Abstract
The utility model relates to a heat exchanger plate sheet provided with concave-convex pressed patterns on the edges. The heat exchanger plate sheet comprises medium inlets, medium outlets, guide regions, a sealing groove, heat exchange regions and the heat exchanger plate sheet edges, wherein upwardly projected table surfaces and downwardly recessed groove surfaces are distributed on the heat exchanger plate sheet edges and are alternately arranged along the heat exchanger plate sheet edges; and the cross sections of the upwardly projected table surfaces or the downwardly recessed groove surfaces are in the shape of a rectangle or an isosceles trapezoid. By setting the upwardly projected table surfaces or the downwardly recessed groove surfaces on the edges of the heat exchanger plate sheet and bonding the upwardly projected table surfaces of the heat exchanger plate sheet with the downwardly recessed groove surfaces of the adjacent plate sheet, a honeycomb structure is formed on the overall side surface of the heat exchanger plate sheet, so that the strength of a heat exchanger plate sheet set is enhanced and the bearing capacity of a sealing gasket is increased.
Description
Technical field
The utility model relates to a kind of heat exchanger plate, relates in particular to a kind of edge of heat exchanger plate sheet with the plate-type heat exchanger slab of die mould.
Background technology
Plate type heat exchanger is by many corrugated heat transferring plates, by certain interval, compresses the dismountable heat transmission equipment that forms by rubber sheet gasket.During the plate assembling, two groups of alternative arrangements, with binding agent the rubber seal lath is fixed between plate and the plate, its effect is to prevent fluid leakage and make the narrow net form runner of formation between two plates, the heat exchanger plate sheet that for this reason needs arrangement is fitted together applies a permanent thrust, with the sealing of the rubber seal lath between assurance plate and the plate, if but permanent thrust is balanced not, make possibly rubber seal lath generation deformation displacement, cause the leakage of heat exchanger plate; If permanent thrust is excessive in addition, this also can produce certain micro-deformation the heat exchanger plate sheet under the effect of permanent thrust, affect the sealing of whole heat-exchange system and the service life of heat exchanger.
The utility model content
The purpose of this utility model provides a kind of heat exchanger plate sheet edge with the heat exchanger plate of concavo-convex die mould, can strengthen the intensity of heat exchanger plate sheet group, improves the bearing capacity of heat exchanger gasket seal.
The technical scheme that realizes the utility model purpose is: a kind of plate edge is with the heat exchanger plate of concavo-convex die mould, comprise the medium import and export, guiding region, seal groove, heat exchange zone and heat exchanger plate limit, wherein the heat exchanger plate limit is provided with epirelief table top and recessed groove face, and epirelief table top and recessed groove face are along each limit alternative arrangement on heat exchanger plate limit.
The longitudinal cross-section of described epirelief table top or recessed groove face is shaped as rectangle or isosceles trapezoid.
The utlity model has positive effect: by the edge at the heat exchanger plate sheet epirelief table top and recessed groove face are set, and with the epirelief table top of heat exchanger plate and the recessed groove face face face joint of its adjacent plate, so that the whole side of heat exchanger plate forms alveolate texture, strengthen the intensity of heat exchanger plate sheet group, improved the bearing capacity of gasket seal.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model according to specific embodiment also by reference to the accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the partial three dimensional perspective diagram on heat exchanger plate limit.
Fig. 3 is three heat exchanger plate limit alveolate texture schematic diagrames after the heat exchanger plate assembling.
Wherein, 1, medium imports and exports, 2, guiding region, 3, seal groove, 4, heat exchange zone, 5, the heat exchanger plate limit, 6, the epirelief table top, 7, recessed groove face, 8, upper heat exchanger plate, 9, middle heat exchanger plate, 10, lower heat exchanger plate.
The specific embodiment
As depicted in figs. 1 and 2, a kind of plate edge is with the heat exchanger plate of concavo-convex die mould, comprise medium import and export 1, guiding region 2, seal groove 3, heat exchange zone 4 and heat exchanger plate limit 5, wherein heat exchanger plate limit 5 is provided with epirelief table top 6 and recessed groove face 7 compositions, epirelief table top 6 and recessed groove face 7 are along each limit alternative arrangement on heat exchanger plate limit 5, and the longitudinal cross-section of epirelief table top 6 and recessed groove face 7 is shaped as rectangle or isosceles trapezoid.
In the assembling process, each heat exchanger plate limit is its contiguous heat exchanger plate limit Rotate 180 ° relatively, pressing gets final product fully, the heat exchanger plate limit 5 of each heat exchanger plate contacts with each other and combines at this moment, and the epirelief table top 6 on every heat exchanger plate limit is all faced with 7 of the recessed groove faces on the heat exchanger plate limit that is adjacent and is connected together.For example, as shown in Figure 3, three heat exchanger plates in total upper, middle and lower, the epirelief table top 6 of middle heat exchanger plate 9 are faced with 7 of the recessed groove faces of upper heat exchanger plate 8 and are connected together, the recessed groove face 7 on middle heat exchanger plate limit 9 and epirelief table top 6 plane-plane contacts of lower heat exchanger plate 10; So the heat exchanger plate limit between the whole heat exchanger plate presents a kind of cellular connected mode, this structure can effectively be strengthened the intensity of heat exchanger plate sheet group, improves the bearing capacity of sealing gasket seal.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
