Definitions
- the present invention relates to a method for producing a heat transfer liquid circulation tube for heat exchangers.
- the invention finds a particularly advantageous application in the field of heat exchange systems in motor vehicles, including engine cooling radiators.
- Heat exchangers are now known for motor vehicles constituted by a bundle of tubes arranged in parallel on one or more rows, these tubes being intended for the circulation through the exchanger of a coolant, such as water. added with glycol in the case of engine cooling radiators.
- a coolant such as water. added with glycol in the case of engine cooling radiators.
- the water cooling the engine components heats up and must in turn be cooled. It is the role of the radiator to perform this function.
- the water to be cooled is circulated in the tubes of the radiator and is cooled by heat exchange with air, the heat exchange being carried out by means of heat exchange elements arranged in the bundle of tubes.
- the tubes used are made of a low oxidation metal material, such as aluminum or an aluminum alloy.
- a low oxidation metal material such as aluminum or an aluminum alloy.
- heat exchange elements there are different types of heat exchange elements.
- the heat exchange elements are parallel fins traversed by the circulation tubes in holes formed in the fins.
- the maintenance of the assembly is achieved mechanically by crimping by means of a tool inserted inside the tubes so as to deform the walls of the tubes and forcefully apply them against the holes made in the fins.
- Another assembly technology is the brazing of the tubes on heat exchange elements consisting of spacers placed between the tubes.
- these spacers are made in the form of corrugated surfaces, the tubes being soldered on the spacers at the vertices of the corrugations.
- the invention applies both to mechanical assembly exchangers and solder-jointed exchangers, but finds more advantages with mechanical exchangers.
- mechanical type exchanger an exchanger in which the heat exchange elements are, in particular, parallel fins traversed by circulation tubes in holes formed in the fins. It is also possible, in a mechanical type exchanger, that the assembly is mechanically held by crimping by means of a tool inserted inside the tubes so as to deform the walls of the tubes and forcefully apply them against the holes in the fins.
- a mechanical type exchanger may also include flares at some at least the ends of the circulation tubes located inside the manifold of the exchanger.
- flares at some at least the ends of the circulation tubes located inside the manifold of the exchanger.
- a process currently used to manufacture aluminum tubes for the production of heat exchangers is extrusion or coextrusion.
- the final dimension of the tube is obtained directly at the outlet of the extrusion press.
- the two processes differ in taking into account the fight against corrosion.
- For an extruded tube is used as a raw material so-called “long life” (or “long life”) which inherently provides protection against corrosion.
- For a coextruded tube two materials are simultaneously attached to the extrusion press, with one of the materials being used as a corrosion-protective layer.
- the electro-welding is made from a rolled metal sheet. To ensure contact between the two edges of the rolled sheet, it is necessary to apply a forging stress which causes the formation of a weld bead.
- This cord can be scraped outside, with the risk however to create scratches on the surface of the tube which can be the cause of a bad seal at the seal in the water boxes.
- the internal weld bead can only be removed when the diameter of the tube is sufficient. For too small diameters, the introduction of the racer tool is impossible, which poses problems for subsequent assembly operations, in particular for the mechanical expansion of the tube. It is then necessary to change the shape of the crimping tool.
- an object of the invention is to propose a method for producing a heat transfer liquid circulation tube for heat exchangers, which would be less expensive than the extrusion or coextrusion process and which would avoid the disadvantages of the electro-welding process iiés the formation of the weld joint.
- said method comprises the following steps: rolling a tube from a strip of foil comprising, at least, a base metal layer,
- the drawing step of the welded tube reduces the tube dimensions in diameter and thickness while simultaneously removing the inner and outer bead formed during the welding step, which greatly facilitates subsequent operations mechanical assembly.
- the invention has other advantages, such as the possibility of obtaining small sized cladding tubes and managing with a single width of different dimensions of tube.
- the stretching step is followed by an annealing step.
- the tube after stretching being particularly hard, the annealing makes it possible to return the tube to the soft state for the following operations of forming and cutting.
- the invention also relates to a tube for heat exchanger obtained by the method and a heat exchanger comprising at least one such tube.
- Figure 1 shows the different steps of a method according to the invention.
- FIG. 1 illustrates a method for producing a heat transfer liquid circulation tube for heat exchangers, such as those used in the automotive industry, for example.
- a preliminary step (a) consists in choosing the raw material that will be used basic to the realization of the tube.
- This raw material may be a strip of multi-ply laminate with, on the one hand, a base aluminum layer serving as a support and can be a "long-lasting" alloy, and, on the other hand, one or more layers of aluminum plating having properties against corrosion, properties for brazing, ... it is also possible to use a single strip and deposit on the strip 10 before rolling and welding an additional layer of protection against corrosion.
- strapping as raw material offers a flexible solution, allowing an unlimited choice of materials and veneers.
- step (b) the strip 10 of the strip is rolled by placing the protective layer inside or outside if necessary and then welded.
- Welding closes the rolled tube 11 by creating an alloy zone consisting of a mixture of the different layers. This welding operation leads to the formation of an internal and external weld bead more or less important depending on the welding process used: laser, plasma, electro-welding, ...
- Step (c) consists, on the one hand, in stretching the tube 11 thus rolled and welded, then, on the other hand, in annealing the stretched tube 12 at the outlet of the die.
- the drawing operation makes it possible: to reduce the dimensions of the tube in diameter and thickness,
- the annealing is intended to bring the tube 12 to a soft state facilitating the subsequent step (d) of forming the tube 12, round or flat, for example, and cutting to length.
