Definitions
- the present invention relates to a method of manufacturing a tank intended to be integrated in a heat exchanger.
- heat exchangers such as air conditioners use a tank that is connected to the collector pipe, itself connected to the cooling fins.
- the prior manufacture of the tank as it is currently done essentially consists in extruding a piece in the form of a tubular piece and in bringing back to one of the open ends a piece forming a washer which is subsequently fixed by brazing with fluxing.
- the patent FR 2 785 043 discloses a manifold (14) in at least two parts with one forming a tube and the other forming a threaded end (19) in which is screwed the filter cartridge of the reservoir, the welded circular tube extended at one of its ends by a tube section (19) made in an extruded section pressed around the tube portion and closed at the other end by a brazed lid (26).
- a collector requires a lot of expensive operations since it is necessary to realize on the one hand tapping respectively in the sheath and the coaxial tube, on the other hand the development of a longitudinal groove on the collector tube, the arrangement of a plastic deformation zone and finally an arc or laser welding operation.
- the present invention aims to solve the aforementioned drawbacks using simple means, easy to implement and inexpensive.
- the invention relates to a method of manufacturing a reservoir intended to be integrated in a heat exchanger of the type consisting in a step of rolling a sheet of metal on itself and then welding the rolled edges together in order to constitute a tube and in a subsequent step to place, at one end of the tube, a plug and at the other end a nozzle for housing a filter and finally to fix and seal by soldering the plug and the tip to the tube, characterized in that beforehand, it carries out a plating of the face of the tube constituting the inner wall of a solder metal, in that the step of placing the stopper and a ring is carried out, intended to house the tip internally, by fitting inside the tube, the fixing and sealing step of the plug and the ring being performed by brazing the plated metal on the inner wall of the tube while that of the tip is performed by fitting into the ring with interposition of a seal between them and then fixing the tip to the tube.
- plating is understood here and in the context of the invention a deposit operation of a metal coating for providing the subsequent solder metal, such as aluminum.
- Figure 1 is a cross-sectional view of a tank according to the state of the art
- Figure 2 is a cross-sectional view of a tank according to the invention.
- Tanks according to the state of the art and according to the invention (1) are intended to be integrated in a heat exchanger not shown in full.
- the tank (1) shown in FIG. 1 comprises, according to the state of the art, a tube (10) made in one piece by extrusion, one end of which (11) forms the end of a filter and which has the inside a flange (12) forming a locking washer for the male end portion of the not shown filter.
- a plug wall (2) At the other end of the tube (13) is attached by fluxing a plug wall (2).
- Brazing with fluxing is a welding which is carried out in a manner known per se by heating the assembled assembly (10,2) to melt the aluminum layer which covers only the plug (2) and thus obtain a perfectly sealed connection between these two pieces (10,2).
- a method of manufacturing a tank (1) intended to be integrated in a heat exchanger (1) of the type consisting of a step to roll a sheet of metal on itself and then weld together the rolled edges to form a tube (10) and in a subsequent step to place, at one end (13) of the tube, a plug (2) and to the other end (11) a nozzle (3) for housing a filter and finally to fix and seal by sealing the plug (2) and the tip (3) to the tube (10).
- a plating of the face of the tube (10) constituting the inner wall (100) of a brazing metal is carried out, in that the cork placement step is carried out ( 2) and a ring (4), intended to house the end piece (3), by fitting inside the tube (10), the step of fixing and sealing the plug (2) and the ring (4) being made by brazing the plated metal on the inner wall (100) of the tube (10) while that of the tip (3) is formed by fitting into the ring with interposition of a seal (5) between them then attaching the tip to the tube (10).
- the plating of the face (100) of the tube (10) is carried out before rolling.
- the tip (3) inside the tube (10) before the fitting of the tip (3) inside the tube (10), it comprises an intermediate step of fitting inside the tube of a washer (12). ) intended to serve as a stop for the filter itself intended to be housed in the nozzle, the sealing of the washer (12) with the tube (10) being made by brazing the plated metal on the inner wall (100) of the tube.
- the inner wall (100) of the latter is deformed towards the inside of the tube (10) so as to constitute a longitudinal positioning stop of the puck.
- the step of brazing the metal plated internally in the tube (10) during the soldering step with global fluxing of the heat exchanger is performed.
- a plating of the face of the tube (10) constituting the outer wall (101) of a brazing metal is carried out beforehand, the brazing of the latter allowing the fixing and the sealing between the tube and the fastening elements of the heat exchanger.
- the step of soldering the externally plated metal (101) to the tube (10) during the step with global fluxing of the heat exchanger is carried out.
- the attachment of the tip (3) fitted into the ring to the tube (10) is formed by interlocking pins (30) elastically deformable, formed at the periphery of the tip (3), in slots (102) formed at the end of the tube (10).
