Material Cooling Means Including Gas-liquid Contactor Patents (Class 62/304)
  • Patent number: 11029063
    Abstract: A compressor system is disclosed having a refrigerated dryer useful to remove moisture from a wet compressed flow stream produced by a compressor. The refrigerated dryer can include a condenser having a refrigerant fluid conduit and a number of external cooling fins which assist in cooling the refrigerant fluid upon passage of a cooling flow stream past the external cooling fins. The compressor system can include an offtake passage to extract a portion of the wet compressed gas. The extracted portion of compressed gas can be blown in a direction transverse to (e.g. opposite) the direction of cooling air provided by the fan. In one form the fan can be deactivated when the extracted compressed air is flowed past the cooling fins. The compressor system can include a manual operation, operation dictated by a timer, or operations based upon sensed/estimated/etc pressures or temperatures of the compressor system.

  • Patent number: 9016201
    Abstract: Apparatus and method for applying a water-based emulsion of silicone fluid to a printed web required to be cooled, such that evaporative cooling of the web is promoted in addition to coating of said web with a silicone material. Water evaporated following the application of the silicone fluid to the web is recovered by condensation on the applicator(s) and reapplied to the web, thus economizing the amount of silicone fluid mixture necessary to provide both cooling and enhanced slip characteristics necessary for further handling and processing of the web. The condensation step is effected by containing the evaporated water from the web within a compact enclosure enveloping both the applicator(s) and the web, and optionally chilling said applicator(s) with a cooling medium, preferably water, by means of said cooling medium flowing through at least one of the applicators.

  • Patent number: 8820113
    Abstract: To reduce power consumption and more efficiently cool computing devices in a data center, an air supply unit supplies air from outside the data center to an air handling unit, which cools servers within the data center using the supplied air. Using air from outside the data center, rather than recirculating and cooling air from within the data center, reduces the power consumption of the data center. In an embodiment, a chiller and/or an evaporative cooling system are coupled to the air supply unit to allow further cooling of the outside air before it is circulated. Heat generated by the servers within the data center is collected, for example using thermal pathways coupled to server components, and used by the chiller in an absorption or adsorption process to further reduce power consumption of the data center and allow the air handling unit to further cool the outside air.

  • Patent number: 8635878
    Abstract: Chilled water is produced by an evaporative cooling process. The chilled water is then circulated through a liquid-air heat exchanger to produce a primary air supply of cool-dry air wherein no water is introduced into the cool dry air stream. The primary air supply can be used to cool a space, such as an office, where low humidly is desirable. Additionally, the cool, wet air which is a byproduct of the water-cooling phase can be used as a secondary air supply. The secondary air supply can be used to cool a space where higher humidity is tolerated, such as a warehouse, a garage, a barn, etc. The indirect evaporative cooling system can also be used in conjunction with an air conditioning system to reduce operating costs and increase efficiency.

    Abstract: Systems and methods provide a mist cooling system that utilizes rain water as a source of mist, and that relies on a solar-powered or naturally-powered water pump to provide the rainwater to the mist generating device. The rainwater may be stored in a storage facility located on an elevated portion of a structure, such as the roof or other location, and may be provided to the mist generating device via the solar-powered pump. Such mist cooling may reduce energy consumption in applications such as the cooling of data centers, surgery rooms, archives or other temperature sensitive facilities that consume large amounts of energy for cooling.

  • Patent number: 8561675
    Abstract: A spray type heat-exchanging unit includes a main body; a distributive refrigerant spray module located in an upper part of the main body and having an extended distributor and a refrigerant spray surface; and a plurality of heat exchange tubes provided in the main body below the distributive refrigerant spray module. A liquid refrigerant is guided into the extended distributor to drip onto the refrigerant spray surface, and then uniformly sprayed onto the heat exchange tubes. Gaseous refrigerant produced by evaporation in heat exchange in the main body is recovered via a top opening of the main body, making the mechanical refrigerating apparatus more efficient than a refrigerating apparatus adopting a flooded evaporator, and minimizing the refrigerant charge amount and material cost required by the heat-exchanging unit.

    Abstract: A cooling system can control a coolant temperature with a simple configuration. The cooling system 90 includes a vaporization vessel 80, a first fluid source 92, a first flow rate control unit 91, and a pressure control unit 99. The vaporization vessel 80 has a space, a supply opening 80a and a discharge opening 80b through which the coolant is supplied and discharged, respectively. The first fluid source 92 stores a first fluid having a vapor pressure higher than that of the coolant. The first flow rate control unit 91 connects the first fluid source 92 to the vaporization vessel 80 and controls a first fluid supply amount into the vaporization vessel. The pressure control unit 99 controls an internal pressure within the vaporization vessel to be higher than the vapor pressure of the coolant and equal to or lower than that of the first fluid.

    Abstract: Dissipating heat and apparatus therefor from a heat dissipation surface is described. In an embodiment, first jets are streamed along the heat dissipation surface in a first direction and are spaced apart from one another. Second jets are streamed along the heat dissipation surface in a second direction at least substantially opposite the first direction and spaced apart from one another. Coolant used to provide the first jets and the second jets is exited away from the heat dissipation surface. The first jets and the second jets are offset from one another in a transverse direction with respect to the first direction and the second direction, and the first jets and the second jets pass side-by-side with respect to one another.

  • Patent number: 8468846
    Abstract: Systems and methods for Indirect Evaporative Cooling and for Two Stage Evaporative Cooling for conditioning fluids such as air are disclosed. The Indirect Evaporative Cooling Systems comprise scalable indirect evaporative heat exchangers formed with polymer substrates that have been treated to render one surface substantially hydrophilic while the other is substantially hydrophobic, with channels for passage of primary (cooled) an secondary (cooling) air streams between them. The Two Stage Evaporative Cooling System comprise an indirect evaporation component where the fluid is pre-cooled indirectly with the abovementioned scalable heat exchangers, followed by a direct evaporation stage where the pre-cooled fluid is further cooled directly by adiabatic evaporative cooling. The device employing these systems is scalable, energy-efficient, uses aseptic materials, filters/clean incoming fluids (e.g. air), circulates disinfected evaporating liquid (e.g. disinfected water and has enhanced performance efficiency.

  • Publication number: 20130133346
    Abstract: The invention is directed toward a vapor-liquid heat and/or mass exchange device that can be used in an integrated heat and/or mass transfer system. To achieve high heat and mass transfer rates, optimal temperature profiles, size reduction and performance increases, appropriately sized flow passages with microscale features, and countercurrent flow configurations between working fluid solution, vapor stream, and/or the coupling fluid in one or more functional sections of the desorber are implemented. In one exemplary embodiment of the present invention, a desorber section utilizes a heating fluid flowing in a generally upward direction and a concentrated solution flowing in a generally downward direction with gravity countercurrent to the rising desorbed vapor stream. To further increase the efficiency of the system, various types of column configurations can be used. Additionally, the surfaces of the microchannels can be altered to better transfer heat.
