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.

According to one embodiment, a radome includes two dielectric layers separated by an internal layer. The internal layer is configured with an internal cooling system including a fluid channel that receives a fluid through an inlet port, conducts heat from the radome to the fluid, and exhausts the heated fluid through an outlet port.

According to one embodiment of the invention, a cooling system for a heat-generating structure includes a heating device, a cooling loop, and a separation structure. The heating device heats a flow of fluid coolant including a mixture of water and antifreeze. The cooling loop includes a director structure which directs the flow of the fluid coolant substantially in the form of a liquid to the heating device. The heating device vaporizes a substantial portion of the water into vapor while leaving a substantial portion of the antifreeze as liquid. The separation structure receives, from the heating device, the flow of fluid coolant with the substantial portion of the water as vapor and the substantial portion of the antifreeze as liquid. The separation structure separates one of the substantial portion of the water as vapor or the substantial portion of the antifreeze as liquid from the cooling loop while allowing the other of the substantial portion of the water as vapor or the substantial portion of the antifreeze as liquid to remain in the cooling loop.

A heat exchanger extracts heat from a two-phase fluid coolant so that the coolant changes from a vapor state to a liquid state. Two valves have respective inlets which communicate with the coolant in the heat exchanger, and which are physically spaced from each other. Valve control structure responds to the presence of liquid at the inlet to either valve by opening that valve, so that the liquid coolant flows through the valve to a discharge section. A different feature involves a housing with a heat exchanger therein, the heat exchanger having a plurality of coolant conduits that are axially spaced. A flow of air travels axially within the housing, then flows transversely past the conduits to the other side thereof, and then resumes flowing axially on the other side of the conduits.

According to an embodiment of the present invention, a thermal management system for electronic components includes a plastic coldplate having a mounting surface for mounting one or more electronic components, one or more passageways configured to have a fluid flow therethrough disposed within the plastic coldplate, and a highly conductive material disposed within the plastic coldplate and thermally coupled to the mounting surface. The highly conductive material is operable to transfer heat from the mounting surface to the fluid flow.

A vibratory seismic energy source capable of generating significant energy over a broad frequency band. The vibrating baseplate and associated structure are designed to have minimum weight while still retaining sufficient structural integrity to permit the use of high actuator forces. This, coupled with a large reaction mass results in the generation of significant energy levels in the earth at high frequencies.

In certain embodiments, removing non-condensable gas from a cooling system includes trapping contents of a discharge tube of a heat exchanger, where the heat exchanger is in thermal communication with an ambient environment at an ambient temperature. The contents of the discharge tube comprises a vapor portion of a cooling fluid, a liquid portion of the cooling fluid, and a non-condensable gas. The cooling fluid is at a subambient pressure, and the ambient temperature is lower than a boiling point of the cooling fluid. A first additional portion of the cooling fluid is inlet into the discharge tube to increase a pressure within the discharge tube. The vapor portion of the cooling fluid within the discharge tube is allowed to condense. A second additional portion of the cooling fluid is inlet to purge the non-condensable gas from the discharge tube.
摘要:
An apparatus includes heat-generating structure disposed in an environment having an ambient pressure, and a cooling system for removing heat from the heat-generating structure. The cooling system includes a fluid coolant, structure which reduces a pressure of the coolant to a subambient pressure at which the coolant has a boiling temperature less than a temperature of the heat-generating structure; and structure which directs a flow of the liquid coolant at the subambient pressure so that it is brought into thermal communication with the heat-generating structure, the coolant then absorbing heat and changing to a vapor.
