Steadily increasing demands for power, acceleration and range of electric vehicles produce larger battery heat-dissipation densities. Conventional cooling principles, including liquid cooling primarily used in high performance electric cars, are slowly reaching their limits regarding cooling capabilities and temperature regulation. This created a need for development of novel technology with greater cooling capabilities, giving potential for continuous car battery improvement in the future. Two-phase spray cooling technology is successfully used in military and space industry, but there is scarce additional information available. The aim of this thesis is to gather information about two-phase spray cooling technology through research, and to develop testing equipment for evaluating technology implementation possibilities to serve as automotive battery cooling systems.
