In this study, a numerical analysis study on the heat transfer characteristics according to the opening and closing of the hydrogen shut-off valve was performed, and the temperature distribution of the key components of the hydrogen shut-off valve was predicted through the result. The ANSYS CFX program was used to predict the heat transfer characteristics of the hydrogen shut-off valve. When the hydrogen shut-off valve was open, the average temperature of the O-ring, which prevents hydrogen leak inside the solenoid valve, was approximately -40℃, and the plunger showed a maximum of -40℃ and a minimum of -110℃. When the hydrogen shut-off valve was completely closed, the O-ring showed approximately 24.82℃ and the plunger showed approximately 24.71℃, which were almost at room temperature.
