Heat Pipe Basics and Demonstration Video

Check out our new version of this video here: https://youtu.be/51bwzEO8XCw This video from ACT (www.1-act.com) provides a brief, high-level overview of the thermodynamic properties occurring during heat pipe operation. It also provides a real-life visual demonstration of the performance enhancements of heat pipes over copper. A heat pipe consists of a working fluid, a wick structure, and a vacuum-tight containment unit (envelope). The heat input vaporizes the working fluid in liquid form at the wick surface in the evaporator section. Vapor and its associated latent heat flow toward the colder condenser section, where it condenses, giving up the latent heat. Capillary action then moves the condensed liquid back to the evaporator through the wick structure. Essentially, this operates in the same way as how a sponge soaks up water. Phase-change processes and the two-phase flow circulation in the heat pipe will continue as long as there is a large enough temperature difference between th
