  • the or each internal duct (for example made of a metallic material of high thermal conductivity, such as aluminum) may be provided more thermally conductive than the outer tube, which may be less generally thermally conductive because of of the material (typically metallic) which constitutes it and / or of a thermally insulating coating (for example of reinforced plastic material) of which this external tube (for example based on aluminum) can be provided.
  • the low-pressure fluid exchanges heat with the outside of the internal heat exchanger.
  • the exchanger may be an internal heat exchanger for a motor vehicle air-conditioning circuit comprising two low and high pressure portions traversed by a refrigerant circulating at high pressure in said at least one a conduit and, at low pressure, around said at least one conduit within the outer tube.
