  • the present invention relates to a device for cooling an electrical or electronic equipment in a turbomachine.
  • a turbomachine comprises a certain number of electrical or electronic equipment, such as actuator control boxes of variable geometries, which generate in operation a large quantity of heat which must be evacuated in order to maintain acceptable temperatures at this equipment. as well as at the level of certain elements of the turbomachine situated in the vicinity of this equipment.
  • Known cooling devices generally comprise means for circulating a cooling fluid such as oil, fuel or air, and are often bulky and complex to implement. In addition, these devices have risks of leakage and must be the subject of regular maintenance operations, which are long and expensive.
  • the invention aims in particular to provide a simple solution effective and economical to these problems.
  • a device for cooling an electrical equipment in a turbomachine comprising at least one Vortex tube comprising an inlet connected to means for supplying pressurized air, and a cold air outlet connected to means for cooling of the electrical equipment, characterized in that the Vortex tube is supplied with pressurized air via a heat exchanger comprising a secondary circuit supplied with cooling fluid by the outlet of the cooling means of the electrical equipment or by the hot air outlet of the Vortex tube.
  • the Vortex tube also called Ranque tube, allows to create by vortex effect a cold air flow and a hot air flow to from a flow of compressed air at intermediate temperature.
  • the inlet air is injected tangentially into a chamber connected to the tube to create a fast swirling flow that goes to one end of the tube, equipped with a conical outlet valve. Part of this air exits the tube through this valve, and the other part of this air is reflected on this valve and then progresses in the tube in the opposite direction by swirling inside the injected air and yielding the heat to that air, then exit through the opposite end of the tube.
  • the cooling device comprises one or more Vortex tubes which are supplied with pressurized air taken by appropriate means on a compressor of the turbomachine or in an annular flow duct of a secondary air stream such that the fan duct of the turbomachine.
  • the cold air outlet of each Vortex tube is connected to a heat exchanger associated with the equipment to be cooled, or to an air injection system of the electrical equipment to be cooled.
  • Vortex tubes are simple to make and use and allow the production of cold air with locally available resources. They are fed with air at a pressure of several bars (typically between 5 and 10 bar) and generate cold air at a temperature that can be about 50 ° C lower than the inlet air temperature. In addition, Vortex tubes are inexpensive, reliable and have a relatively long service life without requiring any particular maintenance, because they do not have moving parts.
  • the cooling device may comprise a heat exchanger of which a primary circuit has an input connected to the outlet of the air sampling means and an outlet connected to the inlet of the Vortex tube, and of which at least one secondary circuit is supplied with fluid. cooling.
  • At least part of the air used to cool the electrical equipment can be injected into a secondary circuit of the exchanger for help cool the air taken from the turbomachine.
  • the air from the hot outlet of the Vortex tube can be injected into a secondary circuit of this exchanger to help cool the air taken when its temperature is lower than that of the air taken from the turbomachine.
  • the heat exchanger may therefore comprise two secondary circuits supplied with cooling air, one by the output of the cooling means of the electrical equipment, the other by the hot air outlet of the Vortex tube.
  • the Vortex tube may be of the double circuit type and then comprises a second input connected to the pressurized air supply means, this arrangement making it possible to double the efficiency.
  • Vortex tubes associated in series or in parallel to cool the electrical or electronic equipment.
  • the invention also relates to a turbomachine, characterized in that it comprises a device for cooling electrical or electronic equipment as described above.
  • the figure 1 very schematically represents a device according to the invention for cooling an electrical or electronic equipment 12 in a turbomachine 10, this device comprising a Vortex tube 14 or Ranque tube fed with pressurized air which is taken from an element 16 of the turbomachine, this element 16 being for example a fan duct, a low-pressure compressor or high pressure, or a smaller auxiliary compressor driven by an accessory housing of the turbomachine.
  • this element 16 being for example a fan duct, a low-pressure compressor or high pressure, or a smaller auxiliary compressor driven by an accessory housing of the turbomachine.
  • the Vortex tube 14 comprises an inlet 18 which opens into a chamber 20 formed between the ends of the tube, the latter having an outlet 22 of hot air at one of its ends and at the other of its ends an outlet 24 cold air.
  • the well-known operation of the Vortex tube will be described in detail in the following with reference to Figures 2 and 3 .

  • the cold air outlet 24 of the Vortex tube is connected to either the exchanger 50 or to an air injection system associated with the electrical equipment 12, this electrical element being for example an electronic control unit for geometries. variables of the turbomachine.
  • the device may also comprise means for filtering the pressurized air which are mounted at 32 or 38 to limit the wear of the Vortex tube and thus increase its service life.
  • the cooling device operates in the following manner: pressurized air is taken from the element 16 and passes into the primary circuit of the heat exchanger 30 to be cooled by heat exchange with a cooling fluid circulating in the secondary circuit 31 and possibly with the air flowing in the secondary circuit 40-44 of the exchanger 30 and with the hot air supplied by the outlet 22 of the Vortex tube.
  • the cooled air leaving the exchanger 30 is injected tangentially into the chamber 20 of the tube which is located near the first end 24 of the tube ( figure 2 ).
  • This chamber 20 has a generally cylindrical shape so as to move the injected air and create a swirling flow 52 fast inside the tube, this flow towards the second end 22 of the tube (arrow 54).
  • the air at the outer periphery of the vortex is relatively hot while the air on the inner periphery of the vortex is relatively cold.
  • a frustoconical control valve 56 is mounted in the second end 22 of the tube and defines with the inner surface of the tube an annular air outlet channel located on the outer periphery of the vortex, that is to say the air hot (arrows 58).
