Definitions

  • the invention relates to a heat exchanger for heating or cooling a secondary liquid from a primary fluid circulating in at least one helical tubular coil disposed in at least one exchange cavity in which the secondary liquid circulates.
  • Such a heat exchanger can for example be used as a heat pump condenser for heating the water of a swimming pool.
  • FR-2,686,408 thus describes an example of such a coil heat exchanger, which comprises spacers in the form of longitudinal strips, forming housings for the coils of the coil.
  • spacers indeed make it possible to center the coil in the exchange cavity and to optimize the circulation of the secondary liquid around the coils of the coil.
  • US Patent 1893484 describes a coil heat exchanger and helical spacing ribs.
  • the invention therefore aims in general to provide a coil heat exchanger (s) whose thermal performance-especially the heat output restored- are improved over prior exchangers, and this, for equivalent or reduced overall dimensions.
  • the invention aims more particularly to achieve this goal simply and economically, and without otherwise adversely affect the other qualities of the exchanger (service life, ease of installation, ).
  • the spacers comprise at least one tangential rib of helical shape and this tangential helical rib and this coil have different winding directions so as to be in contact with zones of essentially one-off contacts.
  • the inventors have indeed found that this particular structure makes it possible to improve considerably and unexpectedly the thermal performance of the exchanger. In particular, the inventors have found an improvement of 5% to 10% of the heat power of the exchanger. No clear explanation can be given by the inventors to this result.
