Definitions
- the invention relates to the field of heat exchangers, such as those used for example in automobile construction for cooling an engine. It relates more specifically to the so-called "tube" heat exchanger models comprising several rows of tubes. It also relates to a method of assembling such a heat exchanger.
- the function of a heat exchanger intended for the cooling of an engine is to transmit to an external fluid the heat of a fluid circulating inside 1 exchanger.
- tubes are arranged in which the fluid circulates, placing an upstream chamber and a downstream chamber in communication, the heat exchange between the internal fluid and the external fluid taking place at the surface of the tubes. .
- one row of tubes is in communication with an upstream chamber, and another row of tubes is in communication with a downstream chamber juxtaposed with the chamber upstream, the chambers being arranged near the ends of the tubes.
- each of the tubes of a row in communication with a tube facing the other row, at the ends opposite to those connected to the chambers.
- EP1298401 One solution proposed by EP1298401 is to make an entire row of tubes communicate with the entire row of tubes facing each other.
- a manifold is provided in the form of two assembled half-tubes, provided with connection holes on their internal wall for the passage of the fluid from one half-tube to the other, which each come to cover a row of tubes.
- the contact surface between the manifold and the tubes is too small for satisfactory brazing to be achieved.
- this solution involves a large internal volume of the collector, which affects its resistance to the pressure of the internal fluid, particularly in the case of the use of carbon dioxide C0 2 as internal fluid.
- the object of the invention is in particular to overcome the aforementioned drawbacks by proposing a heat exchanger in which a circulation of the fluid from one tube to the other is ensured by means of an individual plug capable of sealingly housing one end of each tube and having an interior space for the circulation of the fluid, the assembly of the two tubes and of said individual plug ensuring circulation of the fluid along a U-shaped path.
- - Said individual plug comprises two housings, whose shapes are complementary to those of the tubes, which open into said interior space.
- - Said individual plug is made in the form of a stamped part having an outer wall, which envelops the ends of the tubes.
- the outer wall is of substantially constant thickness.
- the outer wall forms roundings, making the individual cap more resistant to fluid pressure.
- the housings are delimited by the external wall of the individual plug.
- the housings are formed in part by a pinching of the outer wall bringing two parts of the inner surface of the outer wall into contact.
- - Said tubes are flat tubes arranged in the same plane.
- the heat exchanger contains carbon dioxide as a fluid.
- the invention also relates to a method of assembling a heat exchanger which comprises the introduction of the two tubes into said individual plug, said individual plug then being pinched so as to adapt its shape to those of the tubes.
- FIG. 1 is a perspective view of a part.ie of a heat exchanger according to the invention
- FIG. 1 is an exploded perspective view of a section of the heat exchanger of Figure 1
- - Figure 3 is a perspective view of an individual plug only.
- the heat exchanger according to the invention comprises, as shown in FIG. 1, an upstream chamber and a downstream chamber in the form of juxtaposed parallel conduits 2,6 in communication respectively with a first set of identical tubes 4 and with a second set of identical tubes 8, in the vicinity of one end thereof.
- the tubes 4 and 8 are flat tubes, arranged two by two side by side along a same plane perpendicular to the axis of the conduits 2 and 6, and having edges of rounded shape.
- Figure 2 shows that the ends, opposite to those communicating with the conduits, of two tubes 4 and 8 arranged side by side are both capped by a common individual plug 10 which ensures the passage of the fluid from tube 4 to tube 8 thus allowing to obtain a U-shaped circulation.
- the individual plug 10 is produced, as illustrated in FIG. 3, in the form of a single stamped part and therefore consists of a single wall 12, of substantially constant thickness, arranged to form the individual plug 10 as a whole. .
- the shape of the individual plug 10 is given by the wall 12 which envelops and exactly matches the ends of the two tubes 4 and 8, while providing an interior space beyond these ends in the longitudinal direction of the tubes 4 and 8 to allow the passage of the fluid.
- the individual plug 10 has a substantially flat shape. It is provided with rounded end faces 14 and 16 whose radius of curvature is adapted to that of the tubes 4 and 8.
- the side faces 18 and 20 are of a length substantially equal to the thickness of the wall 12 , to the width of the two tubes 4 and 8 joined side by side.
- the spacing between the faces lateral 18 and 20 of the individual plug 10 is substantially identical to the thickness of the tubes 4 and 8.
- the bottom 22 of the individual plug 10 also has a rounded shape.
- the interior space is delimited by a part of the end faces 14 and 16 and the bottom 22 of the individual plug 10, and therefore has rounded shapes which make the individual plug 10 more resistant to the pressure of the fluid.
- the internal volume of the individual plug 10 as well as its external dimensions are, thanks to this configuration, reduced to a minimum, which avoids a loss of pressure in the interior space on the one hand and, on the other hand, reduces the bulk. of the heat exchanger itself.
- the small size of the individual plug 10 in thickness reduces the distance required between two tubes connected to the same conduit.
- the nip 24 of the wall 12 is carried out only over part of the depth of the individual stopper 10, so that 'the housings 14 and 16 open into the interior of the individual plug 10 to allow the tube fluid passage 4 to the tube 8.
- the pinching 24 of the wall 12 is however carried out to a sufficient depth to form a contact surface between the housings 26 and 28 and the ends of the tubes 4 and 8 allowing a brazing to be carried out, which ensures the fixing of the tubes 4 and 8 in the housings 26 and 28 as well as the sealing of the individual plug 10.
- the length of the pinch 24 can be adapted (increased or reduced) according to the requirements related to brazing and the depth of the individual plug 10 chosen so as to provide an interior space whose volume is adapted to the flow rate of the fluid in the tubes 4 and 8.
- a preferred method is to introduce the ends of the tubes 4 and 8 into the individual plug 10, which does not yet have pinching 24.
- the individual plug 10 is then pinched so as to form the housings 14 and 16. It only remains to carry out the brazing of the tubes 4 and 8 so as to ensure the fixing and sealing of the plug 10.
- the individual plug 10 can be placed in heat exchangers comprising more than two rows of tubes. Similarly, it is possible to carry out the pinching 24 of the wall 12 before the introduction of the tubes 4 and 8 into the individual plug 10.
