摘要： A heat exchanger assembly (26) for an aircraft (1000) includes a housing (92), a heat exchanger (96), and a nozzle (152). The housing (92) includes an inner flow path wall (100), an outer flow path wall (102), an inner inflatable diaphragm (224), and an outer inflatable diaphragm (226). The inner flow path wall (100) and the outer flow path wall (102) form an air inlet (106) and an air outlet (108). The inner inflatable diaphragm (224) and the outer inflatable diaphragm (226) form a venturi channel (134) between the air inlet (106) and the air outlet (108). The heat exchanger (96) is disposed downstream of the venturi channel (134) within the air flow path (110). The nozzle (152) includes a nozzle housing (158) disposed within the air flow path (110). The nozzle housing (158) forms a nozzle inlet (176) and a nozzle outlet (178). The nozzle outlet (178) is disposed at the venturi channel (134).

摘要： The invention relates to a mixer-heat exchanger insert or a mixer-heat exchanger insert assembly and to a mixer-heat exchanger comprising a corresponding mixer-heat exchanger insert assembly which has an improved mixing and temperature control behavior and which is less prone to fouling. The mixer-heat exchanger insert comprises a first group of hollow body plates (10, 11) with an inner volume (13) and a second group of hollow body plates (20, 21) with an inner volume (23). The hollow body plates (10, 11) of the first group are inclined in a first direction (RI) relative to a longitudinal extension direction (L) of the mixer-heat exchanger insert (1), and the hollow body plates (20, 21) of the second group are inclined in a second direction (R2) relative to the longitudinal extension direction (L) of the mixer-heat exchanger insert (1). The hollow body plates (10, 11) of the first group laterally abut the hollow body plates (20, 21) of the second group, and the inner volumes (13) of the first hollow body plates (10, 11) are connected to the inner volumes (23) of the second hollow body plates (20, 21) such that the inner volumes (13) of the first group and the inner volumes (23) of the second group are part of a continuous total inner volume (13, 23) which is designed to conduct a temperature controlling fluid.

摘要： A combustor for a liquid propellent motor has an elongated hollow tubular casing having an inner wall delimiting a combustion chamber for the liquid propellent and an outlet nozzle for the combustion products, and an outer wall, both being coaxial to an axis of the casing; the inner and outer walls being spaced apart from each other in radial direction and delimiting at least one guiding conduit of a cooling fluid therebetween; a plurality of bar-shaped elements extending into the guiding conduit, which form a grid for perturbing the cooling fluid, stiffening the casing and increasing the heat exchange surface; the grid being part of a body made in one piece and of a single material along with the inner and outer walls.

摘要： The invention provides a fin-and-tube heat exchanger using a return bend tube that allows further enhancement of the evaporative performance of the heat exchanger. The fin-and-tube heat exchanger, where a refrigerant is supplied inside tubing, has a hairpin tube portion where a plurality of hairpin tubes are arranged, a return bend tube portion where there are arranged a plurality of return bend tubes joined to respective hairpin tube ends of the hairpin tube portion, and a fin portion comprising a plurality of fins arranged at a predetermined spacing on the outer surface of the hairpin tubes. The heat exchanger comprises first grooves formed on the tube inner surface of the return bend tube. A first groove pitch (P1) of the first grooves in a cross section perpendicular to a tube axis, and a second groove pitch (P2) of spiral-shaped second grooves formed on the inner surface of the hairpin tube in a cross section perpendicular to a tube axis, satisfy a groove pitch ratio (P1/P2) of 0.65 to 2.2, while a first groove cross-sectional area (S1) per groove of the first grooves in a cross section perpendicular to the tube axis, and a second groove cross-sectional area (S2) per groove of the second grooves in a cross section perpendicular to the tube axis satisfy a groove cross-sectional area ratio (S1/S2) of 0.3 to 3.6.

摘要： A heat exchanger includes: a heat transfer pipe (232) in which refrigerant flows; and a spiral groove (235) formed at an inner peripheral surface of the heat transfer pipe. A height of an inner wall of the groove in a radial direction of the heat transfer pipe is equal to or greater than 0.1 [mm], and when a wetted edge length of the heat transfer pipe is S, an inclination angle between a pipe axis direction of the heat transfer pipe and a longitudinal direction of the groove in a section of the heat transfer pipe parallel with the pipe axis direction is θ, and a length of the heat transfer pipe is L, the inclination angle θ is an acute angle, and a wetted area S × L/cosθ of the heat transfer pipe satisfies S × L/cosθ ≥ 0.5 [m2].
