O livro explora o rápido crescimento da indústria de veículos eléctricos e a necessidade de sistemas eficientes de gestão do calor nas suas baterias. Centra-se no papel dos nanofluidos, uma tecnologia de ponta, na melhoria da dissipação de calor para um melhor desempenho e longevidade da bateria. A análise abrange a composição dos nanofluidos, os métodos de arrefecimento (activos e passivos) e as estratégias de gestão térmica. Destaca os potenciais benefícios da utilização de nanofluidos para arrefecer os sistemas de baterias de veículos eléctricos, conduzindo a uma maior eficiência e segurança. No entanto, o livro também aborda o debate em curso sobre a melhor composição de nanofluidos e discute limitações como a estabilidade, o custo e o impacto ambiental que requerem mais investigação.

The book explores the rapidly growing electric vehicle industry and the need for efficient heat management systems in their battery packs. It focuses on the role of nanofluids, a cutting-edge technology, in enhancing heat dissipation for improved battery performance and longevity. The review covers nanofluid composition, cooling methods (active and passive), and thermal management strategies. It highlights the potential benefits of using nanofluids to cool EV battery systems, leading to increased efficiency and safety. However, the book also addresses the ongoing debate around the best nanofluid composition and discusses limitations such as stability, cost, and environmental impact that require further research.

Constructal theory is widely used as a powerful tool in designing of engineering systems (flow configurations, patterns, geometry). This theory is observed in nature and its principles are applicable to general engineering. Constructal theory encompasses a wide range of space in the ¿design¿, drawing from each and every field from engineering to biology. The universal design of nature and the constructal law unify all animate schemata such as human blood circulatory systems, and inanimate systems, such as urban traffic and river basins. The proceeding research applies the overlying theories of constructal theory to the two different systems in order to achieve best thermal performance phenomena. First is stabilization of roadway embankments in the permafrost regions with design modifications in existing thermosyphon evaporators with tree structure designs, and defining the optimal spacing between two neighboring thermosyphons based on thermal cooling phenomena. The second part of the research is to find an effective way to reject heat released from the metal hydride powder to the outer environment during the hydrogen absorption process.
