A submersible heat-exchanging apparatus for installation into storage tanks used for containing industrial oils. The apparatus comprises a cylindrical heat-exchange component with one end sealingly engaging a terminal plug and the other end sealingly engaging and communicating with a coupling manifold having opposed inflow and outflow ports. A flow-directing elongate insert is provided with one end configured to engage the coupling manifold interposed the inflow and outflow ports, and the other end provided with an aperture and configured for abutting the terminal plug. The flow-directing elongate insert slidingly contacts and cooperates with the inner walls of the heat-conductive conduit thereby partitioning the heat-conductive conduit into two opposed fluid transmission channels wherein one channel communicates with the inlet port and the other channel communicates with the outlet port. The coupling manifold sealingly engages an aperture provided in the storage tank whereby the heat-exchange component extends into the tank.

The HEX arrangement may further include a plurality of supporting links coupled between the heat exchanger and the gas turbine engine for securing the heat exchanger relative to the gas turbine engine. The supporting links may comprise a statically determined system. A spring rate ratio of between 1% and 30% may exist between the plurality of ducts and the plurality of supporting links.

A heat exchanger has an intake header, a discharge header, a bundle of tubes extending in parallel between the intake header and the discharge header, an intake pipe connected to the intake header and extending transversely to the axes of the tubes of the bundle, the intake pipe having a first end opening into the header and a second end connectable to a process fluid supply pipe, and a baffle assembly for modifying the direction and rate of flow of the process fluid through the intake header, the baffle assembly being located within the intake pipe and secured to the intake pipe at a position adjacent the second end of the intake pipe. The baffle assembly comprises a plurality of slats lying in planes generally parallel to one another and inclined to the direction of fluid flow, and runners connected to the ends thereof to form a rigid structure.

A heat exchanger with a heat-exchange core in which a first fluid and a second fluid circulate, at least one header tank configured to duct the second fluid from or to the heat-exchange core. The header tank has at least a shoulder oriented toward the outside of said header tank, and at least one header tank corner. At least one fastening member for fastening the header tank is positioned at least partly at the periphery of the heat-exchange core and includes at least one peripheral groove delimited by a base wall and a lateral wall and in which the shoulder of the header tank is at least partially housed. Part of the corner portion faces an upper face of the shoulder opposite to the groove of the fastening member and at a non-zero distance from this upper face so that a space is left between the corner portion and the upper face of the shoulder.

A fluid flow-path device facilitates a maintenance operation to remove a foreign substance adhered to a member, to prevent passage of the foreign material. The fluid flow-path device has a distribution header including a partition member and a header body in a flow-path formation body. The partition member partitions a distribution space of the distribution header into an upstream-side space that communicates with a supply opening in the header body, and a downstream-side space that communicates with a plurality of flow paths in the flow-path formation body. The partition member includes a region that prevents a foreign substance in a fluid from flowing from the upstream-side space to the downstream-side space, while allowing the fluid to flow. The header body has an opening that allows a washing fluid to flow into the downstream-side space, and an opening that allows the washing fluid to be discharged from the upstream-side space.

A heat exchanger header includes a primary fluid duct extending between a fluid port and a first branched region, a plurality of secondary fluid ducts fluidly connected to the primary fluid duct at the first branched region, wherein an overhang region is formed laterally between adjacent ones of the plurality of secondary fluid ducts, and wherein each of the plurality of secondary fluid ducts extends between the first branched region and a second branched region, a plurality of tertiary fluid ducts fluidly connected to each of the plurality of secondary fluid ducts at the second branched regions, a primary horn integrally formed with and extending from the overhang region, an at least one secondary horn integrally formed with and extending from one of the plurality of tertiary fluid ducts, and a sacrificial support structure extending between the primary horn and the at least one secondary horn.

A flow path member for a heat exchanger includes: an inner cylinder capable of housing a heat recovery member through which a first fluid can flow; an outer cylinder having a feed port capable of feeding a second fluid and a discharge port capable of discharging the second fluid, the outer cylinder being disposed so as to be spaced on a radially outer side of the inner cylinder such that a flow path for the second fluid is formed between the outer cylinder and the inner cylinder; a feed pipe connected to the feed port; and a discharge pipe connected to the discharge port. The feed port and the discharge port are provided so as to be located in a distance of less than half the circumference of the outer cylinder in a circumferential direction.

A method for at least partially removing a contamination layer (24) from an optical surface (14a) of an optical element (14) that reflects EUV radiation includes: performing an atomic layer etching process for at least partially removing the contamination layer (24) from the optical surface (14a), which, in turn, includes: exposing the contamination layer (24) to a surface-modifying reactant (44) in a surface modification step, and exposing the contamination layer (24) to a material-detaching reactant (45) in a material detachment step. The optical element (14) is typically taken, before the atomic layer etching process is performed, from an optical arrangement, in particular from an EUV lithography system, in which the optical surface (14a) of the optical element (14) is exposed to EUV radiation (6), during which the contamination layer (24) is formed.

Provided are an integrated connector and a heat exchanger including the same, which may prevent assembly defects and leaks of a heat exchanger because the connector may be manufactured with precise dimensions, and is easy to manufacture, by integrally forming the connector that connects and firmly couples a header tank and a gas-liquid separator so that a heat exchanger medium communicates in the heat exchanger such as a condenser, in which the integrated connector is formed by molding a first pipe portion inserted into a hole of the header tank, a first flange portion in surface contact with an outer surface of the header tank, a second pipe portion inserted into a hole of the gas-liquid separator, and a second flange portion in surface contact with an outer surface of the gas-liquid separator so as to be connected to one another and have an interior communicating with one another.
