Heat pipes are great thermal energy transporters that use an evaporator and condenser in place of a solid conductor. When a liquid is converted into a vapor, the working fluid within the heat pipe can absorb larger amounts of heat without a significant increase in temperature. Heat pipes are used to move heat away from high density power sources. They can do this by either spreading heat in a base plate or by transferring heat directly into fins.
Heat pipes do not dissipate heat themselves so are often used in conjunction with other advanced cooling technologies creating a heat pipe assembly. Common technologies used in heat pipe assemblies include bonded fin, zipper fin, and folded fin but are not limited to these options. Integrating heat pipes into a system can enable the use of additional technologies for application with high density power loads, enclosed or limited space, weight restrictions, or limited airflow.
