液滴散热器（ldr）可以比先进的热管散热器轻5到10倍。它们几乎不受穿刺的影响，体积很小，而且很容易部署。系统研究表明，对于液体锂、锡和铝，它们的优化功率为10至100兆瓦，对于NaK和真空油，它们的优化功率为几百千瓦。更大的散热器可以由这些尺寸的模块构成。针对轻LDR质量重新优化的电源系统在100 K的低排斥热温度下运行，并且可能比使用传统散热器的电源系统轻3到5倍。最近的收集器测试表明，无飞溅的运行机制有望提高收集效率。在不久的将来，在空间进行低阻试验应该是可行的。
Liquid-droplet radiators (LDRs) can be as much as 5 to 10 times lighter than advanced heat pipe radiators. They are virtually immune to puncture, stow in a small volume, and are easily deployed. Systems studies show that they optimize in the 10to 100-MW size for liquid lithium, tin, and aluminum and at several hundred kilowatts for NaK and vacuum oils. Larger radiators can be constructed from modules of these sizes. Power systems reoptimized for the light LDR mass operate at 100 K lower reject heat temperatures and may be 3 to 5 times lighter than those using conventional radiators. Recent collector tests have revealed a splash-free regime of operation promising high collection efficiencies. LDR tests in space should be feasible in the near future.
