Definitions
- the invention relates to a cooling device for a spray nozzle suitable for thermal spraying (also referred to below as nozzle for short). Moreover, the invention relates to a spray nozzle assembly with such a cooling device, in which a spray nozzle is installed.
- the cooling device is designed as a shell, wherein the spray nozzle In ⁇ can be arranged in the nenraum.
- the cooling device also has an inlet and an outlet for a cooling fluid, with which the cooling device can be operated.
- This cooling fluid can be liquid (for example water) or gaseous (for example air).
- a cooling device or spray nozzle arrangement of the type specified is known.
- the company offers Sulzer Metco for cold gas spraying under the protected
- Trade name "Kinetics 4000 Cold Spray Gun” means a spray nozzle arrangement in which the spray nozzle is surrounded by a pipe between the spray nozzle and the pipe, an annular gap through which cooling air can be passed, which from an inlet at the convergent part of the nozzle to a The cooling air thereby passes directly over the outside of the spray nozzle, wherein the absorption capacity of the gaseous cooling medium for the heat dissipated from the spray nozzle is comparatively limited.
- the object of the invention is a cooling device for a spray nozzle for thermal spraying or a
- An essential part within the meaning of the invention is understood to be a length fraction of more than two-thirds.
- the length portion should have 90 to 100% of the length of the sheath.
- the length of the casing in relation to the length of the bed also depict ⁇ forming nozzle êtt also a good heat transfer loading. This is the case when the sheath covers a ⁇ we substantial part of the spray nozzle, ie at least two thirds of the length, preferably even 90 to 100% of the length. Since cooling of the material of the spray nozzle according to the invention is effected by a heat transfer into the material of the sheath, it is advantageously possible to use a cooling fluid now for in ⁇ direct cooling of the spray nozzle.
- a cooling line is provided in the casing, which has a closed cross-section and connects the inlet to the outlet.
- a closed Sys tem ⁇ which advantageously can be reliably sealed at the inlet and at the outlet with conventional means. Since the cooling line is closed within the casing, so no wall portions of the cooling line are formed by the surface of the spray nozzle, it can not come to leaks at the transition point between the shell and spray nozzle. Therefore, it is possible to use, for example, liquid cooling fluids without concessions to the process safety, which can provide a much higher cooling performance. It is also possible to USAGE a gaseous fluid ⁇ which is under a higher pressure. This, too, can advantageously increase the cooling capacity.
- the sheath is constructed of two half-shells, wherein a parting line between the half shells in the direction of the longitudinal extent of the sheath extends.
- manufacturing tolerances better compensate for example, by using a filler material in the joining gap las ⁇ sen. It can therefore also choose generous game versions for the design of the mating surface, whereby the manufacturing cost decreases advantageously.
- the diameter of the spray nozzles used can vary as a result of the production, especially if the diameter of the spray nozzles used is variable
- Spray nozzles are made of a hard metal such as tungsten carbide-cobalt, or a ceramic such as silicon carbide. It is particularly advantageous if, in a design of the shell in half shells, each of the half shells has an independent cooling line with its own inlet and its own outlet. This has the advantage that in both half-shells ⁇ a closed system of the cooling pipe may be provided from the inlet to the outlet, without it must come to a transition of the cooling fluid between the one half-shell and the other half shell.
- the interior of the casing has a lining to compensate for thermal expansion differences between spray nozzle and casing.
- the efficiency of cooling can advantageously be increased since a mechanical contact between the material of the spray nozzle and the material of the casing on the Ausklei ⁇ dung can be secured.
- the plantelei ⁇ processing is improved when compared with a variant in which an air gap can arise depending on the thermal expansion of spray and around ⁇ sheathing.
- the thermal expansion coefficient of the lining can advantageously also at least partially prevent the formation of stresses in the bond between the jacket and the spray nozzle so that the spray nozzle expands more than the mating surface widens due to the thermal expansion of the jacket, if the thermal coefficient of the lining is less than that of the sheath.
- the process parameters of the spraying process should be taken into account.
- the spray nozzle experiences a certain extent due to the heating, but in many cases lies below the thermal expansion of the shell, if this is carried out metallic.
- the spray nozzle is heated more than the sheath, from which the heat is also dissipated by means of the cooling fluid. Whether these effects are can be compensated the same or advantageous by choosing a suitable material for the lining depends on the temperatures occurring in the appropriate application.
- the lining may be formed as a separate component, so that it can be inserted into a gap, which forms in the provision of a rough clearance between the casing and the spray nozzle. It is also possible to form the lining as an integral part of the casing. This is then firmly connected to the interior of the casing and itself forms the mating surface for the spray nozzle. In this case, for example, a fit could be chosen which allows little play between the sheath (with integrated lining) and the spray nozzle. It would also be possible to choose a transitional fit that could even be made without playing when the entire tolerance range of the fit is utilized.
- a particular embodiment of the invention is when the liner can also find the function of an adapter for spray nozzles with smaller diameters use.
- a specific casing with a sufficiently large internal diameter can advantageously be manufactured in large numbers, the interior being designed for the nozzle with the largest diameter. If smaller diameter nozzles are used, the excessive gap between the mating face of the shroud and the outer wall of the nozzle in this case will be bridged with a suitable lining.
- the inlet and the outlet are arranged at that end of the casing which lies opposite the mouth of the installed spray nozzle, that is to say it faces away from the latter.
- This has the great advantage that the mouth of the spray nozzle by using the shroud only slightly larger in terms of their required space. he will.
- This is of particular importance when the components to be coated with the spray nozzle itself have a complicated geometry with hard to reach zones. In these cases, the accessibility of difficult to reach regions depends directly on how far the spray nozzle can be brought to the component. This is easier with a mouth of the nozzle smaller diameter. At the same time the sheath can still be brought up to the nozzle mouth to ensure optimum cooling of the same.
- the jacket to demje ⁇ Nigen end located on the side of the mouth of the built-in nozzle is a truncated cone is formed.
- This ⁇ be indicated that the casing decreases in diameter toward the nozzle orifice, wherein the nozzle orifice penetrates the imaginary truncated cone on its lying on the missing tip frustoconical surface.
- This frustoconical surface may be so- ⁇ selects that their surface area is only slightly larger than the outer diameter of the nozzle at the nozzle orifice.
- With the nozzle mouth can be the
- a particularly favorable design for the production is obtained when the sheath is constructed of two nested shells.
- an inner shell is provided, in whose outer circumferential surface the volume of the cooling duct forming channels are introduced. This can be done for example by milling in the surface of the inner shell. It is also conceivable that a cast body is used.
- an outer shell is provided which rests on the outer shell ⁇ surface of the inner shell and the cross section of the Kanä ⁇ le closes to the outside.
- This sleeve can be made, for example, a ⁇ fold by a tubular semi-finished product.
- at a construction of the casing, consisting of two half shells are accordingly longitudinally split pipe shells for the Au ⁇ .chale used.
- gebil ⁇ Deten structure complex guides of the duct forming the cooling duct can be realized cost-effectively, wherein in the management of the channel, a substantial coverage of the shell can be realized with the cooling line.
- the cooling line at least in sections, has a constant cross-section and runs in a meandering manner in the casing.
- the spaces between the meandering parts of the cooling line are constant, so that a gleichmäßi ⁇ ges cooling profile over the circumference of the sheath can be ensured.
- the cooling line has a meandering course, at least the rectilinear sections with a constant cross section can be readily produced.
- the sections that run parallel to the axis of symmetry of the sheath can be formed with a constant cross-section.
- a cooling line with a substantially constant cross-section has the advantage that the cooling fluid is transported at a uniform speed through the cooling ⁇ line and no areas of Stag ⁇ nation of the cooling fluid can form. In such areas of stagnation, the cooling performance of the jacket would otherwise be reduced.
- the object is also achieved with a spray nozzle ⁇ arrangement, wherein in this a spray nozzle is surrounded with a cooling device of the described manner.
- these convergent-divergent Has cross-sectional profile in particular a Kalt moussedü ⁇ se is.
- the heating of cold spray nozzles, in particular in the area of the nozzle throat presents a problem in the use of the cold spraying method, which can be effectively achieved with the sheath according to the invention.
- this is made of a hard metal or a ceramic made. These materials are poorly heat-conductive in comparison to many metallic materials such as copper, so that the heating inside the nozzle can not be dissipated so quickly. However, since these materials are preferably used for reasons of the wear behavior of the nozzles, nozzles which are equipped with a casing according to the invention benefit in particular from the improved cooling device.

- Spray nozzle arrangement with an embodiment of the cooling device according to the invention in longitudinal section and in cross section,
- Figure 3 shows another embodiment of the OF INVENTION ⁇ to the invention the spray nozzle assembly with an embodiment of the invention Cooling device in half-shell design
- Embodiment of the cooling device according to the invention in a longitudinal section, in cross section and in the representation of a development of the sheath to illustrate the course of the cooling line.
- a spray nozzle assembly 11 has a spray nozzle 12 which is surrounded by a sheath 13.
- the spray nozzle 12 is a cold spray nozzle with a convergent section 14 and a divergent section 15, whereby such a nozzle is capable of sufficiently accelerating the particles to be processed so that they, due to their kinetic energy, on the substrate to be coated (not shown) adhere.
- the spray nozzle 12 can be connected by means of a flange 16 to a not shown cold ⁇ injection system.
- Cold spraying is a method known per se, are preferably accelerated at the foreseen for the coating particles by means of the convergent-divergent nozzle 12 to supersonic speed, so that they stick to ⁇ because of their impressed kinetic energy to the surface to be coated.
- the kinetic energy of the particles is used, which leads to a plastic deformation of the same, wherein the coating particles are melted on impact only on their surface. Therefore, this method is referred to as cold gas spraying in comparison to other thermal spraying methods, because it is carried out at comparatively low temperatures at which the coating particles remain substantially fixed.
- a cold gas spraying system is used, the one Gas heating device for heating a gas.
- a stagnation chamber is connected, which is connected on the output side with the convergent-divergent nozzle, preferably a Laval nozzle.
- Convergent divergent nozzles have a converging section (convergent section 14) and a flared section (divergent section 15) connected by a nozzle throat.
- the convergent-divergent nozzle ⁇ he attests output side a powder jet in the form of a gas stream having particles therein at high speed, preferably supersonic speed.
- the sheath 13 according to FIG. 1 is designed in one piece, an interior 17 of the sheath being cylindrical. Since the nozzle 12 is cylindrical on the outside, the casing 13 can be easily pushed over the mouth 18 of the spray nozzle 12. The interior 17 forms with the nozzle 12 a clearance fit, which ensures a displaceability of the order ⁇ coat 13.
- the sheath 13 is made of copper, so that a heat dissipation from the spray nozzle 12 is ensured in the acting as a heat sink sheath 13 due to the good thermal conductivity of copper.
- the heat from the Umman- telung 13 can be effectively dissipated, the Ummante ⁇ lung on a cooling line 19, which can be supplied via an inlet 20 with cooling water as cooling fluid. After the cooling water has flowed through the cooling line 19, this is discharged via an outlet 21 again.
- the cross section of the cooling line 19 can be taken from the cross section of the nozzle arrangement 11 in FIG.
- the sectional plane II-II can be seen in Figure 1.
- the cutting plane of the longitudinal ⁇ section according to Figure 1 is identified in Figure 2 by II.
- a partition wall 22 is provided between the upper part of the cooling line 19 and its lower part in the casing, which, however, does not extend to the top of the casing, thus ends before the drawing level according to FIG 2, so that the cooling fluid within the ring cross section From the upper part of the cooling line 19 can flow into the lower part.
- individual support columns 23 are still provided in their cross section, of which four are located behind the plane of the drawing in FIG.
- a sheath as shown in Figures 1 and 2, could be prepared, for example by means of a selec tive ⁇ laser melting process.
- FIG. 3 another design of the sheath 13 is shown. This has two half shells, the half saddle ⁇ le 24 can be seen in Figure 3, while the other half ⁇ cup is removed from the nozzle 12th For this reason, the nozzle 12 can also be seen in the plan view according to FIG. Moreover, one looks exactly at the impact surface of the half-shell 24, which forms a parting line 25 (see also FIG. 6) after mounting the other half-shell. Evident is also the inlet 20 and the outlet 21 for the cooling fluid.
- the nozzle 12 also allows the convergent section 14 and the divergent section 15 to be viewed from the outside, since this nozzle was manufactured with a constant wall thickness.
- This has the advantage that in the region of the nozzle throat between the convergent gentem and divergent section 14, 15 is no greater wall ⁇ strength of the nozzle is present, that is as 12 remains constant at the nozzle inlet and at the mouth 18, the wall thickness over the length of the spray nozzle. Since the material of the spray nozzle 12th poor thermal conductivity, this can improve the dissipation of heat from the nozzle, as well as in the area of the nozzle throat, the heat dissipation can be done as quickly as at the nozzle inlet and at the nozzle orifice 18
- Spray nozzle has an outer side with a waist 26, the sheath 13 must be constructed of half-shells, which are separated along the extension of the nozzle. Therefore, the jacket does not need to be pushed onto the nozzle, but can be placed in the radial direction of the nozzle.
- the envelope 13 also has two Halbscha ⁇ len 24a, 24b, wherein the parting line perpendicular to the sign ⁇ plane extends (see also Figure 6, where the section VI-VI according to Figures 4 and 5 is shown).
- a lining 28 is provided in a gap, which arises due to the intended clearance between the spray nozzle 12 and the interior 17 of the shell.
- This lining verbes ⁇ sert heat transfer from the injection nozzle 12 into the material of the casing 13.
- the half-shells 24a, 24b are each an independent
- Cooling line 19 is provided. In the sectional plane IV-IV (see Figure 6), the cooling line is cut several times, with the exact course of the cooling line 19 of Figure 5 can be seen.
- FIG. 5 shows a development of the sheath 13. It can be thought of as if the sheath with the cylindrical surface is bent up into a plane. In this plane, then the two joints 25 can be seen as dash-dotted lines.
- the kink in the one parting line 25 according to Figure 5 is characterized zustan- de that at the mouth 18 results in a reduction of the outer diameter of the sheath due to the conical Zu secureds the Ummante ⁇ lung.
- the cooling line 19 has a meandering course.
- the flow direction of the cooling fluid from the inlet 20 to the outlet 21 of the respective half-shell is indicated by arrows.
- the cooling lines according to FIG. 4 represent sections of the portions of the cooling line running in the circumferential direction of the shell. In this way, the axially extending portions of the cooling line 19, which have a constant cross-section, connected to each other. In the region of the conical inlet of the casing 13, in the unwound representation, it appears that the cross section of the cooling pipe 19 is larger. However, this is not the case, how ⁇ Fi can be found gur 4 easily, since the reduction of the
- Diameter must be compensated in the conical region, that the cooling line is wider in the axial direction.
- the cooling line 19 with its sections in cross-section in the casing 13 are all the same. These have a rectangular cross section, which are produced by generating milling grooves in an inner shell 29. Since the grooves of the outside ⁇ fen are radially, it is necessary that the inner shells 30 of the upper half-shell 24a and the lower half shell 24b are sealed respectively by outer shells 30th A connection of the joints can be done by soldering or gluing. However, this fluid connection is required only in the areas of the joints that must be sealed to the outside. The contact surface of the webs located between the grooves 31 to the outer shell 30 need not be materially connected, since a slight leakage between adjacent portions of the conduit 19 can be accepted.
- the structure of inner shell 29 and outer shell 30 can be seen from Figure 4.
