A spray nozzle configured to atomize and spray liquid by gas. The spray nozzle includes a liquid dripping prevention mechanism configured to prevent dripping of the liquid from the spray nozzle caused as a result of electrically charged fine particles of the liquid sprayed from the spray nozzle being attracted to and adhering to the spray nozzle.

A device for cooling a substance stored within the device has a body with an internal compartment for holding the substance to be cooled. The compartment can be sealed closed and can be accessed for adding substance to the compartment for cooling or for removing substance from the compartment after cooling the substance. The body of the device has an internal cavity that surrounds the exterior of the compartment holding the substance to be cooled. Fluidized coolant is injected into the cavity through an injection port to cool the substance contained within the compartment before removing the substance from the compartment for use. The device may include exterior buttons that compress the internal compartment when the buttons are pressed toward each other, which in turn compresses and breaks up the substance contained within the compartment.

A sublimator control valve system may comprise a sublimator having an injection port, a feedwater supply, a first solenoid valve in fluid communication with the feedwater supply and the injection port of the sublimator, a first sensor in electronic communication with a first controller, the first sensor configured to measure at least one of a first pressure parameter or a first temperature parameter; and a first tangible, non-transitory memory configured to communicate with the first controller, the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the first controller, cause the first controller to perform operations comprising receiving, by the first controller, a command signal and the first pressure parameter, and controlling, by the first controller, the first solenoid valve in response to at least one of the command signal or the first pressure parameter.

An apparatus includes a heat sink configured to receive thermal energy from one or more heat sources. The heat sink includes a local reservoir configured to hold a liquid coolant, and the heat sink is configured to pass the thermal energy into the liquid coolant in the local reservoir in order to vaporize at least some of the liquid coolant. The apparatus also includes a membrane configured to allow vaporized coolant to pass through the membrane out of the local reservoir into an ambient environment and to prevent unvaporized coolant from passing through the membrane. The membrane is thereby configured to provide passive flow control for the liquid coolant. The membrane could include a vapor-permeable and liquid-repelling membrane. The membrane can also be configured to hold the liquid coolant in the local reservoir against one or more surfaces of the heat sink.

The present invention relates to a wet evaporation-based cold concentration system, which is mainly applied to the technical field of air conditioners, and particularly applied to the technical field of heat-source tower heat-pump air conditioners. By utilizing a wet evaporation theory, a low-temperature low-concentration anti-freezing solution is enabled to contact low-temperature air in a wet evaporator to perform the heat and mass transfer, and water in the anti-freezing solution is vaporized at a low temperature into the air, thereby obtaining the high-concentration anti-freezing solution. By reasonably utilizing the concentration pool and the storage pool, the low-concentration anti-freezing solution is separated from the high-concentration anti-freezing solution, thereby achieving a purpose of simultaneously concentrating and storing the anti-freezing solution

A device includes a plurality of evaporators coupled to a payload bay with a multiplicity of coolant tubes in each evaporator, wherein each tube enters and then exits the payload bay, further comprising one or more cryogenic valves coupled to the coolant tubes; a pump to force coolant flowing through the evaporators; and a thermal box immediately outside the evaporators and payload bay to thermally seal the payload bay from the outside environment and reduce heat gain, the thermal box including high strength open cell panels and a vacuum or Vacuum Insulated Panels (VIPs) with polyurethane foam to fill the voids.

A water recirculation system operates in a primary mode for evaporatively cooling air. When the water recirculation mode malfunctions, the controller switches a secondary once-through mode. The system includes a sump for collecting water run-off from the evaporative pads, and a pump in fluid communication with the sump. The pump transfers moisture from the sump to the distribution arrangement located at the top of the evaporative pads during the recirculation mode. An automatically operated make-up water valve delivers water to a distribution arrangement on the evaporative pads. A moisture distribution arrangement distributes moisture to the evaporative pads and an automatically operated sump drain valve retains water in the sump when closed and freely drains water from the sump when open. A water level control communicates the sump water level to a control system. A monitoring mechanism detects whether the water-recirculation system has malfunctioned or is operating correctly.

An adiabatic cooling system includes a condenser coil and at least one mist chamber positioned around the condenser coil such that at least a portion of intake air for the adiabatic cooling system passes through the mist chamber prior to contacting the condenser coil. The at least one mist chamber includes a first cooling pad with a first intake-side face and a first output-side face and a second cooling pad with a first intake-side face and a first output-side face. The second-intake side face of the second cooling pad faces the first output-side face of the first cooling pad and is separated from the first-output side face of the first cooling pad by a gap. The gap includes a mist of water.
