Cooling of Electronic Components by an Aluminum Loop Thermosyphon Containing Two Evaporators and One Condenser

The article presents the results of studies of the parameters of a new flat aluminum thermosyphon, the evaporator of which contains two identical parallely operating panels, each of which has 8 minichannels. The panels are united by single vapor and liquid collectors. The working fluid is acetone. A study was carried out to investigate the influence of a thermal load and the degree of thermosyphon filling with working fluid on the heat exchange coefficients of the evaporator and condenser, as well as on the thermal resistance of the thermosyphon.
