摘要
The microchannel heat sink is an effective technology for the thermal management of Li-ion batteries. The overall performance of two heat sinks with improved thermal management of Li-ion batteries was determined by a numerical simulation model. A manifold microchannel heat sink (MMC) and a traditional microchannel heat sink (TMC) with different aspect ratios of microchannels were developed. Thermal transfer performance and pressure drop characteristics of two heat sinks were compared by Fluent. Results indicate that the temperature uniformity of the TMC is worse than that of the MMC. The total pressure drop of TMC is significantly higher as compared to that of the MMC. Consequently, the MMC has a better overall performance than the TMC.
