Claim:
1. An apparatus for influencing an outflow region of a tube carrier plate of a tube bundle heat exchanger, in particular for the food and beverage industry, comprising: a tube bundle of the tube bundle heat exchanger, the tube bundle comprising inner tubes connected in parallel and respectively flowed through by a product on the inside, the inner tubes arranged in a circular-ring-shaped manner on a single circle and in an outer channel designed as an annular space extending in the longitudinal direction thereof and the inner tubes supported respectively on an end side in a first and a second tube carrier plate; an outer casing delimiting the outer channel from an outside and an inner casing delimiting the outer channel from an inside for a heating medium, with a number of the inner tubes together forming an inner channel; a product inlet designed for the inner tubes together and located on one side of the inner tubes in a first exchanger flange; a common product outlet for the product designed on the other side of the inner tubes in a second exchanger flange; a first connection opening arranged centrically in the first exchanger flange on its flange side facing away from the first tube carrier plate; a second connection opening arranged centrically in the second exchanger flange on its flange side facing away from the second tube carrier plate, the second connection opening extending axially symmetrically and radially opposite a direction of flow in the second exchanger flange, continuing up to an extended outlet-side passage cross-section on an end side of the second exchanger flange, and establishing a fluid-accessible connection to the inner tubes; and an axially symmetrical outlet-side displacement body fixedly connected coaxially to the second connection opening and concentrically to the second tube carrier plate, the axially symmetrical outlet-side displacement body forming an annular space-like outlet channel together with an outlet-side inner contour formed by the second connection opening and its radial extension up to the extended outlet-side passage cross-section; and the annular space-like outlet channel having a channel passage cross-section in an entirety of a region of the annular space-like outlet channel between a maximum outside diameter of the outlet-side displacement body and the second connection opening, the channel passage cross-section having a constant passage cross-section over an entire length of the region and corresponding in the region with a total passage cross-section of the inner tubes of the number that are flowed through in parallel, each of the inner tubes having an individual passage cross-section.
