Definitions
- the invention relates to heat exchangers, in particular for motor vehicle.
- It relates more particularly to a manifold for a brazed heat exchanger comprising walls which define a room, one of the walls of the room being provided with an opening, a tube being connected to this opening.
- the collecting plate also called a hole plate, has a multiplicity of holes in which the ends are received of tubes which constitute the bundle of the heat exchanger heat. These tubes are associated with fins contributing to increase the heat exchange surface.
- the plaque collector is formed by a wall which delimits a chamber communicating with the tubes to allow circulation of a heat transfer fluid in the bundle.
- One of the walls of the room is provided with at least one tubing to allow the inlet or outlet of the heat transfer fluid.
- Brazed heat exchangers include a bundle mounted between two manifolds.
- the beam is formed of a multiplicity of tubes arranged parallel to each other and alternating with dividers.
- These dividers are of wavy type, i.e. they are formed from a metal strip deformed to form corrugations.
- a spacer disposed between two adjacent tubes comes into respective contact of the two tubes by regions end of the corrugations.
- the heat exchanger further comprises two cheeks, also called crosspieces, which frame the beam and are arranged parallel to the tubes.
- the different parts are formed from a metallic material coated on the outside of a brazing alloy.
- the present invention aims to provide a box collector, and a heat exchanger comprising such a box, which allow quick and little temporary fixing expensive tubing in an opening in a wall of the manifold.
- the tubing has at least one lug and that the orifice has at least one notch allowing passage of the lug of the tubing. So, during soldering, the tubing can be temporarily held in the opening by the lug (s) after rotation of the tubing in the opening.
- Tubing is introduced manually or automatically in the opening, the lug (s) being placed in look at the corresponding notches on the periphery of the opening. Then the tubing is turned angularly from a certain angle so that the lug or lugs are no longer opposite the notches. So the tubing is temporarily maintained on the manifold stably during the passage of the exchanger in the furnace.
- the tubing comprises at least two lugs.
- the tubing has three pins arranged at 120 ° one of the other.
- the opening will then also include three notches arranged at 120 ° from each other.
- the number of notches is equal to the number of pins on the tubing, but this feature is not essential.
- the number of notches can also be a multiple of number of pins. We can imagine for example that the opening has six notches arranged at 60 ° from each other, this which would limit the required angle of rotation to introduce the pins in the notches.
- the tubing is bent and should extend into a given direction to be fitted with a conduit flexible. In this case, it is necessary to respect a precise angular orientation of the tubing relative to the manifold. If the tubing is mounted manually, the wall of the chamber which has the opening is preferably provided with a stop which limits the rotation of the tubing by cooperation with a lug.
- the manifold includes a first part 10 and a second part 12, each formed from a metal sheet, advantageously aluminum, which is shaped by conventional cutting operations and stamping.
- the first part 10 has a bottom 14 which is generally flat and elongated rectangular shape.
- This background 14 is intended to constitute the collecting plate, also called “hole plate”, from the manifold.
- This background features for this purpose a plurality of spaced holes 16 of shape elongated intended to receive tubes 18 forming part of the heat exchanger harness. In the example described, it these are flat tubes 18 between which are arranged fins 20 produced in the form of corrugated spacers.
- Part 10 further comprises two lateral flanks 22 folded opposite, and which are generally flat and parallel to each other. These flanks connect substantially perpendicular to the bottom 14 by two fold lines 24 which are parallel to each other.
- the lateral flanks 22 have extensions in their central part 26 and 28 respectively. Extension 26 has an opening 30 while the extension 28 is completely closed.
- the opening 30 is circular in shape and is intended for allow the adaptation of a tubing 32 of circular section.
- the second part 12 fits on the lateral flanks 22 in so that these two parts jointly delimit a volume closed which communicates with the tubes 18 of the bundle.
- a heat exchanger comprising a beam formed by a multiplicity of tubes and fins, at the same time as one or two manifolds.
- FIG. 2 shows a perspective view of the respective extensions 26 and 28 of the lateral flanks 22.
- the opening 30, formed in the extension 26 has notches 34, which are three in number the embodiment shown.
- the notches 34 are arranged at 120 ° from each other.
- the end of the tubing 32 which engages in the opening 30 has three pins 36, also arranged at 120 ° from each other. These pins form protrusions projecting outwardly from the tubing.
- the tubing 32 has a flange 40 which limits penetration of the tubing in the opening 30.
- the flange 40 is supported on the wall 26 of the manifold, we turn the tubing in one direction or the other of a certain angle, for example 10 or 20 ° (as shown by the arrow F2 in FIG. 4), so that the pins do not are more opposite the notches 34.
- the tubing is thus kept sufficiently firm on the box collector so that it is possible to carry out the operation soldering without moving.
- lugs 36 are shaped so that a slight tightening tubing on the wall 26 is obtained.
- the tubing 32 instead to be straight cylindrical as shown in the example, has an angled shape. In this case, it should be arranged in a precise angular orientation with respect to to the manifold in order to connect it to a pipe flexible fluid circulation circuit. If the tubing is introduced by a robot, the latter can be adjusted so as to give a suitable angular orientation and no further action is necessary. If the tubing is introduced manually by an operator, the wall 26 preferably include a boss 42 (FIGS. 3 and 4), obtained for example by punching, and forming a stop which limits the rotational movement of the tubing relative to the manifold. When one of the lugs 36 comes into stop against boss 42, suitable angle of rotation is obtained.
- the notches 34 have a low dimension so that it can be filled with the alloy of soldering during the soldering operation.
- FIGs 5 to 8 illustrate a variant of the heat exchanger heat according to the invention, in which means are designed to immobilize the tubing in the final position of its rotational movement, defined by the wall stopper, so as to avoid reversing this movement.
- Figures 7 and 8 for clarity, only a square shaped region of the wall, concentric to the opening is shown.
- the tubing 50 is bent and its end 52 which engages in the manifold here has a single lug 54, associated with a single notch 56 of the opening generally circular 58 through which the tubing passes.
- a stop 60 analogous to the stop 42 of Figures 3 and 4 is formed at the edge of the opening 58, at an angular distance from the notch 56, around the axis A of the opening, slightly greater than 90 ° so as to limit the rotation of the tubing to an angle of 90 ° counterclockwise, as seen from the inside of the manifold, according to arrow F of Figure 8.
- a ramp 62 is juxtaposed with the stop 60, at an angular distance of 90 ° relative to the notch 56.
- the ramp 62 like the stop 60, is produced by deformation, in the direction of axis A, of wall 64 of the manifold, in which the opening 58 is formed.
- tubing 50 has a width greater than the thickness of the wall 64, so that the tubing can rotate freely around axis A after the lug has been engaged through the notch 56.
- the lug After a rotation of an angle close to 90 °, the lug reaches opposite the ramp 62, which presents in opposite it a surface 70 inclined so as to gradually move away from the plane of the external face 72, facing the flange 68, from the wall 64, to a maximum distance very slightly greater than the width of the interval 66 so as to achieve an axial tightening of the wall 64 between the lug 54 and the flange 68, after a 90 ° rotation, while lug 54 comes to rest in the circumferential direction on the stop 60, which projects up to a distance from the wall 72 substantially greater at the width of the interval 66.
- a projection 74 similar to the stop 60 is produced by deformation of the wall 64, in a position slightly offset from notch 56 in the opposite direction of that of the rotational movement of the tubing. This projection cooperates with lug 54 to prevent movement of tubing rotated in the wrong direction when put in place manually.
- clamping means comprising the ramp 62 and the polarizing means comprising the projection 74, although incorporated here in the same embodiment, can be implemented independently of each other. In addition, both can be used in combination with a multiplicity of lugs as described in the first embodiment.
- the heat exchanger of the invention can be used in particular to constitute a radiator for cooling the cabin engine or radiator motor vehicle.
