Abstract
The utility model discloses an efficient spiral plate heat exchanger which comprises a double-spiral heat exchange plate in a shell, the double-spiral heat exchange plate is formed by coiling two long metal plates, a plurality of spherical bosses with equal altitude are pressed on each metal plate and are distributed on the metal plate in a rectangular array, and the spherical bosses on the two metal plates are arranged in a staggered manner. The efficient spiral plate heat exchanger has a simple structure, long service life, large effective heat exchange area and high heat exchange efficiency, and is easy to produce and process.
Description
Technical field
The utility model relates to a kind of heat-exchanger rig, especially a kind of spiral-plate heat exchanger.
Background technology
Spiral-plate heat exchanger has advantages such as the heat transfer runner is long, the runner spacing is big, compact conformation; The many employings of spiral-plate heat exchanger of the prior art are put together by two long sheet packs and are rolled into the double helix heat exchanger plates, on every steel plate, are welded with spacing column equably.This heat exchanger will need the manual work of labor to fix the welding spacing column in production process, and production efficiency is low, owing on steel plate, welded a large amount of spacing columns; Spacing column is prone to come off in the process of rolling; Cause the runner spacing uneven, intensity reduces, and in use is prone to take place stress corrosion phenomena at the pad place; Influence the service life of heat exchanger, and the welding of spacing column has also reduced the effective heat exchange area of spiral heat exchanger plates.
The utility model content
The technical problem that utility model will solve is: a kind of high-efficiency helical sheet heat exchanger is provided, and this heat exchanger structure is simple, long service life, effective heat exchange area is big, heat exchange efficiency is high, and is easy to production and processing.
The technical scheme that the technical solution problem is taked: a kind of high-efficiency helical sheet heat exchanger; Comprise the double helix heat exchanger plates in the housing; Said double helix heat exchanger plates is rolled by two long metal sheets and forms; On every metallic plate, be suppressed with high spherical surface hills such as a plurality of, spherical surface hill is rectangular arranged in arrays on metallic plate, and the spherical surface hill dislocation on two metallic plates is arranged.
Improvement as the utility model: after the double helix heat exchanger plates launched, the spherical surface hill projection in the plane on two metallic plates was equilateral triangle and distributes.
Beneficial effect: the high-efficiency helical sheet heat exchanger of the utility model forms, on every metallic plate, is suppressed with high spherical surface hills such as a plurality of owing to adopted said double helix heat exchanger plates to be rolled by two long metal sheets; Spherical surface hill is rectangular arranged in arrays on metallic plate, and the technical scheme that the spherical surface hill dislocation on two metallic plates is arranged is utilized spherical surface hill to replace and is welded on two spacing columns on the metallic plate in the common spiral-plate heat exchanger; Therefore, this spiral-plate heat exchanger has characteristics simple in structure, as to be easy to production and processing, only on metallic plate, suppresses spherical surface hill with machine in process of production and gets final product; Need not the traditional spacing column of human resources welding of labor, greatly improved the production efficiency of spiral-plate heat exchanger, shortened production man-hour; And can effectively prevent because the stress corrosion that the spacing column welding causes; Having prolonged the service life of spiral-plate heat exchanger, is the technical characterictic of spherical surface hill owing to adopted convex design, makes the spiral plate of this heat exchanger when compacting, be difficult for producing the stretching crackle; And the attenuate amount of high spot is little; Attenuate is even, and therefore, the high-efficiency helical sheet heat exchanger quality of the utility model is more reliable; Simultaneously, this spherical surface hill has increased the surface area of spiral plate on the one hand, and two spiral plates have realized that some contact is supported on the other hand, have reduced the contact area of two spiral plates, and effective heat exchange area is significantly improved, and heat exchange efficiency is also improved significantly; In addition, this heat exchanger when work, form turbulent flow more easily during pit after MEDIA FLOW is crossed sphere and sphere, so the heat exchange efficiency of the high-efficiency helical sheet heat exchanger of the utility model is higher; Because after having adopted the double helix heat exchanger plates to launch; Spherical surface hill projection in the plane on two metallic plates is the technical characterictic that equilateral triangle distributes; Make the pit after the medium that flows through from sphere is diverted to another cricket face rapidly, its turbulence effects is better, the heat exchange better effects if.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 rolls sketch map for the double helix heat exchanger plates of the high-efficiency helical sheet heat exchanger of the utility model;
Fig. 2 is that the A-A of double helix heat exchanger plates of Fig. 1 high-efficiency helical sheet heat exchanger is to cutaway view.
The specific embodiment
As shown in Figure 1; The high-efficiency helical sheet heat exchanger of the utility model; Comprise the double helix heat exchanger plates 1 in the housing; Said double helix heat exchanger plates is rolled by two long metal sheets (11,12) and forms, and on every metallic plate, is suppressed with high spherical surface hills 13 such as a plurality of, and spherical surface hill is rectangular arranged in arrays on metallic plate; As shown in Figure 2, the spherical surface hill dislocation on two metallic plates is arranged.In order to obtain better turbulence effects, after the double helix heat exchanger plates launched, the spherical surface hill projection in the plane on two metallic plates was equilateral triangle and distributes.
Claims (2)
1. high-efficiency helical sheet heat exchanger; Comprise the double helix heat exchanger plates in the housing; Said double helix heat exchanger plates is rolled by two long metal sheets and forms; It is characterized in that: on every metallic plate, be suppressed with high spherical surface hills such as a plurality of, spherical surface hill is rectangular arranged in arrays on metallic plate, and the spherical surface hill dislocation on two metallic plates is arranged.
2. high-efficiency helical sheet heat exchanger according to claim 1 is characterized in that: after the double helix heat exchanger plates launched, the spherical surface hill projection in the plane on two metallic plates was equilateral triangle and distributes.
