How Does the Wick and Orientation of a Heat Pipe Affect its Performance?

Heat pipes are used in a wide variety of applications, particularly in the aerospace, military and consumer electronics industries. A heat pipe is self-driven, two phase device used to transport heat from one end to the other. The liquid evaporates and turns to vapor on the heat pipe’s hot end (also known as the evaporator) where it then flows to the cold end (also known as the condenser) and liquifies. wick_type_structuresThe heat transfer ability of a heat pipe is determined by its diameter, fluid type, wick structure, and orientation. The Qpedia article, “How Wicks and Orientation Affect a Heat Pipes Performance” will review the different types of wicks and other factors that need to be considered when selecting a heat pipe for specific applications.
