In summary, heat pipes from Wakefield Thermal are a transport mechanism to move heat from the source to an area where the heat can be dissipated. Heat pipes do not actually dissipate the heat and are therefore incorporated into many different types of heat sinks as helpers. A heat pipe is a copper tube with an internal wick structure that is sealed on both ends with a small amount of water inside. As heat is applied to the pipe, the water will boil and turn to a gas, which then travels to the colder section of the heat pipe where it condenses back to a liquid. It is the evaporation and condensing of the water that forms a pumping action to move the water (and thus the heat) along the pipe. There are many types of wick structures that can be used within the heat pipe and they are generally classified as grooved, mesh, powder, and hybrid. The performance (amount of heat that can be transferred) of a heat pipe is a function of its length, diameter, wick structure, and overall shape. In cases where the amount of heat needed to be transported is too great for a single pipe, multiple pipes can be used in parallel and series to move more heat over greater distances. Wakefield Thermal's high performance heat pipes are used in many applications in various industries.
