Description
Technical field
The utility model relates to the heat exchanger of the built-in spring of a kind of heat exchanger tube, is specifically related to the built-in segmented spring of a kind of heat exchanger tube heat exchanger.
Background technology
At present in chemical industry, the heat exchanger heat-exchange apparatus that is absolutely necessary, wherein shell-and-tube heat exchanger is the most general.In order to improve heat exchange efficiency, researchers strengthen from heat exchanger tube surface texture, insert disturbance strengthening, the many aspects such as extra electric field strengthening are studied, wherein insert strengthening is mainly take twisted strip and helical spring as main (strengthening disturbance by insert reinforcement technique conducts heat), this type of technology does not also overcome a difficult problem for resistance increment (being the resistance that insert brings), makes strengthening effect not obvious.As Chinese patent " pipe shell heat exchanger having heat exchange tube embedded with spring " (patent No.: CN200910060617.1) has provided a kind for the treatment of scheme, it by arranging a spring in heat exchanger tube, one end is fixed on the spring suspension of water inlet end face, the other end is freely placed near delivery port, although this scheme can augmentation of heat transfer, but heat-transfer effect is also bad, and flow resistance is excessive, and the stability of spring is bad.
Summary of the invention
The utility model, for the technical problem existing in above-mentioned prior art, provides the built-in segmented spring of a kind of heat exchanger tube heat exchanger, and this heat exchanger can effectively reduce flow resistance, strengthens disturbance, to improve heat transfer effect.
The utility model solves the technical scheme that its technical problem adopts:
The built-in segmented spring of a kind of heat exchanger tube heat exchanger, it mainly includes housing, heat exchanger tube, right end socket, left end socket and tube sheet, the two ends of described housing are tightly connected by tube sheet and right end socket and left end socket respectively, and the two ends of described heat exchanger tube are separately fixed on the tube sheet at housing two ends; It is characterized in that: the two ends in described heat exchanger tube are all furnished with a spring, two ports of described heat exchanger tube are equipped with spring suspension; Described spring is fixedly connected with spring suspension near one end of heat exchanger tube port, and the other end is freely put.
The length of described spring be heat exchanger tube length 2/7ths.
The specification of described spring is φ 25mm*0.8mm, and pitch is 3mm, and material is 0Cr18Ni9.
The vibration frequency of the described spring frequency mobile with fluid is consistent or reach unanimity.
Operation principle of the present utility model: the utility model makes fluid produce disturbance in the time entering heat exchanger tube, destroy boundary layer, porch, augmentation of heat transfer, in centre, complete turbulent flow section is in stable state, the effect of vibration that is subject to spring at heat exchanger tube outlet fluid produces disturbance again, destroy boundary layer, exit, thereby improve heat transfer effect.
Main beneficial effect of the present utility model is:
1, segmented spring of the present utility model is for existing not segmentation spring, when strengthening again the disturbance of heat exchanger tube inner fluid, because complete turbulent area, centre is there is no spring, therefore reduce widely fluid flow resistance, just at heat exchanger tube two ends region division spring, and produced disturbance by the convection flow body of spring, the convection current of fluid and tube wall fluid in promotion pipe, make boundary layer thickness attenuation, reduce thermal resistance, thereby further improve heat transfer efficiency;
2, the frequency mobile with fluid of the vibration frequency when spring in the utility model is consistent or while reaching unanimity, can there is covibration, the disturbance of enhance fluid, there is no spring place in the centre of heat exchanger tube simultaneously, owing to being fully development section of turbulent flow, the two ends that the dirt of wall can be washed into heat exchanger tube, not only can reduce fluid resistance coefficient augmentation of heat transfer in the method for two ends fixing spring like this, and effectively scale removal;
3, by the structure of spring is carried out to simple modifications, reduced widely resistance coefficient, improved heat transfer efficiency, and facilitate scale removal, maintenance and installation cost are low, do not need the extraneous energy of supplying with.Whole apparatus structure is simple, and installation and maintenance are convenient, and cost is low, good stability, and can save the energy, cleanliness without any pollution, has a wide range of applications.
