Definitions

  • the invention relates to a pump for conveying a liquid, especially coolant for the internal combustion engine of a motor vehicle in which the delivery rate controlled depending on engine operating parameters or to convey a cleaning liquid for Headlights or windows, especially one Motor vehicle, being used to regulate the funded Liquid quantity a temperature sensor is provided.
  • the invention is based on the problem of a pump type mentioned in the beginning so that for different Applications and installation conditions
  • the amount of coolant can be regulated as precisely as possible.
  • the pump for using the pump as a coolant pump for the internal combustion engine of a motor vehicle is special advantageous if according to a development of the invention the pump as a drive depending on Signals of the temperature sensor with regard to its speed controlled electric motor.
  • This allows you to Regulation of the delivery volume, the temperature of the coolant immediately take into account without it Falsified measurements due to a greater distance of the temperature sensor can come from the pump. thanks to the Invention can optimally deliver the respective volume Cooling requirements can be adjusted.
  • coolant pumps which via V-belts directly from the internal combustion engine are driven is the energy requirement of the pump, because they always use the one you need Funding capacity can work.
  • the invention of the temperature sensor on the outside with a Pump housing of the pump is connected.
  • the arrangement of the Temperature sensor on the pump housing allows at the same time a reliable recording of the to be determined Temperature through the wall of the pump housing and easy replacement of the temperature sensor in the Accident.
  • a direct contact to the pumping liquid excluded with the temperature sensor so that the pump designed in this way is also problem-free used for aggressive liquids can be.
  • Another particularly recommendable embodiment of the Pump according to the invention is given when the pump housing a reduced one in the area of the temperature sensor Has wall thickness. This is the heat transfer the heat given off by the liquid the wall of the pump housing significantly improved, so that on the one hand the accuracy of the measured values recorded in this way significantly increased, but on the other hand also the response behavior with strong temperature fluctuations, in particular during commissioning, can be improved.
  • the improved heat transfer can also be through an appropriate selection of a suitable material increase.
  • the pump housing can be provided with an outside Flattening or with one on an inner wall arranged formation to be provided to the desired position of the temperature sensor a reduced To achieve wall thickness.
  • a modification of the pump according to the invention in which the temperature sensor in a recess of the pump housing is inserted.
  • the temperature sensor is therefore only by a comparatively small remaining Material thickness of the wall of the pump housing from the Liquid separated, so that heat loss - in particular by discharge over the surface of the pump housing - can be significantly restricted.
  • the recess is effective against damage
  • Protected arrangement of the temperature sensor, in particular mechanical damage from neighboring components can be largely excluded.
  • the temperature sensor arranged in the area of a pump chamber of the pump is. This can change the temperature of the liquid transferred quickly and without additional heat loss become.
  • the temperature sensor is for this example fixed on the outside to a wall of the pump chamber or inserted into a recess that has an immediate Contact between the liquid and the temperature sensor enables.
  • Another particularly recommendable embodiment of the Invention is given when the temperature sensor in Area of a connecting flange of the pump arranged is.
  • the measured values for determining the temperature the liquid immediately before the entry of the Liquid captured in the pump chamber This will possible measurement deviations, in particular caused by external heat transfer from the pump drive to the Liquid, avoided.
  • the measured values therefore have a accordingly increased accuracy.
  • this beneficial effect can be increased by the temperature sensor in the area of an inlet opening the pump chamber is arranged. This will additionally to the reaction through the pumping process and the energy released in the process on the measured value acquisition also such deviations caused by a possible Heat dissipation in the connection area of a line element can arise avoided.
  • the temperature sensor, its essential components from electrical Components can exist in the control of the pump be integrated appropriately. An additional one is therefore omitted Effort for contacting the temperature sensor, at the same time achieving increased operational reliability becomes.
  • the temperature sensor can, for example also on a circuit board common to the control the pump can be arranged, whereby the Manufacturing costs can be further reduced.
  • the temperature sensor with one made of a ceramic material Carrier element is connected.
  • the fixation of the temperature sensor can be equally reliable and without the risk of damaging neighboring and thus electrical components exposed to heat respectively.
  • the insensitivity of the ceramic material mechanical temperatures also prevent high temperatures Damage to the carrier and thus the connection between the temperature sensor and the pump.
  • a further development of the invention is also particularly useful, for improved heat transfer between the temperature sensor and the pump housing a thermal compound is provided.
  • This makes an essential improved heat transfer to the temperature sensor ensured, by the immediate contact area between the temperature sensor and the pump housing an additional contact surface by means of the thermal compound is added. Therefore, at the same time, loosening the temperature sensor from the direct contact area on the Pump housing avoided due to vehicle vibrations, so that operational safety is significantly increased can be.
  • the temperature sensor is a silicone adhesive bonded to the pump housing is. This creates a uniform heat transfer of the temperature sensor by a comparatively large area Heat exchange surface reached, causing local temperature differences balanced and a measurement deviation can be prevented. At the same time achieved a simple assembly of the temperature sensor, the to do this using the silicone adhesive in one suitable position on the pump housing can.
  • An embodiment of the is also particularly advantageous present invention when the temperature sensor as a Thermistor with a positive or negative temperature coefficient is executed.
  • This allows the determination the temperature and therefore also the temperature dependent on it Flow of the pump in a simple way too reach without an electronic control unit. Thereby will use the pump even under difficult circumstances enables the pump to be so heavily used is that the use of electronic switching elements is excluded.
  • the one due to each Temperature changed electrical resistance of the thermistor therefore directly influences the funding performance of the for this purpose electrically operated pump.
  • Another particularly useful embodiment of the invention is achieved by the pump with an actuator to control the flow rate of the liquid based on the temperature detected by the temperature sensor the liquid is equipped. This will make it For example, possible if there is a deviation from a setpoint a diversion of the liquid into another line system to reach, for example, a bypass of the heating or cooling circuit.
  • the delivery rate the pump can both be changed at the same time as well as being kept unchanged, with the excess Amount of liquid for heating or cooling other components can be used.
