Experimental Study on the Small Two-phase Thermosyphon Loop with Minichannel Evaporator

Abstract This study experimentally investigates the small two-phase thermosyphon loop with minichannel evaporator. The influences of heating power, fan power, and inclination angle on the heat transfer performance are presented and the related mechanisms are revealed. Results show that the thermal resistance of the thermosyphon loop tends to decrease as the heating power is increased. It is found that there exists an optimal value of fan power. Interestingly, the invalidity behavior of thermosyphon under the inclination condition prefers to occur at higher heating power. To sum up, the small two-phase thermosyphon loop with minichannel evaporator could produce the excellent heat transfer performance with energy-saving characteristics, indicating its wide potential applications in the field of electronic chip cooling.
