“…14). These cooling solutions offer impressive results [30], however, such systems experience a significant effect of module load cycles, ambient conditions and component orientation on the performance. Aside from heat pipe-based cooling systems, two-phase cooling is not typically used for cooling power electronics at present.…”

-Thermal management is a crucial step in the design of power electronic applications, especially railroad traction and automotive systems. Mass/size parameters, robustness and reliability of the power electronic system greatly depend on the cooling system type and performance. This paper presents an approximate parameter estimation of the thermal management system required as well as different commercially available cooling solutions. Advantages and drawbacks of different designs ranging from simple passive heatsinks to complex evaporative systems are discussed.

“…Evaporative cooling was adopted for its feature of dissipating high heat flux at a relatively lower expense. 25,26 Coolant droplets dissipate excessive heat from the surfaces to reach a desired cooling effect through evaporation. Unlike principal other cooling methods that need extra equipment (pump, cooling plates, or heat exchanger), evaporation is a natural process in the environment, which requires the minimum energy consumption during the operation process.…”

“…Compared with single-phase forced convection, evaporation-based cooling method involves a phasechange process (from liquid to vapor), which provides better cooling performance. 25 The latent heat of the coolant's vaporization process is the crucial factor for heat dissipation. Kumari et al 27 investigated the cooling efficiency of the mist evaporation-based thermal management system through analytical and numerical analysis.…”

Lithium-ion battery packs' discharging results in significant heat generation, which leads to safety issues and negative impact during the application of electric vehicles. Previous studies focused more on the configurations and design of cell packs/modules with a cooling system to control the battery cell's temperature. However, temperature differences are more difficult to control to ensure thermal uniformity. Maximum pressure is a significant parameter that affects energy consumption and the cost of the cooling system. This study proposed a comprehensive approach to design an efficient mist cooling system, which considered both maximum temperature and temperature standard deviation. This design method generates candidate design points by Latin Hypercubes Sampling and design of experiments (DOEs); effects of some significant parameters of the cooling structure on the cooling efficiency are evaluated by sensitivity analysis. Surrogate models are then selected and optimized by the multi-objective optimization approach to acquire an optimal scheme of the mist cooling structure. The optimized results showed that the optimized mist cooling battery module has better thermal performance with a lower cost. This approach can be used in the battery pack design process to control the temperature rise and temperature distribution, and energy consumption of the cooling system.
