Definitions

  • Cooling device for a motor vehicle with a cooling channel for a cooling medium
  • the invention relates to a cooling device for a motor vehicle with a cooling channel for a cooling medium.
  • Cooling devices for motor vehicles are known. As a rule, this is a water cooler, in which the water is conducted through a sewer system, which is achieved by liquid pumps. Such cooling devices are generally used to cool the engine.
  • the object of the invention is to create a cooling device for a motor vehicle which, in addition to the function of cooling the motor, also fulfills another.
  • the object on which the invention is based is achieved by a cooling device in which electronic components are arranged on the outside of the cooling channel.
  • Capacitors, processors or transistors can be used as electronic components. They are usually used to electronically control or regulate processes in the motor vehicle.
  • the outside of the cooling channel is understood to mean the outside of the volute casing or the hoses or the valves which are built into the cooling circuit.
  • the electronic components can be arranged on the outside of the cooling duct by clamping or screwing, for example.
  • the cooling device for a motor vehicle can also cool electronic components in such a way that the high temperatures to which they are normally directly exposed cannot cause any disadvantageous damage. This makes it possible to use electronic components that are more temperature-sensitive and therefore cheaper.
  • the cooling effect takes place through the arrangement of the electronic components in the vicinity of the cooling medium, water generally serving as the cooling medium.
  • a preferred embodiment of the invention consists in that electronic components for controlling or regulating the pump for transporting the cooling medium are arranged on the outside of the cooling channel. Since the pump for transporting the cooling medium is also arranged directly on the cooling channel for the cooling medium and must also be controlled by electronic components, it is particularly advantageous to arrange these electronic components both in the immediate vicinity of the pump and on the outside of the cooling channel, so that advantageous cooling of the electronic components can take place.
  • the electronic components are connected to the cooling duct via an angle element. Only that is between the electronic components and the cooling duct
  • Angle element which is usually made of metal and can dissipate the heat in a particularly advantageous manner via the cooling channel to the cooling medium. It is advantageous that the electronic components can be cooled by the cooling medium, even if there is no installation space available for a direct arrangement of the electronic components on the outside of the cooling channel. In addition, the electronic components can be attached to the angle element relatively easily.
  • the electronic components are fastened with an adhesive connection. It is advantageous that additional fastening means, such as screws or rivets, can be dispensed with entirely.
  • additional fastening means such as screws or rivets
  • Fig. 1 shows the cooling device for a motor vehicle in cross section with the pump for transporting the cooling medium.
  • Fig. 2 shows the cooling device for a motor vehicle in cross section with the angle element.
  • FIG. 1 the cooling device for a motor vehicle with a cooling channel 3 for a cooling medium is shown in cross section.
  • Electronic components 1 are arranged on the outside of the cooling channel.
  • a pump 5 with an impeller 4, which projects directly into the cooling channel 3, is used to transport the cooling medium.
  • Components 1 are arranged directly on the outside 2 of the cooling duct 3.
  • the attachment can be done in a particularly advantageous manner by gluing.
  • the 2 shows the cooling device for a motor vehicle in cross section with an angle element 6.
  • the electronic components 1 are connected to the cooling duct 3 via the angle element 6.
  • the angle element 6 is usually made of metal and conducts the heat from the electronic components 1 via the outside 2 of the cooling channel 3 into the cooling medium.
