A fin produced from thick sheet-metal and having a pattern reproduced in a general direction in accordance with a geometric pitch such that the ratio of the minimum thickness of the sheet-metal to the geometric pitch is greater than 0.2. The fin is obtained either by a hot-extrusion operation or by a material-removing machining operation.

Fin for a plate heat exchanger, methods for the manufacture of such a fin, and a heat exchanger comprising such a fin

A method of manufacture includes the steps of making perforations using a perforating tool in a flat product before it is bent; making bends using a bending tool in the perforated flat product; detecting the position of a perforation on the corrugation; and slaving the relative position of tools to the detected position.

Input/output chamber for a fluid, for part of a body (1) of an apparatus in which this fluid circulates, this part of the body including a face (3) for inlet or outlet of the said fluid, the chamber (6A) being intended to be connected with a leaktight joint to this face. At least part of the chamber consists of at least one spherical or ellipsoidal portion (20A) and of sectors of cones (22A) tangential to this spherical or ellipsoidal portion.

Fluid inlet/outlet chamber and corresponding fluid circulation apparatus

A fluid circulation apparatus comprises a body part (2) in the shape of a dihedron with, on a first face of the dihedron, at least one opening for input/output of this fluid covering over the opening in a leaktight way. The bulb projects with respect to the body part (2) beyond the edge (13) of the dihedron and is produced by combination of metal sheets, of cylindrical, spherical and/or ellipsoidal shape, welded to one another. The apparatus is applicable to the integration of phase separators with heat exchangers of the brazed-plate type or alternatively to the input/output of fluids in such exchangers.
