Definitions

  • the present invention relates to the field of heat exchanger and in particular to heat exchangers intended to be traversed by a fluid under high pressure.
  • the invention relates more particularly to air conditioning evaporators capable of being traversed by a refrigerant fluid in the supercritical state, as is the case for natural gases such as carbon dioxide, also known as CO2 or R744.
  • Such heat exchangers find particular application in motor vehicles.
  • the invention relates to a header box as defined in the preamble of claim 1, and as disclosed in JP 2009275956 .
  • a known fluid refrigerant circuit forms a closed loop in which the refrigerant fluid flows in order to dissipate or collect calories through heat exchangers.
  • the heat exchanger comprises a header box to connect said heat exchanger to the fluid refrigerant circuit, said header box linking pipes from the fluid refrigerant circuit to the heat exchanger core, in order for the refrigerant fluid to flow through heat exchanger tubes.
  • this refrigerant fluid In a fluid refrigerant circuit traversed by a refrigerant fluid in the supercritical state, this refrigerant fluid remains essentially in the gaseous state and under a very high pressure, which is usually around 100 bars. As a result, heat exchangers must be able to withstand such high pressure, the recommended burst pressure being generally three times the value of the nominal operating pressure, burst pressure thus reaching around 300 bars.
  • This known heat exchanger comprises the header box, a tank and the heat exchange tubes allowing the refrigerant fluid to migrate between the header box and the tank.
  • the heat exchange tubes also allow a thermal exchange between the refrigerant fluid, flowing inside said heat exchange tubes, and an air flowing outside the heat exchanger, thus capturing calories from the air flowing across the heat exchanger core.
  • the header box comprises a first manifold intended to receive the refrigerant fluid from the fluid refrigerant circuit and a second manifold intended to inject the refrigerant fluid from the heat exchanger back into the fluid refrigerant circuit.
  • the header box comprises a cover, a header plate and a distribution plate localized between the cover and the header plate.
  • the cover of the header box is configured to delimit said header box.
  • the header plate of the header box is designed to allow the refrigerant fluid to flow between the first manifold or the second manifold and the heat exchange tubes.
  • the distribution plate is intended to allow the refrigerant fluid to flow between a connector connected to said distribution plate and the header plate.
  • the cover, the distribution plate and the header plate are brazed together to insure the sealing of the header box, avoiding leaks of the refrigerant fluid.
  • the header plate comprises teeth configured to secure the assembly of the header plate, the distribution plate and the cover together, in order to help the brazed header box to withstand the very high pressure generated into the fluid refrigerating circuit.
  • the header plate, the distribution plate and the cover are common to the first manifold and the second manifold of the header box.
  • This configuration induces a thermal coupling between the first manifold and the second manifold of the header box, thus reducing the thermal efficiency of the heat exchanger, some thermal energy being wasted by a direct transfer from the first manifold to the second manifold, without being used through the heat exchange core of the heat exchanger.
  • the invention aims at proposing a header box with a specific design in order to limit the thermal coupling between its first manifold and is second manifold, while still resisting to the very high pressure resulting from the use of the super-critical refrigerant fluid.
  • the invention also aims at proposing a heat exchanger comprising such a header box.
  • the invention finally aims at proposing a fluid refrigerant circuit that comprise such a heat exchanger, as well as natural fluid refrigerant.
  • a first object of the invention is a header box for a heat exchanger according to claim 1.
  • some of the linking elements of the header box are thus localized between the first manifold and the second manifold.
  • This configuration creates a gap between said first manifold and second manifold, said gap allowing a thermal decoupling between the first manifold and the second manifold. More precisely, the header plate of the first manifold is separated from the header plate of the second manifold by the gap. Similarly, the distribution plate of the first manifold and the cover of the first manifold are separated, by the gap, from the distribution plate of the second manifold and the cover of the second manifold, respectively.
  • Such configuration thus allows an improved thermal efficiency of the header box, less calories being transferred directly between the first manifold and the second manifold compared to a known configuration of a header box.
  • the mechanical link allows the first manifold to keep its relative position compared to the second manifold.
  • Each manifold comprises two lines of linking elements, localized on each longitudinal side of the related manifold.

  • This configuration allows said heat exchanger to have an improved thermal efficiency thanks to the header box according to the invention.
  • the header box according to the invention reduces the thermal coupling between the first manifold and the second manifold. Thus, more heat can be captured through heat exchange tubes of the heat exchanger.

More particularly, the grooves 140 of the first cover 13 and of the second cover 14 allow the openings 130 of the distribution plate 12 to be fluidically connected to the windows 125 of the distribution plate 12 from the first longitudinal end 61 to the second longitudinal end 62 of the distribution plate 12, thus creating the fluid refrigerant circulation inside the header box 1.
  • the invention is not limited by the shape of organs or elements as described here, and covers any shape as long as described here, and covers any shape as long as a header box comprises a gap between a first manifold and a second manifold in order to reduce the thermal coupling between the first manifold and the second manifold, while keeping a mechanical link between the two manifolds.
