Abstract
The utility model discloses a spiral corrugated tube comprising spiral corrugated tube sections which are distributed at equal or different intervals. The spiral corrugated tube sections are connected through straight tube transition sections which are arranged in a spaced mode at corresponding angles. Therefore, the spiral corrugated tube can eliminate the laminar flow phenomenon caused by fluids, can form a uniform fluid temperature and density, and improves heat exchange efficiency of a heat exchange tube. Besides, the heat exchange area is enlarged, scaling is prevented from being generated, and service life is prolonged.
Description
Technical field
The utility model relates to the heat exchanger tube of heat exchanger, is a kind of helical form bellows tube specifically.
Background technology
At present, be applied to the heat exchanger tube in the heat exchanger, change into bellows by traditional straight tube, solved the impact that is subjected to temperature, pressure and have the characteristics of scalability, also increased heat exchange area simultaneously.But in application, also there is some problems.Overstocked such as line, the problem such as the state of disturbance of medium is not strong, and laminar flow layer is thicker.For addressing this problem, in disclosed technology, a kind of bellows tube is disclosed, it is that a plurality of flow-disturbing bulge loops are serially connected on the straight tube, and is connected the junction with straight tube at the flow-disturbing bulge loop and circular arc is set connects.Like this, make it the variation that each section bellows tube is rule, by arc transition, reduced axially and stress radially, also be subject to washing away of fluid because the flow-disturbing bulge loop that has makes bellows tube simultaneously, eliminated forming the possibility that fouling is stopped up.But, owing to be between the sideline of each node bulge loop pipeline section that straight tube forms and straight length longitudinal end, to be vertical node section.Therefore in actual application, unique deficiency be that flow disturbance is less when MEDIA FLOW is crossed straight length, also can produce laminar flow layer, can not fully form flow-disturbing, its heat transfer effect is subject to certain impact.
Summary of the invention
In view of above-mentioned present situation, the utility model provides a kind of helical form bellows tube, has thoroughly eliminated the existence of heat exchanger tube internal layer fluid layer, has greatly strengthened heat transfer effect.
The technical solution of the utility model is: a kind of helical form bellows tube, and the helical form node pipeline section that has equidistantly or equidistantly do not arrange, the straight length changeover portion that corresponding angle of inclination is arranged by the interval between each helical form node pipeline section connects.
Therefore, when fluid flowed in the heat exchanger tube that the helical form bellows tube forms, the inclination position of arbitrary heat exchanger tube of process changed, so that the heat exchanger tube inner fluid fully forms flow-disturbing, there is not laminar condition, can forms uniform fluid temperature (F.T.) and density, strengthen the heat exchange efficiency of heat exchanger tube.
During this was novel, the inclination angle of described helical form node pipeline section was 5 °-25 °.
In a word, the helical form bellows tube that this is novel is by to each other evenly certain angle of inclination, the effectively generation of eliminate laminar flow of each helical form node pipeline section.Therefore, also have and increased heat exchange area, avoid the generation of fouling, improved the heat exchange efficiency of heat exchanger tube.
Description of drawings
Accompanying drawing is this novel schematic diagram.
The specific embodiment
Below in conjunction with the accompanying drawing example to this novel being described further.
See a kind of helical form bellows tube shown in the drawings, comprise helical form node pipeline section 1 and the straight length that corresponding angle of inclination is arranged 2 changeover portions at interval connect and compose between each helical form node pipeline section 1 heat exchanger tube.In this was novel, described each helical form node pipeline section 1 was the configuration at certain angle of inclination with respect to straight length 2, and the two ends of this helical form bellows tube are straight tube 3 installation ends.This is novel by helical form node pipeline section 1, avoids concentrating the generation laminar flow to strengthen heat exchange efficiency.During this was novel, the inclination angle of mentioned helical form node pipeline section 1 was 5 °-25 °.
Above-described embodiment, except the helical form node pipeline section 1 of mentioning is equidistant mode of arranging, according to application characteristic, the equidistant arrangement of its helical form node pipeline section 1 all right right and wrong, all can satisfy instructions for use.
This novel helical form node pipeline section 1 is to adopt integral one-step molding.
Claims (2)
1. a helical form bellows tube is characterized in that, the helical form node pipeline section (1) that has equidistantly or equidistantly do not arrange, and the straight length that corresponding angle of inclination is arranged (2) changeover portion by the interval between each helical form node pipeline section connects.
