Definitions

  • the invention relates to an arrangement with at least one electrical winding according to the preamble of claim 1.
  • Arrangements having at least one electrical winding are known. These include, in particular, transformers and chokes, the windings of which are carried by or enclose a ferromagnetic core. In the operation of these arrangements, losses occur in the form of heat in the windings. Additional heat losses occur as a result of magnetization reversals in the cores; these increase with higher frequency. With chokes connected on the output side of the converter, particularly high heat losses occur due to the required high clock frequencies.
  • a converter in which a plate and a plurality of heat pipes are provided for heat dissipation.
  • the heat pipes bear with their lateral peripheral surface on the plate 50, which acts as a heat collector, the large side surface is in thermal contact with the laterally adjacent heat pipes.
  • the winding and the core are completely surrounded by a dielectric resin. Accordingly, the heat dissipation via this insulating layer takes place.
  • the cooling has pipelines through which a cooling fluid circulates.
  • the cooling tubes open into a base cooling plate, which is traversed by the cooling liquid.
  • the object of the invention is to dissipate the heat loss more effectively and thereby enable in particular smaller arrangements.
  • the means further comprise an absorber block, which is connected to the dissipation of heat with the heat pipe (heat pipe), the end of which opens into the absorber block.
  • heat pipe heat pipe
  • the heat-absorbing elements in the region of the winding and / or, if the winding is supported by a ferromagnetic core are arranged in the region of the core.
  • cooling plates are also referred to as cold plates. Since the cooling plates can be operated in combination with a heat pipe with normal industrial water, eliminates the known problems regarding pressure drop to be maintained, available or required flow rates, water quality, etc.
  • the solution with the cooling plate can be relatively freely dimensioned if sufficient cooling capacity is available. With appropriate local conditions, of course, an air flow can be used for cooling the cooling plate, but with the disadvantage that then a more targeted heat conduction is no longer possible.
  • FIG. 1 shows an arrangement with a throttle 1, which has an electrical winding 2 on a ferromagnetic core 2a, wherein the core 2a is enclosed by the winding.
  • the winding 2 here belongs to an electrical throttle 1, but may also be the winding of a transformer and the like.
  • a heat-absorbing element 3 is arranged in the form of an absorber block 3a.
  • the absorber block 3a is connected to an end 4a of a heat pipe 4, the end of which (in the longitudinal direction of the heat pipe 4) extends into the absorber block 3a or opens into the absorber block 3a, i. thermally conductively connected to the absorber block 3a.
  • the other end 4b of the heat pipe 4 is connected to a cooling plate 5 (so-called cold plate), which is flowed through for cooling by a liquid, not shown.
  • FIG. 2 is one opposite FIG. 1 alternative embodiment shown.
  • the heat-absorbing element 3 which is also formed here as an absorber block, within the core 2a and together with this within the winding second
  • the heat absorbing member 3 formed as the absorber block 3a is seen without the coil 2 and the core 2a connected to the heat pipe 4 and thermally connected to the cooling plate 5.
  • the current flowing through the electrical winding 2 of the reactor 1 generates a magnetic field.
  • the heat loss is caused by the current flow in the winding 2 and by the permanent Ummagnetmaschineen in the core 2a.
  • the plate 5 is cooled by means of liquid so that between the two ends 4a, 4b of the heat pipe 4, a sufficient temperature difference is present. This causes the heat to be transported by the heat pipe 4 from the heat absorbing member 3a to the plate 5, respectively.
  • the element 3a cools down accordingly until the absorbed amount of heat is equal to the amount of heat dissipated by the heat pipe 4.
  • FIG. 1 The heat generated in the winding 2 is absorbed by the one (upper) side and the core 2a from the other (lower) side of the element 3 and dissipated via the heat pipe 4.
  • the heat removal is preferably only from the core 2a.
  • the cooling plate 5 in each case provides the required low temperature level, which is required for the heat dissipation by means of heat pipe 4.
  • heat pipe 4 in conjunction with heat-absorbing elements 3 in the form of absorber blocks 3a can be used selectively at critical points. This is required, for example, in the case of output chokes with a high proportion of core losses directly in the center of the core 2a (of the core package), for high-current coils directly in the area between the individual windings or winding layers, but also in the area between winding 2 and core 2a.
