Definitions

  • the invention relates to a liquid-cooled power resistor with at least one resistance filter arranged in the housing, which is arranged directly in a cooling liquid within a closed housing, wherein at least two screens are fastened in the housing, which have bores for pulling through the resistance conductor and thus form brackets for the resistance conductor , and on the use of the liquid-cooled power resistor.
  • Liquid-cooled resistors are known per se.
  • a resistor of the type mentioned is described and shown in US-A-2 640 092.
  • the invention as characterized in the claims, solves the problem of creating a liquid-cooled power resistor which has good heat dissipation and thus a high load capacity and which is structurally simple.
  • the arrangement of the resistance conductor should be low in inductance.
  • the advantages achieved by the invention are essentially to be seen in the fact that the direct arrangement of the resistance conductor in the cooling liquid, preferably in the deionized water, ensures effective and uniform heat dissipation, the heat capacity being relatively high. Because you no longer rigidly the resistance conductor z. B. must attach to a ceramic body, the choice of material is much easier. In the solution according to the invention, large differences in the thermal expansion coefficients of the resistance conductor and its holders cannot cause mechanical damage during the heating. Another advantage is the fact that B. can achieve a low inductance solution by serpentine or meandering arrangement of the resistance conductor.
  • a housing 1 consists of a cylinder 2, which is provided with two flanges 2 ', and an upper cover plate 3 and a lower cover plate 4.
  • the flanges 2' are designed in a square shape, so that their corners make up the cylinder 2 protrude and serve for connection to the cover plates 3, 4 by means of fastening screws 5.
  • the closed housing 1 is provided with two connections 6 for deionized water, an inlet bore 7 being provided in the lower connection 6 and an outlet bore 8 being provided in the upper connection 6.
  • the arrows show the direction of flow.
  • four screens 9 are attached. They alternately leave a flow cross-section 10 on the left and right and serve to deflect the deionized water. They are provided with holes 15, which are shown in Fig. 2.
  • a resistance conductor 11 is guided through these bores 15 in a serpentine manner, so that the diaphragms 9 are simultaneously used as holders for the resistance conductor 11.
  • An upper connecting pin 12 is inserted in the upper cover plate 3 and a lower connecting pin 13 is inserted in the lower cover plate 4. Both pins 12, 13 are fixed with nuts 14 and their outer parts form the electrical connections.
  • the inner part of the upper connection pin 12 is electrically and mechanically connected to the upper end 16 of the resistance conductor 11 and the inner part of the lower connection pin 13 to the lower end 17 of the resistance conductor.
  • the ends 16, 17 of the resistance conductor 11 are pressed into the inner parts of the connection pins 12, 13. You can of course use another known type of connection, for. B. soldering, welding or screwing.
  • the cylinder 2 with the flanges 2 ' is made of aluminum.
  • the cover plates 3, 4 are made of polypropylene.
  • the connection pins 12 and 13 are therefore electrically insulated from one another.
  • the resistance conductor 11 consists of a chromium-nickel alloy, the connecting pins 12, 13 made of copper, the screens 9 made of polypropylene.
  • the deionized water used as coolant runs through the power resistor and is continuously treated in bypass operation.
  • Other cooling liquids known per se can also be used, e.g. B. Oil.
  • other metals, alloys and plastics can also be used for the construction of the power resistor.
  • the cover plates 3, 4 should be made of an electrically insulating material. If the housing 1 is made entirely of metal, the connecting pins 12, 13 must be inserted into the cover plates 3, 4 in an insulating manner.
  • FIG. 2 shows the section 11-11 from FIG. 1.
  • At the top right is the part (17) of the resistance conductor 11 which is connected directly to the lower end 17 of the resistance conductor 11, at the bottom left a section through the upper end 16 of the resistance conductor 11 is shown.
  • the loops of the resistance conductor 11 prevent any mechanical damage during thermal expansion.
  • the holes 15 in the diaphragms 9 are larger than the cross section of the resistance conductor 11. This solution has several advantages.
  • the assembly of the resistance conductor 11 is easier, the resistance conductor 11 can slide during the thermal expansions in the bores 15 and is also well cooled in these places, because small parts of the cooling liquid can flow through these bores 15.
  • FIG. 3 shows the section 111-111 from FIG. 2.
  • the guide of the resistance conductor 11 is shown perpendicular to the guide, as shown in FIG. 1.
  • the resistance conductor 11 is drawn in one plane in FIGS. 1 and 3. The spatial distribution can be seen from FIG. 2.
  • the top cover plate 3 of another exemplary embodiment of the invention is illustrated.
  • This construction corresponds essentially to that according to FIGS. 1 to 3 with the difference that in addition to the upper connecting pin 12 already described, a second upper connecting pin 12 'is inserted in the upper cover plate 3.
  • Both ends of the resistance conductor 11 are connected to these connection pins 12, 12 ′, the center of the resistance conductor 11 being connected to the lower connection pin 13, which has also already been described and is not visible in FIG. 4.
  • two parts of the resistance conductor 11 are present in the housing 1, which can be connected either in series between the connection pins 12 and 12 'or in parallel between the lower connection pin 13 and the short-circuited connection pins 12 and 12'.
  • This variant gives you the option of choosing between two different resistance values.
  • the liquid-cooled power resistor according to the invention is particularly suitable for connecting power thyristors in converter systems.
