Abstract

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 reduction in evaporator temperature when compared to a non-fluid-charged state in a horizontal orientation.

微柱泵浦聚合物环路热管的设计与制造

这封信介绍了一种微柱泵浦聚合物环路热管(LHP)在柔性电子产品中的潜在应用。为柔性聚合物LHP设计了一种独特的微柱芯蒸发器。聚合物LHP是通过简单而经济的软光刻技术制造的，省去了多孔芯的需要。这种设计和制造方法促进了聚合物LHP的被动两相冷却，与水平方向的非充液状态相比，蒸发器温度降低了34°C。(2023 - 0140)
