Abstract: A heat exchanger module for obtaining thermal energy from wastewater including a heat exchanger element inserted into a wastewater pipe allowing working fluid to flow, and a fluid line supplying or discharging the working fluid to or from the heat exchanger element. The heat exchanger element and the fluid line are fluidically connectable via a connection including a socket connected to the heat exchanger element, a through pipe connected to the fluid line and extending through a wall of the fluid line, and a screw element. The socket and screw element are threadedly engageable with each other through the through pipe so that a socket pressing surface is pressed onto a first through pipe pressing surface and a screw element pressing surface is pressed onto a second through pipe pressing surface to connect the heat exchanger element and the fluid line to each other in a fluid-tight manner.

Abstract: A heat exchanger module (1) has a supply pipe portion (4) and a return pipe portion (6) that are connected fluidically to a heat exchanger chamber (2) of the heat exchanger module (1). The supply pipe portions (4) of a plurality of heat exchanger modules (1) can be interconnected fluidically to form a supply pipe (24), and the return pipe portions (6) of a plurality of heat exchanger modules (1) can be interconnected fluidically to form a return pipe portion (26). A feed pipe (12) is arranged inside the supply pipe portion (4), and a heat exchange fluid can be fed via the feed pipe (12) to the supply pipe portion (4).

Abstract: Heat exchanger element for installation in sewage pipelines, the top side of which heat exchanger element has a heat-conducting exchange surface with heat exchanger chambers arranged on it, the heat exchanger element has in cross section a run-in gutter and run-off surfaces contiguous to the latter on both sides, and, in the region of the run-in gutter and the run-off surfaces, lines for the forward run, return run and distribution of a heat exchanger medium are arranged, the floor point of the run-in gutter, the lower region of the lines and/or the free margins of the run-off surfaces being designed as bearings for arranging the heat exchanger element in the sewage pipeline.

Abstract: The invention relates to a heat exchanger device to be introduced, along a longitudinal direction L, into a sewage pipeline extending along the longitudinal direction L, with a heat exchanger wall, comprising:—a first wall portion designed to make contact with sewage,—a second wall portion, spaced from the first wall portion, which is designed to make contact with the sewage pipeline, wherein the first wall portion and the second wall portion are arranged in a manner spaced from each other at least in some part(s) such that a heat exchanger chamber is formed between the first wall portion and the second wall portion, and—a third wall portion connecting the first wall portion and the second wall portion, the third wall portion at least in some part(s) forming a first supply line that can be flown through by a heat exchange medium, wherein the heat exchanger chamber is hydraulically connected to the first supply line via a first connection region,—a fourth wall portion connecting the first wall portion and the

Abstract: A heat exchanger assembly to be introduced into a sewage pipeline includes: at least one first heat exchanger adapted to thermally contact a heat source with sewage and at least one second heat exchanger adapted to thermally contact the sewage with a heat sink. The at least one second heat exchanger is arranged along the sewage flowing direction in the sewage pipeline and spaced from the at least one first heat exchanger, as well as to a method for transporting thermal energy.
