Abstract

A heat exchanger having a housing, which defines a first volume (V1), and having at least one conduit, which defines a second volume (V2), wherein the housing has an inlet and an outlet and at least one first opening and at least one second opening located opposite the first opening relative to the housing, wherein the at least one conduit extends through the first volume (V1) and connects the at least one first opening of the housing and the at least one second opening of the housing, and is connected at the two ends of the conduit to the housing in a fluid-tight manner. In order to provide a heat exchanger which has an improved possibility for compensating for the differential thermal expansion of the housing and the conduits, the at least one conduit does not extend in a linear manner inside the first volume (V1), and the at least one conduit is monolithically connected in the region of the first opening of the conduit and/or the second opening of the conduit to the housing.

Dependent claims

A reactor with a heat exchanger, comprising:

a housing, which defines a first volume (V1), and comprising at least one conduit, which defines a second volume (V2),
wherein the housing has an inlet and an outlet and at least one first opening and at least one second opening located opposite the at least one first opening relative to the housing,
wherein the at least one conduit extends through the first volume (V1) and connects the at least one first opening of the housing and the at least one second opening of the housing, and is connected at two ends of the conduit to the housing in a fluid-tight manner,
wherein the at least one conduit does not extend in a linear manner inside the first volume (V1), and the at least one conduit is monolithically connected in the region of the at least one first opening and/or the at least one second opening to the housing,
wherein the housing has a middle part in the shape of a cylindrical shell, and two oppositely situated end pieces,
wherein the inlet and the at least one first opening are situated at the one end piece, and the outlet and the at least one second opening are situated at the other end piece, and
wherein a catalyst material is arranged in the at least one conduit or outside of the at least one conduit in the housing.
