Abstract

This study has been carried out to investigate thermosyphon's geyser boiling phenomenon used to solar collector. evaporator section of thermosyphon used to solar collector is very much longer than that of condenser section. From the results from this study, Geyser boiling's cycle depends on cooling water, tilt angle and the applied heat load at the evaporator. In this study, according to heat load, the geyser boiling frequency is lower, but the amplitude higher. For the high tilt angle of heat pipe, the frequency and amplitude are lower and higher in the evaporator region, respectively. Whereas, these phenomena is in contrast in the condenser region.
