摘要： A refrigeration system is provided, such as for use with chillers. The system uses a tube-side condenser, such as a microchannel condenser, along with a shell-side evaporator such as a falling film evaporator. A flash tank economizer is disposed between the condenser and the evaporator, and an inlet valve to the flash tank is controlled based upon subcooling of condensate from the condenser. The vapor exiting the flash tank may be fed via an economizer line to a system compressor. Liquid phase refrigerant combined with some gas phase refrigerant exits the flash tank and is directed through an orifice before entering the evaporator.

摘要： An evaporative HVAC apparatus is disclosed. In at least one embodiment, the apparatus provides an at least one housing having an inner surface that defines a substantially tubular-shaped air passage extending therethrough. An absorbent wicking layer is formed immediately adjacent to at least a portion of the inner surface of the housing, and a thermal layer is formed immediately adjacent to an inner surface of the wicking layer. The housing also provides an at least one fluid inlet aperture through which a fluid line extends a distance into the housing so as to be in fluid communication with the wicking layer. Thus, a fluid is selectively delivered to the wicking layer through the fluid line which, in turn, permeates the thermal layer and evaporates into the air located immediately adjacent an exposed inner surface of the thermal layer, thereby affecting the temperature of the air moving through the air passage.

摘要： The subject invention pertains to a spray nozzle apparatus and method of use. The subject spray nozzle can be used to spray atomized fluid. The atomized fluid can then be incident on a heated surface such that heat is transferred from the heated surface to the atomized fluid. The subject invention also relates to a spray-cooling system and method of use. The subject spray-cooling system can incorporate a spray nozzle and a heat transfer plate. A device to be cooled, such as a laser diode, microwave amplifier, or other high power electrical device, can be placed in direct thermal contact with the heat transfer plate. The spray from the spray nozzle can then be sprayed onto the heat transfer plate. In a specific embodiment, a cellular transfer plate can be used and the spray from the spray nozzle can be sprayed into a cellular cavity or compartment, within the heat transfer plate. Heat is transferred from the heat source to the sprayed liquid via the wall of the heat transfer plate. The heat transfer plate can be attached to the spray nozzle housing, such that as the sprayed liquid exits the spray nozzle housing, the sprayed liquid enters a cellular cavity of the cellular heat transfer plate. Removing the cellular heat transfer plate from the spray-cooling assembly can allow the apparatus to be used as a conventional spray nozzle.

摘要： Electrospray evaporative cooling (ESC). Means for effectuating thermal management using electrospray cooling are presented herein. An ESC may be implemented having one or more nozzles situated to spray droplets of a fluid towards a target. Because the fluid may be electrolytic, an electric field may be established between the one or more nozzles and the target can be operative to govern the direction, rate, etc. of the electrospraying between the one or more nozzles and the target. An additional shielding/field enhancement electrode may also be implemented between the one or more nozzles and the target. A droplet movement mechanism may be employed to transport droplets received at a first location of the target so that evaporation thereof may occur relatively more at a second location of the target. An ESC device may be implemented to effectuate thermal management of any of a variety of types of electronic devices.

摘要： A cooling system including a thermosyphon subsystem and a spray cooling subsystem, each being configured to evaporatively cool a component, and a controller configured to selectively operate the spray cooling subsystem based on the cooling requirements of the component. The controller controls a valve limiting the operation of the thermosyphon when the spray cooling system is active. The component is configured to run in a plurality of performance states including a low power state and a high power state. The spray cooling system operates when the component is in the high power state. The controller can order the component to operate in a lower power state if the cooling systems are inadequate to the cooling needs. The cooling needs are determined with a component temperature sensor, a vapor temperature sensor, a vapor pressure sensor, or a power usage sensor.

摘要： A heat exchanger of flooded type, having: a primary tube bundle, inside which a first “hot” operating fluid to be cooled down flows; a skirt, circumscribed to the primary tube bundle, which receives a second “cold” operation fluid which laps against the primary tube bundle in order to subtract heat to the first operating fluid, which second operating fluid flows inside the skirt along to a vertical longitudinal direction orthogonal to the development of the tubes of the primary tube bundle, and wherein the skirt has a prevalent development dimension (L) along the flow longitudinal direction of the second operating fluid; and nozzles for delivering the secondary operating fluid inside the skirt, wherein an alternative configuration is provided using only the second operating fluid flooding the skirt by entering from a side inlet, without the presence of the above-mentioned nozzles, and an additional configuration using only the nozzles but not such side inlet.

摘要： An evaporative cooler has a housing with evaporative media at air inlets. A blower draws air into the inlets and through the media and then out an air outlet from the housing. A water pump in a water reservoir pumps water onto the media so that evaporation of the water cools the air being output by the blower. A timer is connected to the water pump to switch between ON operation that pumps water to the media and an OFF state in which the pump is not operated. The pump is cycled during operation of the cooler.
