Research Studentship in Power Electronics Thermal Management
Research Studentship in Power Electronics Thermal Management
Project: Power electronics thermal management.
3.5-year D.Phil. studentship
Supervisors: Prof Edmond Walsh
The studentship will be based at the Oxford Thermofluids Institute within theDepartment of Engineering Science at the University of Oxford.
With the commitment to transition from fossil fuels to sustainable energy sources there is an increasing requirement for power electronics in many applications; for example wind turbines to next generation of aircraft and spacecraft. For such applications cost and weight are major considerations, and hence there is a continuous drive to make devices smaller and lights while simultaneously dissipating more heat.
Immersion cooling and phase change (boiling/evaporation) result in some of the largest heat transfer coefficients of any cooling mechanism. This project will theoretically and experimentally investigate boiling heat transfer, using cryogenic and fluorocarbon fluids, with various surface geometries and treatments to evaluate optimum design. Key objectives will be to reduce weight and volume while simultaneously increasing heat dissipation. The project will initially start with immersion cooling and progress to flow boiling using cryogenic fluids.
