“…Furthermore, when the coolant flows through the manifolds, it will impinge on the substrate surface directly and heighten the heat exchanger at the impingement point. Considering this, many researchers have proposed the concept of the MMC [207][208][209][210].…”

The heat dissipation density of electronic devices is increasing dramatically, which causes a serious heat bottleneck in electronics. Operating temperature over its rated temperature results in performance deterioration and even device damage. With the development of micro-machining technologies, microchannel heat sinks have become one of the best ways to remove the considerable amount of heat generated by the high-power electronics. It shows the advantages of large specific surface area, small size, saving coolant and high heat transfer coefficient. This paper comprehensively overviews the research progress in microchannel heat sinks and generalizes the hotspots and bottlenecks of this area. The heat transfer mechanisms and performances of different channel structures, coolants, channel materials and some other influence factors are reviewed. Besides, this paper classifies the heat transfer enhancement technology and reviews the related studies on both the single-phase and phase-change flow and heat transfer. The comprehensive review is expected to provide theoretical reference and technical guidance for further research and application of microchannel heat sinks in the future.

“…The study indicated that the wavy wall microchannel performed better heat dissipation at a higher inlet velocity, while at a low inlet velocity, the metal foam embedded microchannel can cool down the battery cell with higher performance and lower power consumption. Ki et al [36] developed a BTMS including a metal foam as a cooling passage in a 24-pouch cell battery module. The study revealed that with a 4.2 times lower flow rate, the system could attain an optimal temperature and temperature deviation of less than 2 • C. In a study conducted by Weng et al [37], various fin structures such as V, Y, and X shapes were designed and utilized as heat flow channels in a PCM enclosure.…”

The battery thermal management system (BTMS) for lithium-ion batteries can provide proper operation conditions by implementing metal cold plates containing channels on both sides of the battery cell, making it a more effective cooling system. The efficient design of channels can improve thermal performance without any excessive energy consumption. In addition, utilizing phase change material (PCM) as a passive cooling system enhances BTMS performance, which led to a hybrid cooling system. In this study, a novel design of a microchannel distribution path where each microchannel branched into two channels 40 mm before the outlet port to increase thermal contact between the battery cell and microchannels is proposed. In addition, a hybrid cooling system integrated with PCM in the critical zone of the battery cell is designed. Numerical investigation was performed under a 5C discharge rate, three environmental conditions, and a specific range of inlet velocity (0.1 m/s to 1 m/s). Results revealed that a branched microchannel can effectively improve thermal contact between the battery cell and microchannel in a hot area of the battery cell around the outlet port of channels. The designed cooling system reduces the maximum temperature of the battery cell by 2.43 °C, while temperature difference reduces by 5.22 °C compared to the straight microchannel. Furthermore, adding PCM led to more uniform temperature distribution inside battery cell without extra energy consumption.
