Abstract
The utility model discloses a kind of heat exchanger tube of rod baffle heat exchanger, this heat exchanger tube comprises heat exchange tube body, described heat exchange tube body is made up of the straight length at two ends and the convergent-divergent node section at middle part, convergent-divergent node section is connected and composed in turn by multiple convergent-divergent node, each convergent-divergent node is made up of coaxial amplification Taper Pipe and contraction Taper Pipe, be provided with convergent-divergent node section and strengthen groove with axial screw at the outer surface of convergent-divergent node section tube wall, the pitch of spiral strengthening groove is the length of a convergent-divergent node, the cross section of described spiral strengthening groove is circular arc, the degree of depth of spiral strengthening groove is less than 1/2nd of heat exchanger tube wall thickness, the heat exchanger tube of this rod baffle heat exchanger can be strengthened the heat transfer effect of tube side and shell side medium simultaneously, heat exchange efficiency is high.
Description
Technical field
The utility model relates to technical field of heat exchangers, especially relates to a kind of heat exchanger tube of rod baffle heat exchanger.
Background technology
It is high that rod baffle heat exchanger has heat exchange efficiency compared with common tube shell heat exchanger, and shell side flow velocity is high, without advantages such as dead bands, is widely used in gas-gas, gas-liquid, liquid-liquid heat exchanger and vapour phase condensation process.The heat exchanger tube that rod baffle heat exchanger of the prior art assembles mostly is light pipe, interior ripple male-pipe, camber line pipe, helix tube, shaped telescopic tube etc., these heat exchanger tubes conduct heat time except shaped telescopic tube, all less to managing the strengthening effect of interior medium, but to shell side medium, the cross-flow in heat exchanger is difficult to play invigoration effect to this common shaped telescopic tube.
Utility model content
The technical problem that utility model will solve is: a kind of heat exchanger tube of rod baffle heat exchanger is provided, and the heat exchanger tube of this rod baffle heat exchanger can be strengthened the heat transfer effect of tube side and shell side medium simultaneously, and heat exchange efficiency is high.
The technical scheme that technical solution problem is taked: a kind of heat exchanger tube of rod baffle heat exchanger, comprise heat exchange tube body, described heat exchange tube body is made up of the straight length at two ends and the convergent-divergent node section at middle part, convergent-divergent node section is connected and composed in turn by multiple convergent-divergent node, each convergent-divergent node is made up of coaxial amplification Taper Pipe and contraction Taper Pipe, is provided with convergent-divergent node section and strengthens groove with axial screw at the outer surface of convergent-divergent node section tube wall.
As improvement of the present utility model: the pitch of spiral strengthening groove is the length of a convergent-divergent node.
As further improvement of the utility model: the cross section of described spiral strengthening groove is circular arc.
Further improve again as of the present utility model: the degree of depth of spiral strengthening groove is less than 1/2nd of heat exchanger tube wall thickness.
Improve as another kind of the present utility model: described spiral strengthening groove is the multi-head spiral strengthening groove coaxial with convergent-divergent node section.
As preferred plan of the present utility model: multi-head spiral strengthening groove is made up of the left-handed spiral strengthening groove and the right hand helix strengthening groove that wait number.
Beneficial effect: the heat exchanger tube of rod baffle heat exchanger of the present utility model is because the heat exchanger tube that has adopted described rod baffle heat exchanger comprises heat exchange tube body, described heat exchange tube body is made up of the straight length at two ends and the convergent-divergent node section at middle part, convergent-divergent node section is connected and composed in turn by multiple convergent-divergent node, each convergent-divergent node is made up of coaxial amplification Taper Pipe and contraction Taper Pipe, be provided with and the technical scheme of convergent-divergent node section with axial screw strengthening groove at the outer surface of convergent-divergent node section tube wall, make the heat exchanger tube of rod baffle heat exchanger of the present utility model can be by the structure-reinforced tube side heat transfer effect of convergent-divergent node time, utilize the heat transfer effect of the spiral strengthening groove strengthening shell side of heat exchange outer surface of tube wall, the more common heat exchanger tube without strengthening groove improves heat exchange efficiency and reaches 20%, because the pitch that has adopted described spiral strengthening groove is the feature of the length of a convergent-divergent node, make to strengthen groove being more evenly distributed on node, heat-transfer effect is better, and is beneficial to processing, be 1/2nd the technical characterictic that the degree of depth of circular arc, spiral strengthening groove is less than heat exchanger tube wall thickness owing to having adopted the cross section of described spiral strengthening groove, in improving heat transfer effect, reduce to strengthen the impact of groove exchange heat pipe intensity, be the multi-head spiral strengthening groove coaxial with convergent-divergent node section owing to having adopted described spiral strengthening groove, further increase heat exchange tube wall external surface area, make shell side heat exchange strengthening effect better, owing to having adopted multi-head spiral strengthening groove by waiting the left-handed spiral strengthening groove of number and the technical characterictic that right hand helix strengthening groove forms, form the strengthening groove of distributed in grid at heat exchange outer surface of tube wall, not only improve the strengthening effect of shell side, and can avoid heat exchanger tube torsional deformation.
