Abstract
The utility model discloses a kind of corrugated tube, it includes corrugated stainless steel tubing and the length located at corrugated stainless steel tubing two ends is more than or equal to 100mm lengthening joint, corrugated stainless steel tubing includes the connecting portion and some crests and trough between two connecting portions at two ends, crest is arranged at intervals with trough, the cross section profile of crest and trough is in large semi-circular, connecting portion is the crest flattened along corrugated stainless steel tubing axis direction, and the connecting portion of lengthening joint end and corrugated stainless steel tubing is weldingly connected.Compared with prior art, the utility model proposes corrugated tube have effective heat exchange area big, cause to be less likely to occur residual phenomena during trandfer fluid material, the joint at bellows two ends is longer, be conducive to the advantage through thicker heat-insulation layer or other spaces.
Description
Technical field
The utility model is related to Bellows Technology field, and in particular to a kind of corrugated tube.
Background technology
Corrugated tube belongs to a kind of tube heat exchanging component, and its architectural feature is axial undulate.One is matched in engineering
The corrugated tube of race's parallel spaced-apart arrangement constitutes the corrugated tube heat exchanger of dimension, and the heat exchanger of the type has structure letter
The features such as single, heat exchange efficiency height, automatic elimination axial stress.In order to further improve the heat transfer effect of corrugated tube heat exchanger,
Fixed point suit deflection plate in every corrugated heat-exchange pipe outer wall, using the barrier effect of deflection plate, guiding medium is changed in adjacent corrugations
Olderly flowage between heat pipe.Because of the axial undulate of the tube wall of corrugated tube, it has more than the compensator of other structures type
There is nose balance ability, internal stress can be eliminated significantly.Existing corrugated tube effective heat exchange area is small, and crest, trough point partially are not
It is round and smooth, easily remained during trandfer fluid material, the joint at bellows two ends is shorter, be unfavorable for through thicker heat-insulation layer or
Other spaces.Therefore, it is necessary to propose a kind of new technical scheme to solve these problems.
Utility model content
The utility model proposes a kind of corrugated tube, effective heat exchange area is small in the prior art for solution, and crest, trough are inclined
Point is not round and smooth, causes easily to remain during trandfer fluid material, the joint at bellows two ends is shorter, is unfavorable for through thicker
The problem of heat-insulation layer or other spaces.
To achieve these goals, the technical solution of the utility model is realized in：A kind of corrugated tube, including
Corrugated stainless steel tubing and lengthening joint of the length more than or equal to 100mm located at corrugated stainless steel tubing two ends, the stainless steel wave
Line pipe includes the connecting portion and some crests and trough between two connecting portions at two ends, and the crest is set with trough interval
Put, the cross section profile of the crest and trough is in large semi-circular, and the connecting portion is along the corrugated stainless steel tubing axis side
To the crest of pressing, the lengthening joint end and the connecting portion of the corrugated stainless steel tubing are weldingly connected.
It is preferred that, the pitch of waves of the corrugated stainless steel tubing is less than or equal to 3.5mm.
It is preferred that, the wall thickness of the corrugated stainless steel tubing is less than or equal to 0.2mm.
It is preferred that, the length of the lengthening joint is more than or equal to 120mm.
Compared with prior art, the utility model tool has the advantage that：The utility model proposes corrugated tube ripple
The cross section profile of peak and trough is in large semi-circular, and effective heat exchange area is big, and heat exchange property is good, is also beneficial to fluid conveying, no
Easily there are fluid residuals, additionally use the lengthening joint that length is more than or equal to 100mm, be conducive to its through thicker heat-insulation layer or its
Its space.Compared with prior art, the utility model proposes corrugated tube have effective heat exchange area big, cause trandfer fluid
It is less likely to occur residual phenomena during material, the joint at bellows two ends is longer, is conducive to through thicker heat-insulation layer or other skies
Between advantage.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the accompanying drawing used required in description of the prior art is briefly described, it should be apparent that, drawings in the following description are only
It is some embodiments of the present utility model, for those of ordinary skill in the art, is not paying the premise of creative work
Under, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is front view of the present utility model.
In figure：1- corrugated stainless steel tubings, 2- lengthening joints, 11- connecting portions, 12- crests, 13- troughs.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is paid
The every other embodiment obtained, belongs to the scope of the utility model protection.
As shown in figure 1, the utility model proposes a kind of corrugated tube, including corrugated stainless steel tubing 1 and located at not
The length at rust corrugated steel pipe 1 two ends is more than or equal to 100mm lengthening joint 2, and the lengthening joint 2 for being not less than 100mm using length is favourable
In the corrugated tube through thick heat-insulation layer or other space mountings, corrugated stainless steel tubing 1 include the connecting portion 11 at two ends with
And some crests 12 and trough 13 between two connecting portions 11, crest 12 is arranged at intervals with trough 13, crest 12 and trough
13 cross section profile is in large semi-circular, and the effective heat exchange area of such heat exchanger tube is big, and heat exchange efficiency is high, is also beneficial to fluid defeated
Send, do not easily cause fluid residuals.Connecting portion 11 is the crest 12 flattened along the axis direction of corrugated stainless steel tubing 1, the end of lengthening joint 2
It is weldingly connected with the connecting portion 11 of corrugated stainless steel tubing 1.
As shown in figure 1, in the present embodiment, the pitch of waves of corrugated stainless steel tubing 1 is less than or equal to 3.5mm.Corrugated stainless steel tubing 1
Wall thickness is less than or equal to 0.2mm, so that body is more soft, is easily installed connection, adds because temperature change causes heat
The deformation-compensated ability of swollen shrinkage.
As shown in figure 1, in the present embodiment, the length of lengthening joint 2 is more than or equal to 120mm.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Within the spirit and principle of utility model, any modification, equivalent substitution and improvements made etc. should be included in the utility model
Protection domain within.
