Abstract
A liquid-cooled battery thermal management systems (BTMS) has been widely employed as an effective approach for electronic vehicles to ensure battery safety. However, the common linear flow channel structure induces a serious non-uniform temperature distribution. In this study, the novel taper-type manifold channel heat sink with multi-channel passes is proposed to improve battery temperature uniformity and reduce power consumption of BTMSs. The maximum battery temperature and temperature difference, temperature maldistribution parameter and power consumption performance of eight different designs are analyzed and compared. Moreover, the effectiveness of delayed cooling strategy on the temperature uniformity based on liquid-cooled system were analyzed as well. The results show that adopting the taper-type manifold structure can improve the cooling performance of BTMSs, while increasing the number of channel passes improves the thermal performance at the cost of increased power consumption. The taper-type manifold structure with three channel passes has the best cooling performance, in which its power consumption is reduced by 86.3% compared to the base case within the battery temperature and temperature difference limits. Furthermore, delayed cooling scheme is not found to be a good strategy for BTM since it will accumulate a large temperature difference in a very short period when the coolant starts to turn on. These results are of great significance to the design of advanced liquid cooling BTMS.
期刊介绍：
Thermal Science and Engineering Progress (TSEP) publishes original, high-quality research articles that span activities ranging from fundamental scientific research and discussion of the more controversial thermodynamic theories, to developments in thermal engineering that are in many instances examples of the way scientists and engineers are addressing the challenges facing a growing population – smart cities and global warming – maximising thermodynamic efficiencies and minimising all heat losses. It is intended that these will be of current relevance and interest to industry, academia and other practitioners. It is evident that many specialised journals in thermal and, to some extent, in fluid disciplines tend to focus on topics that can be classified as fundamental in nature, or are ‘applied’ and near-market. Thermal Science and Engineering Progress will bridge the gap between these two areas, allowing authors to make an easy choice, should they or a journal editor feel that their papers are ‘out of scope’ when considering other journals. The range of topics covered by Thermal Science and Engineering Progress addresses the rapid rate of development being made in thermal transfer processes as they affect traditional fields, and important growth in the topical research areas of aerospace, thermal biological and medical systems, electronics and nano-technologies, renewable energy systems, food production (including agriculture), and the need to minimise man-made thermal impacts on climate change. Review articles on appropriate topics for TSEP are encouraged, although until TSEP is fully established, these will be limited in number. Before submitting such articles, please contact one of the Editors, or a member of the Editorial Advisory Board with an outline of your proposal and your expertise in the area of your review.
