Definitions

  • the present invention relates to the field of thermal batteries and more specifically of thermal batteries comprising a phase-change material.
  • Thermal batteries are generally used for heating the vehicle interior, notably in electric and hybrid vehicles or for preheating a heat-transfer fluid in a thermal management circuit. Thermal batteries may also be used for preheating the engine oil or the automatic transmission fluid of vehicles with an internal combustion engine.
  • a thermal battery with phase-change materials generally comprises an enclosure forming a reservoir inside which the phase-change material is placed, generally in encapsulated form.
  • the performance of the thermal battery is thus dependent on the quantity of phase-change material that it is able to contain, coupled with the need for the fluid to circulate within the reservoir with the lowest possible pressure drops.
  • One of the objects of the present invention is therefore to at least partially overcome the disadvantages of the prior art and to propose an improved thermal battery.
  • the present invention therefore relates to a thermal battery comprising an enclosure comprising a fluid inlet and outlet and comprising within it an encapsulated phase-change material in the form of at least one tube, at least one tube being wound in a spiral within the enclosure.
  • the spiral winding of the tube is performed about an axis of winding parallel to the circulating flow of the fluid within said thermal battery.
  • the spiral winding of the tube comprises an empty central part along the axis of winding.
  • the thermal battery comprises longitudinal tubes of encapsulated phase-change material, said longitudinal tubes being positioned in the central part of the spiral winding of the tube.
  • the longitudinal tubes therefore fill in the central part of the spiral winding and thus further increase the quantity of phase-change material contained within the thermal battery.
  • the thermal battery comprises spacers between the tubes so as to create a space for the circulation of the fluid.
  • the spiral winding of the tube is performed using a single tube.
  • the walls of the tube are made of plastic.
  • FIG. 1 is a schematic perspective depiction of the arrangement of the tubes of encapsulated phase-change material within a thermal battery according to a first embodiment
  • FIG. 2 is a schematic perspective depiction of the arrangement of the tubes of encapsulated phase-change material within a thermal battery according to a second embodiment.
  • a thermal battery 1 generally comprises an enclosure (not depicted), preferably thermally insulated, comprising a fluid inlet and a fluid outlet.
  • An encapsulated phase-change material in the form of at least one tube 3 is placed inside the enclosure. As FIGS. 1 and 2 show, at least one of the tubes 3 is wound in a spiral and arranged within the enclosure.
  • the spiral winding of this tube 3 is performed about an axis of winding A which is parallel to the circulating flow of the fluid (indicated by arrows in FIGS. 1 and 2 ) within said thermal battery 3 so that the fluid can circulate perpendicular to the spiral winding.
  • the spiral winding within the thermal battery 1 is preferably performed using a single tube 3 . That makes it possible to limit the number of ends. Specifically, at each of its ends a tube 3 containing a phase-change material has a weld or a plug in order to encapsulate said phase-change material. Limiting the number of tubes 3 and, therefore, the number of these ends makes it possible to reduce the risks of leakage of the phase-change material.
  • the tube 3 inside which the phase-change material is encapsulated is preferably made of plastic so as to allow this spiral winding.
  • the spiral winding has an empty central part 5 along the axis of winding A.
  • This central part may remain empty in order to ensure good circulation of the fluid as illustrated in FIG. 1 .
  • a minimum bend radius without said tube 3 kinking is of the order of 25 mm.
  • the empty central part 5 will then have a diameter of the order of 50 mm.
  • this central part 5 may be filled in with longitudinal tubes 7 of encapsulated phase-change material. These longitudinal tubes 7 are then positioned parallel to the axis of winding A.
  • These longitudinal tubes 7 therefore fill in the central part 5 of the spiral winding and thus further increase the quantity of phase-change material contained within the thermal battery.
  • the tubes 3 and 7 may comprise spacers so as to create a space for the circulation of the fluid.
  • the thermal battery 1 is optimized because of the special spiral layout of at least one tube 3 of phase-change material that makes it possible to maximize the quantity of phase-change material.
