Description
Technical field
The utility model relates to air cooling, oil cooling field of heat exchangers, is specifically related to a kind of spiral fin coil.
Background technology
Tube bank in air-Cooled Chiller is made up of multiple finned tube, finned tube realizes medium and extraneous heat exchange, and the medium in finned tube has higher pressure, in order to improve the intensity of finned tube, improve its heat exchange property simultaneously, the thickness of usual aluminum pipe finned tube is all larger, makes finned tube aluminum amount large, and it uses heat resistance poor, for in adverse circumstances operating mode, need the finned tube seeking a kind of high temperature resisting corrosion resisting, the technological requirement of heat radiation can be reached, its life-span can be ensured again.
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, provides one can be adapted to adverse circumstances operating mode, can reach the technological requirement of heat radiation, can ensure again the new spiral finned tube of the high temperature resisting corrosion resisting in its life-span.
The technical solution of the utility model is achieved in that
New spiral finned tube, comprising: base tube and helical fin, and base tube evenly offers multiple mounting groove vertically, and helical fin is embedded in mounting groove, and helical fin comprises base portion and fin part, is provided with bend between base portion and fin part.
Preferably, base tube is T2 copper tube, White Copper Tubes or stainless steel tube.
Preferably, the outer surface of base tube and helical fin is provided with zinc coat.
Preferably, fin part comprises conical finned and square fin, and square fin is fixedly connected with mounting groove.
Preferably, the thickness of the cross section of fin part reduces towards periphery along its length.
The utility model evenly offers multiple mounting groove vertically due to base tube, is equipped with fin in mounting groove, has corrosion resistant performance.Therefore have and can be adapted to adverse circumstances operating mode, the technological requirement of heat radiation can be reached, the advantage in its life-span can be ensured again.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As depicted in figs. 1 and 2, new spiral finned tube comprises base tube 2 and helical fin 1, and cold-producing medium can flow in base tube 2, and base tube 2 can be formed by metal material.Helical fin 1 can be formed by the outer surface being wound on base tube 2, the shape of cross section is along its length made to be roughly " L " type, preferably, base tube 2 evenly offers multiple mounting groove 5 vertically, be equipped with helical fin 1 in mounting groove 5, the outer surface of base tube 2 and helical fin 1 is provided with zinc coat.
Helical fin 1 can be formed by the metal material of such as steel or aluminium.Preferably, helical fin 1 also comprises base portion 4 and fin part, and base portion 4 can be attached to base tube 2 outer surface, and fin part can extend along the diametric(al) of base tube 2.Further, base portion 4 and fin part can be formed in the both sides of bend 3.
Bend 3 is a fluted body structure, and the thickness D1 of groove is less than the thickness D2 of base portion 4, and correspondingly, the bend 3 of helical fin 1 can have minimum thickness in the element of helical fin 1, and bend 3 can more easily bend like this.
In addition, fin part can be formed as almost vertical with base portion 4, and the cross section of the length direction of such helical fin 1 can have better L shape.Bend 3 due to helical fin 1 is bending easier, therefore can reduce helical fin 1 and be wound on the internal diameter after on base tube 2.Correspondingly, because the diameter of base tube 2 can be reduced, so helical fin 1 firmly can closely depend on the pipe with the small diameter being equal to or less than 8mm.
Fin part comprises conical finned 6 and square fin 7, can be formed as making the thickness of its cross section to reduce towards periphery along its length, therefore the peripheral part of helical fin 1 can widely launch, equally, because the peripheral part of helical fin 1 can widely launch, fin part can not play fold.
According to the utility model, because the bend 3 of helical fin 1 is formed in the groove portion that the length direction along helical fin 1 caves in, have on the pipe of small diameter so the base portion 4 of helical fin 1 can easily be tightly wound in.Further, because helical fin 1 is designed such that the thickness of its cross section along its length reduces towards periphery, so the outer peripheral portion of fin part can widely launch.Further, because bend 3 can increase heat exchange area further, so can heat exchanger effectiveness be improved.
The utility model, due to base tube evenly offering multiple annular embedding groove vertically, is equipped with fin in annular embedding groove, and make radiating effect better, the outer surface of base tube and fin is provided with zinc coat, makes finned tube have corrosion resistant performance.Therefore the mosaic finned tube of this high temperature resisting corrosion resisting has and can be adapted to adverse circumstances operating mode, can reach the technological requirement of heat radiation, can ensure again the advantage in its life-span.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
