    Nyckelord :forced convection; heat transfer; pressure drop; turbulent; air cooling; bypass; plate; strip; pin; fin; heat sink; electronics; experimental; numerical; CFD; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Air cooling is still the dominant method for dissipating theheat produced by electronic components. In a typical electronicdevice, the components are situated on a Printed Circuit Board(PCB). For most applications natural convection is sufficientto cool the components. LÄS MER

  4. 3. Numerical Analysis of Heat Transfer and Fluid Flow in Heat Exchangers with Emphasis on Pin Fin Technology

    Författare :Hamid Nabati; Jafar Mahmoudi; Dan Loyd; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFD; Heat exchanger; Pin fin technology; Cooling system; Power transformers; CO2; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : One of the most important industrial processes is heat transfer, carried out by heat exchangers in single and multiphase flow applications. Despite the existence of well-developed theoretical models for different heat transfer mechanisms, the expanding need for industrial applications requiring the design and optimization of heat exchangers, has created a solid demand for experimental work and effort.

  5. 4. Modeling and Performance Analysis of Alternative Heat Exchangers for Heavy Vehicles

    Författare :Wamei Lin; Värmeöverföring; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Countercurrent flow; Graphite foam; Heat exchanger; Thermal performance; Computational fluid dynamics;

    Sammanfattning : Cross flow heat exchangers made from aluminum are common as radiators in vehicles. However, due to the increasing power requirement and the limited available space in vehicles, it is extremely difficult to increase the size of heat exchangers (HEXs) placed in the front of vehicles.
