Abstract
A closed loop, two-phase thermosiphon system is an efficient method for dissipating high heat fluxes from a hot spot to a secondary coolant with a small temperature drop. At KTH in Stockholm, several prototypes of such systems have been built and tested over the past years. In this paper heat transfer coefficients for boiling and condensation with the refrigerants R142b, R134a, R22 and propane (R290) are presented, analysed and compared to correlations from the literature. The influence of channel diameter on boiling heat transfer is also examined.
