Investigation of a Low-Power-Consumption and Self-Retaining Micro Solenoid Valve for Thermal Management Systems

• The proposed low-power-consumption miniature solenoid valve (LMSV) achieves fast switching (3 ms), low pressure loss (200 Pa at 0.92 L/min), and low energy consumption (1.55 J per cycle) through a self-retaining permanent magnet design. • A straight-through valve design with an internal electromagnetic actuator minimizes flow resistance, enhancing the efficiency of thermal management systems. • Multiphysical coupling analysis and experimental validation demonstrate the valve's robust performance across varying temperatures, ensuring reliable operation in data center cooling applications. • The LMSV addresses the critical need for active flow control in parallel branches of thermosyphon loops, offering a miniaturized solution that reduces energy consumption and improves system flexibility.
