“…The PCM-fin structure with low thermal resistance made BTMS operation time longer than without fin. Sun et al and Zheng et al [67,68] proposed a fin-enhanced structure composing of longitudinal fins and cylindrical rings to improve the heat transfer in the PCM module. The simulated analysis showed that the heat conduction networks formed by fin promoted the heat transfer from battery to PCM.…”

With the rapid development of electric vehicles (EVs), thermal safety issues have become increasingly prominent. In the charging and discharging process, a proper battery thermal management system (BTMS) can control the temperature of the power battery pack, which is essential to ensure the performance and safety of EVs. Among various cooling technologies, phase change material (PCM) cooling is widely used in BTMS due to its excellent characteristics, such as simple structure, good cooling effect, and no extra energy consumption. Herein, the research progress of PCM on BTMS is reviewed, including the overview of PCMs, the studies of single PCM‐based BTMS, and the development of hybrid PCM‐based BTMS. The results have found that the cooling performance of PCM‐based BTMS is determined by excellent PCM properties and suitable BTMS structure. In addition, the fin‐enhanced structure and active phase change slurry (PCS) can effectively improve the reliability and flexibility of BTMS applications. The hybrid BTMS consisting of PCM and other cooling technology can promote the heat dissipation of PCM, which helps to solve PCM heat saturation and further reduce the battery temperature. Finally, insufficient studies in current research are pointed out, and a future development direction is also reported.

“…2 The low thermal conductivity is a significant shortcoming of PCM, which reduces the melting/solidification rate and further decreases the effectiveness of the thermal management system. Therefore, various PCM thermal conductivity enhancement strategies have been investigated, such as adding nanoparticles into PCM, 3 embedding fins, 4 using porous matrices, 5 preparation of PCM/expanded graphite composite, 6 encapsulation, 7 and hybrid of different strategies. 8 Among these techniques, the utilization of metal fins and metal foam has been largely studied.…”

The thermal management systems or heat sinks are an integral part of electronic devices for aerospace applications. The heat transfer characteristics of the widely used phase change material (PCM)-based heat sinks under hypergravity conditions are essential in the designation of the heat sink. The current study conducts a systematic evaluation on the thermal characteristics of PCM coupled with hybrid fin-metal foam (FMF) structure under variable hypergravity conditions. A validated two-dimensional transient melting heat transfer model of the designed system is proposed, and the influences of enclosure orientation, fin height, PCM slab thickness, and the distribution of fin and metal foam under different hypergravity conditions are investigated. Results show that with the decrease in inclination angle, the melting time and the heating wall temperature become lower, and the optimal inclination angle is 0 . As the PCM slab thickness gets larger, natural convection is enhanced, while the heating wall temperature and melting time become larger. With the rise of hypergravity value, the effect of inclination angle strengthens, while the influence of PCM slab thickness weakens. Furthermore, with the rise of the copper foam fraction in the hybrid FMF structure, the melting time and the heating wall temperature firstly decrease and increase afterward. The optimal copper foam fraction is 58.62%. This study guides the optimal design of the PCMbased heat sink in aerospace applications.

When a lithium-ion battery works under high current, its working temperature is easy to exceed the allowable working temperature, resulting in the decrease of battery life. This may cause the non-uniformity of the internal working temperature of the battery and affect the working parameters of the battery. Therefore, an effective thermal management system is needed to enhance the thermal performance of the battery, improve the work efficiency, and extend the service life of the battery. In this study, we propose a new type of fork type mini-channel cooling plate based on genetic optimization algorithm to reduce the working temperature of battery and obtain better thermal uniformity.First, the thermal performance of co-current type cooling plates is experimentally and numerically studied. The heat transfer ability of cross flow cooling plates used to cool the Li-ion Battery is evaluated by parametric method. Second, a multi-objective genetic algorithm optimization is finally performed, considering the balance of the maximum value for temperature and pressure drop.Compared with the previous study, the reduction of temperature difference of this cooling plate can be up to 2 C. In contrast, the pressure drop penalty and thermal resistance of the optimized cooling plates can be reduced by 20% and 40%, respectively. Thirdly the thermal performance of a battery module with eight battery cells is also examined numerically. The maximum ΔT of the battery pack among cells is 4.83 C for V = 48 mL/s, which implies that the battery pack can work normally. This study indicates that batteries with the proposed new cooling plates have much better temperature uniformity.
