Technologies provide a heat pipe having a controlled torque resistance. The techniques disclosed herein provide a heat pipe that can function as a coupling device and as a thermal interface between two moving components of a device without the need of a mechanical hinge. In some configurations, a heat pipe comprises a housing having an outer surface and having an inner surface defining a cavity. The heat pipe can also comprise one or more components for transferring heat from a first region to a second region. In addition, the heat pipe is configured to provide a predetermined torque resistance about a first axis that is perpendicular to a longitudinal axis of the heat pipe. Components, such as a heat source and a heat sink, that are attached to the heat pipe can be hingeably coupled with a predetermined torque resistance without requiring a hinge and a separate thermal interface device.
