  • Gear oil reaches in known engines temperatures up to, for example, 155 ° C.
  • engine or transmission fluid in particular oil, which is present in an engine or transmission fluid reservoir of an automobile engine, has a temperature which is significantly below the temperature limit for typical electronic components.
  • About the line section for the engine or transmission fluid such Motor standing. Transmission fluid are guided. Due to the thermal coupling to the housing portion for the electronic components having control means a temperature of the control device is ensured, which keeps the temperature of the control device below its temperature limit. A failure of the control device due to higher temperatures is thereby reliably prevented. Effort for a passive cooling of the control unit can be reduced or avoided altogether.
  • Cooling of the engine or transmission fluid to ensure that this fluid in the delivery section has a sufficiently low temperature can be achieved by appropriate guidance of the fluid over a sufficiently long fluid path in which the fluid has sufficient opportunity to dispense Has heat.
  • a fluid path can be designed in particular spirally.
  • An embodiment according to claim 2 allows a compact Gescousean- order with the line section.
  • a design of the line section according to claim 3 allows a cost-effective design of this and a simple installation.
  • the main body of the line section can simultaneously represent the base plate, which further increases the compactness of the structure of the housing of the control unit.
  • Materials for the main body and / or the lid according to claim 4 have been found to be particularly suitable for guiding engine or transmission fluid with a typical temperature of 120 0 C.
  • the advantages of a cooling arrangement according to claim 5 correspond to those which have already been explained above with reference to the control unit.
  • the engine or transmission fluid pump ensures a safe and special steady flow of engine or transmission fluid through the line section of the housing of the controller.
  • a fluid cooler according to claim 6 ensures a further cooling effect by the engine or transmission fluid, so that it can enter with even lower temperature in the line section of the housing of the control unit.
  • the oil present in the engine compartment or in the transmission can preferably be used according to claim 7.
  • Fig. 1 shows schematically an oil circuit with associated components of a motor vehicle
  • FIG. 2 shows a perspective exploded view of components of a gearbox control unit for use in the engine compartment of the motor vehicle according to FIG. 1;
  • Fig. 3 shows the components of the transmission control unit according to Fig. 2 with the lid mounted.
  • Fig. 1 shows schematically an oil circuit 1 of a motor vehicle.
  • a part of the oil circuit 1 serves as a cooling arrangement for a control unit 2, which is used in an engine compartment of the motor vehicle.

  • the control unit 2 can also be used as an engine control unit.
  • the cooling arrangement has a transmission fluid reservoir in the form of an oil sump 3.
  • a transmission fluid pump 4 is used for pumping transmission fluid 5 through a transmission fluid circuit schematically represented in FIG. 1 by arrows.
  • a transmission fluid supply line 6 shown schematically by an arrow in FIG. 1 is connected to an inlet opening 7 of a line section 8 of a housing 9 of the control device 2.
  • a housing section 10 for a control device of the control device 2 that is to say in particular for control electronics.
  • Housing section 10 is mounted.
  • the line section 8 is partially formed by the base plate 11.
  • the line section 8 can also be placed as a separate part on the base plate 11.
  • the line section 8 is designed in two parts with a base body 12 and a lid 13.

C. occur in the gearbox 18, to which the control unit 2 is also exposed. With the transmission fluid 5 also indicated schematically in FIG. 1 clutch 19 is still supplied.
  • a cooling of the control unit 2 is effected as follows: From the oil sump 3, the transmission fluid 5 is conveyed by means of the transmission fluid pump 4 through the fluid cooler 17 to the clutch 19. A part of the conveyed transmission fluid 5 is pumped via the transmission fluid supply line 6 into the inlet opening 7 of the line section 8. The transmission fluid 5 flows through the line section 8 along the housing section 10 of the housing 9 of the control device 2 and flows out of the channel section 14 through the outlet opening 15. In order to favor the transmission fluid flow between the inlet opening and the outlet opening 15, can in the channel section 14 a fireplace effect can be used. The outflowing transmission fluid 5 returns via the Geretefluid- derivative 16 back into the oil sump 3.
  • the transmission fluid 5 has a maximum temperature of about 120 0 C, which is not exceeded. This, compared to the transmission temperatures cooler oil therefore leads to a cooling of the control device in the housing portion 10 of the controller 2. So it is an active Geretefluidkühlung, in particular an active oil cooling, realized.
