Abstract
A method of forming a phase change passive heat sink, with a base member and heat dissipating members, is provided. The base member is hollow and defines an evaporation chamber therein. A number of heat dissipating members are connected to the base member. Each of the heat dissipating members are substantially tubular in configuration with a closed end and an open end and defining respective condensation chambers therein. The open ends of the heat dissipating members are connected to the base member with the condensation chambers and are in fluid communication with the evaporation chamber. A heat transporting media resides in the base member which is movable into the condensation chambers upon application of heat to the base member. Heat is dissipated through the heat dissipating members.
