The thermosyphon consists of a heated wall and a parallel cooled wall with a gap of a certain width in between. Vapor phase is generated through boiling on the heated wall, and is condensed by the cooled wall. Characteristics regarding the enhanced heat transfer coefficient and critical heat flux are discussed. The results have a potential to be applied in electronic devices, turbines and solar systems.application/pdfengThermal diffusivityHeat-transfer mediaHeat -- TransmissionThesis
