Description
Technical field
This utility model is related to technical field of heat exchangers, more particularly to a kind of concave surface heat exchanger tube that interlocks.
Background technology
At present the heat exchanger tube major part used in heat transmission equipment is plain tube, also there is some augmentation of heat transfer pipes, such as contract
Put pipe, band pipe, bellows tube etc..The shortcoming of plain tube is that convection transfer rate is little, and shaped telescopic tube, band pipe, bellows tube etc. are strong
Though the convective heat-transfer coefficient for changing heat-transfer pipe is improved, resistance also increases, easy fouling, and is situated between respectively for different heat transfers
Matter, narrow application range, at present than relatively low, the heat exchanger tube cooling medium of such as one-way spiral line exists the heat exchange efficiency of existing heat exchanger tube
Disturbed by helix during flowing, formed a certain degree of turbulent flow, increased heat transfer effect, but disturbance is less, at tube hub
Still with laminar flow flowing；Although and increase insert heat transfer effect in managing preferably, increased flow resistance, manage in addition in knot
It is difficult to clean after dirt.
Utility model content
The purpose of this utility model is to provide one kind and is applied to multiple fluid, the little easy cleaning of flow resistance and can improve body
Core flow is disturbed, and the good staggeredly concave surface heat exchanger tube of heat-transfer effect is solving the deficiency of prior art presence.
This utility model is achieved through the following technical solutions utility model purpose：
One kind is interlocked concave surface heat exchanger tube, including body, tube wall be provided with symmetrical left concave surface and right concave surface and
Laterally zygomorphic upper recess surface and concave surface, left concave surface and right concave surface are crisscross arranged with upper recess surface and concave surface, and inboard wall of tube body is corresponding
Symmetrical left convex surface and right convex surface and laterally zygomorphic upper convex surface and lower convex surface are formed, thus, is formed in body and pipe
The corresponding convex surface of external wall concave surface, makes the change of the size and Orientation generating period of body fluid velocity inside, enhances stream
The turbulent extent of body, the angle of velocity and temperature gradient vector diminishes in boundary region, and thermal field synergism is strengthened, and carries
High convection transfer rate.
Further, the left concave surface, right concave surface, upper recess surface and concave surface be hemispherical or semielliptical shape, all recessed
Face is smoothly connected with body Jing circular arcs.Due to all concave surfaces are hemispherical or semielliptical shape and with body pass through the smooth company of circular arc
Connect, fluid resistance is little, upper and lower, symmetrical all convex surfaces are formed in body makes fluid in body constantly change flowing side
To, it is less scaling, it is easy to cleaning.
Further, all concave surfaces of the tube wall are formed as base tube Jing is extruded with straight tube, are thus produced
Process is simple, cost is relatively low.
Further, the body is made by stainless steel tube or pure titanium seamless tubes, is applicable to the fluid of various properties, is prolonged
The service life of long heat exchanger tube.
Further, the concave surface pipeline section that interlocks is formed between the left concave surface and right concave surface and upper recess surface and concave surface, it is described
Staggeredly the concave surface pitch of concave surface pipeline section is 1～3 times of concave radius, and institute is with concave surfaces equivalently-sized, is thus made relative in body
The staggeredly convex surface pipeline section answered can continuously change fluid flow direction, enhance the heat transfer of center fluid in pipe.
Further, the quantity of the left concave surface, right concave surface, upper recess surface and concave surface is determined by the drop requirements of heat exchanger tube
It is fixed, it is uniformly distributed along tube length direction, quantity is very few can not to effectively improve convection transfer rate, and arranging excessively can larger fluid
The amplification of on-way resistance.
The staggeredly concave surface heat exchanger tube that this utility model is provided has advantages below：
1st, in the left and right of tube wall and the spherical concave surface that is crisscross arranged up and down, formed in body relative with tube wall concave surface
The spherical convex surface answered, makes the change of the size and Orientation generating period of body fluid velocity inside, enhances the turbulent flow journey of fluid
Degree, the angle of velocity and temperature gradient vector diminishes in boundary region, and thermal field synergism is strengthened, and improves convection current and changes
Hot coefficient.
2nd, it is smoothly connected because body upper recess surface and body are, fluid resistance is little, and in body in corresponding formation
Under, symmetrical spherical convex surface, tube fluid constantly changes flow direction, less scaling.
3rd, the concave surface pipeline section that interlocks is formed between left and right concave surface and upper and lower concave surface, staggeredly the concave surface pitch of concave surface pipeline section is 1
～3 times of concave radius, enable staggeredly convex surface pipeline section corresponding in body continuously to change fluid flow direction, enhance body
The heat transfer of interior center fluid.
