Abstract
The utility model discloses a low resistance fin which comprises a fin body, wherein the fin body is formed by connecting a plurality of fin plates; each fin plate consists of flat plates at two ends and a middle winding plate; the distance between adjacent fin plates is 2.2-2.7 mm; upheaval parts and notch parts are formed in two end faces of the winding plates and are distributed in a staggered way; the depths of the notch parts are 1.2 mm; the opening distances of the notch parts are 13.5-14.5 mm. According to the low resistance fin, the distance between adjacent fin plates is increased, the fin is not easy to block and is easily cleaned, the depths of the notch parts of the fin plates are 1.2 mm, the opening distances of the notch parts of the fin plates are controlled in a range of 13.5-14.5 mm, under the premise of not influencing the heat exchange efficiency of the fin, the resistance is reduced, the fin is not easy to block, and the cleaning is facilitated.
Description
Technical field
The utility model relates to a kind of fin, relates 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.
Utility model content
The purpose of this utility model is for the problems referred to above, and a kind of lower resistance fin is provided, and to solve existing fin, easily stops up, and affects the problem of heat exchange efficiency, and the existing fin problem of easy cleaning not.
The purpose of this utility model 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 kind of preferred version of the present utility model, described winding sheet is wavy shaped configuration.
As another kind of preferred version of the present utility model, 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.
The beneficial effects of the utility model are, 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 utility model.
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 the technical solution of the utility model.
Please refer to shown in Fig. 1, Fig. 1 is the structural representation of a kind of lower resistance fin of the utility model.
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 utility model is not limited 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 utility model 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 utility model and characteristic; the utility model is not limited by above-described embodiment; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various variations and change, and these variations and change all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
