Definitions

  • the invention relates to a condenser with integrated tank, suitable for being part of a refrigeration circuit, for example of an air conditioning installation of a motor vehicle.
  • It relates more particularly to a condenser for a refrigeration circuit traversed by a refrigerant, comprising a bundle of finned tubes mounted between two manifolds, and in which one of the manifolds communicates with a tank.
  • the refrigerant in superheated vapor phase is sent, via a compressor, to a condenser in which it is successively cooled or "desuperheated”, condensed into a hot liquid phase, then "under -chilled "in a cold liquid phase.
  • the refrigerant, condensed and cooled is sent, via an expansion valve, to an evaporator where it exchanges heat with an air flow to be sent into the passenger compartment of the vehicle.
  • the refrigerant is transformed into the vapor phase, while the air flow is cooled to supply conditioned air.
  • the refrigerant in vapor phase leaves the evaporator to reach the compressor, and so on.
  • the reservoir which is usually connected at the outlet of the condenser, is produced in the form of a separate container.
  • the object of the invention is in particular to overcome the aforementioned drawbacks.
  • the manifold and the reservoir are delimited by the same tubular casing with tubular wall, which is divided by a longitudinal partition into a collecting compartment (forming the manifold ) into which open the bundle tubes and a reservoir compartment (forming a reservoir) which communicates with the collecting compartment through orifices provided in the longitudinal partition, and in which the longitudinal separation partition has a first longitudinal edge engaged in a slow longitudinal of the tubular wall of the housing and a second longitudinal edge pressed against the tubular wall of the housing, which allows a solder connection between the housing and the longitudinal partition wall.
  • the manifold and the reservoir constitute the two adjacent compartments of the same tubular housing, which in particular makes it possible to reduce the overall size of the manifold-reservoir assembly and to simplify the mounting operations.
  • the division of the tubular housing is carried out simply by a longitudinal partition of separation (also called “separator”), which is connected by brazing to the tubular wall of the housing.
  • the tubular wall of the housing is of generally cylindrical shape. This configuration is optimal for reducing the size of the housing while ensuring maximum resistance to the pressure of the refrigerant. It can be a cylindrical shape with a circular section or with a non-circular section, for example oval.
  • the bundle tubes extend in a non-radial direction relative to the center of the cylindrical section of the tubular wall of the housing.
  • center designates the geometric or mathematical center in the broad sense of the section of the housing, whether circular or non-circular. This allows for easier communication between
  • the tubes and the collecting compartment which should preferably have a volume less than that of the tank compartment.
  • the longitudinal partition wall comprises two planar walls forming an angle between them and comprising respectively the first longitudinal edge and the second longitudinal edge.
  • this longitudinal partition can be easily obtained by longitudinal folding of a metal strip to form a kind of angle.
  • the angle formed between the two flat walls of the longitudinal partition is approximately equal to 90 °.
  • This preferred embodiment of the longitudinal partition is particularly suitable for the case where the wall tubular housing is circular cylindrical in shape. It is then advantageous for the apex of the angle formed between the two flat walls of the longitudinal partition to be situated practically in the center of the circular section of the tubular wall. It follows that the respective cross sections of the collecting compartment and the tank compartment correspond substantially to a quarter and three-quarters of the total cross section of the tubular wall.
  • the condenser comprises transverse partitions which extend in the collecting compartment.
  • each transverse partition has a first part which constitutes the partition itself and which corresponds to the cross section of the collecting compartment and a second part which partially corresponds to the cross section of the tank compartment, these two parts forming a notch between them. suitable for engaging in a corresponding notch formed from the longitudinal edge of the longitudinal partition.
  • the first part of the transverse partition constitutes the partition itself, that is to say the useful part.
  • the second part contributes, on the one hand to delimit the aforementioned notch and, on the other hand, to maintain the longitudinal partition inside the housing.
  • transverse partitions are first fitted onto the longitudinal partition, by cooperation of their respective notches, then the assembly is threaded axially inside the housing. This introduction is carried out so that the first longitudinal edge of the longitudinal partition engages in the longitudinal section of the wall of the housing.
  • the tubular wall of the housing is obtained by winding a metal strip so as to have two longitudinal edges which delimit between them the longitudinal slot of the housing.
  • the longitudinal partition, as well as the transverse partitions are metallic elements coated with a solder plating.
  • the condenser shown in Figure 1 comprises a bundle 10 formed of a multiplicity of flat tubes 12 between which are placed spacers 14 of generally corrugated shape, forming heat exchange fins.
  • the bundle 10 is mounted between a tubular manifold 16 and a tubular housing 18.
  • the manifold 16 and the tubular housing 18 are of circular section and have axes parallel to each other.
  • the manifold 16 includes an inlet tubular 20 and an outlet tubing 22 for a refrigerant.
  • the refrigerant in the form of superheated vapor phase is sent, via a compressor (not shown), to the pipe 20.
  • This fluid is successively cooled or "desuperheated”, condensed into a hot liquid phase, then "under -chilled "in a cold liquid phase, before leaving the condenser via the outlet pipe 22.
  • FIGS. 2 to 4 describe the structure of the tubular housing 18.
  • the housing 18 comprises a tubular wall 24 which has a cylindrical shape of revolution around an axis XX and therefore a circular cross section whose center passes through the axis XX.
  • the wall 24 is obtained by rolling a metal strip, for example made of aluminum or aluminum alloy, so as to provide two longitudinal edges 26 and 28 which delimit between them a longitudinal slot 30 which extends parallel to the generatrices of the wall 24 and which has a width L ( Figure 2).
  • the housing 18 is intended to receive internally a longitudinal partition wall 32 which is shown alone in FIG. 3.
  • This longitudinal wall is obtained by folding a metal strip so as to form two plane walls 34 and 36 forming an angle between them To which, in the example, is substantially equal to 90 °.
  • the walls 34 and 36 are connected to each other by a rounded 38.
  • the angle A has a virtual vertex S.
  • the walls 34 and 36 respectively have a first longitudinal edge 40 and a second longitudinal edge 42.
  • the wall 34 has at least two communication holes 44, only one of which is visible in FIG. 3.
  • the partition 32 has a thickness E slightly less than the width L of the slot 30.
  • the partition 32 is intended to be threaded inside the tubular wall 24, so that the longitudinal edge 40 comes to engage in the slot 30 and that the longitudinal edge 42 comes to bear against the inside of the wall tubular 24, as can be seen in FIG. 4.
  • the partition 32 then delimits in the housing 18 a collecting compartment 46 and a reservoir compartment 48.
  • the top S of the transverse partition is close to the 'axis XX.
  • the cross section of the collecting compartment 46 and that of the tank compartment 48 correspond respectively to a quarter and three-quarters of the total cross section of the tubular wall 24. It is indeed advantageous that the tank compartment occupies more of the half the total volume of the case.
  • the tubes 12 have ends 50 which are introduced into elongated holes 52 formed in the thickness of the tubular wall 24 and in the region corresponding to the collecting compartment 46.
  • the tubes 12 have respective axes YY which extend in a non-radial direction relative to the center of the circular section of the wall 24, and this to facilitate better implantation of the tubes taking into account the configuration of the collecting compartment 46.
  • the compartments 46 and 48 communicate with each other through the aforementioned holes 44.
  • the housing 18 further comprises several transverse partitions 54 as shown in FIG. 5. These partitions here have approximately the shape of a circular sector limited by a circular edge 56 of radius adapted to the interior radius of the tubular wall 24 and extending over three-quarters of a circumference. This partition is further delimited by two radial edges 58 and 60 which form a right angle between them.
  • the partition 54 comprises a first part 62 which extends over a quarter of circumference up to a notch 64 and a second part 66 which extends over a half-circumference between the notch 64 and the edge 58.
  • Part 62 has a shape adapted to that of the cross section of the collecting compartment 46 and therefore constitutes the partition itself, or useful part.
  • the part 66 is intended to bear against the tubular wall 24, without acting as a partition.
  • the longitudinal partition 32 comprises a multiplicity of notches 68 which are intended to cooperate each with a notch 64 of a transverse partition 54.
  • the partitions 54 can be fitted laterally on the longitudinal partition 32, so that the notches 64 correspond respectively with the notches 68.
  • an assembly is formed as shown in FIG. 7. This assembly can then be threaded inside the tubular wall 24, so that the longitudinal edge 40 of the longitudinal partition 32 comes to slide in the slot 30 and that the longitudinal edge 42 of the longitudinal partition 32 automatically bears against the inside of the tubular wall 24. It is thus ensured that the longitudinal partition 32 and that the transverse partitions 54 are perfectly in position.
  • the opposite ends of the tubes 12 can in turn be introduced into suitable holes in the wall of the manifold 16.
  • the condenser of FIGS. 8 and 9 is similar to that of FIG. 1.
  • the housing 18 houses a longitudinal partition 32 provided with two communication holes 44 and two transverse partitions 54 and it is closed by two end plates 70 and 72.
  • the manifold 16 houses two transverse partitions 74 and 76 and it is closed by two end plates 78 and 80. As a result, the refrigerant can circulate in the condenser in several successive passes.
  • the various parts making up the condenser in particular the housing 18, the longitudinal partition 32 and the transverse partitions 54, are coated with a solder plating.
  • the latter can be placed in an appropriate oven for brazing.
  • the invention thus makes it possible to produce a condenser in which the tank and one of the manifolds are delimited by the same compact structure and whose assembly can be easily obtained by soldering.
  • the invention also makes it possible to solve the problem of setting up transverse partitions which usually requires delicate crimping operations.
  • the condenser of the invention allows different types of circulation of the refrigerant. It allows in particular the refrigerant to enter and leave the tank before being sub-cooled in the condenser, or even to leave the condenser before entering and leaving the tank.
  • the invention is particularly intended for condensers of air conditioning systems of motor vehicles.
