Definitions

  • the invention relates to the field of sectional heat exchangers for use in a heat cell.
  • Such heat exchangers comprise several segments.
  • the number of segments is selected as a function of the required capacity of the sectional heat exchanger.
  • the sectional heat exchanger of the invention has a combustion chamber in which a burner can be installed - thereby forming a heat cell - for the generation of flue gas that will transfer its thermal energy to heat water.
  • Such heat cells can be used in boilers.
  • Sectional heat exchangers are built up of a number of sections or segments.
  • Sectional heat exchangers e.g. out of aluminium, exist that comprise a number of identical intermediate segments positioned next to each other; and two end segments.
  • the number of intermediate segments that is used in the assembly of the heat exchanger depends on the required capacity of the heat exchanger.
  • the heat exchanger has a number of channels - at least one channel in each intermediate segment - in parallel flow connection for water to be heated, and flue gas channels extending from the one or more than one combustion chambers in the heat exchanger.
  • a sectional heat exchanger, using cast intermediate segments, is provided in DE102005014616B3 , in which one single burner can be mounted in the one combustion chamber of the sectional heat exchanger.
  • GB2441183A discloses a sectional heat exchanger according to the preamble of claim 1 and shows a heat exchanger for use in a condensing boiler comprising a plurality of heat exchanger sections having at least one internal flow passage with an inlet and an outlet for the passage of a heat exchange medium and a plurality of elongate fins on at least one side of each section defining flue gas flow channels, a burner to produce hot flue gas, a means to guide the flue gas from the burner through the flow channels from a primary part to a secondary part of the heat exchanger, and a means to promote unidirectional flue gas flow before entering the primary part.
  • Promotion means may be a U-shaped barrier that changes the flue gas from a radial to the unidirectional flow and also changes from a downward to an upward flow.
  • the promotion means may comprise a plurality of elongated fins disposed between, and parallel to, vertical arms of the U-shape.
  • the primary object of the invention is to provide sectional heat exchangers that are less prone to boiling when used in heat cells for boilers.
  • the invention is a sectional heat exchanger for a condensing heat cell according to claim 1.
  • the sectional heat exchanger comprises two end segments and one or more than one intermediate segment(s) provided between the two end segments.
  • the one or the more than one intermediate segment(s) and the two end segments are assembled in the heat exchanger.
  • a combustion chamber is provided in the sectional heat exchanger, preferably perpendicular to the one or to the more than one intermediate segment(s).
  • Each of the one or the more than one intermediate segment(s) comprises at least one water flow channel for water to be heated. In between each two consecutive segments - between two intermediate segments if more than one intermediate segment is provided as well as between intermediate segments and end segments - at least one flue gas flow channel is provided, extending from the combustion chamber.
  • the one or the more than one intermediate segment(s) each comprise a horizontal row of ribs extending into the flue gas flow channel in order to increase heat exchange from the flue gas to the water to be heated. Ribs at the two outer sides of the horizontal row of ribs have a larger height than ribs in the middle of the row of ribs. With height of the rib is meant the dimension of the rib in the vertical direction of the sectional heat exchanger.
  • the more than one intermediate segment(s) each comprise a plurality of rows of pins extending in the flue gas channel to increase heat transfer.
  • each row of pins is provided in serial flue gas flow direction.
  • the pins have a circular cross section.
  • the rib has a substantially rectangular cross section, with its largest side aligned in the vertical direction of the heat exchanger. More preferably, the substantially rectangular cross section is a rectangular cross section having rounded edges.
  • the sectional heat exchanger of the invention has the surprising benefit that boiling of water in the water flow channels is prevented. This benefit is believed to be achieved thanks to the modified heat exchange at the horizontal row of ribs because of the differences of height of the ribs. The lower height of the ribs in the middle of the row of ribs will obviously involve a reduced heat transfer, negative for efficiency of the heat exchanger.
  • the intermediate segment is provided such that parallel flows of flue gas flow along all of the ribs of the horizontal row of ribs.
  • Meant is that no gas flow flows first along one rib of the horizontal row of ribs and then in serial flow arrangement along another rib of the horizontal row of ribs.
  • the height over width ratio of each of the ribs of the horizontal row of ribs is more than 2.

  • the two end segments each comprise only one row of ribs extending into the flue gas flow channel in order to increase heat exchange from the flue gas to the water to be heated.
  • the one or the more than one intermediate segment(s) and/or the two end segments are aluminium or aluminium alloy segments, preferably separate segments.
