Coupling variable 3D -> 1D

in a 3D-heat-transfer problem there is a heat flux to a tube with a Derichlet-boundary-condition. For calculating heat transfer in the tube I want to use a 1D-geometry with a line. For it I have to couple the heat flux of the boundary condition of the 3D-model to an inner source and sink in the 1D-model. Therefore the heat flux has to be integrated over the perimeter of the tube for the length of the tube to get a function Qt=f(x).
See the attached file for the situation. What kind of coupling variable I have to use? How the transformation has to be set up? I tested projection coupling, but it doesn't work because of the quad elements of the extruded mesh in 3D. Integration coupling integrates over the whole face and extrusion coupling isn't right ?!
Has anybody an idea how it works?
Best regards and thank you very much
