Embodiment Construction

[0060] specific reference Figures 11A to 15 , shows some preferred embodiments of a heat exchanger with a tube bundle and a shell according to the present invention, indicated generally at 10 . The heat exchanger 10 comprises, in a manner known per se, a plurality of tubes 12 arranged parallel to one another to form one or more tube bundles. The tube 12 is inserted axially into a member 14 of elongate form, which has a cylindrical geometry and constitutes the housing of the heat exchanger 10 . In this specification, the term "member with cylindrical geometry" is intended to be understood as the locus of a generating line parallel to a predetermined direction and passing through a single point of a predetermined directrix curve, and consisting of substantially parallel The two opposing bases of the directrix are defined. A directrix that is always a closed line can be, for example, a square ( Figure 12 ),rectangle( Figure 13 ), round ( Figure 14 and 15 ), or can be ge...

Abstract

There is described a heat exchanger comprising a plurality of tubes arranged parallel with each other in order to form one or more tube bundles axially inserted into a shell. A first fluid, fed through one or more first inlet nozzles flows inside the tubes and a second fluid, fed through at least one second inlet nozzle, flows inside the shell in order to perform the heat exchange with the first fluid through the walls of the tubes. Inside the shell two or more baffles are formed and arranged perpendicularly with respect to the centre axis of the shell. Between each baffle and the inner wallsof the shell there is defined a corresponding window constituted by the cross-section for the passage of the second fluid, with a crossing direction parallel with the centre axis of the shell and thetubes, delimited by the free edge of the respective baffle on the one side and by the inner profile of the shell, at the intersection of the shell with the plane of the baffle, on the other side. Thecross-section for the passage of the second fluid placed between two adjacent baffles is constant and has a rectangular shape, that is to say, with all the inner angles congruent with each other. Eachbaffle has a rectangular shape. Each window has a rectangular shape and has no tubes therein.

Description

technical field [0001] The present invention relates generally to a heat exchanger with a tube bundle and a shell, and more particularly to the geometry of the three characteristic elements of a heat exchanger with a tube bundle and a shell, that is to say the one in which the fluid passages are created on the shell side The geometry of the inner part of the housing, the geometry of the transversal plate baffles, and the so-called "window" in the absence of a specific configuration of the tube extending in the window itself (so-called "tubeless window" configuration) geometric shapes. Background technique [0002] A heat exchanger with a tube bundle and a shell is a device that has the primary function of transferring heat between two fluids at different temperatures. The heat exchanger consists of a bundle of tubes, usually made of a material with high thermal conductivity, and is positioned inside a generally cylindrical receiver called the shell. The tube bundle can hav...
