Embodiment Construction

[0049] definition

[0050] The term "ring" is understood to mean an element having a closed profile having a thickness and delimiting an internal space open on either side of the closed profile. Typically, the closed profile has a generally circular cross-section, but it may have a different cross-section, such as oval, oblong, etc.

[0051] The term "column" is understood to mean the shell of an exchanger into which fluid is injected for its cooling or its heating, and includes rings such as those defined in the present invention. Typically, the post is cylindrical.

[0052] The expression "column and tube exchanger" is understood to mean an exchanger in which at least two fluids exchange heat, one fluid circulating in a column and a second fluid circulating in a tube. The surface of the tube acts as a support for exchanging heat between the two fluids.

[0053] The expression ""U"-shaped rod" is understood to mean an assembled or folded or bent rod forming three branches,...

Abstract

The present invention relates to Exchange tube support and securing assembly for tube exchanger. Specifically, the present invention relates to the field of the tube supports in heat exchangers used to exchange heat energy from one fluid to another without mixing them and its subject is more particularly a support for an exchange tube bundle forming, in a cutting plane, a mesh, said support (400) comprising a ring (40), wherein the ring (40) comprises fastening means making it possible to fasten, respectively, on either side of the cutting plane of the ring, a first set (41) of rods (410) and a second set (42) of rods (420), said rods (410, 420) each having a form which constitutes a median plane, the median planes of the first set (41) being parallel to one another and the median planes of the second set (42) being parallel to one another, the orientation of the median planes of the first set (41) and of the median planes of the second set (42) forming a first angle greater than zero.

Description

technical field [0001] This invention relates to the field of heat exchangers for exchanging thermal energy from one fluid to another without mixing them. The invention relates more particularly to tubular large-scale exchangers comprising supports making it possible to support tube bundles intended to transport fluids. The field of the invention relates more particularly to that of supports, such as rings, comprising elements making it possible to fix the tubes of tube exchangers. Background technique [0002] There are various types of exchangers used in industry, each of which fulfills specific needs depending on the desired heat transfer mode or the use of specific fluids. There are plate, coil, block, fin and even tube exchangers. Other switches exist in the prior art. [0003] Tube exchangers are particularly popular for their resistance to high pressures, adaptability to different power levels and wide temperature deviations. The exchanger offers the advantages of...
