Om tjänsten

Scania is now undergoing a transformation from being a supplier of trucks, buses and engines to a supplier of complete and sustainable transport solutions.

Background:

 In electrified vehicles , the cooling fan provides air flow to the battery cooling circuit, component cooling circuit and electric machine circuit. In heavy electrified vehicles there is a need for higher cooling capacity.

Therefore we need larger electrical fan with higher power and sometimes several cooling fans.

 Assignment:

 The project assignment is to study different factors in cooling fan design in order to achieve optimized cooling capacity and air flow in electrified vehicles’ cooling system.

  • Study on optimizing air flow through cooling fan and reaching less noise level
  • Investigation of different installation parameters in order to achieve higher efficiency

Example: distance from the radiator, the angle from radiator etc.

  • Comparison between electrical cooling fan’s efficiency and mechanical cooling fan’s efficiency
  • Study on motor design, what optimal power we need for different blade designs in order to meet required cooling capacity
  • Benchmark of different fan designs to investigate noise level

 Education:

Master (civilingenjör), elektronik, Elkraftteknik, Maskinteknik, Farkost, mekanik, mekatronik.

Knowledge of Matlab, simulink and CFD are a plus.
