System and Method for Boiling Heat Transfer Using Self-Induced Coolant Transport and Impingements
First Claim
1. A cooling system for a heat-generating structure, the cooling system comprising:
- a fluid coolant;
a chamber having an inlet and an outlet, the inlet operable to receive a fluid coolant into the chamber substantially in the form of a liquid, the outlet operable to dispense of the fluid coolant out of the chamber at least partially in the form of a vapor;
a structure which directs a flow of the fluid coolant substantially in the form of a liquid into the chamber through the inlet;
a structure disposed in the chamber, the structure operable to receive thermal energy from the heat generating structure and transfer at least a portion of the thermal energy to the fluid coolant, the thermal energy from the heat-generating structure causing at least a portion of the fluid coolant substantially in the form of a liquid to boil and effuse vapor upon contact with a portion of the structure; and
wherein the effusion of vapor creates a self-induced flow in the chamber, the self-induced flow distributing non-vaporized fluid coolant substantially in the form of a liquid to other portions of the structure.

Abstract
According to one embodiment of the invention, a cooling system for a heat-generating structure comprises a chamber and structure disposed within the chamber. The chamber has an inlet and an outlet. The inlet receives fluid coolant into the chamber substantially in the form of a liquid. The outlet dispenses the fluid coolant out of the chamber at least partially in the form of a vapor. The structure disposed within the chamber receive thermal energy from the heat generating structure and transfers at least a portion of the thermal energy to the fluid coolant. The thermal energy from the heat-generating structure causes at least a portion of the fluid coolant substantially in the form of a liquid to boil and effuse vapor upon contact with a portion of the structure. The effusion of vapor creates a self-induced flow in the chamber. The self-induced flow distributes non-vaporized fluid coolant substantially in the form of a liquid to other portions of the structure.

18. A method for cooling a heat-generating structure, the method comprising:
-
transferring thermal energy from a heat generating structure to a structure disposed in a chamber;
introducing a fluid coolant into the chamber;
exposing the fluid coolant to at least a portion of the structure 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, the effused vapor creating a self-induced flow in the chamber;
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 structure disposed in the chamber to the fluid coolant. - View Dependent Claims (19, 20)
