Design and Electromagnetic Force Simulation for Solenoid Valve of Mobile Refrigeration Equipment

In order to analyze the effect of the solenoid valve parameters on electromagnetic force and retention force at different thickness of coil frame and different temperatures conditions. The electromagnetic valve in the refrigeration system is used as an example to simulate the electromagnetic force and retention force based on ANSYS in this study. The electromagnetic force is greater than 11.1 N under typical working condition of 80 ℃. It’s greater than 9.4 N under extreme working condition of 130 ℃. The thickness of the magnet is more than 0.8 mm (weight 8 g) and the electromagnetic force is more than 16 N. Compared with the conventional thickness of 1.5mm magnet (17g), the weight can be reduced by 46%. The results suggest that the electromagnetic force and retention force of solenoid valve can be simulated through finite element analysis. The thickness of 0.8 mm can meet the air gap conditions of 0.8mm and the power less than 10W. References can be provided for the design.
