Wing profile connecting arm (1120), carrier between hub segment (1130) and mixer vane module (1110) It provides connection. The wing profile connecting arm (1120) is centered thanks to its profile geometry that comes into contact with the fluid. It may also contribute to the direction of the fluid in the region toward the mixing vane module (1110). However, the protection of the invention Its scope is not limited to a specific manufacturing method or cross-sectional shape of the wing profile connecting arm (1120). The mixer vane module (1110) extends between the fluid inlet region (1111) and the fluid outlet region (1112). In the mixer vane module (1110), at least three module centers are joined in a common module center region. There are attached wing arms (1114). The wing arms (1114) are centered on the module in accordance with their numbers. They are arranged around it at preferably equal angular intervals. Six wing arms (1114) are shown in the drawings. However, the invention is not limited to this number. 3 35 40 45 In each mixing vane module (1110), there is only one on the side where the vane profile connecting arm (1120) is attached. The connection contour (1115) is located. The connection contour (1115) is the wing arm (1114) connected to the centers of the two modules. It connects, contributes to the connection of the wing-profiled connecting arm (1120) to the module and the partially enclosed outer It forms an enclosed bridge area within the structure. Apart from the connection contour (1115), the module outer contours are on the outside of the wing arms (1114) connected to the module center. (1116) is found. Two wings are joined by the connection contour (1115), where K is the number of wing arms (1114). The number of module outer contours (1116) corresponding to the wing arms other than the main arm is K-2. Module outer contours (1116) surrounds the wing arms (1114) only partially from the outside; the gaps between them are a closed circumferential channel. It does not close in a way that would create a blockage. Between the wing arms (1114) connected to the module center, the connection contour (1115) and the module outer contours (1116) Multiple flow passages (1113) are defined. Flow passages (1113) are located from the fluid inlet region (1111) to the fluid outlet. It extends uninterrupted to region (1112). Each flow passage (1113) extends outside the module along the said length. It includes a lateral opening around its perimeter. This allows a portion of the material to contribute to reducing local accumulation. While the material can be directed outwards, the remaining material consists of wing arms (1114), connection contour (1115) and module outer contours. (1116) is subjected to helical flow orientation. Therefore, flow passages (1113) are closed cross-section or It is not a polygonal cross-section pipe channel; it is a flow diverter that is partially enclosed but continuously open to the external environment.
