20130174659 | SPEED SENSOR MODULE - An insert cover for a speed sensor module includes an elongated body having a length aligned along a longitudinal axis, the elongated body including a convex top surface and a uniform width along the length; a first portion emanating from the top surface at a first end of the elongated body; a second portion emanating from the top surface at a diametrically opposed second end of the elongated body; and a third portion emanating from the top surface between the first portion and the second portion; where each of the first, second, and third portions are orthogonal to the longitudinal axis. | 07-11-2013 |
20130177399 | SPEED SENSOR MODULE AND DIFFUSER ASSEMBLY - An environmental control system, includes an air cycle machine for conditioning an interior space with cooling air, the air cycle machine including a fan coupled to a shaft that rotates about a shaft axis, the fan being located at a distal end of the air cycle machine; a speed sensor module having a speed sensor for sensing a rotational speed of the shaft; wherein the speed sensor module includes an outer portion having a first bore aligned on the shaft axis, an intermediate portion having a second bore aligned on the shaft axis, and an inner portion aligned on the shaft axis; and a diffuser assembly including a cylindrical assembly for ducting a first portion of the cooling air to an inlet side of the fan and for communicating a second portion of the cooling air directly to a discharge side of the fan without passing the inlet side. | 07-11-2013 |
20140293540 | Heat Exchanger for Aircraft Application - A heat exchanger includes a plurality of mini-channel tubes. The mini-channel tubes extends for an axial length defined between two manifolds. The mini-channel tubes include a plurality of generally rectangular flow passages. The generally rectangular flow passages are aligned adjacent to each other to define a lateral dimension. A first lateral width of the generally rectangular passages is defined with a ratio of the axial length to the first lateral width being between 201.3 and 215.3. An aircraft system is also disclosed. | 10-02-2014 |
20140299303 | COOLING TUBE INCLUDED IN AIRCRAFT HEAT EXCHANGER - A channel tube includes a body having first and second surfaces extending between first and second opposing ends to define a tube width. The first and second surfaces are separated from each other by a distance defining a tube height. A plurality of ports extend through the body and between the first and second surfaces to define a fluid path extending in a direction of the tube width. Each port defines a plurality of walls and a plurality of ribs having a thermal conductive surface to transfer heat therethrough. A first wall extends in a direction of the tube width. The second wall extends in a direction of the tube width and is disposed opposite the first wall. At least one rib is integrally formed between the first and second walls and extends perpendicular thereto. | 10-09-2014 |
20140318175 | INTEGRAL HEAT EXCHANGER DISTRIBUTOR - A heat exchanger comprises a first inlet port, a first outlet port longitudinally spaced apart from the first inlet port, a plurality of substantially parallel parting plates stacked along a no-flow axis, a plurality of first flow spaces, and a plurality of metering plates. The plurality of first flow spaces are defined between adjacent ones of at least some of the parting plates and provide communication between the first inlet port and the first outlet port. The plurality of metering plates are disposed across an upstream end of at least one of the first flow spaces. Each of the plurality of metering plates includes at least one metering aperture providing fluid communication between the first inlet port and the at least one first flow space. | 10-30-2014 |
20150041105 | REDUCED THERMAL EXPANSION CLOSURE BARS FOR A HEAT EXCHANGER - A plate fin heat exchanger is configured to receive hot flow from a hot source and cool flow from a cool source. The plate fin heat exchanger includes a plurality of plates arranged in parallel to define a plurality of flow passages there between, and a set of closure bars arranged at a first side of the plurality of plates to seal a first set of the flow passages against ingress of the hot flow, thereby directing the hot flow into a second set of the flow passages. Each respective closure bar includes an inner core formed of a first material having a first coefficient of thermal expansion and an outer cladding arranged about the inner core, the outer cladding formed of a second material having a second coefficient of thermal expansion. The first coefficient of thermal expansion is less than the second coefficient of thermal expansion. | 02-12-2015 |
20150041109 | HEAT EXCHANGER THERMAL FATIGUE STRESS REDUCTION - A plate fin heat exchanger includes a plate fin core having a plurality of plates defining a set of hot air passages extending from a hot air inlet region of the plate fin core to a hot air outlet region of the plate fin core and a set of cool air passages extending from a cool air inlet region of the plate fin core to a cool air outlet region of the plate fin core. The plate fin heat exchanger further includes a mounting flange circumscribing the cool air outlet region. At least a portion of the mounting flange has a plurality of heat transfer structures that extend into a flow path of cooling air exiting the cool air outlet region of the plate fin core. | 02-12-2015 |
20150053380 | HEAT EXCHANGER FIN WITH CRACK ARRESTOR - A method of extending the lifetime of brazed primary hot inlet wavy fin structures of aircraft heat exchangers includes inserting slots in the fins. The slots increase the mechanical compliance of the fins as well as act as crack arrestors should a thermally induced fracture occur. In an embodiment, the slots are inserted by EDM. | 02-26-2015 |
