Patent ID: 7191820

Claim:
A method of manufacturing a heat reservoir device for managing a heat input from a component subject to transient conditions and having space constraints defined by a first volume of available space surrounding the component, the heat reservoir device comprising: providing a heat transfer subsystem comprising a heat transfer component incorporating a thermosiphon loop, a solid or substantially solid, high-conductivity material, or a closed liquid loop path, the heat transfer subsystem having a first end thermally coupled to the component and a second end thermally coupled to a heat storage subsystem; providing a heat collector thermally coupled to the heat transfer subsystem and the heat input, the heat conductor having a block of conductive material positioned in direct contact with a heat source; and providing a heat rejection subsystem coupled to the heat storage subsystem, wherein: the heat storage subsystem is remotely situated from the heat input, outside the first volume of available space, and comprises a phase change material capable of changing phases in response to the transient conditions causing the temperature of the phase change material to rise above its phase change temperature, the phase change material selected such that its transition temperature is less than the maximum operating temperature of the heat input and greater than the steady state temperature of the heat input at its nominal heat emitting state, and the heat rejection subsystem and the heat storage system have a combined volume that is greater than the first volume of available space.
