  • the heat exchanger tubing may comprise multiple successive coil tubes having first ends distanced gradually at longer distances from the first end of the core.
  • each coil tube may be the same.
  • a heat exchanger comprising at least one axial divider wall extending between the outer surface of the core and the inner surface of the body and having holes for coil tubes.
  • a heat exchanger comprising at least one radial divider extending from either the outer surface of the core or the inner surface of the body in between the coil tubes creating one or multiple flow paths for the second liquid.
  • FIGURE 1 illustrates a heat exchanger in accordance with at least some embodiments of the present invention.
  • a heat exchanger tubing 2 is arranged around the core 1 and the heat exchanger tubing 2 is forms an outer borderline defining the shape of the heat exchanger tubing 2.
  • the shape of the heat exchanger tubing 2 has a first part 4 formed as a cone and a second part 5 formed as a cylinder.
  • the diameter of the cylinder is the same as the largest diameter of the cone, so these diameters match each other.
  • a body 3 forms the outer casing of the heat exchanger.
  • the outer surface of the body is cylindrical.
  • the heat exchanger may be used even in cold waters having temperature only few degrees above zero, even at a range from 0,5 - 5°C, freezing may be a problem.
  • the second liquid flows on the bottom reservoir 16 of the body 3 and exits via outlet 17.
