Abstract
The utility model relates to a fin type condensing tube, which belongs to the technical field of refrigeration. The condensing tube consists of a tube body and fins positioned on the outside of the tube body. The condensing tube has the following characteristics that: the fins are spirally extended along the axial direction of the tube body on the outer wall of the tube body, and are tightly combined with the outer wall of the tube body, wherein fin folds of the fins are alternately deflected toward both sides to form waves. Compared with the prior art, the technical scheme has the following advantages that: the roots of the fins are tightly combined with the outer wall of the tube body, so that air gaps do not exist in between, and the self structures of the fins are formed into waves.
Description
Technical field
The utility model belongs to refrigeration technology field, is specifically related to a kind of finned condenser pipe, is used to make the condenser of refrigerator or showcase.
Background technology
China utility model patent Granted publication CN201206922Y has recommended a kind of spiral condenser, has specifically provided fin with an integral body and with the spiral technology enlightenment that is wrapped in (body) on the evaporimeter.This scheme has advantages such as long-pending little, low cost of manufacture of collective and perfect heat-dissipating in one for prior art.But there is following shortcoming: the one, stop with clamp owing to only fin is wound on the body and at two ends, thereby have air gap inevitably between the outer wall of fin and body, influence radiating effect, because air is the non-conductor of heat; The 2nd, the structure of the fish gill shape fin on the surface of fin is lost rationally, can not give play to the ultimate attainment effect that increases radiating surface and improve radiating effect.In view of this, be necessary to improve.
Summary of the invention
Task of the present utility model is to provide a kind of fin to combine with body reliably and the self structure of fin is rationally used the finned condenser pipe that enlarges area of dissipation and promote radiating effect.
Task of the present utility model is finished like this, a kind of finned condenser pipe, comprise body and be positioned at the outer fin of body, be characterised in that: described fin extends and closely is incorporated on the outer wall of body towards the body axis direction with helical form at the outer wall of described body, wherein, the wing of fin is folded to alternately skew and constitute waveform of both sides.
Body described in the utility model is a galvanized pipe, and described fin is a steel band, and the steel band solder bond is on the outer wall of body.
The height of fin described in the utility model is 1.5-4mm, and the number of described corrugated wave number on circumference is 10-20.
The technical scheme that the utility model provides advantage compared with the prior art: the base portion of fin and the outer wall of body are combined closely, and do not have air gap between the two, and self structure of fin is constituted waveform.
Description of drawings
Accompanying drawing is a preferred embodiment structure chart of the present utility model.
The specific embodiment
Ask for an interview accompanying drawing, fill the post of body 1 by accurate galvanized pipe, fill the post of fin 2 by steel band, fin 2 extends and does not have the unoccupied place by the mode of welding and combine closely on the outer wall of body 1 towards the axis direction of body 1 with spiral status ground at the outer wall of body 1, the height of fin 2 is 1.5-4mm, being 2-3.5mm preferably, is 3mm better, and present embodiment is selected 3mm.The wing folding 21 of fin 2 replaces the corrugated wave number that is offset and forms to both sides and is: the number on the circumference of fin 2 is preferably 10-20, be 12-18 preferably, be 16 better, present embodiment is selected 16, promptly with one every one mode, 8 offset to one side, and other 8 are offset to opposite side.Can be processed into the condenser of different shape by the resulting finned condenser pipe of present embodiment, the notion of the condenser of alleged here different shape is meant carries out the crooked shape that is constituted to body 1.For example it can be bent to various condenser by the schematic structure of Chinese invention patent Granted publication CN131401C.
