PACKAGE OF PLATES FOR HEAT EXCHANGER

(OPTIONS)

The utility model relates to sets of plate elements with means for increasing the heat transfer area, in particular, fins, depressions designed for assembly in the form of stacked sets and can be widely used for air recirculation, in heat exchangers in public utilities, chemical, oil and refrigeration industry.

A known package of plates for a heat exchanger described in. PCT No. 91-16589 Plate evaporator according to class F28F 3/06, 3/02, s. 04/15/91, op.31.10.91.

The known package consists of several adjacent heat exchange plates equipped with corrugations in the form of protrusions and depressions, the corrugations on each plate forming several zones with different directions of the corrugations and on adjacent plates some of the zones have the opposite direction of the corrugations, and some of the zones have the same direction of the corrugations .

A disadvantage of the known package is the need to use elements during assembly that ensure the plates are placed at a certain distance from each other to create channels for the flow of heat transfer fluid, and the selection of plates with alternating zones with different corrugations during assembly.

A known package of plates for a heat exchanger, described in s. UK No. 2236841 Heat exchanger, according to CL F28F 13/00, z. 08/09/89, op. 04/17/91. The steps for turbulizing the flows of heat-exchange fluids are channels for supplying these media, and the semicylindrical protrusions extending over the entire width of the plate serve to create the necessary gap between the plates, while on the adjacent plates the channels for supplying heat-exchange media are arranged mutually perpendicularly. A disadvantage of the known package is the need to perform special elements to obtain the necessary gap between the plates and to ensure a certain mutual orientation of the plates when assembling them into a package. Closest to the technical nature of the claimed is a package of plates for a heat exchanger described in the same certificate of the Russian Federation No. 10861 for a utility model according to class. F28D 1/02, F28F 3/00, 3 / 02.3 / 08, 03/03/03, Opt. 08/16/99, and selected as a prototype. The known package of plates consists of alternating, adjacent to each other, smooth plates and corrugated insert plates having corrugations on the surface of the corrugation in the form of protrusions and depressions alternating on both axes of the plane of the insert plate. A disadvantage of the known package of plates is that in it for the manufacture of plate-inserts should be used only such a material that can long and hard to store the shape of the protrusions and depressions, which limits the possibility of using materials and increases the cost of the heat exchanger. The manufacture of such a heat exchanger is not very technologically advanced due to the complexity of the implementation of shshstin-inserts. The purpose of the claimed utility model is to expand the possibilities of using materials for the manufacture of plates and reduce the cost of the heat exchanger while increasing the manufacturability of its manufacture. , V - in the first embodiment, in a plate package for a heat exchanger, consisting of alternating smooth plates adjacent to each other and corrugated insert plates having corrugations on the surface in the form of protrusions and depressions alternating along both axes of the insert plate plane, ACCORDING TO THE USEFUL MODEL , the corrugations on the insert plates are formed by volumetric geometric elements mechanically attached to the plane of the insert plate on both sides thereof; - in the second embodiment, in a plate package for a heat exchanger containing adjacent plates, having corrugations on the surface of the corrugations in the form of protrusions alternating along both axes of the plane, ACCORDING TO THE USEFUL MODEL, corrugations are formed by volumetric geometric elements mechanically attached to the same sides of the plates; - in the third embodiment, in a plate package for a heat exchanger, including smooth plates, ACCORDING TO THE USEFUL MODEL, smooth plates are separated by lattice inserts formed from interconnected volumetric geometric elements. In the first embodiment, the package consists of shshstin inserts with corrugations adjacent to smooth plates in the form of volumetric geometric elements that are mechanically attached to both sides of their surface; in the second version, a package of only plates with corrugations in the form of volumetric geometric elements attached to the same sides of plates , and in the third version - a package of lattice inserts adjacent to smooth plates of interconnected volumetric geometric elements provides good heat transfer performance ka, excluding the adhesion of the plates during the passage of the liquid, and the possibility of making its plates from any materials, up to plastics, since the use of corrugations in the form of volumetric geometric elements mechanically attached to the surface of the plates does not require the ability of the material to retain shape for a long and rigid corrugation, which reduces the cost of manufacturing a heat exchanger. The implementation of the corrugations in the form of volumetric geometric elements, mechanically attached to the surface of the plates, makes the heat exchanger more technological in manufacturing. The inventive package of plates for the heat exchanger in all its variants is new in comparison with the prototype, differing from it in achieving the specified result: in the first embodiment, the corrugation on the insert plates in the form of volumetric geometric elements mechanically attached on both sides to the surface of the insert plate; -in the second embodiment, the implementation of the package only of plates with corrugations made in the form of mechanically attached to the same sides of the surfaces of the plates of volumetric geometric elements; - in the third embodiment, instead of corrugated plates, inserts of gratings from interconnected volumetric geometric elements. The claimed technical solution in all its variants can be widely used for air recovery, in heat exchangers in utilities, chemical, oil and refrigeration industries and therefore meets the criterion of industrial applicability. The utility model is illustrated by drawings, which are presented on:

-Fig. 4 is a sectional view of the packet according to the second embodiment;

-fig. 5 - performing inserts according to the third embodiment; -Fig. 6 is a sectional view of the package according to the third embodiment.

The package of plates for the heat exchanger according to the first embodiment (see, Fig. 1, 2) contains alternating, adjacent to each other ironing plates 1 and corrugated plates - inserts 2, the corrugations of which are formed by volumetric geometric elements 3, mechanically attached to both sides of the plate-inserts 2 , and alternating on both axes of the plane of the insert plate 2.

The package of plates of the heat exchanger in the second embodiment (see Fig. 3, 4) contains adjacent plates 4, to the same sides of which the volumetric geometric elements 5, acting as corrugations, are mechanically attached.

The package of plates in the third embodiment (see Fig. 5, 6) contains alternating, adjacent to each other, smooth plates 6 and lattices 7 of interconnected volumetric geometric elements 8.

In all variants, the plates are stacked, their edges are smooth, which makes it easy to seal the channels for the passage of heat-transfer media during assembly, for example, using rubber absorbing gaskets (not shown in the drawings). Volumetric geometric elements can have any shape - balls, cones, pyramids, cubes, etc. They can be attached to the surfaces of the plates, for example, with glue or made simultaneously with the plate, or welded or screwed to it. The plates can be made depending on the expected operating conditions from thin metal sheets or from plastic (even, for example, from a plastic film); volumetric geometric elements - from plastic, metal, etc. A lattice of volumetric geometric interconnected elements (third option) can be made of plastic by stamping or molding. The assembly of the plates in the package can be performed in any known manner, for example, using fasteners (not shown in the drawings). When supplying heat-exchanging or air media to the heat exchanger, corrugations in the form of volumetric geometric elements play the role of turbulators and at the same time play the role of elements that specify the distance between the plates. Due to the alternation of volumetric geometric elements-corrugations along both axes of the plate, channels are formed for passing heat-exchanging air or fluids. These media can be fed through the heat exchanger plates in any direction. Compared with the prototype, the claimed package of plates for the heat exchanger in all its variants allows the use of a wider range of materials, is cheaper and more affordable, and more technologically advanced to manufacture.
