Abstract (en)
[origin: EP2042821A2] The exchanger has a base body (1) with heat emitting and absorbing flow channels (4, 5) respectively for a heat emitting medium and a heat absorbing medium e.g. hot water. A heat transfer from the emitting medium to the absorbing medium takes place over a heat transmitting wall (3). The channel (5) is helically guided along the wall and is limited by a helical fin (6). Another heat-absorbing flow channel (7) for another heat-absorbing medium e.g. drinking water, is arranged in the channel (5), follows a helical run of the channel (5), and is partially surrounded by the former medium.
