摘要：
This study reports a high-performance heat spreader based on room-temperature liquid metal coolant. Conceptual cooling experiments show that liquid metal heat spreader owns particularly excellent heat spreading performance. In order to evaluate the driving features of liquid metal, a miniaturized electromagnetic pump with high reliability and low power consumption was fabricated and tested. Extreme experiments were performed and showed that liquid metal heat spreader could overwhelm all the latest typical advanced spreading technologies and serve as an ultimate heat spreading solution under extremely high heat flux density condition. © 2012 American Society of Mechanical Engineers.
