Abstract
In one or more embodiments, one or more systems may comprise a heatpipe with a ratio between a cross-section area for a working fluid and one or more of a tube thickness and a wick thickness that is substantially constant along the length of the heatpipe. A heatpipe may have an evaporator section having a constant longitudinal profile and a condenser portion with a non-constant longitudinal profile. A wick inside the heatpipe may have a thickness based on a position in the heatpipe. The condenser portion may comprise a plurality of sections, with each section having a constant longitudinal profile.
