EXCHANGER DEVICE

The invention relates to an exchanger device comprising a first and a second end piece and an exchanger body arranged in-between. At least one first and one second channel in the exchanger body connect inlets and outlets of the two end pieces, wherein the inlets and outlets are arranged in end faces of the end pieces, which face away from the exchanger body. The exchanger body forms a multi-helix, in particular a double helix or multiple concentric ring surfaces, wherein the windings of the multi-helix or the concentric ring surfaces form separating walls between the at least one first and the at least one second channel. The device according to the invention allows for the formation of exchanger devices with high efficiency yet also with a small outer diameter. The manufacturing process is also simplified.
