Abstract
The invention discloses a low-resistance fin comprising a fin body. The fin body is formed by connecting multiple fin plates. Each fin plate consists of flat plates at two ends and a zigzag plate in the middle. The distance of every two adjacent fin plate is 2.2-2.7mm. Projections and recesses are arranged on the two end faces of each zigzag plate, and are distributed in a staggered manner. The depth of each recess is 1.2mm, and the opening distance thereof is 13.5-14.5 mm. As the distance of the adjacent fin plates is expanded, the fin plates are not easy to be jammed but easy to clean. As the depth of each recess of each fin plate is 1.2mm, and the opening distance of the recess of the fin plate is controlled within the range of 13.5-14.5mm, resistance of the fin is reduced on the premise of not influencing heat exchange efficiency, and the fin is less prone to jamming and is convenient to clean.
Description
Technical field
The present invention relates to a kind of fin, relate in particular to a kind of lower resistance fin.
Background technology
Fin, is arranged on the surface that need to carry out the hot heat-exchanger rig transmitting conventionally, plays the heat transfer sheet area that increases heat-exchanger rig, improves the effect of heat exchange efficiency.At present, fin on market is formed by connecting by polylith wing plate, yet the distance between its adjacent wing plate is generally 2mm, distance is less, when heat-exchanger rig is worked in the situation that environment is severe, the passage between wing plate is easily dirty, after the time grown, easily stop up, greatly reduce the heat exchange efficiency of heat-exchanger rig, and because the distance between adjacent wing plate is less, clean comparatively difficulty.
Summary of the invention
The object of the invention is to for the problems referred to above, a kind of lower resistance fin is provided, to solve existing fin, easily stop up, affect the problem of heat exchange efficiency, and the existing fin problem of easy cleaning not.
The object of the invention is to be achieved through the following technical solutions:
A kind of lower resistance fin, comprise fin body, described fin body is formed by connecting by polylith wing plate, every block of wing plate consists of the flat board at two ends and the winding sheet of middle, and the distance between adjacent wing plate is 2.2～2.7mm, is provided with protrusion, notch portion in the both ends of the surface of described winding sheet, and described protrusion and notch portion are interspersed, the degree of depth of described notch portion is 1.2mm, and its extended distance is 13.5～14.5mm.
As a preferred embodiment of the present invention, described winding sheet is wavy shaped configuration.
As another kind of preferred version of the present invention, described winding sheet is zigzag structure.
Preferably, the distance between described adjacent wing plate is 2.5mm.
Preferably, the extended distance of described notch portion is 14mm.
Preferably, described wing plate is 5.
Beneficial effect of the present invention is, described fin is by increasing the distance between adjacent wing plate, make fin be not easy to stop up, easily cleaning, and the wing plate notch portion degree of depth is 1.2mm, and the extended distance of wing plate notch portion is controlled within the scope of 13.5～14.5mm, fin is not being affected under the prerequisite of heat exchange efficiency, reduced resistance, thereby made fin be not easy to stop up, be convenient to clean.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of lower resistance fin of the present invention.
In figure:
1, wing plate; 11, flat board; 12, winding sheet; 121, notch portion; 122, protrusion.
The specific embodiment
Below in conjunction with accompanying drawing and by the specific embodiment, further illustrate technical scheme of the present invention.
Please refer to shown in Fig. 1, Fig. 1 is the structural representation of a kind of lower resistance fin of the present invention.
In the present embodiment, a kind of lower resistance fin, comprise fin body, described fin body is formed by connecting by 5 blocks of wing plates 1, and every block of wing plate 1 consists of the flat board 11 at two ends and the winding sheet 12 of middle, and the distance between adjacent wing plate 1 is 2.5mm, described winding sheet 12 is zigzag structure, in its both ends of the surface, be provided with the protrusion 122, the notch portion 121 that are interspersed, the degree of depth of described notch portion 121 is 1.2mm, and its extended distance is 14mm.
Although in above-described embodiment, winding sheet 12 is zigzag structure, the invention is not restricted to this, winding sheet 12 also can adopt wavy shaped configuration, as long as can reach, increase fin heat exchange area, increase the air agitation of flowing through fin surface, improve heat exchange efficiency effect.
The present invention has strengthened the distance between wing plate 1, and the degree of depth of wing plate 1 notch portion 121 is arranged on to 1.2mm, the extended distance of wing plate 1 notch portion 121 is controlled in 13.5～14.5mm, fin is not being affected under the prerequisite of heat exchange efficiency, reduced resistance, thereby make fin be not easy to stop up, be convenient to clean.
Above embodiment has just set forth basic principle of the present invention and characteristic; the present invention is not limited by above-described embodiment; without departing from the spirit and scope of the present invention, the present invention also has various variations and change, and these variations and change all fall in the claimed scope of the invention.The claimed scope of the present invention is defined by appending claims and equivalent thereof.
