System and Method of Boiling Heat Transfer Using Self-Induced Coolant Transport and Impingements

A method for cooling a heat-generating structure, the method comprising:

• transferring thermal energy from a heat generating structure to a plurality of pin fins disposed in a chamber, the plurality of pin fins including upstream pin fins and downstream pin fins;
• introducing a fluid coolant into the chamber;
• exposing the fluid coolant to the upstream pin fins disposed in the chamber, thereby causing at least a portion of the fluid coolant substantially in the form of a liquid to boil and effuse vapor during the transfer of thermal energy from the upstream pin fins to the fluid coolant, the effused vapor creating a self-induced flow in the chamber and creating a jet impingement of fluid coolant upon at least a portion of the plurality of pin fins;
• distributing non-vaporized fluid coolant substantially in the form of a liquid to the downstream pin fins through a spraying effect energized by the self-induced flow;
• and
• transferring at least a portion of the thermal energy from the downstream fins to the sprayed non-vaporized fluid coolant.

• distributing non-vaporized fluid coolant substantially in the form of a liquid to other portions of the structure using the self-induced flow;
• and
• transferring at least a portion of the thermal energy from the other portions of the structure to the distributed non-vaporized fluid coolant.
