Abstract

Bei einem wendelförmigen Wärmeaustauscher (1 ) mit einem Eintritt (2) und einem Austritt (3), überschneiden sich bei der Ansicht in Richtung Mittelachse (6) der Wendel der Bereich (4), in dem der Eintritt (2) in die Wendel eintritt, und der Bereich (5), in dem der Austritt (3) aus der Wendel austritt, nicht. Hierdurch werden die Druckverluste des Wärmeaustauschers (1 ) gemindert.

Figure 00000001
In the case of a helical heat exchanger (1) with an inlet (2) and an outlet (3), the area (4) in which the inlet (2) enters the coil overlap when viewed in the direction of the central axis (6) of the coil , and the area (5) in which the outlet (3) exits the helix is not. This reduces the pressure drops in the heat exchanger (1).
