Claim Text:
1. A method for cooling a heat-generating structure, the method comprising: transferring thermal energy from the heat-generating structure to a pin fin structure disposed in a chamber, wherein pin fins of the pin fin structure are arranged in a pattern with a first portion of the pin fins having a first shape and a second portion of the pin fins having a second shape, the second portion of the pin fins arranged along two sides of the pattern and in a row within the pattern; introducing a fluid coolant into the chamber; exposing the fluid coolant to at least a portion of the pin fin structure disposed in the chamber, thereby causing a portion of the fluid coolant substantially in liquid form to boil and effuse vapor during a transfer of the thermal energy from the at least the portion of the pin fin structure to the fluid coolant, the effused vapor creating a self-induced flow in the chamber; distributing the fluid coolant substantially in the liquid form to other portions of the pin fin structure using the self-induced flow; and transferring at least a portion of the thermal energy from the other portions of the pin fin structure to the distributed fluid coolant.
