  • Patent number: 11268698
    Abstract: A combustor includes an inner liner forming a combustion chamber; an outer liner surrounding the inner liner to form a cooling passage in which compressed air flows; and a plurality of cooling guides installed around an inner circumferential surface of the outer liner to surround the combustion chamber, each of the cooling guides protruding from the inner circumferential surface to create an impinging jet from the compressed air flowing in the cooling passage. The plurality of cooling guides surrounding the combustion chamber are installed at regular intervals in a flow direction of the compressed air, and are arranged in staggered axial rows. Each cooling guide includes an air guiding surface facing the flow of the compressed air to guide the compressed air toward the inner liner. Accordingly, liner cooling efficiency can be enhanced by more effectively guiding the impinging jet toward the inner liner.

  • Patent number: 8014150
    Abstract: Cooled electronic modules and methods of fabrication are provided with pump-enhanced, dielectric fluid immersion-cooling of the electronic device. The cooled electronic module includes a substrate supporting an electronic device to be cooled. A cooling apparatus couples to the substrate, and includes a housing configured to at least partially surround and form a sealed compartment about the electronic device. Additionally, the cooling apparatus includes dielectric fluid and one or more pumps disposed within the sealed compartment. The dielectric fluid is in direct contact with the electronic device, and the pump is an impingement-cooling, immersed pump disposed to actively pump dielectric fluid within the sealed compartment towards the electronic device. Multiple condenser fins extend from the housing into the sealed compartment in an upper portion of the sealed compartment, and a liquid-cooled cold plate or an air-cooled heat sink is coupled to the top of the housing for cooling the condenser fins.

  • Patent number: 7882889
    Abstract: A loop type heat dissipating apparatus with a sprayer for transferring heat between a heat source and a heat sink includes an evaporator, a condenser, and a working fluid. The evaporator contacts the heat source and includes a first chamber, a second chamber, and a sprayer disposed between therebetween. The condenser contacts the heat sink and includes a third chamber communicating with the second chamber and a wick structure disposed on one side of the third chamber. The working fluid fills the loop type heat dissipating apparatus and is turned into microdroplets via a sprayer. The sprayer impinges the microdroplets into the second chamber where the microdroplets are then evaporated by the heat source before proceeding to the third chamber for condensation, liquefaction and adhering to the wick structure. Eventually, the working fluid flows back to the first chamber under a pumping force actuated by the sprayer and completes the cycle.

  • Patent number: 7885074
    Abstract: Cooling apparatuses and methods are provided for facilitating cooling of an electronic device utilizing a cooling subassembly, a pump and a controller. The cooling subassembly includes a jet impingement structure, and a thermosyphon. The jet impingement structure directs coolant into a chamber of the subassembly onto a surface to be cooled when in a jet impingement mode, and the thermosyphon, which is associated with the chamber, facilitates convective cooling of the surface to be cooled via boiling of coolant within the chamber when in a thermosyphon mode. The controller, which is coupled to the pump to control activation and deactivation of the pump, also controls transitioning between the jet impingement mode and the thermosyphon mode based on a sensed temperature of the electronic device.

  • Patent number: 7821787
    Abstract: A system (50) for cooling a target element (56) includes a structure (52) having an opening (62) extending through the layer (52), a pumping device (32) positioned behind the structure (52), and a target element (56) positioned in front of the structure (52). Transducers (58, 60) are positioned at opposing ends (74, 76) of the opening (62) between the structure (52) and the target element (56). The pumping device (32) drives a jet (70) of coolant through the opening (62) toward the target element (56). The transducers (58, 60) produce output signals (84, 86) that perturb the jet (70) to control oscillation of the jet (70) in order to stabilize the jet (70) for impingement with a predetermined location (96) on the target element (56). The jet (70) uniformly spreads from the location (96) to provide cooling over a surface (100) of the target element (56).

  • Patent number: 7694528
    Abstract: In a heat exchanging apparatus for a vapor compression refrigerant cycle, an internal heat exchanger is attached to an end of a radiator. The internal heat exchanger is arranged such that high-pressure refrigerant passages are closer to the radiator than low-pressure refrigerant passages. The heat exchanging apparatus can be mounted on a vehicle such that the radiator receives cooling air more than the internal heat exchanger. Because the internal heat exchanger performs heat exchange between high-pressure refrigerant and low-pressure refrigerant, performance of the internal heat exchanger is not degraded even if it is located at a part receiving less cooling air. Thus, the heat exchanging apparatus is easily mounted on a vehicle by integrating the internal heat exchanger with the radiator, without reducing a cooling capacity of the radiator.
