The purpose of this study is to apply cooling system of inverter used in turbo chiller to water cooling system. The existing air cooling system has a disadvantage in that it has a large volume that affects the heat sink depending on the use environment. To overcome these drawbacks, this study investigated the cooling system of water cooled inverter. ANSYS CFX16.1 was used to optimize the cooling system. The inlet temperature of the cooling water was 30 ° C, and the turbulent flow model of the cooling water flow was the k-ε model. Experimental conditions were 30 ℃ for cooling water inlet temperature, 300, 500, 800, 1500W for heat input. Optimized water-cooled winches were directly machined using a CNC machine tool and the experimental and CFX analysis data were compared. The average surface temperature of the heat sink was about 2.2% higher than that of the water-cooled cooling system when the heat input was 1500 W and the mass flow rate of the cooling fluid was 0.05 kg / s. Cooling heat showed that the cooling heat of the water cooling system was about 79.3% higher than that of the air cooling system.
