Abstract (en)
[origin: EP0449124A1] An annular space heat exchanger, which consists of at least three tubes (2-5) arranged concentrically one inside another, so that there are produced between the individual tubes annular spaces or annular chambers (7-9), through the respectively inner one of which the heat carrier, and through the respectively outer one of which the heat-absorbing medium flows, the heat carrier being gas, and the heat-absorbing medium a liquid medium, is to be constructed such that as high an efficiency as possible is achieved in conjunction with universal usability of the heat exchanger. Furthermore, it is to be possible to produce the heat exchanger with as low as possible an outlay on manufacturing. According to the invention, it is provided for this purpose that the heat-carrying medium is subjected in the inner annular chamber to a helical flow which conducts the medium around the inner tube. <IMAGE>
