Provided is an apparatus for cooling a metal material, the apparatus comprising: a spray cooling unit for spraying a cooling medium onto the surface of a metal material; and a spray amount control unit which regulates the rate of passage of the cooling medium sprayed from the spray cooling unit onto the edge region of the metal material, and controls the spray amount of the cooling medium.

A nozzle apparatus includes a manifold defining a nozzle cavity within an interior, a fluid inlet passage, a fluid outlet passage, an air outlet passage, and an air inlet passage. A nozzle holder and a nozzle element are selectively pivotable within the nozzle cavity. In the nominal position, the nozzle element inlet is oriented toward the fluid passage inlet and the nozzle element outlet is oriented toward the fluid passage outlet such that the primary fluid flows through the fluid inlet passage and out of the nozzle outlet through the fluid outlet passage. In the cleaning position, the nozzle element inlet is oriented toward the air outlet passage and the nozzle element outlet is oriented toward the air inlet passage such that the flow of air is directed through the air inlet passage, and out of the air outlet passage to direct debris out through the air outlet passage.

Air distribution nozzles, aircraft that include air distribution nozzles, and/or methods of utilizing air distribution nozzles are disclosed herein. The air distribution nozzles include an elongate inlet chamber, an elongate outlet chamber, a tapered elongate slot, an inlet port into the elongate inlet chamber, and an elongate outlet port from the elongate outlet chamber. The elongate inlet chamber extends along an inlet chamber length. The elongate outlet chamber extends along the inlet chamber length. The tapered elongate slot extends between, and fluidly interconnects, the elongate inlet chamber and the elongate outlet chamber. The inlet port is configured to receive an inlet fluid flow along an inlet flow axis. The elongate outlet port is configured to discharge an outlet fluid flow along an outlet flow axis that is oriented at a skew angle relative to the inlet flow axis.

Embodiments for producing un-agglomerated, monodisperse droplets using a liquid sheet are provided. Nozzles with exit slit openings shape a spray liquid into a thin liquid sheet as the spray liquid exits from the slit opening. Stable multi-jet operation is achieved by including notches along the edge of the slit. The notches separate the liquid sheet into multiple jets to provide anchoring and stable multi jet operation. In some embodiments, the liquid sheet electrospray techniques and nozzles described herein provide high mass throughput and versatile multiplexing spray systems while reducing the engineering effort and high manufacturing cost

A fluid line system including at least one liquid supply line, at least one gas supply line and at least two elongated fluid conduits is provided. Of the at least two elongated fluid conduits, at least one fluid conduit is an outer fluid conduit which completely encloses another fluid conduit which is inner fluid conduit. The liquid supply line is connected to the outer fluid conduit so that a liquid fluid can flow between the inner and outer fluid conduits. The gas supply line is connected to the inner fluid conduit so that a gaseous fluid can flow in the inner fluid conduit. A method for injecting a fluid mixture through a nozzle supplied by the fluid system is also.

The inventive concept relates to a liquid dispensing nozzle and an apparatus for treating a substrate. The liquid dispensing nozzle includes a first fluid channel that is formed in the nozzle and through which a processing liquid flows and a second fluid channel in communication with the first fluid channel, the second fluid channel being connected to a dispensing end of the nozzle. The second fluid channel has a larger width than the first fluid channel, and a central axis of the first fluid channel and a central axis of the second fluid channel are connected with each other in a straight line.

An insert assembly for a foam generating device includes a first insert and a second insert with a channel defined therethrough. Inserts may be formed by two shell halves that are coupleable to one another to define the channel. A plurality of ribs extends along an interior surface of the channel. Pad structures defined by porous media are provided in the channel and gripped by the plurality of ribs. The pads receive cleaning solution passing through the channel and cause foam to be generated by breaking-up the cleaning solution and agitating. The ribs may be arranged horizontally relative to a longitudinal axis of the insert assembly and retain the pads within the device. Inserts may be arranged in series along a longitudinal axis of the foam generating device with the pad structures arranged within the channel.

A nozzle apparatus may comprise a nozzle body having a nozzle tip with a discharge port for spraying a treatment fluid onto a substrate; a nozzle moving member for moving the nozzle body relative to the substrate; a rotating member for rotating the nozzle body or the nozzle tip so that a treatment fluid is sprayed onto the substrate during rotation; and a control unit configured to control an operation of the nozzle moving member and the rotating member.

A sealing agent (25) sent from a nozzle tube (36) to a nozzle main body (37) is passed through a main body flow channel portion (37a), a connecting portion (37c), a first flow channel portion (37b), and plural second flow channel portions (37d), sent to a chamber (37e), and discharged from a nozzle port (37f) to the outside. Since the second flow channel portions (37d) are smaller than a downstream end of the first flow channel portion (37b), the sealing agent (25) in the first flow channel portion (37b) is vigorously sent to the chamber (37e), and discharged from the nozzle port (37f) to the outside. As a result, substantially the same quantity of the sealing agent (25) is discharged in the entire range of the chamber (37e).

A head of a blow gun includes an inlet and an outlet openings formed by a main channel. The main channel defines a first section with a first open end adjacent to the inlet opening and a second open end and a second section with a first open end adjacent to the second open end of the first section and a second open end adjacent to the outlet opening. The second section has a cross section including two opposite short sides and two opposite long sides. The outlet opening is delimited by the short sides and long sides and has a long width between the short sides and a short width between the long sides respectively. At least one side channel has a first open end allowing the outside air to flow therein and a second open end fluidly connected to the second section.
