WÄRMETAUSCHERSCHLANGE, TURBOPUMPENAUSLASS, DER EINE SOLCHE SCHLANGE UMFASST, UND HERSTELLUNGSVERFAHREN EINER SOLCHEN SCHLANGE

摘要

The invention relates to a coil (16, 18) for a heat exchanger, comprising at least a first turn and a second turn, the first and second turns being adjacent, each turn having, in a cutting plane transverse to the direction of flow d '' a fluid in the coil (16, 18), a wall delimiting a section for passage of the fluid in the coil, the passage section having a shape comprising a major axis and a minor axis, an orthogonal projection of one end of the major axis of the first turn on a straight line comprising the major axis of the second turn belonging to the major axis of the second turn, the first and the second turn having a portion of wall in common. The invention also relates to a turbopump exhaust (10 ) comprising such a coil and a method of manufacturing such a coil.
