摘要

The invention relates to a manifold (1) with a circular cross-section having a deviation angle of 180 degrees for a tube bundle heat exchanger (100) for large product pressures, having a first and a second flange (2, 3) on each inlet (E) and outlet (A) of the manifold (1), in addition to a method for producing a tube bundle heat exchanger (100) comprising said type of manifold (1) and to the use of a tube bundle heat exchanger (100) for large product pressure having said type of manifold (1) in a spray drying system. The aim of the invention is to produce a manifold for a tube bundle heat exchanger for large product pressure, which has, amongst other things, the required strength and sustainable dimensional accuracy and is optimized in terms of flow technology during the course of the production thereof. A manifold (1) of said type can be achieved due to the following: the manifold (1) consists of two manifold halves (1.1, 1.2) which are respectively made of a single piece such that each manifold half (1.1, 1.2) comprises a joining point (V) on the end facing away from the flange (2, 3) and that the manifold halves (1.1, 1.2) are connected together in a material fit on the associated connection point (V) and that the extension of the passage cross-section of each manifold half (1.1, 1.2) is formed by rotationally symmetrical through-openings, from which at least one of the flanges (2, 3) and at least one of the associated connecting points (V) extends in the respective coaxial arrangement on the rotational axes (X1.1, Y1.1; X1.2, Y1.2), and that the first and the second rotational axes (X1.1, Y1.1) of the through openings of the first manifold halves (1,1) and the third and the fourth rotational axes (X1.2, Y1.2) of the through openings of the second manifold halves (1.2) extend on a common plane, which represents a meridian plane (M) for each flange (2, 3).
