Description
Technical field
The utility model relates to field of heat exchangers, particularly relates to twisted tube heat exchanger.
Background technology
Heat exchanger is a kind of energy-saving equipment realizing heat transmission between material between two or more fluid of different temperatures, make heat pass to the lower fluid of temperature by higher fluid, fluid temperature (F.T.) is made to reach flow process set quota, to meet the needs of process condition, simultaneously also one of capital equipment improving energy utilization rate.
Shell-and-tube heat exchanger is the product that an amount is large and various in style, in the urgent need to new wear-resistant, corrosion-resistant, high-strength material.There is progress in various degree in China in nonmetallic materials such as development stainless steel copper alloy composite material, almag and carborundum etc., wherein especially very fast with the development of titanium material.Titanium has good resistance to corrosion to seawater, chlor-alkali, acetic acid etc., and as augmentation of heat transfer again, effect will be better, and some manufacturers have grasped the processing and manufacturing technology of titanium material preferably.To the spraying of material, China is from external introduction of production line.Almag has higher corrosion resistance and thermal conductivity, and cost ratio titanium material is cheap, should note.Domesticly in energy efficiency etc., improve heat exchanger performance, improve heat transfer efficiency, reduce heat transfer area and reduce pressure drop, the research improving the aspects such as device calorific intensity achieves important achievement.A large amount of uses of heat exchanger effectively raise the utilization rate of the energy, and entreprise cost is reduced, and benefit improves.
Heat exchanger is widely used in various industrial circle, is the visual plant realizing heat transfer technological requirement.Often double pipe heat exchanger is adopted in the fields such as heat pump, air-conditioning, HVAC.What generally adopt in prior art be double pipe heat exchanger is one or a few light pipe in-built in an outer tube, but the heat transfer efficiency of this heat exchanger is general lower; This kind of heat exchanger is when making coaxial spiral sleeve pipe pattern in addition, needs support member to ensure coaxially and not to damage in outer tube.
Current manufacture heat exchanger heat exchanger tube used is all round tube, support that heat exchanger tube is not be exactly with rod baffle or deflecting fence with deflection plate, the pressure drop of shell-side fluid is increased, the energy consumed is also many, meanwhile, fluid, based on advection, easily produces stagnant area, and dirt is formed on heat exchanger tube and heat exchanger tube support member, affect heat transfer effect.The utility model adopts torsion heat exchange pipe, and two media spirality flows through, and formation is streamed, and reaches enhanced heat exchange effect, and meanwhile, fluid washes away the deposition that can prevent dirt to tube wall.
Have one to be that interior pipe adopts multi-start helical tubes again, the multi-head spiral shape design of interior pipe uniqueness makes fluid form eddy flow in multiple minor spiral passage between inner and outer pipes, can play the effect of augmentation of heat transfer, and in technique, ensure that inner and outer pipes is coaxial; But because passage is little, this kind of heat exchanger often resistance is very large, and often differ greatly due to its both sides channel cross-section, therefore the heat exchange of water and cold-producing medium can only be used for.
Research data shows: oval twisted tube is used for general shell and tube exchanger and has higher heat transfer coefficient, and under the same conditions, flow resistance is less, and overall performance is better, is a kind of product having potentiality to be exploited.But due to the relation of production technology, oval twisted tube domestic production producer is less, oval twisted tube is adopted to be that the coaxial heat exchanger of interior pipe does not see product at present.
Therefore, effectively improve the heat transfer efficiency of the coaxial heat exchanger of prior art, expand the range of application of process fluid, and significantly do not increase the major issue that resistance becomes making coaxial heat exchanger.
