Definitions

  • the present invention relates to a heat exchanger of the type known as a tube bundle, that is to say the tubes of which are engaged in dissipators and in at least one collecting plate.
  • the invention relates to those of these exchangers whose sets of tubes open into two separate chambers of a water box connected to a collector plate which is retained in leaktight manner on a seal formed from a sheet of elastic material additionally delimiting sockets which seal between the collector plate and the end of the tubes.
  • the invention creates means by which the pressure drop is limited to a predetermined threshold so that the drawbacks mentioned in the foregoing are eliminated.
  • the tube bundle heat exchanger of which sets of tubes are connected to at least one collecting plate, the face of which faces a water box is covered by a sheet of elastic material forming sockets for the ends.
  • tubes and a seal for the water box is characterized in that, in the application to a multiple pass exchanger, the water box is provided with at least one partition delimiting chambers and in that the partition has at least one lumen normally closed by a valve coming from the tablecloth.
  • FIG. 1 schematically illustrates a heat exchanger, for example a cooling radiator of the type with two methodical passes. Consequently, the radiator comprises sets of tubes 1, 1a which open into water boxes 2, 3 mounted in collecting plates 4, 5 which are covered, over their entire surface facing the inside of the water boxes, by plies 6, 7 made of flexible and elastic material. The plies 6, 7 delimit sockets 8 intended to seal with the external wall of each end of the sets of tubes 1, 1a.
  • the layers 6, 7 also form a peripheral seal 9 intended to seal with the peripheral edge 2a, 3a of the corresponding water box.
  • one of the water boxes for example the water box 2 is separated into two compartments 10, 11 by a partition 12 extending longitudinally in the example shown.
  • the circulation fluid which must pass through the tubes of the heat exchanger circulates as illustrated by the arrows, that is to say, for example, from the compartment 10 passing through the tubes 1 then, at from the water box 3, the fluid is brought back by the tubes 1a into the compartment 11 to be reused.
  • At least one opening 13 is provided in the partition 12 and the ply 6 forms, opposite this opening, a valve 14.
  • the valve 14 is reinforced by one or more ribs 15 which 'extends on the face opposite to that facing the light 13 between the sockets 8.
  • valve 14 provides a good seal with the partition 12, it has, at its periphery, a bead or a thin lip 16.
  • the valve 14 is an integral part of the ply 6, that is to say that it comes into molding with the latter at the same time as the sockets 8 and the peripheral seal 9.
  • the collector plate 4 has, as illustrated in the drawing, a longitudinal groove 17 in which the foot of the partition 12 is retained, it is advantageous that the ply 6 is not molded to initially match the groove 17 and, moreover, it it is advantageous for the valve 14 to be molded so that it extends slightly obliquely as long as the water box is not placed on the collecting plate.
  • the speed of circulation of the fluid inside the exchanger is such that it generates unacceptable pressure drops; this may be the case, for example, for a radiator for cooling the liquid circulating in a heat engine whose water pump would be driven at excessive speed.
  • valve 14 As soon as this pressure differential is sufficiently reduced, the elasticity of the valve 14 means that it again closes the lumen 13 to which it corresponds.
  • valve 14 is advantageously molded so that it is slightly inclined but in the opposite direction to that shown in FIG. 4 so that it is normally applied against the partition 12 when the water box 2 is put in place.
  • the invention is not limited to the embodiment, shown and described in detail, because various modifications can be made without departing from its scope.
  • it can be implemented in the same way in a heat exchanger not comprising the water box 3 illustrated in FIG. 1.
  • the sets of tubes 1, 1a are then constituted by bent hairpin tubes.
