Description
Technical Field
The present invention relates to a heat exchanger, in particular for assembly in a motor vehicle.
Background
Motor vehicle heat exchangers typically comprise tubes in which a heat transfer fluid is circulated, and heat exchanger elements, also called fins, connected to the tubes.
The heat exchanger also includes two header tanks that are in fluid communication with the tubes by being connected to opposite ends of the tubes, respectively. The tubes are retained by a collector plate which closes each header tank. The connection between the tube and the collector plate is in most cases achieved by brazing.
In use, a heat transfer fluid is circulated through the tubes from one header tank to another so that the fluid exchanges heat with ambient air in contact with the tubes and fins to raise or lower the temperature.
As a result, the tubes are periodically heated or cooled, which causes them to shrink or expand, which itself creates stress at the joint between the tube and the collector plate. The stresses originate from fatigue, which is substantially borne by the end of the pipe where the connection to the collector plate is located.
In order to limit the effect of said fatigue on the robustness of the tubes without having to increase the thickness of their walls, which would considerably increase the weight of the exchangers, it has been envisaged in the prior art to provide them with reinforcing means. The reinforcing means is typically inserted into the tube, near the connection between the tube and the collector plate.
Document US2007/131404 thus discloses a heat exchanger for a motor vehicle, the tubes of which are provided with stiffening means for being arranged inside the tubes and thus consisting of two fins having a form complementary to the inner surface of the tube wall.
The reinforcement means allow the fatigue to which the end of the tube is subjected to be limited under the effect of the stresses due to thermal deformations. However, when they are placed inside the tubes, the reinforcing means limit the portion of the fluid passage in the tubes, which causes undesirable pressure losses in the heat exchanger, thus reducing its performance.
SUMMERY OF THE UTILITY MODEL
It is therefore an object of the present invention to provide a reinforcement device for the ends of tubes, which reinforcement device does not cause any pressure loss in the heat exchanger.
To this end, the utility model relates to a heat exchanger, include:
-a tube bundle;
-a header tank connected to the tubes;
-at least one collector plate closing the header tank and into which the tubes open;
-a bundle of cooling fins; and
-a reinforcement device for at least one tube,
characterised in that the stiffening means is connected to the outer surface of the at least one tube in a region which is free of fins and which extends between the collector plate and the envelope surface of the fin bundles.
By placing the stiffening means on the outer surface of the tube, the means do not generate any pressure losses in the area where there are no fins and which extends between the collector plate and the envelope surface defined by the bundles of fins, since they are not inside the tube.
In other words, the present invention allows the available space between the collector plate and the fin bundles to be effectively used for inserting the tube reinforcement device therein.
Each tube of the bundle is preferably provided with stiffening means.
According to an advantageous embodiment of the invention, which allows to provide reinforcing means for reinforcement on an already assembled heat exchanger, the reinforcing means comprise at least one reinforcing element in the shape of a "U", comprising one groove and two legs, which overlaps a tube having a form generally complementary to the reinforcing element.
The tube comprises two large sides and two small sides. The legs of the reinforcing element are preferably parallel to each other and the groove of the U abuts against the small side of the tube.
The legs of the stiffening element preferably follow the shape of the collector plate.
According to an advantageous embodiment of the invention, which allows to provide reinforcement means for further reinforcement on an already assembled heat exchanger, the reinforcement means comprise at least one reinforcement member, which is common for a plurality of tubes, the common reinforcement member having a form limiting the overall interaction of the reinforcement elements, each reinforcement element overlapping a tube.
The reinforcement means preferably comprises at least two reinforcement elements arranged on the same tube.
According to a particular embodiment of the invention, two reinforcement elements are arranged opposite each other on the outer surface of the same tube, so that the respective ends of their legs are connected and the reinforcement elements both form a reinforcement around the tube.
According to a particular embodiment of the invention, two reinforcing elements are arranged opposite each other on the outer surface of the same tube, so that the respective ends of their legs are spaced apart.
According to an advantageous embodiment of the invention, which allows to increase the strength of the tube while facilitating the provision of stiffening means on the already assembled heat exchanger, the fins are distributed so as to define secondary envelopes separated by the tube, the stiffening element comprising a heel which extends partially between two consecutive secondary envelopes.
The reinforcing means are preferably brazed to the tube.
In order to limit the weight of the heat exchanger, the tube bundles, the fin bundles and the stiffening means are preferably realized by an alloy mainly comprising aluminum.
An alloy comprising mainly aluminium is understood to be an alloy comprising a majority of moles of aluminium.

Detailed Description
Fig. 1 and 2 show a heat exchanger according to an embodiment of the present invention, which is designated by the general reference numeral 10.
The heat exchanger 10 is intended to be fitted in a motor vehicle.
The heat exchanger 10 comprises tubes 12, the tubes 12 being substantially rectilinear and a conventional heat transfer fluid for circulation therein, and heat exchanger elements, also called fins, connected to said tubes 12.
In the embodiment of the invention shown in fig. 1, the tube 12 comprises a cross-section having the general form of a rounded rectangle. The tubes 12 are arranged substantially parallel to each other and aligned so as to form a single row.
Thus, each tube 12 comprises two large sides and two small sides, and as can be seen in fig. 1, the fins extend between the large sides of two consecutive tubes 12. In the figures, the fins are only shown by the space they occupy in the heat exchanger 10.
In a known manner, the fins comprise fluid breakers having a substantially rectangular shape and arranged transversely with respect to the axis of the tubes 12 between the tubes 12, so as to form a large heat exchanger surface between each tube 12 and the outside air. In this way, the fins are preferably connected to the outer surface S of the wall of the tube 12 on the one hand and to the outer surface S of the wall of the continuous tube 12 on the other hand.
The envelope surface E of the fin bundles can be defined in this way. More specifically, since the heat exchanger 10 comprises a plurality of tubes 12 and a plurality of fins, it is possible to define a secondary envelope E divided by the tubes 12 and in which the fins are distributedS。
The heat exchanger 10 also includes a header tank 14 in fluid communication with the tubes 12.
The header tank 14 here consists of a header tank 16, which header tank 16 is closed by a plate 18, usually called collector plate.
The tubes 12 are connected by their ends to a header tank 14, the header tank 14 being normally interlocked in interlocking holes arranged in said collector plate 18. The tubes 12 thus each lead to a collector plate 18.
The heat exchanger 10 also comprises, in a zone Z, which is free of fins and extends between the collector plate 18 and the envelope surface E defined by the fin bundles, reinforcing means 20 for at least one tube 12, which is connected to the outer surface S of the tube 12.
For this purpose, the reinforcing device 20 is, for example, brazed to the tube 12.
In order to reduce the weight of the heat exchanger 10, together with the tubes 12 and fins, the stiffening means 20 is preferably realized by an alloy, which mainly comprises aluminium. It is noted here that an alloy comprising mainly aluminium is understood to be an alloy comprising a majority mole of aluminium.
In all the embodiments shown in the figures, the reinforcing means 20 comprise at least one reinforcing element 22, the reinforcing element 22 being provided with legs 24 so that the reinforcing element 22 has a substantially U-shape, which overlaps the profile of the tube 12, having a general form complementary to the reinforcing element 22.
The reinforcing element 22 of the heat exchanger 10 according to the first embodiment of the invention is shown separately in fig. 3.
In all the embodiments shown in the figures, and as can be seen in fig. 1 and 2, the legs 24 of the reinforcing element 22 are parallel, and the groove of the U rests against the small side of the tube.
Thus, the profile of the tube 12 overlapped by the reinforcing element 22 comprises a small side of the tube and a portion of each of the two large sides, the legs 24 being in planar contact with the large sides of the tube 12.
The reinforcing means 20 of the tube 12 preferably comprise two reinforcing elements 22 arranged on the outer surface S of said tube 12 so as to overlap opposite sides of the tube 12, as can be seen in fig. 1 and 2.
More specifically, in the first embodiment of the invention, and as can be seen in fig. 2, two reinforcing elements 22 are arranged opposite each other on the outer surface S of the tube 12, so that the respective ends 26 of their legs 24 engage such that the reinforcing elements 22 all form a reinforcement around the end of the tube 12.
In contrast, in the second embodiment of the reinforcing element 22 according to the invention shown in fig. 4, two reinforcing elements 22 are arranged opposite each other on the outer surface S of the tube 12, so that the respective ends 26 of their legs 24 are spaced apart.
As can be seen in said fig. 4, it is preferably also provided that the legs 24 of each stiffening element 22 follow the shape of the collector plate 18.
To further strengthen the tube 12, the stiffening means 20 may be partially on the two auxiliary envelopes ESExtending therebetween.
To this end, the stiffening element 22 may comprise a heel 28, as can be seen in fig. 1, the heel 28 being partially in two auxiliary envelope surfaces ESExtending therebetween.
Thus, the portion of the outer surface S of the tube 12 located between the fins, which is free to receive a portion of the reinforcing element 20, is effectively utilized. The heel 28 particularly allows the tube 12 to be further reinforced.
As can be seen in particular in fig. 3, the heel 28 is, for example, a projection extending from a portion of a connecting piece 30, the connecting piece 30 connecting the legs 24 of the reinforcing element 22 in a manner perpendicular to the direction of extension of the legs 24. More specifically, heel 28 extends along a small side of tube 12 that overlaps with reinforcing element 12.
The reinforcing element 22 may also be of other forms.
Thus, as shown in fig. 5, in a third embodiment of the stiffening element 22 according to the invention, the stiffening element 22 does not comprise a heel 28.
The form of the legs 24 of the stiffening element can also be spread out according to the form of the collector plate 18.
Thus, as shown in fig. 1 to 3, in the first embodiment of the stiffening element 22 according to the invention, as shown in fig. 5 in the third embodiment of the stiffening element 22 according to the invention, the outer edge 32 of each leg 24 of the stiffening element 22 is curved and complementary to the curved shape of the collector plate 18.
As shown in fig. 6, in a fourth embodiment of the reinforcement element 22 according to the present invention, the legs 24 of the reinforcement element 22 have a substantially rectangular shape. Thus, the outer edges 32 of each leg 24 of the stiffening element 22 are parallel.
As shown in fig. 7, in a fifth embodiment of the reinforcement element 22 according to the invention, the reinforcement means 20 comprises at least one reinforcement member 34, which reinforcement member 34 is common to a plurality of tubes 12, the reinforcement member 34 having a form limiting the overall interaction of the reinforcement element 22, the legs 24 of the reinforcement element 22 each overlapping a tube 12.
In other words, the reinforcement members 34 are constituted by the reinforcement elements 22, the reinforcement elements 22 being connected to each other so as to form a serpentine or even castellated whole, the turret (turret) of which will be formed by the connecting member 30.
In said fifth embodiment of the reinforcement element 22 according to the present invention, each reinforcement element 22 comprises a heel 28 in the same way as the reinforcement element 22 shown in fig. 3.
Furthermore, the outer edge 32 of each leg 24 of each stiffening element 22 is curved and complements the curved shape of the collector plate 18 in the same way as the stiffening element 22 shown in fig. 5.
As shown in fig. 5, in a sixth embodiment of a reinforcing element 22 according to the present invention, none of the reinforcing elements 22 of the common reinforcing member 34 comprises a heel portion 28. Furthermore, the outer edge 32 of each leg 24 of each stiffening element 22 is parallel in the same way as the stiffening element 22 shown in fig. 6.
In an embodiment of the invention, not shown, each tube 12 is provided with a reinforcing device 20.
The invention is not limited to the embodiments shown and other embodiments will be apparent to those skilled in the art.
The present invention relates to any combination of embodiments such as those shown. Thus, a heat exchanger may be envisaged in which some tubes are provided with stiffening means comprising stiffening means with a heel, while other tubes will be provided with stiffening means comprising stiffening means without a heel.
The present invention also relates to a heat exchanger comprising two reinforcing members connected to the outer surface of the tube such that the reinforcing elements of their confinement overlap the relative profile of the tube.
In that case, the respective ends of the legs of the stiffening element may be connected such that the stiffening element forms a stiffener which is thus overlapped around the pipe, or may be spaced apart instead.
