  • Patent number: 9587842
    Abstract: For minimizing the effect of wind on a heat exchanger system having a plurality of finned tube arrays and a plurality of fans, a method includes providing a wind louver below one of the fans. The wind louver is arranged to divert wind flowing in an approximately horizontal direction below the one of the plurality of fans to instead flow in a direction that is more vertically upward as compared to the approximately horizontal direction. Readings of a heat exchanger outlet temperature, ambient temperature, wind, and inlet air pressure are collected and recorded, and compared to previous readings. The louver height is changed if the readings have changed.

The first set of passageways and second set of passageways being separate and permitting the warm water laden air stream to be cooled by the stream of ambient air so that water can condense out of the warm water laden air stream. Cooling tower configurations including the heat exchanger pack are disclosed for achieving effluent plume abatement, and capture of a portion of the effluent for replacement back into the cooling tower reservoir or as a source of purified water.

  • Patent number: 6213200
    Abstract: A system and method of exchanging heat are disclosed. Three heat exchange sections are used: a dry indirect contact heat exchange section, a second indirect contact heat exchange section that is operable in either a wet or dry mode, and a direct contact heat exchange section. The three sections are next to each other in an apparatus to reduce the overall height of the apparatus. The dry and second indirect contact heat exchange sections receive a process fluid in series or in parallel. Separate ambient air streams pass through the second indirect and direct contact heat exchange sections before mixing and entering the dry indirect contact heat exchange section. Another ambient air stream is mixed in upstream of the dry indirect contact heat exchange section when the system is operated in the dry mode. Two independent evaporative liquid distribution systems are included. One selectively distributes evaporative liquid over the second indirect contact heat exchange section.

  • Patent number: 5724828
    Abstract: A heat exchange apparatus which can be used as an evaporative condenser, fluid cooler or wet-air cooler, is provided with a direct evaporative heat exchange section overlying an indirect evaporative heat exchange section. An air entry zone common to both heat exchange sections receives an air stream blown into this zone by at least one fan, thereby pressurizing the plenum such that the air stream is forced to split and enter each section while inside the apparatus. This eliminates the need for separate air entries, thus condensing the size and cost of the apparatus, while increasing heat exchange capacity. A countercurrent air flow pattern through the direct section provides a uniformly cooled evaporative liquid for use in the indirect section. The evaporative liquid flow is parallel to the air stream provided in the indirect section.

  • Patent number: 5692384
    Abstract: This invention uses an air to air heat exchanger to cool the air passing through an evaporative water cooler. This enables the evaporative water cooler to cool water to a temperature very near to the dewpoint temperature. The water so cooled may be used to remove heat from other media. One use of the cooled water is to remove heat from a habitation. This invention provides in hot arid climates a method of cooling air inside a habitation to a temperature providing comfort to the occupants at a much lower cost and at a much lower usage of electrical energy than previous methods.

  • Patent number: 5082055
    Abstract: An in situ thermal system is disclosed for enhanced oil recovery and the like from a subterranean formation. The system pressurizes the formation with water whereupon the entire formation is heated to relatively high temperatures in the absence of gas formation to significantly decrease the viscosity of substantially all the crude in the formation and permit recovery thereof. A down hole, fuel fired radiant tube burner of long length is provided to achieve the desired heat patterns within the formation. The burner includes three concentric, closed end tubes with the innermost tube containing a burner and spaced closely adjacent the intermediate tube. A hole pattern in the innermost and intermediate tube establishes a laminar flow of the burner's products of combustion therebetween which modifies the radiation heat flux pattern so that uniform heat is emitted from the outermost tube along its length.

  • Patent number: 4713943
    Abstract: An evaporative cooler air conditioning system comprising an air-to-air counter-flow heat exchanger having separate dry cooling and wet evaporating chambers, air saturating elements, and air movement devices. Ambient supply air or other fluid is forced through the dry cooling chamber of the heat exchanger and exits, after transferring through the heat exchanger, into the cooled spaced or room to be cooled. The air in the cooled space absorbs heat from the heat load and reaches an equilibrium at a warmer temperature, and is then forced directly through the wet evaporative chamber of the heat exchanger where it is heavily saturated with water or other liquid.

  • Patent number: 4267130
    Abstract: A portable auxiliary cooling tower which is transportable over-the-highway for temporary or permanent use at a desired site. The tower is typically constructed on a trailer frame and is designed to provide maximum air flow for maximum cooling to temporarily replace or supplement larger fixed cooling tower cells. Another use of the portable cooling tower is to aerate stock ponds, chemical holding ponds and the like.

  • Patent number: 4249391
    Abstract: Water vapor released by evaporation in a cooling tower, is conducted through an enclosure to the upper inlet end of a vertical conduit extending into the body of water stored in the cooling tower. The water vapor downflowing through the vertical conduit under vacuum conditions is condensed by cooling sprays of water drawn by pumps from the bottom of the cooling tower.

  • Patent number: 4108126
    Abstract: Disclosed is a fuel feed device of an internal combustion engine. The fuel supply conduit communicating the carburetor and the fuel tank is arranged in the carburetor for cooling the carburetor and for vaporizing the low boiling components in the fuel only when the temperature of the engine is higher than a predetermined level. The fuel flowing out from the fuel supply passage located in the carburetor is introduced into a low boiling component separator. In this separator, the low boiling components in the fuel are removed, and then the fuel consisting of the high boiling components is fed into the carburetor to prevent the occurrence of an abnormal fuel metering operation under a high-temperature condition.

  • Patent number: 4102650
    Abstract: A liquid feed and effluent system to recover dissolved process gas (e.g. H.sub.2 S) from an effluent process liquid (e.g. water), which liquid may also contain dissolved solid components (e.g. soluble salts); the system heats the feed liquid with heat recovered from the effluent liquid, saturates the so heated feed liquid with process gas, which gas may also contain inert gas components, and separately discharges from the system such inert gas components and effluent liquid from which process gas and heat have been recovered. In the combination the dissolved process gas is preferably recovered from the effluent liquid by flashing at progressively reduced pressures and final vapor stripping thereof at the most reduced pressure.
