Abstract: Aiming at the heat problem of magnetostrictive actuator when it works, the velocity and pressure of coolant in its internal cooled system was studied. The existed cooled system was analyzed through theoretical analysis method. A new type of water immersion cooled system was proposed, which improves the space utilization rate by about 5% and enlarges the effective contact space by about 4.32 ml. The physical parameters of the cooled fluid in the new cooled system was simulated and analyzed by ANSYS Workbench software, and orthogonal experiments on the data of the physical parameters of the cooled fluid in the cooled scheme model was carried out by SPSS software. The results indicate that the velocity of coolant in the cooling system has obvious restraint effect on the temperature of the actuator. The pressure at the inlet and outlet of the coolant has no restraint effect on the temperature of the actuator. This conclusion is verified by the experimental design method.
