灵活的热管包括蒸发器和冷凝器之间的波纹管，允许在热管的导热区和输出部分之间动态移动。热管的灵活性增加了热管两端之间的运动范围、组件的耐用性以及平均故障之间的时间 （MTBF）。
通过将柔性热管与其他热管理技术相结合，工程师可为具有挑战性的应用创建创新的冷却系统。常见的配置包括连接到柔性热管一端的热源上的蒸发器板，以及用于散热冷凝器端的散热，以进行完整的柔性热管组件。
博伊德公司的柔性热管使工程师能够将热发电部件放置在最佳位置，以最大限度地提高服务性和可靠性，同时克服恶劣的热和环境条件。设计师可以自由地指定组件，如移动执行器和远程终端的位置，优化整个系统，而不牺牲热量。增加的灵活性还有助于简化狭小空间的安装和维护。这使得灵活的热管总成成为军事、航空航天和航空电子设备设计中的有效解决方案，而空间处于溢价状态。
Flexible Heat Pipes are made from a wide range of metal materials and use a variety of working fluids depending on the application. Boyd's Flexible Heat Pipes can be installed in either gravity-aiding or against-gravity orientations because our proprietary flexible wick structures return working fluid to the evaporator section of the heat pipe. These specialized wick structures also increase the overall lifespan and reliability of Flexible Heat Pipe Assemblies without sacrificing performance. Boyd Flexible Heat Pipes have been successfully thermal cycled from -55° C to +65° C and flex fatigue tested to more than 5 million cycles with no sign of failure. Some of Boyd’s customized Flexible Heat Pipe Assemblies can also accommodate shock, vibration, and acoustic requirements, freeze/thaw cycled between -60° C and 135° C, and withstand test procedures for extreme aircraft equipment such as F-18 aircraft.
