenelementoberflächen gebildet wird, im Verhältnis zur gesamten Wärmeübertragungsoberfläche innerhalb eines Kühlkanals beträgt, im Falle der Ausbildung eines Rippenelementes gemäß Figur 1a, 25%. Sind die Rippenelemente mit einer Nut gemäß dem Ausführungsbeispiel der Figur 1b versehen, so liegt ihr Oberflächenanteil gemessen an der gesamten Wärmeübertragungsoberfläche innerhalb eines Kühlkanals in der Größenordnung von 33%. Dies führt verglichen zum Ausführungsbeispiel gemäß Figur 1a zu einem Anstieg der gesamten Wärmeübergangsoberfläche innerhalb eines Kühlkanals um 8,3%. Unter der Annahme, dass die Oberfläche innerhalb der Nut in gleicher Weise zum Wärmeaustausch beiträgt, wie die übrige Oberfläche des Rippenelementes, beträgt die zu erwartende Zunahme des Wärmeübergangs durch die erfindungsgemäße Maßnahme 8,3%, also ebensoviel, um die die Wärmeübergangsoberfläche im Gesamtsystem zugenommen hat.
