High Efficiency Thermal Management System

摘要

Disclosed are methods and apparatuses for cooling a work piece surface using two-phase impingement, such as direct jet impingement. Preferred method include flowing a coolant through a chamber comprising a surface to be cooled by projecting a jet stream of coolant against the surface while maintaining pressure in the chamber to permit at least a portion of coolant contacting the surface to boil. Preferred apparatuses include a chamber comprising the surface and tubular nozzles configured to project a stream of coolant against the surface, a pump for forcing coolant through the tubular nozzles, a pressurizer for maintaining an appropriate pressure in the chamber, and a heat exchanger for cooling the coolant exiting the chamber. The apparatuses may further include a pressure regulator for detecting changes in temperature of the coolant exiting the chamber and communicating with the pressurizer to adjust the maintained pressure accordingly. The methods and apparatuses disclosed herein provide for effective and efficient cooling or work piece surfaces.

1. An apparatus for cooling a surface with a coolant, comprising:
an enclosed chamber having an interior, an opening adapted for receiving the surface therein such that the surface communicates with the interior of the chamber, an inlet and an outlet, the inlet and the outlet being configured for flowing the coolant through the interior of the chamber in a stream projected against the surface and exiting the coolant through the outlet; a pump having an input in fluid communication with outlet of the chamber through a first path and an output in fluid communication with inlet of the chamber through a second path, the pump configured to project the stream of coolant through the inlet into the chamber and against the surface; and a pressurizer in fluid communication with the first path to adjust the pressure of the coolant flowing in the first path from the outlet of the chamber to the input of the pump.
