Heat generation from CPU of personal computer has increased, so more efficient cooling system is needed. This paper presents the result on performance of cooling system using two-phase natural circulation loop as a candidate for this purpose. Boiling on a finned surface that simulates CPU caused two-phase natural circulation. Results of boiling heat transfer showed higher value than Rohsenow-Clark correlation as the system pressure decreases. Also, this might be attributable to the effect of the finned surface. Possibility of cooling system by two-phase natural circulation loop was confirmed. By improving the condenser performances, the system can be applicable to the actual personal computer.
