• Komponentenvermessung und -optimierung

Component measurement and optimization

Additionally to the development, testing and optimization of entire cooling circuits we measure and optimize single components. Our performance portfolio includes:

  • Measurement, investigation and optimization of all cooling circuit components like: electric pumps, throttles, check valves, cycle valves respectively delivery volume, pressure loss, creation of pressure peaks and service life
  • Measurement and adjustment of thermostats regarding pressure behaviour, control (opening point) and their characteristics over life-span
  • Measurement of e.g. intercooler, AGB, HWT, ZWK respectively their characteristics under pressure, temperature and volume flow variation (static & dynamic)
  • Test rigs for components work and measure in a temperature range of -40°C to +130°C
  • Defoaming of the coolant by e.g. optimization of chamber geometry: arrangement and design of breaches of chambers and prevention of cascades creation
  • Investigations under extreme loads (acceleration, cornering etc.)
  • Construction of steam cushion
  • Positioning of warning signal transmitter

Thermal shock

  • Determination of position out of damage, calculation or infrared camera
  • Appliction of DMS
  • Measurment of test piece on test rig and car
  • Results evaluation
  • Deduction of measures

Testing of water pumps

  • Electric motor drive of 15 kW
  • Conditioning construction for coolant temperatures from -40°C to +130°C
  • Proportional throttle in order to create counterpressure after the water pump
  • Pressure control unit for system pressure (0 to 4 bar rel.)
  • Sampling rate up to 200 Hz for:
    - temperature
    - throughput and
    - power consumption water pump drive
