| titleOfInvention | Method for producing a matrix hollow profile of a heat exchanger |
| abstract | The present invention deals with a method for the production of hollow, aerodynamically optimally shaped flow profiles according to their application requirements, the respective outer skin of which is flowed around by a first working medium (hot gas) during operation, while channels located inside the flow profiles are simultaneously supplied with a second working medium (compressed air). are flowed through. In order to create, among other things, the aerodynamic, strength-related and temperature requirements grown flow profiles in a comparatively simple manner, e.g. for the matrix of a heat exchanger or as turbine guide vanes or rotor blades for turbo machines, the method according to the invention provides the following essential features: With a substantially circular, square or polygonal cross-section, accumulations of material are formed on predetermined locations, preferably uniformly distributed on the circumference of the pipe, by means of suitable machining processes; - Then the pipe is deformed by pulling or rolling so that the one material accumulations an upstream and downstream wall reinforcement on or in the area of the upstream and downstream end edges of the flow profile, the other material accumulations by welding, soldering or the like. create separating webs that can be fixed to one another in the meridian plane for at least two separate compressed air ducts. |
