Definitions
- the invention relates to heat exchangers of the type comprising a fluid box communicating with a multiplicity of parallel and mutually aligned fluid circulation tubes, the fluid box comprising a tubular wall extending in the direction of alignment of the tubes and having a multiplicity of openings through which they pass.
- this interior surface being generally circular
- the ends of the tubes abut at the center of the circular profile if their width in the radial direction is equal to its diameter, and beyond the center if this width is less than the diameter , the further away from the center the smaller the width of the tubes.
- the space available in the fluid box facing the ends of the tubes may then become insufficient for proper circulation of the fluid between the tubes and the fluid box. In addition, this space can vary from one tube to another due to manufacturing dispersions.
- the object of the invention is to remedy these drawbacks.
- each tube in a method of the kind defined in the introduction, abuts on at least one internal projection carried by the tubular wall.
- the end of the tube comes into contact with the projection through at least one of its two regions furthest from the median plane of the alignment of the tubes.
- the tubular wall has a multiplicity of internal projections aligned in its longitudinal direction and arranged in line with the tubes respectively.
- the tubular wall has an internal projection extending continuously in its longitudinal direction, facing the set of tubes.
- each tube can abut on two internal projections located respectively on either side of the median plane of the alignment of the tubes.
- the subject of the invention is also a tubular wall for implementing the method defined above, having a multiplicity of openings aligned in its longitudinal direction for the passage of the tubes and a corresponding multiplicity of internal projections carried by the wall, each projection being arranged in line with the corresponding opening in the longitudinal direction of the tubular wall and offset with respect thereto in its circumferential direction, and the projections being mutually aligned in the longitudinal direction.
- the tubular wall has an inner projection carried by the wall, extending continuously in the longitudinal direction of the tubular wall and offset from the openings in its circumferential direction.
- the internal projection is formed by a depression of the wall.
- the left half of the figure shows, in cross section, a tubular wall 1 with a circular profile belonging to a fluid box of an air conditioning condenser of a motor vehicle, having an opening 2 as well as other openings aligned with it in the longitudinal direction of the wall 1.
- the opening 2 is traversed by a fluid circulation tube 3, the longitudinal direction of which is perpendicular to that of the wall 1 and having an elongated cross section transversely to the latter direction.
- Other similar tubes aligned with the tube 3 pass through the other openings.
- the end 4 of the tube 3 has been inserted into the fluid box through the opening 2, along the arrow F parallel to the longitudinal direction of the tube, until it abuts against the internal surface 5 of circular profile of the tubular wall, by its two marginal regions 6 furthest from the median plane P of the row of tubes, these two regions 6 being symmetrical to each other with respect to the plane P.
- the latter contains the longitudinal axes of the wall 1 and tube 3.
- the right half of the figure shows a tubular wall 11 having the same circular base profile as the wall 1, however locally modified by a depression defining a projection 18 inside the tubular wall, this depression being offset in the circumferential direction relative to openings 2 identical to those of wall 1, and extending continuously, in the longitudinal direction of the tubular wall, facing all of these openings.
- a circulation tube 3 identical to that shown in the left half, whose penetration inside the tubular wall is limited by the arrival of the marginal region 6 of its end 4 in abutment against the projection 18.
- the free space 19 remaining inside the fluid box facing the end 4 of the tube 3 is larger than the corresponding space 9 in the known heat exchanger.
- this space 19 is not affected by the dimensional variations concerning the width of the tube 3, since the projection 18 extends sufficiently far towards the plane P to always come into contact with the end of the tube.
- the continuous recess 17 can be replaced by a multiplicity of recesses mutually aligned in the longitudinal direction of the tubular wall, each of the corresponding projections coming into contact with the end of one of the tubes.
- two projections or two series of projections can be provided on either side of the plane P, for example symmetrically with respect thereto, to come into contact with the two marginal regions 6 respectively of the ends of the tubes .
- the projection 18 can be produced by any other means than a depression and in particular, when the fluid box is extruded, this projection can be made during the extrusion operation of this box.
- the tubular wall 11 can be formed in a single piece of sheet metal, for example a substantially rectangular sheet rolled and brazed edge to edge. It can also be formed from two parts assembled in a sealed manner and each extending over a fraction of the circumference, the projection (s) 18 being formed on at least one of these two parts.
