Definitions

  • Vehicle Propulsion System bearing attorney docket No. 58,335, and filed-on the same date herewith;
  • the present invention relates to a housing for electronic components of an electric vehicle. More particularly, the present invention relates to an electric vehicle propulsion system cooling assembly. While the invention is subject to a wide range of applications, it is especially suited for use in electric vehicles that utilize batteries or a combination of batteries and other sources, e.g., a heat engine coupled to an alternator, as a source of power, and will be particularly described in that connection.
  • batteries or a combination of batteries and other sources e.g., a heat engine coupled to an alternator, as a source of power, and will be particularly described in that connection.
  • Conventional electric vehicles include a motor, a battery, and electronic components for charging the battery and operating the motor.
  • electric vehicles have been designed to be generally lighter than gasoline-powered vehicles, the weight of a typical electric vehicle is such that a substantial amount of power must be utilized in the motor to propel the vehicle. Because of friction within the motor, and because of resistance to electric current flow through various parts of the motor, heat is generated in the motor during use. If this heat is not removed, the potential for failure of the motor components exists.
  • a cooling system to cool the motor. Such a cooling system included a pump which circulated cooling fluid through the motor and a radiator.
  • a first fluid such as ethylene glycol
  • a second fluid such as motor oil
  • the electrical components of conventional electrical vehicles can experience an undesirable build-up of heat due to the large electric currents used.
  • the motor controller within an electric vehicle system control unit may include a number of electronic switches such as insulated gate bipolar transistors (IGBT's).
  • IGBT's insulated gate bipolar transistors
  • the IGBT's rapidly switch on and off to provide AC current flow to the motor, generating a substantial amount of heat.
  • EMI electromagnetic interference
  • electrical components of the vehicle propulsion system Another difficulty with conventional electric vehicles is electromagnetic interference (EMI) generated by electrical components of the vehicle propulsion system. While it may be desirable to mount many of the electrical components together for ease of manufacturing and servicing, doing so can increase the intensity of generated EMI, and may even cause the electrical components to interfere with each other. For example, the IGBT's cause a substantial amount of EMI during operation, which, if not attenuated, can cause unacceptable interference with other electrical components, both on and off the vehicle.
  • Conventional electric vehicles have therefore utilized complicated shielding elements to prevent EMI disruption of closely spaced electrical components. These shields proved expensive and were complicated to manufacture.
  • electrical components have been spread out within an electric vehicle to reduce the intensity of generated EMI and make it less likely that EMI generated by one electrical component will disrupt other electrical components. However, spreading out various electrical components requires more wiring to connect the components, more housings to hold the components, and more labor to manufacture and service the components, than does mounting the components together.
  • a cold plate of such a housing may comprise a base member and a cap member, both made of metal plates, which are preferably brazed together.
  • An inlet and an outlet are provided in the base member for admitting and emitting fluid to and from a machined groove.
  • Corrugated aluminum lanced offset finstock is brazed between the base member and cap member to improve thermal conduction of heat to the fluid in the groove. Ridges are disposed in the groove to secure the base member and cap member together. While performing its intended function well, the above cold plate is expensive to manufacture.
  • the machining of the groove and the brazing together of the base member and the cap member are expensive, thus making the cost of manufacture of the cold plate high. Therefore, a cold plate having similar performance capabilities as the above cold plate, but which is less expensive and complicated to manufacture, is desired.
  • the present invention is directed to an electric vehicle system control unit housing that substantially obviates one or more of the above problems
  • an electric vehicle propulsion system cooling assembly for channeling cooling fluid.

  • outlet means is provided for emitting the fluid from the opening.
  • the cap member channels the fluid sequentially through the inlet means, the opening, and the outlet means.
  • At least one of the base member and the cap member is formed of the thermally conductive material to permit transfer of thermal energy to the fluid while the fluid is in the opening.
  • an electric vehicle propulsion system cooling assembly for channeling cooling fluid.

As shown in Figs. 2-4, when the cap member 74 is secured to the base member 72, the top surface 76 of the base member covers the opening 88, thereby creating a passage for fluid flow through the base member and cap member.

  • the base member 72 and the cap member 74 may be bonded together. If the base member 72 and cap member 74 are bonded together, a film adhesive 86, as shown in Fig. 4, may be employed to secure them together. Attaching the base member 72 and cap member 74 together with screws or a film adhesive is less expensive than brazing them together, and thus provides an easy to assemble and inexpensive heat sink.
