Cooling systems in electric vehicles is indispensable to ensure maximum performance of the systems when they are in operation. Of the known cooling methods such as air cooling, fan cooling, phase change material cooling and refrigerant cooling, indirect refrigerant cooling provides the best and most constant system temperature maintenance. The refrigerant, which is a mixture of water and glycol, circulates through the pipes, removing heat from areas having a higher temperature. The circulation of the refrigerant is handled by a hydrodynamic electrically driven centrifugal pump.
The purpose of this thesis is to design a test bench to measure the characteristics of pumps for cooling and heating systems in electric vehicles, with the emphasis on minimising the pressure loss of the system and allowing accurate measurements. The candidate shall characterise the turbine pumps used for this purpose at the test site and compare them with pumps using COR technology. The results should be analysed and further work suggested.
