    摘要: The invention relates to a device for inflowing in the stream area of a tube carrier plate (7, 8) of a heat exchanger provided with a tube bundle (1). The aim of the inventive device is to prevent the deposit of products containing solid materials in the critical areas of the tube carrier plate. For this purpose, a displacer (12. 12.1, 12.2, 12.3, 12.4) is concentrically arranged with respect to the relevant tube carrier plate (7, 8) in the stream area of a tube carrier plate (7, 8) which is defined on the external side thereof by a first or second passage cross section (5c, 8c) extended inside the exchanger flange (5) of a connecting piece (8d). Said displacer divides the flow in a symmetrically axial manner with respect to an internal pipe (3*), diverts outward and accelerates the flow in such a way that it converges in the form of a fluid tip in an annular space section (As) between the displacer (12. 12.1, 12.2, 12.3, 12.4) and the internal contour of the exchanger flange (5) or the connecting piece (8d) and, afterwards forms together with the passage cross section (5c, 8c) an annular space cross section (Ase) and expands.
