  1. 1. Improving the Robustness, Thermal and Noise Performance of a Radio Transmitter Fan Tray

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Mattias Olausson; Selma Rahman; [2022]
    Nyckelord :Fan tray; Heat dissipation; Robustness; Radio transmitter; Noise performance; Fläktlåda; Värmeavledningsförmåga; Robusthet; Radio sändare; Ljudprestanda;

    Sammanfattning : With the growing demand of compact radio transmitters, so do the need for silent and efficient thermal management systems. Given the restricted form-factor, ensuring robustness of a unit with a detachable fan tray imposes a challenge. LÄS MER

  3. 2. Heat dissipation due to microvibrations in low temperature experiments

    Master-uppsats, KTH/Fysik

    Författare :Julien Witwicky; [2021]
    Nyckelord :Spatial cryogenics; Micro-vibrations; Heat dissipation.; Rymdkryogenik; Mikrovibrationer; Värmeavledning.;

    Sammanfattning : Ultra-sensitive photodetectors on-board space missions need very low temperatures to keep a good resolution. Cryo-coolers, such as pulse-tubes, help maintaining these conditions within a cryostat. In return however, they generate micro-vibrations. LÄS MER

  4. 3. Optimization of Heat Exhaust in the Edge of Tokamaks via Controlled Magnetic Stochastization

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Amit Kharwandikar; [2020]
    Nyckelord :Resonant Magnetic Perturbations; Tokamak; Divertor; Steady-state heat deposition; Power exhaust; Perturbation optimization; Resonant magnetiska störningar; Tokamak; avledare; statisk värmeavledning; värmeavledningen; störningsoptimering;

    Sammanfattning : The protection of plasma facing components from heat and particle overloads is paramount to ensure the operability and desired lifetime of magnetic fusion devices. The possibility of using external 3D magnetic perturbations to improve the steady-state heat exhaust in diverted tokamaks has been studied in this thesis. LÄS MER

  5. 4. Värmeavledning Vapenpipa : Utvärdering av luftkylningskoncept

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Industriell teknik

    Författare :Per Elfberg; [2019]
    Nyckelord :Erosion; Cooling; Heat transfer; Heat dissipation; heat exchanger; Gun barrel; värmeväxlare; värmeavledning; kylning; Vapenpipa; Eldrör;

    Sammanfattning : A gun barrels performance can only be considered satisfactory provided there is sufficient heat-dissipation, thus not hindering the tactical use of the unit and the weapon itself. The added energy to the barrel can potentially permanently change the material structure of the steel and create a hazard. LÄS MER

  7. 5. Modeling & Simulation of a Cooling Tower with COMSOL Multiphysics

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Matilda Lundberg; [2015]
    Nyckelord :kemiteknik; chemical engineering; model; cooling tower; Technology and Engineering;

    Sammanfattning : The aim of this project is to create a model of a Cooling Tower setup using COMSOL Multiphysics. Experiments are performed on the setup in order to provide data of the behaviour. The model is fitted to the data by estimate the models parameters. The parameter estimation is performed with MATLAB by connecting the programs using LiveLink, COMSOL 5. LÄS MER
