摘要：

This letter presents a micropillar-pumped polymer loop heat pipe (LHP) with potential applications in flexible electronics. A unique evaporator with a micro pillar wick was designed for a flexible polymer LHP. The polymer LHP was fabricated via simple and cost-effective soft lithography, omitting the need for a porous wick. This design and fabrication approach facilitated passive two-phase cooling in the polymer LHP, with up to 34 C-degrees reduction in evaporator temperature when compared to a non-fluid-charged state in a horizontal orientation.
