Housing is developed with a first connecting fitting and a second connecting fitting for each fluid. Heat transfer element is disposed in a volume completely enclosed in a housing and is developed for through-conduction of the first fluid. Housing is developed for conduction of the second fluid about the heat transfer element. Connecting fittings for second fluid are either disposed on the first housing element and the connecting fittings for the first fluid are disposed on the second housing element, wherein within the second housing at least one flow path for conducting the first fluid is implemented which extends between a connecting fitting and a collector region or the connecting fittings for the fluids are disposed on the first housing element.

摘要： A system and method for cooling an oxygen stream by heat exchange with a warming supply nitrogen stream having of a heat exchanger having at least a Zone A and a Zone B, the system having indirect heat exchange between a gaseous oxygen stream, and a high-pressure liquid nitrogen stream split into at least a first portion which passes through a Zone A, and a second portion which passes through a Zone B during a first phase of operation. And a high-pressure liquid nitrogen stream passing through Zone A, thereby producing a high-pressure nitrogen vapor stream, which passes through an expansion turbine, thereby producing an expansion turbine outlet stream which then passes through Zone B, during a second phase of operation, thereby producing a liquid oxygen stream.

摘要： A flow reactor is structured to increase the overall heat transfer coefficient, which represents the efficiency of heat exchange with respect to a reactive fluid to be treated. This flow reactor is provided with three flow passages, which are a first flow passage, a second flow passage, and a third flow passage which spirally circulate within a space formed between an inner tube and an outer tube. The flow passages are compartmented by an inner heat transfer body and an outer heat transfer bodies. The heat transfer bodies spirally circulate, have a screw-like cross-sectional shape in an axial cross-sectional view, and are assembled in a screw-like configuration. By changing the shapes of a male-thread portion and a female-thread portion, the flow passage area of the first flow passage is changed, the second flow passage and the third flow passage are spirally formed, and heat exchange and reaction take place through the heat transfer bodies.

摘要： An axial flow baffle for a shell and tube heat exchanger includes a substantially planar body configured for transverse arrangement in a longitudinally elongated shell of the shell and tube heat exchanger, a plurality of axial flow tube apertures each comprising a central tube hole configured to receive a tube of the heat exchanger, and an array of peripheral primary flow holes circumferentially spaced apart around the tube hole. The primary flow holes each interrupt the central tube hole and formed a radially inward projecting tube support protrusions between the primary flow holes which engage a single tube. Each primary flow hole has a non-polygonal configuration, which may be semicircular in some embodiments. The primary flow holes create axial flow around the periphery of the tubes through the baffles. In another aspect, a hybrid cross-flow baffle includes a combination of axial flow tube apertures and circular tube support holes.

摘要： A heat exchanger system includes a core structure with an oil flow path configured to receive an oil flow. The heat exchanger system also includes a fuel flow path included in the core structure and configured to receive a fuel flow. The fuel flow path is coupled to the oil flow path to allow the fuel flow to receive heat from the oil flow in the oil flow path. Also, the heat exchanger system includes a supplemental airflow path defined at least partly by the core structure and configured to receive a supplemental airflow that receives heat from at least one of the oil flow and the fuel flow.
