  1. 6. Engine Thermal Management in Heavy Duty Vehicles

    Författare :Arne Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Control Simulation; Heat Exchangers; Heat Transfer; Thermal Management; Turbomachinery;

    Sammanfattning : Future regulations on noise and exhaust emissions have a large impact on heavy duty engine installations. Cooled EGR is used for NOx abatement. Better sealed engine encapsulations are used to meet new noise regulations. Engine thermal management is therefore becoming an increasingly important discipline. LÄS MER

    Sammanfattning : In hot humid regions the high outdoor temperature has negative effects on the indoor temperature of buildings that are not designed to cope with the local climate. This leads to discomfort for the occupants. LÄS MER

  4. 8. Developing strategies for improved economic performance and reduced climate impact of landfill mining in Europe

    Författare :John Laurence Esguerra; Joakim Krook; Niclas Svensson; Steven Van Passel; Anders Damgaard; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waste management; landfill management; resource recovery; sustainability assessment; emerging concept;

    Sammanfattning : Landfill mining refers to the re-circulation of resources from the previously deposited wastes. It is an alternative approach for managing landfills that integrates resource recovery with site remediation. LÄS MER

  5. 9. Graphene Heat Spreaders for Electronics Thermal Management Applications

    Författare :Yong Zhang; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; test platform; heat spreader.; transfer; Graphene; thermal management;

    Sammanfattning : Graphene shows great potential for applications in electronics due to its outstanding physical properties such as extremely high electron mobility, high thermal conductivity, high Young’s modulus and very high surface-to-volume ratio. Among these attractive properties, the high intrinsic thermal conductivity is a critical advantage for the application of graphene in electronics to alleviate heat dissipation problems. LÄS MER

    Författare :Xin Luo; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal conductivity; thermal interface material; thermal management; boron nitride fiber; electrospun nanofiber; lead-free solder; carbon fiber; nano-scale oxide layer; metal matrix composite;

    Sammanfattning : This thesis focuses on studies of nano-scale materials in electronic packaging applications with respect to following aspects: surface analysis of nano-scale oxide of lead-free solder particles, and thermal performance and mechanical property studies of nano-scale fiber and metal composite-based thermal interface materials. The composition and thickness of the solder oxide have a direct impact on the quality of interconnects and the reliability of a packaged system. LÄS MER
