Abstract: The invention concerns a temperature compensating element (40) for a pipe (30), wherein the temperature compensating element (40) has at least one phase-change element (20) and can be inserted into the pipe (30) in such a way that the temperature compensating element (40) lies flat against an inside surface (32a) of a pipe casing (32) of the pipe (30) and that the phase-change element (40) is in thermal contact with the pipe (30), and wherein the temperature compensating element (40) forms a through-channel (22) along a running direction (100) of the pipe (30).

Abstract: The invention relates to a plate heat exchanger (1) for a process engineering system (2), having a plurality of lamellae (3, 4) and a plurality of separating plates (5-7), which are arranged alternately, wherein at least one separating plate (6) has an optical waveguide (35) that is embedded in the at least one separating plate (6) in such a way that the optical waveguide (35) is covered on both sides by material of the at least one separating plate (6) in a first direction (R1) and in a second direction (R2), which are each oriented perpendicular to a plane (E) defined by the at least one separating plate (6) and in opposite senses with respect to one another.

Abstract: The invention relates to a fluid-conducting device (10) having a conduit block (12), within which there are formed multiple primary conduits (14) which extend in a primary conduit direction (100) and which are designed to conduct a primary fluid. The fluid-conducting device furthermore has at least one secondary conduit (16), which extends at least partially in a secondary conduit direction (102) extending at least partially perpendicular to the primary conduit direction (100) and which is designed to conduct or to receive a secondary fluid.

Abstract: The present invention concerns a method for producing a plate heat exchanger (1) with a multiplicity of parting sheets (20) and a multiplicity of fins (11, 12), a fin being respectively arranged between two neighboring parting sheets, wherein at least one capillary (30) with at least one thermocouple and/or measuring resistor element (40) is introduced into at least one parting sheet (20), and wherein in each case a parting plate of the multiplicity of parting plates and a fin of the multiplicity of fins are alternately arranged and are connected to one another in a material-bonding manner, and concerns a plate heat exchanger (1) produced in such a way.

Abstract: The invention relates to a fluid conduit component, designed to be flowed through by a fluid in a direction of flow. The fluid conduit component has a conduit wall, which extends along the direction of flow and at least partially forms a conduit channel. Furthermore, the fluid conduit component has at least one capillary, which at least partially runs along the direction of flow and within the conduit wall and is enclosed by said conduit wall and/or is arranged within a capillary module arranged on an inner side of the conduit wall facing the conduit channel and is enclosed by said capillary module. The conduit wall is in this case formed with the capillary running at least partially therein and/or with the capillary module at least partially by an additive manufacturing process. Furthermore, the invention relates to a method for producing a fluid conduit component.
