Abstract
The utility model discloses a spiral plate heat exchanger free of distance posts, which comprises two spiral heat exchange plates arranged in a casing. The two spiral heat exchange plates are formed by rolling two metal plates, one plate is a flat metal plate, and concave supporting points and convex supporting points are pressed evenly on the other metal plate in staggered mode. The height of the convex supporting points is the same. The concave depth of the concave supporting points is identical. The heat exchanger is simple in structure, long in service life, high in heat exchange efficiency and convenient 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 fixing welding of the manual work spacing column of labor in production process; Production efficiency is low, and, owing on steel plate, welded a large amount of spacing columns; Make this heat exchanger that stress corrosion phenomena in use take place at the pad place easily, influence the service life of heat exchanger.
The utility model content
The technical problem that utility model will solve is: a kind of no spacing column spiral-plate heat exchanger is provided, and this heat exchanger structure is simple, long service life, heat exchange efficiency are high, and production and processing is convenient.
The technical scheme that the technical solution problem is taked: a kind of no spacing column spiral-plate 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, a Zhang Weiping metallic plate wherein, and staggered equably punching press has the protruding strong point and the recessed strong point on another metallic plate; The height of all protruding strong points is identical, all recessed strong points recessed identical deeply.
Improvement as the utility model: the said protruding strong point and the recessed strong point are the protruding strong point and the recessed strong point of truncated cone-shaped.
Further improvement as the utility model: have the dual-side of the metallic plate of the protruding strong point and the recessed strong point to be provided with the band of the no protruding strong point and the recessed strong point in punching press.
Beneficial effect: the no spacing column spiral-plate heat exchanger of the utility model, owing to adopted the double helix heat exchanger plates that comprises in the housing, said double helix heat exchanger plates is rolled by two long metal sheets and forms; A Zhang Weiping metallic plate wherein, staggered equably punching press has the protruding strong point and the recessed strong point on another metallic plate, and the height of all protruding strong points is identical; The recessed dark identical technical scheme of all recessed strong points matches with flat metal plate with the protruding strong point and the recessed strong point, substitutes the mode of the weldering of cloth on two metallic plates spacing column in the conventional spiral-plate heat exchanger; Therefore, this no spacing column heat exchanger has characteristic of simple structure, only gets final product with the machine protruding strong point of punching press and recessed strong point on a metallic plate in process of production; 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; Prolonged the service life of spiral-plate heat exchanger; Since on flat metal plate punching press the protruding strong point and the recessed strong point, increased the heat transfer area of heat exchanger, and strengthened the flow-disturbing effect; Therefore, the no spacing column spiral-plate heat exchanger heat exchange efficiency of the utility model is higher; Owing to adopted the protruding strong point and the recessed strong point of truncated cone-shaped; Make the no spacing column spiral-plate heat exchanger of the utility model in the process that rolls; The strong point is less to the interference that rolls, and the deflection of the strong point is little, and the spiral-plate heat exchanger quality of producing is more stable; Because having adopted in punching press has the dual-side of the metallic plate of the protruding strong point and the recessed strong point to be provided with the technical characterictic of the band of the no protruding strong point and the recessed strong point; Make the no spacing column spiral-plate heat exchanger of the utility model manufacture in the process in production; Effectively avoid the influence of the protruding strong point and the recessed strong point to the sealing of spiral-plate heat exchanger end cap portions; Make its production and processing convenient, quality is more reliable.
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 no spacing column spiral-plate heat exchanger of the utility model;
Fig. 2 does not have the A-A of double helix heat exchanger plates of spacing column spiral-plate heat exchanger to cutaway view for Fig. 1.
The specific embodiment
A kind of no spacing column spiral-plate heat exchanger; Comprise the double helix heat exchanger plates in the housing; As shown in Figure 1, said double helix heat exchanger plates 1 is rolled by two long metal sheets and forms, wherein a Zhang Weiping metallic plate 3; Staggered equably punching press has the protruding strong point 21 and the recessed strong point 22 on another metallic plate 2, has the dual-side of the metallic plate of the protruding strong point and the recessed strong point to be provided with the band of the no protruding strong point and the recessed strong point in punching press.As shown in Figure 2, the height of all protruding strong points is identical, all recessed strong points recessed identical deeply, and the said protruding strong point and the recessed strong point are the protruding strong point and the recessed strong point of truncated cone-shaped.
Claims (3)
1. no spacing column spiral-plate heat exchanger; Comprise the double helix heat exchanger plates (1) in the housing; It is characterized in that: said double helix heat exchanger plates is rolled by two long metal sheets and forms, a Zhang Weiping metallic plate (3) wherein, and staggered equably punching press has the protruding strong point (21) and the recessed strong point (22) on another metallic plate (2); The height of all protruding strong points is identical, all recessed strong points recessed identical deeply.
2. no spacing column spiral-plate heat exchanger according to claim 1 is characterized in that: the said protruding strong point and the recessed strong point are the protruding strong point and the recessed strong point of truncated cone-shaped.
3. no spacing column spiral-plate heat exchanger according to claim 1 and 2 is characterized in that: have the dual-side of the metallic plate of the protruding strong point and the recessed strong point to be provided with the band of the no protruding strong point and the recessed strong point in punching press.
