The included angle among three parallel spiral grooves is 120 degrees. The depth of the spiral grooves of the triple wave-form heat exchange tube t is 0.5 to 3mm. The thread pitch of the triple wave-form heat exchange tube B is 15 to 60mm, and the helical angle Alpha is 20 to 75 degrees, and the wall thickness is 0.8 to 3.0MM. The plain tube part of the triple wave-form heat exchange tube length L is L 40 to 250mm. The OD of the triple wave-form heat exchange tube d is 12 to 45mm. The utility model has the advantages of stable and reliable structure, easy manufacture, high strength, uneasy leakage, and low cost. Compared with the existing heat exchanger, the utility model also has the advantages of long service life and wide application range.
Description
Technical field the utility model relates to a kind of improved heat exchanger, refers in particular to a kind of three bow wave line heat exchanger tubes, and the utility model should be divided into the F28D group in International Patent Classification (IPC).
Background technology is present, in order to improve the heat exchange efficiency of heat exchanger, various forms of heat exchangers have been adopted, the heat exchange efficiency of these heat exchangers improves, but present heat exchanger has remained weak point: heat exchange efficiency is still not high enough, has influenced the capacity of equipment to a certain extent.Equipment making gets compactness inadequately under certain heat output and energy consumption prerequisite, thereby consumptive material is many, it is big to take up an area of.In addition, existing heat exchanger requires and can not adapt to some special process of fast heat, chilling.In addition, also there are shortcomings such as easy fouling, service life be short in present heat exchanger.
Summary of the invention goal of the invention of the present utility model is: at the deficiency of prior art, provide a kind of heat exchange efficiency higher, can satisfy that require, long service life, the less scaling three new-type bow wave line heat exchanger tubes of some special process.
Goal of the invention of the present utility model is to realize by following technical scheme:
Three helix grooves that are parallel to each other are arranged on the interlude of described heat exchanger tube, one section light pipe section is respectively arranged at the two ends of described heat exchanger tube.
In specific embodiment:
Described three helix grooves that are parallel to each other are in 120 degree angles.
The groove depth t=0.5-3mm of the helix groove of described three bow wave line heat exchanger tubes.
The pitch B=15-60mm of described three bow wave line heat exchanger tubes.
The pitch angle alpha will of described three bow wave line heat exchanger tubes=20-75 degree.
The wall thickness of described three bow wave line heat exchanger tubes equals 0.8-3.0mm.
Length L=the 40-250mm of described three bow wave line heat exchanger tube light pipe sections.
Outside diameter d=the 12-45mm of described three bow wave line heat exchanger tubes.
Because the utility model has adopted above-mentioned technical scheme, realizes augmentation of heat transfer by the internal and external screw wire casing, its heat transfer coefficient is significantly improved.Because the inside and outside medium of pipe forms strong periodic disturbance to tube wall and reason such as washes away, incrustation scale can't be formed, thereby improved the life-span of heat exchanger tube.
Description of drawings describes the utility model below in conjunction with accompanying drawing:
Accompanying drawing is the front view of three bow wave line heat exchanger tubes described in the utility model.
The interlude of described three bow wave line heat exchanger tubes has three helix grooves that are parallel to each other, and at the two ends of described heat exchanger tube one section light pipe section is arranged respectively.Because the light pipe section in the light pipe section on right side and left side is similar among the figure,, the light pipe section on right side is not drawn for the ease of three helix grooves that are parallel to each other that show that three bow wave line heat exchanger tube interludes are had.
The specific embodiment further specifies the utility model below in conjunction with drawings and Examples: in the front view of described three bow wave line heat exchanger tubes, three helix grooves that are parallel to each other are arranged on described heat exchanger tube interlude, one section light pipe section is respectively arranged at the two ends of described heat exchanger tube.In specific embodiment: described three helix grooves that are parallel to each other are in 120 degree angles.The groove depth t=0.5-3mm of the helix groove of described three bow wave line heat exchanger tubes.The pitch B=15-60mm of described three bow wave line heat exchanger tubes.The pitch angle alpha will of described three bow wave line heat exchanger tubes=20-75 degree.The wall thickness of described three bow wave line heat exchanger tubes equals 0.8-3.0mm.Length L=the 40-250mm of described three bow wave line heat exchanger tube light pipe sections.Outside diameter d=the 12-45mm of described three bow wave line heat exchanger tubes.
The utility model can also can be made by copper or other metal by the stainless steel manufacturing.
Operation principle of the present utility model is as follows:
The heat transfer of three bow wave line heat exchanger tubes realizes by its internal and external screw wire casing.When medium flowed inside and outside this three bow waves line heat exchanger tube, because the effect of helix groove makes the fluid retention bottom near wall produce periodic disturbance, the described cycle was decided by the spiral fluted structure.Because periodic disturbance causes segment fluid flow to form eddy current along the helix groove rotation, thereby has reduced the thickness of fluid boundary layer, thereby has strengthened turbulent extent, improved the inside and outside convection transfer rate of pipe greatly.When pipe is outer when being the steam condensation, helix groove becomes the passage of condensate drainage, thus attenuate condensate film, reduced thermal resistance, improved the condensation heat transfer coefficient, so heat transfer coefficient is higher, the interior stream of three bow wave line heat exchange tubes also can form self-excited vibration.Therefore the inside and outside convection transfer rate of pipe can be up to 1200W/m
2℃, more former corrugated tube heat exchanger overall heat-transfer coefficient improves 1-3 doubly.Because the inside and outside medium of three bow wave line heat exchange tubes forms strong periodic disturbance to tube wall and washes away,, make heat exchanger tube have the self-cleaning action that incrustation scale can't form in addition in the self compensation ability of this heat exchanger tube.Under identical operating mode, more original bellows fouling degree decline 20%-30%.Prolonged the service life of heat exchanger tube.The science design as the case may be of the size of three bow wave line heat exchanger tubes and concrete structure is suitably regulated, to reach best heat-transfer effect.
Experimental results show that: the utlity model has Stability Analysis of Structures reliable, make easily, intensity is high, be difficult for The advantage that leak, production cost is low. Compare with original heat exchanger, the utility model also has use The advantage of life-span length, applied range.
