Abstract
The utility model discloses a kind of nodal type heat exchanger tube, the integral pipe that it is made up of jointly pipe joint, groove and pipe joint.Described pipe joint is positioned at the two ends of pipeline, and remaining pipeline is separated into pipe joint by the groove equidistantly arranged.The width of described groove is shorter than the length of pipe joint, and the wall thickness of the wall ratio pipe joint of groove is thin.The utility model nodal type heat exchanger tube is because of the alternate effect of groove, and axial cross section integration section changes, and makes to manage outer medium and constantly changes the flow direction, easy turbulization, turbulent flow can stir medium side interlayer, reduces wall resistance, improve heat transfer boundary condition, also there is scale removal and anti-scaling action simultaneously.Advantage on the other hand still retains that straight pipe type parallel operation is sturdy and durable, security performance good, feature applied widely.
Description
Technical field
The utility model relates to a kind of heat exchange element, and specifically, the utility model relates to a kind of nodal type heat exchanger tube of supporting heat exchanger.
Background technology
Most of manufacturing industry all can't do without supporting heat exchanger in production technology, and particularly the industry such as petrochemical industry, light textile uses heat exchanger in a large number.Heat exchanger is a kind of energy conversion, and its performance determines the efficiency, quality and the production cost that form a complete production network.In current engineering heat exchanger structure pattern mainly contain board-like, helix tube type and straight pipe type etc., wherein applying maximum is straight tubular heat exchanger, the heat exchanger feature of this kind of traditional structure is that structure is simple, making is easy, and it is sturdy and durable, safe and reliable, the most important thing is that application conditions is not high, be almost applicable to every profession and trade heat exchange occasion.But traditional straight tubular heat exchanger also Shortcomings, subject matter is that volume is large, manufacturing cost is relatively high, and heat exchange efficiency is not high enough, easily fouling in tube side.The problem of these objective realities must affect user and support the use benefit, and particularly tube side fouling causes heat exchanger effectiveness to decline, and this situation, except increasing energy consumption, also reduces work efficiency.Under normal circumstances, straight pipe type heat exchanger tube tube side latus rectum is little, and snaking difficulty is large, and snaking cost is large.
Utility model content
The utility model is mainly for the deficiency of existing straight pipe type heat exchanger tube, a kind of nodal type heat exchanger tube is proposed, this effective smooth wall straight tube spinning forms, structure is simple, manufacturing technology is ripe, and when using, surface is less scaling, heat exchange efficiency is high, the axial displacement produced because of medium temperature change when particularly running can automatic compensating.
The utility model is achieved through the following technical solutions technical goal.
Nodal type heat exchanger tube, its improvements are: the integral pipe that it is made up of jointly pipe joint, groove and pipe joint.Described pipe joint is positioned at the two ends of pipeline, and remaining pipeline is separated into pipe joint by the groove equidistantly arranged.The width of described groove is shorter than the length of pipe joint, and the wall thickness of the wall ratio bellows tube of groove is thin.
As further improvement project, the width of described groove is shorter than the length of pipe joint by 1/5 ~ 1/2.
As further improvement project, the thin 0.4mm ~ 1.0mm of described groove walls thickness rate pipe joint wall thickness.
As further improvement project, the axial cross section of described groove is circular arc, and hollow depth is 1mm ~ 2mm.
The utility model compared with prior art, has following good effect:
1, nodal type structure is simple, shaping is easy;
2, nodal type heat exchanger tube is under bore, length the same terms, and larger than light wall straight tube heat exchange area, heat exchange efficiency is high;
3, nodal type heat exchanger tube is identical by groove, and interrupted contracted section makes the outer medium stream of pipe constantly change the flow direction, easy turbulization, and turbulent flow can stir medium side interlayer, reduces wall resistance, improves heat transfer boundary condition, also has scale removal, anti-scaling action simultaneously;
4, nodal type heat exchanger tube has nose balance ability, and the runtime, full performance was good.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Nodal type heat exchanger tube shown in Fig. 1, it forms integral pipe jointly by pipe joint 1, groove 2 and pipe joint 3.Described pipe joint 1 is the extension tube attached of nodal type heat exchanger tube, this Duan Guanwei circular light wall straight tube.Outside removing pipe joint 1, remaining pipeline is separated into pipe joint 3 by the arc groove 2 equidistantly arranged.In order to improve the heat exchange efficiency of managing outer medium, the width of groove 2 is shorter than the length of pipe joint 3, and the present embodiment nodal type heat exchanger tube nominal bore is 19mm, and the long 20mm of every Multi-joint hose 3, then the width value 5mm of groove 2, both differ 15mm.Because groove 2 is roll milling formings, therefore the wall thickness of the wall ratio pipe joint 3 of groove 2 is thinner, and in the present embodiment, the wall thickness of pipe joint 3 is 2mm, then the wall thickness of fluted 2 is 1.5mm.In order to improve the flow direction of managing outer medium, reduce liquid resistance, groove 2 axial cross section in the present embodiment is circular arc, circular arc hollow depth 1mm.The utility model is under bore, length the same terms, larger than light wall straight tube heat exchange area, heat exchange efficiency is high, can under the prerequisite not increasing comb tube pitch, realize increasing heat exchange area, the wall ratio pipe joint 3 of adding groove 2 is thinner, and namely the rigidity of groove 2 is less than pipe joint 3, has certain nose balance ability.When the temperature of heat transferring medium changes, nodal type heat exchanger tube produces corresponding axial displacement and then carrys out automatic compensating by groove 2 distortion, and can eliminate internal stress thus, this function is conducive to heat exchanger safe operation.
The utility model nodal type heat exchanger tube is because of the alternate effect of groove 2, and axial cross section integration section changes, and makes to manage outer medium stream and constantly changes the flow direction, easy turbulization, turbulent flow can stir medium side interlayer, reduces wall resistance, improve heat transfer boundary condition, also there is scale removal and anti-scaling action simultaneously.On the other hand advantage still retains that straight tubular heat exchanger is sturdy and durable, security performance good, feature applied widely.
