Abstract
The utility model belongs to a stainless steel pipe fitting, in particular to a stainless steel external corrugated tube for a heat exchanger. The stainless steel external corrugated tube comprises a stainless steel pipe body, which is characterized in that the stainless steel pipe body is provided with a plurality of turbulent flow expansion joints, and concave connecting sections are arranged between two adjacent turbulent flow expansion joints. The utility model provides the corrugated tube which is provided with the turbulent flow expansion joints and can effectively prevent liquids from forming laminar flows in the pipe.
Description
Technical field
The utility model belongs to stainless steel pipe, particularly a kind of stainless steel wave pipe joint that is used for heat exchanger.
Background technology
At present, mostly the heat exchanger that is widely used in fields such as metallurgy, chemical industry, pharmacy is pipe heat exchanger, and heat exchanger tube is the important heat exchanger components of pipe heat exchanger.
The straight tube heat exchanger tube is the simplest heat exchanger tube, he be do not do any processing seam welded tube or seamless pipe directly will be arranged as heat exchanger tube, mainly there are two drawbacks in this heat exchanger tube: (1) is when heat exchange medium temperature or pressure change; Must cause the flexible of heat exchanger tube; Bigger pressure will be born in commissure, pipe two ends, occur the problem of pipe two ends weld cracking easily, (2) when the flow velocity of liquid in pipe slowly behind certain speed; Liquid in pipe will be laminar condition, influence the heat exchange effect.
Bellows is because retractable, solved pipe because the flexible problem that the variation of temperature or pressure causes,, and increased heat exchange area, but, can't cause the state of disturbance of fluid because ripple is overstocked, be difficult to solve laminar flow problem at all.
Summary of the invention
To above-mentioned technical problem, the utility model provide a kind of have flow-disturbing rise the joint, can effectively prevent liquid the pipe in formation laminar flow bellows tube.
The utility model is realized through following technical scheme:
The outer bellows tube of stainless steel, it comprises the stainless steel body, it is characterized in that: described stainless steel body is provided with a plurality of flow-disturbings joint that rises, and described adjacent flow-disturbing rises and is provided with the linkage section of indent between saving.
The flow-disturbing that on the stainless steel body, the is provided with joint that rises forms the space of an expansion in pipe, current advanced release in flow-disturbing rises by joint after the extruding of linkage section; Can effectively prevent the generation of laminar flow phenomenon; The flow-disturbing that is provided with the simultaneously joint that rises has effectively increased the mountain hot side and has amassed, and has improved heat dispersion.
Described linkage section is circular-arc.
In sum, the utility model is through being provided with a plurality of flow-disturbings joint that rises on the stainless steel body, and this section variation clocklike can make liquid in pipe always be in state of disturbance clocklike; Can prevent liquid genetic horizon flow phenomenon in pipe, the variation of the profile of stainless steel pipe has increased area of dissipation simultaneously; Therefore also improved the heat dispersion of pipe; Simultaneously be circular-arc, pipe can better be born from axially and stress radially, avoided the generation of stress concentration phenomenon at the adjacent flow-disturbing linkage section that is provided with between the joint that rises; Prolong the service life of heat exchanger tube, reduced maintenance cost and the workload that flies celestial workman.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Among the figure, 1 is body, and 2 are the flow-disturbing joint that rises, and 3 is linkage section.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further specified.
The outer bellows tube of stainless steel as shown in Figure 1, it comprises stainless steel body 1, it is characterized in that: described stainless steel body is provided with a plurality of flow-disturbings joint 2 that rises, and described adjacent flow-disturbing rises and is provided with the linkage section 3 of indent between the joint 2.
The flow-disturbing that on the stainless steel body, the is provided with joint that rises forms the space of an expansion in pipe, current advanced release in flow-disturbing rises by joint after the extruding of linkage section; Can effectively prevent the generation of laminar flow phenomenon; The flow-disturbing that is provided with the simultaneously joint that rises has effectively increased the mountain hot side and has amassed, and has improved heat dispersion.
Described linkage section 3 is circular-arc.
In sum, the utility model is through being provided with a plurality of flow-disturbings joint that rises on the stainless steel body, and this section variation clocklike can make liquid in pipe always be in state of disturbance clocklike; Can prevent liquid genetic horizon flow phenomenon in pipe, the variation of the profile of stainless steel pipe has increased area of dissipation simultaneously; Therefore also improved the heat dispersion of pipe; Simultaneously be circular-arc, pipe can better be born from axially and stress radially, avoided the generation of stress concentration phenomenon at the adjacent flow-disturbing linkage section that is provided with between the joint that rises; Prolong the service life of heat exchanger tube, reduced maintenance cost and the workload that flies celestial workman.
