Reached that structural design is reasonable, heat transfer area is big, mechanical strength is high and non -deformable's mesh.

Description

A kind of ripple copper pipe
Technical field
This utility model discloses a kind of ripple copper pipe, belongs to heat exchanger tube technical field.
Background technology
Heat exchanger tube is the strength member of existing heat-exchange device, the common copper pipe on existing market, is being exchanged heat for producing There is heat transfer effect during device poor, volume is big, easy incrusted problem.The heat exchanger tube that most of heat transmission equipments are used both at home and abroad is equal For pipe or elliptical tube.The inner and outer wall of existing heat exchanger tube is usually the coaxial and parallel face of cylinder or elliptic cylinder, due to The internal face of this heat exchanger tube axis all the time parallel to heat exchanger tube so that by the fluid of heat exchanger tube, be difficult to form turbulent flow, from And affect the heat exchange of fluid and heat exchanger tube internal face.
Chinese patent application publication No. is CN203454886U, and Shen Qing Publication day is the utility model of on 2 26th, 2014 Patent helical bellows, including the helical groove that body and its outer wall are arranged, are formed with the inboard wall of tube body and helical groove Corresponding spiral fin, the outer surface of tube body product of the helical bellows are little, and when exchanging with ambient atmos, heat exchange efficiency is low, as During heat exchanger tube, under identical heat transfer effect, the set of heat exchange tubes into heat exchange box volume it is bigger than normal, it is impossible to meet heat exchanging under specific environment The requirement of casing product.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of reasonable in design, heat exchange area Greatly, high mechanical strength and on-deformable ripple copper pipe.
For achieving the above object, this utility model provides following technical scheme to realize:
A kind of ripple copper pipe, including the spiral fin of the helical groove on body, tube wall and correspondence helical corrugation, its It is characterised by:Close-packed arrays before and after the helical groove, the depth of the helical groove are 0.6~1.2 times of body wall thickness, institute The top for stating spiral fin is plane, and the height of the spiral fin is 0.5~1 times of helical groove depth.
As preferred:It is in the same size before and after the helical groove, it is in the same size before and after corresponding spiral fin.
As preferred:The ripple copper pipe is formed in one.
As preferred:The material of the ripple copper pipe can be copper tube, brass pipe.
As preferred:0.8~1 times for body wall thickness of the depth of the helical groove, the height of spiral fin is spiral 0.7~0.85 times of depth of groove.
As preferred:0.9 times for body wall thickness of the depth of the helical groove, the height of spiral fin is helical groove 0.8 times of depth.
In sum, this utility model has advantages below:
1st, overlapped by helical groove is arranged to front and rear edges, increased the external surface area of ripple copper pipe, improved The heat exchange efficiency of ripple copper pipe, can realize manufacturing the purpose of small size heat exchange box;2nd, arranged by the top by spiral fin For plane, as spiral fin is too high caused by helical groove depth is too deep, liquid in pipe constricted flow is set to plane Afterwards, reduce the height of spiral fin so that linear loss of the liquid in pipeline is little, while forming stronger turbulent flow, reduce The thickness of border trapped fluids layer, another part fluid then flow along the axial direction of body, while being subject to spiral fin to which The periodic disturbance of generation, so as to the heat transfer of monophasic fluid in enhanced tube, reaches the effect for improving heat exchanger effectiveness.
Description of the drawings
Fig. 1 is a kind of sectional view of ripple copper pipe of this utility model;
Fig. 2 is a kind of front view of ripple copper pipe of this utility model.
Specific embodiment
A kind of ripple copper pipe of this utility model is further described with reference to shown in Fig. 1 and Fig. 2.
A kind of ripple copper pipe, including the spiral fin of the helical groove 2 on body 1, tube wall and correspondence helical corrugation 3, it is characterised in that:Close-packed arrays before and after the helical groove 2, the depth of the helical groove 2 for 1 wall thickness of body 0.6~ 1.2 times, the top of the spiral fin 3 is plane, and the height of the spiral fin 3 is the 0.5~1 of 2 depth of helical groove Times.
It is in the same size before and after the helical groove 2, in the same size, the ripple copper pipe before and after corresponding spiral fin 3 It is formed in one, the material of the ripple copper pipe can be copper tube, brass pipe, preferably, the depth of the helical groove 2 is 0.8~1 times of 1 wall thickness of body, the height of spiral fin 3 are 0.7~0.85 times of 2 depth of helical groove.
Overlapped by helical groove 2 is arranged to front and rear edges, relatively with corrugated tube now on the market, increased The external surface area of ripple copper pipe is added, has improve the heat exchange efficiency of ripple copper pipe, when heat exchange box is manufactured, using this utility model Heat exchanger tube can be designed that compact, the high heat exchange box of heat exchange efficiency reaches the demand under specific occasion.
It is plane by the top of spiral fin 3 is set to, due to the too deep caused spiral fin of 2 depth of helical groove 3 is too high, liquid in pipe constricted flow, be set to it is plane after, reduce the height of spiral fin 3 so that liquid is in pipeline Linear loss it is little, while forming stronger turbulent flow, reduce the thickness of border trapped fluids layer;Another part fluid then along The axial direction flowing of body, while the periodic disturbance which produced by spiral fin 3, so as to the biography of monophasic fluid in enhanced tube Heat, reaches the effect for improving heat exchanger effectiveness.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to Above-described embodiment, all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.Should refer to Go out, for those skilled in the art, some improvement under the premise of without departing from this utility model principle and Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
