Definitions
- the invention relates to a helical heat exchanger.
- Such heat exchangers are used, for example, in heaters.
- the helical heat exchanger has several spiral circulations, between which there is always a gap. Inside is the helical heat exchanger a burner that burns a hydrocarbon-air mixture. Exhaust gases from the burner flow through the column of the helical heat exchanger, that of the one to be heated Water flows through, and are cooled down. Then the exhaust gases are in collected in an exhaust manifold and derived in an exhaust duct.
- the problem is solved in that the outer Helical revolutions are compressed in the area of the entry or exit. This ensures that the helical heat exchanger approximates the shape of a cylinder.
- Helical heat exchanger according to the prior art have opposite inlets and outlets. This is where the compressed areas of the inlet and outlet on a line parallel to the central axis the helix. While in the remaining area of the heat exchanger a certain number (n) Helical revolutions are next to each other, are in the entry / exit area n + 1 Helical revolutions side by side. For this reason, the constrictions are special large or the cross-sections particularly small, which causes large pressure losses on these Jobs.
- the invention has for its object the pressure losses in a helical To minimize heat exchangers with inlet and outlet.
- the proposed measures avoid being parallel on a line the entry and exit of the central axis of the helix are opposite and thus excessive Constrictions can be dispensed with.
- the features of claim 2 have the advantage that the medium to be cooled can flow between helical revolutions.
- the features of claim 8 have the advantage that the local reduction the width of a pipe in one direction by increasing the width of the same pipe is compensated in the perpendicular direction, so that the cross section is approximately the same remains. This reduces the pressure loss.
- a helical heat exchanger 1 according to FIGS. 1 to 3 according to the prior art has an inlet 2 and an outlet 3. There are several in between Helical revolutions around a central axis 6. The area 4 in which the entry 2 into the helix enters, and the area 5, in which the exit 3 exits the coil, are on a line parallel to the central axis 6 of the helix. The pipes are in areas 4 and 5 narrowed so that the heat exchanger has an approximately cylindrical shape. Between individual spiral revolutions are located in column 7.
- An inventive helical heat exchanger 1 according to FIGS. 4 and 5 differs in that inlet 2 and outlet 3 are offset by 80 °, whereby the Area 4 in which entry 2 enters the helix and area 5 in which exit 3 emerges from the coil, do not lie one behind the other.
- the constrictions 8 are thereby less than in the prior art.
- Fig. 6 shows in area 4, in which the inlet 2 enters the helix an expansion, which is suitable to compensate for the narrowing in such a way that the pipe cross-section is not narrowed.
- FIG. 7 shows an alternative design of a heat exchanger according to the invention see, where the inlet 2 and the outlet 3 are offset by 180 ° and thus in the same Show direction.
