Definitions

  • the subject of the present invention is a large-diameter cylindrical enclosure intended to receive members which have to be cooled by an external fluid such as in particular apparatuses for power electronics of a high speed train.
  • enclosures are used which must be cooled by an external fluid. These enclosures are intended in particular to contain different types of devices or apparatus necessary for the control, or command of industrial installations as well as that of the power cars.
  • these fins must have the largest possible heat exchange surface in order to allow a satisfactory heat exchange efficiency.
  • a first type of fins used is constituted by straight fins.
  • These fins are produced by a metal ribbon which has been previously wound on a suitable machine, a ribbon which is wound on the body of the small diameter tube by exerting significant pressure to ensure their maintenance while forming a seat by knurling each side of the fin.
  • Such methods are limited to very small tubes, the diameter of which can only go up to a few centimeters.
  • the first disc provides a groove on the smooth face of the tube while the second disc guides the metal strip inside the said groove by exerting sufficient pressure on only one side of the fin in order to maintain it.
  • these fins can only be placed on tubes of small diameters.
  • they have the disadvantage of not being sufficiently maintained in the groove so that in certain types of use, this considerably reduces the efficiency of the heat exchange and therefore the calorific efficiency of the device.
  • This poor mechanical strength of the connection can also have the consequence of releasing the smooth surface of the tube so that this smooth surface is then subject to corrosion.
  • a cylindrical enclosure having to be cooled by an external heat transfer fluid, and which has a smooth external surface, at least partially covered with fins regularly distributed over the smooth external surface in a helical arrangement with a fixed pitch, each fin having a body having, in cross section, a substantially L or double L configuration, comprising a foot and a base applied against the smooth external surface, the fins being wound under tension on the smooth external surface by partially overlapping so that their base is at least partially covered by a foot and / or a base of the fin adjacent to the corresponding side.
  • the present invention aims to remedy the drawbacks of the devices currently known by providing a large diameter enclosure whose external surface is smooth which has excellent thermal efficiency, good resistance against corrosion as well as good mechanical resistance of the fins therebetween.
  • a surprising advantage of such enclosures lies in the fact that the fins have a distribution of localized radial undulations, which promotes the flow of the fluid in particular by vortex phenomenon, this flow of the fluid causing an increase in the thermal efficiency.
  • the cylindrical enclosure to be cooled by an external heat transfer fluid which comprises, as known by US-A-3,388,449, a smooth external surface at least partially covered with fins regularly distributed over said smooth outer surface in a helical arrangement with a defined pitch, each fin having a body having, in cross section, a substantially L-shaped configuration, comprising a foot and a base applied against the smooth outer surface, the fins being wound under tension on said surface external smooth by partially overlapping so that their base is partially covered by the foot of the fin adjacent to the corresponding side, is characterized in that it has an axial dimension or height (H) and a diameter (D) such that the H / D ratio is between approximately 1.14 and approximately 5.33, and in that each fin has a knurling which extends over the surface of the part of the base which is covered by the foot of the adjacent fin.
  • H axial dimension or height
  • D diameter
  • each fin has a body having, in cross section, a substantially double L configuration, comprising a first leg and a first base applied against the smooth external surface, the fins being wound under tension on said smooth external surface by partially overlapping so that their first base is at least partially covered by a second leg and a second base of the fin adjacent to the corresponding side
  • the enclosure according to the invention is characterized in that it has an axial dimension or height (H) and a diameter (D) such that the H / D ratio is between approximately 1.14 and approximately 5.33, and in that each fin has, on part of its first base, a first knurling which is covered by the second base of the fin adjacent to the corresponding side, and in that said second base has a second knurling on the surface of its part which covers the knurling presented by the first base covered with the adjacent fin on the other side.
  • one of the aims of this method makes it possible to install fins, at a rate high and continuous, on large diameter cylindrical enclosures whose external surface is smooth without connecting the strip and therefore without causing loss of material, which considerably reduces the cost.
  • Another advantage of this process is that it is particularly well suited for enclosures which have a large diameter and whose surface is smooth.
  • Another advantage is that it allows an adjusted fitting of the fins ensuring that they are kept under tension between them.
  • Another object of this process is that it allows efficient recovery of the heat exchange surface.
  • the present invention relates to a cylindrical enclosure of large diameter intended to receive organs or devices to be cooled by an external fluid as well as a method for producing such enclosures and a device for its implementation.
  • the enclosure 1 is more particularly adapted to receive organs of the power electronics of a high speed train as will emerge from the description which follows.

In a preferred embodiment, it is made of aluminum but it could also be made of any other material or alloys of suitable materials according to requirements such as, for example, stainless steel, copper, copper-nickel alloy, tinned copper, etc.
  • the enclosure 1 has an annular groove 5 intended to receive a seal 6 when it is in the mounted position.
  • This distribution of fins 7 completely covers the heat exchange surface which corresponds to the part of the surface of the enclosure situated between the two ends 3 and 4.
  • These fins 7 are made of a material identical to that of the enclosure 1, that is to say aluminum. However, depending on requirements, these fins could be made of any other type of metal or metal alloy such as in particular copper, copper-nickel alloy, carbon steel or stainless steel, etc.
  • These fins 7 are arranged in a helical winding whose pitch A is determined.
  • the pitch A is determined as being the distance separating two successive fins 7 as it is more particularly illustrated in FIG. 2.
  • the pitch A which is a function of different parameters and in particular the desired thermal efficiency as well as the nature and the shape of the fins 7, is adapted according to the use.
  • the pitch A and the number of fins which are on the enclosure 1 must be determined with precision.
  • the enclosure 1 must comprise 357 fins per meter with a tolerance of more or less 3 fins, that is to say that this enclosure 1 must comprise between 354 and 360 fins per meter.
  • step A Any excessive drop in step A also has the consequence of causing a pressure drop and therefore of reducing the transmission of energy. calorific.
  • each fin 7 may have the consequence of reducing the retention of the fins 7 between them as will be described later, as well as reducing the protection of the smooth external surface 2 of the enclosure 1 against corrosion.
  • Each fin 7, as more particularly illustrated in FIG. 3, has a body 10 which has a L-shaped cross-section.
  • This body 10 has a foot 11 and a base 12 whose dimensions are variable depending on the proper dimension of the fins and desired use.
  • the base 12 has knurling 13 on at least part of its surface to allow tensioning and effective covering of each fin 7 by covering this knurling 13 with the lower part of the foot 11 of the adjacent fin 7.
  • this knurling 13 is arranged on a part of the surface of the base 12 sufficient to ensure its effective recovery by the foot 11 of the adjacent fin on a covering surface corresponding substantially to the knurled surface.
  • This overlap ensures that the fins are held together on the smooth external surface 2 of the enclosure 1 corresponding to the entire surface of the heat exchange.
  • This covering also ensures perfect mechanical strength which allows the enclosure to be used in all conditions.
  • the fins 7 have in cross section a shape of double L as more particularly shown in FIG. 4.
  • each fin 7 has a body 14 which comprises on the one hand a foot 15 and a base 16 covered by a base 17 and a foot 18 of the adjacent fin 7 and, on the other hand, a foot 19 and a base 20 intended to also cover a base and a foot of another fin 7.
  • the base 16 and the base 20 also have a knurling 22 disposed on a part of the surface in order to increase the maintenance under tension of the fins 7 between them.
  • the fins 7 are adapted to have a large heat exchange surface which is maintained over time, as well as perfect mechanical strength of the fins 7 between them on the external surface 2 of the pregnant 1.
  • a surprising and unexpected aspect of the invention resides in the particular conformation of the fins as shown in FIG. 5.
  • the base 24 has over its entire periphery substantially in the vicinity of the base 25 a regular distribution of radial ripples 26.
  • This regular distribution of radial ripples 26 results, as will be described later, of the manufacturing process.
  • corrugations 26 offer an important advantage by allowing improved circulation of the heat transfer fluid, in particular by the effects of turbulence and eddies, which makes it possible to increase the heat exchange efficiency.
  • the subject of the invention is also a method for producing the enclosures 1.
  • the tension exerted, during the fitting of the fins 7, is sufficient so that they are held in a coherent manner with one another and that they cannot shift relative to each other which whatever the conditions of use.
  • enclosure 1 with a large diameter whose external surface 2 is smooth over at least part of their total external surface corresponding to the heat exchange surface.
  • a metal strip 30 is continuously unrolled at a determined speed.
  • the critical tension must in this case be reached in order to ensure an effective and homogeneous retention of the fins 7 as well as a precise adjustment of their position on the smooth external surface 2 of the enclosure 1.
  • the fins 7 are not sufficiently held together on the external surface 2 of the enclosure 1 so that they can separate during use. This separation is particularly frequent when these enclosures are subjected to significant mechanical or thermal stresses. This separation has the consequence of freeing an area from the surface 2 of the enclosure 1, which is therefore subject to corrosion. It follows that this corrosion can cause the formation of micro-cracks and therefore break the seal of the enclosure 1 which can lead to the stop of the operation of the high speed train.

  • the speed of rotation of the enclosure 1 is determined in order to ensure a desired distribution according to a determined pitch of the fins 7.

  • This device also includes means 41 for storing the metallic strip 30 in the form of a reel.
  • These means 41 consist of a horizontal magazine 42, the dimensions of which may be adjustable as a function of those of the coil of metal tape 30. Of course, one could envisage the presence of several magazines of different sizes possibly superimposed or arranged side by side.
  • Means 43 are provided for exerting traction on the metal strip 30 which runs continuously. These means 43 consist of a wheel 45 driven in rotation around a shaft actuated by motor members of a conventional type.
