The beneficial effect that the utility model produces is:
1, bellows heat transfer coefficient height.
Heat transfer coefficient is an important technology index of heat exchanger package, and the convection heat transfer' heat-transfer by convection on enhanced heat exchange surface is the effective measures that improve heat transfer coefficient.The augmentation of heat transfer of heat exchanger package is to realize by its unique ultra-thin-wall bellows, bellows is a kind of tangent continuously by circular arc, interior profile such as undulatory thin-walled tube, high official post fluid between its crest and trough has been subjected to strong disturbance, this disturbance is from the three-dimensional motion of outer fluid in the pipe, therefore the degree of its disturbance is more strong and thorough, even rate of flow of fluid is very low, also can make it become turbulence state, the thin thermograde of tube wall is little simultaneously, reduce wall resistance greatly, improved the inside and outside coefficient of heat transfer of pipe, thereby total heat transfer coefficient is improved.Generally can reach 1500～3500Kcal/ (m to water-heat transfer water
2H ℃), vapour-water can reach 2500～5000Kcal/ (m
2H ℃), be 2～4 times of straight tube.
2, energy-saving effect is remarkable.
The bellows velocity in pipes is generally 0.3～0.8m/s, average out to 0.55m/s, and straight tube is generally got 0.8～1.2m/s, and average out to 1.0m/s, therefore bellows is littler than straight tube fluid resistance under the identical situation of heat exchange amount, and power consumption is little.
3, antiscale, scale removal, anti-blocking performance are good.
It is more scabrous problem that heat exchanger package fouling, burn into are stopped up always, and particularly poor at condition of water quality, water treatment poor effect contain in the gas medium under the situation that impurity or chemical reaction easily generate foulant, and this problem is particularly outstanding.The lighter is worsened heat exchanger package function reduction, operating mode, resistance increases, energy consumption increases, and weight person then makes heat exchanger package block and can't move, so the workload that heat exchanger package is safeguarded, cleaned or upgrades increases.Because the special inside and outside waveform of bellows, Turbulence Media is constantly washed away the surfaces externally and internally of heat exchanger tube, dirt is difficult in the surface and stockpiles, even fouling, because bellows is a kind of flexible member, after being subjected to the effect of the temperature difference in the course of the work, the curvature of bellows each several part constantly changes, although it is not very greatly that this curvature changes the distortion that brings, but the linear expansion coefficient of dirt and metal bellows differs greatly, therefore will produce a bigger pulling-out force between dirt and the bellows surface, and be enough to make dirt to come off and realize cleaning automatically, automatic desludging, this point are that the heat exchange straight tube is incomparable.Can reach sufficient disturbance because pipe is outer in the pipe, the density-concentration longshore current body normal direction of runner inner fluid is arranged uniformly, the livings incrustation ion of therefore separating out from water and other impurity are all less than depositing and becoming dirty condition, being in operation the formation of dirt do not occur, so runner is always unobstructed.
4, stress distribution is even, anti-corrosion capability is strong.
Because bellows adopts unique forming technology, i.e. " free forming " or " soft shaping ".This process characteristic is: in forming process, distortion is not because the forced flow of metal in mould forms, but a kind of free-pouring process or be referred to as " soft shaping " process, this forming process is not owing to there is imposed deformation, can not cause stress to concentrate, residual stress is little, stress distribution is even, does not have the intergranular shortcoming, therefore has very strong anticorrosion stress-resistant ability.
5, the accommodate thermal expansion ability is strong.
Heat exchanger package adopts bellows, and each node of bellows all has the ability that is adapted to expand with heat and contract with cold, thereby the node heat exchanger tube can do very longly, and does not need the parts of expansion loop and so on, and is in service safe and reliable.
6, flow resistance is less.
Because having adopted augmentation of heat transfer, the coefficient of heat transfer of its raising is not to obtain by improving flow velocity, so the flow velocity inside and outside the corrugated tube heat exchanger group pipe is lower, thereby the flow resistance of corrugated tube heat exchanger group is less.
7, vibrationproof ability is strong.
Because heat exchanger tube is the node type, self has " plastic " property, as the sort of fixing self the vibrating frequently of rigid body, therefore, equipment is not in operation and has the antivibration antijamming capability, and the probability that vibration takes place is almost nil.
8, dynamic property is good.
Bellows so cause when velocity in pipes changes in load variations, does not influence the equipment heat exchange property because generation reinforcement disturbance flow rates is more than the 0.2m/s yet, and the user who is fit to load variations uses.
9, little, in light weight, the heatproof of volume, good pressure-resistant performance, suitable heat transferring medium is extensive, maintenance workload is little, safe and reliable.
10, because the heat exchanger tube header top of devaporizer heat exchanger package is provided with pressure equaliser, when the medium bubbing that flows in the system, gas can be got rid of automatically, system media is flowed keep continuity.Because the expansion that heats up when surpassing authorized pressure, can be got rid of a part of medium, keep system stability when system media.
