Definitions

  • the present invention relates to a cooling element, the structure of which ensures that a contact area between the cooling element and an object to be cooled is sufficiently large.
  • the contact surface between the object to be cooled and a cooling element plays an important role.
  • the contact surface should be as large as possible so that the generated heat could be transferred as efficiently as possible from the object to be cooled to the cooling element.
  • a gap is formed between the cooling element and the object to be cooled in a region intended to be the contact surface.
  • Such a gap is also formed, for instance, when a coil is wound around a cooling element with a rectangular cross-section, because due to the angularity of the cooling element the coil cannot follow the shape of the cooling element closely along its whole length. Because of the above-mentioned gap, the contact area becomes smaller and the cooling power decreases.
  • a cooling element is utilized, the frame part of which comprises a curved surface and a bending point, by which the curvature of the curved surface may be changed.
  • the shape of the cooling element may thus be arranged to correspond to the surface shape of the object to be cooled, which makes the cooling area as large as possible.
  • the radius of curvature of the curved surface need not be the same along the entire region of the curved surface, but it is possible that the radius of curvature varies depending on the shape of the object to be cooled and that the curved surface even has planar sections that separate the curved sections.
  • FIGS. 1 and 2 illustrate a first preferred embodiment of a cooling element of the invention
  • FIG. 3 illustrates a second preferred embodiment of the cooling element of the invention
  • FIG. 4 illustrates a third preferred embodiment of the cooling element of the invention.
  • FIGS. 1 and 2 illustrate a first preferred embodiment of a cooling element 1 of the invention.
  • FIG. 1 shows the cooling element from an end
  • FIG. 2 shows the side of the cooling element 1 that is facing downwards in FIG. 1 .
  • the frame part of the cooling element 1 is provided with at least one cooling channel 2 , through which a cooling medium, such as air or a liquid, may be supplied.
  • a cooling medium such as air or a liquid
  • suitable connectors are attached to the cooling channel 2 .
  • the frame part of the cooling element 1 is provided with a first curved surface 3 , which in FIG. 1 is a convex surface.
  • the frame part is provided with a bending point 5 (in FIGS. 1 and 2 there are two bending points), at which the frame part may be bent such that the curvature of the first curved surface 3 changes.
  • the bending points 5 are provided with grooves, which extend along the entire length L of the frame part and at which the thickness d of the frame part is smaller than the thickness D of the frame part in other parts.
  • a second surface 6 of the frame part, facing downwards in FIG. 1 is also curved.
  • this is not necessary in all embodiments, but the shape of the second surface may vary depending on the application.
  • the cooling element of FIGS. 1 and 2 may be manufactured from aluminum by extrusion, for instance.
  • the frame part may be directly provided with cooling channels 2 and grooves 5 at the extrusion stage, and the surfaces 3 and 6 may be directly provided with a desired shape.
  • the bending points 5 are preferably shaped so flexible, i.e. in FIGS. 1 and 2 their material thickness is so small, that the cooling element automatically adapts to the shape of the object to be cooled, when the cooling element and the object to be cooled are pressed against each other.
  • FIG. 3 illustrates a second preferred embodiment of the cooling element 1 ′ of the invention.
  • FIG. 3 shows the cooling element from an end, whereby its cooling channels 2 ′ can be seen.
  • the cooling element of FIG. 3 is a cooling element of a coil, such as a choke coil.
  • the cooling element 1 ′ may be manufactured similarly as described in connection with FIG. 1 .
  • the first surface 3 ′ is convex.
  • a coil 7 which is wound around at least the cooling element 1 ′, is pressed against the convex first surface 3 ′. Because of the groove at the bending point 5 ′, the frame part of the cooling element 1 ′ at the bending point is sufficiently flexible to make the force applied by the coil 7 to the cooling element 1 ′ change the shape of the first curved surface 3 ′ so that it closely follows the shape of the coil 7 . As large a cooling area as possible is thereby created between the coil 7 and the first curved surface 3 ′, through which the generated heat can be transferred from the coil 7 to the cooling element 1 ′.
  • FIG. 3 shows that the second curved surface 6 ′ of the cooling element 1 ′ is also in contact with the coil. More specifically, the cooling element is located between different layers 7 and 8 of the coil, whereby the first convex surface 3 ′ cools down the coil layer 7 and the second concave surface 6 ′ cools down the coil layer 8 .
  • FIG. 3 also comprises a second cooling element 9 , the curved upper surface of which is in contact with the coil layer 8 and the smooth lower surface of which is in contact with an iron core 10 of the coil.
  • a second cooling element 9 may provide a very efficient cooling for the coil and its iron core.
  • FIG. 3 does not show the lower half of the coil and the iron core, which may comprise a second cooling element 1 ′ and a cooling element 9 arranged similarly as in the shown, upper half.
  • FIG. 4 illustrates a third preferred embodiment of the cooling element of the invention.
  • FIG. 4 shows two cooling elements 1 ′′ arranged around a cylindrical object 4 ′′ to be cooled.
  • This object to be cooled may be, for instance, a capacitor 4 ′′, against the outer surface of which the cooling elements 1 ′′ are pressed by means of a clamping band 11 .
  • the grooves at the bending points 5 ′′ of the frame parts of the cooling elements make the frame parts bend in such a manner that their first concave surfaces 3 ′′ follow the shape of the outer surface of the object 4 ′′ closely.
  • Due to the fastening means of the cooling elements 1 ′′, the second surfaces 6 ′′ thereof are also curved, in this case convex, but if the fastening means differs from the example, these second surfaces need not necessarily be curved.
