Description
Technical field
The utility model relates to a kind of heat exchange element, especially a kind of heat exchanger tube of shell-and-tube heat exchanger.
Background technology
Shell-and-tube heat exchanger is also known as tubular heat exchanger, and it is comparatively simple that this heat exchanger has structure, and operation is reliable, and the advantage such as to use under high temperature, high pressure, be heat exchanger most widely used at present.Shell-and-tube heat exchanger of the prior art is in order to improve heat exchange efficiency, many employings have the heat exchanger tube of threaded interior walls, but, due in shell-and-tube heat exchanger, the summation of whole heat exchanger tube sectional area is far longer than the tube side import sectional area on housing, therefore, in actual heat transfer process, in heat exchanger tube, the flow velocity of medium usually can not reach and forms the flow velocity of turbulent flow, and the improvement of its heat exchange efficiency is also not obvious.CN1190647C discloses a kind of pipeline section and/or the pipeline section cross section thermoexcell in abnormity, and this heat exchanger tube adopts and combined by the pipeline section of different cross section shape, forms heat exchanger tube, not only increases heat exchange efficiency, and effectively can prevent in-tube fouling.But because the cross sectional shape of this heat exchanger tube is complicated, actual production difficulty is comparatively large, and therefore, this heat exchanger tube is seldom employed in shell-and-tube heat exchanger.CN 102102957 A discloses a kind of Oblate staggered pipe for heat exchanger, and this heat exchange tube structure is comparatively simple, but in heat transfer process, the heat transferring medium in pipe not easily arrives corner location, and heat transfer effect is undesirable.
Utility model content
The technical problem that utility model will solve is: provide a kind of oblate crisscross heat exchanger tube, this oblate crisscross heat exchange tube structure is simple, and heat transferring medium is easy to form turbulent flow in heat exchanger tube, and heat exchange efficiency is high.
The technical scheme that technical solution problem is taked: a kind of oblate crisscross heat exchanger tube, the two ends of the crisscross heat exchanger tube of described oblateness are pipe section, middle part is oblate pipeline section, oblate pipeline section is made up of the oblate pipeline section of longitudinal direction in right-angled intersection and horizontal oblate pipeline section, longitudinally oblate pipeline section and horizontal oblate pipeline section equal length are crisscross arranged, the oblate pipeline section of described longitudinal direction and laterally oblate pipeline section are surrounded by the plane tube wall of two symmetries and two symmetrical two arc tube walls, interior rhombus flow-disturbing outstanding in pipe is suppressed with protruding in plane tube wall center, also disturbing flow device is provided with in the crisscross heat exchanger tube of oblateness, described disturbing flow device is the flow-disturbing steel bar arranged along oblate crisscross heat exchanger tube axis, steel bar is provided with the symmetry corresponding with plane tube wall rhombus flow-disturbing raised position protruding.
As improvement of the present utility model: described disturbing flow device is the spiral spoiler arranged along oblate crisscross heat exchanger tube axis, and the axis of spiral spoiler is provided with support fixed leg.
Beneficial effect: the crisscross heat exchanger tube of oblateness of the present utility model, because the two ends that have employed the crisscross heat exchanger tube of described oblateness are pipe section, middle part is oblate pipeline section, oblate pipeline section is made up of the oblate pipeline section of longitudinal direction in right-angled intersection and horizontal oblate pipeline section, longitudinally oblate pipeline section and horizontal oblate pipeline section equal length are crisscross arranged, the oblate pipeline section of described longitudinal direction and laterally oblate pipeline section are surrounded by the plane tube wall of two symmetries and two symmetrical two arc tube walls, interior rhombus flow-disturbing outstanding in pipe is suppressed with protruding in plane tube wall center, also disturbing flow device is provided with in the crisscross heat exchanger tube of oblateness, described disturbing flow device is the flow-disturbing steel bar arranged along oblate crisscross heat exchanger tube axis, on steel bar, corresponding flat tube wall rhombus flow-disturbing high spot is provided with symmetrical protruding technical scheme, make the crisscross heat exchange tube structure of oblateness of the present utility model simple, be easy to manufacture, heat transferring medium in pipe fully can arrive each corner in oblate pipe, and heat transferring medium is under the effect of disturbing flow device, comparatively low flow velocity state also can form turbulent flow, heat exchange efficiency is high, be the spiral spoiler arranged along oblate crisscross heat exchanger tube axis owing to have employed described disturbing flow device, the axis of spiral spoiler is provided with the technical characteristic supporting fixed leg, further increase the effect of flow-disturbing, make heat transfer effect better, support fixed leg on spiral spoiler adds the intensity of spoiler, makes heat exchanger tube work of the present utility model more stable, reliable.
