HEAT EXCHANGE DEVICE, AND USE THEREOF

摘要

The invention relates to a heat exchange device to be introduced along a longitudinal direction L to a drain pipeline, which extends along a longitudinal direction L and includes heat exchanger walls, comprising: - a first wall segment configured to make contact with wastewater; - a second wall segment spaced apart from the first wall segment configured to make contact with the drain pipeline, wherein the first wall segment and the second wall segment are arranged spaced apart from one another, at least sectionally, such that between the first wall segment and the second wall segment, a heat exchange chamber is formed; and - a third wall segment interconnecting the first and the second wall segment, which at least sectionally forms a first supply line, through which a heat exchange medium can flow, wherein the heat exchange chamber is hydraulically connected to the first supply line by way of a first connecting area; - a fourth wall segment interconnecting the first wall segment and the second wall segment, the fourth wall segment forming, at least sectionally, a second supply line, through which a heat exchange medium can flow, wherein the heat exchange chamber is hydraulically connected to the second supply line by way of a second connecting area. The invention further relates to the use thereof.
