Abstract

The invention relates to a sheet structure used for a plate heat exchanger, which belongs to the technical field of heat exchanger manufacturing. The sheet mainly comprises a plate body which is provided with rippled zones, and is characterized in that the plate body is provided with a long slot, the rippled zones are distributed on both sides of the long slot, the ripples at both sides are in an asymmetric structure, i.e. one side is provided with the wave crest, the other corresponding side is provided with the trough, the wave crest of the rippled zone at one side is provided with a groove, and the trough corresponding to the wave crest side is provided with a similar groove. The invention has the advantages of simple structure, good heat transfer performance, low manufacturing cost, easy processing, wide applicable scope and the like.

Description

A kind of plate type heat exchanger sheet structure

Technical field

The invention belongs to heat exchanger manufacturing technology field, particularly relate to a kind of plate type heat exchanger sheet structure.

Background technology

At present, traditional plate type heat exchanger plate has two kinds, and is a kind of for waiting runner form, another kind of for not waiting runner form.The corrugated regions shape of plate is seen Fig. 3 a and Fig. 3 b, and the plate of this kind structure only can be assembled into a kind of product of form.Plate assembling form is seen Fig. 3 c and 3d, the transversal Fig. 3 e that meets personally after the plate assembling; This plate advantage is that corrugated form is simple, handling ease.But because ripple is netted after the plate assembled upside down, this causes and form several " walls " in plate, and " wall " hindered passing through of medium, and be more obvious for containing particle media especially.If the increasing ripple degree of depth simply can cause the increase of difficult forming and material consumption and the reduction of heat transfer property, effect is also not obvious simultaneously.

Summary of the invention

The present invention is for solving the plate type heat exchanger sheet structure that the technical problem that exists in the known technology provides a kind of simple in structure, good heat-transfer, low cost of manufacture, is easy to process.

The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is: a kind of plate type heat exchanger sheet structure, this plate mainly comprises plate body, the corrugated regions that plate body is provided with is characterized in that, described plate body is provided with elongated slot, described corrugated regions is distributed in the both sides of elongated slot, the ripple of both sides adopts unsymmetric structure, and promptly a side is a crest, and corresponding opposite side is a trough, the crest of a described side corrugated regions is provided with groove, and the trough of corresponding crest side is provided with same groove.

The present invention can also adopt following technical measures: the degree of depth of described groove is 1/3～2/3 of a crest.Advantage and good effect that the present invention has are: because the present invention adopts said structure, this plate can be by common rotation mode assembling, described adjacent plate groove direction unanimity, and this mounting means, circulation does not all exert an influence to media of both sides.The present invention also can assemble by the upset mode, and assembling back forms and do not wait runner plate type heat exchanger product, and the inside passage of adjacent plate groove direction forms narrow runner, the medium that promptly negotiablely clean as clean water, viscosity is low.Groove can increase the liquid disturbance, improves heat transfer property; The outside passage of adjacent plate groove direction forms wide runner, negotiable particle, the fiber liquid of containing; Outside and the staggered groove of direction is equivalent to a small tubes, helps particle, fibre stream mistake, so the present invention has simple in structure, good heat-transfer, low cost of manufacture, is easy to advantages such as processing.

Among the figure: 1, plate body; 2, corrugated regions; 3, elongated slot; 4, groove.

The specific embodiment

For further understanding summary of the invention of the present invention, characteristics and effect, now exemplify following examples, and conjunction with figs. is described in detail as follows: see also Fig. 1 and Fig. 2, a kind of plate type heat exchanger sheet structure, this plate mainly comprises plate body 1, the corrugated regions 2 that plate body 1 is provided with, on plate body 1, be provided with elongated slot 3, corrugated regions 2 is distributed in the both sides of elongated slot 3, and the ripple of both sides adopts unsymmetric structure, and promptly a side is a crest, corresponding opposite side is a trough, the crest of a described side corrugated regions is provided with groove, and the trough of corresponding crest side is provided with same groove 4, and the degree of depth of groove is 1/3～2/3 of the ripple degree of depth.

This plate can be assembled by common rotation mode: the plate bellows-shaped is seen Fig. 1 a behind the Rotate 180 °, Rotate 180 ° latter two plate groups assembling structure schematic diagram is seen Fig. 1 b, the cross section structure schematic diagram of Rotate 180 ° latter two plate assembling is seen Fig. 1 c, realize in the accompanying drawing that part is a crest, dotted line is a trough, and M and U are used for expression rotation front and back corresponding relation in the accompanying drawing; Described adjacent plate groove direction unanimity, this mounting means, circulation does not all exert an influence to media of both sides.

Advantage of the present invention is mainly reflected in and can assembles by the upset mode: upset back plate bellows-shaped figure sees Fig. 2 a, latter two plate groups assembling structure schematic diagram that overturns is seen Fig. 2 b, the cross section structure schematic diagram of latter two plate assembling of overturning is seen Fig. 2 c, realize in the accompanying drawing that part is a crest, dotted line is a trough, and M and U are used for expression upset front and back corresponding relation in the accompanying drawing; This kind mounting means, assembling back forms products such as not waiting the runner plate type heat exchanger, and promptly the inside passage of adjacent plate groove direction forms narrow runner E, the medium that promptly negotiablely clean as clean water, viscosity is low, groove can increase the liquid disturbance, improves heat transfer property; The outside passage of adjacent plate groove direction forms wide runner F, negotiable particle, the fiber liquid of containing; Outside and the staggered groove of direction is equivalent to a small tubes, helps particle, fibre stream mistake.

In sum the present invention have simple in structure, good heat-transfer, low cost of manufacture, be easy to processing, advantage such as applied widely.

The above only is the preferable example of executing of the present invention, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of the present patent application claim change and modification, all fall into technical scope of the present invention.
