Abstract
A heat pipe for cooling a heat-generating component has a generally planar, sealed flexible body having an evaporator section, a condenser section, and a flexible bellows section. The bellows section is located between the evaporator section and the condenser section along a longitudinal length of the body. A chamber extends from the evaporator section to the condenser section inside the body and contains a working fluid. The bellows section includes internal supports to keep the chamber open during repeated bending of the heat pipe at the bellows section.
