A heat exchange device of a floating core type, having a special configuration which allows increasing its durability as it increases its thermal fatigue resistance. The device is characterized by a configuration having high thermal fatigue resistance due to the special configuration of the end where the floating side of the core is located since stagnation regions that are usually produced in the baffle of the floating end are eliminated by the combination of the shape of the shell and of a deflector. This configuration furthermore results in a low-cost exchanger.

A heat exchanger is comprised of two heat exchanger sections, at least one of which is provided with a floating header to accommodate differential thermal expansion. The two heat exchanger sections are enclosed by an inner shell wall, and an external connecting passage is provided outside the inner shell wall, through which one of the fluids flows between the two heat exchanger sections. The external connecting passage is enclosed by an outer shell. The inner wall is provided with openings which communicate with the external connecting passage. The openings may be in the form of a substantially continuous gap or discrete openings. Specific examples of heat exchangers with this construction include a steam generator, a steam generator and combined catalytic converter, and a water gas shift reactor.

Provided is a heat-exchanging and mixing device and a solution transport and cooling unit which are capable of efficiently performing heat transfer with respect to a heat-exchange target, while stirring and mixing the heat-exchange target, to obtain an advantageous effect of being able to significantly hinder accumulation of a solid content in the solution transport and cooling unit. The heat-exchanging and mixing device comprises a heat exchanger tube and a spiral mixing member having a width approximately equal to an inner diameter of the heat exchanger tube and disposed inside the heat exchanger tube. The spiral mixing member is comprised of a strip-shaped member having an inter-slit region.

An apparatus and method of forming a heat exchanger including a thermally compliant material and geometry with a core having a first set of flow passages and a second set of flow passages passing through the core. A first manifold of high temperature and strength material defines a fluid inlet for the first set of flow passages and a second manifold of high temperature and strength material defines a fluid inlet for the second set of flow passages. At least one of the first and second manifolds can include an in-situ compliant portion to provide for compliance during thermal expansion of the heat exchanger.

An intercooler assembly may include a housing and a cooler arranged therein through which charge air may be flowable. The housing may include an insertion opening through which the cooler may be insertable into the housing in an insertion direction transverse to the flow direction of the charge air. The cooler may include a pipe structure through which a coolant may be flowable, first and second end parts opposite each other transverse to the insertion direction, and third and fourth end parts opposite each other transverse to the first and second end parts and parallel to the flow direction, the end parts laterally delimiting and mechanically connected to the pipe structure. The cooler may be mechanically connected to the housing by the first end part, and at least one of the other end parts may be movably attached to the housing. The cooler may be pre-stressed against the housing by the third and/or fourth end part in a direction opposite a deformation of the cooler resulting from cooling of the charge air.

A heat exchanger having a core including a plurality of parallel layered flow passages for accommodating a first fluid flow, and a plurality of layered cross-flow passages in thermal communication with the layered flow passages for accommodating a second fluid flow, an inlet manifold associated with an inlet side of the core and including an inlet for the first fluid flow, a manifold wall having a bellows-type construction to accommodate expansion and an interface with the core that includes an array of flow ports in communication with the layered flow passages of the core, and an outlet manifold associated with an outlet side of the core and including an outlet for the first fluid flow, a manifold wall having a bellows-type construction to accommodate expansion and an interface with the core that includes an array of flow ports in communication with the layered flow passages of the core.

A liquid immersion bath includes: a liquid immersion bath main body in which liquid coolant and an electronic device to be immersed in the coolant are placed; a coolant inlet and a coolant outlet provided to the liquid immersion bath main body; a coolant discharge port which floats on a liquid surface of the liquid coolant in the liquid immersion bath main body; and a hose which couples the coolant outlet and the coolant discharge port and bends in accordance with a movement of the coolant discharge port due to variation in a height of the liquid surface.

A cooling assembly for an electromechanical cylinder has a rotary union unit with a coolant interface and at least one mounting point for mounting the rotary union unit to the electromechanical cylinder having a hollow screw shaft. Further, a hollow tube is fastened to the rotary union unit in a torque-proof manner, the hollow tube being in fluid communication with a first port of the coolant interface. The at least one mounting point is configured such that upon mounting the rotary union unit to the electromechanical cylinder, the hollow tube protrudes into a cavity of the hollow screw shaft and the cavity is in fluid communication with a second port of the coolant interface such that an inflow channel and a backflow channel are formed within the hollow screw shaft.

A plant or refinery may include equipment such as reactors, heaters, heat exchangers, regenerators, separators, or the like. Types of heat exchangers include shell and tube, plate, plate and shell, plate fin, air cooled, wetted-surface air cooled, or the like. Operating methods may impact deterioration in equipment condition, prolong equipment life, extend production operating time, or provide other benefits. Mechanical or digital sensors may be used for monitoring equipment, and sensor data may be programmatically analyzed to identify developing problems. For example, sensors may be used in conjunction with one or more system components to detect and correct maldistribution, cross-leakage, strain, pre-leakage, thermal stresses, fouling, vibration, problems in liquid lifting, conditions that can affect air-cooled exchangers, conditions that can affect a wetted-surface air-cooled heat exchanger, or the like. An operating condition or mode may be adjusted to prolong equipment life or avoid equipment failure.
