摘要:
The apparatus includes at least one heat exchanger (30) secured on the inline measuring device. Temperature-control fluid flows through the heat exchanger (30), at least at times during operation, for the purpose of transporting heat. The apparatus additionally includes securement means (50, 60) for the, especially releasable, fixing of the heat exchanger (30) externally on the inline measuring device (1). The heat exchanger (30) has an inner wall (32), especially a trough- or dish-shaped inner wall, contacting the inline measuring device (1) externally at least partially flushly, as well as an outer wall (31) fixed to the inner wall (32). The outer wall (31) is connected with the inner wall (32) via a connecting seam (90) running along an edge region and sealing against escape of the temperature-control fluid, and via a plurality of, especially point, or ring, shaped, inner connection locations (80), which are arranged spaced from one another in an inner region at least partially enclosed by the edge connection seam (90). Between the inner wall (32) and the outer wall (31) is at least one chamber (H) having a plurality of sections communicating with one another and serving to convey the temperature-control fluid. The chamber (H) is connected into a piping system conveying the temperature-control fluid via openings (33A, 34A) opening into the chamber.

摘要:
An electronics housing comprises a housing basic body having a cavity, especially a single cavity. The housing basic body includes a side wall laterally bordering the cavity, an open end and a rear wall bounding the cavity on an end lying opposite the open end and remote therefrom. Also included is a housing lid releasably connected to the housing basic body on the open end and sealing the housing basic body; and an intermediate floor. The intermediate floor, in the case of the electronics housing of the invention, forms: a gap extending between an inner surface of the side wall of the housing basic body and a lateral surface of the intermediate floor facing the inner surface; and two housing chambers in the cavity of the housing basic body separated from one another by the intermediate floor. A first housing chamber is arranged on a first side of the intermediate floor facing the housing lid and a second housing chamber is arranged on a second side of the intermediate floor facing away from the housing lid. The intermediate floor is inserted into, and releasably affixed to, the housing basic body.
