Abstract: A method is provided for manufacturing a bundle of plates for a heat exchanger made up of a stack of plates. The method includes reducing by machining the initial thickness of each plate by making at least at the periphery of the plate, at least one connecting shoe having a height greater than the thickness of the machined plate, forming on the central portion of the plate, corrugations, to be superposed pairwise on the plates, connecting the shoes in contact with the plates of each pair through a weld bead, superposing the pairs of plates and connecting the shoes in contact with the pairs of plates through a sealed weld bead by arranging a superposition of open or closed ends for alternate inflow or outflow of said fluid.

Abstract: A heat exchanger, includes modules defining a first path for a first fluid, each having two metal sheets forming between them a network of channels which are located in parallel with each other from the fluidic point of view, each channel interposed between two neighbouring channels of the network being, over the whole of its developed length, adjacent to these two neighbouring channels from which it is isolated by two respective weld lines connecting the two metal sheets; a second path for a second fluid is defined between the modules; and an overall variation in the passage cross-section over the length of at least one of the paths with continuity of profiles of the channels.

Abstract: The invention relates to an installation for exchanging heat between fluids, the installation being of the type comprising a leaktight enclosure, means for exchanging heat between the fluids, and fluid admission and discharge means. The heat exchanger means comprise bundles of plates formed by stacks of horizontal plates and distributed in a star configuration around a tubular central collector concentric with the enclosure. Each bundle of plates has a front vertical wall secured to the collector and a rear vertical wall that is free, and each is slidably supported on a support member secured to the enclosure.

Abstract: The heat exchanger plate presents first adjacent first corrugations generally directed along respective alignment axes in the longitudinal direction of the plate and comprising successive segments that are substantially rectilinear and oblique, being successively inclined in a first sense and in a second sense relative to the longitudinal axis. The heat exchanger plate also has at least one deformation zone constituted by at least one set of segments of second corrugations of generally transverse direction intersecting the set of longitudinal axes along which the first corrugations are disposed. The alignment axes of the segments of second corrugations make an angle lying in the range 45° to 90° with the longitudinal axes of the first corrugations.

Abstract: The invention relates to a plate heat exchanger (1) of the type comprising an impervious chamber (2), a bundle of plates (3) arranged in said chamber (2) and providing therewith a free space (4), an inlet pipe (10) for hot fluid in a first circuit of this bundle (3), an outlet pipe (12) for the cooled fluid, an inlet pipe (20) for a cold fluid communicating with the inlet of the second circuit of this bundle (3), and an outlet pipe (21) for the heated fluid. The heat exchanger also comprises means (25) for channelling the cold fluid along the internal wall of the chamber (2).

Abstract: A vane for a fan including a platform, a root and a blade. The platform has opposite outer and inner surfaces, and opposite upper and lower surfaces. The upper surface has a camber shape, and the lower surface has a concave shape corresponding to the camber shape of the upper surface. The root is fixed to the inner surface of the platform and adapted to be fixed to a hub of the fan. The blade is fixed to the outer surface of the platform at a position shifted toward the lower surface from a center line between the upper and lower surfaces.

Abstract: A packing member for restraining the root of a fan blade in a socket of a rotor disk takes the form of a curvilinear plate comprising a metallic sub-structure having recessed portions and a semi-rigid elastomeric material molded into and filling the recessed portions. The member has a substantially metallic central area extending as far as the side edge of the member on the same side as the extrados face of the blade, the metallic central area having a machined profile set back relative to the profile of the socket so as to permit the root of the blade to rock in response to a violent impact on the blade. The packing member has upstream and downstream end areas which are entirely metallic, and the two side edges of the member upstream and downstream of the central area are defined by the elastomeric material. Between the two elastomeric side edges, both upstream and downstream of the metallic central area, the member has a metallic lower part and an upper part formed by the elastomeric material.
