Abstract

A high performance heat pipe and the method for constructing it. A unique wick structure of sintered metal is formed directly into the heat pipe casing and contains simultaneously formed tunnels which permit the flow of large quantities of liquid with low pressure loss. A method of constructing a hybrid structure with heat pipe sections at both ends of a section used to transport the internal liquid and vapor over long distances is also included.
