  • the vortex generators are embossed in both opposite pipe walls and protrude inwards into the coolant flow.
  • the rows of vortex generators on one flat tube side are offset in the flow direction compared to the rows on the other flat tube side.

  • the opposing structural elements or rows can also be offset from one another in the direction of flow, but only to the extent that there is still an overlap.
  • Structural elements that protrude from one and the other heat exchanger surface and protrude into the flow channel thus simultaneously intervene in the flow and cause a swirling of the flow, which results in an improvement in the heat transfer on the inside of the flow channel.
  • a soot deposits prevented.
  • the pressure loss is kept within reasonable limits.
  • the flow within the flow channel is thus disturbed from both sides at the same time, ie both boundary layers are detached at the same time, which leads to a particularly strong turbulence.

  • the structural elements can be straight or curved, ie with a constant or variable outflow angle to the flow direction.
  • the change in the outflow angle from a relatively large inflow angle to the outflow angle results in a “gentle” deflection of the flow and thus a somewhat reduced pressure loss.
  • the structural elements can be arranged offset within a row, ie the Although structural elements are arranged in a row running transversely to the flow direction, they are staggered in the flow direction, which also results in the advantage of a lower pressure loss.
